Device for recycling gas purified from spray paint waste gas in spray room

Abstract

The invention discloses a device for recycling gas purified from spray paint waste gas in a spray room, which can effectively reduce and eliminate volatile organic compounds, ensure that waste gas in the spray room is purified and the purified gas can be recycled, and realize zero discharge of waste gas after the waste gas undergoes three-stage purification treatment, i.e. water curtain and water spray treatment at the first stage; louver damper steam filtration, coarse paint resistance cotton filtration, active carbon filtration absorption and F7 medium effective filter treatment at the second stage; and apricot shell active carbon absorption and cloth bag dust remove treatment at the third stage. The device with novel structure is provided with a wastewater disposal basin and a circulation water basin at the lower part of the spray room and also provided with a second-stage and third-stage waste gas treatment device at the upper part of the spray room and has the advantages of small floor area, high waste gas treatment efficiency and recycled purified gas; and after filtration treatment, wastewater can be recycled and centrically treated. Double-zero discharge of waste gas and wastewater is realized; and effects of land saving, environment protection, energy saving and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a device for purifying and recycling air of waste gas in a paint spray booth, which can effectively reduce and eliminate volatile organic compounds, so that the exhaust gas in the paint spray room can be purified and the purified air obtained can be recycled , to achieve zero exhaust emissions. Background technique [0002] Spray paint generally contains toxic and harmful substances such as benzene, toluene, xylene, etc. The exhaust gas of spray paint in the spray booth has a large concentration and content of toxic and harmful substances, and there are a large number of carcinogens. If it is not effectively purified and controlled, It will endanger the health and life safety of spray painting operators; if the toxic and harmful spray paint exhaust gas is discharged directly outward, it will pollute the environment and cause public nuisance to people....

AI Technical Summary

Problems solved by technology

[0003] At present, there are many treatment equipment and methods for spraying exhaust gas in spray booths at home and abroad, but there are not many to achieve a better effect of spraying exhaust gas. It is necessary to become purified air after the exhaust gas is treated and then recycled to achieve zero emission of exhaust gas. undiscovered
