Operation Characteristics of a Venturi Scrubber with Variation of the Diffusor Geometry

Abstract

Venturi scrubbers are used for the separation of solid particles from gases. With the help of this rig, it is possible to separate particles smaller than 1 μ.m in diameter , although it involves a high energy consumption. To reduce the high energy consumption the influence of different diffusor geometries upon the perfomance characteristics, i.e. the pressure drop for equal separation efficiency was investigated. For this purpose experiments were conducted to measure the pressure drop and the grade efficiency for three diffusors by varying the air velocity and the water-air ratio.
