CENTRIFUGAL SEPARATOR USING NEGATIVE PRESSURE TO REMOVE HIGHER DENSITY COMPONENTS

摘要

A centrifugal separator 1 comprising a casing 15 which delimits and seals off a first space 18 in which a rotor 2 is arranged. The rotor 2 forms a separation space 7 which is sealed or isolated from the first space 18, and in which separation space 7 centrifugal separation of a higher density and a lower density component from a fluid takes place. An inlet 9 extends into the rotor 2 for introducing fluid to the separation space 7, and a first outlet extends from the rotor 2 for discharge of a component separated from the fluid. The first space 18 is connected to a pump device 20 which is arranged to remove gas, thereby maintaining negative pressure in the space 18. The rotor 2 comprises at least one second outlet 11 extending from the separation space 7 to the space 18 for discharge of at least one higher density component separated from the fluid during operation. A discharge device in the form of a pump is arranged to remove the at least one higher density component separated from the fluid during operation from the space 7
