Calculate the throat diameter to ensure appropriate velocity for target particle removal.
The volume of scrubbing liquid injected. venturi scrubber design calculation xls upd
To build a reliable calculation tool, structure the Excel workbook across four functional, color-coded sections:
The narrowest point where scrubbing liquid is injected and atomized. Higher pressure drop generally equates to higher collection
Higher pressure drop generally equates to higher collection efficiency for submicron particles, typically ranging from 10 to 50 inches of water column (2.5–12.5 kPa).
): The amount of scrubbing liquid injected per unit of gas. Typical values range from for optimum efficiency. 2. Step-by-Step Calculation Procedure steel manufacturing or waste incineration)
For processes with fluctuating exhaust volumes (e.g., steel manufacturing or waste incineration), a fixed throat area causes massive efficiency drops during low-flow periods. Integrating an adjustable damper blade or plunger mechanism maintains constant throat velocity across changing volumetric loads. Conclusion
When utilizing a calculation sheet for real-world optimization, engineers must balance a fundamental trade-off: .
