Abstract:
A self-powered centrifugal separator comprisinga housing defined by a cylindrical side wall and by a floor shaped to effect drainage of fluid from the housing into a drainage duct,a centrifugal separation rotor, supported with respect to the housing for rotation therein in a predetermined direction about a rotation axis, and arranged to receive fluid at elevated pressure, and to eject the fluid by way of substantially tangentially directed reaction nozzles into the housing, said rotor being supported spaced with respect to the floor of the housing by means of a cage having a central mounting region coupled to the rotor and a surrounding apertured drainage region extending to the housing,and vortex disruption means, operable to inhibit accumulation of ejected fluid within the housing, comprising at least one deflection vane overlying a part of said drainage region in said predetermined direction of rotation of the rotor,said vane having a first edge thereof extending substantially parallel to the cylindrical side wall closer than the spacing between said cylindrical side wall and separation rotor and inclined with respect to said rotation axis in said direction of rotor rotation, and having a second edge extending from an end of said first edge to a location proximate the central mounting region.
