Venturi scrubbers are high-efficiency wet collectors that use a converging-diverging duct to accelerate gas streams to high velocities. This velocity difference atomizes liquid drops, creating a massive surface area for capturing fine particulate matter and gaseous pollutants. venturi scrubber design calculation xls upd

The core of the design process focuses on determining the throat velocity and the liquid-to-gas (L/G) ratio. High throat velocities increase the relative velocity between the gas and liquid droplets, which enhances particle collection through inertial impaction. However, this also significantly increases the pressure drop across the system. Key Calculation Parameters
