Abstract: In a centrifugal separator and method for cleaning of gas containing solid and liquid impurities. A stationary casing encloses a separation space through which gas flows. An inlet channel extends to the separation space and forms an inlet for the gas to be cleaned. A rotating member is provided in the separation space downstream the inlet and rotates about an axis of rotation. The rotating member comprises a number of separation discs and brings the gas to rotate for separating by means of centrifugal forces a main part of the impurities from the gas. A gas outlet channel is provided downstream the rotating member for discharging the cleaned gas. A first outlet is provided for discharging the impurities. A supply member is configured to permit the supply of a separation aid humidifying the particles, which aid is in the form of an aerosol, to the gas to be cleaned.

Abstract: The invention relates to an apparatus (10) for purifying gas while bleeding a crank housing, said apparatus (10) comprising a housing (12) inside which a separator chamber (14) is provided, a rotor arrangement with a rotor shaft (32) that is rotatably mounted in the housing and a centrifugal rotor (39) located in the separator chamber (14), and a fluid driving device (64) for driving the rotor shaft (32) by means of a driving fluid, the driving device (64) being disposed in a driving chamber (60) that is separated from the separator chamber (14) by means of a housing partition (16), and the rotor shaft (32) extending through a breakthrough in the housing partition (16). In the case of this device, it is provided that a labyrinth-type seal (70) is provided in the zone of the breakthrough in order to seal the driving chamber (60) from the separator chamber (14).
