example 1

[0049] Example 1: Hydrogen isotope separation in single cycle mode

[0050] In this example, 8 separation columns are selected, namely 1#, 2#, 3#, 4#, 5#, 6#, 7# and 8# separation columns, and each separation column is numbered (1#→2#→...→ 8#→1#) are connected end to end in a clockwise direction to form a closed loop; the turret on which the separation column is placed is placed in a low-temperature tank, and the low-temperature tank is cooled by liquid nitrogen. The separation column on the top of the turret is above the liquid level, and the rest of the The column is submerged below the liquid surface. The example system also includes raw material hydrogen storage tanks, light isotope storage tanks, heavy isotope storage tanks, tail gas storage tanks, flow meters, vacuum pumps, and pipes and valves connecting the above devices.

[0051] The separation column is a stainless steel bellows with an outer diameter of DN50, a wall thickness of 0.2mm, and a length of 1000. The pre...

example 2

[0062] Example 2: Natural Hydrogen Separation in Dual Cycle Mode

[0063] The rotary type low temperature hydrogen isotope separation system selected by example 2 is the same as example 1, and the specific separation method is as follows:

[0064] 1, carry out the operation of step (1)~(6) among the example 1, complete a cycle separation;

[0065] Ⅱ, repeat the operation of step (1)~(6) among the example 1, complete the second cycle separation;

[0066] Ⅲ. Connect the pipeline of the light isotope storage tank, move the rotating frame clockwise, so that the 7# separation column rises out of the liquid surface, the isotope in the column is desorbed, and the light isotope is discharged from the bottom of the column. The concentration is about 1ppm; connect the heavy isotope storage tank pipeline, move the rotating frame counterclockwise, so that the 1# separation column rises out of the liquid surface, and the heavy isotope is discharged from the top of the column. The collecte...

Abstract

The invention discloses a rotary low-temperature hydrogen isotope separation system and separation method, which solves the problem of complex construction, complex parameter control, high operating cost, or complex helium supply, hydrogen-helium separation, and separation column regeneration in the prior art, or palladium Replacement chromatographic media are expensive and prone to failure, among other issues. The separation system includes cryogenic tank, rotary frame, separation column, raw material hydrogen storage tank, light isotope storage tank, heavy isotope storage tank, vacuum pump and tail gas storage tank. The separation method is to desorb the hydrogen isotopes from the liquid nitrogen liquid surface one by one to complete the rearrangement of the hydrogen isotopes in the remaining separation columns; finally collect the light and heavy isotopes from the far and near ends of the loop respectively. The present invention creatively uses the principle of simulated moving bed technology, hydrogen isotopes can circulate continuously in the closed-loop separation circuit, the concentration of heavy isotopes gradually decreases from the near end to the far end where desorption occurs in the separation circuit, and the concentration gradient of heavy isotopes increases with the adsorption / The desorption times increase continuously.

Description

technical field [0001] The invention relates to the application field of nuclear technology, in particular to a rotary low-temperature hydrogen isotope separation system and a separation method. Background technique [0002] Hydrogen isotope separation is one of the core technologies of the fusion reactor deuterium-tritium nuclear fuel cycle. Through isotope separation, not only can a large amount of unburned deuterium-tritium gas be reused in the operation of the reactor, but also the release of tritium to the environment during the operation of the fusion reactor can be realized. effective control of the quantity. To meet the large-scale hydrogen isotope separation requirements for future fusion reactor operations, a series of hydrogen isotope separation technologies have been developed, including low temperature distillation (LHD), low temperature chromatography (GC), and palladium displacement chromatography. [0003] Cryogenic rectification uses the difference in boili...
