The Effect of Ball Diameter on Performance of Wet Scrubber with PVC Balls-Mesh Packing Material

Abstract

Toxic pollutants and harmful flue gases resulting from combustion of fossil fuels in several industries are adversely effecting human and his environment. Packed towers, especially with wire mesh type mist eliminator pads are widely used to entrap these flue gas emissions before they enter into the atmosphere. But clogging of pads during the operation became a big problem which needs replacement with new one every time. The present work motivation is to develop and test, a exhaust fume-wet scrubber with new (PVC) balls-mesh replacing traditional packing material in which the spherical surfaces are going to make only point contact between them. Water (PH Value = 8.7) and lime water (PH Value = 12.3) sprinkled finely in modified air cooler body with 72 nozzles of 1mm in diameter and re-circulated for 100 minutes to purify stationary four stroke diesel engine exhaust. The diameter of the balls used, are varied such as 10cm, 5cm and 2.5cms and drain water samples, for every 20 minutes are collected to check PH values.
