Isixhobo esisebenzisa iindlela ezibonakalayo ukwahlula ioksijini emoyeni ukufumana initrogen sibizwa ngokuba yinitrogen generator.Kukho iintlobo ezintathu eziphambili zeejenereyitha zenitrogen, ezizezi, ukwahlukana komoya we-cryogenic, ukwahlukana komoya we-molecular sieve (PSA) kunye noMthetho wokwahlula umoya we-membrane.Namhlanje, umenzi weejenereyitha zenitrogen-HangZhou Sihope technology co.,ltd.iya kuthetha ngokufutshane malunga nomgaqo kunye neenzuzo zoxinzelelo lwe-swing adsorption generation oxygen.

Uxinzelelo lwe-adsorption ye-adsorption yendlela yoxinzelelo, yindlela ye-PSA, kukubhengeza kuxinzelelo oluphezulu ukuphumeza ukwahlukana kwegesi, kunye nokufezekisa ukuvuselelwa kwe-adsorbent kuxinzelelo oluphantsi.Le ndlela isekelwe kwi-molecular sieve ye-adsorption ekhethiweyo yeoksijini kunye namalungu e-nitrogen emoyeni ukuze ahlukanise umoya ukuze ufumane i-oksijini.Xa umoya ucinezelekile kwaye udlula kwinqaba ye-adsorption ene-sieves ye-molecular, iimolekyuli ze-nitrogen zikhethwa ngokukhethekileyo, kwaye iimolekyuli ze-oksijini zihlala kwisigaba segesi kwaye zibe yioksijini.Xa i-adsorption ifikelela kwi-equilibrium, iimolekyuli ze-nitrogen ezifakwe kumphezulu we-molecular sieve zikhutshelwa ngaphandle ngokunciphisa uxinzelelo okanye i-vacuum, kwaye i-adsorption capacity ye-molecular sieve ibuyiselwa.Ukuze unikeze ngokuqhubekayo i-oksijini, isixhobo sivame ukuba neenqaba ezimbini okanye ngaphezulu ze-adsorption, enye inqaba ibhengeza i-oksijini kunye nenye i-desorbs ye-tower, ukwenzela ukufezekisa injongo yokuvelisa i-oksijini eqhubekayo.

Indlela ye-PSA inokuvelisa i-oksijini ngokucoceka kwe-80% -95%.Ukusetyenziswa kwamandla okuvelisa ioksijini ngokuqhelekileyo yi-0.32kWh/Nm3～0.37kWh/Nm3, kwaye uxinzelelo lwe-adsorption luphezulu kunoxinzelelo lwe-atmospheric, ngokubanzi yi-30kPa～100kPa.Inkqubo ilula, isebenza kwiqondo lokushisa, kunye nenqanaba le-automation High, inokuqonda ulawulo olungenamntu, ngakumbi ukhuseleko oluhle.Kwinkqubo ye-vacuum desorption, uxinzelelo lokusebenza lwesixhobo luphantsi, kwaye isitya asilawulwa yinkcazo yesikhongozeli soxinzelelo.Ngokwenani lee-adsorbers, inkqubo ye-adsorption ye-pressure swing yahlulahlulwe ibe yinkqubo ye-one-tower, inkqubo ye-tower-tower, inkqubo ye-3-tower kunye ne-five-tower process.Inkqubo ye-five-tower pressure swing adsorption method yeyona ndlela isetyenziswa ngokuqhelekileyo, esebenzisa iibhedi ezi-5 ze-adsorption, ii-blower ezi-4 kunye neepompo ze-vacuum ezi-2 ukugcina iibhedi ezi-2 kwi-adsorption kunye ne-vacuum ngexesha lonke lomjikelo, osombulula ingxaki yezobuchwepheshe ye-oksijini enkulu. imveliso.

Inkqubo yokuvelisa i-oksijini yoxinzelelo lwe-adsorption inezi nzuzo zilandelayo: Okokuqala, ithatha itekhnoloji yokutshaja ngokuzenzekelayo yomahluko woxinzelelo lomoya wokungenisa umoya ukunciphisa umthamo womoya we-oxygen, ukwandisa ubomi benkonzo yesixhobo, kunye nokunciphisa iindleko zokwenza ioksijini.Okwesibini zixhobo ezilula, izixhobo eziphambili I-Roots blower kunye nepompo ye-vacuum izinzile kwaye inokwethenjelwa, kwaye ubomi benkonzo ye-molecular sieve ingaphezu kweminyaka eyi-10 ngaphandle kokugcinwa.Okwesithathu kukuba inani kunye nokucoceka kwe-oksijini eveliswayo kunokulungiswa ngokuhambelana nokusetyenziswa kwangempela.Ukucoceka okuzinzileyo kunokufikelela kwi-93%, kwaye ukucoceka kwezoqoqosho ngu-80% ~ 90%;ixesha lokuvelisa i-oksijeni likhawuleza, kwaye ukucoceka kunokufikelela kwi-80% okanye ngaphezulu kwimizuzu engama-30;iyunithi Ukusetyenziswa kwamandla yi-0.32kWh/Nm3～0.37kWh/Nm3 kuphela.Okwesine, ukuthelekiswa kwe-pressure swing adsorption ukuveliswa kwe-oksijini kunye nemveliso ye-oksijini ye-cryogenic inezi mpawu zilandelayo: utyalo-mali oluphantsi, inkqubo elula, umsebenzi omncinci womhlaba, izixhobo ezincinci, kunye neendawo ezincinci ezihambayo;iqondo eliphezulu lokuzisebenzela, ulawulo olungenamntu lunokuphunyezwa;inokuhlangabezana neemfuno zenkqubo yokuqhushumba kwesithando somlilo seOxygen.
