Air washer

Claim 1

In an air washer, a vertical cylindrical housing, a water collection pool in the lower portion of said housing, a tangential air inlet above said collection pool, an inlet baffle plate mounted in said inlet and adjustable to vary the degree to which inlet air is deflected downwardly against the surface of the collection pool, an annular water seal spaced inwardly from said housing and extending into said pool, a set of circularly arranged vertical impingement baffles defining openings therebetween extending from and positioned above said seal, an annular plate extending between the upper ends of said impingement baffles and the housing whereby air will flow radially inwardly through said impingement baffles, means for maintaining a constant spray film of water on said impingement baffles comprising a pipe extending into said housing and upwardly through the center of said seal, the upper end of said pipe being centrally located within said impingement baffles, means for supplying water under pressure into said pipe, an inverted conically shaped distributor mounted above the exit of said pipe, a dished distributor plate above said distributor and extending outwardly therefrom, whereby water issuing from said pipe will be deflected radially outwardly and downwardly by said distributor and distributor plate onto said impingement baffles, an annular opening being formed between said distributor plate and said first-mentioned plate so that the air flowing through said impingement baffles will pass upwardly therethrough, moisture eliminator baffles in said housing above said annular opening, and a fan above said moisture eliminator baffles drawing air through said housing and discharging the air therefrom.
