NAPCEN Venturi scrubber is an air pollution control device designed to remove fine particulate matter, gases, and pollutants from industrial exhaust streams. It operates by accelerating contaminated gas through a narrow throat section.The high velocity creates turbulence, breaking the liquid into fine droplets that capture and absorb pollutants. Their key advantage is the ability to handle high-temperature gas streams while simultaneously removing both particulate matter and gaseous pollutants. These scrubbers operate by accelerating contaminated gas through a venturi throat at high velocity, where it interacts with the scrubbing liquid, ensuring effective pollutant removal. Their dual capability of gas cooling and pollutant capture makes Venturi scrubbers a highly reliable and efficient solution for controlling industrial emissions and maintaining air quality.
