ABSTRACT:
An air scrubber employing means which cause the air entering the scrubber to follow a circular path is provided for removing solid, liquid and gaseous contaminants from air. Removal is through a liquid contact system in which slow-moving contact with cleaning water is alternated with intimate turbulent contact. The circular motion continues by itself through multiple stages. The circular air flow travels in a generally downward direction through a multiplicity of stages to a water and contaminant receiving tank and then the air and some water are drawn upwardly through an internal co-axial outlet of expanding diameter so that only the air is removed.
It will be noted that the scrubbing unit of this invention serves to provide multi-stage contact between the liquid and the contaminated air in which there are alternately slow-moving circular motions followed by high-speed turbulent compressive actions providing for the greatest possible admixture.
