Iphrofayela Yenkampani
Iyunithi ye-nitrogen ewuketshezi ethuthukiswe iyunithi yethu isebenzisa i-Pressure Swing Adsorption (PSA) ukuze ilungise i-nitrogen ehlanzekile, ebese iphonswa i-mix-gas joule-thomson Refrigeration Cycle, i-MRC okwesikhashana) ukuze ikhiqize i-nitrogen ewuketshezi edingekayo.
Izimiso Zokusebenza
Ibhekisela esiqandisini esiboniswe kuMfanekiso 1, inqubo yaso yokusebenza yilena: isiqandisi esiwuketshezi olunomfutho ophansi ezingeni lokushisa elizungezile i-T0 (elihambisana nephoyinti lesifunda 1s) licindezelwa libe yigesi yokushisa okuphezulu komfutho ophezulu (iphuzu lesifunda 2) yi-compressor, futhi bese ingena endaweni epholile, njll. Ipholile phansi kumazinga okushisa azungezile (iphuzu lesi-3), ingena emshinini wokushisa ovuselelayo, iphinde ipholiswe igesi ye-reflux low-pressure low-temperature ukuze ibeke iphuzu 4, ingena ku-throttle valve, i-adiabatic throttling ukuze ikhombe. I-5, izinga lokushisa liyehla, futhi lingene ku-evaporator ukuze linikeze amakhaza Lapho izinga lokushisa likhuphuka lifika ku-6, lingena endaweni yokucindezela okuphansi kwesishintshi sokushisa esivuselelayo, futhi ngenkathi kupholisa ukugeleza okungenayo kokucindezela okuphezulu, izinga lokushisa layo kancane kancane libuyela endaweni. 1, bese ingena epayipini elixhuma isishintshi sokushisa kanye ne-compressor. Kungase kube nengxenye yesistimu ngalesi sikhathi Ukuvuza kokushisa, izinga lokushisa likhuphukela kuzinga lokushisa elizungezile, libuyela endaweni yesimo isekhondi elingu-1, futhi uhlelo luqeda umjikelezo. Uhlelo lwesiqandisi kancane kancane lunciphisa izinga lokushisa ngokusho kwenqubo engenhla, futhi ekugcineni lunikeze amandla okuqandisa ekushiseni kwefriji okumisiwe Tc. Ngokupholisa komthwalo wezinga lokushisa okusabalalisa, umthamo wokupholisa unikezwa kancane kancane ngesikhathi senqubo ye-reflux, njenge-liquefaction yegesi yemvelo, njll.
Izici zesiqandisi esixutshwe nesiqandisi esiphunduzayo
1) Ukuqalisa okusheshayo nezinga lokupholisa ngokushesha. Ngokusebenzisa isilinganiso sokuhlushwa kwesiqandisi esixubile, ukulungiswa kwamandla we-compressor kanye nokulawula ukuvulwa kwe-throttle valve, izidingo zokupholisa ngokushesha zingafinyelelwa;
I-2) Inqubo ilula, inani lemishini lincane, futhi ukwethembeka kwesistimu kuphezulu. Izingxenye eziyinhloko zesistimu zisebenzisa ama-compressor avuthiwe, ama-heaters nezinye izinto zokusebenza endaweni yesiqandisi. Uhlelo linokwethenjelwa okuphezulu kanye nohlu olubanzi lwemithombo yemishini.
Izindleko zokuthuthukiswa kweyunithi ye-nitrogen ewuketshezi eyisiqandisi exubile ikakhulukazi ihlanganisa izingxenye ezimbili: Iyunithi yejeneretha ye-nitrogen ye-PSA kanye neyunithi ye-MRC ye-liquefaction. Ijeneretha ye-nitrogen ye-PSA isivuthiwe futhi kulula ukuyithenga emakethe yasekhaya.
