LNG Ubushyuhe Buke Ububiko bwa Tank Urubuga

HOUIbigega byo kubika PU LNG biboneka muburyo bubiri bwo kubika: kubika ifu ya vacuum hamwe no guhinduranya umuyaga mwinshi. HOUIbigega byo kubika PU LNG biza muburyo butandukanye kuva kuri metero kibe 30 kugeza 100. Igipimo cyuka cyumubyimba wifu ya vacuum hamwe nubushyuhe bwo hejuru bwa vacuum ≤ 0.115. Birakwiriye kuri sitasiyo zitandukanye za LNG na sitasiyo ya lisansi.

Ikigega cyumubiri wa HOUIbigega byo kubika PU LNG bikurikiza igishushanyo mbonera nubukorikori bwibigega bya cryogenic. Ikigega cy'imbere hamwe n'umuyoboro w'ikigega cyo kubikamo bikozwe mu cyuma cya S30408. Imiyoboro iri muri vacuum interlayer yikigega cyo kubikamo ifata uburebure bwurukuta buringaniye hamwe nuduce twose dusudira, bifite ubushobozi bwindishyi zihagije zo guhuza no kwaguka kwamashyanyarazi no kugabanuka, byemeza ko imiyoboro idakonja kandi igikonoshwa cyo hanze ntigicika kubushyuhe buke. Ibikoresho byokwirinda bifite coefficente yubushyuhe buke bwumuriro, gukora cyane hamwe no kurwanya imirasire.

Mugihe cyo kubyaza umusaruro HOUIkigega cyo kubika PU LNG, ibikoresho bigezweho kandi byuzuye byuzuzwa, kandi inzira yo guhinduranya iragenzurwa cyane kugirango harebwe ubukana hamwe nuburinganire. Hagati aho, ibyuma bya molekile bitumizwa mu mahanga hamwe na adsorbents ya chimique byubatswe mu cyuho. Nyuma yubuso bwa HOUIbigega byo kubika PU LNG byanditseho umucanga, byatewe irangi rya HEMPEL ryera rya epoxy yera, rifite ibikorwa byo gukingira UV, rigabanya ihererekanyabubasha ry’imishwarara, kandi ryemeza ko icyuho gihagarara hamwe na kirogenike yo kubika ikigega cyo kubika mu buzima bwakazi.

Hejurutwe HOUPU LNG ibigega byo kubika,hari inteko ebyiri z'umutekano zashyizweho kugirango zuzuze ibisabwa byo gusohora umutekano haba mubihe bitari umuriro ndetse numuriro. HOUIbigega byo kubika PU LNG bifashisha ibikoresho bya vacuum gauge bidaturika hamwe nibifuniko byihariye birinda umutekano, bikarinda umutekano muke nibikorwa byiza. Ikoresha ibicuruzwa byatumijwe mu mahanga bikuze, hamwe na vacuum gauge ya matsinda hamwe na vacuum diaphragm yohanagura. Byongeye kandi,twe HOUIbigega byo kubika PU LNG bifite ibikoresho byumuvuduko wikibuga hamwe nibikoresho byerekana urwego rwamazi, byorohereza ikusanyamakuru no gukurikirana umutekano mugihe gikora. Buri kimwe muritwe HOUIbigega bya PU LNG cryogenic bikorerwa neza kandi bigenzurwa neza mbere yo kuva muruganda. Mbere yo kugenda, helium mass spectrometry yameneka ikoreshwa mugutahura ibimeneka, igenzura rya X-100% rikorwa ku ngingo zifatanije, ibizamini byinjira 100% bikorerwa kumpande zinguni, kandi buri gikoresho cyibikoresho ni azote isukuye, yabanje gukonjeshwa na azote yuzuye, yuzuyemo azote kugirango ikingire, kandi yomekwe kumuhanda hamwe na kashe ya sisitemu. Gusa nyuma yo kwemeza ubwiza buhebuje ibyo bigega bigezwa kubakiriya neza.

Nkubu, ibigega bya LNG cryogenic bitangwa naHoupu Isuku Ingufu Zitsinda Co, Ltd.zagiye zikoreshwa cyane muri sitasiyo zirenga 3.000 LNG mu gihugu hose. Ingaruka ya vacuum insulation yibi bigega ni nziza kandi imikorere yayo irahagaze neza, ishimwe kandi ishimwa nabakiriya.
