Tam sim no, cov thev naus laus zis uas siv hydrogen ntau tshaj plaws suav nrog kev cia siab siab gaseous, cryogenic kua cia, thiab cov khoom hauv lub xeev cia. Ntawm cov no, lub zog siab gaseous cia tau tshwm sim raws li cov cuab yeej paub tab tshaj plaws vim nws tus nqi qis, kev siv hluav taws xob sai sai, kev siv hluav taws xob tsawg, thiab cov qauv yooj yim, ua rau nws nyiam hydrogen cia technology.
Plaub Hom Hydrogen Cia Tank:
Sib nrug los ntawm qhov tshwm sim hom V tag nrho cov tso tsheb hlau luam uas tsis muaj cov khoom siv sab hauv, plaub hom hydrogen cia tso tsheb hlau luam tau nkag mus rau hauv kev ua lag luam:
1.Type I tag nrho cov hlau tso tsheb hlau luam: Cov tso tsheb hlau luam no muaj peev xwm loj dua ntawm kev ua haujlwm siab xws li 17.5 txog 20 MPa, nrog cov nqi qis dua. Lawv siv nyob rau hauv qhov tsawg kawg nkaus rau CNG (compressed natural gas) tsheb thiab tsheb npav.
2.Type II hlau-lined composite tso tsheb hlau luam: Cov tso tsheb hlau luam ua ke cov hlau liners (feem ntau yog hlau) nrog cov ntaub ntawv sib xyaw ua ke hauv qhov kev taw qhia hoop. Lawv muab lub peev xwm loj ntawm kev ua haujlwm siab ntawm 26 thiab 30 MPa, nrog cov nqi nruab nrab. Lawv tau dav siv rau CNG daim ntawv thov tsheb.
3.Type III tag nrho-composite tso tsheb hlau luam: Cov tso tsheb hlau luam no muaj lub peev xwm me dua ntawm kev ua haujlwm siab ntawm 30 thiab 70 MPa, nrog rau cov hlua hlau (steel / aluminium) thiab cov nqi siab dua. Lawv pom cov ntawv thov hauv lub teeb yuag hydrogen roj cell tsheb.
4.Type IV yas-lined composite tso tsheb hlau luam: Cov tso tsheb hlau luam no muaj peev xwm me dua ntawm kev ua haujlwm siab ntawm 30 thiab 70 MPa, nrog cov khoom siv xws li polyamide (PA6), high-density polyethylene (HDPE), thiab polyester plastics (PET) .
Qhov zoo ntawm Hom IV Hydrogen Storage Tanks:
Tam sim no, Hom IV tso tsheb hlau luam tau siv dav hauv kev lag luam thoob ntiaj teb, thaum Hom III tso tsheb hlau luam tseem ua tus thawj coj ntawm kev lag luam hydrogen cia khoom lag luam.
Nws paub zoo tias thaum hydrogen siab tshaj 30 MPa, irreversible hydrogen embrittlement yuav tshwm sim, ua rau corrosion ntawm cov hlau liner thiab ua rau tawg thiab puas. Qhov xwm txheej no tuaj yeem ua rau hydrogen to thiab tawg tom qab.
Tsis tas li ntawd, aluminium hlau thiab carbon fiber nyob rau hauv txheej winding muaj qhov sib txawv, ua rau kev sib cuag ncaj qha ntawm aluminium liner thiab carbon fiber winding raug rau corrosion. Txhawm rau tiv thaiv qhov no, cov kws tshawb fawb tau ntxiv cov txheej txheem paug tawm ntawm cov liner thiab winding txheej. Txawm li cas los xij, qhov no ua rau qhov hnyav tag nrho ntawm hydrogen cia tso tsheb hlau luam, ntxiv rau cov teeb meem logistical thiab cov nqi.
Kev ruaj ntseg Hydrogen Tsheb thauj mus los: Ib qho tseem ceeb:
Piv rau Hom III tso tsheb hlau luam, Hom IV hydrogen cia tso tsheb hlau luam muaj qhov zoo ntawm kev nyab xeeb. Ua ntej, Hom IV tso tsheb hlau luam siv cov khoom siv tsis yog xim hlau uas muaj cov khoom sib xyaw xws li polyamide (PA6), high-density polyethylene (HDPE), thiab polyester plastics (PET). Polyamide (PA6) muaj lub zog tensile zoo heev, cuam tshuam tsis kam, thiab kub melting kub (txog 220 ℃). High-density polyethylene (HDPE) muaj qhov ua tau zoo thaum tshav kub kub ua haujlwm, ib puag ncig kev ntxhov siab tawg tsis kam, toughness, thiab cuam tshuam tsis kam. Nrog rau kev txhawb nqa ntawm cov khoom siv yas sib xyaw, Hom IV tso tsheb hlau luam ua kom pom kev zoo dua rau hydrogen embrittlement thiab corrosion, ua rau lub neej ntev kev pab cuam thiab txhim khu kev ruaj ntseg. Qhov thib ob, lub teeb yuag ntawm cov khoom siv yas sib xyaw txo qhov hnyav ntawm cov tso tsheb hlau luam, ua rau cov nqi qis dua.
Xaus:
Kev sib xyaw ntawm cov khoom sib xyaw hauv Hom IV hydrogen cia tso tsheb hlau luam sawv cev rau kev nce qib tseem ceeb hauv kev txhim kho kev nyab xeeb thiab kev ua haujlwm. Kev txais yuav cov khoom siv tsis yog xim hlau, xws li polyamide (PA6), high-density polyethylene (HDPE), thiab polyester plastics (PET), muab kev tiv thaiv zoo rau hydrogen embrittlement thiab corrosion. Ntxiv mus, cov yam ntxwv ntawm lub teeb yuag ntawm cov khoom siv yas sib xyaw no ua rau txo qhov hnyav thiab txo nqi logistical. Raws li Hom IV tso tsheb hlau luam tau txais kev siv dav hauv kev lag luam thiab Hom III tso tsheb hlau luam tseem muaj zog, kev txhim kho txuas ntxiv ntawm hydrogen cia thev naus laus zis yog qhov tseem ceeb rau kev paub txog tag nrho cov peev txheej ntawm hydrogen ua lub zog huv.
