Abstract
An apparatus for cleaning air contaminated by paint sprays through the use of a water wash system. The paint separation compartment comprises a collection plate for directing water droplets into a main water tank, the droplets having paint therein. The apparatus also having mist arrestor and charcoal filters. The contaminated air enters at a lower end of the apparatus and cleansed or purified air is exhausted from the upper end of the apparatus.
Claims17
An apparatus for the treatment of contaminated air, comprising:
- a housing having a lower water containment portion and an upper portion, said upper portion enclosing a plurality of cells and at least one chamber said cells and chamber are defined by baffles;
- a first aperture at the lower end of said upper housing portion for the admittance of contaminated air forming a gas stream;
- a water/air interchange chamber interconnected to said first aperture and connecting said upper housing portion to said water containment portion where said gas stream is water vapor saturated;
- a first cell within said upper housing portion adjacent to and interconnected with said interchange chamber wherein an upward gas stream is present;
- a second cell within said upper housing portion interconnected with and adjacent to said first cell wherein a downward gas stream flow is present;
- said first cell and said second cell comprising a contaminate separation chamber wherein contaminates adhere to water droplets and condensation collected;
- and
- a third cell having a first end and a second and interconnected with said second cell at a lower end thereof at said third cell first end by a third cell first aperture and having a third cell second aperture at said second end for exhaust of said gas stream comprised of purified air.
An apparatus for use in conjunction with a spray paint booth for the removal of contaminates from the air, comprising:
- a water filtration system for the exhausts of said spray booth including a main water holding tank at the base of said apparatus and an upper housing enclosing a plurality of cells and at least one chamber said cells and chamber defined by baffles;
- means for drawing air into said apparatus;
- a first aperture in said housing for the admittance to the apparatus of contaminated air;
- said main water holding tank adjacent said first aperture having an open upper surface across which said contaminated air passes;
- an upward flow chamber and a downward flow chamber within said housing comprising a containment separation compartment;
- a collection plate within said containment separation compartment for directing contaminated water droplets to said main tank;
- mist arrestor means at the exit of said containment separation compartment for the formation of water droplets;
- and
- a second aperture in said housing for the exit of purified air from said apparatus.
