Description

Technical Field

[0001] This invention relates to the field of temporary storage cabinet technology, specifically a leak-proof hazardous waste temporary storage cabinet. Background Technology

[0002] Currently, hazardous waste temporary storage cabinets are integrated and modular devices designed specifically for the safe and compliant temporary storage of various hazardous wastes. By providing a controlled, enclosed environment, they prevent the leakage and spread of hazardous waste, effectively protecting the safety of the environment and personnel. The single filter plates used in traditional temporary storage cabinets are prone to problems such as complete blockage, difficulty in cleaning up scattered solid debris, backflow of solid material accumulation and low efficiency of waste liquid separation. In addition, hazardous waste tanks are prone to shaking, displacement and tipping, and leakage. Waste liquid spills from the tank wall and flows without a directional flow. The flow guide hole is blocked by pressure, resulting in the failure of the anti-seepage function. When errors occur during routine management, leading to delays in manual inspections or low efficiency in manual pumping, the overflow of waste liquid can cause secondary leakage and pose a high risk of personnel contact with hazardous waste. Furthermore, the leaked waste liquid is merely collected without neutralization, demulsification, or oil-liquid separation, which does not comply with hazardous waste disposal standards. A single treatment liquid cannot be adapted to mixed waste liquids. The waste gas generated during storage is not organized for diffusion, and a single filter material cannot handle multiple components of harmful gases. After prolonged use, the filter material will quickly become saturated and needs to be replaced frequently. In addition, the waste gas purification is incomplete, the tank opening is not sealed properly and leaks continuously. There is no way to seal it in time and clean up the residual liquid, so the leakage range continues to expand. Furthermore, dust and particles accumulate on the gas and solid-liquid separation end, manual disassembly and cleaning are tedious and require long downtime, and fine dust is easily dispersed again. Summary of the Invention

[0003] The purpose of this invention is to provide a leak-proof hazardous waste temporary storage cabinet to solve the problems mentioned in the background art.

It is used to prevent leakage and separate the solid and liquid. The gas separation mechanism is respectively installed on the rear side of the storage frame and the top of the inner cavity, and the gas separation mechanism separates the gas generated in the inner cavity of the storage frame.

[0006] Preferably, a solid-liquid separation filter plate or an arc-shaped separation filter plate is installed at the top of the inner cavity of the collection port. The solid-liquid separation filter plate has a circular arch structure in the middle and a concave cross-section around the bottom of the solid-liquid separation filter plate. The arc-shaped separation filter plate has a concave structure in the middle and a concentric circle structure when viewed from above. The cross-section of the arc-shaped separation filter plate has a stepped structure.

[0007] Preferably, the storage frame has a suction hole at the corresponding position of the collection port at the rear bottom end, the bottom end of the collection port has an inclined structure, a monitoring end is installed at the rear side of the bottom end of the collection port, and the monitoring end is a sensor, and the storage frame has a first parallel structure at the rear bottom end, and the first parallel structure includes a storage mechanism.

[0008] Preferably, the first parallel structure includes a layered mechanism, a fixed long frame is installed in the middle of the rear side of the storage frame, a second parallel structure is provided in the inner cavity of the fixed long frame, and the second parallel structure includes a multi-layer separation mechanism. The top end of the storage mechanism is connected to the bottom end of the fixed long frame, a suction execution mechanism is installed at the top end of the fixed long frame, and the suction execution mechanism is specifically a suction pump. The bottom end of the multi-layer separation mechanism is provided with a third parallel structure, and the third parallel structure includes a separation end processing mechanism.

[0009] Preferably, the third parallel structure includes a depth processing mechanism, a movable plate is installed at the top of the storage frame, and a plurality of compressed push springs are installed at equal intervals around the top of the movable plate, and the top of the push springs is connected to the top of the inner cavity of the storage frame, and the second parallel structure includes a separation processing mechanism.

[0010] Preferably, the inner cavity of the movable plate is provided with an annular groove, and a plurality of jet heads are equidistantly installed around the bottom of the movable plate. The jet heads are made of silicone material. Connection holes are provided around the bottom of the movable plate at the corresponding positions of the jet heads. A connecting air pipe is installed at the top of the suction actuator. The top of the connecting air pipe passes through the rear top of the storage frame and connects to the top of the movable plate. A delivery hole is provided at the top of the movable plate at the corresponding position of the connecting air pipe. The part of the connecting air pipe in the inner cavity of the storage frame is a flexible tube structure.

[0011] Preferably, a compression airbag is installed at the bottom of the movable plate, and the bottom of the compression airbag has a concave structure around its inner cavity, with the hardness being lowest at the concave structure around the bottom of the compression airbag.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a fixed mesh plate to initially intercept large solid particles, followed by fine separation through a lower irregularly shaped separation end, progressively improving the solid-liquid separation accuracy. The irregularly shaped structure, with a central arch and concave sides, directs solid impurities to the concave areas for easy cleaning. The central arch area maintains a constant flow channel, preventing blockage of the entire filter plate and ensuring continuous airflow of waste liquid and within the cabinet. It also avoids situations where a single filter plate cannot adapt to different leakage velocities and solid impurities of varying particle sizes. A liquid level sensor monitors the waste liquid level in real time, automatically activating a suction pump to drain when full, preventing overflow and leakage. An odor sensor monitors the waste gas concentration in real time, providing immediate warnings and initiating waste gas treatment if levels exceed limits. This avoids delays in manual inspections, preventing waste liquid overflow and subsequent secondary leakage, and also prevents VOC and acid / alkali emissions from exceeding limits without warning, leading to uncontrolled diffusion of harmful gases and potential environmental and safety hazards. 2. Upon triggering a leak or excessive exhaust gas, the limiting electromagnetic block loses power and magnetic force, driving the moving plate downwards via a spring. This causes the compression airbag to flexibly press against the tank opening, and the bottom concave area expands to achieve a circumferential seal, quickly stopping continuous leakage and controlling the risk of leakage immediately. Purified circulating gas is then sprayed out through the jet nozzle to blow down the surface of the storage tank, removing attached residual liquid and debris. The entire process is unmanned and close-range, reducing safety risks. The purified gas flows back into the cabinet for repeated circulation until the exhaust gas meets the standards, resulting in more thorough exhaust gas purification and strict control of fugitive emissions.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-2 and Figures 5-6 The present invention provides a technical solution: a leak-proof hazardous waste temporary storage cabinet, including a storage frame 1, a frame cover 2 installed on the front side of the storage frame 1, and including a gas separation mechanism 4 and a solid-liquid separation mechanism 5; The solid-liquid separation mechanism 5 is located at the bottom of the inner cavity of the storage frame 1. The solid-liquid separation mechanism 5 is used to prevent leakage and separate the solid and liquid. The bottom of the inner cavity of the storage frame 1 is provided with a funnel-shaped collection slot 502, the bottom of the inner cavity of the collection slot 502 is provided with a collection port 504, a fixed mesh plate 501 is installed at the top of the inner cavity of the collection slot 502, a number of protrusions are installed at equal intervals at the top of the fixed mesh plate 501, and a storage tank 3 is placed at the top of the fixed mesh plate 501. The top of the inner cavity of the collection port 504 is equipped with a solid-liquid separation filter plate 503 or an arc-shaped separation filter plate 8. The solid-liquid separation filter plate 503 has a rounded arch structure in the middle, and the bottom cross-section of the solid-liquid separation filter plate 503 has a concave structure, and the bottom of the concave part has an arc-shaped structure. The arc-shaped separation filter plate 8 has a concave structure as a whole. The arc-shaped separation filter plate 8 has a concentric circle structure when viewed from above, and the cross-section of the arc-shaped separation filter plate 8 has a stepped structure, and each step has an arc structure. During the use of the solid-liquid separation filter plate 503, through the structure of the central arch and the surrounding concave areas, when the solid-liquid separation filter plate 503 separates, the large-sized solids accumulated in the concave areas around the edges are collected in a concentrated manner. This concentrated collection facilitates centralized processing in the later stages. Furthermore, the central arch structure of the solid-liquid separation filter plate 503 prevents large-sized solids from accumulating at the top of the entire solid-liquid separation filter plate 503 and causing blockage. In addition, when airflow is formed inside the storage frame 1 later, the airflow will not be blocked due to blockage. Moreover, even if leakage continues later, the flowing waste can still be separated and processed through the arched areas where no waste has accumulated. During the use of the arc-shaped separation filter plate 8, when the leaked waste flows to the upper part of the arc-shaped separation filter plate 8, the large solid objects are accumulated and collected step by step from high to low through the arc structure at each step. When the arc structure at the upper level is full, it will flow to the arc structure at the next level. Through gradual separation and collection, it avoids collecting large fixed objects in only one place, which may lead to insufficient time to process them later. This would result in too many large solid objects being collected and overflowing into the collection trough 502, making later cleaning inconvenient. Also, when there is leaked waste flowing again later, the overflow will obstruct the flow efficiency. At the same time, the design of the stepped structure will not affect the normal flow of air in the later stage.

[0017] A suction hole 506 is provided at the bottom rear end of the storage frame 1, corresponding to the collection port 504. The bottom end of the inner cavity of the collection port 504 is inclined. A monitoring end, which is a sensor, is installed on the rear side of the bottom end of the inner cavity of the collection port 504. An odor sensor is installed on the rear side of the inner cavity of the storage frame 1. A control panel is installed on the right side of the storage frame 1, and the odor sensor and the sensor are electrically connected to the control panel. Limiting rings 508 are installed around the bottom end of the inner cavity of the storage frame 1, located around the collection slot 502. An extrusion layer 509 is installed around the inner periphery of the 8, and an expansion cavity 505 is formed around the inner cavity of the extrusion layer 509. Several discharge holes 510 are equidistantly formed around the inner periphery of the limiting ring 508 and the extrusion layer 509, and the discharge holes 510 have an arched structure. The extrusion layer 509 is made of elastic material, and the hardness is lowest at the position corresponding to the expansion cavity 505 in the middle of the extrusion layer 509. A control valve head is installed on the left side of the limiting ring 508, and a conveying channel is formed in the inner cavity of the limiting ring 508 at the corresponding position of the expansion cavity 505. The specific implementation method is as follows: Waste organic solvents, waste mineral oils, waste acids and alkalis, waste dyes and coatings, packaging materials contaminated with organic / acid / alkali hazardous waste, and mixed laboratory waste liquids and residues are placed in storage tank 3. After filling, the tank is placed directly into storage frame 1. The bottom of storage tank 3 contacts the protrusion at the top of fixed mesh plate 501, creating a gap between storage tank 3 and fixed mesh plate 501. In case of abnormalities during storage, such as storage tank 3 breaking or the lid not being closed tightly causing shaking and spillage, the stored waste will flow directly to the bottom of the inner cavity of storage frame 1. The fixed mesh plate 501 installed at the bottom of the inner cavity of storage frame 1 will then collect the waste. Large solids in the material are separated. The initially separated waste flows into the collection tank 502 and then into the collection port 504. When the waste reaches the top of the collection port 504, it comes into contact with the solid-liquid separation filter plate 503. The solid-liquid separation filter plate 503 separates the fixed substances in the waste, allowing the separated material to flow directly into the collection port 504. When too much waste accumulates in the inner cavity of the collection port 504, the sensor is triggered to start the suction pump 408 through the control panel to suck up the waste. The fixed mesh plate 501 and the solid-liquid separation filter plate 503 perform initial separation of the leaking waste. When the storage tank 3 is placed inside the storage frame 1, the bottom of the storage tank 3 is fixed by the limiting ring 508, and the extrusion layer 509 is extruded. The reaction force generated during extrusion improves the stability of the storage tank 3 when it is placed. Since the extrusion layer 509 is relatively hard, it will not extrude the discharge hole 510 even when it is extruded, thus preventing the discharge hole 510 from becoming blocked. When the top of the storage tank 3 is not tightly sealed and spillage occurs, the spilled waste flows down the outside of the storage tank 3 and flows through the discharge holes 510 on all four sides to the fixed mesh plate 501 for initial separation.

[0018] A first parallel structure is provided at the bottom rear side of the storage frame 1. The first parallel structure includes, but is not limited to, the following specific embodiments: Please see Figures 2-3 Method 1: The first parallel structure includes a storage mechanism 507. A storage frame 5072 is installed at the bottom rear side of the storage frame 1. A working one-way valve 5071 is installed at the bottom of the storage frame 5072, and a suction tube is installed at the bottom of the working one-way valve 5071. The bottom end of the suction tube is connected to the corresponding position of the suction hole 506 at the bottom rear side of the storage frame 1. An arc-shaped baffle 5073 is installed at the upper end of the inner cavity of the storage frame 5072, and the bottom of the arc-shaped baffle 5073 is surrounded by openings. There is a storage slot 5074, and the inner cavity of the storage slot 5074 is filled with a mud-like treatment agent. A mesh is installed at the bottom of the inner cavity of the storage slot 5074. A connecting pipe 5075 is installed at the top of the storage frame 5072, and the top of the connecting pipe 5075 is connected to the bottom of the fixed long frame 409. The inner cavity of the storage frame 5072 is filled with treatment liquid. The distance between the bottom of the storage slot 5074 and the top surface of the treatment liquid is very small, and there is a distance between the treatment liquid and the top of the storage frame 5072. The specific implementation method is as follows: When the suction pump 408 is started to generate suction force on the inner cavity of the storage frame 5072, the working one-way valve 5071 and the connecting pipe 5075 are used in conjunction to generate suction force on the inside of the suction hole 506, and the waste accumulated at the bottom of the inner cavity of the collection port 504 is sucked out and directly sucked into the storage frame 5072, so that the waste comes into contact with the processing liquid placed inside the storage frame 5072, thereby performing neutralization treatment. During the suction process, because the gas flows inside the processing liquid, the top of the processing liquid is continuously tumbling due to the airflow. The tumbling processing liquid comes into contact with the processing agent filled inside the storage tank 5074, producing a water-soluble state, so that the processing agent and the processing liquid are fused together, further improving the neutralization efficiency. If the waste contains oily substances, oil-liquid separation treatment is performed through the processing liquid. After the waste liquid enters the storage frame 5072, it comes into contact with the treated liquid and the sludge or solid treatment agent in the storage tank 5074, completing acid-base neutralization, demulsification, oil-water separation, and pollutant stabilization. It is compatible with mainstream hazardous waste liquids such as HW06, HW08, HW34, and HW35. After pretreatment, it is transported in compliance with regulations. The suction airflow drives the treated liquid to tumble dynamically, enhancing the contact area between the agent and the waste liquid, resulting in more thorough mixing and improved treatment efficiency. Through the arc-shaped baffle 5073 and the liquid level difference design, physical separation of gas and liquid is achieved, preventing the waste liquid from flowing back into the gas pipeline, protecting the upstream waste gas separation unit, and avoiding the situation where the leaked waste liquid is collected without harmless pretreatment, which does not comply with hazardous waste disposal regulations, and where the agent and waste liquid are not mixed sufficiently, resulting in low neutralization and oil-liquid separation efficiency.

[0019] Please see Figure 10 Method 2, and the first parallel structure includes a layered mechanism 511. A collection frame 5111 is installed at the bottom of the fixed long frame 409, and the bottom of the collection frame 5111 is connected to the top of the working one-way valve 5071. Several layered frames 5112 are installed equidistantly in the inner cavity of the collection frame 5111, and a connecting ring pipe 5114 is installed in the middle of each layered frame 5112. The connecting ring pipes 5114 at the upper and lower positions are connected to each other. Several conveying air holes 5115 are opened around the connecting ring pipe 5114. An annular inclined plate 5113 is installed around the inner cavity of the layered frame 5112. The upper part of the connecting ring pipe 5114 is provided with several flow ports 5118 at equal intervals around its perimeter. The upper part of the inner cavity of the connecting ring pipe 5114 is provided with an annular connecting plate 5117. The inner cavity of the annular connecting plate 5117 is hollow. A multi-way solenoid valve 5116 is installed in the middle of the annular connecting plate 5117. The multi-way solenoid valve 5116 is electrically connected to the control panel. The output end of the bottom of the conveying air hole 5115 is located at the bottom of the inner cavity of the layered frame 5112. The top of the conveying air hole 5115 is located at the upper part of the inner cavity of the connecting ring pipe 5114. The layered frame 5112 contains processing liquid. The specific implementation method is as follows: When pumping liquid from waste materials, first switch the control of the bottom multi-way solenoid valve 5116, so that the working end of the bottom of the multi-way solenoid valve 5116 is closed, while the working ends around it are open. During pumping, the liquid is drawn into the bottom layered frame 5112 through the conveying air hole 5115, and comes into contact with and neutralizes the liquid inside the layered frame 5112. At this time, the bottom of the upper multi-way solenoid valve 5116 is open, while the working ends around it are closed. Since there are gaps between the layered frames 5112, the liquid pumped into the corresponding layered frame 5112 will not be drawn into the upper layered frame 5112. The airflow will then flow into the annular connecting plate 5117 through the surrounding flow ports 5118. The working end of the bottom layered frame 5112 allows airflow to flow into the upper connecting ring pipe 5114. This, combined with the open multi-way solenoid valve 5116 at the bottom, allows airflow to flow into the fixed long frame 409 via suction. When the bottom layered frame 5112 reaches the time set by the control panel, the control panel switches the control of the bottom multi-way solenoid valve 5116, opening the bottom working end and closing the surrounding working ends. The control panel then switches the control of the upper-level multi-way solenoid valve 5116, causing the upper-level layered frame 5112 to repeat the above movement. This achieves layered processing, allowing different processing liquids to be added to the layered frames 5112 in advance at different locations, and avoiding the reduction in effectiveness over time caused by continuously using a single liquid processing area. The multi-stage layered frames 5112 can be individually filled with different functional agents to specifically treat multi-component mixed waste liquids, greatly expanding their applicability. The flow path is switched sequentially by the multi-port solenoid valve 5116, and multiple layered frames 5112 work in rotation. When a single agent fails, it automatically switches to a backup unit, allowing continuous operation without shutdown and improving work efficiency. The gas and liquid paths are independently divided by the connecting ring pipe 5114 and the conveying air hole 5115, and the two phases do not interfere with each other, avoiding flooding and airflow blockage. The modular layered design allows for independent maintenance of each unit without affecting the normal operation of the overall mechanism. This avoids the decline in the efficacy of single-tank treatment liquids after long-term use, frequent shutdowns for liquid replacement, inability to operate continuously, and the inability of a single treatment liquid to adapt to mixed hazardous waste liquids containing acids, alkalis, oils, and organic matter.

[0020] Please see Figure 2-4 A fixed long frame 409 is installed in the middle of the rear side of the storage frame 1. The top end of the storage mechanism 507 is connected to the bottom end of the fixed long frame 409. A suction actuator is installed at the top end of the fixed long frame 409, and the suction actuator is specifically a suction pump 408. A movable plate 401 is installed at the top of the storage frame 1. Several compressed push springs 404 are installed at equal intervals around the top of the movable plate 401, and the top of the push springs 404 are connected to the top of the inner cavity of the storage frame 1. An annular groove 403 is opened around the inner cavity of the movable plate 401. Several air nozzles 402 are installed at equal intervals around the bottom of the movable plate 401, and the air nozzles 402 are made of silicone material. Connection holes are opened around the bottom of the movable plate 401 at the corresponding positions of the air nozzles 402. A connecting air pipe 407 is installed at the top of the suction actuator. The top of the connecting air pipe 407 passes through the rear top of the storage frame 1 and connects to the top of the movable plate 401. A delivery hole is opened at the top of the movable plate 401 at the corresponding position of the connecting air pipe 407, and the part of the connecting air pipe 407 in the inner cavity of the storage frame 1 is a flexible tube structure. A compression airbag 406 is installed at the bottom of the movable plate 401. The bottom of the inner cavity of the compression airbag 406 has a concave structure around it. The hardness of the concave structure around the bottom of the compression airbag 406 is the lowest. A limiting electromagnetic block 405 is installed at the top of the inner cavity of the storage frame 1. The bottom of the limiting electromagnetic block 405 is magnetically attracted to the magnetic plate installed at the top of the movable plate 401. A stabilizing slide rail is installed at the upper middle part of the rear side of the inner cavity of the storage frame 1. A stabilizing slide rod is slidably installed on the outside of the stabilizing slide rail. The front end of the stabilizing slide rod is connected to the rear side of the movable plate 401. The limiting electromagnetic block 405 is electrically connected to the control panel. When the movable plate 401 moves, it drives the stabilizing slide rod to slide outside the stabilizing slide rail, thereby improving the guidance and stability of the movable plate 401 when it moves. The specific implementation method is as follows: When hazardous waste leaks or seeps into the inner cavity of storage tank 3, it causes an abnormality in the air inside storage frame 1, which is detected by the odor sensor. This triggers the control panel to start the suction pump 408 and the alarm installed inside the control panel to notify the staff. The suction pump 408 creates a suction force in the inner cavity of the fixed long frame 409, and the connecting pipe 5075 creates a suction force in the inner cavity of storage frame 5072. Finally, the suction pipe and suction hole 506 create a suction force at the bottom of the inner cavity of storage frame 1, thus removing the air from inside storage frame 1. The gas is drawn into the fixed long frame 409, where the multi-layer separation mechanism 411 installed inside the fixed long frame 409 adsorbs and separates the hazardous waste particles in the gas. The separated gas is then transported to the connecting gas pipe 407, which in turn transports it to the annular trough 403. Finally, it is sprayed into the storage box 1 through the jet nozzle 402. This process is repeated until the air inside the storage box 1 is deemed qualified. This is detected by the odor sensor, and then the suction pump 408 is turned off to stop working. At this point, the staff can open the storage box 1 for processing. When the control panel is triggered, the power supply to the limit electromagnetic block 405 is disconnected, causing the limit electromagnetic block 405 to lose its magnetism and the moving plate 401 to lose its restraint. The compressed push spring 404 drives the moving plate 401 to move downward, which in turn drives the jet head 402 and the compression airbag 406 to move downward, so that the bottom end of the compression airbag 406 contacts and squeezes the lid at the top of the storage tank 3. Since the gas ejected by the jet head 402 blows from top to bottom, the airflow contacts the outside of the storage tank 3, blowing away the waste material attached to the outside of the storage tank 3. When the compression airbag 406 is squeezed, the concave structure around the bottom end of the compression airbag 406 expands downward. The expanded compression airbag 406 contacts and squeezes the lid, thereby temporarily sealing it and preventing further leakage.

[0021] The inner cavity of the fixed elongated frame 409 is provided with a second parallel structure, which includes, but is not limited to, the following specific embodiments: Please see Figures 2-4 Method 1: The second parallel structure includes a multi-layer separation mechanism 411. Several multi-layer separation mechanisms 411 are equidistantly installed in the inner cavity of the fixed long frame 409. The multi-layer separation mechanism 411 has a ring structure and the inner cavity of the multi-layer separation mechanism 411 has a hollow structure. A magnetic coupling is installed in the middle of each multi-layer separation mechanism 411. A rotating rod 410 is installed between the magnetic couplings. The top of the rotating rod 410 at the top is connected to the output end of the bottom of the suction pump 408. The inner cavities of several multi-layer separation mechanisms 411 at different positions are filled with different separation substances. Several air holes are equidistantly opened at the top and bottom of the multi-layer separation mechanism 411. Different filter substances are filled in the multi-layer separation mechanism 411 at different positions. The motor installed inside the suction pump 408 is a double-head motor. The output end of the bottom of the double-head motor is connected to the rotating rod 410 at the top. The specific implementation method is as follows: When waste leaks, toxic or polluting gases will be generated. Depending on the hazardous waste being stored, different adsorption and separation substances are added to the multi-layer separation mechanism 411 at different locations in advance. When the waste liquid in the waste is drawn into the storage frame 5072, since there is a distance between the processing liquid and the top of the inner cavity of the storage frame 5072, the drawn waste liquid will not come into contact with the connecting pipe 5075. Therefore, the generated waste gas will be drawn into the bottom separation working end for separation and adsorption treatment. After the waste gas passes through the bottom separation working end, it will flow into the top separation working end and then adsorb and separate other substances in the waste gas again. By using different substances at different locations for separation and adsorption treatment, the sufficiency and efficiency of the waste gas in the separation and treatment process are ensured. By using a multi-layered structure filled with dust removal filter media, activated carbon, acid and alkali adsorption filter media, and molecular sieves, it separates solid particles, organic vapors, and acidic / alkaline gaseous components in stages, making it suitable for purifying a wider range of waste gases. The combination of annular hollow structure and all-area air pores ensures a large airflow cross-sectional area, low wind resistance, and smooth airflow. The integrated power of the dual-head motor can be linked to the rear self-cleaning mechanism, resulting in a high degree of structural integration. This avoids the situation where a single filter media cannot simultaneously remove multiple components of waste gas such as dust, VOCs, and acidic / alkaline gases, leading to substandard treatment, filter layer blockage, increased wind resistance, and decreased gas separation efficiency.

[0022] Please see Figure 11 Method 2: The second parallel structure includes a separation processing mechanism 7. The multi-layer separation mechanism 411 has processing slots 701 around its inner cavity, and processing filter plates 702 are installed at the bottom of the processing slots 701. The processing slots 701 have conveying slots at their top. A multi-way control solenoid valve 705 is installed at the top of the multi-layer separation mechanism 411 relative to the conveying slots. The multi-layer separation mechanism 411 has conveying air passages 704 around its middle, and a connecting conveying pipe is installed at the top of the conveying air passages 704. The top of the connecting conveying pipe is connected to one side of the multi-way control solenoid valve 705. A crossbar 703 is installed at the bottom of the multi-layer separation mechanism 411 relative to the processing slots 701. The crossbar 703 has an equidistant protrusion structure around its outer perimeter. An installation slot is opened at the bottom of the processing slots 701 at the corresponding position of the processing filter plates 702. The specific implementation method is as follows: Before storing hazardous waste, according to the general type of hazardous waste, add the corresponding adsorption and separation material into the corresponding treatment tank 701. After storing the corresponding hazardous waste, open the working end of the multi-way control solenoid valve 705 at the bottom of the corresponding position and close the working end of the multi-way control solenoid valve 705 on one side of the conveying air passage 704, so that the airflow cannot flow from the inside of the conveying air passage 704, and ensure that the airflow flows from the inside of the corresponding treatment tank 701 for adsorption, filtration and separation. The airflow passes through the separation working end filled with different adsorption and separation materials from bottom to top, so as to separate the different harmful substances contained in the waste gas. During use, the bottom separation working end can be used first. The working end of the bottom multi-way control solenoid valve 705 is opened, while the side near the conveying air passage 704 is closed. The bottom of the corresponding position of the upper multi-way control solenoid valve 705 is closed, while the side near the conveying air passage 704 is open. After the airflow is adsorbed and separated by the bottom separation working end, the upper conveying air passage 704 is open, and the airflow flows directly through the conveying air passage 704. When the bottom separation working end has been working for too long, the working end of the bottom multi-way control solenoid valve 705 is switched, the bottom working end is closed, and the working end near the conveying air passage 704 is started. The upper-level separation working end is also started to repeat the above workflow, increasing the separation time and avoiding the need for processing and replacement when the critical point of use is reached in a short time. According to the needs of use, different adsorption and separation substances can be filled into the processing empty tank 701 at the corresponding position of each layer, or the same adsorption and separation substance can be filled into the processing empty tank 701 at the separation working end of each layer. When a certain adsorption and separation substance is needed, or when the adsorption and separation substance in a certain processing empty tank 701 has been used for too long, the multi-way control solenoid valve 705 at other positions can be activated to switch the corresponding working end during operation. By switching the gas path using the multi-way control solenoid valve 705, the corresponding filter media unit can be activated as needed. The separation medium is matched according to the type of temporarily stored hazardous waste (organic / acid / alkali / oil-containing), making the waste gas treatment more targeted. The flow path is switched in a time-sharing manner, and the standby unit is switched after the working unit is saturated. The equipment can operate continuously without interruption, extending the overall service life. This avoids the problem of using only a single set of filter media in a fixed flow path, which can lead to rapid saturation of local filter media, short equipment life, and inability to flexibly switch adsorption media according to the type of hazardous waste, resulting in insufficient targeting.

[0023] The bottom end of the multi-layer separation mechanism 411 is provided with a third parallel structure, which includes, but is not limited to, the following specific embodiments: Please see Figures 2-4 Method 1: The third parallel structure includes a separation end processing mechanism 412, which is located at the bottom of the multi-layer separation mechanism 411. Movable brush strips 4122 are installed on the upper sides of the rotating rod 410 through rubber top rods, and working brush heads 4121 are installed on the top of each movable brush strip 4122. The specific implementation method is as follows: After the multi-layer separation mechanism 411 at the corresponding position has been used for a long time, the magnetic coupling at the corresponding position and the upper magnetic coupling at the corresponding position will be activated through the control panel. The rotation of the rotating rod 410 will drive the movable brush strip 4122 at the corresponding position to rotate, and drive the working brush head 4121 to rotate. This will clean the top of the working brush head 4121 with the air inlet at the bottom of the multi-layer separation mechanism 411, ensuring the normal use of the air inlet and avoiding the accumulation of a large amount of fixed particulate matter on the air inlet after prolonged use, which would cause blockage of the air inlet port, prevent the airflow from flowing normally, and affect the efficiency of gas separation. The rotating rod 410 is linked to the rotating brush strip 4122, which automatically and mechanically cleans the air intake end face, clears blockages in real time, and continuously ensures gas flow and separation efficiency. The magnetic coupling independently controls the start and stop, and can clean on a timed or on-demand basis without stopping the whole machine. Automation replaces manual disassembly, reduces maintenance difficulty and safety risks, and avoids dust and solid particles being trapped at the gas separation air intake end face, which can cause airflow obstruction and continuous decline in separation efficiency due to pore blockage.

[0024] Please see Figures 7-9 Method Two: The third parallel structure includes a depth processing mechanism 6. A bristle layer 601 is installed on the outside of the movable brush strip 4122. The bristle layer 601 includes a long bristle layer and a fluffy bristle layer. The movable brush strip 4122 has a hollow inner cavity, and liquid is added inside the hollow structure. The liquid can be a viscous liquid in specific implementations. Several movable oblique openings 604 are equidistantly spaced at the top of the movable brush strip 4122. A moving tube 602 is slidably installed inside each of the movable oblique openings 604. An extrusion ring layer 605 is installed around the inner cavity of each movable oblique opening 604. The extrusion ring layer 605 is made of silicone material. A blocking top plate is installed at the top of the moving tube 602. The top of the blocking top plate is connected to the corresponding brush layer 601. The inner cavity of the moving tube 602 is provided with a conveying channel 606. A sealing sleeve 603 is installed around the bottom of the moving tube 602, and the top of the sealing sleeve 603 is connected to the top of the inner cavity of the movable brush strip 4122. The sealing sleeve 603 is made of rubber. When the moving tube 602 moves, it squeezes the sealing sleeve 603. Later, the squeezed sealing sleeve 603, combined with the gravity under the tilt, allows the moving tube 602 to quickly return to its original position. Several spray nozzles 608 are equidistantly opened around the moving tube 602 at the corresponding positions of the conveying channel 606, and a blocking mesh frame 607 is installed in the inner cavity of the spray nozzle 608. The specific implementation method is as follows: During the rotation and cleaning process of the movable brush bar 4122, centrifugal force is generated, which pushes the moving tube 602 to move away from the rotating rod 410. When the moving tube 602 slides in the inner cavity of the movable inclined port 604, the corresponding spray nozzle 608 moves and separates from the extrusion ring layer 605. Then, the corresponding spray nozzle 608 is unobstructed, and the liquid in the inner cavity of the movable brush bar 4122 is transported to the inside of the spray nozzle 608 through the conveying channel 606. When the liquid flows inside the spray nozzle 608, the blocking mesh frame 607 disperses the liquid and blocks it, preventing the liquid from flowing away completely in a short time due to the centrifugal force. This results in a shorter liquid utilization time. When the dispersed liquid is sprayed to the outside, it comes into contact with the bristle layer 601, wetting the velvet layer in the bristle layer 601. After the bristle layer 601 cleans up the accumulated particulate impurities during operation, the wetted velvet layer adsorbs smaller particulate impurities, preventing the cleaned impurities from drifting to the bottom of the separation end and re-attaching to the air inlet end later, which would affect daily use over time. (The faster the rotation speed, the greater the centrifugal force generated, the more the spray nozzle 608 separates from the extrusion ring layer 605, and the larger the amount of liquid sprayed, thus ensuring that the velvet layer is wetted in a short time.) The centrifugal force generated by the rotation of the movable brush bar 4122 pushes the moving tube 602 out, and the cleaning fluid is atomized and sprayed out through the spray nozzle 608, wetting the brush bristles to achieve wet dust removal. Fine dust is wetted and adsorbed, preventing secondary dust generation. The dust removal effect is far superior to dry sweeping. The spray volume is adaptive to the speed, and the higher the speed (the more dust), the greater the spray volume. The cleaning fluid is supplied on demand, and the utilization rate is high. The liquid flow is dispersed by the blocking mesh frame 607, and the atomization is uniform. The combination of the silicone extrusion ring layer 605 and the hard rubber sealing sleeve 603 ensures that the moving tube 602 slides smoothly. After stopping, it automatically resets and closes the spray nozzle 608, with no leakage faults. The structure has excellent stability and sealing performance.
