Umgaqo wokusebenza woxinzelelo lwe-vacuum swing adsorption oxygen Plant (VPSA O2 Plant) kukusebenzisa i-lithium ye-molecular sieve ukukhetha ngokukhethiweyo i-nitrogen emoyeni, ukuze i-oksijini ityetyiswe phezulu kwinqaba ye-adsorption njengemveliso yegesi yemveliso. Yonke inkqubo ibandakanya ubuncinane amanyathelo amabini e-adsorption (uxinzelelo oluphantsi) kunye ne-desorption (i-vacuum, oko kukuthi, uxinzelelo olubi), kunye nokusebenza ngokuphindaphindiweyo kwimijikelezo. Ukuze ufumane imveliso ye-oksijini ngokuqhubekayo, inkqubo ye-adsorption ye-VPSA iyunithi yokuvelisa i-oksijini iqulethwe ziinqaba ezimbini ze-adsorption ezixhotywe nge-molecular sieve (cinga i-tower A kunye nenqaba B) kunye nombhobho kunye neevalve.
Umoya ocinezelweyo uyahluzwa kwaye ube kwinqaba A, emva koko i-oksijini iqokelelwa phezulu kwi-adsorption tower A njengemveliso yegesi yemveliso. Kwangaxeshanye, Tower B ikwinqanaba lokuvuselelwa, xa inqaba A ikwinkqubo adsorption ithande ukuba adsorption saturation, phantsi kolawulo lwekhompyutha, umthombo womoya ujika ibe Tower B kwaye ufake inkqubo yokuvelisa ioksijini adsorption. Iinqaba ezimbini zisebenzisana kumjikelo wokufumana ukuveliswa okuqhubekayo kwe-oksijini.

(1) Inkqubo ye-VPSA O2 Plant Adsorption
Emva kokunyuswa kukuvuthela kweengcambu, umoya wesondlo uya kuthunyelwa ngokuthe ngqo kwi-adsorber apho amacandelo ahlukeneyo (umz. H.2O, CO2kunye noN2) iyakufunxwa ngokulandelelanayo zii-adsorbents ezininzi ukuze ufumane i-O2(ubunyulu bunokulungiswa ngekhompyutha phakathi kwe-70% kunye ne-93%). O2izakuphuma ngaphezulu kwe adsorber, kwaye emva koko isiwe kwitanki yesithinteli semveliso.
Ngokweemfuno zabathengi, iintlobo ezahlukeneyo ze-oxygen compressors zingasetyenziselwa ukucinezela i-oksijini yemveliso ephantsi yoxinzelelo kuxinzelelo olujoliswe kuyo.
Xa umda okhokelayo (obizwa ngokuba yi-adsorption edge ephambili) yendawo yokudluliselwa kobunzima obufunliweyo ufikelela kwindawo ethile kwicandelo elibekelwe indawo yokukhupha ibhedi, ivalve yokungenisa umoya kunye nevalve yokuphuma kwerhasi yemveliso yale adsorber iya kuvalwa. ukuyeka ukufunxa. Ibhedi ye-adsorbent iqala ukutshintshela kwi-equal-pressure recovery kunye nenkqubo yokuvuselela.
(2) Inkqubo yeVPSA O2 Plant Equal-Depressurize Process
Le yinkqubo apho, emva kokugqitywa kwenkqubo ye-adsorption, uxinzelelo oluphezulu lwe-oksijini ephuculweyo yeegesi kwi-absorber zifakwe kwenye i-adsorber yoxinzelelo lwe-vacuum kunye nokuhlaziywa kwakhona kugqitywe kwicala elifanayo le-adsorption Le akuyona nje inkqubo yokunciphisa uxinzelelo kodwa. kwakhona inkqubo yokubuyisela i-oksijini kwindawo efileyo yombhede. Ke ngoko, ioksijini inokubuyiselwa ngokupheleleyo, ukuze kuphuculwe izinga lokubuyisela ioksijini.
(3) Inkqubo yeVPSA O2 Plant Vacuuming
Emva kokugqitywa kokulinganisa koxinzelelo, ukuvuselelwa ngokugqibeleleyo kwe-adsorbent, ibhedi ye-adsorption inokukhutshwa ngempompo yokufunxa kwicala elifanayo le-adsorption, ukuze kuncitshiswe ngakumbi uxinzelelo oluyinxenye lokungcola, ukukhupha ngokupheleleyo ukungcola kwe-adsorbed, kunye nokuhlaziya ngokugqibeleleyo. i-adsorbent.
(4) I-VPSA O2 Plant Equal- Repressurize Process
Emva kokugqitywa kwenkqubo yokucoca kunye nokuhlaziya, i-adsorber iya kunyuswa ngoxinzelelo oluphezulu lwe-oksijini yeegesi eziphuculweyo ezivela kwezinye ii-adsorbers. Le nkqubo ihambelana nokulingana koxinzelelo kunye nenkqubo yokunciphisa, engeyona nje inkqubo yokunyusa kodwa kunye nenkqubo yokubuyisela i-oksijini kwindawo efileyo yezinye ii-adsorbers.
(5) I-VPSA O2 Plant Final Product Gas Repressurizing Process
Emva kwenkqubo ye-Equal-depressurize, ukuqinisekisa ukuba utshintsho oluzinzileyo lwe-adsorber ukuya kumjikelo olandelayo wokufunxa, isiqinisekiso sokucoceka kwemveliso, kunye nokunciphisa uluhlu lokuguquguquka kule nkqubo, kuyafuneka ukunyusa uxinzelelo lwe-adsorber kuxinzelelo lokufunxa kunye. imveliso oksijini.
Emva kwenkqubo engentla, umjikelezo wonke "we-absorption - regeneration" ugqityiwe kwi-adsorber, elungele umjikelezo olandelayo wokufunxa.
Ii-adsorbers ezimbini ziya kusebenza ngokungafaniyo ngokwemigaqo ethile, ukuze kuqatshelwe ukwahlukana komoya okuqhubekayo kunye nokufumana i-oksijini yemveliso.
