A paint spray booth for removing excess atomized paint from the air in the vicinity of a spray painting operation comprises a spray booth structure having a working or spray painting area, an exhaust chamber and an exhaust stack, which together define an air passage having an inlet at the spray painting area and an outlet at the stack, within which a fan is mounted for drawing air through the inlet and out the outlet at high velocity. A plurality of generally vertical baffles are disposed in the passage between the spray painting area and the exhaust chamber for the purpose of removing overspray or excess atomized paint from the air before it is exhausted out the stack. Mineral oil is continuously flowed over the front surface of the baffles so as to entrain therein paint solids in the air stream, and the oil is received in a reservoir or holding tank wherein the paint solids are allowed to settle, and from which the oil is recirculated for downward flow over the baffles.

A paint spray booth comprising, in combination, an enclosure having side and top walls defining therein a spray painting chamber, an air inlet in one side of said chamber and an air outlet in the other side of said chamber, means for drawing air through said inlet and said chamber and discharging it
A paint spray booth comprising, in combination, an enclosure having side and top walls defining therein a spray painting chamber, an air inlet in one side of said chamber and an air outlet in the other side of said chamber, means for drawing air through said inlet and said chamber and discharging it through said outlet, substantially vertical wall means in said enclosure between said chamber and said outlet extending from side wall to side wall and from top to bottom thereof, said vertical wall means including a plurality of longitudinally spaced sets of vertically extending laterally spaced baffle plates, the baffles plates of the first set having broad front faces exposed to said chamber and forming a rear wall for said chamber against which spray painting operations may be performed, the baffles of said first set being mounted closely adjacent to define narrow vertical slits between said plates for escape of air from said chamber, the baffle plates of each succeeding set being staggered relative to the plates of the preceding set with each plate of each succeeding set being aligned with and laterally broader than a respective one of the spaces between the plates of the preceding set and spaced slightly rearwardly therefrom as to cause air passing through said sets of plates to be diverted into tortuous paths around the plates of each set, the sets of baffle plates succeeding said first set being shorter than the first set and suspended therebehind by an imperforate web coextensive with the upper portions of the baffle plates of the first set, said web equalizing the greater air flow over and through said first set of baffle plates and thus throughout said chamber, an oil reservoir in said enclosure beneath said baffle plates, oil in said reservoir the level in which is spaced below the lower ends of said baffle plates, means between the lower ends of said baffle plates and the oil in said reservoir for prevenTing passage of air below said baffle plates and for constraining the air to pass through said sets of baffle plates, means for continuously pumping oil from said reservoir to the upper ends of the baffle plates of at least the first and second sets and for gravitationally flowing a film of oil uniformly over the front faces of the baffle plates of the first and second sets, whereby particles of paint sprayed against the baffle plates of the first set and carried in the air passage through the slits between the baffle plates of the first set are entrained in the oil and flushed thereby into the reservoir, the oil flowing over said baffle plates being returned to said reservoir and having a free fall from the lower edges of said baffle plates to the level of the oil in the reservoir whereby to cause the entrained paint particles to penetrate the surface of the oil and become immersed therein and to sink to the bottom on the reservoir, the baffle plates of the first set having the side edges thereof bent rearwardly toward the baffle plates of said second set and the baffle plates of said second set having a central concave portion for catching and retaining oil and paint particles passing thereto from the preceding set of plates, the baffle plates of the last set each having the side edges thereof bent forwardly into spaced generally parallel relation with the side edges of the respective plates of the preceding set for catching and retaining oil and paint particles passing thereto from the preceding set, whereby the paint particles are entrained in the oil and deposited in the reservoir and air substantially free of paint and oil particles is delivered to said outlet, and a second baffle system in said enclosure between the last set of said baffle plates and said outlet, said second baffle system comprising a vertical chamber rearwardly of said last set of baffle plates extending from sidewall to sidewall of said enclosure and including a vertical wall spaced rearwardly from said last set of baffle plates and terminating at its lower edge in upwardly spaced relation to the lower ends of said baffle plates to define an entrance into the lower end of said vertical chamber, a pair of laterally spaced baffles converging upwardly from the walls of said vertical chamber above said entrance, and a horizontal deflecting baffle mounted centrally in said vertical chamber above the upper ends of said converging baffles, said horizontal baffle being wider than the space between the upper ends of said converging baffles and having side edges bent downwardly into spaced generally parallel overlying relation with an adjacent one of said converging baffles, said baffles in said vertical chamber causing the air passing therethrough to strike several baffle surfaces and to travel in a tortuous path having several sharp turns therein for removing substantially all traces of paint and oil from the air, said vertical chamber having a bottom wall sloping toward said reservoir for returning to the reservoir all oil removed from the air.
