Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption box technology, and in particular to activated carbon adsorption box for industrial waste gas treatment. Background Technology

[0002] Activated carbon gas adsorption boxes are highly efficient waste gas treatment devices, mainly used to remove organic solvents and pollutants from low-concentration, high-volume waste gases. Activated carbon gas adsorption boxes utilize the unbalanced and unsaturated molecular attraction or chemical bond forces on the surface of activated carbon. When waste gas enters the adsorption box under negative pressure provided by a fan, it comes into contact with the activated carbon surface. Gas molecules are attracted and concentrated on the activated carbon surface, while pollutants in the waste gas are adsorbed onto the activated carbon surface and separated from the gas mixture, thus achieving purification.

[0003] The existing activated carbon adsorption boxes are cumbersome to replace, and after replacement, sealing problems are prone to occur, resulting in poor filtration effect. Utility Model Content

[0004] The purpose of this invention is to provide an activated carbon adsorption box for industrial waste gas treatment, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An activated carbon adsorption box for industrial waste gas treatment includes a rectangular box body integrally injection molded from polypropylene material. A circular air inlet is provided at the center of the top of the box body, and a circular air outlet is provided at the center of the bottom of the box body. A connecting flange is integrally formed around the air inlet, and multiple threaded mounting holes are evenly distributed on the connecting flange. The air inlet is sealed and connected to an external waste gas conveying pipe through the connecting flange.

[0007] The adsorption module includes a longitudinally arranged adsorption mounting frame and an activated carbon bag installed on the adsorption mounting frame. The side wall of the box is formed with a side disassembly port for the adsorption mounting frame to slide laterally. A sliding support frame for the adsorption mounting frame to slide laterally is installed inside the box. A sealing frame is fitted inside the side disassembly port. A sealing seat is provided at the outer end of the adsorption mounting frame to seal against the sealing frame.

[0008] Furthermore, the opening of the sealing frame gradually decreases from the outside to the inside, and silicone sheets are arranged on the side walls of the sealing frame.

[0009] Furthermore, the cross-sectional area of ​​the sealing seat gradually decreases from the outside to the inside.

[0010] Furthermore: the sliding support frame includes a support column installed longitudinally inside the box, and multiple horizontally installed sliding guide plates are arranged at intervals on the support column, with both ends of the sliding guide plates extending toward the side disassembly port respectively.

[0011] Furthermore: the sliding guide plate is provided with a raised transverse guide rail along its length, and the back of the adsorption mounting bracket is formed with a transverse sliding groove along its length that slides in cooperation with the transverse guide rail.

[0012] Furthermore: the guide plate includes a first arc plate and a second arc plate, which are symmetrically arranged to form a "human" structure. The guide plate is arranged between two adjacent adsorption modules, with the lower end of the first arc plate and the second arc plate closer to the adsorption module.

[0013] Furthermore: the first arc-shaped plate and the second arc-shaped plate each include a plate body and a bent plate hinged to the bottom of the plate body.

[0014] Furthermore: the bottom of the plate body is formed with a hinge groove, the hinge groove is fitted with a hinge shaft, the bent plate is formed with a hinge hole connected to the hinge shaft, the hinge hole of the bent plate is rotatably connected to the hinge shaft, and the bent plate can swing around the hinge shaft with damping.

[0015] Furthermore, a filter structure is provided at the air inlet, which includes a gold wire filter and a semi-circular clamp for installing the gold wire filter. The semi-circular clamp is fixed at the air inlet.

[0016] The beneficial effects of this utility model are as follows: The external exhaust gas conveying pipeline is sealed to the air inlet on the top of the box through a connecting flange, so that the exhaust gas can enter the box accurately and in a sealed manner, preventing exhaust gas leakage; after the exhaust gas enters the box, it will pass through multiple adsorption modules and then through activated carbon bags installed on the adsorption mounting rack. The activated carbon bags filter impurity particles, which are adsorbed on the activated carbon bags to achieve purification; when the activated carbon bags have been used for a certain period of time, the adsorption mounting rack can be moved laterally along the sliding support frame according to the disassembly port, and the adsorption mounting rack can be removed from the side disassembly port, thereby replacing the activated carbon bags installed on the adsorption mounting rack.

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1-4 As shown, the activated carbon adsorption box for industrial waste gas treatment includes a rectangular box body 1 integrally injection molded from polypropylene material. A circular air inlet 11 is provided at the center of the top of the box body 1, and a circular air outlet 15 is provided at the center of the bottom of the box body 1. A connecting flange 12 is integrally formed around the air inlet 11. Multiple threaded mounting holes are evenly distributed on the connecting flange 12. An external waste gas conveying pipe 13 is sealed to the air inlet 11 at the top of the box body 1 through the connecting flange 12. The external waste gas conveying pipe 13 is sealed to the air inlet 11 at the top of the box body 1 through the connecting flange 12, so that the waste gas can accurately and sealedly enter the box body 1 and prevent waste gas leakage.

[0035] The adsorption module 3 includes a longitudinally arranged adsorption mounting frame 35 and activated carbon packs 37 mounted on the adsorption mounting frame 35. The side wall of the housing 1 is formed with a side disassembly port 4 for the adsorption mounting frame 35 to slide laterally. A sliding support frame 31 for the adsorption mounting frame 35 to slide laterally is installed inside the housing 1. After the exhaust gas enters the interior of the housing 1, it will pass through multiple adsorption modules 3 and the activated carbon packs 37 mounted on the adsorption mounting frame 35. The activated carbon packs 37 filter impurity particles according to their properties, and these impurities will be adsorbed on the activated carbon packs 37 to achieve purification. When the activated carbon packs 37 have been used for a certain period of time, the adsorption mounting frame 35 can be moved laterally along the sliding support frame 31 through the side disassembly port 4, and the adsorption mounting frame 35 can be removed from the side disassembly port 4 to replace the activated carbon packs 37 mounted on the adsorption mounting frame 35.

[0036] A sealing frame 41 is fitted inside the side disassembly port 4. The opening of the sealing frame 41 gradually decreases in size from the outside to the inside, and a silicone sheet 42 is arranged on the side wall of the sealing frame 41. A sealing seat 43 is provided at the outer end of the adsorption mounting bracket 35, which is in sealing contact with the sealing frame 41. The cross-sectional area of ​​the sealing seat 43 gradually decreases from the outside to the inside. After the adsorption mounting bracket 35 of the adsorption module 3 is inserted inward through the side disassembly port 4, the sealing seat 43 will fit against the opening of the sealing frame 41, and the outer side wall of the sealing seat 43 will fit against the silicone sheet 42 on the side wall of the sealing frame 41, so that the side disassembly port 4 remains sealed, and the exhaust gas inside the box 1 will not leak from the side disassembly port 4.

[0037] Furthermore, the sliding support frame 31 includes a support column 32 longitudinally installed inside the housing 1. Multiple transversely installed sliding guide plates 33 are spaced apart on the support column 32, with both ends of the sliding guide plates 33 extending towards the side disassembly port 4. The sliding guide plates 33 have raised transverse guide rails 34 along their length. The back of the adsorption mounting frame 35 is formed with a transverse sliding groove 36 that slides with the transverse guide rails 34. The adsorption mounting frame 35 slides with the transverse guide rails 34 of the sliding guide plate 33 via the formed transverse sliding groove 36, facilitating the installation of the adsorption module 3. The adsorption mounting frame 35 can move smoothly laterally, allowing it to be removed and replaced from the side disassembly port 4.

[0038] The housing 1 is equipped with an adsorption module 3 and a guide plate 2 that cooperates with the adsorption module 3. The guide plate 2 includes a first arc plate 21 and a second arc plate 22. The first arc plate 21 and the second arc plate 22 are symmetrically arranged to form a "human" structure. The guide plate 2 is arranged between two adjacent adsorption modules 3. The lower end of the first arc plate 21 and the second arc plate 22 is close to the adsorption module 3. After passing through the inlet 11, the exhaust gas flows downwards. Guided by the first arc plate 21 and the second arc plate 22, the exhaust gas can approach the adsorption modules 3 on both sides. Some of the exhaust gas can pass through the activated carbon pack 37 of the adsorption module 3. The activated carbon pack 37 filters impurity particles, and these impurities are adsorbed on the activated carbon pack 37 to achieve purification. Subsequently, the exhaust gas continues to pass through the remaining adsorption modules 3. Under the guidance of multiple guide plates 2, the exhaust gas will pass through more than one adsorption module 3, achieving multiple filtration and adsorption, further improving the purification effect of the exhaust gas. Then, all the purified exhaust gas will enter the outlet 15. A fan is installed at the outlet 15 so that the exhaust gas entering the box 1 can quickly pass through the adsorption modules 3 and flow in a guided manner within the box 1, improving the purification efficiency.

[0039] The first arc-shaped plate 21 and the second arc-shaped plate 22 each include a plate body 23 and a bent plate 24 hinged to the bottom of the plate body 23. The bottom of the plate body 23 has a hinge groove, on which a hinge shaft 25 is installed. The bent plate 24 has a hinge hole 26 connected to the hinge shaft 25. The hinge hole 26 of the bent plate 24 is rotatably connected to the hinge shaft 25, allowing the bent plate 24 to swing with damping around the hinge shaft 25. The curvature of the bent plate 24 can be adjusted by the damped rotational engagement of the hinge shaft 25 and the hinge hole 26, making the gap between the bent plate 24 and the adsorption module 3 adjustable. A portion of the exhaust gas can pass through this gap into the lower guide plate 2, where it is guided. The exhaust gas can then continue to pass through different adsorption modules 3 for purification.

[0040] A filter structure is provided at the air inlet 11, including a gold wire filter 14 and a semi-annular clamp 16 for installing the gold wire filter 14. The semi-annular clamp 16 is fixed at the air inlet 11. The semi-annular clamp 16 is made of stainless steel plate and has an adjusting bolt. The adjusting bolt is rotatably connected to a hole in the housing 1 near the air inlet 11, which can be flexibly adjusted according to the size of the air inlet 11 to ensure that the gold wire filter 14 is firmly installed and facilitates quick replacement when the gold wire filter 14 becomes clogged.

[0041] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
