Centrifugal separator for cleaning gases

A centrifugal separator device for separating solid and/or liquid particles which are suspended in gas media, comprising a rotor which is provided with sedimentation members, which is rotatably mounted in a surrounding, stationary housing and which has a central inlet for the gas medium which is to be cleaned, with the housing having, on the one hand, an outlet for cleaned gas which, during its passage through the sedimentation members in the rotor, has been freed from solid and/or liquid particles, and, on the other hand, an outlet for the solid and/or liquid particles, which are firstly deposited on the sedimentation members and, after that, transferred, by means of a centrifugal force, onto a side wall of the housing, with the outlet for the solid and/or liquid particles having the form of at least one aperture which is included in the side wall of the housing, wherein a number of parallel guide rails which run helically are arranged on the inner side of the housing and extend axially at least over a major part of the length of the rotor and in that the outlet, in the housing, for cleaned gas is located, with respect to the axis, at one end of the rotor while the outlet for the particles which have been collected on the housing wall is located at the opposite axial end of the rotor, with the guide rails being arranged in a direction on the inner side of the housing in relation to the direction of rotation of the rotor which is such that a peripherally outer part of a gas vortex generated by the rotor is forced to entrain the particles which have been collected between the guide rails toward the particle outlet.
