[0031] As described in the background section, the equipment has low efficiency in desorption during actual use, cannot process large amounts of waste gas in a timely manner, and cannot clean inorganic gases or other impurities in the waste gas, resulting in slow adsorption.

[0032] To solve this technical problem, this utility model provides an adsorption device that is applied to waste gas treatment.

[0033] Specifically, please refer to Figure 1-Figure 3The adsorption device specifically includes: a filter pipe 2, the filter pipe 2 includes a filter box 6, the filter box 6 is provided with an adsorption component inside, and a plug-in filter component 7 is plugged into one side of the filter box 6. The adsorption component is used to adsorb organic matter in the waste gas, and the plug-in filter component 7 is used for the preliminary filtration of the waste gas.

[0034] Desorption box 1 is located on one side of filter pipe 2 and is fixedly connected to filter pipe 2. Desorption box 1 is equipped with desorption components inside. A storage groove is opened at the lower end of the interior of desorption box 1. An anti-backflow net 8 is installed in the storage groove. The anti-backflow net 8 is located below the desorption components and is slidably connected to the storage groove.

[0035] The adsorption device provided by this utility model separates desorption and adsorption through the design of the adsorption component. In this way, adsorption occurs on the other side while desorption is in progress. When both sides are completed, the device is switched. This not only increases work efficiency but also makes the operation simple and convenient.

[0036] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figure 1-Figure 7 An adsorption device includes: a filter pipe 2, the filter pipe 2 including a filter box 6, the filter box 6 having an adsorption component inside, and a plug-in filter component 7 plugged into one side of the filter box 6. The adsorption component is used to adsorb organic matter in the waste gas, and the plug-in filter component 7 is used for preliminary filtration of the waste gas. Specifically, the filter pipe 2 is responsible for the filtration and passage of the waste gas.

[0039] Desorption box 1 is located on one side of filter pipe 2 and is fixedly connected to filter pipe 2. Desorption box 1 contains a desorption assembly. A collection groove is opened at the lower end of the interior of desorption box 1, and an anti-backflow net 8 is installed in the collection groove. The anti-backflow net 8 is located below the desorption assembly and is slidably connected to the collection groove. Specifically, desorption box 1 is responsible for the desorption of activated carbon and the collection of desorbed organic matter. The detachable structure of the anti-backflow net 8 facilitates the cleaning of the collected organic matter. The anti-backflow holes on the anti-backflow net 8 are wider at the top and narrower at the bottom, making it easy for organic matter to enter but difficult to exit.

[0040] Furthermore, the desorption assembly includes a sealed heating door 3 and an exhaust fan 5. The sealed heating door 3 is rotatably connected to the end of the desorption chamber 1 furthest from the filter pipe 2. Multiple heating lamps 4 are fixedly connected to the sealed heating door 3. The exhaust fan 5 is located at the upper end of the desorption chamber 1 and is fixedly connected to the desorption chamber 1. Specifically, when the adsorption moving frame 9 is inside the desorption chamber 1 and needs to be desorbed, the heating lamps 4 heat up the frame for desorption, and the exhaust fan 5 is used to quickly cool down the frame and improve the recovery speed of the adsorption moving frame 9.

[0041] Furthermore, the adsorption assembly includes a drive gear 10, which is fixedly connected to the output end of a motor. The motor is fixedly connected inside the filter pipe 2 and near the desorption chamber 1. Adsorption moving frames 9 are provided on both sides of the drive gear 10. The two adsorption moving frames 9 are located inside the desorption chamber 1 and the filter pipe 2 respectively and are slidably connected to both. Specifically, the rotation of the drive gear 10 can drive the sliding of the adsorption moving frames 9, allowing them to be interchanged between the desorption chamber 1 and the filter pipe 2, thus enabling simultaneous adsorption and desorption.

[0042] Furthermore, the adsorption moving frame 9 includes a filter frame 15, inside which an activated carbon plate 11 is placed. A limiting buckle assembly 14 is rotatably connected to the filter frame 15, which limits the movement of the activated carbon plate 11. A driven rack 13 is fixedly connected to the lower end of the filter frame 15, and the driven rack 13 meshes with a drive gear 10. Heat-insulating sealing strips 12 are fixedly connected to both sides of the filter frame 15. Specifically, when the limiting buckle assembly 14 rotates onto the activated carbon plate 11, it can limit the movement of the activated carbon plate 11. When it is necessary to release the limitation, the limiting buckle assembly 14 can be rotated away from the activated carbon plate 11. This design facilitates the replacement of the activated carbon plate 11.

[0043] Furthermore, the limiting buckle assembly 14 includes a limiting buckle rod 16 and a limiting buckle pin 19. One end of the limiting buckle rod 16 is rotatably connected to the filter frame 15, and the other end of the limiting buckle rod 16 is fixedly connected to a limiting buckle block 17. A groove is provided inside the limiting buckle block 17, and a limiting buckle cap 18 is slidably connected in the groove. A spring is fixedly connected between the limiting buckle cap 18 and the groove. The limiting buckle pin 19 is located below the limiting buckle rod 16 and is fixedly connected to the filter frame 15. In summary, the design of the limiting buckle block 17 allows the limiting buckle assembly 14 to limit activated carbon plates 11 of different thicknesses, and the limiting buckle pin 19 is used to limit the rotation of the limiting buckle rod 16.

[0044] Example 2:

[0045] The adsorption device provided in Example 1 has been further optimized, specifically, as follows: Figure 8-Figure 9As shown, the plug-in filter assembly 7 includes a filter moving frame 20, inside which are arranged multiple filter screens 22. A limit handle assembly 21 is provided on one side of the filter moving frame 20. The limit handle assembly 21 includes a first limit handle 23. A second limit handle 24 is arranged horizontally inside the first limit handle 23. The second limit handle 24 is slidably connected to the first limit handle 23. Two limit rods 25 are rotatably connected to the second limit handle 24. Two movable cavities are opened in the filter moving frame 20 corresponding to the positions of the limit rods 25. Limit caps 26 are slidably connected inside the two movable cavities. Limit springs 27 are fixedly connected between the limit caps 26 and the movable cavities. The ends of the two limit rods 25 away from the second limit handle 24 extend into the movable cavities at the same end. The limit rods 25 are rotatably connected to the limit caps 26 at the same end. A limit port is opened in the filter box 6 corresponding to the position of the movable cavity. The end of the limit caps 26 away from the movable cavity extends out of the filter moving frame 20 and is plugged into the limit port. Specifically, when the second limit handle 24 is pushed towards the first limit handle 23, the limit lever 25 pulls the limit keycap 26 towards the spring, contacting the limit of the insertion filter assembly 7 and the filter box 6. This facilitates the replacement of the filter screen 22, and the wheels under the insertion filter assembly 7 make its movement easier.

[0046] In practical use, the filter pipe 2 is connected to the air inlet by inserting one end of the filter assembly 7. The exhaust gas is initially filtered by the filter assembly 7 to remove dust, debris and inorganic matter, and then enters the adsorption assembly for adsorption of organic matter. When it is necessary to desorb the activated carbon plate 11, the motor is started to rotate the drive gear 10. The drive gear 10 drives the adsorption moving frame 9 to slide into the desorption box 1 for desorption. The adsorption moving frame 9 in the desorption box 1 slides to the filter pipe 2 to continue adsorption. The anti-backflow net 8 is used to collect the desorbed organic matter.
