Uthotho lweVTN HTN oluMiselweyo lweeTanki zoGcino lweLNG
I-BTCE VTN okanye i-HTN iitanki zokugcina ze-LNG ze-LNG ziyilelwe i-LNG (i-Liquefied Natural Gas), ezithe nkqo (VTN) okanye ezithe tye (HTN) zokugcina itanki ene-vacuum perlite okanye i-super insulation. Amatanki akhoyo anamandla ukusuka kwi-5 m³ ukuya kwi-100m³ kunye noxinzelelo oluphezulu oluvumelekileyo lokusebenza ukusuka kwi-8 ukuya kwi-bar ye-17 kwaye yenzelwe ngokwekhowudi yaseTshayina, i-AD2000-Merkblatt, ikhowudi ye-EN, 97/23/EC PED (IsiXhobo soMyalelo), ikhowudi ye-ASME, e-Australia. /New Zealand AS1210 njl.
■ VTN /HTN LNG iitanki ze-cryogenic ziyilwe ngokuhambelana nazo zonke iimfuno ze-LNG ukuze zisebenze ngokukhuselekileyo, kulula kunye noqoqosho. Uninzi lweempawu zibandakanyiwe ngokusondeleyo.
■ Ukwamkelwa kweteknoloji yokomeleza ubunzima, ukonga i-30% ye-stainless
■ Uyilo lolwakhiwo lwenkxaso yokhuselo lobunikazi, ukunciphisa ukuhanjiswa kobushushu ukunciphisa isantya somphunga wemihla ngemihla, kwaye unokumelana nomthwalo onzima wenyikima, uphumelele ipatent yesizwe (ilungelo elilodwa lomenzi wechiza Inani: ZL200820107912.9);
■ Isingxobo sangaphandle senziwe ngentsimbi yekhabhoni, kwaye iindawo ekulula ukuyonakalisa ipeyinti ekuphakamiseni, ukuthutha kunye nokusebenza zikhuselwe ngezinto zensimbi ezingenasici ukuqinisekisa ubomi benkonzo kunye nobuhle bepeyinti;
∎ Zonke iipleyiti zemibhobho zenziwe ngentsimbi engatyiwayo, enokuthi ithintele iqokobhe lombhobho lokukhenkceza kwiqondo eliphantsi lokuqhekeka kwe-brittle kwaye lonakalise ipeyinti ngexesha lokusetyenziswa.
■ Ukuzaliswa kweperlite ephuculweyo kunye nenkqubo yokugquma imathiriyeli ukuqinisekisa isiphumo esingcono sokugquma umaleko wokugquma;
■ Isixokelelwano sokusebenza sevalvu sixinene kwaye kulula ukuyisebenzisa nokuyigcina;
■ Iivalvu ezidityaniswe nevacuum zonke ngamalungu angeniswa kumazwe angaphandle ukuqinisekisa ubomi bevacuum nokuthembeka;
∎ Umphandle wetanki ugalelwe isanti kwaye utshizwe ngepeyinti yeHEMPEL emhlophe ye-epoxy ubomi obude kunye nobuhle, ukunciphisa ukuhanjiswa kobushushu bemitha kunye nokuncitshiswa kokuphuma komphunga mihla le.

IBeijing Tianhai Cryogenic Equipment Co., Ltd. yeyokuqala itanki yokugcina i-LNG eTshayina, kwaye inentsebenziswano esondeleyo neyona mveliso inkulu yehlabathi ye-LNG ehlanganisiweyo yezixhobo, iHoupu Clean Energy Co., Ltd. kunye neChongqing Naide Energy Equipment Integration Co., LTD. . Izixhobo zethu zisetyenziswa kakhulu kwiinkampani ezinkulu zamandla asekhaya, ezifana ne-PETROCHINA, iSinopec, i-China Gas, njl., zilandelwa ngabahlanganisi ukwandisa ishishini langaphandle, iimveliso zethu zisetyenziswa kwi-European Union, kumazwe akuMzantsi-mpuma we-Asia.
Iingenelo zokusebenzisa iimveliso ze-LNG zenkampani yethu ziquka:
1. Ukuvelisa i-pearlite yomgangatho ophezulu ngokwethu. Ukuze kuqinisekiswe ukuba itanki yokugcina inelona nqanaba liphezulu lesiphumo sokufakelwa kwe-thermal, izinto ezingundoqo zokuzalisa kwi-vacuum layer yesanti yokugcina itanki yepearlized iyaziveliswa kwaye ibonelelwe, kwaye isithando somlilo sobuchwephesha singeniswa eMelika. Kujikelezo lweemarike, ixabiso le-pearlite lidla ngokubalwa ngokomthamo. Ukuze ufumane inzuzo ephezulu, abanye abavelisi be-pearlite bandisa i-pearlite ukuya phezulu, okubangelwa ukuhla okubukhali ekusebenzeni kwe-insulation ye-pearlite. Inkampani yethu isebenzisa izixhobo zobuchwephesha kunye netekhnoloji yepearlite yasekhaya, ilawula ngokungqongqo umyinge wokwandiswa kwepearlite, ukuqinisekisa olona mlinganiso wokwandiswa kwepearlite kunye nesiphumo sesicelo. Ukusuka kwingcambu yokuqinisekisa ukusebenza kakuhle kunye nozinzo lokugqunyelelwa kwe-thermal kwitanki yokugcina yenkampani yethu, isantya somphunga wemihla ngemihla sisezantsi kakhulu kuneemfuno zomgangatho wesizwe (ungaphantsi kwe-0.2%) zokusebenzisa kunye nokufumana inzuzo yezoqoqosho engcono.
2. Ulwakhiwo lwenkxaso phakathi kwezikhongozeli zangaphakathi nezangaphandle ezinobuchwepheshe obunelungelo elilodwa lomenzi wechiza. Iskimu senkxaso phakathi kwangaphakathi nangaphandle kwetanki yokugcina kwakhona iteknoloji yethu enelungelo lobunikazi. Ngokusebenzisa inkxaso yesakhiwo esikhethekileyo sesinyithi esineempawu zeflethi, ezimxinwa kunye nezide, umphumo wokushisa ubushushu phakathi kwezikhongozeli zangaphakathi nangaphandle ziyancipha kakuhle, kwaye nazo zineempawu zenkxaso ezinzileyo kunye nobomi obude bokukhathala kwesinyithi.
3. Ipeyinti yeHEMPEL engeniswe eDenmark. Umgangatho wepeyinti yomphezulu wetanki ubalasele kwaye ngenkqubo yokupeyinta ephucukileyo ukuqinisekisa umphezulu wetanki ogudileyo. Iitanki zokugcina zinokuqina, zingenambala kunye nokukhanya okuphezulu ekukhanyeni. Ngowona mgangatho ubalaseleyo wepeyinti kunye nowona msebenzi ubalaseleyo wokuqinisekisa ukuncitshiswa okukhulu kwemitha yobushushu bangaphandle kwitanki.
4. Uyilo lwemibhobho ephuculweyo kunye noyilo. Uyilo lwesakhiwo sombhobho wokungena kunye nowokuphuma lufanelekile kwaye luvavanyelwe ukusetyenziswa kwexesha elide, olunciphisa kakhulu ukuveliswa kwe-electrostatic kwinkqubo yokubuyisela ulwelo lwe-LNG. Kwaye kwinkqubo yokungenisa ulwelo, inokudlala indima yokupholisa kunye nokunciphisa uxinzelelo kwindawo yegesi yesigaba sokugcina itanki. Inciphisa kakhulu ukumelana nokuhamba ngexesha lokutsalwa kwamanzi kwaye igweme ukubunjwa kwe-whirlpool yamanzi ngexesha lokutsalwa ngokukhawuleza kwamanzi. Uyilo olufanelekileyo lwe-outlet, zithintele iindawo zokuphuma ezimbini ngaxeshanye xa isenzeko sokuphambuka kolwelo.
