Small-sized tower-shaped combined type waste gas treatment device

Abstract

The invention relates to a small-sized tower-shaped combined type waste gas treatment device. The small-sized tower-shaped combined type waste gas treatment device is a treatment device for construction paint of the painting industry, coating cohesive particles and organic waste gas and is mainly suitable for, but not limited to, waste gas treatment of an automobile finish baking house. The small-sized tower-shaped combined type waste gas treatment device comprises a water curtain type gravity dust collection device, a UV high-energy high-ozone lamplight decomposing device and a honeycomb-shaped square activated carbon adsorption device. The working principle is that a draught fan supplies waste gas generated in the coating process in the automobile finish baking house to a tower-shaped treatment device, gravitational dust collection is conducted through a water curtain, and UV high-energy lamplight decomposition is conducted. In order to increase the treatment speed, the draught fan can be used for feeding the waste gas into honeycomb type activated carbon in the tower-shaped treatment device through secondary pressurization for final adsorption and decomposition, and the waste gas is discharged out from an exhaust port after meeting an emission standard.

Description

technical field [0001] The invention relates to a small tower-shaped combined exhaust gas treatment system, which is a treatment device for construction paint, paint sticky particles and organic waste gas treatment in the coating industry. . Background technique [0002] The pollution emission control of automobile maintenance has become important with the expansion of pollution generated by automobile maintenance, especially the exhaust gas pollution generated by spraying paint. The exhaust gas produced by spraying paint contains a large amount of carcinogens such as paint mist and xylene. The treatment of organic volatile compound solvents produced by spray paint can generally be solved by several methods such as adsorption method, combustion method and decomposition method. Existing equipment that can effectively treat exhaust gas from automobile paint booths has large volume, high cost, high maintenance cost, and high use cost, which is unbearable for the general maint...
