Cryogenic tso tsheb hlau luam yog qhov tseem ceeb rau khaws cov ntaub ntawv ntawm qhov kub tsis tshua muaj siab, tseem ceeb heev rau ntau yam kev tshawb fawb thiab kev lag luam. Tab sis yuav ua li cas cov tso tsheb hlau luam tswj qhov kub tsis tshua muaj? Cia peb tshawb nrhiav cov haujlwm sab hauv ntawm cov thawv zoo kawg no.
Cryogenic tso tsheb hlau luam yog tsim los tswj qhov kub thiab txias hauv qab -150 degree, txawm tias qis dua li -253 degree hauv cov kua nitrogen. Tus yuam sij rau lawv lub peev xwm ua kom txias yog nyob rau hauv cov khoom siv hauv lawv cov kev tsim kho thiab cov txheej txheem tshwj xeeb uas ua haujlwm.
Ua ntej, lub tank nws tus kheej feem ntau yog ua los ntawm tuab, ob-walled stainless hlau. Cov khoom siv no tsis yog tsuas yog muab lub zog tab sis kuj ua raws li cov rwb thaiv tsev zoo heev, tiv thaiv cua sov los ntawm kev nkag los yog khiav tawm. Kev tsim ob phab ntsa tsim ib qho chaw nqus ntawm cov phab ntsa, ntxiv kom txo tau cov cua sov.
Hauv lub tank, cov kua dej cryogenic xws li kua nitrogen lossis kua helium khaws cia. Thaum cov kua dej cryogenic tau tso rau hauv lub tank, nws nqus cua sov los ntawm ib puag ncig ib puag ncig, txias nws mus rau qhov xav tau kub. Cov kua dej cryogenic tseem nyob hauv cov kua hauv lub xeev ntawm qhov kub thiab txias vim nws qhov tsis tshua muaj vapor siab.
Txhawm rau tswj qhov kub thiab txias, cov tso tsheb hlau luam cryogenic tau nruab nrog lub tshuab nqus tsev thiab lub tshuab hluav taws xob sab hauv. Lub tshav kub exchanger yog ib qho kev sib txuas ntawm cov kab hauv lub tank uas pab faib cov kua dej cryogenic sib npaug, ua kom cov cua txias tsis sib xws. Lub tsho nqus tsev vacuum ua kom ntseeg tau tias muaj cua sov tsawg heev los ntawm cov phab ntsa tank.
Tsis tas li ntawd, cov tso tsheb hlau luam cryogenic tuaj yeem muaj cov ntaub ntawv rwb thaiv tsev xws li fiberglass lossis perlite hauv ob sab hauv ntawm phab ntsa tank kom txo tau cov cua sov ntxiv. Qee lub tso tsheb hlau luam kuj muaj cov ntaub thaiv hluav taws xob sab hauv los tiv thaiv hluav taws xob hloov hluav taws xob.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov tso tsheb hlau luam cryogenic tsis yog tag nrho impervious rau tshav kub nkag. Thaum lub sij hawm, txawm tias tag nrho cov kev ntsuas rwb thaiv tsev nyob rau hauv qhov chaw, lub ambient kub yuav maj mam sov lub tank txheem. Yog li ntawd, kev saib xyuas tas li thiab qee zaus ntxiv ntawm cov kua cryogenic yog qhov tseem ceeb los tswj qhov kub thiab txias.
Cryogenic tso tsheb hlau luam muaj ntau daim ntawv thov tshaj li kev tshawb fawb lab. Lawv tau siv rau hauv kev lag luam xws li lub zog cia, qhov chaw lawv tuaj yeem ua haujlwm rau khaws cia liquefied natural gas (LNG) lossis hydrogen gas ntawm qhov kub thiab txias. Hauv kev kho mob, cov tso tsheb hlau luam cryogenic tau ua haujlwm rau khaws cov khoom pub dawb thiab cov hlab ntshav qia hlwb. Lawv kuj tseem siv tau rau hauv qhov chaw tshawb nrhiav, qhov chaw uas lawv tseem ceeb heev rau kev tswj cov cuab yeej muag thiab kev sim ntawm qhov kub thiab txias.
Hauv kev xaus, cov tso tsheb hlau luam cryogenic tshuav lawv lub peev xwm ua kom txias zoo kawg nkaus rau kev sib xyaw ntawm cov khoom siv qib siab, kev tsim qauv zoo, thiab kev saib xyuas tas li. Lawv lub peev xwm los tswj cov huab cua txias ua rau lawv tsis yog qhov xav paub xwb tab sis yog qhov tseem ceeb hauv ntau yam kev tshawb fawb thiab kev lag luam, thawb cov ciam teb ntawm tib neeg kev paub thiab kev tsim kho tshiab.
