CENTRIFUGAL SEPARATOR FOR SEPARATING PARTICLES FROM A GAS STREAM

摘要

A centrifugal separator and a method (1) for separation of particles from a gas stream is disclosed. The separator comprises a frame (2), a gas inlet (3) and a gas outlet (4). A centrifugal rotor (5) is arranged to be rotatable in the frame around a rotational axis (x) and comprising a plurality of separation plates (6) defining separation passages (7) between the plates. A central gas chamber (8) in the rotor communicates with a radially inner portion of the separation passages and the gas outlet. A space (9) surrounding the rotor communicates with a radially outer portion of the separation passages and the gas inlet. A device (10) is configured to bring the gas stream in rotation upstream of the rotor. The centrifugal rotor is configured such that the rotational flow of the gas mixture drives the rotation of the centrifugal rotor for separating particles from the same gas stream being conducted from the space surrounding the rotor, through the separation passages between the plates and towards the central gas chamber.
