In connection with cleaning of gas from particles suspended therein and being heavier than the gas the gas is caused to rotate in a chamber delimited in a stationary housing, so that the particles by centrifugal force are separated from the gas and are thrown towards a stationary housing. The rotation of the gas is accomplished by means of a rotor, which includes a stack of conical separation discs arranged coaxially with each other and concentrically with the rotational axis of the rotor. The gas to be cleaned is caused to flow through interspaces between the separation discs, while they are rotating, the particles by the centrifugal force being brought into contact with the insides of the separation discs. In contact with the insides of the separation discs the particles first move along the generatrices of the separation discs and then move along inclined guiding members, which are arranged in contact with said insides. The guiding members collect particles moving across different sectors of the separation discs and conduct them to separate areas distributed around the surrounding edges of the separation discs. From these areas the particles in an agglomerated or coalesced form are thrown away from the separation discs towards the stationary housing.

Method and an apparatus for cleaning of gas

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.
