Nei uchivakira tangi rakakura kudaro rekuchengetedza gasi?
Munguva pfupi yapfuura, matatu makuru makuru epasi rose akavakwa muChina, uye matura avo akasvika 270,000 cubic metres patangi.Vatatu vanoshanda panguva imwe chete vanogona kupa vanhu mamiriyoni makumi matanhatu negasi kwemwedzi miviri.Nei tichifanira kuvaka tangi rakakura kudaro rekuchengetedza gasi?Nzira itsva yesimba rakanyungudutswa gasi remusikirwo
Senyika huru yekushandisa simba, China yagara ichivimba nemarasha senzvimbo huru yesimba.Nekudaro, nekupokana kuri kuwedzera kukuru pakati pekusimudzira hupfumi nekusvibiswa kwezvakatipoteredza, kusvibiswa kwemhepo uye dzimwe njodzi dzezvakatipoteredza dzinokonzerwa nekushandiswa kwemarasha dziri kuramba dzichiwedzera, uye chimiro chesimba chinoda kushandurwa nekukurumidza kuita yakaderera-kabhoni, ine hushamwari uye yakachena.Gasi remusikirwo isimba rakaderera-kabhoni uye rakachena simba, asi rakaoma kuchengeta nekutakura, uye rinowanzo shandiswa segasi rakawanda sezvarinocherwa.
Mushure mekutevedzana kwe-ultra-low tembiricha liquefaction yegasi rechisikigo, liquefied natural gas (LNG) inoumbwa.Chinhu chayo chikuru methane.Mushure mekupisa, inosvibisa mhepo zvishoma uye inopa kupisa kwakawanda.Naizvozvo, LNG isimba repamusoro-soro uye rinozivikanwa seyakachena kwazvo pasi pesimba rezvicherwa pasi.Liquefied natural gas (LNG) yakasvibira, yakachena, yakachengeteka uye inoshanda, uye yakanakira kuchengetedza nekufambisa.Inoshandiswa zvakanyanya kupfuura gasi rechisikigo, uye nyika dzine kuchengetedzwa kwemamiriro ekunze pasi rose dziri kukurudzira kushandiswa kweLNG.
Panguva imwecheteyo, huwandu hwegasi rakanyungudutswa hunenge chikamu chimwe muzvitanhatu chegasi, zvinoreva kuti kuchengetedza 1 cubic mita yegasi rakanyungudutswa rakaenzana nekuchengetedza 600 cubic metres yegasi remusikirwo, iro rine kukosha kukuru pakuona. gasi rinowanikwa munyika.
Muna 2021, China yakaunza 81.4 miriyoni matani eLNG, ichiiita iyo yakakura kwazvo LNG mutengesi munyika.Tichachengeta sei LNG yakawanda kudaro?
Maitiro ekuchengeta liquefied natural gasi
Liquefied natural gasi rinoda kuchengetwa pa -162 ℃ kana pasi.Kana kupisa kwezvakatipoteredza kukapinda mukati, tembiricha yegasi rakanyungudutswa rinokwira, zvichikonzera kukuvadzwa kwepaipi, mavharuvhu uye kunyange matangi.Kuti uve nechokwadi chekuchengetwa kweLNG, tangi yekuchengetera inofanirwa kuchengetwa ichitonhora kunge firiji hombe.
Sei uchigadzira tangi yakakura-yegasi?Chikonzero chikuru chekusarudza kuvaka 270,000-square-metres super-hombe yekuchengetera gasi tank ndechekuti hombe-inoenda mugungwa LNG inotakura ine huwandu hunosvika zviuru mazana maviri nemakumi manomwe neshanu emamita.Kana ngarava yeLNG ichiendeswa kuchiteshi, inogona kutakurwa yakananga mu super gasi rekuchengetedza tangi kuti isangane nezvinodiwa zvekuchengetera.Iyo yepamusoro, yepakati uye pasi peiyo super gasi yekuchengetedza tangi yakagadzirwa nehungwaru.Donje inotonhora nehupamhi hwemamita 1.2 kumusoro inoparadzanisa mweya mutangi kubva padenga kuderedza convection;Pakati petangi yakaita semupunga wemupunga, wakazadzwa nezvinhu zvine low thermal conductivity uye yakanaka thermal insulation performance;Pazasi petangi panoshandisa zvidimbu zvishanu zvezvitsva zvinopisa zvekupisa zvidhinha-foam girazi zvidhinha kuti ive nechokwadi chekuchengeta kutonhora kwepasi petangi.Panguva imwecheteyo, tembiricha yekuyera system inomiswa kuti ipe alarm munguva kana paine kutonhora kunodonha.Kudzivirirwa kwese-kutenderera kunogadzirisa dambudziko rekuchengetedza rakanyungudutswa gasi rechisikigo.
Zvakaoma kwazvo kugadzira uye kuvaka tangi yakakura kudaro yekuchengetedza mune ese maficha, pakati peiyo dhome kushanda kweLNG yekuchengetedza tank ndiyo yakanyanya kuoma, yakaoma uye ine njodzi chikamu mukugadzika nekuvaka.Kune "hombe MAC" dome yakadaro, vatsvakurudzi vanoisa mberi tekinoroji yekushandisa ye "kusimudza gasi".Kusimudza mhepo "rudzi rutsva rwekusimudza tekinoroji, iyo inoshandisa 500,000 cubic metres yemhepo inopeperetswa nefani kusimudza zvishoma nezvishoma dome retangi rekuchengetera gasi kunzvimbo yakafanotemerwa kumusoro."Zvakafanana nekuzadza 700 miriyoni mabhora enhabvu mutangi rekuchengetera mweya.Kuti vafuridze bhemoti iyi kusvika paurefu hwemamita makumi matanhatu, vavaki vakaisa mabhomba mana e110 kW sesimba remagetsi.Kana iyo dome ikakwira kune yakafanotemerwa chinzvimbo, inofanirwa kusungirirwa kumusoro kwetangi remadziro pasi pemamiriro ekuchengetedza kudzvanywa mutangi, uye pakupedzisira kusimudza denga kunopedzwa.
