Designing a venturi scrubber is a complex, iterative process requiring precise fluid dynamics calculations. Using an up-to-date () Excel (XLS) spreadsheet calculation tool is crucial for engineers looking to optimize performance, calculate pressure drops, and size components efficiently. 1. Core Principles of Venturi Scrubber Design

Designing a venturi scrubber is a structured process that balances geometry, fluid dynamics, and operational costs to meet a required efficiency target.

: Efficiency is often modeled using the Yong-Howard correlation , which considers the "impaction parameter" of dust particles into the atomized liquid droplets. Core Calculation Steps for XLS Templates

This document serves as a direct reference for a venturi scrubber design .xls template. It includes input parameters like gas flow rate (e.g., 110,000 ACFM), temperature, and moisture content, and provides calculations for throat velocity, diameter, and section lengths.

Use Excel Data Tables to model how the system performs when factory emissions drop to

You can then use these functions directly in your spreadsheet: =VenturiPressureDrop(300, 5) or =VenturiEfficiency(5, 8, 300, 0.075, 62.4)

An updated () design sheet should go beyond basic sizing by integrating automated verification algorithms:
