ABSTRACT:
An air pollution control system incorporating a venturi scrubber and a method of cleansing a particulate-laden, contaminated gas flow are disclosed. Spray nozzles are used to introduce optimized droplets of a scrubbing liquid into the venturi to maximize particle collection efficiency. The present invention discloses automatic control systems which adjust the venturi as the properties of the effluent gases change. For example, in one embodiment, the spray volume and/or droplet size is adjusted as the particle concentration changes. In another embodiment, the spray volume is increased as the volume of effluent gas decreases.
