Patent ID: 8066947

Claim:
An air-scrubbing device for eliminating an associated airborne biological and chemical contaminant from an associated volume of air, the air-scrubbing device comprising: a housing including an air inlet and an air outlet; an air inlet port; a conduit attached to the air inlet port and extending to the bottom of the housing; a sparging filter attached to the conduit; an air outlet port of the housing; a liquid drain port of the housing; an alkali inlet port; an airflow pathway initiating approximately at the air inlet port of the housing and terminating approximately at the air outlet port of the housing; a liquid chemical of pH value ranging between 8 and 14, the liquid chemical disposed in the airflow pathway of the housing for exposing the associated airborne contaminant to the liquid chemical; a means of removing airborne liquid particles attached to the air outlet port comprising, a housing containing a coil tube attached to said air outlet port wherein a diameter of the coil tube decreases with respect to the distance away from the air outlet port, creating a venturi separating effect to remove any suspended liquid droplets; a means of maintaining the level of liquid in the housing constant by continuously supplying water to make up the losses such means comprising a float ball, a valve and a conduit attached to a supply of water.
