The Rotary Srubber is a high efficiency separator and used for:
The dust laden gas takes a helical path pattern throgh the scrubber from bottom to top. Drop dispersion is initiated by a fast rotating atomizer wheel, using an electric belt drive which is mounted outside the scrubber housing.
The scrubbing liquid is centrically supplied to the guide vanes of the atomizer wheel and accelerated in the guide channels to a thin liquid film. At the outside edge of the wheel the liquid film disintegrates into fine droplets, whose size can be influenced by the wheel speed and liquid quantity. Over the entire cross section of the flow a continous liquid curtain is created. Due to forces of inertia and diffusion, solids and gaseous pollutants in this vortex wash zone are separated.
Particle/droplet agglomerates are forced against the chamber walls and washed down to the sludge outlet. If even higher separation efficiencies are necessary, a second washing section with atomizer wheel or other scrubber equipment can be applied.
