Wet Scrubber

Working Principle

Wet scrubbers relay on the liquid spray to remove dust particles from the gas stream. It is also for the fume absorption; hence very useful in fume extraction systems. It removes air pollutants by inertia of diffusional impaction, reaction with absorbent or reagent slurry or absorption into a liquid solvent. The inlet gas stream usually enters the bottom of the tower and moves upward, while liquid is sprayed downward from one or more levels.

UNICON Wet Scrubbers are used for removal of noxious and corrosive contaminants from the flue gases generated by various process in process plants. The gas is washed with suitable liquid medium using spray nozzles or atomizers. Suitable packed bed provides large contact surfaces for the gas and liquid to mix and hence traps the contaminants. Low pressure drop and low liquid flow brings down operating costs. Provisions will be made for suitable dosing methods to neutralize the toxic nature of the saturated water before letting out to the atm. The material of construction would be of Mild Steel (MS)/ FRP/SS depending on the application. The packed beds are usually PP/PVC Pal rings, saddles etc to suit the various toxic gases
