Technology of Dust Vortex Separation from a Gas Flow


The use of the energy of coaxial vortex counter flows for the separation of dust particles from dust-laden flows and the development of efficient fine-dust-trapping plants on this basis. Depending on the dust type, different methods are used to control the aerodynamic activity of the vortex flows.

Innovative Aspect and Main Advantages

Enhanced dust separation efficiency for small-fraction micron particles: separation of dusts smaller than 5 micrometers with an efficiency up to 97 to 98 percent for some dust classes, lower power consumption in comparison with filters and scrubbers, higher recovery of dust materials, and lower environmental impact.

Areas of Application

The chemical industry, the woodworking industry, the iron and steel and the nonferrous-metals industry, the building materials industry, and the power industry.
