Abstract

The invention discloses a vacuum gas diaphragm circulating pump for tritium purification. The circulating pump is a micro pump body which has a dual-cavity and double-layer structure, and comprises a bracket, a base, a primary container, a secondary container and a motor. The primary container is fixedly arranged on the bracket; the base is connected with the primary container; the secondary container is arranged on the base; and a first diaphragm cavity structure and a second diaphragm cavity structure which are arranged inside the primary container are bilaterally symmetrical. The motor is arranged in the secondary container. The vacuum gas diaphragm circulating pump can greatly reduce the working pressure of a circulating pump so as to meet the requirement of tritium purification and separation treatment on a lab scale, also can shorten the tritium recovery time, improves the tritium recovery efficiency, reduces the risks of tritium leakage and hydrogen storage bed toxification, and enhances the safety of the tritium treatment process.

Description

technical field [0001] The invention belongs to the technical field of tritium purification devices, in particular to a vacuum gas diaphragm circulation pump for tritium purification. Background technique [0002] Tritium is an important fusion nuclear material. In addition to being used in the first generation of fusion reactors, it is also widely used in other scientific research and military fields. Due to the radioactive decay of tritium, the produced helium-3 is insoluble in metal hydrides, which brings a series of problems to the purification and separation of tritium. Under normal conditions, metal hydrides are used as tritium purification and separation media, and tritium molecules can only reach the surface of metal hydrides through static diffusion. However, due to the blocking and shielding of helium-3, the recovery time of tritium is longer, which increases the risk of tritium leakage and metal hydride poisoning in the system, and greatly reduces the work effic...
