[0002] Color coating line mainly realizes coating on the surface of the coating by pre-roll coating or spraying. Solvent-based coating will produce a large amount of organic waste gas (VOC) during the high-temperature curing process. VOC is the abbreviation of volatile organic compounds (volatile organic compounds). The American ASTMD3960-98 standard defines VOC as any organic compound that can participate in atmospheric photochemical reactions. They not only have irritating effects on various organs of the human body, but also have certain toxicity.

[0003] After searching, the existing patent (publication number: CN218608717 U) discloses a high-efficiency V0CS activated carbon filter box, including a support frame, an active support box, a first activated carbon box, a first cleaning auxiliary box, a second activated carbon box, a second cleaning auxiliary box, and a third activated carbon box; the active support box is fixedly connected to the top end surface of the support frame, and the first activated carbon box is arranged at the left end of the active support box; the first cleaning auxiliary box is arranged on the right side of the first activated carbon box. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] In the existing color-coated waste gas treatment, activated carbon is used to adsorb VOC waste gas. Therefore, when replacing the activated carbon particles as a whole, the activated carbon placement frame needs to be opened as a whole each time, and it is impossible to replace it partially. In addition, when adsorbing VOC, the activated carbon on the bottom layer is often the most polluted, while the activated carbon on the upper layer is less polluting. It is impossible to achieve uniform adsorption of VOC by each activated carbon, resulting in the activated carbon particles not being able to fully exert their effectiveness.

[0005] Therefore, in view of the above problems, an adsorption device for treating waste gas from a color coating line is proposed. Utility Model Content
