The invention relates to a separating body which can be set into rotation for the purpose of separating solid or liquid particles of micron or sub-micron size from a gaseous or a liquid medium, wherein said body consists of a large number of separating ducts with singly connected walls over a part of the axial length, characterized in that the length of at least one of the ducts designated with L, the hydraulic diameter of the duct designated with d and the average axial gas speed in the duct designated with w are chosen in mutual dependence in a manner such that the dimensionless number Lv/(wd<2>) equals at least 0.035, preferably 0.040, wherein v is the kinematic viscosity of the gas. The invention also relates to a rotating particle separator which consists of the above described separating body onto which impellers may or may not be fixed upstream and downstream and wherein the separating body is mounted in a housing which is provided with a medium inlet and medium outlet, optionally with a separate outlet for removing separated particle material. |
