The invention relates to a separating body which can be set into rotation to separate solid or liquid particles of micron or submicron size from a fluid, wherein the body has a large number of separating ducts with singly connected walls over a substantial part of the axial length, where the walls of at least one of the separating ducts are not parallel to the axis of rotation. The tangent of the angle between the tangent planes of the walls of the separating duct and the axis of rotation is designated with tan .alpha., the radial width of the separating duct is designated with d, the length of the separating duct is designated with L and the rotation speed of the separating body is designated with .OMEGA. where these variables are chosen in mutual dependence in a manner such that the dimensionless number (.OMEGA.Ld tan .alpha.)/.nu. is located over a substantial part of the separating duct in the range up to 192, wherein .nu. is the kinematic viscosity of the fluid. The invention further relates to a separating unit provided with at least two separating bodies.
A rotatable separating body for separating solid or liquid particles of micron or sub-micron size from a fluid, comprising a plurality of separating ducts including singly connected walls over a substantial part of axial length of said body, wherein said walls of at least one of the separating ducts are not parallel to an axis of rotation of the separating body and that a tangent of an angle between tangent planes of the walls of the at least one separating duct and the axis of rotation designated with tan .alpha., a radial width of the at least one separating duct designated with d, a length of the at least one separating duct designated with L and a rotation speed of the separating body designated with .OMEGA. are chosen in mutual dependence in a manner such that a dimensionless number (.OMEGA.Ld tan .alpha.)/.nu. is located over the length L and the width d of the at least one separating duct in the range up to 192, wherein .nu. is kinematic viscosity of the fluid.
