Use corrosion-resistant alloys or FRP for acidic gas streams. If you'd like to refine your design further, tell me: The type of dust or gas you are scrubbing. Your target emission limit . The available pressure head from your existing fan.
This structure turns a simple spreadsheet into a powerful simulation tool, enabling rapid iteration and optimization of the design. venturi scrubber design calculation xls upd
Convert the calculated pressure drop into required mechanical energy:
What is your target (e.g., PM2.5, PM10)?
You can paste these Excel formulas into your spreadsheet cells (assuming you name your input cells accordingly). (4⋅At)/πthe square root of open paren 4 center

represent boundary layer coefficients derived from experimental fluid dynamics. 4. Particulate Collection Efficiency Prediction
To build a reliable calculation tool, you must define the following input variables: Usually measured in Actual Cubic Feet per Minute (ACFM). Gas Density ( ρgrho sub g ): Critical for pressure drop calculations. Your target emission limit
Function VenturiPressureDrop(V_Throat_FtSec As Double, LG_Ratio As Double) As Double ' Calculates Pressure Drop in inches of water column (in. w.c.) ' Based on simplified Calvert Equation
Venturi scrubbers are highly efficient mechanical separators used to remove fine particulate matter and gaseous contaminants from industrial exhaust streams. Operating on the principle of wet scrubbing, these systems utilize a high-velocity gas stream to atomize a scrubbing liquid into fine droplets. The resulting collision between dust particles and liquid droplets facilitates high-efficiency collection.
Calculate the required throat area based on a target velocity.
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.
