Scrubbers ejector-venturi

This type of technology is a part of the group of air pollution controls collectively referred to as "wet scrubbers." Venturi scrubbers are also known as venturi jet scrubbers, gas-atomizing spray scrubbers, and ejector-venturi scrubbers. The technology is based on the removal of air pollutants by inertial and diffusional interception.

Types of equipment classified as spray contactors include countercurrent spray columns, venturi scrubbers, ejectors, cyclone scrubbers, and spray dryers. The use of spray dryers as absorbers is of particular interest in the removal of sulfur dioxide from hot flue gas (see Chapter 7).

Venturi-based reactors work similarly to submerged-jet and ejector reactors, but the big difference is that the liquid is injected into a high velocity gas-phase field, whereas the ejector reactors inject gas into a high velocity liquid-phase field. Hence, the venturi-based reactors create small liquid droplets similar to an atomizer. Venturi-based reactors are used as scrubbers or with quantities of gas phase present in the reactor volume. In contrast, ejector reactors create small bubbles that are used in liquid-phase dominated reactor volumes (Charpentier, 1981).
