What are Venturi Scrubbers?

Venturi Scrubbers are particulate scrubbers that are highly efficient at removing particulate matter (i.e., PM 2.5) emissions from industrial exhaust generated from batch and continuous-type process applications.

Venturi Scrubbers have several advantages compared to filters and other dust collection equipment; not only is the overall size of the equipment often small, but they can handle particle-laden gas streams that are high temperatures or contain moisture.

Other advantages relate to ease of maintenance and choice of construction options; aside from having a system fan and recirculation pump, venturi scrubbers are solid state and have continuous blow-down of the scrubbing liquid & freshwater makeup, which decreases the frequency of cleaning. An additional Clean-In-Place (CIP) manifold system - a series of internal nozzles complete with piping, valving, and chemical injection ports - can integrate to provide further ease of maintenance.

A typical venturi scrubber system incorporates a scrubbing vessel with a venturi throat to facilitate particle collection. Other system components include a system fan, recycle pump, mist eliminator, and exhaust stack.  All Venturi Scrubbers come standard with Pollution Systems' System Automation Controls Packages for minimal operator interface, increased safety, and easy start-up and operation with the touch of a button.

How Do Venturi Scrubbers Work?

Venturi Scrubbers remove PM from dirty exhaust streams by collecting the particulates in liquid droplets. Particle-laden exhaust gas enters the scrubber at high velocity, where it forces into contact with the scrubbing fluid. The liquid separates from the gas due to gravity and the downstream mist eliminator section. The liquid falls into the sump and is collected. A portion of the fluid is removed for disposal and replenished with clean scrubbing fluid for recirculation. The treated air discharges through the stack. Removal efficiency is typically more than 99%.
