Abstract
A venturi scrubber for cleansing a contaminated gas flow is disclosed. An optimized spray of liquid droplets are injected into the gas flow from one or more nozzles positioned within the throat of each venturi element. The spray is injected counter to the direction of gas flow to increase interactions between contaminant particles and spray droplets. Preferably, hydraulic nozzles are used which emit a hollow cone spray. The spray droplets are preferably in the range of 40-200 microns mean mass diameter (MMD).
