Embodiment 1

[0039] The invention relates to a heating and cooling method for a thermal cycle adsorption separation device. The separation column is immersed in a liquid medium, and the liquid medium is in a flowing state when the liquid medium and the separation column are exchanging heat.

[0040] The device for realizing the method includes a heat exchange pool, which is used to accommodate the separation column; the heat exchange pool is provided with an inlet and an outlet, and the liquid medium is injected into the heat exchange pool through a pump, and the liquid medium enters from the inlet of the heat exchange pool , flows out from the outlet of the heat exchange pool and flows in the heat exchange pool. Through the heat exchange between the liquid medium and the separation column, each part of the separation column is evenly heated.

[0041] When switching between heating and cooling is required, the temperature of the liquid medium can be raised or lowered by heating or cooling ...

Embodiment 2

[0043] A heating and cooling method for a thermal cycle adsorption separation device. In this embodiment, the liquid medium includes a hot liquid medium and a cold liquid medium; Exchange: when the temperature of the separation column is lowered, the cold liquid medium exchanges heat with the separation column. Such as figure 2In the schematic diagram shown, the separation column is located in the heat exchange pool 1, the cold liquid medium 2 and the cooling pump 4 form a cooling component, and are connected to the heat exchange pool 1 through pipelines to form a cooling cycle; the hot liquid medium 3 and the temperature raising pump 5 A heating component is formed and connected to the heat exchange pool 1 through another pipeline to form a heating cycle. The cold liquid medium 2 is circulated in the cooling cycle to realize the cooling of the separation column, and the hot liquid medium 3 is circulated in the temperature raising cycle to realize the temperature rise of the...

Embodiment 3

[0049] The separation column described in this embodiment is a spiral separation column. The length of the helical separation column is longer, which is beneficial to the separation of hydrogen isotopes. At the same time, the heat capacity of the helical separation column is relatively high. Therefore using the figure 2 The shown apparatus implements the method.

[0050] Such as figure 2 As shown, the device includes a heat exchange pool 1, a cold cycle assembly and a heat cycle assembly. A spiral separation column is installed inside the heat exchange tank 1 . The heat exchange tank 1 is a pot-shaped body with upper and lower openings. The cold cycle assembly includes a first cold oil tank 21 and a second cold oil tank 22. The two cold oil tanks are connected to the cooling pump 4 through pipelines, and then connected to the heat exchange pool 1 to form two cold cycle systems. The two cold circulation systems are mutually backed up to meet the requirements of the spir...

Abstract

The invention relates to the field of thermonuclear fusion, in particular to a hydrogen isotope separation technology, and particularly relates to a heating and cooling method of a hydrogen isotope thermal cycle adsorption separation device. According to the method, separation columns are immersed into a liquid medium, and the liquid medium is in a flowing state when the liquid medium exchanges heat with the separation columns. The flowing medium exchanges heat between the separation columns so that on one hand, the temperature of the liquid medium is more uniform, and all parts of the separation columns are uniformly heated; and on the other hand, the flowing medium is kept in a stable high-temperature or low-temperature state so that the heating and cooling speed of the separation columns is higher.

Description

technical field [0001] The invention relates to the field of thermonuclear fusion, in particular to hydrogen isotope separation technology, in particular to a method for raising and lowering the temperature of a hydrogen isotope thermal cycle adsorption separation device. Background technique [0002] Thermal Cycling Absorption Process (TCAP) was first proposed theoretically and conceptually by M.W. Lee of Savannah River Laboratory, and was formally established and put into operation in 1994. The TCAP system is mainly composed of two parts, one is a chromatographic separation column filled with palladium-loaded materials, and the other is an empty column (reflux column), and the upper ends of the two columns are connected by a valve; during separation, the palladium-loaded column is at half-cycle high temperature and half-cycle low temperature in the heating and cooling cycle. In addition to being able to easily separate hydrogen-deuterium and hydrogen-tritium, TCAP can als...
