Zamadzimadzi za cryogenic monga nayitrogeni wamadzimadzi (LN2), hydrogen yamadzimadzi (LH2), ndi gasi wachilengedwe (LNG) ndizofunikira m'mafakitale osiyanasiyana, kuyambira ntchito zamankhwala mpaka kupanga mphamvu. Kayendetsedwe ka zinthu zomwe sizimatenthedwa bwinozi zimafuna makina apadera kuti azisunga kuzizira kwambiri komanso kuti asafufuze. Imodzi mwamatekinoloje ogwira mtima kwambiri onyamula zakumwa za cryogenic ndi vacuum insulated pipeline. Pansipa, tiwona momwe makinawa amagwirira ntchito komanso chifukwa chake ali ofunikira pakunyamula zakumwa za cryogenic mosatetezeka.

Vuto Loyendetsa Zamadzimadzi za Cryogenic

Zakumwa za cryogenic zimasungidwa ndikunyamulidwa pa kutentha kosachepera -150 ° C (-238 ° F). Pakutentha kotereku, zimakonda kusanduka nthunzi msanga ngati zitakumana ndi malo ozungulira. Chovuta chachikulu ndikuchepetsa kutengera kutentha kuti zinthu izi zisungidwe m'malo ake amadzimadzi panthawi yoyendetsa. Kuwonjezeka kulikonse kwa kutentha kungapangitse kuti vaporization ikhale yofulumira, zomwe zimapangitsa kuti zinthu ziwonongeke komanso zoopsa zomwe zingateteze chitetezo.

Vacuum Insulated Pipeline: Chinsinsi cha Kuyenda Mwachangu

Vacuum insulated mapaipi(VIPs) ndi yankho lofunikira pakunyamula zakumwa za cryogenic pamtunda wautali ndikuchepetsa kutentha. Mapaipiwa ali ndi zigawo ziwiri: chitoliro chamkati, chomwe chimanyamula madzi a cryogenic, ndi chitoliro chakunja chomwe chimatsekera chitoliro chamkati. Pakati pa zigawo ziwirizi pali vacuum, yomwe imakhala ngati chotchinga chotchinga chochepetsera kutentha ndi kutentha. Thevacuum insulated pipelineteknoloji imachepetsa kwambiri kutaya kwa kutentha, kuonetsetsa kuti madziwo amakhalabe pa kutentha kofunikira paulendo wake wonse.

Kugwiritsa ntchito LNG Transportation

Liquefied natural gas (LNG) ndi gwero lodziwika bwino lamafuta ndipo liyenera kunyamulidwa pa kutentha kochepera -162°C (-260°F).Vacuum insulated mapaipiamagwiritsidwa ntchito kwambiri m'malo a LNG ndi ma terminals kusuntha LNG kuchokera ku matanki osungirako kupita ku zombo kapena zotengera zina. Kugwiritsiridwa ntchito kwa ma VIP kumatsimikizira kutentha pang'ono, kuchepetsa mapangidwe a boil-off gas (BOG) ndi kusunga LNG m'malo ake amadzimadzi panthawi yotsitsa ndi kutsitsa ntchito.

Liquid Hydrogen ndi Liquid Nitrogen Transportation

Mofananamo,vacuum insulated mapaipindi zofunika kwambiri pa kayendedwe ka madzi hydrogen (LH2) ndi madzi asafe (LN2). Mwachitsanzo, hydrogen yamadzimadzi imagwiritsidwa ntchito kwambiri pofufuza mlengalenga ndi ukadaulo wama cell cell. Malo ake owira otsika kwambiri -253 ° C (-423 ° F) amafunikira machitidwe apadera oyendera. Ma VIP amapereka njira yabwino yothetsera, kulola kuyenda kotetezeka komanso kothandiza kwa LH2 popanda kutaya kwakukulu chifukwa cha kutentha kwa kutentha. Nayitrogeni yamadzimadzi, yomwe imagwiritsidwa ntchito kwambiri pazachipatala ndi mafakitale, imapindulanso ndi VIPs, kuonetsetsa kuti kutentha kwake kukhazikika panthawi yonseyi.

Kutsiliza: Udindo waVacuum Insulated mapaipi mu Tsogolo la Cryogenics

Pamene mafakitale akupitiriza kudalira zakumwa za cryogenic, vacuum insulated mapaipiadzakhala ndi gawo lofunikira kwambiri pakuwonetsetsa kuti mayendedwe awo azikhala otetezeka komanso abwino. Ndi kuthekera kwawo kuchepetsa kutentha, kuteteza kutayika kwa zinthu, ndikuwonjezera chitetezo, ma VIP ndi gawo lofunikira kwambiri pakukula kwa cryogenic. Kuchokera ku LNG kupita ku hydrogen yamadzimadzi, ukadaulo uwu umatsimikizira kuti zamadzimadzi zotsika zimatha kunyamulidwa popanda kuwononga chilengedwe komanso kuchita bwino kwambiri.
