Venturi scrubbers are able to achieve very high particle collection efficiencies, sometimes over 99%. The efficiency is primarily due to contact and absorption.

Dirty exhaust gas enters the Venturi throat section at high velocity and collides with a large volume of tiny liquid droplets. The atomized wash water also reduces wear on the scrubber shell by protecting surfaces from abrasion.

Ejector Venturi Scrubbers can remove gaseous pollutants from many industrial processes. They are effective in removing noxious gases, particulates, odors, and fumes from a variety of applications including cement kiln emissions, basic oxygen furnaces, fly ash removal, coal gasification, industrial and utility boilers and many others. They also have some of the highest particle collection efficiencies of any wet scrubber type, with some exceeding 99%.

Unlike packed towers or plate scrubbers, the ejector venturi design has an open construction that is less prone to plugging and scalding. This makes them one of the most popular types of scrubber for industrial processes such as coal gasification, power generation, petrochemical processing, and waste incineration.

The ejector venturi operates by combining a converging section, throat and diffuser in a single tube. The gas to be treated enters the inlet section where it reaches its maximum velocity, which then drops sharply into the throat section of the scrubber. In the throat section intensive mixing between the gas and liquid takes place, entraining the dust particles into the spray and turning them into fine droplets. The ejector action of the spray at high velocity provides energy to the particles and liquid, which enables them to overcome frictional forces on them and thereby accelerates their escape from the scrubber into a second stage scrubbing chamber.
