Air scrubber apparatus

An apparatus for removing particulate from an air stream comprising:

• a housing, said housing having an air intake opening and an opposed air exhaust opening, said housing further including a hopper defining the bottom of said housing, said hopper being of V-shaped configuration;
• means for saturing said air stream with a liquid as it enters said housing for agglomerating said airborne particles with said liquid;
• a first baffle disposed adjacent said air intake opening, and an inner wall member connected to the bottom edge of said first baffle and disposed parallel to and cooperating with a wall of said housing thereby forming a passageway, wherein the saturated air stream impinges on said first baffle and a portion of said liquid-particulate agglomeration is trapped by said first baffle and is channeled directly into said hopper through said passageway;
• a second baffle including a partition section and a trough section, said partition section disposed intermediate and extending generally vertically downwardly from the top of said housing to a point intermediate the height of said housing, said trough section being connected to the bottom end of said partition section and including a pair of conduits in communication with said hopper and disposed along opposed end walls of said housing, with said first baffle being spaced from and overhanging said trough section of said second baffle to create a tortuous S-shaped path for said air stream with said partition section functioning to define a rear open area of relatively large volume adjacent said air exhaust opening;
• a third baffle disposed directly above the apex of said V-shaped hopper acting as a divider to inhibit the air stream from reabsorbing said liquid-particulate agglomeration collected in said hopper;
• and
• means for drawing said air stream into said housing, through said tortuous S-shaped path, said rear open area and out said exhaust opening, whereby the saturated air stream passing said first baffle impinges on said partition section of the second baffle such that another portion of said liquid-particulate agglomeration is trapped by said second baffle and channeled directly to said hopper by said conduits, and whereby after said saturated air stream passes said partition section of said second baffle, the path of said air stream is twisted such that it passes underneath said trough section and above said third baffle and thereafter is further twisted and drawn into said rear open area where said air stream expands such that particulates are removed by gravity from said air stream.
