Water curtain type automatic spraying room
The curtain spray booth is a device that uses water to catch paint mist. It is generally composed of an exhaust device, a water supply device, a trapping paint curtain, a shower device, a gas-water separation device, an air passage, and the like.
The basic process of spray painting room to deal with paint mist is as follows: Under the effect of gravity of the exhaust fan, the air containing paint mist flows toward the curtain wall of the inner wall of the curtain spray booth. Part of the paint mist directly touches the water on the curtain wall. The membrane is adsorbed. A part of the paint mist is washed away by the curtain when passing through the water curtain dipped in the curtain panel. The rest of the paint mist not caught by the water film and the water curtain is washed when passing through the water wash area and the wash area. Loss; its combination principle is:
a. Increase the paint mist treatment time, from the lacquer fog escaping work to the fan exhausted several times before processing, to ensure adequate treatment.
b. Increase the chance that the paint mist will be thrown toward the wall of the treatment room or the water surface under the action of gravity, inertial force, centrifugal force, etc., so that the paint mist can be better captured.
c. Increase the chance of contact between water particles and lacquer fog, make the paint fog fully condensed, or make the paint fog adhere to the liquid film or air bubbles, or use the particles as the core to produce dew condensation, so as to improve the paint mist treatment efficiency.
