Abstract: A spray booth has an enclosure structure, a ventilation system and overhead lighting. An upper region of the structure defines an air inlet plenum. Air exits the inlet plenum into the work area of the booth through an array of filter elements.

Part of the inflow may be located outboard of the overhead lighting assemblies, and part of the inflow may be located inboard of the lighting assemblies. The overhead lighting assemblies may be spaced apart by a distance that may be greater than the width of objects to be coated in the spray booth, and the lighting assemblies may be canted inward at an oblique angle relative to the horizontal, such that the wash of light from the spaced apart light sources may tend to be convergent.

Abstract: A ventilation system for use, in example, on a spray booth or paint stripping enclosure, in which variable speed fans (or equivalent) are employed, and controlled by a sensor so that the flow rate exhausted from the booth (and directed either to an emission control device or vented to atmosphere) is continually adjusted to minimize the exhaust flow rate from the enclosure. The remainder of the ventilation air is recirculated back into the enclosure. An analyzer located in the recirculation duct continuously monitors the concentration of hazardous constituents present in the recirculation stream, and transmits this data to a central controller, which controls the ventilation fan systems. The central controller controls the recirculation duct and exhaust duct fan systems to achieve the highest recirculation rate possible, yet also maintain constituent concentrations in the recirculation duct at a safe level.

Abstract: An air distribution apparatus in a paint spray booth plenum for increasing the uniformity of down draft velocities from the plenum to the spray booth paint application zone.

Abstract: In the method of the instant invention, volatile organic compounds (VOCs) liberated in the course of solvent-based painting of a workpiece, are recovered. The atmosphere within a closed spray-booth is maintained at a fixed humidity such that vaporized water, supplied in the form of steam or nebulized water vapor, acts as a carrier for VOCs liberated in the course of spray painting or heat curing of a workpiece. The VOCs may be recovered continuously, including during the spray-painting or heat curing of the workpiece. The VOC laden, humidified air is circulated through a condenser such that VOCs dissolved in the water vapor condense and are directed to a recovery means. The water and solvent are separated, recovered and purified for re-use or placed in an appropriate container for disposal, thereby eliminating the usual practice of expelling VOC laden air into the atmosphere. The system is provided with a flame-free heat source to cure the painted workpiece and to guard against the danger of explosion.

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.

Abstract: A method and apparatus for reducing the debris that enters the air inlet of a paint overspray scrubber includes at least an upper collection pond positioned above the air inlet. Lower collection ponds are placed beneath the upper collection pond in horizontally overlapping positions with the upper collection pond so that debris not settling in the upper collection pond will settle in the lower collection pond, providing coverage beneath an entire paint application zone. Debris settling in the collection ponds is removed by providing flush water to rinse the accumulated debris from the collection ponds for removal from the system. Such a system prevents clogging of the air inlet and accumulation of debris on flood sheets in an-air scrubber chamber.

The washer may use the other type washer or a trough for cource of the recirculated water. Preferably, the washer utilizes the floor water from the booth so that the water requirement for the entire booth is very low, say on the order of 40 gallons per minute per foot of booth length, or less, for a booth of a size capable of production line painint of automotive vehicles.
