RECTIFICATION UNIT FOR ISOTOPE SEPARATION Russian patent published in 2018 - IPC B01D59/00 B01D59/04 B01D59/28 B01D3/32 F25J3/02 

FIELD: technological processes.

SUBSTANCE: invention relates to distillation unit for separating boron or nitrogen isotopes by rectification methods. Rectification installation comprises multi-channel column, lower flow reversal node including lower buffer and evaporator, upper flow reversing assembly including upper buffer, condenser and dispenser with dispensing tubes. In multichannel column housing, in vertical direction, modules containing horizontal dividing wall are installed in series, and in parallel to tubes forming working channels and discharge tubes arranged in each module with alternating alternation in horizontal plane, number of working channels in each module is equal to number of discharge pipes, and internal diameter of drain pipes is smaller than diameter of working channels. Dividing wall of each module is made with recesses, openings forming inlet parts of discharge tubes made in bottom of recesses, and openings forming nozzle-free input parts of working channels located outside recesses.

EFFECT: invention provides simplification of installation design, reduction in laboriousness of manufacturing and adjusting its elements, increase in reliability and resistance to changes in performance during operation.
