Abstract

A cyclone arrangement for separating particles or droplets from a fluid stream, including at least two cyclones (1, 2, 3; 21, 22, 23), which have a tangential intake opening (4, 5, 6; 24, 25) for the fluid stream and set the fluid stream into rotation so that due to the resulting centrifugal force, particles or droplets to be separated from the fluid stream may be discharged from the cyclone separator through discharge openings (10, 11, 12). A plurality of cyclones are connected in parallel, and the intake openings (4, 5, 6) of the cyclones are closed or opened by a common slider (17; 24), which also has an opening (15, 16, 17; 24, 25) in the vicinity of each cyclone intake opening for passage of the fluid stream. The position and size of each slider opening is designed such that in various slider settings, the fluid stream will reach a different number of cyclone intake openings.
