Dust collector and air scrubber

Claim 1

In an air cleaning apparatus for removing solid and particulate matter from a contaminated air stream introduced into the apparatus of the type utilizing an underlying sediment collection tank and a drag conveyor for removing the sediment, that improvement which comprises: (a) an elongate housing having a downwardly extending air inlet at one end and an upwardly extending air outlet at another end downstream of the air inlet, (b) means forming an airflow section horizontally displaced downstream from said inlet in the form of an inverted U, one leg of the U adjacent said inlet receiving air from said inlet, (c) an inverted V-shaped assembly inserted in the U-shaped airflow section in such a manner that the airstream from said air inlet is forced to flow in an upward direction adjacent the one leg and in a downward direction adjacent the other leg, and having spray panels on its respective sides directing water jets transversely of each of said legs in a direction transverse to the flow of the airstream, (d) a water eliminator section displaced downstream horizontally from said U-shaped airflow section and disposed in such a manner that the airstream is forced to flow in a vertically upward direction therethrough, and including two ranks of spaced chevron-shaped baffles extending across said water eliminator section wherein said upwardly moving airstream is forced to flow directly through said baffles in said water eliminator section, and (e) an air moving device spaced horizontally downstream from and below said water eliminator section having an inlet disposed so as to draw the airstream downwardly from said water eliminator section and an outlet disposed to direct the airstream upwardly to said air outlet.
