  • Patent number: 9233325
    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.

  • Patent number: 7811347
    Abstract: In a centrifugal separator for cleaning a gas comprising liquid impurities, a stationary casing encloses a separation space having an inner wall surface. The separator comprises an inlet for the gas. A rotating member rotates around and brings the gas to rotation for separation of at least a main part of the liquid impurities from the gas. A gas outlet is provided downstream the rotating member for discharge of the cleaned gas. A first liquid outlet discharges the liquid impurities and comprises an outlet hole. An annular surface extends inwardly from the wall surface and is located downstream the outlet hole. The first liquid outlet comprises an annular shield element extending from the annular surface at a distance and radially inside the outlet hole. The shield element and the annular surface form an annular groove radially inside the outlet hole.

  • Patent number: 6751951
    Abstract: Gases produced by a combustion engine, e.g. crankcase gases, are conducted through a separation chamber formed and surrounded by a centrifugal rotor, by means of which the gases are caused to rotate, so that particles suspended in the gases are separated by means of centrifugal force. The centrifugal rotor is caused to rotate by means of a pressure fluid that is generated by means of the combustion engine.
