Description

Technical Field

[0001] This invention relates to the field of exhaust gas treatment technology, and in particular to a carbon dioxide expansion purification system, method, electronic device, and storage medium. Background Technology

[0002] The principle of carbon dioxide expansion involves impregnating dried tobacco shreds with liquid carbon dioxide at a specific temperature and pressure for a certain period in a cold terminal system. This allows the carbon dioxide to fully penetrate the tobacco shreds. Then, the pressure is reduced, causing the liquid carbon dioxide in the tobacco shreds to transform into solid carbon dioxide. This impregnation process generates cold-end exhaust gas. The tobacco shreds are then transferred to a hot terminal system, where a high-temperature airflow briefly contacts the tobacco shreds. Due to the sublimation of carbon dioxide, the tobacco shreds rapidly expand in volume, thereby increasing their filling capacity.

[0003] During the carbon dioxide expansion production process, to facilitate staff monitoring of the cold terminal system equipment, residual carbon dioxide fumes are vented from the system during tobacco impregnation. Currently, the residual carbon dioxide is directly released into the atmosphere. However, because the emitted carbon dioxide has been used to impurity the tobacco, it contains tobacco-related odors. With increasing environmental regulations and the need to minimize odor impact on the surrounding environment, this residual carbon dioxide needs to be treated.

[0004] Because carbon dioxide expansion production equipment includes specialized equipment such as high-pressure cryogenic pressure vessels and high-temperature combustion furnaces, its control network is not connected to the outside world and operates independently. Furthermore, the generation of cold-end exhaust gas during the carbon dioxide expansion production process involves a cyclical process; it does not require continuous treatment but rather needs to be processed at intervals. Therefore, efficient purification of the cold-end exhaust gas is necessary. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] The following is combined with Figures 1-5 The present invention describes a carbon dioxide expansion purification system, method, electronic device, and storage medium.

[0036] Specifically, the present invention provides a carbon dioxide expansion purification system, referring to... Figure 1 , Figure 1 This is a schematic diagram of the carbon dioxide expansion purification system provided by the present invention.

[0037] An embodiment of the present invention provides a carbon dioxide expansion purification system, comprising: a cold terminal system, a hot terminal system, an exhaust gas treatment subsystem, a communication component, a first fan connected to the cold terminal system, and a second fan connected to the exhaust gas treatment subsystem;

[0038] The cold terminal system is connected to the hot terminal system and the exhaust gas treatment subsystem respectively. The hot terminal system communicates with the exhaust gas treatment subsystem through a communication component.

[0039] The cold terminal system is used to control the operation of the first fan to discharge the cold terminal exhaust gas to the exhaust gas treatment subsystem and to send the control signal of the first fan to the hot terminal system.

[0040] The hot terminal system is used to receive control signals sent by the cold terminal system and send the control signals to the exhaust gas treatment subsystem through the communication component.

[0041] The exhaust gas treatment subsystem is used to receive control signals sent by the hot end terminal system through the communication component, and control the operation of the second fan based on the control signals to purify the cold end exhaust gas.

[0042] It should be noted that in the tobacco industry, the cold terminal system mainly consists of equipment such as impregnators, process tanks, compressors, refrigeration units, pumps, and pipeline valves; while the hot terminal system mainly consists of equipment such as reciprocating belt conveyors, storage belts, openers, limiting tubes, metering belts, feed air locks, sublimators, discharge air locks, tangential separators, cooling belt conveyors, and combustion furnaces.

[0043] In the process of using carbon dioxide expanded tobacco, liquid carbon dioxide is used to impregnate the tobacco in the impregnator of the cold end system. Cold end exhaust gas is generated during the impregnation process. This cold end exhaust gas is extracted by a first fan and sent to the exhaust gas treatment subsystem for purification. The cold end exhaust gas contains excess carbon dioxide and impurities, including gases generated during the impregnation process.

[0044] The hot-end terminal system is used to receive and forward control signals from the first fan. It also expands the impregnated tobacco, generating some smoke during the expansion process. This smoke is burned in a furnace within the hot-end terminal system to remove combustible materials and produce hot-end exhaust gas. This hot-end exhaust gas is ultimately sent to the exhaust gas treatment subsystem for purification. For example, the hot-end exhaust gas is purified by the HQ17 exhaust gas purification system within the exhaust gas treatment subsystem. The exhaust gas treatment subsystem includes the HQ14 and HQ17 exhaust gas purification systems. The HQ14 system purifies the exhaust gas discharged from the HDT (High-Temperature Dryer) airflow dryer and the cold-end exhaust gas, while the HQ17 system purifies the hot-end exhaust gas.

[0045] One end of the communication component is connected to the hot terminal system, and the other end is connected to the exhaust gas treatment subsystem, thereby realizing the communication connection between the hot terminal system and the exhaust gas treatment subsystem. The communication component is used to receive the control signal of the first fan and forward the control signal of the first fan to the exhaust gas treatment subsystem, so that the exhaust gas treatment subsystem controls the operation of the second fan based on the control signal. The first fan can be an exhaust fan, used to transport cold-end exhaust gas from the cold terminal system to the exhaust gas treatment subsystem; the second fan can be a cleaning fan, used to assist the exhaust gas treatment subsystem in purifying the cold-end exhaust gas.

[0046] When the cold terminal system needs to discharge cold-end exhaust gas, it generates a control signal for the first fan to start it. The first fan extracts the cold-end exhaust gas from the cold terminal system and transmits it to the HQ14 exhaust gas purification system in the exhaust gas treatment subsystem via a transmission pipeline. Simultaneously, the cold terminal system sends the control signal for the first fan to the hot terminal system via the network cabinet. Upon receiving the control signal, the hot terminal system transmits it to the exhaust gas treatment subsystem via a communication component. The exhaust gas treatment subsystem receives the control signal and, based on this signal, controls the second fan in the HQ14 exhaust gas purification system to operate, thereby activating the HQ14 exhaust gas purification system to purify the cold-end exhaust gas. Further, the hot terminal system discharges hot-end exhaust gas, which is then transmitted via a transmission pipeline to the HQ17 exhaust gas purification system for further purification.

[0047] Optional, such as Figure 2 As shown, one end of the communication component connects to the cold terminal system, and the other end connects to the exhaust gas treatment subsystem, thus realizing the communication connection between the cold terminal system and the exhaust gas treatment subsystem. When the cold terminal system needs to discharge cold-end exhaust gas, it generates a control signal for the first fan to start the first fan. The first fan extracts the cold-end exhaust gas from the cold terminal system and inputs it into the HQ14 exhaust gas purification system in the exhaust gas treatment subsystem through the transmission pipeline. Simultaneously, the cold terminal system sends the control signal of the first fan to the exhaust gas treatment subsystem through the communication component. The exhaust gas treatment subsystem receives the control signal and, based on the control signal, controls the operation of the second fan in the HQ14 exhaust gas purification system, thereby starting the HQ14 exhaust gas purification system to purify the cold-end exhaust gas.

[0048] The carbon dioxide expansion purification system provided in this invention includes a cold terminal system, a hot terminal system, an exhaust gas treatment subsystem, a communication component, a first fan connected to the cold terminal system, and a second fan connected to the exhaust gas treatment subsystem. The cold terminal system is connected to both the hot terminal system and the exhaust gas treatment subsystem. The hot terminal system communicates with the exhaust gas treatment subsystem via the communication component. The cold terminal system controls the operation of the first fan to discharge cold-end exhaust gas to the exhaust gas treatment subsystem and sends control signals from the first fan to the hot terminal system. The hot terminal system receives control signals from the cold terminal system and sends these control signals to the exhaust gas treatment subsystem via the communication component. The exhaust gas treatment subsystem receives control signals from the hot terminal system via the communication component and controls the operation of the second fan based on these control signals to purify the cold-end exhaust gas. This invention uses the communication component to send control signals from the first fan in the cold terminal system to the exhaust gas treatment subsystem, which then controls the operation of the second fan based on these control signals to purify the cold-end exhaust gas, thereby improving the efficiency of exhaust gas purification.

[0049] Based on the above embodiments, the cold terminal system is communicatively connected to the exhaust gas treatment subsystem via a communication component;

[0050] The cold terminal system is also used to send the control signal of the first fan to the exhaust gas treatment subsystem;

[0051] The exhaust gas treatment subsystem is also used to receive control signals sent by the cold terminal system through the communication component, and control the operation of the second fan based on the control signals to purify the cold terminal exhaust gas.

[0052] like Figure 3 As shown, one end of the communication component is connected to both the cold terminal system and the hot terminal system, and the other end is connected to the exhaust gas treatment subsystem, thereby realizing the communication connection between the cold terminal system, the hot terminal system and the exhaust gas treatment subsystem.

[0053] When the cold terminal system needs to discharge cold-end exhaust gas, it generates a control signal for the first fan to start it. The first fan extracts the cold-end exhaust gas from the cold terminal system and inputs it into the HQ14 exhaust gas purification system within the exhaust gas treatment subsystem via a transmission pipeline. Simultaneously, the cold terminal system sends the control signal for the first fan to the exhaust gas treatment subsystem via a communication component. The exhaust gas treatment subsystem receives the control signal and, based on this signal, controls the operation of the second fan in the HQ14 exhaust gas purification system, thereby activating the HQ14 exhaust gas purification system to purify the cold-end exhaust gas.

[0054] Optionally, while controlling the start of the first fan, the cold terminal system sends the control signal of the first fan to the hot terminal system via the network cabinet. After receiving the control signal, the hot terminal system sends the control signal to the exhaust gas treatment subsystem via the communication component. The exhaust gas treatment subsystem receives the control signal and, based on the control signal, controls the operation of the second fan in the HQ14 exhaust gas purification system, thereby starting the HQ14 exhaust gas purification system to purify the cold terminal exhaust gas.

[0055] In this embodiment of the invention, a communication component is used to connect the cold terminal system and the exhaust gas treatment subsystem, which facilitates the cold terminal system to directly send the control signal of the first fan to the exhaust gas treatment subsystem, thereby improving the purification of the cold terminal exhaust gas.

[0056] Based on the above embodiments, the exhaust gas treatment subsystem includes a purification device, which works in conjunction with a second fan to purify the cold-end exhaust gas.

[0057] Purification equipment is used to purify carbon dioxide and other gases in cold-end exhaust gas. It generally includes water washing equipment, acid washing equipment, alkali washing equipment, filtration equipment, catalytic reaction equipment, etc.

[0058] The second fan is used to promote the transmission of cold-end exhaust gas in the purification equipment, so that the purification equipment can purify the cold-end exhaust gas.

[0059] This invention provides a solution for purifying cold-end exhaust gas by installing a purification device in the exhaust gas treatment subsystem, thereby avoiding pollution caused by directly discharging the cold-end exhaust gas into the atmosphere.

[0060] Based on the above embodiments, the purification equipment includes a spray tower, which is used to spray water onto the cold end exhaust gas to clean it; and a second fan is used to extract the cleaned cold end exhaust gas to the outside.

[0061] During the cleaning process, most of the excess carbon dioxide in the cold-end exhaust gas dissolves in water, thus greatly reducing the emission of carbon dioxide in the cold-end exhaust gas.

[0062] The impurities in the cold-end exhaust gas originate from tobacco shreds, and most of these impurities are water-soluble organic gases. By washing the cold-end exhaust gas with water using a spray tower, most of these impurities can be dissolved, thereby reducing their emission.

[0063] For example, the cold-end exhaust gas moves from end B to end A, the spray tower sprays water from end A to end B, and the second fan operates to draw away the cold-end exhaust gas from end A, thereby accelerating the movement of the cold-end exhaust gas from end B to end A. The counter-current movement of the cold-end exhaust gas and water increases the contact area between the cold-end exhaust gas and water, thus improving the cleaning degree of the cold-end exhaust gas.

[0064] In this embodiment of the invention, the cold-end exhaust gas is washed with water using a spray tower, which can purify most of the carbon dioxide and impurities in the cold-end exhaust gas. The second fan makes the cold-end exhaust gas flow in reverse in the spray water, which improves the cleaning degree of the cold-end exhaust gas by the spray tower.

[0065] Based on the above embodiments, a network cabinet is also included, which is connected to both the cold terminal system and the hot terminal system.

[0066] A network cabinet is used to forward interactive data between cold terminal systems and hot terminal systems, or to control cold terminal systems and hot terminal systems.

[0067] During the carbon dioxide expansion process, the cold terminal system soaks the tobacco in carbon dioxide, and the soaked carbon dioxide is then transferred to the hot terminal system for expansion.

[0068] In this embodiment of the invention, the cold terminal system and the hot terminal system are connected by a network cabinet, which facilitates data communication between the cold terminal system and the hot terminal system, thereby making the connection of the exhaust gas treatment process of the cold terminal system and the hot terminal system more flexible and efficient.

[0069] Furthermore, the network cabinet can control the cold terminal system and the hot terminal system, thereby controlling the exhaust gas treatment process and exhaust gas treatment efficiency of the cold terminal system and the hot terminal system.

[0070] In this embodiment of the invention, the cold terminal system and the hot terminal system are connected by a network cabinet, which improves the efficiency of cold terminal exhaust gas purification.

[0071] Based on the above embodiments, the communication component is a coupler used to receive and forward control signals from the first wind turbine. The coupler can be a PN / PN coupler, used to connect two Ethernet communication system (Profinet) networks and exchange data, with a maximum exchange capacity of 1024 bytes. Data exchange uses two corresponding buffers, each with a sending area (Output) and a receiving area (Input). The sending area of ​​one Profinet network corresponds to the receiving area of ​​another Profinet network, and vice versa. The sending and receiving areas need to be configured using configuration tools. Profinet is based on 100Mbps Ethernet, forming a network between the controller (PLC) and distributed terminals (IO).

[0072] This invention improves the purification efficiency of cold-end exhaust gas by setting the coupler as a communication component, while ensuring the network security of the system.

[0073] Based on the above embodiments, a transmission pipeline is also included, which is connected to the cold terminal system and the exhaust gas treatment subsystem respectively.

[0074] Transmission lines are used to transmit cold-end exhaust gas, for example, to transmit cold-end exhaust gas from the cold-end terminal system to the exhaust gas treatment subsystem.

[0075] Untreated cold-end exhaust gas must not leak into the atmosphere. A dedicated transmission pipeline is required to transport the cold-end exhaust gas. This pipeline also fixes the transmission path of the cold-end exhaust gas, preventing unnecessary path travel and accelerating its transmission rate.

[0076] This invention embodiment uses a transmission pipeline to transmit cold-end exhaust gas, thereby accelerating the transmission rate of the cold-end exhaust gas and improving the purification efficiency of the cold-end exhaust gas.

[0077] like Figure 4 As shown, this embodiment of the invention also provides a method for exhaust gas purification, applied to the above-mentioned carbon dioxide expansion purification system, comprising:

[0078] S100, send a control signal to the first fan, wherein the first fan operates based on the received control signal to discharge the cold end exhaust gas to the exhaust gas treatment subsystem through the transmission pipeline;

[0079] S200 sends control signals to the exhaust gas treatment subsystem via a communication component. The exhaust gas treatment subsystem controls the operation of the second fan based on the received control signals, so as to purify the cold-end exhaust gas discharged from the transmission pipeline through the purification equipment and the second fan.

[0080] When the cold terminal system needs to discharge cold terminal exhaust gas, the cold terminal system sends a control signal to the first fan to control the operation of the first fan and the operating speed of the first fan. The first fan extracts the cold terminal exhaust gas from the cold terminal system and transmits the cold terminal exhaust gas to the HQ14 exhaust gas purification system in the exhaust gas treatment subsystem through the transmission pipeline.

[0081] While the cold terminal system sends a control signal to the first fan, it also sends the control signal for the first fan to the hot terminal system via the network cabinet. The hot terminal system then sends the control signal to the exhaust gas treatment subsystem via the communication component. Upon receiving the control signal, the exhaust gas treatment subsystem starts the operation of the second fan in the HQ14 exhaust gas purification system and determines its operating speed based on the control signal.

[0082] The exhaust gas treatment subsystem starts the second fan in the HQ14 exhaust gas purification system simultaneously with the start of the spray tower (purification equipment) within the HQ14 exhaust gas purification system. The spray tower sprays water from end A to end B, while the cold-end exhaust gas moves from end B to end A. The second fan draws away the cold-end exhaust gas from end A, thereby accelerating its movement from end B to end A. This ensures that carbon dioxide and impurities in the cold-end exhaust gas are fully dissolved in the water, thus purifying the cold-end exhaust gas.

[0083] The exhaust gas purification method provided in this embodiment of the invention includes: sending a control signal to a first fan, wherein the first fan operates based on the received control signal to discharge cold-end exhaust gas through a transmission pipeline to an exhaust gas treatment subsystem; and sending the control signal to the exhaust gas treatment subsystem via a communication component, wherein the exhaust gas treatment subsystem controls a second fan to operate based on the received control signal, so as to purify the cold-end exhaust gas discharged through the transmission pipeline through the purification equipment and the second fan. The exhaust gas purification method provided in this embodiment of the invention achieves exhaust gas purification by simultaneously sending a control signal to the first fan and then sending the control signal to the exhaust gas treatment device via a communication component, thereby simultaneously activating the second fan.

Figure 5As shown, the electronic device may include: a processor 510, a communication interface 520, a memory 530, and a communication bus 540, wherein the processor 510, the communication interface 520, and the memory 530 communicate with each other via the communication bus 540. The processor 510 can call logical instructions in the memory 530 to execute the above-mentioned exhaust gas purification method, which includes:

[0085] A control signal is sent to the first fan, which operates based on the received control signal to discharge the cold end exhaust gas to the exhaust gas treatment subsystem through the transmission pipeline;

[0086] The control signal is sent to the exhaust gas treatment subsystem via the communication component. Based on the received control signal, the exhaust gas treatment subsystem controls the operation of the second fan to purify the cold-end exhaust gas discharged from the transmission pipeline through the purification equipment and the second fan.

[0087] Furthermore, the logical instructions in the aforementioned memory 530 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product.

The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

[0088] On the other hand, the present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, is implemented to perform the above-described exhaust gas purification method, the method comprising:

[0089] A control signal is sent to the first fan, which operates based on the received control signal to discharge the cold end exhaust gas to the exhaust gas treatment subsystem through the transmission pipeline;

[0090] The control signal is sent to the exhaust gas treatment subsystem via the communication component. Based on the received control signal, the exhaust gas treatment subsystem controls the operation of the second fan to purify the cold-end exhaust gas discharged from the transmission pipeline through the purification equipment and the second fan.
