A Review on Parameters Affecting the Collection Efficiency of Venturi Scrubber

Abstract

The venturi scrubber has been used as air pollution controlling device. These scrubbers are promising device for cleaning the contaminated gases. It is found in the literature that the performance of venturi scrubber (i.e. collection efficiency), is significantly influenced by droplet distribution, pressure drop, disintegration of liquid, droplet sizes and injection methods. Effect of submergence height, multi-stage injection, position of the orifice, diameter of orifice, throat length and angle of convergence and divergence of venturi scrubber is found scarce and these parameters are affecting collection efficiency drastically. Therefore, it is necessary to study their effect to improve the performance of self-priming venturi scrubber. This article is the review of numerical and experimental study of the performance in venturi scrubber.

“…VSs are one of the most effective nozzles that can remove dust particles through contact with water droplets in the throat and diffuser of the nozzle [7]. The self-priming VS has been optimized in several studies to improve its radioactive aerosol or gaseous material removal capacity [8,9]. However, in a wet-type pool scrubber of FCVSs, the VS is usually submerged in the pool water; and the two-phase flow behavior of the pool significantly affects the efficiency of the FCVSs [10].…”
