CENTRIFUGAL SEPARATOR AND A METHOD FOR CLEANING OF A GAS

摘要

The invention refers to a centrifugal separator and a method for cleaning of a gas containing impurities in the form of solid and/or liquid particles. A stationary casing (1 ) encloses a separation space (2) through which the gas flows. An inlet channel (9) extends to the separation space and forms an inlet for the gas to be cleaned. A rotating member (4) is provided in the separation space (2) downstream the inlet and rotates about an axis (x) 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 (10) is provided downstream the rotating member for discharging the cleaned gas. A first outlet (11 ) is provided for discharging the impurities. A supply member (50) 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.
