A venturi scrubber is designed to effectively use the energy from a high-velocity inlet gas stream to atomize the liquid being used to scrub the gas stream. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers .

Droplet Separator: Located after the expanding section, this component is designed to separate the contaminant-capturing droplets from the cleaned air. Drainage Hopper: This serves to collect and remove the contaminated liquid. Outlet Nozzle: The purified stream exits through this nozzle.

May 25, 1999 · Venturi scrubbers are primarily used to control particulate matter (PM), including PM less than or equal to 10 micrometers (μm) in aerodynamic diameter (PM 10), and PM less than or equal to 2.5 μm in aerodynamic diameter (PM 2.5).

Venturi Scrubbers are particularly well-suited for separating aerosols and fine dust from gas flows. They are the right choice for particle sizes from approximately 0.7 µm upwards. The particles are separated by impaction on the washing media droplet in the venturi throat.

The design of the MikroPul Venturi Scrubber consists of a “wet approach” venturi followed by a liquid entrainment separator. Dust-laden gases enter the venturi and instantly make contact with the tangentially introduced scrubbing liquid swirling down the venturi’s converging walls.

Every Part.X PV venturi scrubber is engineered to handle high inlet temperatures and process high particulate concentrations, where the required level of particulate removal can be attained by applying the correct pressure drop.

The Sly Venturi Scrubber offers a key advantage: better separation and recovery of liquid mists and ultra-fine particulate than other scrubbers. This, along with adjustable pressure drop provisions and energy regain features, combine in our Venturi design to reduce power consumption and maximize efficiency.

The Tri-Mer high-pressure wet venturi scrubber is a well-established technology. Scrubbers with a quench section accommodate high temperature gas streams, including those from casting, sintering, glass manufacturing, incineration, and pyrolysis - and those with high humidity levels.

Venturi Scrubbers bring particulate–laden air streams together with water at high velocities to transfer the particulate into the water stream. The water droplets and particulates are then removed from the air stream through centrifu-gal separation and mist elimination stages.

Cyclonic, mesh-pad, and blade separators are all used to remove liquid droplets from the flue gas and return the liquid to the scrubber water. Cyclonic separators, the most popular for use with venturi scrubbers, are connected to the venturi vessel by a flooded elbow (Figure 8).
