Big meaning.
In prior art, the helium purification technique of comparative maturity mainly has low temperature process, high pressure low temperature condensation-adsorption method, membrane separation process.
Low temperature process uses Cryo Refrigerator or the impurity such as liquid nitrogen refrigerating agent freeze and separate nitrogen therein and oxygen to obtain higher degree helium
Gas, purity can reach 99.9995%, and its shortcoming is that separation process needs constantly to provide low-temperature receiver, and observable index is higher, and equipment
Volume is relatively large.High pressure low temperature condensation-adsorption method principle be first carry out under high pressure (10～20MPa), low temperature (77K) cold
Solidifying, to isolate liquid air therein, remove residual impurity by low temperature adsorbent the most again, its shortcoming is that separation process will be
Completing under conditions of high pressure, purification amount consumes relatively large time less.Membrane separation process is to utilize some film to some gas group
Point having the characteristic of selectively penetrating and diffusion, separate and purified gases, it is with the difference of partial pressure of film both sides gas as motive force,
By dissolving, spread, permeating, the step such as desorption, produce what the difference of transfer rate between component realized separating, with traditional
Low temperature process, high pressure low temperature condensation-adsorption method are compared, and owing to operating at normal temperatures, it has the features such as energy consumption is low, convenient to operate,
But the helium purification technique of employing membrane separation process is the most immature.
Chinese invention patent " online purification and the equipment of the useless helium of circulation air conditioner leak detection " (publication number: 104003361A；Open
Day: on August 27th, 2014) in provide a kind of online purification and the equipment of the useless helium of circulation air conditioner leak detection, this equipment includes
