Gas cyclone

belongs to the mostly applied technical separators, because it has applicationwise some fundamental advantages. One of them is certainly the fact that its construction does not show any movable components.

For the large variety of different kinds of dispersed (particulate) phases (for example dust particles, metal chips, wooden waste, liquid droplets) and different gas conditions (pressure, temperature) the lay out and computation of a cyclone is still a complex task.

Suvis has specialised in the development and lay out of cyclone separators and can offer professional solutions and consulting in the area of gas cyclones. Many years of experience gained through numerous cyclone development projects results in optimal solutions for our customers.

A cyclone separator applies centrifugal forces and represents an effective apparatus for separating gas, liquid or solid particles from a continuous phase in chemical, process or environmental engineering. Even though other kind of separators like washers or filters have been continuously developed, cyclone separators are still widely applied since they are robust and insensitive to high pressures and temperatures. Cyclones are used at pressures up to 100 bar and temperatures up to approximately 1200 °C. For the application one has to ensure that the cleanness conditions are fulfilled. Cyclone separators are often applied to free the continuous phase from particles at high temperature or high pressure gas applications or used as a pre separator at high dust concentrations or as an end separator for dust particles which are relatively easy to separate.

Further applications of cyclone separators are the separations of liquid particles (drops) from gases. The figure below shows a schematic of a gas cyclone. The particle laden flow is directed tangentially at the lower part and enters the cyclone. The tangential flow inlet causes a swirl flow inside the cyclone which, in turn, creates centrifugal forces. These relatively strong forces are responsible for the separation. The continuous phase then proceeds upwards in an inner core flow towards the gas exit via the outlet tube.
