Cov kua dej cryogenic xws li kua nitrogen (LN2), kua hydrogen (LH2), thiab roj av liquefied natural gas (LNG) yog qhov tseem ceeb hauv ntau yam lag luam, los ntawm kev siv kho mob mus rau kev tsim hluav taws xob. Kev thauj mus los ntawm cov khoom kub qis no xav tau cov txheej txheem tshwj xeeb los tswj lawv qhov kub thiab txias heev thiab tiv thaiv kev ua kom qhuav. Ib qho ntawm cov thev naus laus zis zoo tshaj plaws rau kev thauj cov kua dej cryogenic yog lub raj xa dej nqus tsevHauv qab no, peb yuav tshawb nrhiav seb cov kab ke no ua haujlwm li cas thiab vim li cas lawv thiaj li tseem ceeb rau kev thauj cov kua dej cryogenic kom muaj kev nyab xeeb.

Qhov Kev Sib Tw ntawm Kev Thauj Cov Kua Cryogenic

Cov kua dej cryogenic raug khaws cia thiab thauj mus rau qhov kub qis dua -150°C (-238°F). Thaum qhov kub qis li no, lawv feem ntau yuav yaj sai yog tias raug rau qhov chaw ib puag ncig. Qhov teeb meem tseem ceeb yog txo qhov kev hloov pauv cua sov kom cov tshuaj no nyob hauv lawv cov kua thaum thauj mus los. Txhua qhov kub nce tuaj yeem ua rau cov dej sai sai, ua rau cov khoom poob thiab muaj kev phom sij rau kev nyab xeeb.

Cov Kav Dej Uas Muaj Cov Khoom Siv Nqus Tsev: Qhov Tseem Ceeb Rau Kev Thauj Mus Los Zoo

Cov kav dej nqus tsev uas muaj cov rwb thaiv tsev(VIPs) yog ib qho kev daws teeb meem tseem ceeb rau kev thauj cov kua cryogenic hla kev deb thaum txo qis kev hloov pauv cua sov. Cov kav dej no muaj ob txheej: ib lub kav dej sab hauv, uas nqa cov kua cryogenic, thiab ib lub kav dej sab nraud uas kaw lub kav dej sab hauv. Nruab nrab ntawm ob txheej no yog lub tshuab nqus tsev, uas ua haujlwm ua lub thaiv rwb thaiv kom txo tau kev coj cua sov thiab kev tawg. Lublub raj xa dej nqus tsevthev naus laus zis txo qhov kev poob cua sov, ua kom cov kua tseem nyob ntawm qhov kub uas xav tau thoob plaws nws txoj kev mus.

Daim ntawv thov hauv LNG Kev Thauj Mus Los

Cov roj av liquefied natural gas (LNG) yog ib qho roj uas nrov heev thiab yuav tsum tau thauj mus rau qhov kub qis li -162°C (-260°F).Cov kav dej nqus tsev uas muaj cov rwb thaiv tsevsiv dav hauv LNG cov chaw thiab cov chaw nres tsheb kom txav LNG los ntawm cov thoob dej cia khoom mus rau cov nkoj lossis lwm lub thawv thauj khoom. Kev siv VIPs ua kom muaj cua sov tsawg kawg nkaus, txo cov pa roj boil-off (BOG) tsim thiab tswj LNG hauv nws lub xeev liquefied thaum lub sijhawm thauj khoom thiab tshem tawm.

Kev Thauj Mus Los Ua Kua Hydrogen Thiab Kua Nitrogen

Ib yam li ntawd,cov kav dej nqus tsevyog qhov tseem ceeb hauv kev thauj mus los ntawm cov kua hydrogen (LH2) thiab cov kua nitrogen (LN2). Piv txwv li, cov kua hydrogen feem ntau siv rau hauv kev tshawb nrhiav qhov chaw thiab kev siv roj cell. Nws qhov kub qis heev ntawm -253 ° C (-423 ° F) xav tau cov txheej txheem thauj mus los tshwj xeeb. VIPs muab cov kev daws teeb meem zoo tshaj plaws, tso cai rau kev txav mus los zoo thiab ua haujlwm ntawm LH2 yam tsis muaj kev poob loj vim yog kev hloov pauv cua sov. Cov kua nitrogen, siv dav hauv kev kho mob thiab kev siv hauv kev lag luam, kuj tau txais txiaj ntsig los ntawm VIPs, ua kom nws qhov kub ruaj khov thoob plaws hauv cov txheej txheem.

Xaus Lus: Lub Luag Haujlwm ntawmCov Kav Dej Nqus Tsev Uas Muaj Cov Khoom Siv Hluav Taws Xob yav tom ntej ntawm Cryogenics

Raws li kev lag luam txuas ntxiv vam khom cov kua cryogenic, cov kav dej nqus tsevyuav ua lub luag haujlwm tseem ceeb ntxiv rau kev ua kom lawv txoj kev thauj mus los muaj kev nyab xeeb thiab ua haujlwm tau zoo. Nrog lawv lub peev xwm los txo qhov hloov pauv cua sov, tiv thaiv kev poob khoom, thiab txhim kho kev nyab xeeb, VIPs yog ib qho tseem ceeb hauv kev lag luam cryogenic uas loj hlob tuaj. Txij li LNG mus rau cov kua hydrogen, cov thev naus laus zis no ua kom ntseeg tau tias cov kua kub qis tuaj yeem thauj tau nrog qhov cuam tshuam tsawg kawg nkaus rau ib puag ncig thiab ua haujlwm tau zoo tshaj plaws.
