PREDICTION OF VENTURI SCRUBBER PERFORMANCE

The particle collection venturi performance is achieved at the expense of
pressure drop through it. The accurate prediction of pressure drop and
collection efficiency is vital to the optimum design of these systems to achieved
required environmental standards. Per'formance of venturi scrubbers has been
investigated theoretically and expressed in terms of pressure drop and
collection efficiency. The theoretical model comprises simultaneous differential
equations for particle concentration, droplet motion and momentum exchange.
Also in this model the collection efficiency is predicted based on the inertial
impaction, diffusion and interception mechanisms. Pressure drop and collection
efficiency predictions of this model and previous models are compared with
published experimental data. The results show that the present model have
been validated against previously published experimental data and gives
significantly improved predictions compared with the previous models.
