Uketshezi oluyi-cryogenic njenge-nitrogen ewuketshezi (LN2), i-hydrogen ewuketshezi (LH2), kanye negesi yemvelo ewuketshezi (LNG) kubalulekile ezimbonini ezahlukene, kusukela ekusetshenzisweni kwezokwelapha kuya ekukhiqizweni kwamandla. Ukuthuthwa kwalezi zinto ezinokushisa okuphansi kudinga izinhlelo ezikhethekile ukuze zigcine amazinga azo okushisa abandayo kakhulu futhi zivimbele ukuhwamuka. Enye yezindlela zobuchwepheshe eziphumelela kakhulu zokuthutha uketshezi oluyi-cryogenic yi- ipayipi elivalekile elifudumeleNgezansi, sizohlola ukuthi lezi zinhlelo zisebenza kanjani nokuthi kungani zibalulekile ekuthuthweni ngokuphephile koketshezi oluyi-cryogenic.

Inselele Yokuthutha Uketshezi Oluyi-Cryogenic

Uketshezi oluyi-cryogenic lugcinwa futhi luthuthwe emazingeni okushisa angaphansi kuka-150°C (-238°F). Emazingeni okushisa aphansi kangaka, luvame ukuhwamuka ngokushesha uma luvezwa ezimweni ezizungezile. Inselele enkulu ukunciphisa ukudluliselwa kokushisa ukuze kugcinwe lezi zinto zisesimweni sazo soketshezi ngesikhathi sokuthuthwa. Noma yikuphi ukwanda kwezinga lokushisa kungabangela ukuhwamuka okusheshayo, okuholela ekulahlekelweni komkhiqizo kanye nezingozi zokuphepha ezingaba khona.

Iphayiphi Elifakwe Umshini Wokufudumeza: Isihluthulelo Sokuthutha Okusebenzayo

Amapayipi afakwe ugesi(VIPs) ziyisisombululo esibalulekile sokuthutha uketshezi oluyi-cryogenic amabanga amade ngenkathi kunciphisa ukudluliselwa kokushisa. Lawa mapayipi aqukethe izendlalelo ezimbili: ipayipi langaphakathi, elithwala uketshezi oluyi-cryogenic, kanye nepayipi langaphandle elihlanganisa ipayipi langaphakathi. Phakathi kwalezi zendlalelo ezimbili kukhona i-vacuum, esebenza njengesithiyo sokuvimbela ukufudumala ukunciphisa ukuqhutshwa kokushisa kanye nemisebe.ipayipi elivalekile elifudumeleubuchwepheshe bunciphisa kakhulu ukulahlekelwa ukushisa, okuqinisekisa ukuthi uketshezi luhlala ekushiseni okudingekayo kulo lonke uhambo lwalo.

Isicelo kwezokuthutha ze-LNG

Igesi yemvelo encibilikisiwe (i-LNG) iwumthombo kaphethiloli odumile futhi kumele ithuthwe emazingeni okushisa aphansi njengo--162°C (-260°F).Amapayipi afakwe ugesizisetshenziswa kabanzi ezindaweni ze-LNG kanye nasezikhumulweni zemikhumbi ukuhambisa i-LNG kusuka emathangini okugcina impahla kuya emikhunjini noma kwezinye izitsha zokuthutha. Ukusetshenziswa kwama-VIP kuqinisekisa ukungena okuncane kokushisa, kunciphisa ukwakheka kwegesi elibilayo (i-BOG) kanye nokugcina i-LNG isesimweni sayo soketshezi ngesikhathi sokulayishwa nokukhishwa kwempahla.

Ukuthuthwa kwe-Hydrogen Ewuketshezi kanye ne-Nitrogen Ewuketshezi

Ngokufanayo,amapayipi afakwe ugesizibalulekile ekuthuthweni kwe-hydrogen ewuketshezi (LH2) kanye ne-nitrogen ewuketshezi (LN2). Isibonelo, i-hydrogen ewuketshezi ivame ukusetshenziswa ekuhloleni isikhala kanye nobuchwepheshe bamaseli kaphethiloli. Iphuzu layo lokubila eliphansi kakhulu elingu--253°C (-423°F) lidinga izinhlelo zokuthutha ezikhethekile. Ama-VIP ahlinzeka ngesisombululo esifanele, esivumela ukunyakaza okuphephile nokusebenza kahle kwe-LH2 ngaphandle kokulahlekelwa okukhulu ngenxa yokudluliselwa kokushisa. I-nitrogen ewuketshezi, esetshenziswa kabanzi kwezokwelapha nasezimbonini, nayo iyazuza kuma-VIP, iqinisekisa izinga lokushisa layo elizinzile kuyo yonke inqubo.

Isiphetho: Indima KaAmapayipi Afakwe Umshini Wokufudumeza Esikhathini Esizayo Se-Cryogenics

Njengoba izimboni ziqhubeka nokuthembela kuketshezi oluyi-cryogenic, amapayipi afakwe ugesiizodlala indima ebaluleke kakhulu ekuqinisekiseni ukuthi ukuthuthwa kwayo kuphephile futhi kusebenza kahle. Njengoba ikwazi ukunciphisa ukudluliselwa kokushisa, ukuvimbela ukulahleka komkhiqizo, nokuthuthukisa ukuphepha, ama-VIP ayisici esibalulekile emkhakheni okhulayo we-cryogenic. Kusukela ku-LNG kuya ku-hydrogen ewuketshezi, lobu buchwepheshe buqinisekisa ukuthi uketshezi olusezingeni eliphansi lokushisa lungathuthwa ngomthelela omncane kakhulu emvelweni kanye nokusebenza kahle okukhulu.
