Abstract

The invention discloses a hydrogen isotope exchange membrane reaction assembly, comprising a palladium composite membrane tube, a corrugated stainless steel tube and an external sleeve, wherein a thermocouple sleeve is in a threaded connection with one end (close to the corrugated stainless steel tube) of the external sleeve and an osmosis gas outlet is mechanically welded at the other end of the external sleeve; a branch pipe serving as a hydrogen isotope exchange raw gas inlet is arranged at the upper end of the thermocouple sleeve; a tail gas outlet is formed at the upper end of the external sleeve and close to the corrugated stainless steel tube, and a carrier gas He and Q2O raw gas inlet is formed at the lower end of the external sleeve far and is away from the corrugated stainless steel tube. According to the hydrogen isotope exchange membrane reaction assembly disclosed by the invention, a small amount of combined deuterium and tritium can be displaced and separated out by using hydrogen isotope exchange reaction, and a part of products are separated in situ out of the system during reaction, so that very high conversion rate and decontamination factors are obtained, and the recovery rate of deuterium and tritium is improved; the hydrogen isotope exchange membrane reaction assembly can be used for treating high-concentration tritium water and treating plasma ash discharge gas in fusion reaction, and can also be used for industrially producing high-purity hydrogen.

Description

technical field

[0001] The invention relates to a device for treating high-concentration tritium water and plasma ash exhaust gas, in particular to a hydrogen isotope exchange membrane reaction component. Background technique

[0002] Energy and the environment are the basis for human survival and development. With the rapid development of the national economy, people's demand for energy is becoming stronger and stronger. Due to the shortage of fossil fuels and the increasing pollution of the environment, researchers have turned their attention to clean, efficient and controllable thermonuclear fusion energy. During the operation of the fusion device, under certain normal operating conditions (such as cleaning the first wall), a small amount (2-4kg) of very high concentration tritiated water (activity about 1.4×10 6 Ci / kg, close to the stoichiometric ratio of DTO), a small amount of high-concentration tritium water will also be produced under some unexpected conditions (su...
