Description

Technical Field

[0001] This invention relates to the field of deodorization technology in tobacco wastewater treatment areas, and particularly to a deodorization sealing system and control method for a tobacco wastewater treatment station. Background Technology

[0002] Industrial wastewater generated during tobacco production is characterized by its complex composition, high pollutant concentration, and prominent characteristic malodor. It contains not only conventional organic matter and ammonia nitrogen, but also a large amount of volatile and semi-volatile organic compounds derived from tobacco raw materials, such as nicotine, various sugars, pectin, cellulose, and flavorings, organic acid esters, and alcohols added during production. These characteristic pollutants, through microbial decomposition and physical agitation in the wastewater treatment plant's screens, equalization tanks, anaerobic, aerobic, and sludge treatment units, release complex and highly irritating mixed malodorous gases. This odor has a low threshold, strong sensory stimulation, and some components are difficult to completely degrade using traditional deodorization processes.

[0003] Currently, tobacco industry wastewater treatment plants typically only implement localized, sealed ventilation for a few key tanks or provide preliminary overall covering for the treatment line to collect such high-intensity, complex odorous gases. However, these methods, which only cover individual tanks or provide overall ventilation, fail to scientifically zone the wastewater based on odor concentration and equipment operating conditions, and thus cannot effectively curb the spread of odors. Summary of the Invention

By scientifically dividing the tobacco wastewater treatment plant into zones, the system precisely controls the ventilation volume according to the odor concentration and equipment status of each zone, thereby achieving precise air supply to different zones, curbing odor diffusion, improving the odor sealing and collection effect, and reducing the system's operating energy consumption.

[0021] Figure 1 This is a schematic diagram of a deodorization and sealing system for a tobacco wastewater treatment plant according to an embodiment of the present invention. This embodiment is applicable to situations where odors from a tobacco wastewater treatment plant are collected and sealed in separate zones to suppress odor diffusion. Figure 1As shown, the deodorization and sealing system of the tobacco wastewater treatment plant includes a zoned sealing collection module 10, an exhaust module 20, a control module 30, and multiple monitoring modules 40. The zoned sealing collection module 10 is used to collect primary odors emitted from the raw tobacco wastewater after treatment in the impact volatilization zone 100, secondary odors generated from the raw tobacco wastewater after metabolic fermentation in the biological metabolism zone 200, and tertiary odors generated from the raw tobacco wastewater after sedimentation in the sludge treatment zone 300. The concentrations of primary and secondary odors are both lower than the concentration of tertiary odors. Multiple monitoring modules 40 are respectively installed in the impact volatilization zone 100, the biological metabolism zone 200, and the sludge treatment zone 300 to monitor the odor concentration and the status of the treatment equipment in the corresponding zones. The control module 30 is electrically connected to the monitoring module 40 and the exhaust module 20 to receive the odor concentration and the status of the treatment equipment, and adjusts the exhaust volume of the exhaust module 20 according to the odor concentration and the status of the treatment equipment. The exhaust volume of each zone is positively correlated with the odor concentration of that zone.

[0022] In this embodiment, the deodorization and sealing system for the tobacco wastewater treatment plant includes a zoned sealing and collection module 10, an exhaust module 20, a control module 30, and multiple monitoring modules 40. The zoned sealing and collection module 10 can be understood as an integrated module that divides the tobacco wastewater treatment plant into different zones based on the process flow and odor release characteristics, and performs sealed collection of odors released from the wastewater treatment equipment in each zone. The zoned sealing and collection module 10 is equipped with corresponding collection pipelines according to the odor concentration and type of treatment equipment in each zone, achieving precise, zoned, and efficient sealed collection of odors from different zones.

[0023] Specifically, based on the process flow and odor release characteristics of the tobacco wastewater treatment plant, the plant is divided into an impact volatilization zone 100, a biological metabolism zone 200, and a sludge treatment zone 300. The impact volatilization zone 100 includes the equalization tank and flotation tank, used to receive raw tobacco wastewater. The raw tobacco wastewater experiences significant water quality fluctuations under flotation treatment, easily releasing primary odor containing organic matter. A zoned sealed collection module 10 collects the primary odor emitted from the raw tobacco wastewater after treatment in the impact volatilization zone 100. The biological metabolism zone 200 mainly includes anaerobic tanks, anoxic tanks, aerobic tanks, and a membrane bioreactor (MBR) tank. The raw tobacco wastewater undergoes microbial metabolism and fermentation in the anaerobic, anoxic, and aerobic tanks, producing metabolic sludge and secondary odor containing sulfides, ammonia, or small-molecule organic matter. The zoned sealed collection module 10 collects the secondary odor produced by the raw tobacco wastewater after metabolic fermentation in the biological metabolism zone 200. The sludge treatment area 300 includes a screen room and a sludge press. The sludge produced by the metabolic fermentation of tobacco wastewater in the biological metabolism area 200 is settled and filtered in the sludge treatment area 300, producing tertiary odor containing a large amount of sulfides and ammonia. The tertiary odor produced by the tobacco wastewater after sedimentation in the sludge treatment area 300 is collected by the zoned sealed collection module 10.

[0024] The concentrations of primary and secondary odors are both lower than those of tertiary odors, which have the highest concentration and contain large amounts of sulfides and ammonia. Therefore, the sludge treatment zone 300 can be designated as an area with high negative pressure protection and enhanced collection, relative to the shock volatilization zone 100 and the biological metabolism zone 200.

[0025] The exhaust module 20 can be understood as a power module capable of providing negative pressure to draw and transport odorous gases from each sealed area. Under the regulation of the control module 30, the exhaust module 20 can adjust the exhaust volume according to the odor concentration and equipment operating status of each area. For example, the exhaust module 20 includes, but is not limited to, an exhaust fan; this embodiment of the invention does not impose any limitations on this. The control module 30 can be understood as a control unit capable of receiving collected signals, performing calculations according to preset logic, and outputting control commands to relevant execution components. For example, the control module 30 includes, but is not limited to, a PLC controller. The monitoring module 40 can be understood as a module used to collect odor concentration signals and equipment status signals from each area of ​​the tobacco wastewater treatment station in real time, and transmit the collected odor concentration signals and equipment status signals to the monitoring component of the control module 30. For example, the monitoring module 40 includes, but is not limited to, sensors; this embodiment of the invention does not impose any limitations on this.

[0026] Specifically, multiple monitoring modules 40 are installed in the impact volatilization zone 100, the biological metabolism zone 200, and the sludge treatment zone 300, respectively. These monitoring modules 40 monitor the odor concentration and the status of the treatment equipment within their respective zones in real time. A control module 30 is electrically connected to both the monitoring modules 40 and the exhaust module 20. The control module 30 receives the odor concentration and equipment status data from the monitoring modules 40 and adjusts the exhaust module 20 accordingly, controlling its airflow. The status of the treatment equipment includes, but is not limited to, the open or closed state of the equipment doors within the corresponding zones.

[0027] The ventilation volume of each area is positively correlated with the odor concentration in that area. When the monitoring module 40 detects that the odor concentration in its area is greater than the preset range, the control module 30 controls the ventilation module 20 to increase the airflow, thereby strengthening the airflow in that area; when the monitoring module 40 detects that the odor concentration in its area is less than the preset range, the control module 30 controls the ventilation module 20 to decrease the airflow, thereby reducing ineffective air supply and lowering the operating energy consumption of the ventilation module 30.

[0028] For example, the monitoring module 40 monitors the concentration of tertiary odor in the sludge treatment area 300, the concentration of secondary odor in the biological metabolism area 200, and the concentration of primary odor in the shock volatilization area 100, and transmits the odor concentration signals of different areas to the control module 30. If the control module 30 detects that the concentration of tertiary odor is greater than the concentrations of secondary and primary odors, it controls the exhaust module 20 to deliver more air to the sludge treatment area 300 than the air to the biological metabolism area 200 and the shock volatilization area 100. When the monitoring module 40 detects an open signal from an equipment door in the sludge treatment area 300 and transmits this signal to the control module 30, and the control module 30 detects that the equipment door is open, it controls the exhaust module 20 to increase ventilation to prevent odor from overflowing and spreading from that area.

[0029] The deodorization and sealing system for a tobacco wastewater treatment plant provided in this embodiment of the invention collects primary odor from the raw tobacco wastewater after treatment in the impact volatilization zone 100, secondary odor from the raw tobacco wastewater after metabolic fermentation in the biological metabolism zone 200, and tertiary odor from the raw tobacco wastewater after sedimentation in the sludge treatment zone 300 by setting up a zone-specific sealing and collection module 10. The concentrations of primary and secondary odors are both lower than the concentration of tertiary odor. Multiple monitoring modules 40 are respectively installed in the impact volatilization zone 100, the biological metabolism zone 200, and the sludge treatment zone 300 to monitor the odor concentration and the status of the treatment equipment in the corresponding zones. A control module 30 is electrically connected to the monitoring modules 40 and the exhaust module 20. The control module 30 receives the odor concentration and the status of the treatment equipment and adjusts the exhaust volume of the exhaust module 20 according to the odor concentration and the status of the treatment equipment. The exhaust volume of each zone is positively correlated with the odor concentration of that zone. The tobacco wastewater treatment plant is scientifically zoned by dividing it into different areas based on odor emission concentration. The exhaust volume of the ventilation module 20 is precisely controlled based on the odor concentration and equipment status monitored by the monitoring module 40 within each area, achieving differentiated and precise air supply to each area and effectively curbing odor diffusion. This setup improves odor sealing and collection while reducing system energy consumption, solving the problems of insufficient odor collection intensity in high-concentration odor areas leading to odor diffusion and excessive exhaust volume in low-concentration odor areas resulting in significant energy waste.

[0030] Figure 2 This is a schematic diagram of another deodorization and sealing system for a tobacco wastewater treatment plant provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the deodorization and sealing system of the tobacco wastewater treatment station also includes multiple negative pressure collection modules 50, which are respectively located in the impact volatilization zone 100, the biological metabolism zone 200, and the sludge treatment zone 300. Each negative pressure collection module 50 includes a primary negative pressure collection unit 51, a secondary negative pressure collection unit 52, and a tertiary negative pressure collection unit 53. The diameter of the primary negative pressure collection unit 51 is larger than that of the secondary negative pressure collection unit 52, and the diameter of the secondary negative pressure collection unit 52 is larger than that of the tertiary negative pressure collection unit 53. The primary negative pressure collection unit 51 is connected to the exhaust module 20. The secondary negative pressure collection unit 52 is connected to the primary negative pressure collection unit 51 and the tertiary negative pressure collection unit 53. The tertiary negative pressure collection unit 53 is connected to the odor-releasing treatment equipment.

[0031] In this embodiment, the deodorization and sealing system of the tobacco wastewater treatment station further includes multiple negative pressure collection modules 50. Each negative pressure collection module 50 can be understood as a pipeline network structure that collects and transports odorous gases generated in each sealed area under negative pressure. It works in conjunction with the exhaust module 20 to create a negative pressure environment, enabling the directional transport of odorous gases to the collection units in each area. Exemplarily, the negative pressure collection module 50 includes, but is not limited to, a pipeline network structure composed of multiple pipes; this embodiment of the invention does not impose limitations on this. The negative pressure collection module 50 includes a primary negative pressure collection unit 51, a secondary negative pressure collection unit 52, and a tertiary negative pressure collection unit 53. These three units can be understood as three types of pipelines capable of supporting different levels of negative pressure. Exemplarily, the primary negative pressure collection unit 51 includes, but is not limited to, a main pipe; the secondary negative pressure collection unit 52 includes, but is not limited to, a branch pipe; and the tertiary negative pressure collection unit 53 includes, but is not limited to, a capillary tube.

[0032] Specifically, multiple primary negative pressure collection units 51, secondary negative pressure collection units 52, and tertiary negative pressure collection units 53 are installed in the impact volatilization zone 100, the biological metabolism zone 200, and the sludge treatment zone 300. The diameter of the primary negative pressure collection unit 51 is larger than that of the secondary negative pressure collection unit 52, and the diameter of the secondary negative pressure collection unit 52 is larger than that of the tertiary negative pressure collection unit 53. The primary negative pressure collection unit 51 is connected to the exhaust module 20 and is used to directly receive the exhaust air from the exhaust module 20, bearing the high negative pressure exhaust air volume. The secondary negative pressure collection unit 52 connects to the primary negative pressure collection unit 51 and the tertiary negative pressure collection unit 53, forming an airflow diversion branch, which transports the airflow from the primary negative pressure collection unit 51 to each tertiary negative pressure collection unit 53. The three-stage negative pressure collection unit 53 is connected to the odor-releasing treatment equipment. By receiving the air volume from the two-stage negative pressure collection unit 52, it concentrates the odor released by the treatment equipment into the corresponding zoned sealed collection module 10, thereby achieving sealed collection of the odor.

[0033] For example, in the impact evaporation zone 100, the air volume released from the exhaust module 20 is sequentially transmitted to the wastewater treatment equipment in the impact evaporation zone 100 through the first-level negative pressure collection unit 51, the second-level negative pressure collection unit 52 and the third-level negative pressure collection unit 53, so as to seal and collect the odor released by the wastewater treatment equipment in the impact evaporation zone 100 in the corresponding sub-area sealing collection module 10, thereby preventing the odor from overflowing and spreading in the wastewater treatment equipment.

[0034] The deodorization and sealing system for a tobacco wastewater treatment plant provided by this invention includes multiple primary negative pressure collection units 51, secondary negative pressure collection units 52, and tertiary negative pressure collection units 53, respectively, in the impact volatilization zone 100, the biological metabolism zone 200, and the sludge treatment zone 300. The diameter of the primary negative pressure collection unit 51 is larger than that of the secondary negative pressure collection unit 52, and the diameter of the secondary negative pressure collection unit 52 is larger than that of the tertiary negative pressure collection unit 53. The primary negative pressure collection unit 51 is directly connected to the exhaust module 20, the secondary negative pressure collection unit 52 is connected to both the primary and tertiary negative pressure collection units 51 and 53, and the tertiary negative pressure collection unit 53 is connected to the odor-releasing treatment equipment. This arrangement creates a directional negative pressure gradient in the tobacco wastewater treatment plant, causing a directional airflow from low-odor concentration areas to high-odor concentration areas. This guides the directional flow of odor, ensuring that the odor is efficiently and effectively sealed and collected in the corresponding zoned sealing collection modules 10, preventing odor diffusion and leakage, and improving the deodorization and sealing effect of the tobacco wastewater treatment plant. It solves the problem of disordered airflow, which makes it impossible to achieve directional flow and precise collection of odors.

[0035] Optional, you can continue to refer to Figure 2 The secondary negative pressure collection unit 52 includes an adjustment component 521, which is electrically connected to the control module 30. The control module 30 is used to adjust the opening of the adjustment component 521 according to the odor concentration of each area, so as to control the air volume entering the secondary negative pressure collection unit 52 of each area.

[0036] In this embodiment, the secondary negative pressure collection unit 52 includes an adjustment component 521. The adjustment component 521 can be understood as an actuator that can cooperate with the control module 30 to adjust the air volume in the negative pressure collection module 50. For example, the adjustment component 521 includes, but is not limited to, a regulating valve, and this embodiment of the invention does not impose any limitations on it.

[0037] Specifically, the regulating component 521 is electrically connected to the control module 30. The control module 30 outputs regulation commands based on the odor concentration in each area. The regulating component 521, based on the regulation commands output by the control module 30, precisely regulates the airflow in the secondary negative pressure collection unit 52 in each area. In areas with high odor concentration, the opening of the regulating component 521 is increased to ensure sufficient suction intensity in high-concentration odor areas. In areas with low odor concentration, the opening of the regulating component 521 is decreased to reduce wind resistance and reduce the operating energy consumption of the exhaust module 20.

[0038] For example, in the sludge treatment area 300 with high odor concentration, the control module 30 increases the opening of the regulating component 521, thereby increasing the airflow in the secondary negative pressure collection unit 52 within the sludge treatment area 300 and accelerating the airflow speed. This allows the odor to quickly flow to the corresponding zoned sealed collection module 10 within the sludge treatment area 300 for collection, preventing the diffusion of high-concentration odor. For the impact volatilization area 100 with low odor concentration, the control module 30 decreases the opening of the regulating component 521, thereby reducing the airflow in the secondary negative pressure collection unit 52 within the impact volatilization area 100. This reduces air resistance, enabling zoned adjustment as needed and optimizing system operating energy consumption.

[0039] The deodorization and sealing system for a tobacco wastewater treatment plant provided in this embodiment of the invention includes an adjusting component 521 installed in a secondary negative pressure collection unit 52, which is electrically connected to a control module 30. The control module 30 adjusts the opening of the adjusting component 521 according to the odor concentration in each area, thereby controlling the airflow entering the secondary negative pressure collection unit 52 in each area. This achieves precise adjustment of the airflow in each area, ensuring sufficient extraction in areas with high odor concentrations, achieving stable and efficient sealed collection of odors, and ensuring reasonable energy consumption in areas with low odor concentrations, thus extending the service life of the extraction module 20 and the piping system.

[0040] Optional, you can continue to refer to Figure 1 The control module 30 is also used to control the exhaust module 20 to exhaust air after a delay after the corresponding processing equipment stops, based on the status of the processing equipment, so as to seal the odor in the corresponding collection unit of each area.

[0041] Specifically, the control module 30 is also used to control the exhaust module 20 to exhaust for a delay after the corresponding processing equipment stops, based on the status of the processing equipment. When the monitoring module 40 detects that the processing equipment is in a stopped state, it transmits the processing equipment stopped state signal to the control module 30. The control module 30 then controls the exhaust module 20 to continue exhausting for a preset time to eliminate residual odorous exhaust gases in the processing equipment after it stops operating. Furthermore, different delay times are set for different types of processing equipment in different areas, based on the different areas and the type of processing equipment.

[0042] For example, when the sludge screw press in the sludge treatment area 300 stops operating, the control module 30 controls the exhaust module 20 to continuously exhaust for 10-15 minutes to remove the odor continuously emitted from the residual sludge inside the sludge screw press. When the sludge conditioning tank stops operating, the control module 30 controls the exhaust module 20 to continuously exhaust for 20-30 minutes until the temperature of the sludge conditioning tank drops and the odor emission slows down. When the bar screen stops operating, the control module 30 controls the exhaust module 20 to continuously exhaust for 5 minutes to remove the odor emitted from the dirt remaining on the bar screen teeth.

[0043] The deodorization and sealing system for a tobacco wastewater treatment plant provided in this embodiment of the invention controls the exhaust module 20 to exhaust air after a delay following the shutdown of the corresponding treatment equipment, based on the status of the treatment equipment. This seals the odor within the corresponding collection unit in each area. This design effectively absorbs and collects residual odor inside the equipment, preventing its leakage and improving the sealing performance of the deodorization and sealing system. It solves the environmental pollution problem caused by residual odor failing to dissipate promptly after the treatment equipment stops, leading to its escape from gaps in the equipment.

[0044] Figure 3 This is a schematic diagram of the structure of another deodorization and sealing system for a tobacco wastewater treatment plant provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the monitoring module 40 includes a gas concentration monitoring unit 41 and an equipment status monitoring unit 42. The gas concentration monitoring unit 41 is used to monitor the odor concentration in the corresponding area. The monitoring module 40 includes an equipment status monitoring unit 41, which includes an equipment start / stop status monitoring component 421 and an equipment door opening / closing status monitoring component 422. The equipment start / stop status monitoring component 421 is used to monitor the start / stop status signal of the processing equipment in the corresponding area. The control module 30 is electrically connected to the equipment start / stop status monitoring component 421 and is used to receive the start / stop status signal and control the exhaust module 20 to exhaust air after the corresponding processing equipment stops, based on the start / stop status signal. The equipment door opening / closing status detection component 422 is used to detect the opening / closing status signal of the processing equipment door in the corresponding area. The control module 30 is electrically connected to the equipment door opening / closing status detection component 422 and is used to receive the opening / closing status signal and control the airflow of the exhaust module 20 based on the opening / closing status signal.

[0045] In this embodiment, the monitoring module 40 includes a gas concentration monitoring unit 41 and an equipment status monitoring unit 42. The gas concentration monitoring unit 41 can be understood as a component used to collect odor concentration data in various areas of the tobacco wastewater treatment station in real time. For example, the gas concentration monitoring unit 41 includes, but is not limited to, a gas sensor; this embodiment of the invention does not impose any limitations on this. The equipment status monitoring unit 42 can be understood as a detection component used to detect the operating status of the treatment equipment and output a status signal. The equipment status monitoring unit 42 includes an equipment start-stop status monitoring component 421 and an equipment door opening / closing status monitoring component 422. The equipment start-stop status monitoring component 421 can be understood as a monitoring component that monitors the start-stop status of the wastewater treatment equipment and outputs a status signal. For example, the equipment start-stop status monitoring component 421 includes, but is not limited to, a proximity switch, a limit switch, a current detection module, and a voltage detection module; this embodiment of the invention does not impose any limitations on this. The equipment door opening and closing status monitoring component 422 can be understood as a detection component used to detect the opening or closing status of maintenance doors, sealing doors, and other doors of wastewater treatment equipment in real time, generate door status signals, and transmit them to the control module 30. The equipment door opening and closing status monitoring component 422 includes, but is not limited to, door magnetic sensors.

[0046] Specifically, gas concentration monitoring units 41 are deployed at key locations in different areas to form a monitoring network and monitor the odor concentration in the corresponding areas. For example, H2S sensors and NH3 sensors are installed in the bar screen and sludge dewatering room in the sludge treatment area 300 to monitor the concentration of odor gases containing H2S and NH3 in the sludge treatment area 300.

[0047] Specifically, a device start / stop status monitoring component 421 is installed on each processing device in different areas to monitor the start / stop status signals of the processing devices in the corresponding areas. The control module 30 is electrically connected to the device start / stop status monitoring component 421, receives the start / stop status signals of the processing devices, and controls the exhaust module 20 to exhaust air after a delay after the corresponding processing device stops, based on the start / stop status signals.

[0048] For example, an equipment start-stop status monitoring component 421 is installed on the sludge screw press in the sludge treatment area 300. When the equipment start-stop status monitoring component 421 detects that the sludge screw press has stopped running, the control module 30 receives the sludge screw press stop running signal and controls the ventilation module 20 to continuously ventilate for 10-15 minutes to remove the odor from the sludge remaining in the sludge screw press.

[0049] Specifically, door opening / closing status detection components 422 are installed on the doors of each processing device in different areas to detect the opening / closing status signal of the processing device door in the corresponding area. The control module 30 is electrically connected to the door opening / closing status detection components 422, receives the opening / closing status signal, and controls the airflow of the exhaust module 20 according to the opening / closing status signal.

[0050] For example, a door opening / closing status detection component 422 is installed on the door of the bar screen in the sludge treatment area 300. When the door of the bar screen is opened, the door opening / closing status detection component 422 detects that the door is open. The control module 30 receives the door opening status signal and controls the exhaust module 20 to adjust the exhaust module 20 corresponding to the sludge treatment area 300 to the maximum airflow within 2-3 minutes, ensuring that odors in the bar screen do not escape while the door is open. When the door of the bar screen is closed, the control module 30 controls the exhaust module 20 to automatically return to the normal exhaust mode.

[0051] The deodorization and sealing system for a tobacco wastewater treatment station provided in this embodiment of the invention includes a gas concentration monitoring unit 41 and an equipment status monitoring unit 42 in the monitoring module 40. The gas concentration monitoring unit 41 monitors the odor concentration in the corresponding area, enabling real-time monitoring of the odor concentration in each area. This provides data support for precise adjustment of airflow in different zones, improves odor collection efficiency, and reduces the operating energy consumption of the exhaust module 20. The equipment status monitoring unit 42 includes an equipment start / stop status monitoring component 421 and an equipment door opening / closing status monitoring component 422. The equipment start / stop status monitoring component 421 monitors the start / stop status signals of the treatment equipment in the corresponding area, and the equipment door opening / closing status detection component 422 detects the opening / closing status signals of the treatment equipment doors in the corresponding area. The control module 30 is electrically connected to the equipment start / stop status monitoring component 421 and the equipment door opening / closing status detection component 422, respectively. It receives start / stop status signals and controls the exhaust module 20 to perform delayed exhaust after the corresponding processing equipment stops, thus absorbing and collecting residual odors inside the equipment and preventing odor overflow after the processing equipment stops. The control module 30 also receives opening / closing status signals and controls the airflow of the exhaust module 20 accordingly. When the processing equipment door is open, the exhaust airflow is automatically increased to prevent odors from escaping from the door and reduce the risk of odor overflow from personnel entering and exiting. The exhaust module 20 adaptively adjusts the exhaust airflow based on the start / stop status of the processing equipment, the opening / closing status of the processing equipment door, and different odor concentrations, improving the efficiency and intelligence of the system's sealing and deodorizing process. This solves the problems of inaccurate control during odor collection and low efficiency in sealing and collecting odors.

[0052] Optional, you can continue to refer to Figure 1The deodorization and sealing system of the tobacco wastewater treatment station also includes multiple wastewater treatment devices (not shown in the figure) respectively installed in the impact volatilization zone 100, the biological metabolism zone 200 and the sludge treatment zone 300. The wastewater treatment devices include sealing structures (not shown in the figure); the sealing level of the sealing structure is positively correlated with the odor concentration released by the wastewater treatment devices.

[0053] In this embodiment, the wastewater treatment equipment in different areas includes different sealing structures. A sealing structure can be understood as a sealing component installed at the housing, door, inspection port, or pipe interface of the wastewater treatment equipment to prevent odor leakage. Exemplary examples include, but are not limited to, elastic sealing strips or sealing panels; this embodiment of the invention does not impose limitations on these.

[0054] Specifically, the sealing level of the sealing structure is positively correlated with the odor concentration released by the wastewater treatment equipment. If the odor concentration released by the wastewater treatment equipment is high, the sealing level of its sealing structure should be high and the sealing tightness should be good. If the odor concentration released by the wastewater treatment equipment is low, a sealing structure with a lower sealing level should be configured accordingly to optimize the cost of the sealing structure and the convenience of equipment use.

[0055] For example, for the concrete tanks such as the anaerobic and aerobic tanks in the biological metabolism zone 200, a modular sealing cover system composed of an aluminum alloy frame and corrosion-resistant composite panels is used to ensure the airtightness of the anaerobic and aerobic tanks. For equipment interfaces such as bar screens or sludge dewatering machines, movable modules with quick-opening and closing capabilities and self-sealing functions are used, enabling rapid maintenance without compromising the sealing of the treatment equipment.

[0056] The deodorization and sealing system for tobacco wastewater treatment plants provided in this invention employs different sealing structures for various wastewater treatment devices within the plant. The sealing level of the structure is positively correlated with the odor concentration released by the wastewater treatment device. This ensures that devices releasing high odor concentrations use a high-level sealing structure for a tight seal, preventing odor leakage and suppressing odor escape at its source. For devices releasing low odor concentrations, a suitable sealing structure is used. This simplifies the structure, reduces costs, and facilitates the switching and maintenance of the equipment while maintaining sealing effectiveness. This system solves the problems of traditional deodorization and sealing systems that use the same sealing level for all devices, leading to insufficient sealing and leakage in high-concentration odor devices, and the problems of excessive sealing in low-concentration odor devices, resulting in high costs, complex structures, and inconvenient maintenance.

[0057] Based on the same inventive concept, this invention also provides a method for deodorizing and sealing a tobacco wastewater treatment plant. Figure 4This is a flowchart of a deodorization and sealing control method for a tobacco wastewater treatment plant provided in an embodiment of the present invention. This deodorization and sealing control method for a tobacco wastewater treatment plant can be applied to the deodorization and sealing system of a tobacco wastewater treatment plant provided in any of the above optional embodiments. Figure 4 As shown, a deodorization and sealing control method for a tobacco wastewater treatment plant includes: S101, Receive odor concentration and status of treatment equipment.

[0058] Specifically, based on the process flow and odor release characteristics of the tobacco wastewater treatment plant, the plant is divided into an impact volatilization zone, a biological metabolism zone, and a sludge treatment zone. Multiple monitoring modules are installed in each of these zones to monitor the odor concentration and the status of the corresponding treatment equipment in real time. A control module is electrically connected to both the monitoring and ventilation modules, receiving data on the odor concentration and equipment status from the monitoring modules.

[0059] S102. Adjust the air volume of the exhaust module according to the odor concentration and the status of the treatment equipment, wherein the exhaust volume of each area is positively correlated with the odor concentration of that area.

[0060] Specifically, after receiving the odor concentration and treatment equipment status from the monitoring module in each area, the control module adjusts the exhaust module according to the odor concentration and treatment equipment status, controlling the airflow of the exhaust module. The exhaust volume of each area is positively correlated with the odor concentration in that area. When the monitoring module detects that the odor concentration in its area is greater than a preset range, the control module increases the airflow of the exhaust module to strengthen the air volume in that area. When the monitoring module detects that the odor concentration in its area is less than the preset range, the control module reduces the airflow of the exhaust module to save energy and avoid ineffective air supply.

[0061] The deodorization and sealing control method for tobacco wastewater treatment plants provided in this invention receives odor concentration and treatment equipment status via a control module. Then, it adjusts the airflow of the exhaust module based on these data, with the exhaust flow rate of each area positively correlated with the odor concentration in that area. By precisely controlling the exhaust flow rate of the exhaust module according to the odor concentration and treatment equipment status monitored by the monitoring module in different areas, differentiated and precise air delivery is achieved for each area, effectively curbing odor diffusion. This improves the odor sealing and collection effect while reducing system energy consumption, solving the problems of insufficient odor collection intensity in high-concentration odor areas leading to odor diffusion and excessive exhaust flow in low-concentration odor areas resulting in significant energy waste.

[0062] Optionally, the deodorization and sealing system of the tobacco wastewater treatment plant also includes a negative pressure collection module, which comprises a primary negative pressure collection unit, a secondary negative pressure collection unit, and a tertiary negative pressure collection unit. The secondary negative pressure collection unit includes an adjustment component. The deodorization and sealing control method of the tobacco wastewater treatment plant also includes adjusting the opening degree of the adjustment component according to the odor concentration in each area to control the air volume entering the secondary negative pressure collection unit in each area.

[0063] Specifically, the negative pressure collection module can be understood as a pipeline structure that collects and transports odorous gases generated in each sealed area under negative pressure. It works in conjunction with the exhaust module to create a negative pressure environment, enabling the directional transport of odorous gases to the collection units in each area. The negative pressure collection module includes primary, secondary, and tertiary negative pressure collection units, with multiple units located in the impact evaporation zone, biological metabolism zone, and sludge treatment zone, respectively. These units can be understood as three types of pipelines capable of handling different levels of negative pressure. For example, a primary negative pressure collection unit may include, but is not limited to, a main pipe; a secondary negative pressure collection unit may include, but is not limited to, a branch pipe; and a tertiary negative pressure collection unit may include, but is not limited to, a capillary tube. The regulating component can be understood as an actuator that works with the control module to regulate the airflow in the negative pressure collection module. This regulating component includes, but is not limited to, regulating valves.

[0064] The regulating component is electrically connected to the control module. The control module outputs regulation commands based on the odor concentration in each area. The regulating component, in turn, precisely controls the airflow of the secondary negative pressure collection unit in each area according to the regulation commands output by the control module. In areas with high odor concentration, the opening of the regulating component is increased to ensure sufficient suction intensity in these areas. In areas with low odor concentration, the opening of the regulating component is decreased to reduce air resistance and decrease the energy consumption of the exhaust module.

[0065] The deodorization and sealing control method for tobacco wastewater treatment plants provided in this invention connects an adjustment component to a control module. The control module adjusts the opening of the adjustment component according to the odor concentration in each area, thereby controlling the airflow entering the secondary negative pressure collection unit in each area. This achieves precise adjustment of negative pressure and airflow in each area, ensuring sufficient extraction in high-concentration areas, achieving stable and efficient sealed collection of odors, and ensuring reasonable energy consumption in low-concentration areas, thus extending the service life of the exhaust module and piping system.

[0066] Optionally, the deodorization and sealing control method for tobacco wastewater treatment plants also includes: controlling the exhaust module to exhaust air for a delay after the corresponding treatment equipment stops, based on the status of the treatment equipment, to seal the odor within the corresponding collection unit in each area.

[0067] Specifically, the control module also controls the exhaust module to perform a delayed exhaust after the corresponding processing equipment stops, based on the status of the processing equipment. When the monitoring module detects that the equipment is in a stopped state, it transmits the equipment stop status signal to the control module, which then controls the exhaust module to continue exhausting for a preset time to eliminate any odorous exhaust gases remaining in the processing equipment after it stops operating. Furthermore, different delay times are set for different types of processing equipment in different areas.

[0068] The deodorization and sealing control method for tobacco wastewater treatment plants provided in this invention controls the exhaust module to exhaust air for a delayed period after the corresponding treatment equipment stops, based on the status of the treatment equipment, thus sealing the odor within the corresponding collection unit in each area. By employing this technical solution, residual odor inside the equipment is extracted and collected, preventing its leakage and improving the sealing performance of the deodorization and sealing system. This solves the environmental pollution problem caused by residual odor failing to dissipate promptly after the treatment equipment stops, leading to its escape from gaps in the equipment.

[0069] Figure 5 This is a flowchart of another deodorization and sealing control method for a tobacco wastewater treatment plant provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the method specifically includes: S201, Receive the start / stop status signal of the processing equipment and the opening / closing status signal of the processing equipment door.

[0070] Specifically, the monitoring module includes an equipment status monitoring unit, which comprises an equipment start / stop status monitoring component and an equipment door opening / closing status monitoring component. Equipment start / stop status monitoring components are installed on each processing device in different areas to monitor the start / stop status signals of the processing devices in their respective areas. The control module is electrically connected to the equipment start / stop status monitoring components to receive these signals. Equipment door opening / closing status detection components are installed on the doors of each processing device in different areas to detect the opening / closing status signals of the doors in their respective areas. The control module is electrically connected to these components to receive and adjust the opening / closing status signals accordingly.

[0071] S202. Based on the start / stop status signal, control the exhaust module to exhaust air after a delay following the shutdown of the corresponding processing equipment.

[0072] Specifically, after receiving the start / stop status signal of the processing equipment, the control module controls the exhaust module to exhaust air for a delay after the corresponding processing equipment stops, based on the received start / stop status signal. When the control module receives that the processing equipment is in a stopped state, it does not control the exhaust module in the area where the processing equipment is located to immediately stop the exhaust mode, but continues to control the exhaust module to run continuously for a preset time to collect the residual odor in the processing equipment and prevent the residual odor from dissipating.

[0073] S203. Control the air volume of the exhaust module according to the opening and closing status signal.

[0074] Specifically, after receiving the opening / closing status signal of the processing equipment door, the control module controls the airflow of the exhaust module accordingly. When the control module receives a signal indicating that the processing equipment door is open, it increases the airflow of the exhaust module to ensure that odors inside the processing equipment do not escape while the door is open. When the control module receives a signal indicating that the processing equipment door is closed, it automatically controls the exhaust module to return to normal ventilation mode.

[0075] The deodorization and sealing control method for tobacco wastewater treatment plants provided in this invention receives start / stop status signals and door opening / closing status signals from the treatment equipment. Based on the start / stop status signals, the system controls the exhaust module to delay exhaust after the corresponding treatment equipment stops, and controls the exhaust volume based on the opening / closing status signals. By acquiring the start / stop status of the treatment equipment in real time, delayed exhaust after shutdown is achieved, absorbing and collecting residual odors within the equipment and preventing odor overflow after shutdown. By detecting the door opening / closing status in real time, the system automatically increases the exhaust volume when the door is open, preventing odor escape and reducing the risk of odor spillage from personnel entering and exiting. The system adaptively adjusts the exhaust volume according to the start / stop status of the treatment equipment, the door opening / closing status, and different odor concentrations, improving the efficiency and intelligence of the system's sealing and deodorization. This solves the problems of inaccurate odor collection process and low odor sealing and collection efficiency.
