Description

Technical field: [0001] The invention belongs to the technical field of spray paint waste gas treatment, and specifically relates to a combined process, which realizes the purification of paint spray waste gas through the combined process of deflecting paint mist removal device + pulse bag dust removal + UV photooxidation + activated carbon liquid film absorption and oxidation. Background technique: [0002] During the surface spraying process of mechanical processing, furniture and other industries, paint spraying exhaust gas will be generated. The main pollutants are paint mist particles and volatile organic compounds (VOC). Due to the low concentration of pollutants, it is not suitable to use catalytic combustion process with high purification efficiency. At present, the commonly used treatment process for this part of spray paint waste gas is wet water curtain spraying or dry filter cotton filtration + UV ultraviolet light oxidation + activated carbon adsorption. Existing...
