Isingeniso

Uketshezi oluyi-cryogenic njenge-nitrogen ewuketshezi (LN₂), i-oxygen ewuketshezi (LOX), i-argon ewuketshezi (LAr), igesi yemvelo ewuketshezi (LNG), kanye ne-hydrogen ewuketshezi (LH₂) zidlala indima ebalulekile ezimbonini ezisukela ekukhiqizweni kwegesi yezimboni kanye ne-biotechnology kuya ekukhiqizweni kwe-semiconductor, i-aerospace, kanye namandla ahlanzekile.

Inselele eyodwa evamile kuzo zonke lezi zinhlelo zokusebenza ukugcina amazinga okushisa aphansi kakhulu ngesikhathi sokudluliselwa. Ngaphandle kokushisa okwanele, ukushisa okuvela endaweni ezungezile kungena ngokushesha ohlelweni, okubangela ukulahlekelwa komkhiqizo ngokushiswa komoya kanye nokunciphisa ukusebenza kahle kwenqubo iyonke.

Ukuze kuxazululwe le nselele, izikhungo eziningi zesimanje ze-cryogenic zithembele kumapayipi avikelayo nge-vacuum (VIPs), aziwa nangokuthi amapayipi avikelayo nge-vacuum. Lezi zinhlelo zenzelwe ngqo ukunciphisa ukungena kokushisa nokuqinisekisa ukudluliselwa okusebenzayo nokuthembekile koketshezi lwe-cryogenic.

Kungani Ukudluliselwa Koketshezi Okuyi-Cryogenic Kudinga Amapayipi Akhethekile

Uketshezi oluyi-cryogenic lugcinwa emazingeni okushisa angaphansi kakhulu kwezimo ezizungezile:

Ngenxa yokuthi umehluko wokushisa phakathi koketshezi nendawo ezungezile uvame ukudlula ama-200°C, ukushisa ngokwemvelo kugeleza ohlelweni lokudlulisa. Ngisho nokungena okuncane kokushisa kungabangela ukuthi ingxenye yoketshezi iphenduke umhwamuko.

Lokhu kungaholela ku:

• Ukwanda kwegesi yokubilisa (BOG)
• Ukulahlekelwa komkhiqizo
• Ukushintshashintsha kwengcindezi
• Izimo zokugeleza kwezigaba ezimbili
• Ukunciphisa ukusebenza kahle kwenqubo
• Izindleko zokusebenza eziphakeme

Ukuze kusetshenziswe izinhlelo zokusebenza ezidinga ukulethwa koketshezi okuzinzile, ukuvikela ukushisa okusebenzayo kubalulekile.

Indlela Amapayipi Afakwe I-Vacuum Asebenza Ngayo

Ipayipi elivalekile elifakwe i-vacuum liqukethe amapayipi amabili ensimbi engagqwali aqinile.

Ipayipi elingaphakathi lithwala uketshezi oluyi-cryogenic, kuyilapho ipayipi elingaphandle lakha ijazi elivikelayo. Phakathi kwamapayipi amabili kukhona isikhala esiphezulu se-vacuum esisebenza njengesivikelo sokushisa esisebenzayo.

Izinhlelo eziningi zokusebenza kahle kakhulu nazo zifaka phakathi i-multilayer insulation (MLI) ngaphakathi kwesikhala se-vacuum. Ndawonye, ​​i-vacuum kanye ne-MLI kunciphisa kakhulu zonke izinhlobo zokudluliselwa kokushisa, okuhlanganisa ukuhanjiswa, ukuhanjiswa kwe-convection, kanye nemisebe.

Uma kuqhathaniswa namapayipi avamile afakwe i-foam, amapayipi afakwe i-vacuum anciphisa kakhulu ukuvuza kokushisa, okusiza ukugcina uketshezi olucryogenic lusesimweni esizinzile kulo lonke uhambo.

Ukuhamba kwe-LNG kusetshenziswa amapayipi afakwe i-vacuum insulation

Igesi Yemvelo Encibilikisiwe (i-LNG) ivame ukugcinwa futhi ithuthwe cishe ku--162°C. Ukugcina leli zinga lokushisa kubalulekile ekunciphiseni ukukhiqizwa kwegesi ebilayo nokuqinisekisa ukusebenza kahle.

Ezikhungweni ze-LNG, amapayipi afakwe i-vacuum insulation avame ukusetshenziswa ku:

• Ukuxhumeka kwethangi lokugcina izinto
• Izinhlelo zokulayisha amaloli
• Izindawo zokuhlala emanzini angaphansi komhlaba
• Ama-skid okudlulisa i-LNG
• Amatheminali okuvuselela igesi

Ngokunciphisa ukungena kokushisa, amapayipi afakwe i-vacuum tincture asiza ukugcina i-LNG isesimweni sayo soketshezi ngesikhathi sokulayisha, ukulayisha, kanye nokusabalalisa izinqubo. Amazinga aphansi okwehla kwesisindo nawo anegalelo ekuthuthukiseni ukusebenza kahle kanye nokunciphisa ukulahlekelwa komkhiqizo.

Izicelo Zokudlulisa I-Hydrogen Ewuketshezi

I-hydrogen ewuketshezi ingenye yezinhlobo zoketshezi eziyinselele kakhulu ukubhekana nazo ngenxa yokuthi iphansi kakhulu lapho ibila khona cishe ngo-253°C.

Izicelo zifaka:

• Izitshalo zokuphuza i-hydrogen
• Izikhungo zokuqalisa izindiza
• Iziteshi zikaphethiloli ze-hydrogen
• Amalebhu ocwaningo
• Amaphrojekthi engqalasizinda ye-hydrogen eluhlaza

Ngenxa yokuthi ama-molecule e-hydrogen mancane kakhulu futhi ahamba kakhulu, ukugcina ukusebenza kokuvikela kubaluleke kakhulu. Amapayipi avikela ugesi asiza ekunciphiseni ukuvuza kokushisa futhi anciphise ukuhwamuka, okwenza abe yisisombululo esithandwayo sezinhlelo zokudlulisa i-hydrogen ewuketshezi.

Imiklamo ethuthukisiwe ivame ukufaka ukufakelwa kwezingqimba eziningi, izakhiwo zokusekela ezikhethekile, kanye namazinga e-vacuum alawulwa ngokucophelela ukuze kufezwe ukusebenza kokushisa okudingekayo.

Izicelo Zokudlulisa I-Nitrogen Ewuketshezi

I-nitrogen ewuketshezi isetshenziswa kabanzi ezimbonini eziningi, okuhlanganisa:

• Ukukhiqizwa kwe-semiconductor
• I-Biotechnology kanye nesayensi yokuphila
• Ukukhiqizwa kwemithi
• Ukucubungula nokugcina ukudla kuqandisiwe
• Ukusatshalaliswa kwegesi yezimboni

Kulezi zikhungo, amapayipi afakwe i-vacuum vulnerable athutha i-LN₂ esuka emathangini okugcina izinto eziningi aye ezindaweni zemishini nezinqubo kulo lonke isitshalo.

Ukusetshenziswa kwezinhlelo ze-VIP kusiza:

• Gcina ukulethwa koketshezi okuzinzile
• Nciphisa ukusetshenziswa kwe-nitrogen
• Thuthukisa ukuhambisana kwenqubo
• Izindleko zokusebenza eziphansi
• Nciphisa izidingo zokwakheka kweqhwa kanye nokugcinwa kwalo

Ezindaweni ezinkulu ze-semiconductor, amapayipi afakwe i-vacuum avame ukunwebeka amakhulu amamitha ukuqinisekisa ukutholakala okuqhubekayo kwe-nitrogen ewuketshezi ehlanzekile kakhulu.

Izingxenye zeSistimu Yokudlulisa Ephelele Ye-Cryogenic

Inethiwekhi yokudlulisa i-cryogenic ihilela okungaphezu nje kokufaka amapayipi afakwe umswakama. Kuye ngohlelo lokusebenza, uhlelo lungafaka futhi:

• Amavalvu okushisa angenawo umoya
• Amapayipi aguquguqukayo agqunywe nge-vacuum
• Abahlukanisi besigaba
• Imishini yokulawula ukucindezela
• Amalunga okunwebeka
• Amadivayisi okuqapha i-vacuum
• Izinhlelo zokulungisa i-vacuum ezinamandla

Lezi zingxenye zisebenza ndawonye ukuqinisekisa ukusebenza kahle, izimo zokugeleza ezizinzile, kanye nokuthembeka kwesikhathi eside.

Izinzuzo Zamapayipi Afakwe Umshini Wokufudumeza

Amapayipi afakwe ugesi asebe yisisombululo esithandwayo sokudlulisa uketshezi oluyi-cryogenic ngoba anikeza izinzuzo eziningana ezibalulekile:

Ukuvuza Kokushisa Okuncishisiwe

Isikhala se-vacuum sinikeza ukuvikelwa okuhle kakhulu kokushisa, kunciphisa ukudluliselwa kokushisa kusuka endaweni ezungezile.

Ukulahlekelwa Komkhiqizo Okuphansi

Ukungena kokushisa okuncishisiwe kusho ukuhwamuka okuncane kanye namazinga aphansi okubila.

Ukuqina Kwenqubo Okuthuthukisiwe

Ukugcina uketshezi olune-cryogenic esimweni sesigaba esisodwa kusiza ukuqinisekisa izimo zokucindezela nokugeleza ezizinzile.

Ukwanda Kokusebenza Kahle Kwamandla

Ukulahlekelwa okuncane komkhiqizo kuveza izindleko zokusebenza eziphansi kanye nokusebenza kahle kohlelo okuthuthukisiwe.

Ukuthembeka Kwesikhathi Eside

Amapayipi afakwe i-vacuum tincture aklanywe kahle ahlinzeka ngokusebenza kahle kokushisa iminyaka eminingi yokusebenza.

Isiphetho

Ukuthuthwa okuphephile nokuphumelelayo koketshezi oluyi-cryogenic kuncike ekunciphiseni ukudluliselwa kokushisa kuyo yonke inqubo yokudlulisa. Kungakhathaliseki ukuthi kuphathwa i-LNG, i-nitrogen ewuketshezi, i-oxygen ewuketshezi, noma i-hydrogen ewuketshezi, ukugcina amazinga okushisa aphansi kubalulekile ekulondolozeni ikhwalithi yomkhiqizo kanye nokunciphisa ukulahleka kokusebenza.

Amapayipi afakwe i-vacuum cleaner aseyindinganiso embonini ngoba anikeza ukusebenza okuphezulu kokushisa, amazinga aphansi okubila, ukusebenza kahle okuthuthukisiwe, kanye nokusebenza okuthembekile kwesikhathi eside. Njengoba isidingo sezinhlelo zokusebenza ze-cryogenic siqhubeka nokukhula kuyo yonke imikhakha yamandla, igesi yezimboni, i-biotechnology, kanye ne-semiconductor, ubuchwepheshe bamapayipi afakwe i-vacuum cleaner buzohlala buyingxenye ebalulekile yengqalasizinda yesimanje ye-cryogenic.
