Paint mist treatment of water curtain cabinets
Water curtain cabinet is mainly used for the treatment of product coating workshop exhaust gas (paint fog). It mainly circulates water from the suction pump to the water curtain and flows evenly downwards. The exhaust gas (paint mist) from the spray gun was hit by water on the water curtain to the pool below. A small portion of the exhaust gas (paint mist) is discharged from the workshop by the upper fan through the exhaust pipe.
Mainly under the current environmental protection policy, the exhaust gas sprayed needs to go through the water curtain cabinet treatment. Remove the hard-to-handle exhaust gas (mainly paint mist) and the remainder (including a small amount of paint mist and VOCs) and enter the filtration device to filter the paint mist. Then VOCs into the exhaust gas treatment process (photolysis, activated carbon adsorption, RTO or RCO, etc.), by the water curtain cabinet to meet the standard discharge, the market price from 2K / M (excluding expansion) to 1.5w/M, buy a machine with water curtain, put it to achieve the effect of absorbing paint fog, is it true? Not necessarily, first look at the current market of the main types: there are pumps, no pumps and other types!
As for the test results, we made a comparison, with the domestic with pump water curtain of the mainstream cabinet and imported without the pump water curtain cabinet made a comparison (there is no brand writing).
