Umgomo wokusebenza we-vacuum pressure swing adsorption oxygen Plant (VPSA O2 Plant) ukusebenzisa isisefo se-lithium molecular ukuze ukhethe ngokukhetha i-nitrogen emoyeni, ukuze umoya-mpilo unothwe phezulu kombhoshongo we-adsorption njengokukhishwa kwegesi yomkhiqizo. Inqubo yonke ihlanganisa okungenani izinyathelo ezimbili ze-adsorption (ingcindezi ephansi) kanye ne-desorption (i-vacuum, okungukuthi, ingcindezi engalungile), futhi umsebenzi uphindaphindiwe ngemijikelezo. Ukuze uthole ngokuqhubekayo imikhiqizo ye-oksijini, isistimu ye-adsorption yeyunithi yokukhiqiza umoya-mpilo ye-VPSA yakhiwe imibhoshongo emibili ye-adsorption ene-sieve yamangqamuzana (thatha umbhoshongo A nombhoshongo B) kanye nepayipi nama-valve.
Umoya ocindezelweyo uyahlungwa bese ufakwa embhoshongweni A, bese umoya-mpilo uqoqwa phezulu kombhoshongo we-adsorption A njengokuphuma kwegesi yomkhiqizo. Ngesikhathi esifanayo, i-Tower B isesigabeni sokuvuselelwa, lapho umbhoshongo A usenqubweni ye-adsorption ijwayele ukugcwala kwe-adsorption, ngaphansi kokulawulwa yikhompyutha, umthombo womoya uphenduka ube umbhoshongo B bese ufaka inqubo yokukhiqiza umoya-mpilo we-adsorption. Le mibhoshongo emibili ibambisana kulo mjikelezo ukuze kuzuzwe ukukhiqizwa komoya-mpilo okuqhubekayo.

| * Idatha yereferensi isekelwe ekuhlanzekeni komoyampilo okungu-90%* Inqubo yokukhiqiza umoya-mpilo we-VPSA isebenzisa idizayini “eyenziwe ngokwezifiso” ngokuya ngokuphakama okuhlukile komsebenzisi, izimo zezulu, usayizi wedivayisi, ukuhlanzeka komoyampilo (70%~93%). | ||||
(1) Inqubo ye-VPSA O2 Plant Adsorption
Ngemva kokukhushulwa isivutheli sezimpande, umoya wokuphakelayo uzothunyelwa ngokuqondile ku-adsorber lapho izingxenye ezihlukahlukene (isb.2O, CO2kanye no-N2) izomuncwa ngokulandelana ama-adsorbent ambalwa ukuze kuqhutshekwe nokuthola i-O2(ubumsulwa bungase bulungiswe ngekhompyutha phakathi kuka-70% no-93%). O2izokhishwa kusukela phezulu kwe-adsorber, bese ilethwa kuthangi lebhafa yomkhiqizo.
Ngokwezidingo zamakhasimende, izinhlobo ezahlukene zama-oxygen compressor zingasetshenziswa ukucindezela i-oksijini yomkhiqizo onomfutho ophansi kumfutho ohlosiwe.
Lapho unqenqema oluphambili (olubizwa ngokuthi i-adsorption lead edge) lwendawo yokudlulisa ubuningi bokungcola okumuncwa lufinyelela endaweni ethile engxenyeni ebekiwe yendawo yokukhipha umbhede, i-valve yokungenisa umoya kanye nevalvu yokukhipha igesi yomkhiqizo yalesi sikhangisi izovalwa. ukumisa ukumuncwa. Umbhede we-adsorbent uqala ukushintshela ekubuyiseleni ingcindezi elinganayo kanye nenqubo yokuvuselela.
(2)Inqubo ye-VPSA O2 Plant Equal-Depressurize
Lena inqubo lapho, ngemva kokuphothulwa kwenqubo ye-adsorption, amagesi anomfutho ophakeme we-oksijini athuthukisiwe ku-absorber afakwa kwenye i-vacuum adsorber ene-vacuum adsorber eqeda ukuvuselelwa ngendlela efanayo ye-adsorption Lena akuyona nje inqubo yokunciphisa ingcindezi kodwa. futhi inqubo yokuthola umoya-mpilo endaweni efile yombhede. Ngakho-ke, umoya-mpilo ungabuyiselwa ngokugcwele, ukuze kuthuthukiswe izinga lokuthola umoya-mpilo.
(3) Inqubo Ye-VPSA O2 Yokuhlanza Izitshalo
Ngemuva kokuqedwa kokulinganisa kwengcindezi, ukuze kuvuselelwe kabusha i-adsorbent enkulu, umbhede we-adsorption ungase ukhishwe ngephampu ye-vacuum ohlangothini olufanayo lwe-adsorption, ukuze kuncishiswe nakakhulu ukucindezela kokungcola okuyingxenye, ukuqeda ngokuphelele ukungcola okukhangisiwe, futhi kuvuselelwe kabusha kakhulu. i-adsorbent.
(4) I-VPSA O2 Plant Equal- Repressurize Process
Ngemva kokuphothulwa kwenqubo yokuhlanza nokuvuselela, i-adsorber izothuthukiswa ngamagesi anomfutho ophezulu we-oksijini avela kwezinye izikhangisi. Le nqubo ihambisana nokulinganisa kwengcindezi kanye nenqubo yokunciphisa, okungeyona nje inqubo yokuthuthukisa kodwa futhi inqubo yokubuyisela umoya-mpilo endaweni efile yabanye abakhangisi.
(5) I-VPSA O2 Plant Final Product Gas Repressurizing Process
Ngemuva kwenqubo ye-Equal-depressurize, ukuze wenze isiqiniseko sokushintshwa okuzinzile kwe-adsorber emjikelezweni olandelayo wokumuncwa, ukuqinisekisa ubumsulwa bomkhiqizo, kanye nokunciphisa uhla lokuguquguquka kule nqubo, kuyadingeka ukukhulisa ingcindezi ye-adsorber kungcindezi yokumuncwa i-oksijeni yomkhiqizo.
Ngemuva kwenqubo engenhla, wonke umjikelezo "wokumuncwa - ukuvuselelwa" uqedwa ku-adsorber, elungele umjikelezo olandelayo wokumunca.
Ama-adsorbers amabili azosebenza ngokuhlukile ngokuya ngezinqubo ezithile, ukuze abone ukuhlukana komoya okuqhubekayo futhi athole umoya-mpilo womkhiqizo.
