Apparatus and method for cleaning, neutralizing and recirculating exhaust air in a confined environment

摘要

Thermal energy content of exhaust air containing particulate and gas contaminants is withdrawn from a confined environment by a circulation system which liquid scrubs some of the contaminants from the exhaust flow, removes the scrubbing liquid, and then catalyzes or neutralizes gas contaminants into benign gases before discharging the flow back into the confined environment.
