Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device for lithium battery recycling. Background Art

[0002] Lithium battery recycling is a systematic project that handles retired or scrapped lithium-ion batteries, such as those for power and consumer electronics. It begins with collection, classification, testing, and evaluation. Then, through pre-processing steps like discharge and disassembly, valuable metals like lithium, cobalt, and nickel are extracted using wet, pyro, and dry methods. This not only achieves resource recycling, but also effectively mitigates the risks of heavy metal and electrolyte contamination, eliminates battery safety hazards, and promotes sustainable resource utilization and green development in the new energy industry.

[0003] When treating waste gas generated by recycled lithium batteries, a multi-technology coupling process has become the mainstream choice. Waste gas treatment begins with dry filtration, which efficiently intercepts large impurities such as metal dust. Next, organic solvents in the electrolyte are separated through condensation recovery technology, achieving secondary resource utilization. Catalytic combustion technology is then used to decompose and purify organic waste gases (VOCs). Alkaline solution spraying is then used to neutralize acidic gases such as hydrogen fluoride (HF) and hydrogen chloride (HCl). Finally, deep adsorption treatment ensures that all waste gas pollutant indicators meet emission standards, establishing an efficient and environmentally friendly full-chain waste gas treatment system.

[0004] At present, activated carbon adsorption boxes are usually used in deep adsorption treatment. The activated carbon particles loaded therein have the advantages of easy availability of raw materials, simple production process, and lower procurement cost under the same adsorption capacity compared with honeycomb activated carbon. However, in actual use, the bottom activated carbon particles that first come into contact with the exhaust gas will be saturated first, causing the micropores and mesopores to be filled with pollutants, thereby affecting the adsorption effect of the upper activated carbon on the exhaust gas. In addition, the saturated activated carbon particles in the bottom layer are easily broken by the squeezing of the upper layer, and the dust generated by the crushing falls into the interior of the adsorption box, which may cause pollution and corrosion of the box. Therefore, the present invention provides a waste gas treatment device for lithium battery recycling and treatment to meet the needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a waste gas treatment device for lithium battery recycling and processing. By setting a mixing component, it can not only push the waste gas to the adsorption cabinet, making it convenient for activated carbon particles to adsorb the waste gas, but also cooperate with the subsequent stirring of the activated carbon particles to promote the waste gas to diffuse outward from the inside of the activated carbon particles, so that the activated carbon particles are in full contact with the waste gas, thereby improving the adsorption efficiency. It can also collect the activated carbon particles that are broken after saturation to prevent them from entering the interior of the activated carbon adsorption box, avoiding internal pollution of the activated carbon adsorption box due to cleaning difficulties. In addition, it can also support the replacement of saturated activated carbon particles without stopping the machine, significantly improving the waste gas treatment efficiency, avoiding affecting the adsorption effect of the upper activated carbon on the waste gas and the problem of saturated activated carbon particles polluting and corroding the box after being broken.

[0044] It should be noted that references in the specification to "one embodiment," "an embodiment," "exemplary embodiments," "some embodiments," etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not necessarily every embodiment will include such specific features, structures, or characteristics. Furthermore, when specific features, structures, or characteristics are described in conjunction with an embodiment, it is within the knowledge of persons skilled in the relevant art to implement such features, structures, or characteristics in conjunction with other embodiments (whether or not explicitly described).

[0045] like Figures 1 to 16 As shown, an embodiment of the present invention provides a waste gas treatment device for lithium battery recycling and processing, including an activated carbon adsorption box 1, wherein the two ends of the activated carbon adsorption box 1 are fixedly connected with an air inlet pipe 101 and an air outlet pipe 102, and a plurality of adsorption cabinets 3 are respectively installed on the inner walls on both sides of the activated carbon adsorption box 1 close to the air outlet pipe 102. The adsorption cabinet 3 is a hollow metal cuboid, and an opening is provided on the top and the side away from the central axis of the activated carbon adsorption box 1. The plurality of adsorption cabinets 3 are divided into two layers, and a first air baffle 104 is fixedly connected between the upper and lower adsorption cabinets 3. The first air baffle 104 is a "Z"-shaped metal plate. The bottom of the lower adsorption cabinet 3 and the top of the upper adsorption cabinet 3 are respectively fixedly connected with a second air baffle 105 and a third air baffle 103. The second air baffle 105 and the third air baffle 103 are both square metal Plates, wherein the first air-isolating plate 104, the second air-isolating plate 105 and the third air-isolating plate 103 are all used to separate the exhaust gas from the adsorbed gas, and a number of cabinet doors 106 are respectively installed on the outer walls on both sides of the activated carbon adsorption box 1 close to the exhaust pipe 102. The cabinet doors 106 are square metal plates with handles, which are installed on the outer wall of the activated carbon adsorption box 1 through hinges, and the positions of the cabinet doors 106 correspond one-to-one to the positions of the adsorption cabinets 3. The cabinet doors 106 are disclosed in the prior art and will not be described in detail; a mixing component, a mixing component is used to enhance the adsorption effect of activated carbon particles on exhaust gas, and the mixing component is connected to the activated carbon adsorption box 1, wherein the interior of the activated carbon adsorption box 1 is also provided with existing structures such as a temperature detection device and a control center. Since the above structure is not affected by the present invention and has weak connectivity with the present invention, it will not be described in detail.

[0046] By setting up a mixing component, the present application can not only push the exhaust gas to the adsorption cabinet 3, making it easier for the activated carbon particles to adsorb the exhaust gas, but also cooperate with the subsequent stirring of the activated carbon particles to promote the exhaust gas to diffuse outward from the inside of the activated carbon particles, so that the activated carbon particles are in full contact with the exhaust gas, thereby improving the adsorption efficiency. It can also collect the activated carbon particles that are broken after saturation to prevent them from entering the interior of the activated carbon adsorption box 1, avoiding internal contamination of the activated carbon adsorption box 1 due to cleaning difficulties. In addition, the design supports the replacement of saturated activated carbon particles without stopping the machine, which significantly improves the exhaust gas treatment efficiency.

[0047] In this embodiment, if Figures 5 to 9As shown, the mixing component includes an adsorption drawer 5, which is a hollow metal cuboid with no seal on the top. The adsorption drawer 5 is used to load activated carbon particles. The adsorption drawer 5 is installed inside the adsorption cabinet 3. A first rotating groove 501 is provided on the inner wall of the bottom of the adsorption drawer 5. The first rotating groove 501 is a circular groove body. A first avoidance groove 502 is provided on the outer wall of the adsorption drawer 5 away from the central axis of the activated carbon adsorption box 1. The first avoidance groove 502 is a semicircular groove body with an overall outline in the shape of a "U". The adsorption drawer 5 is provided with a groove on the outer wall close to the first avoidance groove 502. A pull ring 503 is provided. The pull ring 503 is a metal cylinder and its overall outline is "U"-shaped, which is adapted to the inner wall outline of the first avoidance groove 502. The pull ring 503 can be rotated to fit onto the inner wall of the first avoidance groove 502 to avoid the closing of the cabinet door 106. When the activated carbon particles gradually tend to be saturated, their weight will increase. At this time, the activated carbon particles in the adsorption drawer 5 need to be replaced. The staff can take out the adsorption drawer 5 by pulling the pull ring 503. This not only provides convenience for the staff, but also allows the pull ring 503 to be folded up to avoid affecting the closing of the cabinet door 106.

[0048] In this embodiment, if Figures 2 to 8As shown, the mixing assembly includes a support plate 2, which is a rectangular metal plate. The two ends of the support plate 2 are respectively fixedly connected to the bottom inner wall and the top inner wall of the activated carbon adsorption box 1 near the air inlet pipe 101. The outer walls of the support plate 2 near the two ends are symmetrically fixedly connected with telescopic rods 201. The telescopic rods 201 are disclosed in the prior art and are not described in detail. The outer wall of the support plate 2 near the middle is fixedly connected with a support column 202. The support column 202 is a metal cylinder. The ends of the two telescopic rods 201 away from the support plate 2 are fixedly connected with the same propulsion plate 203. The propulsion plate 203 is a square metal plate, and the outer wall contour of the propulsion plate 203 is adapted to the inner wall contour of the activated carbon adsorption box 1, so the two telescopic rods 201 can push the propulsion plate 20 3 slides along the inner wall of the activated carbon adsorption box 1 to push the exhaust gas toward the adsorption cabinet 3. A first air inlet hole 204 is opened on the outer wall of the propulsion plate 203 near the middle. The first air inlet hole 204 is a circular groove. The exhaust gas will pass through the first air inlet hole 204. Four connecting columns 205 distributed in a circular array are fixedly connected to the outer wall of the propulsion plate 203 on the side away from the air inlet pipe 101. The connecting columns 205 are metal cylinders. The end of the connecting column 205 away from the propulsion plate 203 is fixedly connected to a fixed circular plate 206. The fixed circular plate 206 is a metal circular plate. A pull rod 207 is fixedly connected to the outer wall of the fixed circular plate 206 on the side away from the connecting column 205. The pull rod 207 is a square metal cylinder. The pull rod 207 is away from the activated carbon adsorption box A plurality of pulling teeth 208 distributed in a linear array are fixedly connected to the outer wall of one side of the central axis. The pulling teeth 208 are metal triangular prisms. A first spring 209 is sleeved on the outer wall of the connecting column 205. When the first spring 209 is subjected to force, it will deform along the direction of its bending. The first spring 209 is disclosed in the prior art and will not be described in detail. One end of the first spring 209 is fixedly connected to the outer wall of the fixed circular plate 206 close to the propulsion plate 203. The end of the first spring 209 away from the fixed circular plate 206 is fixedly connected to the cover plate 210. The overall outline of the cover plate 210 is a square metal plate, and four hollow metal circular plates are fixedly connected to the four corners of the square metal plate. The circular groove of the hollow metal circular plate has an inner wall contour that is aligned with the outer wall of the connecting column 205. The profiles are adapted to each other, so the cover plate 210 can slide along the outer wall of the connecting column 205. When the telescopic rod 201 pulls the propulsion plate 203 to slide along the inner wall of the activated carbon adsorption box 1 toward the air inlet pipe 101, the end of the support column 202 away from the support plate 2 will press against the cover plate 210, causing the cover plate 210 to slide along the outer wall of the connecting column 205 in the direction away from the propulsion plate 203. At this time, the first spring 209 is stressed and deformed along its bending direction, allowing the exhaust gas to enter the box through the first air inlet hole 204. When the telescopic rod 201 pushes the propulsion plate 203 to slide along the inner wall of the box away from the air inlet pipe 101, the propulsion plate 203 will push the exhaust gas that has entered toward the adsorption cabinet 3. At this time, the first spring 209 is no longer stressed and recovers its deformation along the bending direction.The cover plate 210 is pushed to slide along the outer wall of the connecting column 205 toward the propulsion plate 203. Finally, the cover plate 210 is tightly attached to the outer wall of the propulsion plate 203 near the first air inlet 204, sealing the first air inlet 204. This mechanism prevents exhaust gas from escaping from the first air inlet 204 during the propulsion process.

[0049] Second sliding grooves 303 are symmetrically provided on the inner walls near the bottom of the adsorption cabinet 3 on both sides. The second sliding grooves 303 are square grooves with arcs at both ends, and the inner wall contour of the second sliding grooves 303 is adapted to the outer wall contour of the pull rod 207, so the pull rod 207 can pass through the second sliding grooves 303. A second rotating groove 304 is provided on the bottom inner wall of the adsorption cabinet 3. The second rotating groove 304 is a circular groove. A rotating column 6 is rotatably connected to the inner wall of the second rotating groove 304. The rotating column 6 is a metal cylinder, and the outer wall contour of the rotating column 6 is adapted to the inner wall contour of the second rotating groove 304, so the rotating column 6 can rotate on the inner wall of the second rotating groove 304. One end of the rotating column 6 is fixedly connected to a rotating circular plate 601, which is a metal circular plate. A first ventilation groove is provided on the bottom outer wall of the rotating circular plate 601 603. The first ventilation groove 603 is a cylindrical groove body. A rotating gear 602 is fixedly connected to the outer wall of the rotating column 6 near the middle. The rotating gear 602 is disclosed in the prior art, so it is not described in detail. The cooperation between the rotating gear 602 and the rotating circular plate 601 can limit the rotating column 6. Since the rotating gear 602 is engaged with the pulling tooth 208 on the pulling rod 207, when the pulling rod 207 slides with the pushing plate 203, it will drive the rotating gear 602 to rotate, and the rotating column 6 will rotate with the rotating gear 602. The above structural setting can push the exhaust gas to the adsorption cabinet 3 through the push of the pushing plate 203, so as to facilitate the subsequent adsorption of the activated carbon particles in the adsorption drawer 5 to adsorb the exhaust gas. The rotating gear 602 can also be driven to rotate by the pulling rod 207 to provide power for the subsequent stirring of the activated carbon particles.

[0050] In this embodiment, if Figures 5 to 8 and Figure 14As shown, the adsorption cabinet 3 has a first sliding groove 301 symmetrically provided on the inner wall near the middle on both sides. The first sliding groove 301 is a square groove body. The inner walls at both ends of the first sliding groove 301 are fixedly connected to the two ends of the sliding column 302. The sliding column 302 is a metal cylinder. The outer wall of the sliding column 302 is sleeved with a second spring 507. When the second spring 507 is subjected to force, it will deform along the direction of its bending. The second spring 507 is disclosed in the prior art, so it is not described in detail. One end of the second spring 507 is fixedly connected to the inner wall of one end of the first sliding groove 301 near the central axis of the activated carbon adsorption box 1, and the other end of the second spring 507 is fixedly connected to the sliding plate 504. The sliding plate 5 The overall outline of 04 is rectangular and made of metal. It consists of three parts: a rectangular metal plate in the middle and a square metal plate at both ends. The outer wall contours of the two ends of the sliding plate 504 are respectively adapted to the inner wall contours of the two first sliding grooves 301, so the sliding plate 504 can slide along the inner wall of the first sliding groove 301. Sliding holes 506 are opened on the outer walls of the sliding plate 504 near both ends. The sliding holes 506 are circular grooves, and the inner wall contours of the sliding holes 506 are adapted to the outer wall contours of the sliding column 302. Therefore, the sliding plate 504 can slide along the outer wall of the sliding column 302 in the first sliding groove 301. The outer walls of the sliding plate 504 near both ends are symmetrically fixed with The guide plate 505 is a metal plate with an arc at one end. The distance between the two guide plates 505 is adapted to the width of the adsorption drawer 5, which can guide the adsorption drawer 5 when it is pushed into the adsorption cabinet 3. When the staff pushes the adsorption drawer 5 with the new activated carbon granules into the adsorption cabinet 3, the adsorption drawer 5 will contact the outer wall of the sliding plate 504 under the guiding effect of the curved end of the two guide plates 505, and push the sliding plate 504 to slide along the outer wall of the sliding column 302 toward the direction of the central axis of the activated carbon adsorption box 1. At this time, the second spring 507 will be deformed in the direction of its bending under the force. When the adsorption drawer 5 is ready to be drawn into the adsorption cabinet 3, the adsorption drawer 5 will be pushed into the adsorption cabinet 3. When the drawer 5 is taken out of the adsorption cabinet 3, the second spring 507 will no longer be subjected to force and will restore its deformation along its bending direction, pushing the sliding plate 504 to slide along the outer wall of the sliding column 302 in the direction away from the central axis of the activated carbon adsorption box 1. At this time, the sliding plate 504 will push the adsorption drawer 5 to slide in the direction away from the central axis of the activated carbon adsorption box 1. With the above structural arrangement, when the adsorption drawer 5 is pushed into the adsorption cabinet 3, the two guide plates 505 can provide a guiding effect for the adsorption drawer 5. The elastic restoring force of the second spring 507 can also be used to push the adsorption drawer 5 to slide outward through the sliding plate 504, making it easier for the staff to take the adsorption drawer 5 out of the adsorption cabinet 3.

A third spring 606 is sleeved on the outer wall near the middle of the rotating column 6. When the third spring 606 is subjected to force, it will deform along the direction of its bending. The third spring 606 is disclosed in the prior art and will not be described in detail. One end of the third spring 606 is fixedly connected to the top outer wall of the rotating gear 602, and the other end of the third spring 606 is fixedly connected to the pressing circular plate 607 The pressing circular plate 607 is a hollow metal circular plate. The pressing circular plate 607 is located in the middle of the groove body, and its inner wall contour is adapted to the outer wall contour of the rotating column 6, so the pressing circular plate 607 can slide on the outer wall of the rotating column 6, and four pressing columns 608 distributed in a circular array are fixedly connected to the top outer wall of the pressing circular plate 607. The pressing columns 608 are metal rectangular blocks, and the outer wall contour of the pressing columns 608 is adapted to the inner wall contour of the third ventilation groove 605, so the pressing columns 608 can slide on the inner wall of the third ventilation groove 605, so that the exhaust gas can be prevented from passing through the third ventilation groove 605. The outer wall of the adsorption cabinet 3 away from the central axis of the activated carbon adsorption box 1 is fixedly connected with a blocking plate 305, and the blocking plate 305 is composed of two square metal plates and metal cylinders. The screw threaded post 402 is a metal plate with a screw thread on the inner wall, and the screw threaded post 402 is a metal plate with a screw thread on the inner wall. A third rotating groove is provided on the outer wall of one side. The third rotating groove is a "convex" shaped circular groove body, and the inner wall contour of the third rotating groove is adapted to the outer wall contour of the end of the threaded column 4 away from the rotating handle 401, so the threaded column 4 can rotate on the inner wall of the third rotating groove. Four first pressing blocks 403 are symmetrically fixedly connected to the outer walls of both sides of the U-shaped column 402. The first pressing blocks 403 are trapezoidal metal blocks. The four first pressing blocks 403 have an inclined outer wall on one side abutting against the second pressing blocks 509. The second pressing block 509 is a trapezoidal metal block. The second pressing block 509 has an inclined outer wall on one side abutting against the inclined outer wall on the first pressing block 403. The top outer walls of the four second pressing blocks 509 are all fixedly connected with the same partition 508.The partition 508 is a square metal plate, and the outer wall contour of the partition 508 is adapted to the inner wall contour of the adsorption cabinet 3, so the partition 508 can slide on the inner wall of the adsorption cabinet 3, and an avoidance hole is opened on the outer wall near the middle of the partition 508, and the avoidance hole is a circular groove, and the inner wall contour of the avoidance hole is adapted to the contour composed of the four first limit columns 604 and the rotating column 6, so the partition 508 can slide on the inner wall of the adsorption cabinet 3 along the outer wall of the rotating column 6. When the staff pushes the adsorption drawer 5 with new activated carbon particles into the adsorption cabinet 3, the adsorption drawer 5 will, under the guiding action of the curved end of the two guide plates 505, contact the outer wall of the sliding plate 504 and push the sliding plate 504 along the sliding column 302 The outer wall of the activated carbon adsorption box 1 slides toward the center axis of the activated carbon adsorption box 1. At this time, the staff needs to rotate the rotating handle 401 counterclockwise, which will drive the threaded column 4 to rotate and displace along the inner wall of the threaded hole 306 in the direction away from the center axis of the adsorption cabinet 3, and drive the U-shaped column 402 to slide toward the direction of the threaded hole 306. In this way, the outer wall of the inclined side of the first pressing block 403 no longer abuts against the outer wall of the inclined side of the second pressing block 509. Under the action of gravity of the adsorption drawer 5, the adsorption drawer 5 will be pressed on the top outer wall of the partition 508, causing the partition 508 to slide along the inner wall of the adsorption cabinet 3 toward the bottom of the adsorption cabinet 3, which will drive the pressing circular plate 607 to displace toward the bottom of the adsorption cabinet 3. The third spring 606 will be stressed and deformed in the direction of its bending, and the pressing column 608 will slide along the inner wall of the third ventilation groove 605 toward the bottom of the adsorption cabinet 3 under the drive of the pressing circular plate 607, so that the pressing column 608 will not prevent the exhaust gas from passing through the third ventilation groove 605. When the activated carbon particles are saturated and need to be replaced, the staff needs to rotate the rotating handle 401 clockwise, which will drive the threaded column 4 to rotate and displace along the inner wall of the threaded hole 306 toward the direction of the central axis of the adsorption cabinet 3, and push the U-shaped column 402 to slide in the direction away from the threaded hole 306. Since the outer wall of one side of the first pressing block 403 is in contact with the outer wall of one side of the second pressing block 509, as the U When the shaped column 402 slides in the direction away from the threaded hole 306, it will drive the partition 508 to slide along the inner wall of the adsorption cabinet 3 toward the top of the adsorption cabinet 3, and the partition 508 will lift the adsorption drawer 5. At this time, the first plug-in slot 610 will slide out from the outer wall of the end of the rotating column 6 away from the rotating circular plate 601 during the rotation of the rotating column 6, so that the rotating platform 609 no longer rotates. At the same time, the third spring 606 is no longer stressed and recovers its deformation along the direction of its bending, and pushes the pressing circular plate 607 to move toward the top of the adsorption cabinet 3. The pressing circular plate 607 will contact the bottom outer wall of the partition 508, preventing the exhaust gas entering from the first sliding slot 301 from entering the adsorption cabinet 3 through the avoidance hole on the partition 508.The pressure column 608 follows the pressure circular plate 607 and slides along the inner wall of the third ventilation groove 605 toward the top of the adsorption cabinet 3, preventing exhaust gas from passing through the third ventilation groove 605. With this structural arrangement, the handle 401 can be rotated to push the partition 508 to lift the adsorption drawer 5, preparing for subsequent removal operations. At the same time, the pressure column 608, driven by the elasticity of the third spring 606, can close the third ventilation groove 605, blocking the flow of exhaust gas, allowing the replacement of saturated activated carbon particles without stopping the machine, significantly improving exhaust gas treatment efficiency.

[0052] In this embodiment, if Figure 6 、 Figure 7 and Figures 10 to 16As shown, the rotating column 6 is connected to the rotating table 609 at one end away from the rotating circular plate 601.

A first plug-in groove 610 is provided on the outer wall of the bottom of the rotating table 609. The first plug-in groove 610 is a square groove body with an overall cross-shaped contour. The outer wall contour of the rotating column 6 is adapted to the inner wall contour of the first plug-in groove 610 at one end away from the rotating circular plate 601. Therefore, the end of the rotating column 6 away from the rotating circular plate 601 is plugged into the first plug-in groove 6 10, a ventilation column 611 is fixedly connected to the top outer wall of the rotating table 609, and the ventilation column 611 is a metal cylinder. The ventilation column 611 is symmetrically fixedly connected to the second limiting column 612 on the outer wall close to the rotating table 609, and the second limiting column 612 is a metal cuboid. A second ventilation groove 614 is opened inside the ventilation column 611, and the second ventilation groove 614 is a cylindrical groove body, and the second ventilation groove 614 is connected to the first plug-in groove 610. A second air inlet 613 is symmetrically opened on the outer wall of the ventilation column 611 away from the rotating table 609, and the second air inlet 613 is a circular groove body, and the second air inlet 613 is connected to the second ventilation groove 614. A stirring column 7 is inserted on the outer wall of the ventilation column 611, and the stirring column 7 is a metal column with an arc on the top. It is a rectangular parallelepiped, and the length of the stirring column 7 is adapted to the width of the adsorption drawer 5, so the stirring column 7 can rotate inside the adsorption drawer 5, and a second plug-in slot 701 is provided on the bottom outer wall of the stirring column 7. The second plug-in slot 701 is composed of three parts: a square slot body at both ends and a circular slot body in the middle, and the inner wall contour of the second plug-in slot 701 is adapted to the contour formed by the ventilation column 611 and the two second limiting columns 612, so the ventilation column 611 can be plugged into the second plug-in slot 701, and a third sliding slot 704 is provided on the outer wall of one end of the stirring column 7. The third sliding slot 704 is a square slot body with a curved top, and a second avoidance slot 702 is provided on the bottom inner wall of the third sliding slot 704. The second avoidance slot 702 is a square shaped trough body, the second avoidance groove 702 can avoid the exhaust gas flowing out from the second air inlet 613, so that the exhaust gas can enter the stirring column 7. A number of third air inlet holes 703 are provided on the top outer wall of the stirring column 7. The third air inlet hole 703 is a circular trough body. The third air inlet hole 703 can allow the exhaust gas in the stirring column 7 to enter the adsorption drawer 5 through the third air inlet hole 703. A storage box 705 is slidably connected to the inner wall of the stirring column 7. The storage box 705 is composed of three parts: a square metal plate with an arc at the top at both ends and a hollow metal cuboid in the middle. The storage box 705 is used to collect the broken activated carbon particles falling from the third air inlet 703. Third avoidance grooves 707 are symmetrically provided on the outer walls of both sides of the storage box 705 near the top.The third avoidance groove 707 is a square groove body with arcs at both ends. The exhaust gas entering the stirring column 7 passes through the third avoidance groove 707 and is then discharged from the third air inlet 703. The outer walls of the top of the storage box 705 near both sides are symmetrically fixed with inclined plates 708. The inclined plates 708 are inclined metal plates. The inclined plates 708 can guide the broken activated carbon particles falling into the third air inlet 703 into the storage box 705. A pulling groove 706 is provided on the outer wall of one end of the storage box 705. The pulling groove 706 is an "L"-shaped groove body, which is convenient for the staff to pull the storage box 705 out of the stirring column 7. When the staff puts the stirring column 7 on the outer wall of the ventilation column 611, the stirring column 7 will be driven to rotate with the rotation of the rotating table 609, which can stir the activated carbon particles in the adsorption drawer 5, so that the activated carbon particles can be fully mixed with the exhaust gas, and the exhaust gas entering the stirring column 7 is discharged from The waste gas passes through the third avoidance groove 707 and is then discharged into the adsorption drawer 5 loaded with activated carbon particles through the third air inlet 703, where it diffuses outward from the inside of the activated carbon particles, facilitating the adsorption of exhaust gas by the activated carbon particles. When the activated carbon particles in the adsorption drawer 5 are almost saturated, the activated carbon particles will become easily broken. In this way, during the rotation of the stirring column, some of the broken activated carbon particles will fall into the storage box 705 from the third air inlet 703 and will not fall into the inside of the activated carbon adsorption box 1. The above structural setting can not only promote the diffusion of exhaust gas from the inside of the activated carbon particles to the outside through the rotation of the stirring column 7, so that the activated carbon particles are in full contact with the exhaust gas, thereby improving the adsorption efficiency; it can also collect the activated carbon particles that fall into the third air inlet 703 into the storage box 705, preventing them from entering the inside of the activated carbon adsorption box 1. This is convenient for staff to clean and can prevent the activated carbon particles that adsorb exhaust gas from contaminating the equipment in the box.

[0053] The working principle of the technical solution provided by the present invention is as follows:

[0054] When in use, the two telescopic rods 201 can push the propulsion plate 203 to slide along the inner wall of the activated carbon adsorption box 1. When the telescopic rod 201 pulls the propulsion plate 203 to slide along the inner wall of the activated carbon adsorption box 1 toward the air inlet pipe 101, the end of the support column 202 away from the support plate 2 will press against the cover plate 210, causing the cover plate 210 to slide along the outer wall of the connecting column 205 away from the propulsion plate 203. At this time, the first spring 209 is stressed and deformed along its bending direction, allowing the exhaust gas to enter the adsorption box through the first air inlet hole 204. When the telescopic rod 201 pushes the propulsion plate 203 to slide along the inner wall of the box away from the air inlet pipe 101, the propulsion plate 203 will push the exhaust gas that has entered toward the adsorption cabinet 3. At this time, the first spring 209 It is no longer under stress and recovers its deformation in the bending direction, pushing the cover plate 210 to slide along the outer wall of the connecting column 205 toward the propulsion plate 203. Finally, the cover plate 210 is close to the outer wall of the propulsion plate 203 near the first air inlet 204, closing the first air inlet 204. This mechanism can prevent exhaust gas from overflowing from the first air inlet 204 during the propulsion process. When the pull rod 207 slides following the propulsion plate 203, it will drive the rotating gear 602 to rotate, and the rotating gear 602 will drive the rotating column 6 to rotate, and the rotating table 609 inserted in the end of the rotating column 6 away from the rotating disk will rotate with the rotating column 6, and the ventilation column 611 and the two second limiting columns 612 will rotate with the rotating table 609 and drive the stirring column 7 to rotate.

[0055] The staff pushes the adsorption drawer 5 with the new activated carbon particles into the adsorption cabinet 3. The adsorption drawer 5 will contact the outer wall of the sliding plate 504 under the guidance of the curved end of the two guide plates 505, and push the sliding plate 504 to slide along the outer wall of the sliding column 302 toward the central axis of the activated carbon adsorption box 1. The second spring 507 will be squeezed by the sliding plate 504 and deformed in the direction of its bending. At this time, the staff needs to turn the rotating handle 40 counterclockwise. 1, which will drive the threaded column 4 to rotate and displace along the inner wall of the threaded hole 306 in the direction away from the central axis of the adsorption cabinet 3, and drive the U-shaped column 402 to slide in the direction of the threaded hole 306, so that the outer wall of the inclined side of the first pressing block 403 no longer abuts against the outer wall of the inclined side of the second pressing block 509, and under the action of the gravity of the adsorption drawer 5, the adsorption drawer 5 will be pressed on the top outer wall of the partition 508, so that the partition 508 moves along the inner wall of the adsorption cabinet 3 toward the bottom of the adsorption cabinet 3. 605, and the first plug-in slot 610 on the rotating platform 609 will be sleeved during the rotation of the rotating column 609. It is connected to the outer wall of the end of the rotating column 6 away from the rotating circular plate 601, so that the rotating column 6 will drive the rotating table 609 to rotate, and the exhaust gas will pass through the first ventilation groove 603, the third ventilation groove 605, the first plug-in groove 610, the second ventilation groove 614 in sequence, and then enter the second plug-in groove 701 through the second air inlet 613, and flow to both sides of the stirring column under the avoidance of the second avoidance groove 702, and finally pass through the third avoidance groove 707 and enter the activated carbon particles from the third air inlet 703.

[0056] When the activated carbon granules are saturated and need to be replaced, the staff needs to rotate the rotating handle 401 clockwise, which will drive the threaded column 4 to rotate and displace along the inner wall of the threaded hole 306 toward the central axis of the adsorption cabinet 3, and push the U-shaped column 402 to slide in the direction away from the threaded hole 306. Since the inclined outer wall of one side of the first pressing block 403 abuts against the inclined outer wall of one side of the second pressing block 509, as the U-shaped column 402 slides in the direction away from the threaded hole 306, it will drive the partition 508 to slide along the inner wall of the adsorption cabinet 3 toward the top of the adsorption cabinet 3, and the partition 508 will lift the adsorption drawer 5. At this time, the first plug-in slot 610 will slide out from the outer wall of the end of the rotating column 6 away from the rotating circular plate 601 during the rotation of the rotating column 6, so that the rotating platform 609 no longer rotates. At the same time, the third spring 606 is no longer under force and recovers along its curved direction. The pressing plate 607 will be deformed and push the pressing circular plate 607 to move toward the top of the adsorption cabinet 3. The pressing circular plate 607 will contact the bottom outer wall of the partition 508 to prevent the exhaust gas entering from the first sliding groove 301 from entering the adsorption cabinet 3 through the avoidance hole on the partition 508. The pressing column 608 will follow the pressing circular plate 607 to slide along the inner wall of the third ventilation groove 605 toward the top of the adsorption cabinet 3, preventing the exhaust gas from passing through the third ventilation groove 605. In this way, the cabinet door 106 can be opened and the pulling ring can be pulled to remove the adsorption drawer 5. At this time, the second spring 507 will no longer be subjected to force and will restore its deformation along the direction of its bending, pushing the sliding plate 504 to slide along the outer wall of the sliding column 302 in the direction away from the central axis of the activated carbon adsorption box 1. At this time, the sliding plate 504 will push the adsorption drawer 5 to slide in the direction away from the central axis of the activated carbon adsorption box 1, providing convenience for the staff to take out the adsorption drawer 5.

[0057] After taking out the adsorption drawer 5, the saturated activated carbon particles therein can be poured out; then remove the stirring column, pull out the storage box 705 by pulling the groove 706, pour out the broken activated carbon particles and dispose of them harmlessly. After cleaning, slide the storage box 705 back into the stirring column, and then connect the stirring column to the outer wall of the ventilation column 611, and finally load new activated carbon particles into the adsorption drawer 5.
