Venturi Scrubber Design Calculation Xls Upd !!top!! Info

The velocity decreases, allowing for pressure recovery and agglomeration of particles.

A typical L/G range is . Based on your particle size and required efficiency, choose a starting value (e.g., 1.0 L/m³ ). Then:

To facilitate the design calculation process, XLS (Excel) can be used to create a spreadsheet that automates the calculations. The following steps outline the general procedure for performing venturi scrubber design calculations using XLS:

The volume of scrubbing liquid injected. venturi scrubber design calculation xls upd

Flow rates, operating temperatures, dust density, and target efficiency.

Step 4: Pressure Drop Calculation (Yong et al. / Calvert Model) Pressure drop (

A typical target ΔP is between (roughly 5–30 kPa) depending on the application. If your ΔP is too high for the available fan, reduce vt and recheck efficiency. The velocity decreases, allowing for pressure recovery and

Tg = gas absolute temperature

Droplet size is critical for inertial impaction. Use the :
