Abstract: A system includes a sparger and a gas supply for paint sludge separation in a tank containing a mixture of paint and liquid. The tank has an open upper end for moving paint sludge out of the tank. The sparger includes a gas inlet tube fluidically connected to an enclosure hood, the inlet tube projecting downwardly into the tank to a tube outlet. The enclosure hood has a closed upper end that radially encloses the tube outlet and extends downwardly to an open lower end to define an interior volume between the upper and lower ends. The lower end defines a peripheral rim with a diameter greater than a diameter of the enclosure hood at the closed upper end. The gas supply feeds the gas inlet tube of the sparger, and has a pressure that forms a gas pocket within the interior volume of the enclosure hood that extends from the tube outlet to the peripheral rim such that portions of the gas pocket pass over the peripheral rim and form gas bubbles which rise through the mixture towards the open upper end of the tank.

Abstract: A wet scrubber having a body that is molded from a plastic material in combination with a nozzle insert that is removably received in the inlet of the wet scrubber and configured to optimize the speed of fluid flow entering a mixing chamber provided in the wet scrubber. Interchangeable nozzle inserts allow to optimize operation of the wet scrubber for different processes the wet scrubber is operating in conjunction with.

Abstract: A blasting or stripping booth is provided creating a generally downward flow for treatment of fluid and particle flow, which reduces operator exposure to potentially hazardous debris. The booth comprises an enclosure defining an upper region for a workpiece, a lower region, and a separator assembly. In some instances the separator assembly includes individual separator units which are discrete units, each having a generally square or rectangular plan view configuration which are arranged in an array for providing the required process flow capabilities. Further embodiments utilize structures forming the separator which have an elongated trough-like configuration. These embodiments find a particular application in large-scale stripping or blasting booth used in production environments where workpieces may flow through a treatment system in a serial manner. Other suitable applications include batch type processing of parts.

Abstract: A dry filter module adapted for use with a paint spray booth having an under section inlet for conducting a flow of contaminated air and an under section outlet for conducting a flow of filtered air includes at least one movable cart formed with a housing having one or more surfaces for providing a housing inlet and a housing outlet, at least one filter media element arranged within the housing, and at least one seal provided around the one or more surfaces for sealing between the housing inlet and the under section inlet and also between the housing outlet and the under section outlet. The movable cart is operated to move for making contact with the at least one seal between the housing and the spray booth such that the housing of the movable cart and the spray booth are connected and sealed to each other.

Abstract: A spray booth especially adapted for painting operations having a dry filter module with features for allowing changing of the filters quickly and in a contained environment, which reduces exposure to non-authorized and non-properly-protected personnel. A carousel-like filter module flips a wall to move dirty filters into a containment space while placing clean filters in position to continue the painting process. The process and device in accordance with this invention is safe, repeatable, predictable, and capable of changing a large number of filters in a short period of time, for example, during lunch break or other short break in the painting operation.

Abstract: An oil mist collector that is coupled to a machine to receive airborne oil mist generated by the machine. The oil mist collector includes a vortex scrubber in which oil mist particles in the airborne oil mist are removed from the air. The removed oil mist particles are collected and/or recycled back to the machine for reuse. Air from which the oil mist particles have been removed is exhausted through a HEPA filter. A method of removing oil mist particles from airborne mist generated by a machine involves the use of the oil mist collector.

Abstract: A paint spray booth for painting articles is disclosed having a liquid wash scrubber beneath an upper chamber for removing the overspray paint particles from the air by intermixing the paint latent air with a liquid such as water. The scrubber forms a substantially horizontal water and air flow path to reduce the vertical height of the scrubber and therefore reduce the vertical height of the overall spray booth. The scrubber forms a trough extending longitudinally through the booth having a liquid flow exit from the bottom of the trough laterally from the bottom of the trough. Downstream from the trough, a baffle blocks the flow of the liquid forming a liquid trap to create turbulence in the liquid flowing through the scrubber to intermix the liquid with the paint latent air.
