Isingeniso Somkhiqizo

Inqubo

I-Vacuum Pressure Swing Adsorption (VPSA) I-Oxygen Production Technology isetshenziswa ezimbonini ezihlukahlukene ezifana ne-Iron nensimbi, izinsimbi ezingenayo insimbi, ingilazi, usimende, i-pulp nephepha nokunye.Lobu buchwepheshe busekelwe emandleni ahlukene okukhangisa e-adsorbent ekhethekile eya ku-O₂nezinye izingoma ezisemoyeni.
Ngokwesilinganiso se-oxygen esidingekayo, singakhetha ngokuguquguqukayo i-axial adsorption kanye ne-radial adsorption, inqubo iyavumelana.

Izici Zobuchwepheshe

1. Inqubo yokukhiqiza ingokoqobo futhi ayidli i-adsorbent, impilo ende yesevisi ye-adsorbent enkulu yokukhiqiza umoya-mpilo iqinisekiswa ubuchwepheshe obusebenzayo be-adsorbent bed.
2. Ukuqalisa okusheshayo;ngemva kokuvalwa okuhleliwe noma ukuxazululwa kwezinkinga zokwehluleka ukuvala shaqa okungahleliwe, isikhathi esidingekayo ukuze kuqalwe kabusha kuze kube yilapho ukukhiqizwa komoyampilo ofanelekayo ngeke sidlule imizuzu engu-20.
3. Ukusetshenziswa kwamandla ngokuncintisana.
Ukungcola okuphansi, futhi cishe akukho mfucuza wezimboni olahlwayo.
4. Idizayini ye-modular, izinga eliphezulu lokuhlanganisa, ukufakwa nokulungiswa okusheshayo nokulula, amanani amancane emisebenzi yomphakathi, nesikhathi sokwakha esifushane.

(1) Inqubo Ye-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) I-Equal-Depressurize Process

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 yokuhlanza

Ngemuva kokuqedwa kokulinganisa kwengcindezi, ukuze kuvuselelwe kabusha i-adsorbent enkulu, umbhede we-adsorption ungase ukhishwe ngepompo ye-vacuum ohlangothini olufanayo lwe-adsorption, ukuze kuncishiswe nakakhulu ukucindezela kokungcola okuyingxenye, ukuqeda ngokuphelele ukungcola okukhangisiwe, futhi kuvuselelwe kabusha kakhulu. i-adsorbent.

(4) 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) Inqubo Yokugcina Yokucindezelwa Kwegesi Yomkhiqizo

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.
