Centrifugal separator having a rotor and driving means thereof

A centrifugal separator comprises an inlet for introducing at least one of a gas and gas mixture to be cleaned from particles suspended therein, an outlet for dispensing at least one of a cleaned gas and a cleaned gas mixture, a rotor and a driving means for rotation of the rotor about a rotational axis by means of a gaseous driving fluid,

• the driving means including:
• turbine members connected with the rotor and arranged in a ring around and at some distance from the rotational axis,
• at least one supply member for directing said driving fluid towards the ring of turbine members in a way such that the rotor is brought into rotation about said rotational axis by gradual actuation of the turbine members by the driving fluid, and
• at least one reversing member adapted to receive at least part of said driving fluid having passed through the ring of turbine members and to conduct it back towards the ring of turbine members in a way such that the rotor is once more influenced in its rotational direction by driving fluid thus being reversed;
• wherein the supply member is arranged radially outside the ring of turbine members and the reversing member is arranged radially inside the ring of turbine members.

• and
• wherein the rotor at one axial end has a first portion surrounding the rotational axis and situated at a first radial distance therefrom and a second portion surrounding the rotational axis and situated at a second distance therefrom, said second distance being greater than said first distance and the ring of turbine members being arranged adjacent to and at the same distance from the rotational axis as said second portion.
