CENTRIFUGAL SEPARATOR

摘要

The invention refers to a centrifugal separator for cleaning of a gas comprising liquid impurities. A stationary casing (1) encloses a separation space (2) and has an inner wall surface (3). The separator comprises an inlet (9) for the gas to be cleaned. A rotating member (4) rotates around an axis (x) of rotation and brings the gas to rotation in a direction (r) of rotation for separation of at least a main part of the liquid impurities from the gas. A gas outlet (10) is provided downstream the rotating member (4) for discharge of the cleaned gas. A first liquid outlet (11) discharges the liquid impurities and comprises at least one outlet hole (21) extending through the wall surface. An annular surface (20) extends inwardly from the wall surface and is located downstream the outlet hole. The first liquid outlet (11) comprises an annular shield element (22) 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 (23) radially inside the outlet hole.
