CENTRIFUGAL SEPARATOR AND A METHOD FOR CLEANING A GAS

摘要

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.
