Abstract
An exchangeable separation insert for a centrifugal separator includes a rotor casing enclosing a separation space in which a stack of separation discs is arranged, and first and second stationary portions. A feed inlet supplies a fluid mixture to the separation space. The insert includes a light phase outlet and a heavy phase outlet. The feed inlet is arranged at a first axial end of the rotor casing. One of the light phase outlet and heavy phase outlet is arranged at a second axial end. A first rotatable seal seals and connects the feed inlet and a second rotatable seal seals and connects one of the light phase outlet and heavy phase outlet.
Claims20
An exchangeable separation insert for a centrifugal separator comprising:
- a rotor casing enclosing a separation space in which a stack of separation discs is arranged, the rotor casing being arranged to rotate around an axis of rotation;
- a first stationary portion and a second stationary portion, said rotor casing being axially arranged between said first and said second stationary portions;
- a feed inlet for supply of a fluid mixture to be separated to said separation space;
- a light phase outlet for discharge of a separated phase of a first density, and a heavy phase outlet for discharge of a separated phase of a second density higher than said first density, wherein said feed inlet is arranged at a first axial end of said rotor casing (2), and wherein one of said light phase outlet and heavy phase outlet is arranged at a second axial end, opposite the first axial end, of the rotor casing;
- a first rotatable seal for sealing and connecting said feed inlet to a stationary inlet conduit in said first stationary portion;
- and
- a second rotatable seal for sealing and connecting one of said light phase outlet and heavy phase outlet to a stationary outlet conduit in said second stationary portion.
