Modular centrifugal separator for cleaning gas

Abstract

A centrifugal separator for cleaning gas containing contaminants includes a stationary casing module including a surrounding side wall enclosing a separation space through which a gas flow is permitted, a gas outlet for cleaned gas, and at least one drainage opening for draining separated liquid contaminants from a lower portion of the stationary casing module; a rotating module including a plurality of separation members arranged in said separation space and being arranged to rotate around an axis of rotation; a drive member arranged for rotating the rotating module around the axis of rotation; and an inlet module arranged axially above the stationary casing module, including an inlet pipe for supply of the gas to be cleaned to the inlet module. The inlet module is in fluid contact with the separation space and a liquid outlet module arranged axially below the stationary casing module and configured to permit discharge of liquid contaminants drained from the stationary casing module. The liquid outlet module includes a lower base portion and at least one upwardly extending portion from the lower base portion. The at least one upwardly extending portion extends axially along the surrounding side wall of the stationary casing module such that the liquid outlet module forms an open container into which the stationary casing module is arranged. The liquid outlet module is attached to the stationary casing module via the at least one upwardly extending portion.
