TREATMENT OF SPRAY COATING CHAMBER CIRCULATING WATER AND DEVICE THEREFOR

摘要

PURPOSE: To efficiently recover coating mists from circulating water, to remove malodor and to treat the circulating water and scum at a low cost. CONSTITUTION: Water is supplied to a spray coating chamber 1 with a shower or running water to make the coating mists in the chamber 1 absorbed, and the water polluted with the coating is stored in a lower water tank 8. The water in the lower water tank 8 is introduced into a high-voltage electrolyzer 2, an electric field is impressed on the water, the water passed through the electrolyzer 2 is stored in a flotation tank 4 to float the coating scum, and the water in the flotation tank 4 is returned to the spray coating chamber 1 or the lower water tank 8 and circulated.
