Intshayelelo

Izinto ezibangela ukurhawuzelelwa kwamanzi ezifana ne-nitrogen engamanzi (LN₂), i-oxygen engamanzi (LOX), i-argon engamanzi (LAr), igesi yendalo enyibilikisiweyo (LNG), kunye ne-hydrogen engamanzi (LH₂) zidlala indima ebalulekileyo kumashishini aqala kwimveliso yegesi yemizi-mveliso kunye ne-biotechnology ukuya kwimveliso ye-semiconductor, i-aerospace, kunye namandla acocekileyo.

Umngeni oqhelekileyo kuzo zonke ezi zicelo kukugcina amaqondo obushushu aphantsi kakhulu ngexesha lokudluliselwa. Ngaphandle kobushushu obaneleyo, ubushushu obuvela kwindawo engqongileyo bungena ngokukhawuleza kwinkqubo, nto leyo ebangela ukulahleka kwemveliso ngokuphefumla kunye nokunciphisa ukusebenza kakuhle kwenkqubo iyonke.

Ukujongana nale ngxaki, uninzi lwezixhobo zanamhlanje ezisebenzisa i-cryogenic zixhomekeke kwiipayipi ezifakwe i-vacuum insulation (VIPs), ezaziwa ngokuba ziipayipi ezifakwe i-vacuum jacketed. Ezi nkqubo zenzelwe ngokukodwa ukunciphisa ukungena kobushushu nokuqinisekisa ukudluliselwa okusebenzayo nokuthembekileyo kwezinto ezifakwa i-cryogenic.

Kutheni iCryogenic Liquid Transfer ifuna iipayipi ezikhethekileyo

Izinto ezimanzi ezibizwa ngokuba yi-cryogenic zigcinwa kumaqondo obushushu angaphantsi kakhulu kweemeko ezingqongileyo:

Ngenxa yokuba umahluko wobushushu phakathi kolwelo nokusingqongileyo udla ngokudlula ama-200°C, ubushushu ngokwemvelo bungena kwinkqubo yokudlulisa. Nokuba kuncinci kangakanani ukungena kobushushu kunokubangela ukuba inxalenye yolwelo ibe ngumphunga.

Oku kunokubangela oku:

• Ukwanda kwegesi yokubilisa (BOG)
• Ukulahleka kwemveliso
• Ukutshintshatshintsha koxinzelelo
• Iimeko zokuhamba kwamanzi ezinamanqanaba amabini

• Iindleko zokusebenza eziphezulu

Kwizicelo ezifuna ukuhanjiswa kolwelo okuzinzileyo, ubushushu obusebenzayo bubalulekile.

Indlela Iipayipi Ezifakwe I-Vacuum Insulated Ezisebenza Ngayo

Umbhobho ogqunywe nge-vacuum unemibhobho emibini yentsimbi engagqwaliyo engqindilili.

Umbhobho wangaphakathi uthwala ulwelo oluyi-cryogenic, ngelixa umbhobho wangaphandle wenza ijakethi yokukhusela. Phakathi kwemibhobho emibini kukho indawo ephezulu engenamanzi esebenza njengomqobo osebenzayo wobushushu.

Uninzi lweenkqubo ezisebenza kakuhle zikwabandakanya i-multilayer insulation (MLI) ngaphakathi kwendawo ye-vacuum. Xa zidibene, i-vacuum kunye ne-MLI zinciphisa kakhulu zonke iintlobo zokudluliselwa kobushushu, kubandakanya ukuhanjiswa kobushushu, i-convection, kunye ne-radiation.

Xa kuthelekiswa nemibhobho eqhelekileyo efakwe i-foam, imibhobho efakelwe i-vacuum insulation inciphisa kakhulu ukuvuza kobushushu, inceda ukugcina ulwelo olucryogenic luzinzile kulo lonke uhambo.

Uthutho lwe-LNG olusebenzisa iipayipi ezifakwe i-vacuum insulation

Igesi yendalo enyibilikisiweyo (i-LNG) idla ngokugcinwa kwaye ithuthwe malunga ne--162°C. Ukugcina obu bushushu kubalulekile ekunciphiseni ukuveliswa kwegesi ebilayo nokuqinisekisa ukusebenza kakuhle.
