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.

Inlet device for a fluid fed tangentially into an apparatus

The fluid inlet device for a column includes an inflow stub and a deflection unit. The deflection unit includes an input zone with a plurality of inlet passages of constant cross-sections that merge into diffuser-like passages formed by curved guide lamellae. The curved guide lamellae diffuse the flow of fluid from the lateral passages laterally and circumferentially of the column to separate a high density phase, such as liquid drops, from a low density phase, such as a gas, under centrifugal force. The curved lamellae also direct the flow of fluid from the central passages downwardly of the column.
