A Venturi scrubber consists of three main sections: a converging section, a throat, and a diverging section. The process gas accelerates in the converging section, reaches maximum velocity in the throat where it contacts the scrubbing liquid, and سپس decelerates in the diverging section to recover static pressure.

Venturi scrubbers are high-energy air pollution control devices used to remove particulate matter and hazardous gases from industrial exhaust streams. Designing an effective system requires precise calculations to balance collection efficiency against the energy costs of pressure drop. Fundamentals of Venturi Scrubber Design A Venturi scrubber consists of three main sections:
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
) is the most important factor in determining the operating cost of the scrubber. The most common correlation used in design calculations is the Johnstone equation or the Calvert modification. Pressure Drop Equations The pressure drop ( ΔPcap
