Hydrogen isotope extraction assembly for hydrogen-containing mixed gas under high-temperature conditions

Abstract

The invention discloses a hydrogen isotope extraction assembly for hydrogen-containing mixed gas under high-temperature conditions. The hydrogen isotope extraction assembly comprises an air inlet pipeline, a separation device and a collection pipeline which are connected in sequence; the separation device comprises a proton conductor ceramic membrane; the structures of the two ends of the proton conductor ceramic membrane are the same and are mutually symmetrical; the proton conductor ceramic membrane is provided with a copper electrode cylinder, the upper end of the copper electrode cylinderis provided with a flange electrode slice, the inner side and the outer side of the copper electrode cylinder are sleeved with an inner side insulating cylinder and an outer side insulating cylinder respectively, the upper portion of the inner side insulating cylinder is connected with an upper insulating ring in sleeving mode, the upper end of the inner side insulating cylinder is connected witha copper gasket, and an end flange is arranged on the upper side of the copper gasket. The problems in the prior art that, the temperature difference required for hydrogen separation of hydrogen-containing mixed gas is too large, the requirement for the mechanical property of existing materials is high, and hydrogen prepared through separation contains too many impurities can be solved, the condition requirement is low, the separation efficiency is high, and reliability is high.

Description

technical field [0001] The invention relates to the technical field of isotope separation, in particular to a hydrogen isotope extraction component under high-temperature conditions of hydrogen-containing mixed gas. Background technique [0002] In the era of continuous development of human society, the massive consumption of fossil energy has caused serious environmental pollution. With the advancement of science and technology, hydrogen energy has gradually entered people's field of vision as a new type of clean energy. However, hydrogen is a secondary energy source, and its preparation itself consumes a lot of energy. Therefore, how to extract, separate and utilize hydrogen isotopes from hydrogen-containing mixed gases has become one of the key ways to solve the shortage of hydrogen energy. [0003] Nuclear fusion is generally considered to be the ultimate solution to human energy. The basic principle of nuclear fusion is to use hydrogen isotopes, deuterium and tritium,...
