Mea hana naikokene kiʻekiʻe e pono ai no ka hoʻonui ʻana i nā paipa china mea hoʻoheheʻe nitrogen

I ka piʻi ʻana o ke kaomi ea, e hoʻopaʻa ka sieve carbon molecular i ka nui o ka oxygen, carbon dioxide a me ka maʻa.Ke hāʻule ka puʻe i ke kaomi maʻamau, liʻiliʻi loa ka mana adsorption o carbon molecular sieve i ka oxygen, carbon dioxide a me ka makū.

ʻO ka puʻe kaomi adsorption generator ka mea nui i haku ʻia me ʻelua adsorption hale kiaʻi A a me B i lako me nā kānana molekala kalapona a me kahi ʻōnaehana mana.Ke hele ka ea compressed (he 0.8MPa ke kaomi maʻamau) ma ka hale kiaʻi A mai lalo a luna, hoʻopili ʻia ka oxygen, carbon dioxide a me ka wai e nā molekala kalapona, ʻoiai ke hele ʻia ka nitrogen a kahe mai luna o ka hale kiaʻi.Ke piha ka molecular sieve adsorption i loko o ka hale kiaʻi A, e hoʻololi ia i ka hale kiaʻi B no ka hoʻokō ʻana i ke kaʻina adsorption ma luna aʻe a hoʻoulu hou i ka kānana molekika ma ka hale kiaʻi A i ka manawa like.ʻO ka mea i kapa ʻia he regeneration ke kaʻina o ka hoʻokuʻu ʻana i ke kinoea i loko o ka hale kiaʻi adsorption i ka lewa, no laila e hoʻi koke ke kaomi i ke kaomi maʻamau, a hoʻokuʻu ʻia ka oxygen, carbon dioxide a me ka wai adsorbed e ka molecular sieve mai ka molecular sieve.ʻO ka PSA nitrogen generator enehana he kiʻekiʻe-ʻenehana ikehu-ola hoʻokaʻawale 'enehana i hana pololei naikokene mai ka lewa i ka lumi wela, a ua noi no na makahiki.
