Purification tube 4 is filled with adsorption packing material. Purification tube 4 is connected between the outlet end of inlet pipe 2 and the inlet end of outlet pipe 3. The adsorption packing material is activated and regenerated under the backflow of heated gas.

Helium enters the purification pipe 4 through the inlet pipe 2, and other impurities in the helium are adsorbed by the adsorption packing material inside the purification pipe 4. The helium then enters the high-concentration helium collection device through the outlet pipe 3, completing the helium purification process. This process can purify 5N carrier helium to the 8N level or higher, meeting the requirements for high-concentration helium use and thus helping to reduce helium usage costs. The adsorption packing material is periodically activated and regenerated.

This helps to extend the service life of the adsorption packing and reduce the cost of use. The adsorption packing can be an alloy porous material, mainly composed of various alloy porous materials such as silicon (SiO2), aluminum (Al2O3), sodium (Na2O), and calcium (CaO).
