Umshini osebenzisa izindlela ezingokoqobo ukuze uhlukanise umoya-mpilo emoyeni ukuze uthole i-nitrogen ubizwa ngokuthi ijeneretha ye-nitrogen.Kunezinhlobo ezintathu eziyinhloko zamajeneretha e-nitrogen, okuyi-cryogenic air separation, molecular sieve air separation (PSA) kanye noMthetho wokuhlukanisa umoya we-membrane.Namuhla, umkhiqizi wamajeneretha e-nitrogen-HangZhou Sihope technology co.,ltd.izokhuluma kafushane mayelana nesimiso kanye nezinzuzo ze-pressure swing adsorption oxygen generation.
indlela ye-press swing adsorption, okungukuthi indlela ye-PSA, iwukukhangisa ngengcindezi ephezulu ukuze kuzuzwe ukuhlukaniswa kwegesi, kanye nokuzuza ukuvuselelwa kwe-adsorbent ngengcindezi ephansi.Le ndlela isekelwe ekukhetheni isisefo se-molecule yezingxenye ze-oxygen ne-nitrogen emoyeni ukuze zihlukanise umoya ukuze kutholwe umoya-mpilo.Lapho umoya ucindezelwa futhi udlula embhoshongweni we-adsorption ofakwe izisefo zamangqamuzana, ama-molecule e-nitrogen athandwa kakhulu, futhi ama-molecule e-oksijini ahlala esigabeni segesi futhi abe umoya-mpilo.Lapho i-adsorption ifinyelela ekulinganeni, ama-molecule e-nitrogen akhangisiwe ebusweni besisefo samangqamuzana akhishwa ngokuncishiswa kwengcindezi noma i-vacuum, futhi amandla okukhangisa esisefo samangqamuzana ayabuyiselwa.Ukuze unikeze ngokuqhubekayo umoya-mpilo, idivayisi ivamise ukuba nemibhoshongo ye-adsorption emibili noma ngaphezulu, umbhoshongo owodwa ukhangisa umoya-mpilo kanye nomunye ama-desorbs ombhoshongo, ukuze kufezwe inhloso yokukhiqiza umoya-mpilo okuqhubekayo.
Indlela ye-PSA ingakhiqiza umoya-mpilo ngokuhlanzeka okungama-80% -95%.Amandla asetshenziswa ekukhiqizeni umoya-mpilo ngokuvamile ngu-0.32kWh/Nm3～0.37kWh/Nm3, futhi ingcindezi ye-adsorption iphezulu kunomfutho womkhathi, ngokuvamile ongu-30kPa～100kPa.Inqubo ilula, ukusebenza ekamelweni lokushisa, kanye nezinga le-automation High, lingakwazi ukubona ukuphathwa okungenamuntu, ikakhulukazi ukuphepha okuhle.Enqubweni ye-vacuum desorption, ingcindezi yokusebenza yedivayisi iphansi, futhi isiqukathi asilawulwa ukucaciswa kwesiqukathi sokucindezela.Ngokuya ngenani lama-adsorbers, inqubo ye-press swing adsorption ihlukaniswe yaba inqubo yombhoshongo owodwa, inqubo enemibhoshongo emibili, inqubo enemibhoshongo emithathu, kanye nenqubo yemibhoshongo emihlanu.Inqubo ye-five-tower pressure swing adsorption method iyona esetshenziswa kakhulu, esebenzisa imibhede engu-5 yokukhangisa, ama-blower angu-4 namaphampu e-vacuum angu-2 ukuze kugcinwe imibhede engu-2 endaweni yokukhangisa kanye ne-vacuum phakathi nawo wonke umjikelezo, okuxazulula inkinga yobuchwepheshe yomoya-mpilo omkhulu. ukukhiqizwa.
Inqubo yokukhiqiza i-pressure swing adsorption oxygen inalezi zinzuzo ezilandelayo: Okokuqala, isebenzisa ubuchwepheshe bokushaja obuzenzakalelayo bomehluko we-atmospheric inlet pressure ukuze kuncishiswe umthamo womoya wesiphephetha-moya, kwelule impilo yesevisi yezinto zokusebenza, nokunciphisa izindleko zokukhiqiza umoya-mpilo.Okwesibili yimishini elula, imishini eyinhloko I-Roots blower kanye nepompo ye-vacuum izinzile futhi inokwethenjelwa, futhi impilo yesevisi ye-sieve yamangqamuzana ingaphezu kweminyaka eyi-10 ngaphandle kokugcinwa.Okwesithathu ukuthi inani nokuhlanzeka kwe-oksijini ekhiqizwayo kungalungiswa ngokuvumelana nokusetshenziswa kwangempela.Ukuhlanzeka okuzinzile kungafinyelela ku-93%, futhi ukuhlanzeka kwezomnotho kungu-80% ~ 90%;isikhathi sokukhiqiza i-oxygen siyashesha, futhi ubumsulwa bungafinyelela ku-80% noma ngaphezulu phakathi nemizuzu engu-30;Iyunithi Ukusetshenziswa kwamandla kungu-0.32kWh/Nm3～0.37kWh/Nm3 kuphela.Okwesine, ukuqhathaniswa kwe-pressure swing adsorption ukukhiqizwa kwe-oksijeni kanye nokukhiqizwa kwe-oksijini ye-cryogenic kunezici ezilandelayo: ukutshalwa kwezimali okuphansi, inqubo elula, indawo encane yokuhlala, imishini encane, nezingxenye ezimbalwa ezihambayo;izinga eliphezulu lokuzenzakalela, ngokuyisisekelo ukuphathwa okungenamuntu kungenziwa;ingahlangabezana nezidingo zenqubo yenqubo yokuqhuma kwe-Oxygen ecebile yesithando somlilo.
