Abstract: An air scrubber apparatus is provided for removing particles or fumes from an air stream. The apparatus first saturates the air stream with a liquid and then passes the air stream through a tortuous path defined by an arrangement of three internal baffles. The air stream impinges on two baffles which separate the liquid-particulate agglomeration from the air stream, after which it is directly channeled to a hopper while being shielded from the air stream. Another baffle is provided as a partition between the air flow and the hopper area to inhibit the reabsorption of particles by the air stream. The hopper is of V-shaped configuration which is effective in reducing the turbulence of the air flow around the base of the apparatus. In addition, the V-shaped hopper can accommodate more than one liquid filtering device.

Abstract: A self cleaning apparatus for use in separating material from air in a material-air conveyance system includes an outer housing and a perforated inner housing. A freely pivotable panel member is hingedly mounted on the outer housing, the panel normally being in the open position thus exposing an aperture in the outer housing. When a conveyance cycle is initiated, a downstream blower initially draws air into the system through the aperture in the collector outer housing thus blowing inwardly particles lodged in the perforate inner housing. The negative pressure of the air being thus drawn in the system acts to close the panel member until the conveyance cycle is completed and the downstream blower switched off. The force of gravity then pulls the panel member back to its normally open position until another conveyance cycle is initiated.
