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

The invention discloses an air recycling device for purifying spray paint exhaust gas in a spray paint room. It has three-level purification treatment of exhaust gas. The first level is water curtain and water mist treatment; the second level is louver baffle water vapor filtration, coarse-effect paint-blocking cotton filtration, Activated carbon filter cotton adsorption, F7 medium-efficiency filter treatment, and the third level is apricot shell activated carbon adsorption and bag dust removal treatment, which can effectively reduce and eliminate volatile organic compounds, so that the exhaust gas in the spray paint room can be purified, so that the resulting purified air It can be recycled and achieve zero emission of waste gas. The device of the invention has a novel structure. It is equipped with a waste pool and a circulating pool in the lower part of the spray paint room, and a second and third-level exhaust gas purification treatment are arranged in the upper part. It has a small floor area, high exhaust gas treatment efficiency, purified air can be recycled, and the waste water is filtered. Finally, it can be recycled and processed centrally. Achieve double zero emissions of waste gas and waste water; have the effect of saving land, protecting the environment, saving energy and reducing consumption.
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....
