RECTIFICATION PLANT FOR SEPARATION OF ISOTOPES Russian patent published in 2020 - IPC B01D59/04 B01D3/14 F25J3/02 

FIELD: technological processes.

SUBSTANCE: invention relates to a rectification apparatus for separating isotopes and can be used in process of separating isotopes of hydrogen, oxygen, boron (¹⁰B and ¹¹B) and nitrogen (¹⁵N). Proposed plant comprises isotopic exchange section made up of multichannel column accommodating tubes accommodating working channels filled with nozzle, an upper flow reversal assembly, comprising an upper buffer, a condenser and an upper dispenser of a liquid working medium with dispensing tubes, a lower flow reversal assembly comprising a lower buffer, evaporators with working medium feed tubes, a number of which is equal to the number of working channels, heating chamber of evaporators, lower batcher of liquid working medium with dispensing tubes, separators of working medium, number of which is equal to number of working channels, and a flow chamber located in the cavity of the lower buffer, working medium supply pipelines, discharge of the waste product and output of the target product. Each separator includes an inlet chamber located in the cavity of the lower buffer, and a hydraulic gate through which the inlet chamber of the separator is communicated with the flow chamber, wherein the upper part of the inlet chamber is connected to the lower part of the working channel, the lower part of the inlet chamber is connected to the outlet of the evaporator. Dispenser tubes of lower dispenser are connected through hydraulic gates with evaporators. Dispenser tubes of the upper dispenser are connected to upper parts of working channels. Flow chamber inlet is connected to liquid working fluid supply pipeline, outlet of flow chamber is connected with lower metering device cavity.

EFFECT: invention simplifies the design, manufacturing and operation of the plant, improves reliability and stability of operating characteristics, as well as increases service life and efficiency of the plant.
