Patent ID: 10493468

Abstract:
A centrifugal separator for cleaning a gas containing liquid impurities includes a stationary casing including a surrounding sidewall, a first end wall and a second end wall which enclose a space through which a gas flow is permitted. The space includes an upper separation chamber and a lower discharge chamber. The separator further includes an inlet extending through the stationary casing and permitting supply of the gas to be cleaned to the separation chamber, a rotating member including a stack of separation discs and being arranged to rotate around an axis of rotation, wherein the stack of separation discs is arranged in the separation chamber and a drive member for rotating the rotating member. The discharge chamber is arranged axially below the stack of separation discs such that clean gas and separated liquid impurities both enter said discharge chamber after being separated in said stack of separation discs, and further, the separator includes a gas outlet configured to permit discharge of cleaned gas from said stationary casing, wherein the gas outlet includes an outlet opening through the stationary casing and a portion extending from the outlet opening into the discharge chamber. Further, there is a drainage outlet arranged in said discharge chamber and configured to permit discharge of separated liquid impurities from said stationary casing.
