Method and means for air purification during spray-painting

摘要

A spray-painting chamber comprises a vertical wall containing an upper opening and a lower opening. Means are provided to supply water to the top of said wall so as to produce a film of water running down the wall. Means are provided for sucking the paint mist from the spray-painting chamber through said openings. When passing through said openings the paint mist mixes with the water, resulting in the paint drops being absorbed by the water. Of the total water quantity 30-60% is drawn in by the paint mist through the upper opening. A tank is provided below said wall to receive the water-paint mixture. The paint separates from the water in said tank. The water is re-used by being pumped to the top of said wall.
