Wet scrubbers spray water to absorb dust particles. Then, the dust is absorbed by the water and this will create “dirty water droplets”. Those get collected and are taken away for disposal or recycling, depending on the particular matter.
In the so-called quenching area, raw gas is cooled to its saturation point, while the dust gets absorbed by the water. In the mist collector, the dust-laden and agglomerated drops of “dirty water” are removed by a centrifugal separator. Fine water in the “clean air” can normally be removed in the mist collector as well. The mixture of dust and water can be purified again by additional machinery or simply be recycled in a scrubber in a closed water circuit for water treatment purposes.
