Abstract

The invention discloses a hydrogen isotope purification filter which comprises an upper shell and a lower shell, wherein a gas inlet is formed in the lower end of the lower shell; a rough filter element and a primary filter element are sequentially arranged in parallel along the gas inlet of the lower shell; a lower flange is arranged at an upper end ring of the lower shell; an annular boss matched with the lower flange is arranged on the upper wall of the lower shell; a secondary filter element is mounted on the annular boss; the secondary filter element is perpendicular to the primary filterelement; an upper flange parallel to the lower flange is arranged at the upper end ring of the upper shell; the lower flange is fixedly connected with the upper flange through a bolt; and a gas exhaust hole is formed in a side of the upper shell. The rough filter element, the primary filter element and the secondary filter element are sequentially arranged in the filter disclosed by the invention, particles and impurity gases are removed through the rough filter element and the primary filter element firstly, and deuterium tritium is separated and recycled through the secondary filter elementsecondly, so that the consequence that the particles and the impurity gases in gases after reactions of deuterium tritium fuel are adsorbed and filter element membrane holes are blocked can be avoided, the separation efficiency can be improved, and the service life of the filter elements can be prolonged.

Description

technical field [0001] The invention relates to the technical field of hydrogen isotope filtration, in particular to a hydrogen isotope purification filter. Background technique [0002] In order to meet the growing energy demand and solve the environmental pollution problems caused by fossil fuels, my country has participated in the International Thermonuclear Fusion Energy Reactor (ITER) program to support related engineering and technical research on fusion reactors. According to the current design, a large amount of deuterium and tritium will be discharged along with the plasma ash exhaust gas. In order to improve the utilization rate of deuterium and tritium and avoid pollution to the environment, plasma ash exhaust gas treatment (TEP) must be carried out to recover the deuterium and tritium. At present, in the existing research on TEP abroad, palladium-based membrane separators are used to separate and recover most of the unreacted deuterium-tritium fuel in the form of...
