Abstract

The present invention provides a centrifugal separator bowl (1) comprising a rotor casing (2) enclosing a separation space (17) in which a stack (19) of frustoconical separation discs is arranged to rotate around a vertical axis (X) of rotation, wherein the separation discs are arranged with the imaginary apex pointing to the axially lower end (5) of the rotor casing (2); a feed inlet (20) at the axially lower end (5) for receiving the fluid mixture to be separated; a distributor (24) for distributing the fluid mixture from the inlet (20) to the separation space (17), said distributor (24) being arranged for guiding the fluid mixture to be separated continuously from an axially lower position at the inlet (20) to an axially upper position in the separation space (17). The separator bowl further comprises a light phase outlet (21) for discharge of a separated phase of a first density and a heavy phase outlet (22) for discharge of a separated phase of a second density higher than said first density, said heavy phase outlet (22) being arranged at the axially upper end (6) of the rotor casing (2); at least one outlet conduit (23) for transporting separated phase of the second density from the separation space (17), said conduit (23) extending from a radially outer position of said separation space (17) to said heavy phase outlet (22); said conduit (23) having a conduit inlet (23a) arranged at the radially outer position and a conduit outlet (23b) at a radially inner position.
