The present disclosure relates to assemblies, apparatuses, systems, and methods for extracting material from a source of the material and conveying material to a desired location and, more particularly, to assemblies and methods for extracting material from environments providing sources for the material and conveying material to elevated positions.
Certain environments, such as, for example, work sites, industrial sites, commercial sites, residential sites, or natural sites, may often be sources of material that is either deposited or accumulates as a result of operations at the site or through natural accumulation. The deposit or accumulation of the material may be undesirable for a number of reasons, and thus, removal of the material from the site may be desirable or necessary. For example, the presence of the material in sufficient quantities may hinder operations at the site, may present an undesirable environmental condition, and/or may present recycling or remediation opportunities. Traditional approaches to remove the material from the site and/or to deposit the material may be unsatisfactory or suffer from drawbacks for various reasons. For example, the material may include a variety of material types (e.g., packing material, chemical fillers, insulation, etc.) or material forms (e.g., liquids, solids, emulsions, particulates, etc.), and/or the material may be located or positioned, such that it is difficult to efficiently extract the material from the site. In some instances, it may be desirable to convey a material to a desired location, for example, in large quantities and/or in an efficient manner. For example, it may be desirable to convey a material to an elevated position relative to a source of the material. This may be desirable, for example, when supplying material to the top or upper portion of a tower, such as a refinery tower. Traditional methods of extracting and/or conveying material may be impracticable, inefficient, unduly time consuming, and/or labor intensive.
Accordingly, Applicant has recognized a desire to provide improved assemblies, apparatuses, systems, and methods for extracting material from a source and/or depositing material at a desired location, including a variety of different materials from a variety of different environments, that may be more practicable, more efficient, less time consuming, and/or less labor intensive. The present disclosure may address one or more of the above-referenced drawbacks, as well as other possible drawbacks.
As referenced above, it may be desirable to provide enhanced assemblies, apparatuses, systems, and methods for extracting material from a source of the material and/or depositing the material at a desired location, including a variety of different materials from a variety of different environments, that may be more practicable, more efficient, less time consuming, and/or less labor intensive. For example, the intentional generation or production of some materials for desired intermediate or final products may result in the deposit or accumulation of by-product materials that need to be removed from the environment in which the desired products are generated or produced. In some embodiments, the assemblies, apparatuses, systems, and methods may provide enhanced extraction of material to be removed from various environments, such as, for example, work sites, industrial sites, commercial sites, residential sites, natural sites, etc. For example, in some embodiments, the material may be extracted in a substantially continuous manner and/or may be extracted without significant contamination of the ambient environment with the material or portions thereof. In some embodiments, the assemblies, apparatuses, systems, and methods may provide enhanced conveyance for the efficient delivery of material to be loaded and/or deposited in various environments and/or sites.
In some embodiments, a method to enhance extraction of pall rings from a refinery apparatus may include supplying a pressurized fluid to a plurality of vacuum generators, and generating, using the pressurized fluid, a vacuum flow.

The method also may include extracting pall rings from the refinery apparatus via the vacuum flow through the manifold to a material collector through which the vacuum flow passes, depositing at least a portion of the extracted pall rings in the material collector. The method further may include passing the vacuum flow into a sound attenuation chamber to reduce a sound level generated by one or more of the vacuum flow or generating the vacuum flow.
In some embodiments, a material extraction assembly to enhance extraction of pall rings from a refinery apparatus may include a vacuum source including a plurality of vacuum generators.

In some embodiments, a method to enhance conveyance of pall rings from a pall ring source to a material discharge outlet providing fluid communication to a refinery apparatus, the material discharge outlet being located at an elevated position relative to the pall ring source, may include supplying a pressurized fluid to a plurality of vacuum generators, and generating, using the pressurized fluid, a vacuum flow. The method further may include associating a conveyance manifold with the pall ring source. The conveyance manifold may provide a flow path for the vacuum flow between the pall ring source and the material discharge outlet. The method also may include conveying pall rings from the pall ring source via the vacuum flow through the conveyance manifold to the material discharge outlet, depositing at least a portion of the pall rings in the refinery apparatus. The method further may include passing the vacuum flow into a sound attenuation chamber to reduce a sound level generated by one or more of the vacuum flow or generating the vacuum flow.

The accompanying drawings, which are included to provide a further understanding of the embodiments of the present disclosure, are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure, and together with the detailed description, serve to explain principles of the embodiments discussed herein. No attempt is made to show structural details of this disclosure in more detail than may be necessary for a fundamental understanding of the embodiments discussed herein and the various ways in which they may be practiced. According to common practice, the various features of the drawings discussed below are not necessarily drawn to scale. Dimensions of various features and elements in the drawings may be expanded or reduced to more clearly illustrate embodiments of the disclosure.
The drawings include like numerals to indicate like parts throughout the several views, the following description is provided as an enabling teaching of exemplary embodiments, and those skilled in the relevant art will recognize that many changes may be made to the embodiments described. It also will be apparent that some of the desired benefits of the embodiments described may be obtained by selecting some of the features of the embodiments without utilizing other features. Accordingly, those skilled in the art will recognize that many modifications and adaptations to the embodiments described are possible and may even be desirable in certain circumstances. Thus, the following description is provided as illustrative of the principles of the embodiments and not in limitation thereof.
The phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. As used herein, the term “plurality” refers to two or more items or components. The terms “comprising,” “including,” “carrying,” “having,” “containing,” and “involving,” whether in the written description or the claims and the like, are open-ended terms, in particular, to mean “including but not limited to,” unless otherwise stated. Thus, the use of such terms is meant to encompass the items listed thereafter, and equivalents thereof, as well as additional items. The transitional phrases “consisting of” and “consisting essentially of,” are closed or semi-closed transitional phrases, respectively, with respect to any claims. Use of ordinal terms such as “first,” “second,” “third,” and the like in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one claim element having a certain name from another element having a same name (but for use of the ordinal term) to distinguish claim elements.
For example, some types of chemical reactions may utilize a catalyst material to mediate the chemical reactions, for example, by causing the reaction to occur and/or increasing/decreasing a rate at which the reaction occurs, etc. In a chemical reaction tower (see, e.g.,
In another example, some types of chemical reactions may utilize devices and/or materials to facilitate the chemical reactions. For example, a packing material may increase the surface area and number of edge surfaces over which the reaction occurs to improve reaction efficiency and/or to increase/decrease a rate at which the reaction occurs, etc. In a chemical reaction tower (see, e.g.,
The chemical reaction may also interact with the materials out of which the chemical reaction tower is formed. For example, some chemical reaction towers may be formed from concrete and steel. Chemical reaction towers may be formed from any number and types of materials. The catalyst or the other materials in the chemical reaction tower may react or otherwise interact with these materials of the chemical reaction tower, forming additional undesired products, which may be referred to as “tower products.”
The undesired reaction products and/or the tower products, which may be referred to as “waste material,” may move within the chemical reaction tower. For example, some of this material may partially or completely cover the catalyst or other important features of the chemical reaction tower, thereby reducing the effectiveness of the catalyst, for example, even in cases where the catalyst is not depleted but remains active.
In some examples, the undesired reaction products and/or the tower products, the “waste material,” may partially or completely cover the packing material (e.g., the pall rings) or other important features of the chemical reaction tower, thereby reducing the effectiveness of the packing material. This accumulation may inhibit the reactions of the chemical reaction tower, for example, even in instances where the packing material itself is not depleted or damaged.
The presence of the depleted catalyst material, catalyst or packing material covered in waste material, and/or the waste material itself, may impair future functioning of the chemical reaction tower. For example, the presence of this material in the chemical reaction tower may reduce the conversion efficiency (e.g., the quantity of desirable products produced versus the quantity of input products) of the chemical reactions, increase a reaction time, may render the chemical reactions more difficult to control (or prevent them from occurring), and/or may otherwise reduce the ability of the chemical reaction tower to perform its intended function.
Some embodiments disclosed herein may relate to assemblies, apparatuses, systems, and methods for extracting material from a source of the materials, such as, for example, removing undesired material from environments, such as, for example, industrial environments. In some embodiments, the extracted material may include one or more of pall rings, beads, balls, pellets, sand, or bricks. Embodiments may also relate to assemblies, apparatuses, systems, and methods for conveying and depositing new and/or recycled material from a source of the material. In some embodiments, the conveyed or deposited material may include one or more of pall rings, beads, balls, pellets, sand, or bricks. For example, some embodiments disclosed herein may facilitate extraction of undesired materials or deposition of new and/or recycled material from or to an industrial environment using, for example, a high-pressure vacuum flow. Removing undesired material from an industrial environment using a high-pressure vacuum flow may provide for time-efficient removal of the undesired materials and/or may reduce or prevent contamination of the ambient environment with the undesired material or portions thereof. Similarly, depositing new and/or recycled materials, such as packing material, using a high-pressure vacuum flow may provide for time-efficient replacement of said materials in the industrial environment.
Industrial environments, chemical reaction towers, and the associated material discussed herein are merely examples, and other types of environments and/or other types of materials are contemplated.
As schematically depicted in
For example, as shown in
In some embodiments, the material extraction assembly 10 may be configured to efficiently extract the undesired material 16 through the reaction vessel ports 24, for example, by generating a high-pressure vacuum flow and associating the high-pressure vacuum flow to external portions of respective reaction vessel ports 24. In some embodiments, the high-pressure vacuum flow may generate suction directed out of the interior of reaction vessel 14 through the respective reaction vessel ports 24. The suction may generate a vacuum induced vacuum flow 26 with at least a portion of the undesired material 16 entrained in the vacuum induced vacuum flow 26.
Depending on, for example, the distribution of the undesired material 16, various fixtures may be attached to the reaction vessel ports 24 to control application of suction to the undesired material 16. In some embodiments, conduits, such as hoses or other fluid flow directing carriers may be pneumatically connected to one or more of the reaction vessel ports 24, for example, inside of the reaction vessel 14. The conduits may be positioned such that the vacuum flow 26 entrains desired quantities of the undesired material 16 in the vacuum flow 26. Exterior portions of the reaction vessel ports 24 may be connected to other components of the material extraction assembly 10, for example, to apply the high-pressure vacuum and/or process undesired material 16 entrained in the vacuum flow 26.
In some instances, at least a portion of zones 18 of the reaction vessel 14 may not be reasonably accessible via one or more of the reaction vessel ports 24, and some undesired material 16 may be present in such zones. In some embodiments, one or more of the zones 18 of the reaction vessel 14 may include substantially sealed zones. Such sealed zones may not be readily accessible via one or more of the reaction vessel ports 24 or other structures through which fluid flow paths may be established from the interior of the reaction vessel 14 to outside the reaction vessel 14. In some embodiments, to remove undesired material 16 from a sealed zone, a temporary access port may be formed in the reaction vessel 14. The temporary access port may be drilled or cut through the shell of the reaction vessel 14 to facilitate access to the sealed zone from outside the reaction vessel 14. The temporary access port may facilitate access to the sealed zone 28 from outside of reaction vessel 14.
Applicant has recognized that the undesired material may present a contamination threat to areas near reaction vessels. The undesired material 16 may include significant quantities of small particles that may be difficult to control. In some embodiments, the material extraction assembly 10 may facilitate extraction of undesired material with an at least partially sealed system. For example, the at least partially sealed system may be configured to transfer the undesired material from the reaction vessel 14 using a substantially sealed fluid flow path having a limited number of potential exit points. In some embodiments, the flow path may be filtered prior to exiting the flow path to limit or prevent discharge of particulate forms of the undesired material from at least some embodiments of the material extraction assembly 10.
Applicant has recognized that the undesired material 16 may be heterogeneous in nature and/or may include material that ranges in size from particulates to one or more inches in size. The undesired material 16 may also be in various states of matter. For example, some portions of the undesired material 16 may be solid, and other portions may be liquid or semi-liquid. Conventional approaches to material removal may be unable to effectively process heterogeneous undesired materials. In some embodiments, the material extraction assembly 10 may facilitate extraction of heterogeneous undesired material, for example, using the high-pressure vacuum flow 26. In some embodiments, the high-pressure vacuum flow 26 may be capable of moving a broad range of materials in various states of matter. The use of a high-pressure vacuum flow 26 for material extraction may facilitate substantial containment of removed undesired material 16, thereby limiting or preventing release into or contamination of the ambient environment with portion of the extracted undesired material 16.
The example material extraction assembly 10 shown in
As shown in
In some embodiments, one or more of the material collector 36, the vacuum source 38, or the sound attenuation chamber 40 may be arranged to form a flow path beginning at the source of the material (e.g., at the reaction vessel 14) and terminating at the sound attenuation chamber 40. The flow path may be used to extract undesired material 16 from the reaction vessel 14 and, in some embodiments, limit contamination of the ambient environment. For example, the vacuum source 38 may generate a vacuum in the flow path, thereby generating a fluid flow along the flow path. The fluid flow may be used to apply suction proximate the undesired material 16 in the reaction vessel 14 to draw the undesired material 16 into the flow path. The fluid flow in the flow path may cause the undesired material 16 to flow out of reaction vessel 14 and into material collector 36, thereby separating at least a portion of the undesired material 16 from the environment. In some embodiments, a major portion of the undesired material 16 may be deposited in the material collector 36. In some embodiments, a minor portion of the undesired material 16 may flow from the material collector 36, through the vacuum source 38, and into the sound attenuation chamber 40. In some embodiments, the sound attenuation chamber 40 may be configured to remove (or reduce) the minor portion of the undesired material 16 in the fluid flow prior to the fluid flow being exhausted into the ambient environment.
In some embodiments, to form the flow path, the material collector 36 may be pneumatically connected to the source of the undesired material (e.g., the reaction vessel 14). In some embodiments, the pneumatic connection between reaction vessel 14 may be formed using a manifold 44. The manifold 44 may be connected to multiple reaction vessel ports 24 of the reaction vessel 14, thereby pneumatically connecting the material collector 36 to multiple locations of the reaction vessel 14. For example, the interior of the material collector 36 may be pneumatically connected to the reaction vessel 14. Pneumatically connecting the material collector 36 to multiple locations of reaction vessel 14 may facilitate extraction of undesired material 16 from each of the locations, for example, concurrently, simultaneously, sequentially, in parallel, etc.
Some reaction vessels 14 may be tall. Due to the height of some reaction vessels 14 and the distribution of the zones along the height, it may be challenging to access one or more of the zones of the reaction vessel 14. In some embodiments, the manifold 44 may include relatively rigid piping (e.g., poly pipe or polyethylene pipe). The piping may render the manifold 44 at least partially self-supporting, which may facilitate pneumatic connection of the manifold 44 to multiple zones of the reaction vessel 14. The manifold 44, in some embodiments, may pneumatically connect the material collector 36 to any number of locations on the reaction vessel 14, for example, such as those that are difficult to reach or access. The piping may be of low weight and/or easily attachable to a wide variety of structures, which may reduce the need for significant in-person access to difficult-to-reach locations on/in the reaction vessel 14 to extract undesired material 16.
In some embodiments, the manifold 44 may be pneumatically connected to the material collector 36, for example, via a conduit 46, such as a hose. In some embodiments, the conduit 46 may be flexible to allow for pneumatic connection of the manifold 44 and the material collector 36 in various orientations and positions with respect to one another. The conduit 46 may be sized so as not to limit the flow of fluid along the flow path.
In some instances, the undesired material 16 in the reaction vessel 14 may present a clogging potential. For example, the undesired material 16 may include relatively large components that may tend to wedge or catch on structures through which the undesired material 16 is drawn. In some embodiments, the conduit 46 may be, at least in part, transparent, translucent, and/or capable of providing an indication of the contents passing through the conduit 46, which may be usable to detect and/or diagnose whether the conduit 46 is clogging. As noted herein, the undesired material 16 may be heterogeneous and may include relatively large components that may tend to clog narrow passages (e.g., constrictions in the conduit 46). To reduce the risk of clogging, in some embodiments, the conduit 46 may include, at least in part, a smooth inner surface, such as may be present in poly pipe. A smooth inner surface may reduce the risk of, or prevent, clogging of the conduit 46.
Although the example suction manifold 44 is shown in
In some embodiments, the undesired material 16 may flow into the material collector 36 after flowing through the manifold 44. A major portion of the undesired material 16 may be collected in the material collector 36. In some embodiments, however, some (e.g., a minor portion) of the undesired material 16 may flow out of the material collector 36 in the flow path of the high-pressure vacuum flow 26. In some embodiments, the material collector 36 may remove a major portion of the undesired material 16 from the fluid flow it receives along the flow path of the vacuum flow 26. In some embodiments, the material collector 36 may receive all, or a portion, of the fluid flow out of the reaction vessel 14, and the material collector 36 may include one or more structures configured to trap a major portion of the undesired material 16 in the fluid flow received inside the material collector 36. Once trapped, the major portion of the undesired material 16 may be retained in the material collector 36, for example, for disposal, recycling, and/or remediation.
Applicant has recognized that it may be desirable to rapidly convey materials in large quantities and/or in an efficient manner to desired locations, for example, that may present unique challenges. For example, it may be difficult to rapidly convey large quantities of materials to an elevated position relative to a source or supply of the material. Although liquid materials may be pumped to elevated positions using conventional pumps, other types of materials, such as semi-solid materials, sludge, particulates, sand, gravel, and discrete solid materials of regular or irregular sizes and shapes may be difficult efficiently to convey to elevated locations.
For example, environments similar to the example environment illustrated in
In some embodiment, the material conveyance assembly 11 shown in
The example reaction vessel 14 may be a refinery apparatus including a tower separated internally into various zones 18. The material source 39 may be, for example, a desired source of new, cleaned, regenerated, and/or recycled material, such as pall rings, and the pall rings may include and/or be formed from one or more of metal, ceramic, or polymeric materials. The pall rings may have one or more of any known pall ring sizes, configurations, and/or geometries. In some examples, the desired material 16 from the material source 39 may be new and/or regenerated catalyst or similar materials.
To provide for the rapid conveyance and/or deployment of desired material 16, in some embodiments, the material conveyance assembly 11 may include a separator housing 45. The separator housing 45 may be a device configured to rapidly convey and deploy desired materials 16 into an interior of the reaction vessel 14. For example, the separator housing 45 may be positioned at an elevated location relative to the material source 39, for example, toward an upper portion of the reaction vessel 14, and may receive the desired material 16. The separator housing 45, upon receipt of the desired material 16, may separate the desired material 16 from the high pressure vacuum flow 26, in which the desired material 16 is entrained and conveyed from the material source 39, and in which is used to carry the desired material 16 through the conveyance manifold 41 to the separator housing 45. The high pressure vacuum flow 26 may be directed to the separator housing 45 with the conveyance manifold 41.
In some embodiments, desired material 16 received in the separator housing 45 may be pumped, gravity fed, and/or otherwise directed through the material discharge outlet 43 into the interior of the reaction vessel 14. In some embodiments, the material discharge outlet 43 may be pneumatically connected to the reaction vessel 14 and located at an elevated position relative to the material source 39. The pneumatic connection between the material discharge outlet 43 and the reaction vessel 14 may be, for example, a conveyance chute 49. The conveyance chute 49 may extend at least partially into the interior of the reaction vessel 14 to facilitate the delivery of the conveyed material 16. In some embodiments, the conveyance chute 49 may include one or more flexible tubular members or other similar devices. The material discharge outlet 43 may be connected to the conveyance manifold 41 and the suction manifold 44 via the separator housing 45. The separator housing 45 may be, for example, situated above the material discharge outlet 43 and the reaction vessel 14, and may be provided with a diverter 47 or other structure capable of allowing the vacuum flow 26 to pass therethrough while directing conveyance of the desired material 16 toward the material discharge outlet 43 for deposit and/or distribution within the reaction vessel 14. The diverter 47 may include, for example, a porous element (e.g., a screen and/or filter media), a valve, and/or any device or devices capable of separating at least a majority of the desired material 16 from the vacuum flow 26 in the separator housing 45.
Although the example conveyance manifold 41 and suction manifold 44 are shown in
Although gravity, pumping, and/or other methods may be employed to clear the separator housing 45 and material discharge port 43 of blockages of the desired material 16 conveyed by the material conveyance assembly 11 to the reaction vessel 14, there may be a desire to dislodge any material 16 collected in and around the material discharge port 43. In some embodiments, desired material 16 (e.g., new and/or recycled pall rings, catalyst, etc.) that has accumulated in and around the discharge port 43 and which has not been deposited into the interior of the reaction vessel 14 may be dislodged by, for example, vibrating one or more of the components. For example, a vibration assembly 51 may be attached to the separator housing 47 and/or conveyance chute 49 adjacent to the passage near the top of the reaction vessel 14. The vibration assembly 51 may be used to induce dynamic vibration in one or more of the surrounding separator housing 47, the conveyance chute 49, or the suction manifold 44, for example, to dislodge accumulated material and deposit the accumulated material into the interior of the reaction vessel 14.
In some embodiments, the suction manifold 44 may be pneumatically connected to the vacuum source 38, for example, via a conduit 46, such as a hose. In some embodiments, the conduit 46 may be flexible to allow for pneumatic connection of the suction manifold 44 and the vacuum source 38 in various orientations and positions with respect to one another. The conduit 46 may be sized so as not to limit the flow of fluid along the flow path.
In some embodiments, as shown in
For example, the ports may include an inlet port 54, a vacuum port 56, and a discharge port 58. The inlet port 54 may be positioned on the housing 50 and configured to allow access to the interior 52 from outside the housing 50. The inlet port 54 may include an aperture through a wall of the housing 50 that facilitates pneumatic connection of the interior 52 to other components of the material extraction assembly 10. In some embodiments, the inlet port 54 may be pneumatically connected to the suction manifold 44 (
As shown in
Applicant has recognized that for applications when undesired material 16 is being extracted from the reaction vessel 14, the vacuum box 48 may be able to store only a limited quantity of material and that the amount of the limited quantity may depend, for example, on how the material is distributed in the interior 52 of the housing 50. For example, if material is deposited in the interior 52 near locations where fluid flow may exit the interior 52, significant quantities of the material in the interior 52 may be drawn out of the interior 52 rather than being retained in the vacuum box 48. The reaction vessel 14 (or other sources of material to be extracted) may include a greater volume of material than the vacuum box 48 is able to hold.
In some embodiments, the vacuum box 48 may be configured to facilitate distribution of material within (e.g., throughout) the interior 52 of the vacuum box 48. Distributing the material in the interior 52 may increase the amount of material that may be retained in the interior 52 without increasing the rate at which the material exits vacuum box 48 due to fluid flow through the interior 52 of the vacuum box 48. This may result in the vacuum box 48 having an increased effective material capacity (e.g., the maximum material capacity at which the quantity of material exiting a structure passes a threshold level) as compared to other structures that do not distribute material throughout their respective interiors. The increased effective material capacity of some embodiments of the vacuum box 48 may reduce the rate at which the vacuum box 48 may need to be replaced as a result of being full due to the use of high-pressure vacuum flow 26 for material extraction. In some embodiments, the vacuum box 48 may facilitate time-efficient replacement in a material extraction assembly, so as to enable the material extraction system to substantially continuously remove undesired material 16 using multiple vacuum boxes 48.
As shown in
In some embodiments, the vacuum port 56 may be positioned on the housing 50 to facilitate access to the interior 52 from outside the housing 50, for example, to facilitate the high-pressure vacuum flow 26 to be applied to the interior 52 of the housing 50. The vacuum port 56 may include an aperture passing through a wall of the housing 50 and may allow for the interior 52 to be pneumatically connected to other components of the material extraction assembly 10. In some embodiments, the vacuum port 56 may be pneumatically connected to the vacuum source 38 to enable the vacuum source 38 to apply a vacuum to the interior 52 of the housing 50. The one or more conduits 70 and/or other fluid flow components may form a flow path from the interior 52 to various locations outside the housing 50. In some embodiments, the one or more conduits 70 may be connected at a location where the vacuum port 56 passes through a wall of the housing 50 to a location more easily accessible to a person to make pneumatic connections between the vacuum port 56 and other components of the material extraction assembly 10. For example, as shown in
In some embodiments, the interior 52 may be placed along the flow path through which the undesired material 16 flows. In some embodiments, the inlet port 54 and the vacuum port 56 may be positioned with respect to the interior 52 of the housing 50 to establish a flow path into and out of the interior 52 of the housing 50. The flow path may cause fluid flow directed into the inlet port 54 to flow through the interior 52 and out the vacuum port 56. The flow path through the interior 52 may be placed along the flow path through the material extraction assembly 10. The flow path may be used in combination with other flow paths, for example, flow paths parallel to one another, to enhance the rate at which undesired material may be removed, to enhance the strength of the applied high-pressure vacuum flow 26 to facilitate removal of materials presenting a challenge to extraction (e.g., materials having a higher viscosity, materials including significant solid content, etc.), or for other purposes, for example, as shown in
In some embodiments, the vacuum box 48 may be configured to move the undesired material 16 in the interior 52 to reduce the likelihood of it flowing out the vacuum port 56, which may improve the capacity of the vacuum box 48. For example, the vacuum box 48 may include a material mover 72 configured to move the undesired material 16 within the interior 52, for example, as shown in
In some embodiments, the auger 74 may be positioned in the interior 52 to distribute the undesired material 16 within the interior 52. The auger 74 may include a drill, one or more helical flights, and/or other structures for applying force to the undesired material 16 in the interior 52 of the housing 50. For example, when the auger 74 rotates, a drill or helical flights of the auger 74 may apply force to the undesired material 16 to move it within the interior 52. The movement caused by auger 74 may more evenly distribute the undesired material 16 within the interior 52, for example, to reduce the likelihood of the undesired material 16 flowing out the exhaust port 56. The drive unit 76 may include a motor or other type of actuator usable to rotate the auger 74 by application of a rotational force. In some embodiments, the drive unit 76 may include a hydraulic motor driven using electric power. The quantity of electric power required to rotate auger 74 by the drive unit 76 may be directly related to the quantity of undesired material 16 in the interior 52. For example, as the quantity of undesired material 16 in the interior 52 increases, it may require progressively larger amounts of electric power for the drive unit 76 to rotate the auger 74. As a result, the quantity of electrical power used by the drive unit 76 may be used to determine the load on the auger 74 and/or the quantity of the undesired material 16 in the interior 52 of the housing 50.
To manage the operation of auger 74, in some embodiments, the drive unit 76 may be operably connected to a drive controller 78, which may be coupled to system level controllers. The drive controller 78 may direct, instruct, or otherwise orchestrate operation of the drive unit 76. The drive controller 78 may include computing hardware (e.g., processors, memory, storage devices, communication devices, other types of hardware devices including circuitry, etc.) and/or computing instructions (e.g., computer code) that when executed by the computing hardware cause the drive controller 78 to provide its functionality.
In some embodiments, the drive controller 78 may utilize its computing hardware to set an operating point 77 for the drive unit 76. For example,
To set the operating point 77 of the drive unit 76, in some embodiments, the drive controller 78 may obtain information from one or more sensors 80. For example, the one or more sensors 80 may be positioned at various locations on/in the housing 50 (and/or other locations) and may be operably connected to the drive controller 78 (e.g., in communication with the drive controller 78). The one or more sensors 80 may be configured to generate signals indicative of one or more physical properties, communicating the signals to the drive controller 78, and/or displaying information relating to the physical properties (or quantities determined from the measured physical properties, such as, for example, the fill level 79 of the vacuum box 48). The drive controller 78 may include a data structure (e.g., a table, list, function, etc.) usable to estimate the fill level 79 of the vacuum box 48 based at least in part on the physical properties measured with the one or more sensors 80. The data structure may include a lookup table that provides the fill level 79 of the vacuum box 48 as a function of the measured physical properties. The measured physical properties may include, for example, temperatures, depths/heights of material in the interior 52, opacities of the material, quantities of light reflected by or transmitted through the material, etc.
To measure temperatures, in some embodiments, the vacuum box 48 may include one or more sensors such as thermocouples or other devices for measuring temperature. The one or more sensors 80 may be positioned to measure the temperature of the housing 50, the interior 52, or other components of the vacuum box 48. In some embodiments, the data structure may provide the fill level 79 of the vacuum box 48 as a function of, for example, the temperature of one or more portions of the vacuum box 48.
To measure depths or heights of the undesired material in the vacuum box 48, in some embodiments, the vacuum box 48 may include one or more sensors 80 including depth sensors, such as float sensors, interferometers, etc. The depth sensors may be positioned in the interior 52, on the housing 50, and/or in other locations to measure the height of the undesired material 16 in the vacuum box 48. In some embodiments, the data structure may provide the fill level 79 of the vacuum box 48 as a function of, for example, the heights of the undesired material 16 in the vacuum box 48.
To measure available light, in some embodiments, the vacuum box 48 may include one or more sensors 80 that include photo-sensors (e.g., charge-coupled devices, etc.). The photo-sensors may be positioned to measure the intensity of light reflected by or transmitted by the undesired material 16 in the interior 52 (or other visual indicators), so as to determine the fill level 79 of the vacuum box 48. In some embodiments, the data structure may provide the fill level 79 of the vacuum box 48 as a function of, for example, the measured light intensity of the undesired material 16 in vacuum box 48.
To determine the fill level 79 of the vacuum box 48, in some embodiments, the drive controller 78 receives sensor signals from the one or more sensors 80 using one or more wireless or wired connections. The drive controller 78 may provide the measurements and/or the load on the drive unit 76 to system level controllers (e.g., supervisory controller(s)) using the one or more wireless or wired connections. The drive controller 78 may use the measurements to determine the fill level 79 of the vacuum box 48 using the data structures. Based on the determined fill level 79 and/or a state of the system (e.g., provided by system supervisory controller(s) 81), the drive controller 78 may determine an operating point 77 for the drive unit 76. The drive unit 76 may consume electric power based on the operating point 77, thereby enabling the drive controller 78 to control the rate at which undesired material 16 is moved within the vacuum box 48.
In some embodiments, the vacuum box 48 may include a floor 68 having a V-shaped cross-section or other features. Such a floor 68 or other features may tend to make the housing 50 tip to one side or the other side if the housing 50 is placed directly onto a planar surface. To orient the vacuum box 48, in some embodiments, the vacuum box 48 may be provided with a carrier 84, for example, as shown in
Once the vacuum box 48 is filled with material, it may need to be unloaded before it may continue to be used. For example, extracted material 16 may include spent catalyst and/or used pall rings which may be effectively cleaned or recycled. To facilitate rapid unloading of the vacuum box 48, in some embodiments, the vacuum box 48 may include a door 92 (
In some embodiments, the vacuum generation and sound attenuation assembly 12 may include a vacuum source 38, which may be pneumatically connected to the material collector 36 by a conduit 96 (e.g., a hose). The pneumatic connection may allow the vacuum source 38 to apply a high-pressure vacuum flow 26 to the material collector 36. For example, the vacuum flow 26 may be applied to the interior 52 of the material collector 36 via the conduit 96 (or through other types of pneumatic connections between the components). The applied vacuum flow 26 may generate the vacuum induced fluid flow 26 along the flow path, thereby conveying the undesired material 16 from reaction vessel 14 to material collector 36.
In some embodiments, the vacuum generation and sound attenuation assembly 12 may include a vacuum source 38, which may be pneumatically connected to the suction manifold 44 by a conduit 96 (e.g., a hose). The pneumatic connection may allow the vacuum source 38 to apply a high-pressure vacuum flow 26 to the suction manifold 44. For example, the vacuum flow 26 may be applied to the suction manifold 44 and transmitted through the conveyance manifold 41 to draw material from the material source 39. The applied vacuum flow 26 may generate the vacuum induced fluid flow 26 along the flow path between the conveyance manifold 41 and the suction manifold 44 (see arrows in
As shown in
In some embodiments, the vacuum source 38 may be implemented using a variety of configurations, depending, for example, on the environment to which the material collector 36 is deployed for operation. For example, in some embodiments, as shown in
The one or more vacuum generators 106 may be configured to generate the vacuum flow 26 in different ways, depending at least in part on, for example, the environment to which the vacuum and attenuation module 100 is deployed. For example, in some embodiments, the vacuum generators 106 may be configured to generate the vacuum flow 26 using the flow of another fluid. For example, the vacuum generators 106 may be connected to a fluid source 42 (see
When the one or more vacuum generators 106 generate the vacuum flow 26, in some embodiments, the vacuum generators 106 may combine vacuum-induced flow 26 and a fluid supply flow 108, and exhaust the combined flows as a vacuum exhaust fluid flow 110, which may include the minor portion of the undesired material 16, for example, as schematically shown in
In some embodiments, in order to generate a more powerful high-pressure vacuum flow 26, multiple vacuum sources 38 and/or one or more sound attenuation chambers 40 may be positioned on a common chassis 102 to form a more powerful vacuum generation and sound attenuation assembly 12 (e.g., a more powerful unified vacuum and attenuation module 100). For example, multiple vacuum sources 38 may each be pneumatically connected to the (one or more) sound attenuation chambers 40, which may cause two (or more) separate flow paths (e.g., for each of the vacuum sources 38) and which may be combined at the one or more sound attenuation chambers 40. In some embodiments, the vacuum sources 38 may be pneumatically connected to a common material collector 36 (e.g., to increase the strength of the high-pressure vacuum flow 26 through the common material collector 36) or different material collectors 36 (e.g., to enable the undesired material 16 to be transferred to multiple material collectors 36 in parallel). In some embodiments, the vacuum sources 38 may be pneumatically connected to the suction manifold 44 (e.g., to increase the strength of the high-pressure vacuum flow 26 through the suction manifold 44) or to multiple inlets in parallel on the suction manifold 44.
In some embodiments, the vacuum source 38 may be implemented using a variety of different structures, depending at least in part on, for example, the environment to which vacuum source 38 is deployed. For example, in some embodiments, the vacuum source 38 may include one or more vacuum generators 106, each having a venturi mechanism 114 configured to receive pressurized fluid from the fluid source 42 (see
As schematically depicted in
In some embodiments, to generate the vacuum flow 26, the fluid supply ports 116 are pneumatically connected to the fluid source 42, which may be a mobile fluid supply. For example, the fluid supply ports 116 may be pneumatically connected to a compressed fluid stored at or in the fluid source 42. The compressed fluid may be used to generate the fluid supply flow 108 from the fluid source 42. The fluid supply flow 108 may be received through the pneumatic connection and into the fluid supply ports 116. The fluid supply flow 108 may be configured to drive the venturi mechanism 114, thereby generating the vacuum flow 26 produced by the vacuum source 38, which may be applied to other devices via the vacuum port 118.
The strength of the vacuum flow 26 generated by the venturi mechanism 114 may depend at least in part on, for example, the rate of the fluid supply flow 108 used to drive the venturi mechanism 114. In order to achieve higher vacuum pressure generation, in some embodiments, the vacuum source 38 may include a combiner 122. The combiner 122 may include a manifold for combining multiple fluid supply flows 108 received by the fluid supply ports 116 into a single fluid flow and directing the single fluid flow into the venturi mechanism 114 for generating the vacuum flow 26.
In some embodiments, to manage or control the flow rate, pressure, and/or volume of the fluid supply flow 108 into the venturi mechanism 114, which may be used to control or regulate the strength of the vacuum flow 26, fluid flow control valves 124 may be positioned between the fluid supply ports 116 and the fluid source 42. In some embodiments, the strength of the vacuum flow 26 generated by the venturi mechanism 114 may be substantially proportional to the flow rate, pressure, and/or volume of fluid flow into the fluid supply ports 116. The fluid flow control valves 124 may be used to limit (e.g., reduce, stop, etc.) the rate of fluid flow into the venturi mechanism 114 from the fluid supply ports 116.
In some embodiments, the vacuum port 118 may be pneumatically connected to the one or more material collectors 36 and/or the suction manifold 44 to apply a vacuum to the one or more material collectors 36 and/or suction manifold 44. Applying the vacuum may generate the vacuum-induced fluid flow 26 into the vacuum port 118. When connected to one or more material collectors 36, the vacuum-induced fluid flow 26 may draw material 16 into the one or more material collectors 36 from the source of the material (e.g., the reaction vessel 14). A major portion of the material 16 may be trapped by and within the material collector 36, and a minor portion of the material 16 may flow into the vacuum source 38 in vacuum-induced fluid flow 26.
To prevent or limit contamination of the ambient environment by a portion of any undesired material 16, in some embodiments, the exhaust port 120 may be pneumatically connected to the sound attenuation chamber 40. For example, the exhaust port 120 may be pneumatically connected to the sound attenuation chamber 40, which may exhaust the vacuum-induced fluid flow 26, which may include the minor portion of the undesired material 16, and the fluid supply flow 108, for example, as a combined fluid flow into the sound attenuation chamber 40.
In some embodiments, the pneumatic connections between the ports 116, 118, and/or 120 of the vacuum source 38 may be made using conduits, such as hoses or other flexible tubular structures. The conduits may enable the pneumatic connections to be efficiently made, thereby reducing the setup time for assembling the material extraction assembly 10, for example, shown in
Applicant has recognized that the use of conduits, such as hoses or other flexible tubular structures may present a potential hazard to a person near the conduits. For example, the vacuum flow 26 generated by the vacuum source 38 may cause the conduits to flex or move due to the forces applied to them by the fluid flows. A person may be impacted by the conduits if the flexing or movement of the conduits is significant and/or unexpected. In some embodiments, the material extraction assembly 10 or material conveyance assembly 11 may reduce or eliminate one of more of the conduits, for example, by pneumatically connecting one or more of the components of the material extraction assembly 10 or material conveyance assembly 11 to one another in a manner that eliminates a need for at least some of the conduits (e.g., connecting components directly to one another). For example, the material extraction assembly 10 or material conveyance assembly 11, in some embodiments, may include direct attachment of the vacuum source 38 to one or more material collectors 36, the suction manifold 44, and/or to the sound attenuation chamber 40. By directly attaching the vacuum source 38 to the one or more material collectors 36, the suction manifold 44, and/or the sound attenuation chamber 40, conduits, additional hoses or other flexible structures may not be necessary. As a result, the potential hazard of impact by uncontrolled movement by the conduits or other flexible structures to a person may be reduced or eliminated.
As shown in
Applicant has recognized that the material 16 may, in some instances, be challenging to move via fluid flow by virtue of, for example, the state of matter of the material 16, the weight of the material 16, the viscosity and/or surface tension of the material 16, and/or other physical properties of the material 16. Such characteristics of the material 16 may limit the rate at which the material 16 may flow through the fluid flow path if only a limited level of the vacuum flow 26 is generated by the vacuum generators 106. In some embodiments, the material extraction assembly 10 or material conveyance assembly 11 may be configured to provide a high-pressure vacuum flow 26, which may be suitable to expedite flow of the material 16 through the fluid flow path. To expedite the flow of the material 16, the vacuum source 38, in some embodiments, may include two or more vacuum generators 106, such as two or more venturi mechanisms 114, which may be operated in parallel with each other in order to enhance the pressure of the vacuum flow 26 generated by the vacuum source 38. Each of the two or more vacuum generators 106 may be driven using the pressurized fluid from the fluid source 42 (and/or other sources of pressurized fluid, such as other fluid sources (e.g., mobile fluid supplies)).
In some embodiments, to manage the pressure generated by vacuum source 38, the venturi mechanisms 114 maybe divided into two dual vacuum sources 126. Each of the venturi mechanisms 114 of the two dual vacuum sources 126 may be fluidly connected in parallel to each other, for example, so that they each may be driven using a common fluid supply port 116, may commonly exhaust out of a common exhaust port 120, and/or may apply vacuum using a common vacuum port 118. In this example manner, each dual vacuum source 126 may provide a higher pressure vacuum flow 26 than may be provided using a single venturi mechanism 114 driven by a similar rate of fluid flow received from the fluid source 42.
A plurality of vacuum conduits 121 may be provided with the vacuum source 38 to provide a flow path between one or more of the vacuum sources 126 and the sound attenuation chamber 40. The vacuum conduits 121 may be, for example, ducts of flexible steel conduits, such as flexible corrugated steel conduits. The vacuum conduits 121 may be capable of absorbing reaction loads at the joints with the vacuum sources 126 and/or the sound attenuation chamber 40, for example, while resisting collapse under the negative pressures of the vacuum flows 26 from the venturi mechanisms 114 of the vacuum sources 126.
To control the generation of the vacuum flow 26 by the one or more vacuum sources 38, in some embodiments, the ports 116, 118, and/or 120 of each dual vacuum source 126 may be controlled by corresponding respective control valves 128, 130. The control valves 128, 130, may be usable to control the rate of fluid flow through each of the respective ports.
In some embodiments, to manage the process of generating the high-pressure vacuum flow 26, the vacuum source 38 may include a vacuum source controller 136. The vacuum source controller 136 may be in communication with one or more of the control valves 128, 130. The vacuum source controller 136 may be configured to control operation of one or more of the control valves 128, 130 to provide vacuum flows having desired pressures. For example, the vacuum source controller 136 may be operably coupled to an adjustor, such as a switch, dial, or other mechanism that a person may operate to achieve a desired level of vacuum pressure to be generated by the vacuum source 38. The vacuum source controller 136 may use one or more signals from the adjustor to set the operation points for the one or more control valves 128, 130 to generate the desired vacuum pressure with, for example, the venturi mechanisms 114.
The vacuum source controller 136 may include computing hardware (e.g., processors, memory, storage devices, communication devices, other types of hardware devices including circuitry, etc.), and/or computing instructions (e.g., computer code) that when executed by the computing hardware cause the vacuum source controller 136 to provide its functionality. The vacuum source controller 136 may include a lookup table or other data structure usable to determine the operating points for the one or more control valves 128, 130 based on a desired vacuum flow level. Once operating points are determined, the vacuum source controller 136 may modify operation of one or more of the control valves 128, 130 based on the operating points. For example, vacuum source controller 136 may modify the quantities of power used to drive control valves 128, 130 to set the quantity of fluid flow through each of the ports 116, 118, and/or 120.
In some embodiments, to limit or prevent contamination of the ambient environment with any undesired material 16, the sound attenuation chamber 40 may be configured remove undesired material 16 from the vacuum-induced fluid flow 26 prior to exhaustion into the ambient environment. To do so, the sound attenuation chamber 40 may be pneumatically connected to the vacuum source 38. In some embodiments, the sound attenuation chamber 40 is pneumatically connected to the vacuum source 38 by a conduit (e.g., a hose). In some embodiments, for example, as shown in
In some embodiments, the vacuum source 38 and the sound attenuation chamber 40 may be configured such that the vacuum source 38 and the sound attenuation chamber 40 may be relatively easily separated from one another. This may facilitate maintenance and/or cleaning of the vacuum source 38 and/or the sound attenuation chamber 40. In some embodiments, this may facilitate conversion of the unified vacuum and attenuation module 100 for tailoring it to different uses. For example, this may facilitate attachment of different vacuum sources (e.g., having different features, sizes, and/or capacities) to the sound attenuation chamber 40, and/or attachment of different sound attenuation chambers (e.g., having different features, sizes, and/or capacities) to the vacuum source 38.
Applicant has recognized that some industrial environments, such as the example environments including a reaction vessel 14 shown in
The sound attenuation chamber 40, in some embodiments, may both filter materials received from fluid flows before exhausting the received fluid flows and attenuate sound from received fluid flows before exhausting the received fluid flows into the ambient environment. In some embodiments, the sound may be attenuated to an extent that personnel in the area need not wear hearing protection, although personnel may need to wear hearing protection for other reasons.
In some embodiments, to filter undesired material 16 entering the sound attenuation chamber 40, the sound attenuation chamber 40 may include one or more inlet ports 142, one or more discharge ports 144, and/or one or more exhaust ports 146. At least some of the ports may be positioned on the attenuation housing 138 to provide access to the interior volume 140 from outside the attenuation housing 138. For example, the respective ports may include holes, apertures and/or other structures through one or more walls of the attenuation housing 138 that enable access to interior volume 140.
The inlet ports 142 may be pneumatically connected to the vacuum source 38. When pneumatically connected to the vacuum source 38, the inlet ports 142 may receive vacuum-induced flow 26 from the vacuum source 38. The minor portion of the undesired material 16 may be entrained in vacuum-induced flow 26, thereby presenting a potential contamination hazard if exhausted into the ambient environment without further filtering and/or treatment.
The exhaust ports 146, in some embodiments, may be pneumatically connected to the ambient environment. The fluid flow path through the material extraction assembly 10 may end at the exhaust ports 146. Consequently, in some embodiments, vacuum-induced flow 26 drawn from the source of the fluid (e.g., the reaction vessel 14,
In some embodiments, to partially attenuate sound, the exhaust ports 146 may be of substantially larger size than the inlet ports 142. The size difference between these ports may reduce or eliminate backpressure on the vacuum-induced flow 26. The flow path may expand greatly in cross-sectional area as the vacuum-induced flow 26 transitions from the inlet ports 142 into the interior volume 140. As a result, any sound generated by the vacuum-induced flow 26 may generally occur at an interface between the inlet ports 142 and the interior volume 140. In some embodiments, accordingly, the sound attenuation chamber 40 may, in part, dissipate the sound generated by the vacuum-induced flow 26 by generating it within the sound attenuation chamber 400, for example, such that the sound will dissipate prior to exiting the sound attenuation chamber 40.
In some embodiments, to filter undesired material 16 prior to exhaustion to the ambient environment, the interior volume 140 may include a filter media region 148. The filter media region 148 may include a portion of the interior volume 140 in which filter media 150 may be positioned. The filter media region 148 may be positioned, for example, such that the vacuum-induced flow 26 must substantially flow through the filter media region 148 and filter media 150 prior to being exhausted through the exhaust ports 146 to the ambient environment. In some embodiments, the interior volume 140 may include a filter media support plate 152. The filter media support plate 152 may be configured to support the filter media 150 within the filter media region 148. In some embodiments, the filter media support plate 152 may generally divide the interior volume 140 into two or more sections and may include holes through which the vacuum-induced flow 26 may travel between the sections. One or both sides of the filter media support plate 152 may include one or more baffles 154 configured to attenuate sound. The one or more baffles 154 may attenuate sound generated by the vacuum-induced flow 26, for example, prior to exhaustion out of the sound attenuation chamber 40.
In some embodiments, to filter undesired material 16 prior to exhaustion to the ambient environment, the filter media 150 may be configured to filter at least a portion of the minor portion of the undesired material 16 from the vacuum-induced flow 26. The filter media 150 may include any type of filter media for removing material from fluid flows. The filter media 150 also may be sound absorptive and, in part, help to dissipate the sound generated by the vacuum-induced flow 26. The filter media 150 may, in some examples, exhibit a relatively limited filtration capacity. As filter media 150 filters the undesired material 16, its permeability to fluid flow may decrease.
To manage the filtration capacity of the filter media 150, in some embodiments, the sound attenuation chamber 40 may include one or more jet generators 156 positioned relative to the sound attenuation chamber 40 to generate jets of fluid flow directed toward the filter media 150 to at least partially maintain the filtration capacity of the filter media 150. For example, the jet generators 156 may be positioned to generate jets of fluid flow directed toward the filter media 150 to at least partially refresh or restore the filtration capacity of filter media 150. For example, the jet generators 156 may be positioned outside the attenuation housing 138 and oriented facing into the filter media region 148.
When the jet generators 156 generate the jets, the jets may transfer undesired material 16 filtered by the filter media 150 out of the filter media 150 and into the interior volume 140. This may, in some embodiments, at least partially restore the permeability and/or the filtration capacity of the filter media 150. For example, the jets may cause undesired material 16 trapped in the filter media 150 to drop out of the filter media region 148, for example, through holes in the filter media support plate 152 and into interior volume 140.
To drive the jet generators 156, in some embodiments, the sound attenuation chamber 40 may include a jet fluid supply 158. The jet fluid supply 158 may be configured to store compressed fluid. In some embodiments, the jet fluid supply 158 may include a storage tank in which the compressed fluid is stored. The compressed fluid may be a gas, such as, for example, compressed air. The jet fluid supply 158 may be pneumatically coupled to the jet generators 156. The jet generators 156 may include one or more ports and one or more electrically driven actuators configured to control the rate at which the compressed fluid from the jet fluid supply 158 exits the jet generators 156. Thus, the jet generators 156 may modulate one or more of a strength of the jets of fluid flow, timing of the jets of fluid flow, or one or more other characteristics associated with the jets of fluid flow.
To fill the jet fluid supply 158, in some embodiments, the sound attenuation chamber 40 may include a fluid supply port 160. The fluid supply port 160 may be pneumatically connected to the jet fluid supply 158 to refill the jet fluid supply 158 with compressed fluid, for example, when another source of compressed fluid (e.g., the fluid source 42) is pneumatically coupled to the fluid supply port 160.
In some embodiments, due to a limited size of the interior volume 140, only a finite quantity of undesired material 16 may be stored in the interior volume 140. Over time the interior volume 140 may become filled with undesired material 16 as undesired material 16 is removed from the source of the material (e.g., the reaction vessel 14). Once the interior volume 140 is filled, the sound attenuation chamber 40 may become inoperable, for example, undesired material 16 may block fluid flow through the interior volume 140.
To manage the fill level 79 of the interior volume 140, in some embodiments, the sound attenuation chamber 40 may include one or more discharge ports 144. The discharge ports 144 may facilitate removal of undesired material 16 from the interior volume 140. In some embodiments, undesired material 16 may be removed from the interior volume 140 through the discharge port(s) 144 while the vacuum-induced flow 26 flows through the interior volume 140.
To remove undesired material 16 from the interior volume 140, in some embodiments, the discharge port 144 may be pneumatically connected to a material collector 36 (e.g., a vacuum box 48). For example, the discharge port 144 may be pneumatically connected to a material collector 36 via a conduit 162 (e.g., such as a restrictive hose). When a high-pressure vacuum is applied to the material collector 36, undesired material 16 in the interior volume 140 may be drawn out of the interior volume 140, through the conduit 162, and into the material collector 36. Thus, both the major portion and the minor portion of the undesired material 16 extracted from the source of the material (e.g., the reaction vessel 14) may be transferred to a material collector 36. The discharge port 144 may be pneumatically connected to other components for undesired material discharge purposes without departing from embodiments disclosed herein.
To control when and/or the rate of removal of the undesired material 16 from the interior volume 140, in some embodiments, the sound attenuation chamber 40 may include a discharge port control valve 164. The discharge port control valve 164 may be positioned to control the rate of fluid flow through the discharge port 144. For example, the discharge port control valve 164 may include an electrically driven actuator usable to control the rate of fluid flow through discharge port 144. In some embodiments, the discharge port control valve 164 may control the rate of fluid flow through discharge port 144 to selectively remove undesired material 16 from the interior volume 140.
To determine when and/or at which rate to remove undesired material 16 from the interior volume 140, in some embodiments, the sound attenuation chamber 40 may include one or more sensors 166. The sensors 166 may be positioned to monitor the filtration capacity of the filter media 150, the fill level 79 of the interior volume 140, and/or the flow rate of undesired material 16 out of the discharge port 144. The sensors 166 may be configured to generate signals indicative of any physical property of the sound attenuation chamber 40 and use the signals to determine these quantities. For example, the sensors 166 may include photo-sensors that measure the filtration capacity of the filter media 150 based on a quantity of light transmitted by the filter media 150. In some embodiments, the sensors 166 may include a transducer configured to measure the mass of undesired material 16 to determine the fill level 79 of the interior volume 140. The sensors 166 may include other components for measuring the same or different types of physical properties without departing from embodiments disclosed herein.
In some embodiments, the chamber controller 168 may include computing hardware (e.g., processors, memory, storage devices, communication devices, other types of hardware devices including circuitry, etc.), and/or computing instructions (e.g., computer code) that when executed by the computing hardware cause chamber controller 168 to provide its functionality. The chamber controller 168 may include a lookup table or other data structure usable to make an operating points determination 170 for the discharge port control valve 164 and/or the jet generators 156 based at least in part on the fill level 79 and filtration capacity of the filter media 150. Once the operating points are determined, the chamber controller 168 may be configured to modify operation of the discharge port control valve 164 and/or the jet generators 156 based at least in part on the operating points. For example, the chamber controller 168 may be configured to modify the quantities of power used to drive the discharge port control valve 164 and/or the jet generators 156 to set the quantity of fluid flows through each of the discharge port control valves 164 and/or the jet generators 156. As a result, in some embodiments, the sound attenuation chamber 40 may be more likely to be able to substantially continuously operate.
In some embodiments, to enable a person to control operation of the sound attenuation chamber 40, the sound attenuation chamber 40 may include a user input device 172. The user input device 172 may be in communication with to the chamber controller 168. The user input may be communicated to the chamber controller 168 via the user input device 172. The user input device 172 may include, for example, one or more buttons, touch sensitive displays, levers, knobs, and/or other devices (e.g., control panels, tablet computers, and/or smart phones) that are operable by a person to provide the chamber controller 168 with information for operating or controlling the sound attenuation chamber 40.
The chamber controller 168 may be configured to receive information from a person via the user input device 172 regarding how frequently to refresh the filtration capacity of the filter media 150 and/or information regarding how frequently to discharge undesired material 16 from the interior volume 140. The chamber controller 168 may use such information when determining the operating points for the discharge port control valve 164 and/or the jet generators 156. For example, a person may provide operational preferences or other information using the user input device 172 to configure operation of the sound attenuation chamber 40.
In some embodiments, the chamber controller 168 may be powered using electricity. The sound attenuation chamber 40 may include one or more solar panels 174 that provide electrical power to the chamber controller 168. The chamber controller 168 may include one or more batteries in which power from the one or more solar panels 174 may be stored prior to use by the chamber controller 168 (and/or other controllers of the material extraction assembly 10).
Applicant has recognized that some environments, such as industrial environments similar to the environment illustrated in
In some embodiments, various components may utilize fluid flows to provide their functionalities. To operate these components, the material extraction assembly 10 or material conveyance assembly 11 may include the fluid source 42, which may be a mobile fluid supply. The fluid source 42 may be configured to supply pressurized or compressed fluid to the vacuum source 38 and/or the sound attenuation chamber 40. The fluid supplied may be may be pneumatically connected to the vacuum source 38 (e.g., to generate vacuums) and/or the sound attenuation chamber 40, for example, to refresh the filtration capacity of the filter media 150.
To supply pressurized or compressed fluid, the fluid source 42 may compress fluid and store the compressed or pressurized fluid for future use. In some embodiments, the fluid source 42 may include an air compressor, and the air compressor may be configured to compress air from the ambient environment to generate the compressed or pressurized fluid. The fluid source 42 may compress other fluids without departing from embodiments disclosed herein.
To limit or prevent combustion risk, in some embodiments, the fluid source 42 may compress fluid using electricity. The fluid source 42 may obtain the electricity from any electricity source. In some embodiments, the fluid source 42 may include one or more batteries for providing the electricity to the fluid source 42. In some embodiments, the fluid source 42 may include a power cable and/or other componentry for obtaining electricity from another source (e.g., from a utility company or other large scale supplier, a solar setup, and/or or other non-combustion-based electricity producers, etc.).

Applicant has recognized that environments, such the example environment shown in
For example, as shown in
By pneumatically connecting both material collectors 36, for example, to the source of the material (e.g., the reaction vessel 14) in parallel, undesired material 16 from the source of the material may be transferred to both material collectors 36 concurrently or substantially simultaneously. As a result, the material extraction assembly 10 may be capable of removing twice as much undesired material 16 before the material collectors 36 are filled. The material removal capacity of a material extraction assembly 10 in accordance with some embodiments may be scaled up (or down) as desired in this example manner to meet environment-based requirements. In such embodiments, any of the components may include any number of ports to facilitate the formation of multiple fluid flow paths. For example, as seen in
Each material collector 36 may be pneumatically connected to two vacuum sources 38 through hoses 182. By pneumatically connecting two vacuum sources 38 to a single material collector 36, the strength of the high-pressure vacuum in the material collector 36 may be increased. Consequently, a higher degree of suction may be applied to undesired material 16 in reaction vessel 14, thereby increasing the transfer rate of undesired material 16 from reaction vessel 14 and allowing more difficult material to be transferred out of reaction vessel 14. The suction strength of the material extraction assembly 10 in accordance with embodiments may be scaled up (or down) as desired in this example manner to meet environment requirements.
In some embodiments, each of the vacuum sources 38 pneumatically connected to a material collector 36 may be driven with fluid flow from a corresponding fluid source 42 (e.g., a mobile fluid supply). For example, the fluid sources 42 (e.g., gas supplies) may be pneumatically connected to corresponding vacuum sources 38 through conduits 184.
In some embodiments, each of the vacuum sources 38 pneumatically connected to a material collector 36 and/or suction manifold 44 may also exhaust through a corresponding sound attenuation chamber 40. For example, the vacuum sources 38 that exhaust through a corresponding sound attenuation chamber 40 may be positioned on a trailer together to form a mobile unit. In this manner, the material extraction assembly 10 or material conveyance assembly 11 may be quickly and efficiently deployed and scaled up (or down) as desirable to meet environment requirements.
To facilitate efficient reconfiguration of the material extraction assembly 10 or material conveyance assembly 11, any of the pneumatic connections may be implemented using quick connect-disconnect connections and/or pneumatic isolators. The quick connect-disconnect connections may allow for any of the pneumatic connections to be quickly made and removed. The pneumatic isolators may automatically seal the material removal system when a pneumatic connection is disconnected. For example, pneumatic isolators may be positioned between the divider 176 and the material collectors 36. When one of conduits 180 is disconnected from the divider 176, the pneumatic isolator may automatically seal the opening in the divider 176, to which the disconnected conduit was connected. In this manner, the disconnection of a conduit may not impact the other fluid flow paths. For example, the fluid flow path between the divider 176 and the remaining connected material collector 36 (e.g., with the other conduit) may not be impacted. Quick connect-disconnect connections and/or pneumatic isolators may be used to facilitate the pneumatic reconfiguration of any of the fluidic topologies illustrated throughout this application.

The one or more chutes 190 may extend from the receiver 186 at least partially inside the reaction vessel 14. Desired material 192 in the receiver 186 may be, for example, pumped, gravity fed, or otherwise directed through the one or more chutes 190 into the reaction vessel 14. The desired material 192 may be deployed in one or more locations within the reaction vessel 14. The chute 190 may include various sections which may be removed, blocked, or otherwise separated from the flow of desired material 192 as different zones are filled. By doing so, the length of the conduit 190 may be adjusted to match each of the zones (or the heights of structures in the respective zones).
The desired material may take different forms. For example, in some embodiments, the desired material 192 may include new or recycled pall rings or other devices to facilitate a reaction in the reaction vessel 14. In some embodiments, the desired material 192 may be a catalyst material that was previously removed from the reaction vessel 14. The desired material 192 may be replacement catalyst or any other types of material without departing from embodiments disclosed herein. In some embodiments, the desired material 192 may be a different type of material that was not previously in the reaction vessel 14.
Some embodiments of the material extraction assembly 10 or material conveyance assembly 11 may include a number of components configured to cooperatively operate to provide its functionality. To orchestrate the operation of these components, in some embodiments, the operation of the material extraction assembly 10 or material conveyance assembly 11 may be coordinated in an at least partially automated manner. For example, as explained herein, any of the components of the material extraction assembly 10 or material conveyance assembly 11 may include a supervisory controller 81, which may coordinate operation of one or more of the components.

The example method 1800, at 1804, may include supplying the pressurized fluid to a vacuum source configured to generate a vacuum flow using the pressurized fluid, for example, as described herein. In some embodiments, one or more conduits may be provided between one or more fluid sources and the vacuum generator to supply pressurized fluid from the one or more fluid sources to the vacuum source, for example, as described herein.
At 1806, the example method 1800, may include generating a vacuum flow via the vacuum source, for example, as described herein. For example, the vacuum source may include a plurality of vacuum generators configured to use the pressurized fluid to generate the vacuum flow. In some embodiments, the vacuum source may include two or more, three or more, or four of more vacuum generators. In some embodiments, one or more of the vacuum generators may include a venturi mechanism configured to use the pressurized fluid flow the generate the vacuum flow.
The example method 1800, at 1808, may include determining whether a vacuum pressure of the vacuum flow is sufficient to extract the material from the source of the material, for example, as described herein. For example, pressure sensors and/or flow rate sensors may be provided upstream and/or downstream of the vacuum source, and a controller may receive sensor signals from the sensors and determine whether the vacuum pressure is sufficient. In some embodiments, the controller may be configured to compare the pressure and/or flow rate determined based at least in part of the sensor signals and compare the pressure and/or flow rate to pressure and/or flow rate information stored in memory (e.g., via a look-up table) for different types of materials that may be extracted. In some embodiments, an operator of the system may input, for example, via a user input device, the type of material being extracted, and the controller may be configured to determine the pressure and/or flow rate appropriate for extracting the type of material input by the operator. In some embodiments, the controller may be configured to automatically determine the type of material being extracted, for example, via infra-red sensors, image sensors, optical sensors, and/or laser sensors, such as LIDAR, and analytical models, such as, for example, machine-learning-trained analytical models. Other ways of determining sufficient vacuum pressure are contemplated.
If, at 1808, is determined that the vacuum pressure is not sufficient to extract the material, at 1810, the example method 1800 may include increasing one or more of a flow rate of the pressurized fluid supplied to the vacuum source or increasing the pressure of the pressurized fluid supplied to the vacuum source.
Thereafter, the example method 1800 may include returning to 1808 to determine whether the vacuum pressure of the vacuum flow is sufficient to extract the material from the source of the material.
If, at 1808, it is determined that the vacuum pressure of the vacuum flow is sufficient to extract the material from the source of the material, at 1812, the example method 1800 may include determining whether the vacuum pressure is too high to efficiently extract the material from the source of material. This may be performed in a manner at least similar to the example manner described with respect to 1808.
If, at 1812, it is determined that the vacuum pressure is too high, at 1814, the example method 1800 may include reducing one or more of a flow rate of the pressurized fluid supplied to the vacuum source or reducing the pressure of the pressurized fluid supplied to the vacuum source.
Thereafter, the example method 1800 may include returning to 1808 to determine whether the vacuum pressure of the vacuum flow is sufficient to extract the material from the source of the material.
If, at 1812, it is determined that the vacuum pressure is not too high, at 1816, the example method 1800 may include drawing material from the material source into a material collector via the vacuum flow to collect extracted material from the material source, for example, as described herein. One or more manifolds and/or one or more conduits may be provided between the source of the material and the material collector to convey the extracted material to the material collector, for example, as described herein.

The example method 1800, at 1820, may include determining whether the material collector has reached a first threshold amount of extracted material, for example, as described herein. In some embodiments, one or more sensors may be provided to generate signals indicative of the amount of extracted material in the material collector, for example, as described herein. In some examples, a controller may be provided and configured to receive the sensor signals, and based at least in part on the sensor signals, determine whether the first threshold has been met.
If, at 1820, it is determined that the material collector has reached the first threshold amount, at 1822, the example method 1800, may include operating a drive unit connected to a device in the material collector configured to distribute the extracted material collected in the material collector throughout the material collector, for example, as described herein. For example, the drive unit may be connected to an auger configured to rotate via the drive unit and redistribute at least some of the extracted material within the material collector, for example, as described herein.
At 1824, the example method 1800 may include determining whether the material collector has reached a second threshold amount of extracted material approaching maximum capacity of the material collector, for example, as described herein. In some embodiments, as noted above at 1820, one or more sensors may be provided to generate signals indicative of the amount of extracted material in the material collector. In some examples, a controller may be provided and configured to receive the sensor signals, and based at least in part on the sensor signals, determine whether the second threshold has been met.
If, at 1824, it is determined that the material collector has reached the second threshold amount of extracted material, at 1826, the example method 1800 may include causing the vacuum flow through the material collector to stop. This may include, for example, closing a valve in the conduit between the source of the material and the material collector to prevent the extracted material from continuing to flow into the material collector. In some embodiments, this may include ceasing the method 1800 until, for example, the material collector may be emptied or the conduit may be connected to a different material collector. In some embodiments, the conduit connecting the material collector to the source of the material may be disconnected from the source of the material and another material collector may be connected to the conduit. Thereafter, the method 1800 may be restarted. The full material collector may be taken to a location for disposal of the extracted material, recycling of the extracted material, or remediation of the extracted material.
If, at 1824, it is determined that the material collector has not reached the second threshold amount of extracted material approaching maximum capacity of the material collector, at 1828, the example method 1800 may include conveying a minor portion of the extracted material to a sound attenuation chamber via the vacuum flow, for example, as described herein. For example, a conduit may be provided between the material collector and the sound attenuation chamber providing a flow path for the vacuum flow to convey the minor portion of the material (e.g., material not trapped in the material collector) to the sound attenuation chamber. In some embodiments, the sound attenuation chamber of the vacuum source may be connected to one another (e.g., directly connected to one another), for example, to form a unitary vacuum and attenuation module, for example, as described herein.
At 1830, the example method 1800 may include attenuating, via the sound attenuation chamber, sound generated by the vacuum flow and/or generation of the vacuum flow, for example, as described herein.
The example method 1800, at 1832, may include passing the vacuum flow including the minor portion of the extracted material through filter media associated with the sound attenuation chamber (e.g., at least partially enclosed within the sound attenuation chamber) to capture at least a portion of the minor portion of extracted material in the filter media, for example, as described herein.
At 1834 (see
If, at 1834, it is determined that the flow of the vacuum flow through the filter media may be at least partially impeded by build-up of the extracted material in the filter media, at 1836, the example method 1800 may include generating jets of fluid flow directed toward the filter media to dislodge at least a portion of the extracted material from the filter media, for example, as described herein. In some embodiments, the example method 1800 may include periodically generating the jets of fluid flow directed toward the filter media instead of, or in addition to, determining whether flow of the vacuum flow through the filter media may be at least partially impeded by build-up of the extracted material in the filter media. For example, the jets of fluid flow directed toward the filter media may be initiated based on parameters, such as, for example, the amount of time the material extraction assembly has been operating, the pressure level and/or flow rate of the vacuum flow, and/or the type of material being extracted from the material source. One of more of these parameters may be determined based at least in part on, for example, sensor signals, a controller, and/or operator input.
At 1838, the example method 1800 may include collecting the dislodged extracted material in an attenuation housing of the sound attenuation chamber, for example, as described herein. For example, the jets of fluid, when generated may cause at least a portion of the extracted material trapped in the filter media to fall from the filter media into the attenuation housing for collection.
The example method 1800, at 1840, may include determining whether the attenuation housing has reached a first threshold amount of extracted material, for example, as described herein. This may be performed in a manner at least similar to the example manner described with respect to 1820 above.
