Handte Vortex Wet Scrubbers

Vortex Scrubbers

Vortex wet scrubbers are used to remove coarse particles with light to medium dust loads from exhaust gas streams of industrial processes. Thereby the wet separators safely handle pollutants like explosive dusts, steel dust or aluminum dust and chips.

Vortex wet scrubbers are used for light to medium dust loads by air flows from 1,200 m³/h up to 60,000 m³/h (700 - 35,000 cfm). They capture and filter pollutants out of the process exhaust air like flammable and explosive dust, steel dust, aluminium, magnesium and titanium chips and dust as well as rubber, leather and plastic fines, fibres, fluff and textile dust or sticky powders.

In Vortex scrubbers - or also known as impingement and entrainment scrubbers - the particle-laden gas impacts on or skims over the surface of the scrubbing liquid which is usually water. Some of the liquid flows through a curved channel, the vortex zone, which creates turbulence and breaks up the liquid into fine droplets. This results in the intimate mixing of the scrubbing liquid droplets with the particle-laden gas. Re-entrainment of particle-laden droplets with clean gas is prevented by droplet separators.

The advantage of this type of wet scrubber is the absence of moving components or spray nozzles, which keeps maintenance costs to a minimum. The particle-laden liquid droplets are separated by lamellae, packing layers or centrifugal separators which are normally an integral part of the wet scrubber. Vortex wet scrubbers are frequently used – in conjunction with special equipment – for the collection of explosive metal dust. Cylindrical versions can be built pressure shock-resistant or pressure-resistant.
