These vary with temperature and pressure and affect the Reynolds number.
Even a perfectly designed Venturi scrubber requires regular monitoring. Key performance indicators (KPIs) to track in your spreadsheet include the pressure drop stability and the liquid nozzle pressure. An updated design tool should also account for "evaporative cooling" effects if the inlet gas is significantly hotter than the scrubbing liquid, as this affects the actual gas volume inside the throat. venturi scrubber design calculation xls upd
To build an accurate design spreadsheet, several critical variables must be accounted for: These vary with temperature and pressure and affect
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 An updated design tool should also account for
Link the L/G ratio to the pressure drop and calculate the resulting collection efficiency for each particle size fraction.
Enter gas temperature, pressure, moisture content, and particle size distribution.
