Helium refinement and playback method, those applications to production of helium refinement and reproducing arrangement and optical fiber

摘要

This invention regards the method and the device in order to refine impure helium. As for the aforementioned method, low temperature cooling of the impure helium in order to remove at least how much of the main impurities where two continuous processes, (a) that contains helium at least with the cold reduction, and collection of the helium of the intermediate purity which contains the residue of the impurity, and, (b), process in order to remove at least the portion of the residue of the aforementioned impurity (a) from collection of the helium which possesses the final purity which is higher at least than transmission, and the aforementioned intermediate purity of portion of the helium of the intermediate purity which is obtained, there are times when it offers. As for the aforementioned method and the aforementioned device, the refinement helium which can obtain the impure helium which is collected in the exit of the optical fiber cooling chamber, before re-introducing in order to reuse helium to the aforementioned chamber, it is useful in order to refine.
