Uhlelo oluphelele lokuhlukanisa igesi luqukethe izakhi ezifana ne-air compressor, izingxenye zokuhlanza umoya ezicindezelwe, ithangi lokugcina umoya,ijeneretha ye-oxygen yezokwelapha, kanye nethangi le-buffer ye-oxygen.Uma i-cylinder yokugcwalisa idingeka, i-oxygen booster kanye nedivayisi yokugcwalisa ibhodlela kufanele yengezwe.I-compressor yomoya ithola umthombo womoya, izingxenye zokuhlanza zihlanza umoya ocindezelwe, futhi ijeneretha ye-oxygen ihlukanisa futhi ikhiqize umoya-mpilo.Futhi ithangi le-oxygen buffer liphinde libe nendima ebalulekile ohlelweni lwe-PSA.Akuyona nje isitsha, kodwa ingalinganisa ukucindezela nokuhlanzeka komoya-mpilo ohlukaniswe nejeneretha ye-oxygen ukuze kuqinisekiswe ukutholakala kwe-oxygen okuqhubekayo nokuzinzile.

Ukuze uqonde ukubaluleka kwethangi le-buffer, ake siqale ngomgomo wokusebenza we-PSA generator oxygen.Ijeneretha ye-oxygen ye-PSA isebenzisa i-zeolite molecular sieve njenge-adsorbent ukuze ikhangise futhi imunce umoya ocindezelwe ohlanziwe futhi owomile.I-nitrogen ithandwa kakhulu yi-zeolite molecular sieve, ngakho-ke umoya-mpilo uyacetshiswa ukwenza umoya-mpilo ophelile.Khona-ke, ngemva kokuwohloka kokucindezela komkhathi, i-adsorbent desorbe nitrogen nokungcola ukuze kuzuzwe ukuvuselelwa.

Okulandelayo ake sihlaziye izizathu zokuthi kungani amathangi ebhafa kufanele afakwe ku-PSA generator oxygen.Umbhoshongo we-adsorption ushintshwa cishe kanye ngomzuzu, futhi isikhathi sokukhulisa esisodwa siyimizuzwana engu-1-2 kuphela.Uma lingekho ithange lokugcina komoya elinesiviva, umoya ocindezelwe owehluleka ukulashwa uzothwala umswakama kanye nowoyela ngqoijeneretha ye-oxygen yezokwelapha, okuzoholela ekufakeni ubuthi be-molecular sieve, ukunciphisa izinga lokukhiqiza umoya-mpilo, futhi kufinyeze impilo yesevisi yesisefo samangqamuzana.Ukukhiqizwa kwe-oxygen ye-PSA akuyona inqubo eqhubekayo, ngakho amathangi e-oxygen buffer ayadingeka ukuze kulinganiswe ubumsulwa nokucindezela komoya-mpilo okuhlukaniswa nemibhoshongo emibili ye-adsorption ukuze kuqinisekiswe ukutholakala komoya-mpilo okuqhubekayo nokuzinzile.Ngaphezu kwalokho, ithangi le-oxygen buffer lingasiza futhi ukuvikela umbhede ngokushaja kabusha ingxenye yegesi yalo ibuyele kumbhoshongo we-adsorption ngemva kokuba umbhoshongo we-adsorption usushintshelwe ukusebenza.
