Venturi Throat

The Venturi throat is a precisely engineered constriction within a Venturi scrubber system, designed to accelerate contaminated gas streams to high velocities. This acceleration creates intense turbulence and shear forces that atomize injected scrubbing liquid into fine droplets, maximizing gas-liquid contact surface area for efficient removal of particulate matter, aerosols, and soluble gases through inertial impaction, interception, and diffusion mechanisms.

Operates on the Venturi effect: as gas flows through the converging section into the narrow throat, its velocity increases while static pressure decreases. Scrubbing liquid is introduced at the throat inlet, where high-velocity gas shear forces atomize it into micron-sized droplets. Particulates in the gas stream collide with these droplets via inertial impaction and are collected. The mixture then enters a diverging section where velocity decreases, pressure recovers, and droplets containing captured pollutants are separated in a downstream mist eliminator.
