Advantages of Venturi Scrubber System for Air Pollution Control Waterman Engineers Australia Venturi scrubber systems have high collection efficiencies for particulate pollution, while simultaneously absorbing and neutralizing gaseous pollutants. However, they require large pressure drops leading to higher power requirements. Dirty air enters a Venturi throat and collides with scrubbing water that atomizes the liquid into tiny droplets that encapsulate and collect dust particles through impaction. Wet cyclone scrubbers can also be used to prevent fire hazards by keeping flammable gases wet.
Efficiency of Venturi scrubbers The Venturi scrubber system is one of the most efficient types of wet scrubbing systems available. It is particularly effective in collecting particulate pollutants, but can also treat gases. The dirtiest air coming into a Venturi scrubber is forced at high velocity through the scrubber and collides with scrubbing water. The scrubbing water atomizes to produce a fog of tiny water droplets that capture the pollutant particles through impaction and diffusion. The dirty water then is sucked out of the scrubber and is discharged into a recycle tank or is pumped to a mist eliminator to be cleaned before recirculated back through the Venturi section.

The gas stream entering a Venturi scrubber enters a converging section, then passes through the throat section at an extremely high velocity. The gas then flows through the neck of the Venturi tube, where intensive mixing takes place between the gas and scrubbing liquid. The turbulence created in the throat area allows for maximum particulate and gas removal.
Venturis are often used to remove corrosive and sticky contaminants such as carbon dioxide, sulfur dioxide and hydrocarbons from process streams. They are also ideal for removing volatile organic compounds such as acids, alcohols and ketones from coco roasting and can help facilities operating in Ozone Non-Attainment Zones meet clean air requirements.
