I understand you're looking for an . While I cannot directly provide or host spreadsheet files, I can give you a structured summary report of the key design parameters, typical calculation steps, and where to find updated tools or templates.

Suspended solids in the scrubbing liquid can erode the throat.

Would you like me to provide (without the file) so you can build or update your own Venturi scrubber calculator from scratch?

Venturi scrubbers are highly efficient air pollution control devices used primarily for removing particulate matter and hazardous gases from industrial exhaust streams. Designing an effective system requires precise calculations to balance collection efficiency against energy costs.

The narrowest part where scrubbing liquid (typically water) is injected. The high-velocity gas atomizes the liquid into fine droplets. venturi scrubber design calculation xls upd

Line graphs plotting Throat Velocity vs. Pressure Drop and Particle Size vs. Removal Efficiency to visually optimize the design point.

Designing an effective wet scrubber requires accurate quantification of the incoming gas stream. The physical properties of both the continuous gas phase and the dispersed liquid phase establish the baseline operational constraints. Gas Stream Properties Measured in , this defines the volumetric scale of the equipment. Gas Inlet Temperature ( Tincap T sub i n end-sub ): Expressed in ∘Rraised to the composed with power R

A standard venturi scrubber consists of three main sections: a , a throat , and a diffuser (diverging section) . Gas Flow Rate ( Qgcap Q sub g ): The volume of gas to be treated, typically measured in ACFMcap A cap C cap F cap M Throat Velocity ( I understand you're looking for an

): Calculate the volume of the gas once it has cooled and absorbed water vapor. This volume determines the physical size of the throat.

Pressure drop is the single most critical factor determining the operating cost (fan power) and collection efficiency of the Venturi. The is widely accepted for calculating pressure drop: Would you like me to provide (without the

The pressure drop is the most significant operating cost. The most common formula used in design spreadsheets is the Johnstone equation or the Calvert modification: is an empirical constant specific to the scrubber geometry. 3. Droplet Size Prediction
