LNG low-kub ua kua thauj semi-trailers yog cov khoom siv tshwj xeeb semi-trailer tshwj xeeb uas siv rau kev thauj khoom qis- kub xov xwm xws li cov roj ntsha liquefied. Nrog cov thermal rwb thaiv tsev, siab sealing thiab kev nyab xeeb siab, lawv cov qauv tsim thiab kev tsim khoom ncaj qha txiav txim siab kev thauj mus los thiab kev nyab xeeb ntawm kev ua haujlwm.
1. Basic Structure of LNG Low-Tub Kub Liquid Transport Semi-Trailer
1. High-nqus ntau- txheej winding rwb thaiv tsev interlayer
Raws li cov txheej txheem rwb thaiv tsev tseem ceeb, qhov interlayer no zoo thaiv cov cua sov sab nraud los ntawm kev nkag mus rau hauv lub tank, txo cov hluav taws xob hluav taws xob thiab cov hluav taws xob hluav taws xob, thiab ua rau LNG nyob rau hauv qis -kub kua lub xeev.
2. Sab hauv lub tank ntim
Siv ncaj qha sau LNG qis-kub kua. Ua los ntawm tshwj xeeb qis- kub resistant thiab siab - cov ntaub ntawv muaj zog, nws muab zoo heev uas tsis tshua muaj - kub stability thiab siab - bearing muaj peev xwm.
3. Lub thawv ntim khoom sab nraud
Ua haujlwm nrog lub thawv sab hauv los tsim qhov chaw kaw lub tshuab nqus tsev interlayer, muab kev tiv thaiv sab nraud ruaj khov rau txheej rwb thaiv tsev, thiab txhawb nqa tag nrho lub tank lub cev.
4. Pipeline system
Feem ntau yog siv rau kev thauj khoom thiab tshem tawm LNG qis - kua dej kub. Nruab nrog tshwj xeeb qis- qhov kub thiab txias li qub, cov pob qij txha thiab cov kav dej, nws ua kom muaj kev nyab xeeb thiab nrawm nrawm nruab nrab.
2. Core Insulation Structure thiab Key Technologies
1. High- nqus tsev ntau- txheej txheej rwb thaiv tsev
Nws yog ua los ntawm iav microfiber siab -cov khoom siv hluav taws xob cryogenic rwb thaiv tsev thiab iav fiber ntau winding, uas yog qhov tseem ceeb lav ntawm lub tsheb lub rwb thaiv tsev kev ua haujlwm.
2. Nqus tswj thiab adsorption ntaus ntawv
- Molecular sieve adsorbent yog ntsia rau sab txias ze rau lub thawv sab hauv kom nqus cov pa tawm ntawm cov khoom hauv lub tshuab nqus tsev interlayer.
- Palladium oxide adsorbent yog ntsia rau ntawm sab kub ze ntawm lub thawv sab nraud kom nqus tau cov hydrogen nkag mus rau hauv lub interlayer.
3. Tank Manufacturing thiab Vacuum Maintenance Process
1. Kev kho roj hloov
Ib tug loj npaum li cas ntawm tsis yog{0}}condensable gas nyob rau hauv lub multi- txheej rwb thaiv tsev qhov chaw. CO₂ roj hloov yuav tsum tau ua nyob rau hauv ntau lawm los txhim kho interlayer huv si.
2. Cua sov-pab desorption txheej txheem
Tom qab sau CO₂, cua sov yog siv los ua kom nrawm nrawm ntawm cov pa adsorbed thiab ntxiv kom ruaj khov interlayer nqus tsev vacuum thiab ua haujlwm ntev -.
