<p>CIRCULAR SPRAY BOOTH Spray particles are removed in at least a 180.degree. surround of an article traversing an arcuate path in the interior of a spray booth. The booth includes a water wash extending vertically for a height greater than the work area and spray area and preferably extends upwardly to the area of an overhead conveyor. Air flow is maintained at a substantially constant velocity to carry overspray particles into the water wash and away from the article and a water particle eliminator eliminates water particles from the cleaned air being discharged. The preferred booth comprises a plurality of adjacent units set at angles to each other to define a polygon of at least 180.degree. with a planar water wash means being provided in each unit. The preferred water wash includes vertically extending t staggered panels each washed with a film of water with the air flowing through gaps between adjacent panels and then flowing down through a second spray water wash. A sludge remover may be used with a water reservoir tank to allow long operation in contrast to the downtime for frequent dry filter replacement and the cost of filter replacement experienced in conventional circular spray booths. A conveyor protection device may be used which discharges positively pressure air from a housing about the conveyor with the air flow in the booth pulling this blown air away from the spray areas and booth portal and into and through the water wash.</p> |
