High-Efficiency Venturi Scrubbers
Submicron Particulate & Gas Removal
Venturi HE Scrubbers provide reliable, low-maintenance emission control for fine particulates and gas absorption in high-temperature, variable-flow industrial applications.
Why Choose Venturi HE Scrubbers?
Venturi scrubbers are ideal when you’re dealing with very small particles, including mists and submicron dust, or looking to absorb gases like sulfur dioxide. Their open, streamlined design eliminates the risk of solids buildup, making them easier to maintain over time. Plus, with adjustable or fixed throat options, you get a system tailored to your application’s efficiency and flow requirements.
Venturi HE scrubbers are used for:
• Submicron particle capture
• Acid gas absorption
• High-temperature gas treatment
• Variable gas flow processing
• Multi-industry air pollution control
How Do Venturi HE Scrubbers Work?
At the core of the system is a high-velocity Venturi throat where gas accelerates and mixes with liquid introduced at a 90° angle. This action shatters the liquid into microscopic droplets, which collide with and capture particulates and mists through intense turbulence.
The gas-liquid mixture then enters a Cyclone separator, where centrifugal forces separate out the liquid (and captured solids), draining it for recirculation.
Fixed Throat
The most common design is a fixed throat. For a turndown range of 2:1, the fixed throat is the simplest and lowest cost choice.Variable Throat
For the absolute highest efficiency or for higher turndown, a variable throat is installed which adjusts the cross-sectional area to keep the same pressure drop.Engineered for Performance
