Izinhlobo zokukhiqiza i-nitrogen zihlanganisa i-press swing adsorption, ukuhlukaniswa kwe-membrane kanye nokuhlukaniswa komoya we-cryogenic.Ijeneretha ye-nitrogen iyisisetshenziswa se-nitrogen esakhiwe futhi sakhiwe ngokuya ngobuchwepheshe be-press swing adsorption.Umshini we-nitrogen usebenzisa isisefo se-carbon molecular molecular sekhwalithi ephezulu njenge-adsorbent futhi usebenzisa isimiso sokushintshashintsha kwezinga lokushisa kwegumbi ukuze kuhlukanise umoya ukuze kukhiqizwe i-nitrogen ephezulu.Imvamisa, imibhoshongo emibili yokukhangisa ixhunywe ngokuhambisana, futhi i-PLC engenisiwe ilawula ukusebenza okuzenzakalelayo kwevalvu yomoya ephuma kwamanye amazwe ukuze ikhiphe ukukhangisa okucindezelwe kanye nokuvuselelwa kabusha kokucindezela ukuze kuqedelwe ukuhlukaniswa kwe-nitrogen nomoya-mpilo futhi ithole i-nitrogen ephezulu edingekayo.
Indlela yokuqala ukukhiqizwa kwe-nitrogen ngenqubo ye-cryogenic
Le ndlela iqala ngokucindezela futhi ipholise umoya, bese iwuncibilikisa umoya.Kusetshenziswa amaphuzu ahlukene abilayo ezingxenye ze-oksijini ne-nitrogen, ukuthintana kwegesi noketshezi ethreyini yekholomu yokucwiliswa kwe-distillation ngokushintshana kobukhulu nokushisa.I-oksijini enephuzu lokubilisa eliphakeme ngokuqhubekayo ijiya isuka kusitimu ibe uketshezi, futhi i-nitrogen enephuzu eliphansi lokubilisa iqhubeka idluliswa kusitimu, ukuze okuqukethwe kwe-nitrogen esitiyeni esikhuphukayo kuqhubeke kwanda, kuyilapho okuqukethwe komoyampilo ngaphansi komfula. uketshezi luphakeme futhi luphakeme.Ngakho-ke, umoya-mpilo ne-nitrogen kuyahlukaniswa ukuze kutholakale i-nitrogen noma umoya-mpilo.Le ndlela yenziwa ekushiseni okungaphansi kuka-120K, ngakho-ke kubizwa ngokuthi ukuhlukaniswa komoya we-cryogenic.
Okwesibili ukusebenzisa i-press swing adsorption ukukhiqiza i-nitrogen
Indlela ye-pressure swing adsorption iwukukhetha ngokukhetha izingxenye ze-oxygen ne-nitrogen emoyeni ngokusebenzisa i-adsorbent, futhi uhlukanise umoya ukuze uthole i-nitrogen.Lapho umoya ucindezelwa futhi udlula ungqimba lwe-adsorption lombhoshongo we-adsorption, ama-molecule e-oksijini athandwa kakhulu, futhi ama-molecule e-nitrogen asala esigabeni segesi ukuze abe i-nitrogen.Lapho i-adsorption ifinyelela ekulinganeni, ama-molecule e-oksijini akhangisiwe ebusweni besisefo samangqamuzana akhishwa ngokucindezelwa ukuze kubuyiselwe amandla okukhangisa esisefo samangqamuzana, okungukuthi, ukuhlaziywa kwe-adsorbent.Ukuze unikeze i-nitrogen ngokuqhubekayo, iyunithi ivamise ukuhlonyiswa ngemibhoshongo emibili noma ngaphezulu ye-adsorption, eyodwa nge-adsorption kanye neyokuhlaziya, futhi ishintshelwa ukusetshenziswa ngesikhathi esifanele.
Indlela yesithathu ukukhiqiza i-nitrogen ngokuhlukanisa ulwelwesi
Indlela yokuhlukanisa i-Membrane iwukuhlukanisa igesi ecebile ene-nitrogen kwigesi exubile ngokusebenzisa ukukhetha kokufinyeleleka kwe-organic polymerization membrane.Izinto zefilimu ezifanele kufanele zibe nokukhetha okuphezulu kanye nokungena okuphezulu.Ukuze uthole inqubo yokonga, i-membrane encane kakhulu yokuhlukanisa i-polymer iyadingeka, ngakho idinga ukusekelwa.Ama-projectile abhoboza izikhali ngokuvamile ama-projectiles ahlabayo ezikhali eziyisicaba kanye nama-projectiles abhoboza i-armor angenalutho.Kule ndlela, uma ukukhiqizwa kwegesi kukukhulu, indawo yefilimu edingekayo inkulu kakhulu futhi intengo yefilimu iphezulu.Indlela yokuhlukanisa i-Membrane inomshini olula nokusebenza okulula, kodwa ayisetshenziswa kakhulu embonini.
Ukufingqa, lokhu okungenhla kungukuqukethwe okuyinhloko kwezindlela ezimbalwa zokukhiqiza i-nitrogen.Ukuhlukaniswa komoya we-Cryogenic akukwazi ukukhiqiza kuphela i-nitrogen, kodwa futhi ne-nitrogen ewuketshezi, engagcinwa ethangini lokugcina i-nitrogen ewuketshezi.Umjikelezo wokusebenza wokukhiqizwa kwe-nitrogen ye-cryogenic ngokuvamile ungaphezu konyaka owodwa, ngakho okokusebenza okulindile ngokuvamile akucatshangelwa ukukhiqizwa kwe-nitrogen ye-cryogenic.Umgomo wokukhiqizwa kwe-nitrogen ngokuhlukaniswa komoya we-membrane ukuthi umoya ungena kusihlungi se-polymer membrane ngemva kokuhlungwa yi-compressor.Ngenxa yokuncibilika okuhlukile kanye ne-coefficient yokusabalalisa yamagesi ahlukene kulwelwesi, izinga lokungena elihlobene kulwelwesi lwegesi oluhlukile lihlukile.Uma ubumsulwa be-nitrogen bungaphezu kwama-98%, intengo ingaphezulu kuka-15% ngaphezu kwaleyo ye-PSA nitrogen generator yencazelo efanayo.
