Scrubber apparatus including improved spray apparatus for fluid dispersion

摘要

The disclosure relates to a new apparatus for fluid dispersion for use in removing particulate matter from air. A spray head or other fluid spray-producing means comprises a rigid spray plate bent to a predetermined configuration with two spray head side plates attached to said spray plate, and two spray head side guide bars attached to said side plates. A pressurized fluid, such as water, is delivered at the bottom of the spray plate whereupon impact with the surfaces of the spray plate, side plates and guide bars causes the fluid to be dispersed in spray form. Through this spray is passed contaminated air containing undesirable particulate matter such as paint overspray, whereupon the air is scrubbed to remove substantially all of the particulate matter. Such a spray head apparatus is typically located at the base of a scrubbing unit connected to a paint spray booth or the like, said scrubbing unit containing baffles through which contaminated air is passed and cleaned prior to emitting the remaining particle-free air to the atmosphere. A diverter apparatus diverts a portion of the fluid spray and directs it toward one or more surfaces of said scrubbing unit to preclude accumulation of the particles thereon.
