Xls Upd __full__ - Venturi Scrubber Design Calculation

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: 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.

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

Calculate the brake horsepower (BHP) required for the system fan based on the calculated ΔPcap delta cap P and fan efficiency. Maintenance and Optimization The process gas accelerates in the converging section,

Use built-in lookup tables for gas density and viscosity based on the inputs.

These vary with temperature and pressure and affect the Reynolds number. However, this also significantly increases the pressure drop

Enter gas temperature, pressure, moisture content, and particle size distribution.
