[0001] The present invention relates to the technical field of chemical waste gas detection and purification treatment, and particularly to a chemical waste gas detection and purification treatment system. Background Art

[0002] During the chemical production process, a large amount of waste gas containing harmful substances is generated. If directly discharged, it will cause serious harm to the environment and human health. Therefore, the detection and purification treatment of chemical waste gas are crucial. In the prior art, common waste gas treatment systems usually include equipment such as spray towers and activated carbon filters, and pollutants in the waste gas are removed through spray absorption and activated carbon adsorption. However, the traditional activated carbon filtration device has the following deficiencies:

[0003] 1. Most existing activated carbon filter plates are fixedly installed. When replacing, the entire filtration device needs to be shut down and disassembled, which is time-consuming and laborious, and partial replacement cannot be achieved to maintain the adsorption saturation gradient, resulting in waste of resources and a decrease in treatment efficiency.

[0004] 2. The waste gas may leak from the gaps between adjacent filter plates during the filtration process, affecting the purification effect and even resulting in the emission of unqualified waste gas.

[0005] Therefore, there is an urgent need for a chemical waste gas detection and purification treatment system with reasonable structural design, convenient maintenance and replacement, good sealing performance, and the ability to detect the emission status in real time. Summary of the Invention

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] Refer to Figures 1-12 , a chemical waste gas detection and purification treatment system, including a spray tower 1, an activated carbon filter 2 and a tail gas emission device 3. The spray tower 1 includes an air inlet 101 and an exhaust outlet 102. The exhaust outlet 102 is connected to the gas inlet pipe 201 of the activated carbon filter 2 through a pipeline. The exhaust pipe 202 of the activated carbon filter 2 is connected to the tail gas emission device 3 through a pipeline;

[0041] The waste gas first passes through the spray tower 1 for spray absorption and then enters the activated carbon filter 2 for absorption. Finally, it enters the tail gas emission device 3. The top of the tail gas emission device 3 is provided with a tail gas emission pipe 301. A discharge detector 302 is installed near the bottom of the outer side of the tail gas emission pipe 301. After the treated tail gas is detected and qualified by the discharge detector 302, it is discharged at a high altitude through the tail gas emission pipe 301.

[0042] A maintenance opening 203 is provided at the top of the activated carbon filter 2. A first baffle 204 is detachably installed on the maintenance opening 203. A support mechanism 4 is provided inside the activated carbon filter 2. A plurality of support seats 402 are provided at the top of the support mechanism 4. An activated carbon filter plate 5 is installed on the support seat 402. The number of activated carbon filter plates 5 is three or four. After the activated carbon filter plate 5 is used for a period of time, it will become inactivated and needs to be replaced with a new one. At this time, the maintenance opening 203 can be opened to replace the new activated carbon filter plate 5. The activated carbon filter plate 5 is a series of multi-stage absorption. Each time it is replaced, only the first-stage activated carbon filter plate 5 needs to be replaced, and the subsequent stages of activated carbon filter plates 5 are synchronously moved forward by one level, and then the new activated carbon filter plate 5 is placed at the last stage position to complete the replacement. After the replacement, the adsorption saturation gradient before the replacement can be maintained.

[0043] Among them, a positioning convex strip 502 is provided at the bottom of the activated carbon filter plate 5. A rectangular slot 4021 is provided at the top of the support seat 402. The positioning convex strip 502 and the rectangular slot 4021 are correspondingly matched. The inside of the activated carbon filter plate 5 is hollow and filled with activated carbon particles. An opening is provided at the top of the activated carbon filter plate 5, and a second baffle 501 is detachably installed on the opening. Filter nets 503 are installed on both sides of the activated carbon filter plate 5.

[0044] When installing the activated carbon filter plate 5, directly insert the positioning convex strip 502 at the bottom of the activated carbon filter plate 5 into the rectangular slot 4021 to complete the installation. For disassembly, just pull it out upwards. A rectangular positioning convex ring 504 is fixed on one side of the activated carbon filter plate 5. A rectangular positioning annular groove 505 is provided on the other side of the activated carbon filter plate 5. A rubber sealing ring is provided inside the rectangular positioning annular groove 505. When the adjacent activated carbon filter plates 5 approach each other, the rectangular positioning convex ring 504 is stuck in the rectangular positioning annular groove 505 to complete the splicing. The gas will pass through each activated carbon filter plate 5 in turn to achieve the purpose of series absorption.

[0045] Embodiment 2

[0046] Refer to Figures 1-12, The difference between this embodiment and Embodiment 1 is that the support mechanism 4 includes a circulating conveyor belt 401, and support seats 402 are equidistantly arranged on the circulating conveyor belt 401, and the circulating conveyor belt 401 is elastically connected to the support seats 402. A slide rail 403 is fixed at the top of the circulating conveyor belt 401. The extending direction of the slide rail 403 is parallel to the conveying direction of the circulating conveyor belt 401. A slider 404 is installed at the top of the slide rail 403, and the support seat 402 is fixed at the top of the slider 404. A horizontal guide rod 405 is fixed at the top of the slide rail 403. A guide ring 406 is installed outside the horizontal guide rod 405. The guide ring 406 is fixed to the slider 404, and return springs 407 are sleeved on both sides of the guide ring 406 outside the horizontal guide rod 405;

[0047] When pushing the first-stage activated carbon filter plate 5 and the last-stage activated carbon filter plate 5 from both sides, adjacent activated carbon filter plates 5 can be pushed to approach each other, and finally multiple activated carbon filter plates 5 are tightly connected together. When absorbing tail gas, the tail gas will not flow out from the gaps between adjacent activated carbon filter plates 5. Due to the existence of the return springs 407, when not under force, adjacent activated carbon filter plates 5 will automatically separate, and at this time, it is more convenient to disassemble and assemble the activated carbon filter plates 5. The existence of the circulating conveyor belt 401 further improves the efficiency of replacing the activated carbon filter plates 5. When the first-stage activated carbon filter plate 5 is removed, only need to control the side of the circulating conveyor belt 401 facing the first-stage activated carbon filter plate 5 to move a fixed distance, so that the second-stage activated carbon filter plate 5 reaches the position of the first-stage activated carbon filter plate 5, and then insert a new activated carbon filter plate 5 at the position of the last-stage activated carbon filter plate 5.

[0048] Embodiment 3

[0049] Refer to Figures 1-12 , The difference between this embodiment and Embodiment 2 is that first airtight covers 6 and second airtight covers 602 are respectively arranged on both sides of the inside of the activated carbon filter 2 close to the gas inlet pipe 201 and the exhaust pipe 202. Sleeve pipes 603 are fixed on the sides of the first airtight covers 6 and the second airtight covers 602 away from each other. The two sleeve pipes 603 are respectively movably sleeved outside the gas inlet pipe 201 and the exhaust pipe 202, and two horizontally arranged cylinders 601 are fixed inside the activated carbon filter 2. The output shafts of the two cylinders 601 are respectively fixed to the first airtight cover 6 and the second airtight cover 602;

[0050] When controlling the synchronous elongation of the two cylinders 601, the activated carbon filter plates 5 at all levels can be pushed to approach and combine with each other. After the cylinders 601 contract and reset, the activated carbon filter plates 5 at all levels are separated. The activated carbon filter plates 5 at all levels can ensure that the waste gas enters from the gas inlet pipe 201, enters the interior of the first-stage activated carbon filter plate 5 through the first airtight cover 6 for filtration, then enters the next-stage activated carbon filter plate 5, and finally enters the second airtight cover 602 to gather and then enter the exhaust pipe 202, discharging from the activated carbon filter 2. A gas distributor is provided in the first airtight cover 6.
