Designed to suit any process gas requiring particulate removal, the HSA Venturi Scrubber’s classic single venturi design offers maximum scrubber efficiency.
Venturi Scrubbers are used in metalworking, in foundries, in the construction industry, in the mineral processing industry; everywhere, where difficult dusts have to be extracted. Our wet scrubbers perform very well under extreme conditions: if dust is sticky or very moist; if hybrid mixtures occur; if dust contains a lot of sparks; if vapors and mists have to be cleaned of solid particles. Also, if materials are processed where there is a risk of explosion, but fabric filter plants cannot and may not be used.

Operation:

The design of the HSA 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. At the venturi throat, the gas and liquid streams collide and the liquid breaks down into droplets which trap dust particles.
This gas/liquid mixture passes through a flooded elbow, and enters the entrainment separator through a tangential inlet. Centrifugal action removes the heavy wetted particles from the gas stream.
As an alternate, when very large diameter separators are required, the liquid is separated by passing the stream through a chevron-type mist eliminator baffle. The dust/liquid mixture is discharged from the separator bottom drain and the cleaned gas leaves through the top of the separator.

HAS.CO manufactures wet scrubbers for flow volumes from 1,000 m³ to 200,000 m³ per hour

As standard, we equip our round wet scrubbers with three different systems to discharge sludge. We can, however, also design special solution
