Abstract
In a centrifugal separator for cleaning a gas comprising liquid impurities, a stationary casing encloses a separation space having an inner wall surface. The separator comprises an inlet for the gas. A rotating member rotates around and brings the gas to rotation for separation of at least a main part of the liquid impurities from the gas. A gas outlet is provided downstream the rotating member for discharge of the cleaned gas. A first liquid outlet discharges the liquid impurities and comprises an outlet hole. An annular surface extends inwardly from the wall surface and is located downstream the outlet hole. The first liquid outlet comprises an annular shield element extending from the annular surface at a distance and radially inside the outlet hole. The shield element and the annular surface form an annular groove radially inside the outlet hole.
