Abstract
The inlet device has a horn-shaped passage piece at a peripheral wall of a column that feeds a fluid tangentially into the column so that the fluid enters into a vortex flow that rotates around an axis adjacent to a central axis of the column. A middle zone and discharge zone of the passage piece are made in the manner of a diffuser and abut the peripheral wall to extends over less than one half of the wall. A discharge zone of the passage piece through which flow takes place presets a middle flow direction of the fluid which extends along the peripheral wall and is inclined against the main direction.
