Efficiency of packed bed scrubber is significantly influenced by several factors. The scrubber is a Venturi scrubber designed to recirculate water to remove fumes from a gas stream. The Venturi Scrubber uses the differential between high velocity gases and free-flowing water to create droplets which entrap contaminants, hold them in suspension and deliver them as a slurry. Venturi Scrubber Operation The design of the venturi scrubber consists of a “wet approach” venturi followed by a liquid entrainment separator. (10) Equations (1) and (10) give respectively the pressure loss and total number of collection units in a venturi scrubber due to the simplified model used. An important result of this treatment is the prediction of very low pressure drops, if an atomization system giving the “optimum” droplet size (rather than the larger droplet size produced by conventional pneumatic atomization) is used.
