A Venturi (or Venturi Scrubber / Venturi Section) is an important component used in industrial air pollution control systems to remove fine dust particles, fumes, and harmful gases from exhaust air streams. It works based on the Venturi principle, where the gas stream is forced through a narrow throat section, causing the velocity of the gas to increase and the pressure to decrease. This high-speed gas flow allows effective mixing of scrubbing liquid with the contaminated air, enabling efficient removal of pollutants. In a typical venturi system, contaminated gas enters the venturi inlet and passes through a converging section, where the cross-sectional area gradually decreases. This causes the gas velocity to increase significantly. At the throat section, scrubbing liquid such as water or a chemical solution is injected into the high-velocity gas stream. The intense turbulence created at this point breaks the liquid into very fine droplets, which capture dust particles and absorb harmful gases present in the exhaust.
