The dust-laden gas enters tangentially into the lower compartment of the gas scrubber, creating a cyclonic effect in the flow. Coarse particles are removed by a combination of centrifugal and gravitational forces. The flow then encounters a dirty water slurry descending from the upper compartment, where partial wetting takes place, providing a second stage of cleaning.

As the flow passes through a series of scrubber vanes, medium-sized particles collide with the wet surfaces of the vanes, effectively washing them. The gas stream containing the remaining fine dust is drawn into an adjacent chamber. Atomized spray liquid is sprayed into the eye of the fan, further reducing droplet size. These droplets capture the fine dust particles, thereby enhancing the cleaning efficiency.

The gas flow then enters the upper compartment tangentially at high velocity. Wet agglomerated particles partially adhere to the chamber walls due to the cyclonic effect and flow downwards towards the internal discharge cone. The gas flow without liquid droplets passes through an eliminator located above the scrubber, where the droplets are captured, and the clean gas is discharged to the atmosphere.
