Cryogenic zvinwiwa senge liquid nitrogen (LN2), liquid hydrogen (LH2), uye liquefied natural gas (LNG) yakakosha mumaindasitiri akasiyana siyana, kubva pakushandisa pakurapa kusvika pakugadzira simba. Kufambiswa kwezvinhu izvi zvinodzikira-pasi zvinoda masisitimu ane hunyanzvi kuchengetedza kutonhora kwazvo uye kudzivirira kubuda. Imwe yeanonyanya kushanda matekinoroji ekutakura zvinwiwa zvecryogenic ndeye vacuum insulated pombi. Pazasi, tichaongorora kuti masisitimu aya anoshanda sei uye nei akakosha pakutakura zvakachengeteka zvinwiwa zvecryogenic.

Dambudziko rekutakura Cryogenic Liquids

Cryogenic liquids inochengetwa uye inotakurwa patembiricha iri pasi -150°C (-238°F). Pakutonhora kwakadzika kudaro, dzinowanzoita kuputika nekukasira kana dzakasangana nemamiriro ekunze. Dambudziko guru ndere kuderedza kupisa kwekushisa kuchengetedza zvinhu izvi zviri mumhepo yazvo panguva yekufambisa. Chero kuwedzera kwekushisa kunogona kukonzera kukurumidza vaporization, zvichikonzera kurasikirwa kwechigadzirwa uye njodzi dzinogona kuitika.

Vacuum Insulated Pipeline: Kiyi yekufambisa Kwakanaka

Vacuum insulated mapaipi(VIPs) mhinduro yakakosha yekutakura zvinwiwa zve cryogenic pamusoro pemadaro marefu uchideredza kupisa. Mapaipi aya ane mitsetse miviri: pombi yemukati, inotakura mvura inonzi cryogenic, uye pombi yekunze inovhara pombi yemukati. Pakati pezvikamu zviviri izvi pane vacuum, iyo inoshanda sechivharo chinodzivirira kuderedza kupisa kwekupisa uye mwaranzi. Thevacuum insulated pombitekinoroji inoderedza zvakanyanya kurasikirwa kwekupisa, kuve nechokwadi chekuti mvura inoramba iri patembiricha inodiwa mukati merwendo rwayo.

Kushandisa muLNG Transportation

Liquefied natural gas (LNG) imafuta ane mukurumbira uye anofanirwa kutakurwa patembiricha yakadzika se -162°C (-260°F).Vacuum insulated mapaipianoshandiswa zvakanyanya muzvivakwa zveLNG uye zviteshi zvekufambisa LNG kubva kumatangi ekuchengetera kuenda kuzvikepe kana zvimwe zvinotakura. Iko kushandiswa kweVIP kunovimbisa kushoma kupisa ingress, kuderedza boil-off gasi (BOG) kuumbwa uye kuchengetedza iyo LNG munzvimbo yayo ine liquefied panguva yekurodha uye kuburitsa mabasa.

Liquid Hydrogen uye Liquid Nitrogen Transportation

Saizvozvowo,vacuum insulated mapaipiakakosha mukufambisa kwemvura hydrogen (LH2) uye mvura nitrogen (LN2). Semuenzaniso, hydrogen yemvura inowanzoshandiswa mukutsvagisa nzvimbo uye tekinoroji yesero. Kudzikira kwayo kwakadzikira kwe -253°C (-423°F) kunoda masisitimu ekufambisa. VIPs inopa mhinduro yakanaka, inobvumira kufamba kwakachengeteka uye kwakanaka kweLH2 pasina kurasikirwa kukuru nekuda kwekupisa kwekushisa. Liquid nitrogen, inoshandiswa zvakanyanya mukurapa uye mumaindasitiri kunyorera, zvakare inobatsira kubva kuVIPs, kuve nechokwadi chekushisa kwayo kwakadzikama mukati mekuita.

Mhedziso: Basa reVacuum Insulated Pipelines muRamangwana reCryogenics

Sezvo maindasitiri achiramba achivimba necryogenic zvinwiwa, vacuum insulated mapaipiichaita basa rinowedzera rinokosha mukuona kuti kutakura kwavo kwakachengeteka uye kwakanaka. Nekugona kwavo kudzikisa kupisa kupisa, kudzivirira kurasikirwa kwechigadzirwa, uye kuwedzera kuchengetedzwa, VIPs chinhu chakakosha muchikamu chiri kukura cryogenic. Kubva kuLNG kuenda kumvura yehydrogen, tekinoroji iyi inovimbisa kuti zvinwiwa zvinodzikira-tembiricha zvinogona kutakurwa zviine kushomeka kwemamiriro ekunze uye kugona kwakanyanya.
