Chiyambi

Zakumwa zoziziritsa kukhosi monga nayitrogeni yamadzimadzi (LN₂), mpweya wamadzimadzi (LOX), argon yamadzimadzi (LAr), mpweya wachilengedwe wosungunuka (LNG), ndi hydrogen yamadzimadzi (LH₂) zimakhala ndi gawo lofunika kwambiri m'mafakitale kuyambira kupanga gasi wa mafakitale ndi biotechnology mpaka kupanga ma semiconductor, ndege, ndi mphamvu zoyera.

Vuto limodzi lodziwika bwino pa ntchito zonsezi ndi kusunga kutentha kochepa kwambiri panthawi yosamutsa. Popanda kutenthetsa kokwanira, kutentha kuchokera ku malo ozungulira kumalowa mwachangu mu dongosolo, zomwe zimapangitsa kuti zinthu zitayike chifukwa cha nthunzi komanso kuchepetsa magwiridwe antchito onse.

Pofuna kuthana ndi vutoli, malo ambiri amakono osungira madzi a cryogenic amadalira mapaipi oteteza madzi a vacuum insulated (VIPs), omwe amadziwikanso kuti mapaipi oteteza madzi a vacuum. Machitidwewa adapangidwa makamaka kuti achepetse kutentha kulowa ndikuwonetsetsa kuti madzi a cryogenic akuyenda bwino komanso modalirika.

Chifukwa Chake Kutumiza Madzi a Cryogenic Kumafuna Mapaipi Apadera

Madzi a cryogenic amasungidwa kutentha kocheperako poyerekeza ndi momwe zinthu zilili:

Popeza kusiyana kwa kutentha pakati pa madzi ndi malo okhala nthawi zambiri kumapitirira 200°C, kutentha kumalowa mwachibadwa mu dongosolo losamutsira. Ngakhale kutentha pang'ono kungapangitse kuti madziwo asungunuke.

Izi zitha kubweretsa:

• Kuwonjezeka kwa mpweya woipa (BOG)
• Kutayika kwa zinthu
• Kusinthasintha kwa kuthamanga kwa magazi
• Mikhalidwe ya kayendedwe ka magawo awiri
• Kuchepetsa magwiridwe antchito
• Ndalama zogwirira ntchito zokwera

Pa ntchito zomwe zimafuna kuperekedwa kwa madzi mokhazikika, kutenthetsa bwino kutentha ndikofunikira.

Momwe Mapaipi Otetezedwa ndi Vacuum Amagwirira Ntchito

Chitoliro chotetezedwa ndi vacuum chimakhala ndi mapaipi awiri osapanga dzimbiri.

Chitoliro chamkati chimanyamula madzi oundana, pomwe chitoliro chakunja chimapanga jekete loteteza. Pakati pa mapaipi awiriwa pali malo otseguka okhala ndi vacuum yambiri omwe amagwira ntchito ngati chotchinga cha kutentha.

Makina ambiri ogwira ntchito bwino amaphatikizanso kutchinjiriza kwa multilayer (MLI) mkati mwa vacuum space. Pamodzi, vacuum ndi MLI zimachepetsa kwambiri mitundu yonse ya kutentha, kuphatikizapo conduction, convection, ndi radiation.

Poyerekeza ndi mapaipi opangidwa ndi thovu, mapaipi opangidwa ndi vacuum amachepetsa kwambiri kutentha komwe kumatuluka, zomwe zimathandiza kuti madzi a cryogenic akhale olimba panthawi yonse yoyendera.

Mayendedwe a LNG Pogwiritsa Ntchito Mapaipi Otetezedwa ndi Vacuum

Mpweya Wachilengedwe Wosungunuka (LNG) nthawi zambiri umasungidwa ndikunyamulidwa pa -162°C. Kusunga kutentha kumeneku ndikofunikira kwambiri pochepetsa kupanga mpweya wozizira komanso kuonetsetsa kuti ntchito ikuyenda bwino.

Mu malo opangira LNG, mapaipi oteteza mpweya woipa amagwiritsidwa ntchito kwambiri pa:

• Kulumikiza thanki yosungiramo zinthu
• Makina opakira katundu m'magalimoto
• Malo osungiramo zinthu za m'madzi
• Ma skid osamutsa LNG
• Malo osinthira magetsi

Mwa kuchepetsa kulowa kwa kutentha, mapaipi otetezedwa ndi vacuum amathandiza kusunga LNG mu mkhalidwe wake wamadzimadzi panthawi yokweza, kutsitsa, ndi kugawa. Kutsika kwa kuchuluka kwa madzi owiritsa kumathandizanso kuti ntchito iyende bwino komanso kuchepetsa kutayika kwa zinthu.

Kugwiritsa Ntchito Kusamutsa Hydrogen Yamadzimadzi

Madzi a haidrojeni ndi amodzi mwa madzi ovuta kwambiri kugwiritsa ntchito chifukwa cha kutentha kwake kochepa kwambiri pafupifupi -253°C.

Mapulogalamuwa akuphatikizapo:

• Zomera zothira madzi a haidrojeni
• Malo oyambitsira ndege
• Malo opangira mafuta a haidrojeni
• Malo ofufuzira kafukufuku
• Mapulojekiti obiriwira a haidrojeni

Popeza mamolekyu a haidrojeni ndi ang'onoang'ono kwambiri komanso oyenda kwambiri, kusunga mphamvu yoteteza kutentha ndikofunikira kwambiri. Mapaipi oteteza kutentha amathandizira kuchepetsa kutuluka kwa kutentha ndikuchepetsa kuuma kwa mpweya, zomwe zimapangitsa kuti akhale njira yabwino kwambiri yogwiritsira ntchito makina otumizira haidrojeni yamadzimadzi.

Mapangidwe apamwamba nthawi zambiri amakhala ndi zotetezera kutentha zambiri, zomangamanga zapadera zothandizira, ndi kuchuluka kwa vacuum komwe kumayendetsedwa mosamala kuti kukwaniritse kutentha komwe kumafunikira.

Kugwiritsa Ntchito Kusamutsa Nayitrogeni Yamadzimadzi

Nitrojeni yamadzi imagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kuphatikizapo:

• Kupanga ma semiconductor
• Ukadaulo wa zamoyo ndi sayansi ya moyo
• Kupanga mankhwala
• Kukonza chakudya ndi kuzizira
• Kugawa gasi m'mafakitale

M'malo amenewa, mapaipi otetezedwa ndi vacuum amanyamula LN₂ kuchokera ku matanki osungiramo zinthu zambiri kupita ku zida ndi malo opangira zinthu m'fakitale yonse.

Kugwiritsa ntchito makina a VIP kumathandiza:

• Sungani kuperekedwa kwa madzi kokhazikika
• Chepetsani kugwiritsa ntchito nayitrogeni
• Sinthani kusinthasintha kwa njira
• Ndalama zotsika zogwirira ntchito
• Chepetsani kupangika kwa ayezi ndi zofunikira pakusamalira

Pa malo akuluakulu opangira zinthu zamagetsi, mapaipi otetezedwa ndi vacuum nthawi zambiri amatalika mamita mazana ambiri kuti atsimikizire kuti nayitrogeni yamadzimadzi yoyera kwambiri imapezeka nthawi zonse.

Zigawo za Dongosolo Lonse Losamutsira Cryogenic

Netiweki yosamutsira madzi ya cryogenic imaphatikizapo zambiri osati kungoyika mapaipi otetezedwa. Kutengera ndi momwe ikugwiritsidwira ntchito, makinawo angaphatikizeponso:

• Ma valve otetezedwa ndi vacuum
• Mapayipi osinthika otetezedwa ndi vacuum
• Zolekanitsa magawo
• Zipangizo zowongolera kuthamanga kwa magazi
• Malumikizidwe okulitsa
• Zipangizo zowunikira vacuum
• Machitidwe okonza vacuum amphamvu

Zigawozi zimagwirira ntchito limodzi kuti zitsimikizire kuti zikugwira ntchito bwino, kuyenda bwino, komanso kudalirika kwa nthawi yayitali.

Ubwino wa Mapaipi Otetezedwa ndi Vacuum

Mapaipi otetezedwa ndi vacuum akhala njira yabwino kwambiri yosamutsira madzi a cryogenic chifukwa amapereka zabwino zingapo zofunika:

Kutsika kwa Kutentha kwa Kutentha

Malo opumulirako mpweya amapereka chitetezo chabwino kwambiri cha kutentha, kuchepetsa kusamutsa kutentha kuchokera ku chilengedwe.

Kutayika Kotsika kwa Zamalonda

Kutsika kwa kutentha kumatanthauza kuchepa kwa nthunzi komanso kuchepa kwa kuchuluka kwa kuwira.

Kukhazikika kwa Njira

Kusunga madzi a cryogenic mu gawo limodzi kumathandiza kuonetsetsa kuti kuthamanga ndi kuyenda bwino kwa madzi kukhazikika.

Kuchuluka kwa Mphamvu Zogwira Ntchito

Kuchepa kwa kutayika kwa zinthu kumatanthauza kuchepetsa ndalama zogwirira ntchito komanso kukonza bwino magwiridwe antchito a makina.

Kudalirika Kwanthawi Yaitali

Mapaipi opangidwa bwino oteteza mpweya m'malo otayidwa bwino amapereka kutentha koyenera kwa zaka zambiri akugwira ntchito.

Mapeto

Kunyamula bwino komanso kotetezeka kwa zakumwa zoziziritsa kukhosi kumadalira kuchepetsa kutentha komwe kumasamutsidwa panthawi yonse yosamutsira. Kaya mukugwiritsa ntchito LNG, nayitrogeni yamadzimadzi, mpweya wamadzimadzi, kapena haidrojeni yamadzimadzi, kusunga kutentha kochepa ndikofunikira kuti musunge bwino zinthu ndikuchepetsa kutayika kwa ntchito.

Mapaipi otetezedwa ndi vacuum akhala muyezo wa makampani chifukwa amapereka mphamvu yabwino kwambiri yotenthetsera, mphamvu zochepa zowiritsa, magwiridwe antchito abwino, komanso ntchito yodalirika kwa nthawi yayitali. Pamene kufunikira kwa ntchito zotetezedwa ndi cryogenic kukupitilira kukula m'magawo amagetsi, gasi wamafakitale, sayansi ya zamoyo, ndi semiconductor, ukadaulo wa mapaipi otetezedwa ndi vacuum udzakhalabe gawo lofunikira kwambiri pa zomangamanga zamakono zotetezedwa ndi cryogenic.
