Problems solved by technology

[0003] These exhaust gases need to be treated. If they are not treated, they will be directly released into the atmosphere, which will cause air pollution and affect human health. Most of the existing methods of treating exhaust gases from spray booths use physical treatment methods. The effect is not obvious, and the maintenance cost is high, and it cannot be recycled

Abstract

The invention discloses a treatment system and treatment method for adsorption, concentration and catalytic combustion of waste gas from a paint spraying line. The treatment system comprises a curingoven, a spray booth, a plurality of waste gas treatment modules, a catalytic combustion module and an exhaust module. The treatment method comprises the following steps: S1, waste gas treatment; and S2, acid mist treatment. The invention provides the catalytic combustion treatment system for paint spraying waste gas. According to the system, main pollutants such as VOCs, benzene, methylbenzene, dimethylbenzene, sulfuric acid mist and nitric acid mist existing in paint spraying waste gas are purified; the low-concentration high-air-volume waste gas is concentrated into high-concentration low-air-volume waste gas through an adsorption concentration process; and then the waste gas is treated in a combustion mode. The system can be used for effectively and continuously treating the paint spraying waste gas of factories, so the exhaust gas of each factory meets the national standard in China.

Description

technical field [0001] The invention relates to the field of waste gas treatment equipment systems, in particular to a paint spraying line waste gas adsorption concentration catalytic combustion treatment system and a treatment method. Background technique [0002] In the process of painting equipment in the spray booth, a lot of organic waste gas will be generated, such as: VOCs, benzene, toluene, xylene, sulfuric acid mist and nitric acid mist. [0003] These exhaust gases need to be treated. If they are not treated, they will be directly released into the atmosphere, which will cause air pollution and affect human health. Most of the existing methods of treating exhaust gases from spray booths use physical treatment methods. The effect is not obvious, and the maintenance cost is high at the same time, and it cannot be recycled. Contents of the invention [0004] According to one aspect of the present invention, a paint spraying line waste gas adsorption concentration c...
