I-PSA ijeneretha ye-oxygen - imishini ekhiqiza umoya-mpilo - ijeneretha ye-oksijini ehlanzekile
Ithangi lokugcina umoya
Umsebenzi wethangi lokugcina umoya ukunciphisa ukushaywa komoya futhi udlale indima yesivikelo;Ngakho-ke, ukuguquguquka kwengcindezi yesistimu kuncishisiwe, futhi umoya ocindezelweyo udlula engxenyeni yokuhlanza umoya ocindezelwe kahle, ukuze ususe ngokugcwele ukungcola kwamafutha namanzi futhi unciphise umthwalo we-PSA eyalandela idivayisi yokuhlukanisa i-oxygen ne-nitrogen.Ngasikhathi sinye, lapho umbhoshongo we-adsorption ushintshwa, futhi uhlinzeka nge-PSA oksijini kanye nedivaysi yokuhlukanisa i-nitrogen enenani elikhulu lomoya ocindezelwe odingekayo ukuze kuthuthukiswe umfutho osheshayo ngesikhathi esifushane, ukuze ingcindezi embhoshongweni we-adsorption ikhuphuke ngokushesha iye phezulu. ingcindezi yokusebenza, ukuqinisekisa ukusebenza okuthembekile nokuzinzile kwemishini.
Idivayisi yokuhlukanisa i-oxygen ne-nitrogen
Kunemibhoshongo emibili ye-adsorption A no-B efakwe isisefo esikhethekile se-molecular.Lapho umoya ocindezelwe ohlanzekile ungena ekugcineni kokungena kombhoshongo A futhi ugeleza ngesisefo samangqamuzana ukuya ekugcineni kokuphuma, i-N2 idonswa yikho, futhi umoya-mpilo womkhiqizo ugeleza uphuma ekugcineni kokuphuma kombhoshongo we-adsorption.Ngemva kwesikhathi esithile, isisefo se-molecular adsorption embhoshongweni A saturated.Ngalesi sikhathi, Umbhoshongo umisa ngokuzenzakalelayo ukukhangiswa, umoya ocindezelwe ube umbhoshongo ongu-B ukuze umunce i-nitrogen nokukhiqizwa komoyampilo, kanye nokuvuselelwa kabusha kwesisefo semolekyuli ye-A.Ukuvuselelwa kwesisefo samangqamuzana kufinyelelwa ngokwehlisa ngokushesha ikholomu ye-adsorption kungcindezi yasemkhathini ukuze kukhishwe i-adsorbed N2.Imibhoshongo emibili i-adsorption kanye nokuvuselelwa ngokushintshana, ukuhlukaniswa komoya-mpilo okuphelele ne-nitrogen, ukuphuma komoyampilo okuqhubekayo.Izinqubo ezingenhla zilawulwa yi-programmable logic controller (PLC).Lapho usayizi wokuhlanzeka komoya-mpilo wokuphela kwe-outlet usethiwe, uhlelo lwe-PLC luzosetshenziselwa ukuvula i-valve yokukhipha umoya othomathikhi futhi kukhiphe ngokuzenzakalelayo umoya-mpilo ongafanelekile ukuze kuqinisekiswe ukuthi i-oxygen engafanelekile ayigelezi endaweni yegesi.Umsindo ungaphansi kuka-75dBA lapho igesi ikhishwa isithulisi.
I-oxygen buffer tank
I-oxygen buffer tank isetshenziselwa ukulinganisa ingcindezi nokuhlanzeka komoyampilo okuhlukaniswe nesistimu yokuhlukanisa i-nitrogen nomoya-mpilo ukuze kuqinisekiswe ukutholakala okuzinzile komoya-mpilo.Ngasikhathi sinye, ngemuva kokushintshwa komsebenzi wombhoshongo we-adsorption, kuzoba yingxenye yegesi yayo emuva kumbhoshongo we-adsorption, ngakolunye uhlangothi ukusiza umbhoshongo we-adsorption ukukhulisa ingcindezi, kodwa futhi ubambe iqhaza ekuvikeleni umbhede, ohlelweni lwemishini yokusebenza idlala i-verPSA generator ye-oksijini isekelwe kumgomo we-adsorption swing swing, ukusetshenziswa kwekhwalithi ephezulu ye-zeolite ye-molecular sieve njenge-adsorbent, ngaphansi kwengcindezi ethile, evela emoyeni ukwenza umoya-mpilo.Ngemuva kokuhlanza nokomisa umoya ocindezelweyo, i-pressure adsorption kanye ne-decompression desorption yenziwa ku-adsorber.Ngenxa yomphumela we-aerodynamic, izinga lokusatshalaliswa kwe-nitrogen ezimbotsheni ze-zeolite molecular sieve liphakeme kakhulu kunelomoya-mpilo.I-nitrogen ithandwa kakhulu ngesisefo se-molecular ye-zeolite, futhi umoya-mpilo uyacetshiswa esigabeni segesi ukuze kwakheke umoya-mpilo ophelile.Ngemva kokuwohloka kokucindezela komkhathi, i-adsorbent desorbed nitrogen nokunye ukungcola, ukuze kuzuzwe ukuvuselelwa.Ngokuvamile, imibhoshongo emibili ye-adsorption isethwe ohlelweni, ukukhiqizwa kwe-oksijeni kwe-adsorption yombhoshongo owodwa, omunye ukuvuselelwa kabusha kwe-desorption yombhoshongo, ngohlelo lwe-PLC lwesilawuli sokulawula ukuvulwa nokuvala i-pneumatic valve, ukuze imibhoshongo emibili ishintshane ukujikeleza, ukuze kuzuzwe inhloso yokukhiqizwa okuqhubekayo kwe-oksijini yekhwalithi ephezulu.Lonke uhlelo luqukethe lezi zingxenye ezilandelayo: umhlangano wokuhlanza umoya ocindezelweyo, ithangi lokugcina umoya, idivayisi yokuhlukanisa umoya-mpilo ne-nitrogen, ithangi le-oxygen buffer;Ukuze ugcwalise amasilinda, i-oxygen supercharger kanye nedivayisi yokugcwalisa ibhodlela ifakwe ekugcineni.y indima ebalulekile yokusiza inqubo.
