The Venturi throat is the constricted section of a Venturi scrubber where gas velocity increases and liquid atomization occurs for particulate removal.
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.

Throat sizing depends on required gas flow rate, target pressure drop, particulate loading, and desired removal efficiency. Smaller throats increase velocity and efficiency but also increase pressure drop and energy consumption.
Inspect every 3-6 months for erosion, corrosion, or scaling. High-abrasion applications may require monthly inspections. Throat wear directly impacts scrubbing efficiency.
Yes, with appropriate material selection. Metallic throats can handle temperatures up to 400°C (750°F) with cooling jackets, while plastic throats are limited to 100-150°C (212-302°F) depending on polymer.
