The paper presents a new model for predicting the particle collection performance of venturi scrubbers. It assumes that particles are collected by atomized liquid only in the throat section. The particle collection mechanism is inertial impaction, and the model uses a single drop collection efficiency equation based on the inertial impaction parameter. The model takes the form of an analytic expression for the particle penetration based on particle diameter and venturi scrubber parameters. No arbitrary empirical constants are used. A relation for the maximum throat length necessary for a venturi is also presented. The model is compared with exprimental data from small- and large-scale venturi scrubbers.
