Iprofayile yekhampani
Iyunithi yenitrogen engamanzi ephuhliswe yiyunithi yethu ithatha iPressure Swing Adsorption (PSA) ukulungiselela initrogen esulungekileyo, ethi ke ixutywe yi-mix-gas joule-thomson Refrigeration Cycle, MRC ngokufutshane) ukuvelisa initrogen engamanzi efunekayo.
Imigaqo yokuSebenza
Ngokubhekiselele kwifriji eboniswe kwi-Figure 1, inkqubo yayo yokusebenza yile: ifriji ephantsi yoxinzelelo lwe-fluid kwiqondo lokushisa eliphakathi T0 (ehambelana ne-state point 1s) ixinzelelwe kwi-high-pressure high-temperature gas (indawo ye-2) yi-compressor, kwaye emva koko ingene kwindawo epholileyo, njl njl. Ipholile phantsi kwiqondo lokushisa elisezantsi (inqaku lesi-3), ingena kwi-regenerative exchanger ubushushu, iphinda ipholiswe yi-reflux ephantsi-loxinzelelo lwegesi ephantsi lobushushu ukuya kwindawo ye-4, ingena kwi-valve ye-throttle, i-adiabatic throttling ukuya kwinqanaba. I-5, iqondo lokushisa liyehla, kwaye lingene kwi-evaporator ukubonelela ngokubanda Xa ubushushu buphakama ukuya kwindawo ye-6, ingena kwi-low-pressure passage ye-regenerative heat exchanger, kwaye ngelixa ipholisa ukuhamba okuphezulu koxinzelelo olungenayo, ubushushu bayo bubuyela ngokuthe ngcembe kwindawo. 1, kwaye emva koko ingena kumbhobho odibanisa umtshintshi wobushushu kunye ne-compressor. Kusenokubakho inxalenye yenkqubo ngeli xesha Ukuvuza kokushisa, ukushisa kuphakama kwiqondo lokushisa eliphantsi, libuyela kwindawo yesimo se-1 yesibini, kwaye inkqubo igqiba umjikelo. Inkqubo yefriji iyancipha ngokuthe ngcembe iqondo lokushisa ngokwenkqubo engentla, kwaye ekugqibeleni inikezela amandla efriji kwiqondo lokushisa elimiselweyo le-Tc. Ukupholisa umthwalo wokushisa osasazwayo, umthamo wokupholisa unikezelwa ngokuthe ngcembe ngexesha lenkqubo ye-reflux, njenge-liquefaction yegesi yendalo, njl.
Iimpawu zefriji edibeneyo edibeneyo yefriji
1) Ukuqalisa ngokukhawuleza kunye nesantya sokupholisa ngokukhawuleza. Ngokusebenzisa umlinganiselo oxutyiweyo wefriji, ukulungiswa komthamo wecompressor kunye nolawulo lokuvula ivalve ye-throttle, iimfuno zokupholisa ngokukhawuleza zinokufezekiswa;
2) Inkqubo ilula, inani lezixhobo lincinci, kwaye ukuthembeka kwenkqubo kuphezulu. Amacandelo aphambili enkqubo amkela i-compressor ekhulile, i-heater exchangers kunye nezinye izixhobo kwintsimi yefriji. Inkqubo inokuthembeka okuphezulu kunye noluhlu olubanzi lwemithombo yezixhobo.
Ixabiso lophuhliso lweyunithi yolwelo lwenitrogen oluxubene nefriji ikakhulu lubandakanya iinxalenye ezimbini: iyunithi yejenereyitha ye-nitrogen ye-PSA kunye neyunithi yokunyibilikisa kwe-MRC. I-PSA nitrogen generator ikhulile kwaye kulula ukuyithenga kwimarike yasekhaya.
