Description
TECHNICAL FIELD

The embodiments presented relate to an expeditionary solid waste disposal system configured to improve logistics and enable it to be readily deployed in a military or civilian environment.


BACKGROUND

Many workforce camps, humanitarian and refugees' camps and military bases have difficulty safely and efficiently disposing of solid waste. The logistical challenges presented by the austere locations and often severe climatic conditions have made traditionally configured incinerators impractical. Without the option for better methods many have been forced to utilize crude and polluting disposal methods such as burn pits and small, ineffective incinerators that were not purpose-built.


In particular, rural and limited-access regions, have less infrastructure and cannot properly dispose of waste. Land disposal of waste is not appropriate in many areas due to topographic, hydrogeological, and/or climatic conditions. If waste is not properly disposed of, serious health conditions and environmental impacts may arise. Incinerators offer a possible solution. However, many current systems are difficult to transport and require too many resources which are not available in remote locations.

DETAILED DESCRIPTION

The specific details of the single embodiment or variety of embodiments described herein are to the described system and methods of use. Any specific details of the embodiments are used for demonstration purposes only and not unnecessary limitations or inferences are to be understood therefrom.


Before describing in detail exemplary embodiments, it is noted that the embodiments reside primarily in combinations of components related to the system and method. Accordingly, the system components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.


As used herein, relational terms, such as “first” and “second” and the like, may be used solely to distinguish one entity or element from another entity or element without necessarily requiring or implying any physical or logical relationship or order between such entities or elements.


Specifically, the apparatus enables gasification and oxidation using a plurality of proprietary combustion chambers connected via an air duct and controlled using burners, variable speed blower, air dampers and microprocessor-controlled automation which enables two-stage gasification and oxidation.


The embodiments provide a highly portable and readily assemblable containerized waste conversion apparatus which enables recovered heat from gaseous effluent to be converted to a plurality of energy sources using releasably attached energy generation systems. The apparatus includes at least a primary and secondary combustion chamber, breech/control chamber, and heat recovery module chamber which are releasably secured to one another using a locking mechanism and collectively affixed to an integrated skid type base. The apparatus is designed to enable a single person with a forklift operator to releasably attach each iso-container using the container connecting devices, and releasably attach each interconnecting air duct, and blower and burner using an integrated slide rail system, quick connection cables and hoses without the need for a crane.


The apparatus is controlled by a microcontroller having integrated storage and remotely connected to the main control panel housed within the control chamber. During operations, an operator may batch load up to 1000 pounds of waste per day within the first combustion chamber which provides for over a 96 percent reduction of the load waste mass. Upon completion of the time gasification/oxidation (i.e., burn cycle), the apparatus initiates a cool-down mode, once completed an operator is allowed to open the door to remove the ash collected. The door, in some embodiments includes a temperature-controlled door lock that prevents a person from being able to open the door until the internal temperature is below 90 degrees Celcius. The waste can include mixed, unsorted, non-hazardous solid waste on a consecutive daily basis including time for cooling between batches and routine maintenance such as ash removal activities.


In contrast to the present embodiments, traditional mobile waste processing systems are typically housed within a single 20-foot iso container and often require manual sorting of the solid waste before it is placed within a shredder for further mass reduction and homogeneity. The traditional system, which is constructed then housed within a commercial shipping container, is not able to utilize to entire shiping envelope as space for waste processing capacity or the oxidation of the gases. Therefore, inherent to the traditional design is a loss of up a minimum of 10% and up to 40% of the available shipping volume due to the redundancy of the outer shipping container. The apparatus has a unique construction whereby the wall of the primary and secondary combustion chambers are also the outer wall of the container and it is outfitted with all of the required shipping container features but without the addition of an outer shipping container, maximizing the internal volumes for the device allowing it process more waste and oxidize more gaseous by-products than is possible within the traditional configuration.


Referring now to the drawings wherein like referenced numerals designate identical or corresponding parts throughout the views. There is shown in FIG. 1 a mobile and readily assemblable containerized multi-stage waste-to-energy recovery apparatus 10. The apparatus 10 includes a plurality of combustion chambers 12 a microcontroller 16 remotely connected to main control panel 18. The portable apparatus 10 is dimensioned to be transported using a variety of transport platforms including at least a semi-trailer, ship, helicopter, or within the cargo bay of transport aircraft and readily assembled by a single person and a forklift operator on-site using the container locking mechanism 60 and tool 61.


The plurality of chambers 12 further includes at least a first combustion chamber 20, a second combustion chamber 40, a control chamber 30. Each of the plurality of equilateral dimensioned chambers 12 is approximately 8.0 feet wide, 6′ feet and 5½ inches long, and 8.0 high with a steel exterior for strength coupled with lightweight insulating materials which reduce the weight of each compartment to 7,500-10,000 lbs.


The first combustion chamber 20 includes a ceramic fiber refractory lining 23 (further illustrated in FIG. 5) which is resistant to thermal shock due to the regular cycling from high temperatures during the burn cycle to low temperatures during the cooldown cycle that takes place in the first combustion chamber 20 during the close-coupled gasification. The dual chamber design of the first 20 and second combustion chamber 40 optimizes quality of the gaseous effluent by reducing the likelihood of release contaminants. The first 20 and second combustion chambers 40 are fluidly connected by an air duct 32 housed within the control chamber 30. The air duct, according to some embodiments, further connects an integrated variable speed, and in some embodiments, flow regulated, secondary blower 42 which creates a turbulent mixture of the contained air and gas molecules as they enter the secondary chamber where they are exposed to a minimum of 850 Degrees Celsius for a minimum of 2 seconds or 1000 Degrees Celsius for a minimum of 1 second allowing for complete oxidation of contained effluents. Before use, waste is batch loaded into the first combustion chamber 20 through the main door 21 where it is placed on a metal grate 28 above the ceramic firebrick floor surface 27 having at least one removable grate. Once the first combustion chamber 20 is fully loaded with waste, the main door 21 is closed and the plurality of safety features 22 are engaged to protect an operator by immediately terminating the gasification/oxidation.


A fuel tank which supplies the primary burner 24 and secondary burner 41 collapsible fuel tank that stores within the first combustion chamber 20.


Shown in FIG. 2 is a cross-sectional view of the first combustion chamber 20 with the main door 21 open. The apparatus 10 is designed to enable a single operator to batch load up to one thousand pounds of waste through the main door 21. Once the waste is placed onto the metal grate 28 above the ceramic firebrick floor surface 27, the main door 21 is closed and the plurality of safety devices 22 are initiated. Shown in FIG. 7 the burn cycle may be started either automatically using a programmed cycle or manually operated at the main control panel 18. When the gasification/oxidation process has begun, the microcontroller 16 provides a plurality of output commands to both the primary blower 25 and secondary blowers 42 which are electrically connected to a countdown timer 19 and programmed to run for a pre-determined period to ensure any residue from gaseous effluent has been exhausted within the first 20 and second combustion chambers 40 prior to lighting the secondary burner 41. Upon expiration of this pre-programmed “exhaust period,” the secondary burner 41 is lit until the pre-programmed set point temperature of 850-1000 degrees Celsius is reached. The primary burner 24 is further controlled by the microcontroller 16 and configured to light once the pre-programmed set point temperature of 650-800-degree Celsius is reached within the primary (first) chamber 20.


During the gasification process, the loaded solid waste is first dried to remove any moisture within the waste and then begin to decompose any contained organic molecules to form a gas vapor composed of water, carbon monoxide, carbon dioxide, hydrogen, methane, and ethane, etc. Once the gasification process is complete, any remaining solid waste is removed along with the ash collected along the ceramic firebrick floor surface 27 and under the removable metal grate 28.


Shown in FIG. 6, the primary burner 24 and primary blower 25 are electrically connected to at least one mounted sensor 26 which regulates the pre-programmed temperature of the first primary (first) chamber 20 by sending an output signal to the microcontroller.


Shown in FIG. 6, the at least one mounted sensor 43, for example thermocouple of the secondary combustion chamber 40 is further configured to regulate the pre-programmed set point temperature within the second combustion chamber 40 using a secondary blower 42 controlled by variable frequency drive, secondary burner 41 which modulates between 25%-100% (Low fire to high fire). An automatic air damper is activated by modular motor to help to control fresh air input.


Shown in FIG. 3 When operating the apparatus 10 in a heat recovery mode, the gaseous effluent may be selectively directed using a draft induction blower 71 to heat exchanger 72 then discharges from a heat recovery exhaust stack 74. The heat exchanger 72 further includes a plurality of water coils 73 which are heated through convection and radiation, and the liquid contents circulated throughout the closed loop system using the water circulation pump 75. When configured in the heat recovery mode, the gaseous effluent is redirected from the heat recovery exhaust stack 74 to the main exhaust stack 50 once the at least 500-gallon capacity of the at least one water tank 76 is reached.


In some embodiments, the main exhaust stack 50 emits no visible emissions during operation and is shown to have low in-stack emissions. When the waste mixture is thermally destroyed, the remaining ash has no toxicity characteristics as defined by the US Environmental Protection Agency (EPA) regulations when subjected to the toxicity characteristic leachate procedure (TCLP).


Once the close-coupled gasification within the first 20 and second combustion chambers 40 are complete, the microcontroller 16 initiates a pre-programmed cool down cycle using the primary blower 25 and secondary blower 42 to exhaust any residue gas. Similar to the burn cycle which is operated with a countdown timer, the cool-down mode may be pre-programmed for a pre-selected period of time-based on factors such as operational tempo, climate, and operating conditions. For example, if the apparatus 10 is transported to a cold environment with minimal waste, both the burn cycle and cool down period may be shortened to preserve fuel consumption. Conversely, if transported to a tropical environment, the cooldown period may be extended to account for the warmer temperatures. Suitable fuels include diesel, or JP-8 fuel stored within the self-contained fuel system. The fuel bladder can be folded into the interior of the apparatus 10 during transportation.


Now shown in FIG. 3 is a schematic view of the apparatus 10 which is configured to provide a storable heated liquid when used in the heat recovery mode. During use in the heat recovery mode, the gaseous effluent is directed from the heat recovery module 70 to the heat exchanger 72 where the heat molecules communicate through convection and radiation with the plurality of water coils 73 to warm the contained liquid. Though it is contemplated the heat exchanger 72 is comprised of a plurality of water coils 73 which are heated using convection and radiation, the heat exchanger 72 may be further equipped with shell and tube exchangers, plates, with or without fins.


Further illustrated in FIG. 3 is a variable speed draft induction blower 71 within the heat recovery module 70 which creates fluid suction from the second combustion chamber 40 to the heat exchanger 72 and heat recovery exhaust stack 74. During the convection cycle, the gaseous effluent heats the contained liquid within the plurality of water coils 73 which is later transformed back to cool liquid at the cooling interface. The liquid is stored with the at least one water storage tank 76 then circulated by the circulation pump 75.


Now shown in FIG. 4 is a schematic view of the apparatus 10 which enables a variety of water-to-energy mechanisms to be operated including a heat exchanger 72, and at least an organic Rankine cycle unit 81 or a absorption chiller 82, or a thermoelectric generator 83 to be used in conjunction with another heat exchanger 80. The heat exchanger 72 may be, but not limit to be shell and tube exchangers with or without fins, or heat pipe heat exchanger. The heat exchanger 80 may be, but not limit to be shell and tube exchangers with or without fins, plate and frame heat exchanger. The heat transfer medium runs between two heat exchanger 72 and 80 may be thermal oil, organic matter, water, or air.


Now shown in FIG. 5 is a detailed view of the first primary (first) chamber 20 including the ceramic firebrick floor 27 and refractory lining 23. The first primary (first) chamber 20 weighs approximately 10,000 pounds and allows for convenient positioning using a forklift. The first primary (first) chamber 20 and is releasably coupled to the 7,500-pound control chamber 30 using a plurality of positionable locking components 60 which are attached about the steel corner blocks. During disassembly of the apparatus 10, the operator must first disconnect the primary blower 25 and secondary burner 41, and air duct 32 by the integrated sliding rail mechanism 33. Each of the interchangeable components of the apparatus 10 is designed for rapid “break down” without the need for heavy equipment.



FIG. 6 illustrates a block diagram of an exemplary configuration of the microcontroller 16 and the control architecture. Microcontroller 16 is in operable communication with a memory 17, and main control 18. The heat recovery module 70 includes pump 75, the heat exchanger 72, Organic Rankine Cycle (ORC) unit or absorption chiller 82, or thermoelectric generator 83 which are each in operable communication with the microprocessor 16. Draft induction blower 71 forces Flue gas to heat exchanger 72 and exit to stack 74.
