ABSTRACT:
A system for removing airborne contaminants from the effluent air streams om spray paint booths and the like. The system includes a rectangular shaped underground pool having pool of water positioned below the work area. The underground pool has a plurality of suction pipes which are uniformly distributed throughout the pool at a distance of between one and two inches above the pool of water. The suction pipes terminate in a plenum located adjacent the underground pool. A gas turbine engine which is connected to the plenum is used to draw air including airborne contaminants into the plenum from the work area. Solid airborne contaminants such as droplets of water soluble paint, sand and the like will fall into the pool of water. Lighter airborne contaminants, such as gaseous toxins are drawn through the gas turbine type engine into a after-burning incinerator. At the front end of the after-burning incinerator are a plurality of gas burning elements which supply heat to bed of pebbles which may be quartz, zirconium or high temperature ceramics pebbles. The bed of pebbles incinerates the airborne contaminants within the air streams entering the after-burning incinerator expelling clean air into vertical exhaust stack coupled to the exhaust end of the after-burning incinerator.
