Venturi Exhaust Gas Treatment Scrubber, is a wet dust removal device consisting of a Venturi tube condenser and a mist eliminator (or gas-liquid separator). It uses the Venturi effect (i.e., the gas speed increases and the pressure decreases when passing through a contracting pipe, and the speed decreases and the pressure increases when passing through an expanding pipe) to fully mix the dust-laden gas with the scrubbing liquid (usually water) under the impact of high-speed airflow to achieve dust capture and purification.
