Paint-spraying booth apparatus

Claim 1

A paint-spraying booth apparatus including: a floor on which, in operation, objects to be spray painted pass, said floor being permeable to air; reservoir means beneath the floor for containing water; a plurality of conduits which converge from inlet to outlet and which extend downwardly from the reservoir means, the reservoir means and the conduits being arranged so that paint-containing air passing through the floor mixes with water from the reservoir means, the resulting mixture passing through the conduit means; impingement means spaced from the outlet of each conduit and disposed so that said mixture flowing through the conduit impinges thereon to perform a first scrubbing action; tubular guard means externally surrounding each conduit and the respective impingement means, to urge said mixture, after contact with the impingment means, (a) to impinge on the respective guard means to perform a second scrubbing action and (b) to travel substantially downwardly, each conduit means and the respective guard means defining therebetween an open-ended passageway debouching adjacent the respective impingement means; first collecting means for collecting a water/paint component of said mixture beneath the guard means; and second collecting means for collecting a substantially paint-free air component of the mixture.
