[0038] In this embodiment, the waste gas entering the treatment box 1 can be treated by providing a treatment mechanism 2. During the treatment process, the waste gas treatment liquid can be sprayed into the treatment box so that it can react with harmful substances in the waste gas, thereby achieving the purpose of treating the waste gas. During the treatment process, the three-way pipe 26 can be controlled to rotate, which can increase the contact area between the waste gas and the treatment liquid, thereby further improving its efficiency during treatment.

[0039] When in use, the bottom plate 36 is placed in the automobile spray paint room, the treatment box 1 is placed outside the automobile spray paint room, the hose 32 is passed through the automobile spray paint room and is set on the surface of the fixed pipe, and the air pump 31 is turned on during the painting process. After the air pump 31 is turned on, the exhaust gas can enter the interior of the treatment box 1 through multiple air inlet nozzles 35.

When installing, you only need to insert it into the inside of the two installation frames 39. By turning on the first motor 24, the reciprocating threaded rod 317 can be rotated. When the reciprocating threaded rod 317 rotates, the control block 312 can be used to make the lifting box 37 move up and down. When the lifting box 37 moves up and down, the suction range can be expanded. After the exhaust gas enters the interior of the treatment box 1, the liquid pump 23 is turned on. The liquid pump 23 can extract the waste gas treatment liquid into the inside of the three-way pipe 26, and then the treatment liquid can be sprayed inside the treatment box 1 through the two nozzles 28. After the waste gas treatment liquid is sprayed inside the treatment box 1, it can react with the substances in the waste gas, so that the organic particles in the waste gas react with the reagent and then fall into the treatment box 1. The gas after treatment can be discharged into the atmosphere through the exhaust pipe 21. After the treatment is completed, the valve is opened to discharge the waste gas treatment liquid in the treatment box 1, and the impurities in the lifting box 37 can be discharged by pulling open the baffle 319.

Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
