SWIRL HEAT EXCHANGE SEPARATOR FOR CLEANING GAS FROM VAPOURS OF ADMIXTURES Russian patent published in 2010 - IPC B04C5/20 F28D7/10 

FIELD: process engineering.

SUBSTANCE: invention is intended for separation and can be used for cleaning gas phase of uranium hexafluoride of admixtures in the form of fluorocarbons. Proposed separator comprises casing with bundle of heat exchange tubes fixed in tube plate, overflow tubes, feed and discharge branch unions and condensate drain union. Overflow tubes are located coaxially inside heat exchange tubes and have free end on the side of lower edges of heat exchange tubes. Gap between free end of overflow tube and lower edge of heat exchange tube makes at least 1.2 and does not exceed 1.5-1.7 of heat exchange tube ID.

EFFECT: stable process characteristics, ease of production and efficient separation.
