An integrated paint spray booth and air conditioning system and process utilize a spray booth housing, scrubber and filtering chambers located below the housing, and an air conditioning apparatus including an adiabatic saturator. The components are arranged to direct the air flow in the system substantially transverse to the length of the system. The air is conditioned to predetermined psychrometric values by sensing only the temperature of the water entering the saturator and the air exiting the conditioning apparatus.

A rotary valve thermal oxidizer including an interfacial seal disposed between rotating and fixed valve portions to prevent the mixing of treated and untreated gas streams. In a preferred embodiment, the valve sealing device includes a flowable sealing material contained within a receptacle, and contacted by a partition nested within the receptacle. Other sealing devices, as well as purge and/or sealing gases, may be employed to prevent leakage, while avoiding the use of machined parts.

A process for treating paint sludge in which previously cured paint sludge powder is used as a diluent and mixed with wet paint sludge. The paint powder/sludge mixture is agitated and heated to cure the paint sludge. Processing can occur either continuously or in batch mode, and can be accomplished using a mixer charged with heated gases, or a heated mixer.

An apparatus and process for allowing a powder paint system to utilize reclaimed oversprayed powder paint of various colors by collecting it in a common reclaim collector system. The reclaimed powder paint is then applied to a work piece as a base coat to attain a portion of the total film build required. The remainder of the film thickness is then applied in subsequent application of virgin powder paint.

The present invention is directed to a powder paint delivery method and apparatus employing a pressurized reservoir pump that supplies a controlled stream of densely fluidized or dense phase powder paint to the applicator though a powder delivery conduit. The powder flow rate is a function of the pressure in the reservoir and the flow resistance from the reservoir to the applicator, and is therefore very stable over time, and simple to control. The powder flow can be controlled by holding the resistance of the powder flow path constant and varying the pressure in the reservoir, or by holding the reservoir pressure constant and varying the resistance of the powder flow path.
