The present invention relates to a system for controlling a pressure of a fluidic product, and more specifically relates to a pressure regulation system for reaction treatment of the fluidic product having particles at elevated temperature and pressure.
Using a decomposing reactor, the fluidic product, such as an aqueous solution having particles, is decomposed into a treated product through one or more chemical reactions. In certain cases, the particles of the aqueous solution include biological materials, such as fiber (e.g., cotton) particles, or in some cases, include organic materials, such as plastic particles.
During operation, the aqueous solution is stirred and heated in the decomposing reactor at high temperature and pressure for inducing the chemical reactions for the biological materials and/or the organic materials in the aqueous solution. The decomposing reactor produces the treated product through the chemical reactions of the biological materials and/or the organic materials in the aqueous solution.
At the end of the reaction treatment of the aqueous solution, the treated product can be discharged into the atmosphere for further processing. However, due to the high pressure accumulated in the decomposing reactor, the treated product is controllably discharged using a backpressure regulator. The backpressure regulator is typically installed at a distal end of a piping system connected to the decomposing reactor. For controlling a discharge flow of the treated product, the backpressure regulator creates an obstruction to the discharge flow to maintain the backpressure of the treated product when the treated product discharged from the piping system.
As such, although existing backpressure regulators provide certain flow control for the treated product, one disadvantage of the existing backpressure regulators is that the discharge flow of the treated product is frequently interrupted because the backpressure of the treated product is only intermittently or periodically controlled.
In one example, a pressure relief valve can be used to control one or more inadvertent pressure occurrences only, not for steady state flow control. When the backpressure exceeds a predetermined value, the pressure relief valve opens to relieve an excess pressure. Thus, the discharge flow of the treated product is noncontinuous and recurrently disrupted.
In another example, a pressure regulator having a set-point pressure spring and a diaphragm can be used to control the backpressure of the treated product. However, one disadvantage of such pressure regulators is a clogging problem when the treated product includes particles, such as the fiber particles or the plastic particles. Existing configurations of such pressure regulators are prone to clogging during operation due to the particles. Correcting the clogging frequently can be time consuming and also can cause increased operational expenses.
Thus, there is a need to develop an enhanced pressure regulation system for the fluidic product having particles that overcomes one or more above-described disadvantages of the existing backpressure regulators.
In one embodiment of the present disclosure, a method of maintaining a backpressure of a fluidic product is provided. The method includes pressurizing a first reservoir to a first predetermined pressure level using compressed air, delivering the fluidic product to the pressurized first reservoir until a current level of the fluidic product in the first reservoir reaches a first predetermined level, pressurizing a second reservoir to a second predetermined pressure level using the compressed air, delivering the fluidic product to the pressurized second reservoir until a current level of the fluidic product in the second reservoir reaches a second predetermined level, and controlling the backpressure of the fluidic product using the first reservoir and the second reservoir such that a discharge flow of the fluidic product is continuous.
In one example, the method further includes continuously delivering the fluidic product to the second reservoir when an intake of the fluidic product into the first reservoir is discontinued. In one variation, the method further includes transitioning the first reservoir into an unpressurized state after discontinuing the intake of the fluidic product into the first reservoir. In another variation, the method further includes equalizing the first reservoir with atmospheric pressure to achieve the unpressurized state in the first reservoir. In yet another variation, the method further includes discharging the fluidic product from the first reservoir after transitioning the first reservoir into the unpressurized state. In still another variation, the method further includes discontinuing the discharging of the fluidic product from the first reservoir when the first reservoir is empty. In yet still another variation, the method further includes transitioning the first reservoir into a pressurized state after discontinuing the discharging of the fluidic product from the first reservoir.
In another example, the method further includes continuously delivering the fluidic product to the first reservoir when an intake of the fluidic product into the second reservoir is discontinued. In one variation, the method further includes transitioning the second reservoir into an unpressurized state after discontinuing the intake of the fluidic product into the second reservoir. In another variation, the method further includes equalizing the second reservoir with atmospheric pressure to achieve the unpressurized state in the second reservoir. In yet another variation, the method further includes discharging the fluidic product from the second reservoir after transitioning the second reservoir into the unpressurized state. In still another variation, the method further includes discontinuing the discharging of the fluidic product from the second reservoir when the second reservoir is empty. In yet still another variation, the method further includes transitioning the second reservoir into a pressurized state after discontinuing the discharging of the fluidic product from the second reservoir.
In another embodiment of the present disclosure, a system of maintaining a backpressure of a fluidic product is provided. The system includes an air supply assembly configured to pressurize a first reservoir to a first predetermined pressure level using compressed air, and pressurize a second reservoir to a second predetermined pressure level using the compressed air. Included in the system is a pump configured to deliver the fluidic product to the pressurized first reservoir until a current level of the fluidic product in the first reservoir reaches a first predetermined level, and to deliver the fluidic product to the pressurized second reservoir until a current level of the fluidic product in the second reservoir reaches a second predetermined level. Also included in the system is a controller is configured to control the backpressure of the fluidic product using the first reservoir and the second reservoir such that a discharge flow of the fluidic product is continuous.
In one example, the system further includes a backpressure regulator assembly being controllable by the controller. The backpressure regulator has an inlet, a first outlet, and a second outlet. The inlet is configured to receive the fluidic product and fluidically connected to both the first reservoir and the second reservoir. In one variation, the first outlet is fluidically connected to the first reservoir and the second outlet is fluidically connected to the second reservoir. In another variation, a first end of the first reservoir is fluidically connected to the inlet of the backpressure regulator assembly and an opposite second end of the first reservoir is fluidically connected to the air supply assembly, and a first end of the second reservoir is fluidically connected to the inlet of the backpressure regulator assembly and an opposite second end of the second reservoir is fluidically connected to the air supply assembly. In yet another variation, a first slurry supply valve is connected at one end to the inlet of the backpressure regulator assembly and at the other end to the first end of the first reservoir, and a second slurry supply valve is connected at one end to the inlet of the backpressure regulator assembly and at the other end to the first end of the second reservoir. In still another variation, a first slurry discharge valve is connected to the first end of the first reservoir, and a second slurry discharge valve is connected to the first end of the second reservoir. In yet still another variation, the controller is configured to automatically control opening and closing operations of at least one of: the air supply assembly, the first slurry supply valve, the second slurry supply valve, the first slurry discharge valve, and the second slurry discharge valve.

In one embodiment, the decomposing system 100 includes a raw material supply zone 104, a heating treatment zone 106, and a treated object retrieving zone 108. The decomposing system 100 performs a decomposing treatment for converting an aqueous solution 110 having a plurality of particles 112 into a treated product 114 to be stored in the treated object retrieving zone 108 for subsequent retrieval.
In embodiments, the regulation and control operations of the pressure regulation system 10 using the controller 14 refer to one or more backpressure maintenance operations conducted for keeping a primary pressure of the treated product 114 at a desired level. As an example only, an initial pressure of the treated product 114 before the operation of the pressure regulation system 10 can be approximately one megapascal (1 MPa) but a final pressure of the treated product 114 after the operation of the pressure regulation system 10 can be approximately zero (0) MPa.
In one embodiment, the controller 14 commands or instructs relevant valves to appropriately actuate corresponding valves, e.g., upwardly or downwardly, such that the primary pressure of the treated product 114 can be maintained during operation. In embodiments, the valves can include one or more valves shown in
Exemplary particles 112 include a biological material and/or an organic material. In one example, the biological material can include an agricultural waste, such as cotton, straw, corn, peanut byproducts and the like, and the organic material can include resin, plastic, polymer, polyester, and the like. Other suitable materials, such as inorganic substances, can also be included as the particles 112 to suit the application.
Other exemplary particles 112 can include different fiber materials. In one example, the fiber materials include plastic-based fibers, cellulose-based fibers, and/or protein-based fibers. For example, the plastic-based fibers include polyester, nylon, acrylic, and elastane fibers, the cellulose-base fibers include cotton, viscose, lyocell, and bast fibers (e.g., linen, hemp, or jute materials), and the protein-based fibers include wool and silk fibers.
The respective zones 104, 106, 108 can be arranged in the order shown in
In
A typical example of the tank 118 has a tank capacity of 1000 liters (L), a discharge pressure of 0.1 megapascal (MPa), and a flow rate of 10-40 liter per minute (L/min). However, the tank capacity, the discharge pressure, and the flow rate can vary to suit different applications. A pump 122, for example, can be connected to the feed path 120 for generating a high pressure that increases the discharge pressure of the aqueous solution 110 and for forcibly securing the flow rate of the aqueous solution 110 in the feed path 120.
As shown in
Further, the induction heating assembly 102 includes one or more heating induction coils 126 configured to surround at least a portion of the metal pipes 124, and a high-frequency power supply unit 128 configured to inductively drive the heating induction coils 126. In one embodiment, the heating induction coils 126 includes a first heating induction coil 134 surrounding a first portion of the metal pipe 124 and a second heating induction coil 136 surrounding a second portion of the metal pipe 124.
In order to use a hollow portion of the metal pipe 124 as a flow path for the aqueous solution 110, the metal pipe 124 has one end communicating with and connected to a discharge end of the feed path 120 of the raw material supply zone 104, and is made of stainless steel to be inductively heated by the heating induction coils 126.
A typical inner diameter of each metal pipe 124 is approximately 50 millimeters (mm) or 2 inches and a typical length of each metal pipe 124 is approximately 10 meters. In embodiments, the inner diameter of each metal pipe 124 can range between 2 and 4 inches, and the length of each metal type 124 can range between 10 and 80 meters depending on the type of substance of the particles 112 in the aqueous solution 110. For example, for cotton particles, the length can be about 10 meters, but for plastic particles, the length can be about 50 meters. However, the inner diameter and the length can vary to suit different applications.
In one embodiment, the metal pipe 124 may be disposed with an upward inclination to facilitate a feed of the aqueous solution 110 to be treated. However, in another embodiment, the feed path 120 may be disposed with a downward inclination to facilitate the feed of the aqueous solution 110. Other suitable arrangements are also contemplated to suit the application.
The high-frequency power supply unit 128 generates and passes a high-frequency current enough to increase the temperature of the metal pipe 124 to a predetermined treatment temperature, e.g., 100-350° C., for the aqueous solution 110 to be treated using the heating induction coils 126. An exemplary energization frequency of the high-frequency power supply unit 128 can be approximately 20 kilohertz (KHz) and a maximum output can be approximately 270 kilowatts (KW). However, the frequency and the maximum output of the high-frequency power supply unit 128 can vary to suit different applications.
Exemplary arrangements of the metal pipes 124 in the induction heating assembly 102 can be in a horizontal, vertical, or diagonal attitude to suit different applications. However, the diagonal attitude can be selected in consideration of a type of particles 112 and/or the feed of the aqueous solution 110.
In the illustrated embodiment, a control system 154 is communicably connected to the induction heating assembly 102 via a communication link 156. In one embodiment, the control system 154 includes computer readable program instructions stored in one of memories of electronic controllers in the control system 154 and executed by a respective processor of the electronic controllers, or other computer usable medium. In another embodiment, the control system 154 includes a module or controller, which may or may not be independent from one of the electronic controllers of the decomposing system 100.
In
As a continuous flow path for the treated product 114, the first outlet 18 and the second outlet 20 of the backpressure regulator assembly 12 are communicating with and fluidically connected to the treated object retrieving zone 108. In this configuration, the pressurized treated product 114 received from the discharge end 158 of the metal pipes 124 in the induction heating assembly 102 passes through the backpressure regulator assembly 12 at a constant flow rate. As such, the treated product 114 is continuously delivered to and stored in the treated object retrieving zone 108 without interruption.
Various automated operations of the backpressure regulator assembly 12 are achieved by the controller 14. In the illustrated embodiment, the controller 14 is communicably connected to the backpressure regulator assembly 12 via a communication link 22. In embodiments, the communication link 22 can include a wired and/or wireless data transmission interface. Detailed components of the backpressure regulator assembly 12 are described in paragraphs relating to

In one embodiment, a first end 28 of TANK124 is fluidically connected to the inlet 16 of the backpressure regulator assembly 12 and an opposite second end 30 of TANK124 is fluidically connected to an air supply assembly 32. Similarly, a first end 34 of TANK226 is fluidically connected to the inlet 16 of the backpressure regulator assembly 12 and an opposite second end 36 of TANK226 is fluidically connected to the air supply assembly 32.
In this illustrated embodiment, the air supply assembly 32 is configured to provide air pressure for both TANK124 and TANK226. In another embodiment, separate air supply assemblies can be used to independently provide the air pressure for TANK124 and TANK226. To selectively control the air pressure, a first air supply valve 38 and a first air discharge valve 40 are connected to the second end 30 of TANK124.
Similarly, a second air supply valve 42 and a second air discharge valve 44 are connected to the second end of 36 of TANK226. In one embodiment, the first air supply valve 38, the first air discharge valve 40, the second air supply valve 42, and the second air discharge valve 44 are operated by respective actuators 45, such as solenoids.
During operation, however, one or more bursting incidents in TANK124 (or TANK226) can occur due to the treated product 114 discharged from the inlet 16 at the high pressure. Thus, partial or full opening and closing operations of the first air supply valve 38 and the first air discharge valve 40 are desired to maintain a certain level of air pressure in TANK124.
To provide a smooth flow of the treated product 114 into TANK124, the controller 14 can control the air pressure in TANK124 by selectively performing such opening and closing operations. Similarly, the controller 14 can control the opening and closing operations of the second air supply valve 42 and the second air discharge valve 44.
A first pressure sensor 46 configured to measure an inner pressure of TANK124 is operably connected upstream from the first end 28 of TANK124. Similarly, a second pressure sensor 48 configured to measure an inner pressure of TANK226 is operably connected upstream from the first end 34 of TANK226. In another embodiment, the first pressure sensor 46 can be operably connected near the second end 30 of TANK124 or directly to a housing of TANK124 to suit the application. The second pressure sensor 48 can also be arranged in the similar fashion as the first pressure sensor 46. Any number of pressure sensors disposed on any suitable locations is contemplated to suit different applications.

In one embodiment, an output flow rate of the treated product 114 is adjusted by the first discharge valve actuator 56 using, for example, a knife or slide gate valve.
Likewise, for facilitating an intake of the treated product 114 into TANK226, a second slurry supply valve 58 operated by a second supply valve actuator 60 is connected at one end to the inlet 16 and at the other end to the first end 34 of TANK226. In one embodiment, an intake flow rate of the treated product 114 is adjusted by the second supply valve actuator 58 using, for example, a knife or slide gate valve.
For facilitating an output of the treated product 114 from TANK226, a second slurry discharge valve 62 operated by a second discharge valve actuator 64 is connected to the first end 34 of TANK226. In one embodiment, an output flow rate of the treated product 114 is adjusted by the second discharge valve actuator 64 using, for example, a knife or slide gate valve.
A first liquid level sensor 66 configured to measure a level of the treated product 114 in TANK124 is operably connected near the second end 30 of TANK124. Similarly, a second liquid level sensor 68 configured to measure a level of the treated product 114 in TANK226 is operably connected near the second end 36 of TANK226. In one embodiment, the first liquid level sensor 66 measures in real time a current level of the treated product 114 stored in TANK124 for monitoring purposes. Similarly, the second liquid level sensor 68 measures in real time a current level of the treated product 114 stored in TANK226.

In another embodiment, the controller 14 includes a module or controller, which may or may not be independent from one of the electronic controllers of the pressure regulation system 10. For example, the controller 14 can be a programmable logic controller (PLC) or programmable controller.
In one embodiment, the controller 14 automatically controls the opening and closing operations of the first air supply valve 38 and the first air discharge valve 40 by instructing the respective actuators 45 using the computer readable program instructions. Further, the controller 14 automatically controls the opening and closing operations of the second air supply valve 42 and the second air discharge valve 44 by instructing the respective actuators 45 using the computer readable program instructions.
In embodiments, the controller 14 automatically controls the opening and closing operations of the first slurry supply valve 50 by instructing the first supply valve actuator 52 using the computer readable program instructions.

In embodiments, the method 200 can be implemented by the controller 14 (
In another embodiment, the steps implementing the method 200 may be stored and executed on a module or a control system, which may or may not be independent from one of the electronic controllers of the pressure regulation system 10. The method 200 may run continuously or may be initiated in response to one or more predetermined events, such as an initial push of a start button (not shown). Any steps of the method 200 can be executed in any order suitable for the application.
The method 200 begins in step 202. In step 204, the controller 14 instructs the respective actuators 45 to transition TANK124 and TANK226 into a pressurized state. In embodiments, the controller 14 instructs the respective actuators 45 to open the first air supply valve 38 and the second air supply valve 42 for receiving compressed air into TANK124 and TANK226. Thus, TANK124 and TANK226 are pressurized to a predetermined pressure level, e.g., one megapascal (1 MPa), to approximately match a pressure level of the inlet 16. In embodiments, the pressure levels are measured using the respective first and second pressure sensors 46 and 48.
In some embodiments, the predetermined pressure level can be 0.93 MPa depending on a power capability of the air supply assembly 32. As such, the controller 14 instructs the air supply assembly 32 to deliver sufficient compressed air into TANK124 and TANK226 to pressurize and reach the predetermined pressure level.
In step 206, the controller 14 instructs the respective actuators 45 to close the first air supply valve 38 and/or the second air supply valve 42 for TANK124 and TANK226 when the predetermined pressure level is obtained in the respective reservoirs, i.e., TANK124 and TANK226. At this moment, TANK124 and TANK226 are ready to receive the treated product 114 from the inlet 16 of the backpressure regulator assembly 12.
In step 208, the controller 14 instructs the first supply valve actuator 52 to open the first slurry supply valve 50 for receiving the treated product 114 from the inlet 16. As such, the treated product 114 is continuously delivered to TANK124 until the level of the treated product 114 in TANK124 reaches a predetermined level (e.g., eighty percent (80%) full).
In step 210, the controller 14 determines whether a current level of the treated product 114 delivered into TANK124 is greater than a predetermined level LEVEL1 using the first liquid level sensor 66. When the current level of the treated product 114 in TANK124 is greater than the predetermined level LEVEL1, control proceeds to step 212 and step 226.
It is advantageous that although the intake of the treated product 114 into TANK124 is discontinued in step 212, the intake of the treated product 114 into TANK226 continues in step 226. As such, the discharge flow of the treated product 114 is continuous and uninterrupted. When the current level of the treated product 114 in TANK124 is less than or equal to the predetermined level LEVEL1, control returns to step 208.
In step 212, the controller 14 instructs the first supply valve actuator 52 to close the first slurry supply valve 50 for discontinuing the feed of the treated product 114 from the inlet 16.
In step 214, the controller 14 instructs the respective actuator 45 to transition TANK124 into an unpressurized state. In embodiments, the controller 14 instructs the respective actuator 45 to open the first air discharge valve 40 for equalizing TANK124 with atmospheric pressure. In some embodiments, the inner pressure of TANK124 is approximately 0.00 MPa. At this moment, TANK124 is transitioned into the unpressurized state and ready to discharge the treated product 114 from the first outlet 18 of the backpressure regulator assembly 12.
In step 216, the controller 14 instructs the first discharge valve actuator 56 to open the first slurry discharge valve 54 for facilitating the discharge of the treated product 114 from TANK124 through the first outlet 18. In this configuration, the discharge of the treated product 114 from TANK124 is achieved under the action of gravity since the inner pressure of TANK124 is equalized with the atmosphere pressure.
In step 218, the controller 14 instructs the first discharge valve actuator 56 to close the first slurry discharge valve 54 for discontinuing the discharge of the treated product 114 from the first outlet 18. In one embodiment, the first slurry discharge valve 54 is closed when TANK124 is empty.
In step 220, the controller 14 instructs the respective actuator 45 to transition TANK1 into the pressurized state. In embodiments, the controller 14 instructs the respective actuator 45 to close the first air discharge valve 40 to transition TANK124 into the pressurized state.
In step 222, the controller 14 instructs the respective actuator 45 to open the first air supply valve 38 for receiving compressed air into TANK124. As a result, TANK124 is pressurized to the predetermined pressure level (e.g., 1 MPa) to approximately match the pressure level of the inlet 16.
In step 224, the controller 14 instructs the respective actuator 45 to close the first air supply valve 38 for TANK124 when the predetermined pressure level is obtained in TANK124. At this moment, TANK124 is transitioned into the pressurized state and ready to receive the treated product 114 from the inlet 16 of the backpressure regulator assembly 12.
In step 226, the controller 14 instructs the second supply valve actuator 60 to open the second slurry supply valve 58 for receiving the treated product 114 from the inlet 16. As such, the treated product 114 is continuously delivered to TANK226 until the level of the treated product 114 in TANK226 reaches a predetermined level (e.g., eighty percent (80%) full).
In step 228, the controller 14 determines whether a current level of the treated product 114 delivered into TANK226 is greater than a predetermined level LEVEL2 using the second liquid level sensor 68. When the current level of the treated product 114 in TANK226 is greater than the predetermined level LEVEL2, control proceeds to step 230 and step 208.
It is advantageous that although the intake of the treated product 114 into TANK226 is discontinued in step 230, the intake of the treated product 114 into TANK124 continues in step 208. As such, the discharge flow of the treated product 114 is continuous and uninterrupted. When the current level of the treated product 114 in TANK226 is less than or equal to the predetermined level LEVEL2, control returns to step 226.
In step 230, the controller 14 instructs the second supply valve actuator 60 to close the second slurry supply valve 58 for discontinuing the feed of the treated product 114 from the inlet 16.
In step 232, the controller 14 instructs the respective actuator 45 to transition TANK226 into an unpressurized state. In embodiments, the controller 14 instructs the respective actuator 45 to open the second air discharge valve 44 for equalizing TANK226 with atmospheric pressure. In some embodiments, the inner pressure of TANK226 is approximately 0.00 MPa. At this moment, TANK226 is transitioned into the unpressurized state and ready to discharge the treated product 114 from the second outlet 20 of the backpressure regulator assembly 12.
In step 234, the controller 14 instructs the second discharge valve actuator 64 to open the second slurry discharge valve 62 for facilitating the discharge of the treated product 114 from TANK226 through the second outlet 20. In this configuration, the discharge of the treated product 114 from TANK226 is achieved under the action of gravity since the inner pressure of TANK226 is equalized with the atmosphere pressure.
In step 236, the controller 14 instructs the second discharge valve actuator 64 to close the second slurry discharge valve 62 for discontinuing the discharge of the treated product 114 from the second outlet 20. In one embodiment, the second slurry discharge valve 62 is closed when TANK226 is empty.
In step 238, the controller 14 instructs the respective actuator 45 to transition TANK2 into the pressurized state. In embodiments, the controller 14 instructs the respective actuator 45 to close the second air discharge valve 44 to transition TANK226 into the pressurized state.
In step 240, the controller 14 instructs the respective actuator 45 to open the second air supply valve 42 for receiving compressed air into TANK226. As a result, TANK226 is pressurized to the predetermined pressure level (e.g., 1 MPa) to approximately match the pressure level of the inlet 16.
In step 242, the controller 14 instructs the respective actuator 45 to close the second air supply valve 42 for TANK226 when the predetermined pressure level is obtained in TANK226. At this moment, TANK226 is transitioned into the pressurized state and ready to receive the treated product 114 from the inlet 16 of the backpressure regulator assembly 12.
The method 200 may end in step 242 and/or control may return to step 202. One or more of steps 204-242 can be repeated as desired to suit the application.
It should be appreciated that any steps of the method 200 described herein may be implemented by a process controller, or other similar component, of the controller 14. Specifically, the process controller may be configured to execute computer readable instructions for performing one or more steps of the method 200. In one embodiment, the process controller may also be configured to transition from an operating state, during which a larger number of operations are performed, to a sleep state, in which a limited number of operations are performed, thus further reducing quiescent power draw of an electrical power source for the pressure regulation system 10.
