Kev khaws cia thiab kev thauj mus los ntawm cov kua hydrogen yog lub hauv paus ntawm kev nyab xeeb, ua haujlwm tau zoo, kev siv loj thiab tus nqi qis ntawm cov kua hydrogen, thiab tseem yog tus yuam sij los daws qhov kev thov ntawm hydrogen technology txoj kev.
 
Kev khaws cia thiab kev thauj mus los ntawm cov kua hydrogen tuaj yeem muab faib ua ob hom: lub thawv ntim khoom thiab kev thauj mus los. Nyob rau hauv daim ntawv ntawm cov qauv cia, spherical cia tank thiab cylindrical cia tank feem ntau yog siv rau lub thawv cia thiab tsheb thauj mus los. Nyob rau hauv daim ntawv ntawm kev thauj mus los, kua hydrogen trailer, kua hydrogen railway tank tsheb thiab kua hydrogen tank nkoj yog siv.
 
Ntxiv rau kev xav txog qhov cuam tshuam, kev vibration thiab lwm yam cuam tshuam rau hauv cov txheej txheem ntawm kev thauj mus los ua kua, vim qhov kub ntawm cov kua hydrogen tsawg (20.3K), me me latent cua sov ntawm vaporization thiab cov yam ntxwv yooj yim evaporation, lub thawv ntim thiab kev thauj mus los yuav tsum. txais yuav cov txheej txheem nruj kom txo tau cov cua sov, lossis txais yuav tsis muaj kev puas tsuaj thiab kev thauj mus los, kom txo cov qib ntawm vaporization ntawm cov kua hydrogen kom tsawg lossis xoom, txwv tsis pub nws yuav ua rau lub tank siab. Ua rau overpressure txaus ntshai los yog blowout poob. Raws li pom nyob rau hauv daim duab hauv qab no, los ntawm qhov kev xav ntawm kev ua haujlwm, cov kua hydrogen cia thiab kev thauj mus los tsuas yog siv cov thev naus laus zis los ntawm adiabatic kom txo tau cov cua sov thiab cov tub yees siv tshuab ua haujlwm rau lub hauv paus no kom txo tau cov cua sov los yog tsim kom muaj cua txias ntxiv.
 
Raws li lub cev thiab tshuaj lom neeg cov khoom ntawm cov kua hydrogen nws tus kheej, nws txoj kev khaws cia thiab kev thauj mus los muaj ntau yam zoo dua li kev siv lub zog siab gaseous hydrogen cia hom dav siv hauv Suav teb, tab sis nws cov txheej txheem ntau lawm kuj ua rau nws muaj qee qhov tsis zoo.
 
Loj cia hnyav piv, yooj yim cia thiab thauj thiab tsheb
Piv nrog rau gaseous hydrogen cia, qhov zoo tshaj plaws ntawm cov kua hydrogen yog nws qhov siab ceev. Qhov ceev ntawm cov kua hydrogen yog 70.8kg / m3, uas yog 5, 3 thiab 1.8 npaug ntawm 20, 35, thiab 70MPa high-pressure hydrogen feem. Yog li ntawd, kua hydrogen yog tsim nyog rau loj-scale cia thiab kev thauj mus los ntawm hydrogen, uas yuav daws tau cov teeb meem ntawm hydrogen zog cia thiab tsheb thauj mus los.
 
Tsawg cia siab, yooj yim kom muaj kev nyab xeeb
Cov kua hydrogen cia nyob rau hauv lub hauv paus ntawm rwb thaiv tsev los xyuas kom meej lub stability ntawm lub thawv, lub siab theem ntawm txhua hnub cia thiab kev thauj mus los yog tsawg (feem ntau qis dua 1MPa), qis dua qhov siab ntawm high-pressure gas thiab hydrogen cia thiab kev thauj mus los, uas yooj yim dua los xyuas kom muaj kev nyab xeeb hauv kev ua haujlwm txhua hnub. Ua ke nrog cov yam ntxwv ntawm cov kua hydrogen loj cia qhov hnyav piv, yav tom ntej kev txhawb nqa loj ntawm hydrogen zog, kua hydrogen cia thiab kev thauj mus los (xws li cov chaw nres tsheb hydrogen hydrogenation) yuav muaj kev nyab xeeb kev ua haujlwm hauv nroog nrog cov tsev loj, Cov pej xeem tuab thiab thaj av siab tus nqi, thiab lub kaw lus siab yuav them rau ib qho chaw me dua, uas yuav tsum tau tus nqi me me ntawm kev nqis peev thiab cov nqi ua haujlwm.
 
High purity ntawm vaporization, ua tau raws li qhov yuav tsum tau muaj ntawm lub davhlau ya nyob twg
Lub ntiaj teb no txhua xyoo noj ntawm high purity hydrogen thiab ultra-ntshiab hydrogen yog loj, tshwj xeeb tshaj yog nyob rau hauv lub electronics kev lag luam (xws li semiconductors, electro-nqus khoom, silicon wafers, optical fiber manufacturing, thiab lwm yam) thiab roj cell teb, qhov twg noj ntawm high purity hydrogen thiab ultra-ntshiab hydrogen yog tshwj xeeb tshaj yog loj. Tam sim no, qhov zoo ntawm ntau cov khoom siv hydrogen tsis tuaj yeem ua tau raws li cov kev cai nruj ntawm qee cov neeg siv kawg ntawm purity ntawm hydrogen, tab sis purity ntawm hydrogen tom qab vaporization ntawm cov kua hydrogen tuaj yeem ua tau raws li qhov yuav tsum tau ua.
 
Liquefaction cog muaj kev nqis peev siab thiab kev siv zog siab
Vim yog kev lag luam hauv kev tsim cov khoom siv tseem ceeb thiab cov thev naus laus zis xws li hydrogen liquefaction txias thawv, tag nrho cov khoom siv hydrogen liquefaction hauv thaj av aerospace hauv tebchaws tau monopolized los ntawm cov tuam txhab txawv teb chaws ua ntej lub Cuaj Hli 2021. Cov khoom siv loj loj hydrogen liquefaction core yuav raug cuam tshuam rau kev lag luam txawv teb chaws. cov cai (xws li Export Administration Regulations of the US Department of Commerce), uas txwv tsis pub xa tawm cov cuab yeej siv thiab txwv tsis pub muaj kev sib pauv. Qhov no ua rau cov cuab yeej pib nqis peev ntawm hydrogen liquefaction cog loj, ua ke nrog cov kev thov me me rau pej xeem cov kua hydrogen, qhov ntsuas ntawm daim ntawv thov tsis txaus, thiab cov peev txheej nce qeeb. Yog li ntawd, chav tsev tsim hluav taws xob noj cov kua hydrogen yog siab dua li cov pa roj hydrogen siab.
 
Muaj evaporation poob hauv cov txheej txheem ntawm cov kua hydrogen cia thiab kev thauj mus los
Tam sim no, nyob rau hauv cov txheej txheem ntawm cov kua hydrogen cia thiab tsheb thauj mus los, evaporation ntawm hydrogen los ntawm tshav kub to taub yog pib kho los ntawm venting, uas yuav ua rau ib tug tej yam degree ntawm evaporation poob. Nyob rau hauv lub neej yav tom ntej hydrogen zog cia thiab kev thauj mus los, kev ntsuas ntxiv yuav tsum tau ua kom rov qab tau cov pa roj hydrogen ib nrab los daws qhov teeb meem ntawm kev siv txo qis los ntawm qhov cua ncaj qha.
 
HL Cryogenic khoom
HL Cryogenic Equipment uas tau tsim nyob rau hauv 1992 yog ib hom lag luam koom nrog HL Cryogenic Equipment Company Cryogenic Equipment Co., Ltd. HL Cryogenic Equipment tau cog lus rau kev tsim thiab tsim khoom ntawm High Vacuum Insulated Cryogenic Piping System thiab cov cuab yeej txhawb nqa kom tau raws li ntau yam kev xav tau ntawm cov neeg siv khoom. Lub Nqus Tsev Insulated Yeeb Nkab thiab Flexible Hose yog tsim nyob rau hauv lub tshuab nqus tsev siab thiab ntau txheej txheej multi-screen tshwj xeeb insulated cov ntaub ntawv, thiab dhau los ntawm cov txheej txheem nruj heev thiab kev kho lub tshuab nqus tsev siab, uas yog siv rau kev hloov cov kua oxygen, kua nitrogen. , kua argon, kua hydrogen, kua helium, liquefied ethylene gas LEG thiab liquefied natural gas LNG.
