Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, in particular to an activated carbon adsorption device for waste gas treatment. Background Art

[0002] In the production process of polyvinyl chloride, the polymerization batching process requires adding initiator (liquid), dispersant (powder), etc. to the batching kettle when preparing polymerization aids, which will produce organic waste gas with a strong odor. Therefore, a gas collection hood is set at the batching site to extract the waste gas generated by the batching and transport the waste gas to the activated carbon adsorption device for adsorption.

[0003] The Chinese utility model patent "An activated carbon purifier adsorption structure" with publication number CN218166463U discloses the following content: including a box body, an air inlet, an air outlet, a limit bar, cleaning cotton, an adsorption structure, and an activated carbon drawer. The air inlet is set at the front end of the box body, and the air outlet is set at the rear end of the box body. The limit bars are distributed at the front of the upper and lower ends of the box body. The cleaning cotton is fixed to the inside of the box body through the limit bars. The adsorption structure is installed at the rear part of the box body, and the activated carbon drawer is installed on the adsorption structure through the left end of the box body. The adsorption structure includes an air inlet box, an air outlet box, air vents, a guide plate, and a closed cover. This patent disrupts the flow direction of the exhaust gas entering the box body through the guide plate. The complex structure of the air inlet box and the air outlet box cooperates with the closed cover to alleviate the air flow rate, so that the slowly flowing exhaust gas is fully adsorbed and purified by the activated carbon and then discharged from the exhaust hole.

[0004] However, the drainage structure of the above device simply disrupts the flow direction of the exhaust gas in the box. In fact, the number of activated carbon drawers through which the exhaust gas passes is small, and the activated carbon in the activated carbon drawers cannot be fully utilized to adsorb harmful substances in the exhaust gas, resulting in low adsorption efficiency.

[0005] Therefore, there is an urgent need for an activated carbon adsorption device for waste gas treatment to solve the above technical problems. Utility Model Content

The drawer body extends through the opening into the storage compartment, and the baffle is fixed to the front face of the adsorption box body by screws. The bottom face of the drawer body is provided with adsorption holes 15, and the left and right walls of the drawer body are fixedly mounted with stainless steel screens 16. The drawer body is filled with columnar activated carbon. The stainless steel screen and adsorption holes are sized to prevent the columnar activated carbon from falling out while also allowing exhaust gas to enter smoothly.

[0036] The connecting pipes include four horizontal connecting pipes, namely horizontal connecting pipe A17, horizontal connecting pipe B18, horizontal connecting pipe C19, and horizontal connecting pipe D20; and three vertical connecting pipes, namely vertical connecting pipe A21, vertical connecting pipe B22, and vertical connecting pipe C23.

[0037] The rear parts of storage bins A and B are connected through vertical connecting pipe A, the rear parts of storage bins C and D are connected through vertical connecting pipe B, and the rear parts of storage bins E and F are connected through vertical connecting pipe C; the front left side of storage bin B is connected to the front right side of storage bin C through horizontal connecting pipe B, and the front left side of storage bin D is connected to the front right side of storage bin E through horizontal connecting pipe C.

[0038] The horizontal connecting pipe D connects the exhaust end and the front left side of the storage bin F at the tail end, and the rightmost horizontal connecting pipe A connects the intake end and the front right side of the storage bin A at the lower right corner.

[0039] The activated carbon adsorption device further includes a filter assembly; the filter assembly includes a mounting plate 24 and a filter plate 25 fixedly connected to the mounting plate;

[0040] The interior of the adsorption box body is separated into a transition chamber by a vertical partition 26;

[0041] The vertical partition is located on the right side of the storage bin. The upper and lower sides of the transition chamber are respectively provided with an upper partition 27 and a lower partition 28. The upper partition, lower partition, vertical partition, and the side wall of the adsorption box body form a filter chamber 29.

[0042] The side wall of the front end face of the filter chamber is provided with a socket 30 connected to the filter chamber; the height of the socket matches the height of the filter plate, and the height of the socket is the same as the distance between the upper partition and the lower partition; the filter plate extends into the filter chamber from the socket, and the mounting plate is fixedly connected to the side wall of the front end face of the filter chamber by screws.

[0043] The size of the filter plate matches the size of the filter chamber to ensure that all exhaust gases can pass through the filter plate. A through hole 31 is provided on the right wall of the filter chamber, which is connected to the air inlet end.

[0044] Working principle: When this embodiment is in use, after the activated carbon drawers are filled with columnar activated carbon, they are fixedly and sealedly installed in the adsorption box body. Similarly, the filter plate assembly is also fixedly and sealedly installed in the adsorption box body. The exhaust gas enters the filter chamber from the air inlet end, and after being filtered by the filter plate in the filter chamber, it passes through the horizontal connecting pipe A, storage bin A, vertical connecting pipe A, storage bin B, horizontal connecting pipe B, storage bin C, vertical connecting pipe B, storage bin D, horizontal connecting pipe C, storage bin E, vertical connecting pipe C, storage bin F, horizontal connecting pipe D; and then enters the exhaust end. When the exhaust gas passes through storage bin A, storage bin C, and storage bin E, it enters from the head and is discharged from the tail; when the exhaust gas passes through storage bin B, storage bin D, and storage bin F, it enters from the tail and is discharged from the head.

[0045] The device of this embodiment allows waste gas to enter all storage bins in sequence and be adsorbed by the columnar activated carbon filled in the storage bins. The waste gas treatment path is long, allowing for sufficient adsorption. Furthermore, the columnar activated carbon can be replaced based on the actual adsorption situation. For example, if the columnar activated carbon in the storage bin at the front of the adsorption path adsorbs more waste, the columnar activated carbon at the rear of the adsorption path can be moved to the front, and the rear of the columnar activated carbon can be replaced with a new columnar activated carbon. This can further improve the efficiency of the columnar activated carbon while reducing its cost.

[0046] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Any technical deformation made according to the technical solution of the present invention falls within the protection scope of the present invention.
