INLET DEVICE FOR FLUID TANGENTIALLY FED INTO COLUMN Russian patent published in 2012 - IPC B01D3/30 B04C5/04 

FIELD: process engineering.

SUBSTANCE: invention is designed to feed fluid into column. Inlet device is used for tangentially fed fluid that flown through funnel-shaped channel section, nearby column periphery, to be directed into vortex flow. Said vortex flow revolves about axis adjacent to column central axis. Said central axis is aligned with the main direction of fluid flow. One outlet zone of outlet section sets mean fluid flow direction extending along periphery and inclined opposite aforesaid main direction. Channel section central zone, or inlet zone, and mean zone, as well as outlet zone are integrated into diffuser. Edge area of zones integrated into said diffuser and located in inner space adjacent to column periphery extends over less than one half, preferably, less than one third of periphery.

EFFECT: improved feed.
