Le teknoloji isetyenziswa kakhulu kumashishini ahlukeneyo afana ne-metallurgy, ubunjineli beekhemikhali, kunye namayeza. Eli nqaku liza kuhlola nzulu indlela ukwahlulwa komoya we-cryogenic okuvelisa ngayo i-nitrogen kunye ne-oxygen ecocekileyo kakhulu, kunye namanyathelo aphambili kunye nezixhobo ezibandakanyekayo kule nkqubo.

1. Umgaqo osisiseko wokwahlulwa komoya okrwada

Ukwahlulwa komoya okrwada yinkqubo eyahlula izinto eziphambili zomoya ngokunciphisa ubushushu. Umoya ikakhulu uqulathe initrogen, ioksijini, kunye nenani elincinci le-argon. Ngokucinezela nokupholisa umoya ukuya kubushushu obuphantsi kakhulu, umoya uyanyibilika, emva koko iindawo ezahlukeneyo zokubila zegesi nganye zisetyenziselwa ukunyibilikisa ukuze zahlule initrogen neoksijini. Indawo yokubila yenitrogen yi--195.8℃, kwaye eyeoksijini yi--183℃, ngoko ke zinokucocwa ngokwahlukeneyo ngokusebenzisa ukunyibilikisa ngokwezigaba.

2. Inqanaba langaphambi konyango: Ukucocwa komoya

Kwinkqubo yokwahlulwa komoya okrwada, unyango lwangaphambi komoya linyathelo lokuqala elibalulekileyo. Umoya uqulethe ukungcola okufana nothuli, i-carbon dioxide, kunye nokufuma, okuya kubanda kwindawo enobushushu obuphantsi, okubangela ukuvaleka kwezixhobo. Ke ngoko, umoya uqala ngokuhluzwa, ukucinezelwa, kunye namanyathelo okomisa ukuze kususwe ukungcola kunye nokufuma. Ngokwesiqhelo, izomisi kunye nee-molecular sieve adsorbers zizixhobo ezibalulekileyo ezisetyenziselwa ukususa ukungcola emoyeni, ukuqinisekisa uzinzo kunye nokusebenza kakuhle kwenkqubo yokwahlulwa kwe-cryogenic elandelayo.

3. Uxinzelelo lomoya kunye nokupholisa

Umoya ocociweyo kufuneka ucinezelwe, ngesiqhelo ngee-compressor ezininzi ukuze kunyuswe uxinzelelo lomoya ukuya kwi-5-6 megapascals. Umoya ocinezelweyo emva koko upholiswa ngee-heat exchangers kunye negesi ebuyayo kubushushu obuphantsi, oku kunciphisa kancinci ubushushu ukuze kufikelele kwindawo yokunyibilika. Kule nkqubo, ii-heat exchangers zidlala indima ebalulekileyo, njengoko zinokunciphisa ukusetyenziswa kwamandla ngempumelelo kwaye ziphucule ukusebenza kakuhle kokupholisa, ziqinisekisa ukuba umoya unokunyibilika phantsi kweemeko zobushushu obuphantsi, nto leyo ebonelela ngeemeko zokwahlulwa kwe-distillation elandelayo.

4. Ukunyibilikisa umoya kunye nokunyibilikisa

Kwinqaba yokwahlukanisa i-cryogenic, umoya oxinzelelweyo nopholileyo upholiswa ngakumbi ukuya kwimeko yokuba manzi. Umoya omanzi uthunyelwa kwinqaba yokwahlulahlula. Inqaba yokwahlulahlula ...

5. Inkqubo yokucoca

Ioksijini kunye ne-nitrogen ezahlulwe kwinqaba yokunyibilikisa zisenazo izinto ezincinci ezingcolisayo, ngoko ke kufuneka zicocwe ngakumbi ukuze zihlangabezane nemigangatho yemizi-mveliso neyezonyango. Ubunyulu be-nitrogen bunokuphuculwa ngokusebenzisa ii-catalysts ze-hydrogen deoxygenation, ngelixa ubunyulu be-oxygen bunokufezekiswa ngeenkqubo zokunyibilikisa kwakhona. Ukuphucula ubunyulu begesi yemveliso, izixhobo ezifana nezicoci ze-nitrogen kunye nezicoci ze-oxygen zihlala zisetyenziswa, ekugqibeleni zifumana iimveliso ze-oxygen kunye ne-nitrogen ezicocekileyo kakhulu.

6. Ukusetyenziswa kwenitrogen kunye neoksijini

I-nitrogen ecocekileyo kakhulu kunye neoksijini eveliswa yitekhnoloji yokwahlukanisa umoya we-cryogenic zisetyenziswa kakhulu kumashishini amaninzi. I-nitrogen ecocekileyo kakhulu isetyenziswa kumashishini eekhemikhali njengegesi ekhuselayo kunye negesi yokuthwala, kumashishini okutya ukugcinwa kunye nokupakishwa, kwaye ioksijini isetyenziswa kakhulu kumashishini ezonyango kunye nokudityaniswa kwentsimbi. Kumashishini esinyithi, ioksijini ikwasetyenziswa ukuphucula ukusebenza kakuhle kokutsha kunye nokunciphisa ukukhutshwa kwekhabhoni. Kwezi zicelo, ubunyulu begesi ngundoqo ekumiseleni ukusebenza kwayo, kwaye itekhnoloji yokwahlukanisa umoya we-cryogenic ifumene udumo olubanzi ngokwahlula kwayo okusebenzayo kunye nokukhupha kwayo ubunyulu obuphezulu.

7. Iingenelo kunye nemingeni yetekhnoloji yokwahlula umoya nge-cryogenic

Itekhnoloji yokwahlula umoya we-cryogenic iyathandwa kwicandelo lezemizi-mveliso ngenxa yobunyulu bayo obuphezulu kunye nokusebenza kakuhle. Nangona kunjalo, le teknoloji ikwajongene nemingeni ethile, njengokusetyenziswa kwamandla aphezulu kunye neendleko eziphezulu zokugcinwa kwezixhobo. Ukunciphisa ukusetyenziswa kwamandla, izixhobo zanamhlanje zokwahlula umoya we-cryogenic zihlala ziza neenkqubo eziphucukileyo zokonga amandla, ezifana nezixhobo zokubuyisa ubushushu kunye neenkqubo zokupholisa ezinamanqanaba amaninzi. Ngaphezu koko, ukusetyenziswa kwetekhnoloji yokulawula okuzenzakalelayo kuye kwaphucula kakhulu ukusebenza kakuhle kunye nokhuseleko lweeyunithi zokwahlula umoya we-cryogenic. Ngokusebenzisa ubuchwepheshe obuhle kunye nokuphuculwa kwezixhobo, ukusebenza kakuhle kwamandla kunye nokuzinza kweenkqubo zokwahlula umoya we-cryogenic ezinzulu kuye kwaphuculwa rhoqo, nto leyo ekhuthaza ukusetyenziswa kwazo kumashishini ahlukeneyo.
