Wet Scrubber is device which work on principle of counter-current by intimating contact of Liquid and Solid (SPM). WET SCRUBBER Efficiently collects dust, odor/bad smells, gas/vapor by mixing liquid with gas containing dusts. For example, some scrubbers may use other chemicals such as lime or magnesium oxide to react with the SO 2 in the flue gas. In all wet scrubbers, the intent is to maximize the surface area of liquid in contact with the exhaust gas to promote SOx absorption in the liquid while still allowing sufficient exhaust flow and complying with the exhaust backpressure limits of the engine or boiler. At the same time, the raw gas is cooled until the saturation point is reached. 8. Wet scrubber is used for all type of fuel. How Wet scrubbers work. Wet Scrubbers; Wet scrubbers force the polluted fumes to pass through a wet limestone slurry which traps sulfur particles. Adding chemical scrubbers that can react with the absorbed natural gases that have a favorable impact on the absorption output has calculation. WORKING PRINCIPLE The fumes smokes and soluble gases such as SO2 and H2S in the flue gases can be removed by using wet type mechanical scrubbers.
