Tsim thiab Tsim Kho Cov Cracking furnaces
Txheej txheem cej luam:
Lub cub tawg yog cov khoom siv tseem ceeb rau kev tsim cov ethylene loj, uas siv cov roj hydrocarbons (ethane, propane, butane) thiab cov kua hydrocarbons (roj teeb, diesel, diesel nqus tsev) ua cov khoom siv raw. Lawv, ntawm lub sijhawmperantawm750-900, yogthermally tawg los tsim cov khoom siv raw petrochemical,xws li ethane, propane, butadiene, acetylene thiab aromatics. Muaj ob homlub cub tawg: lublub cub tawg diesel lub teeb thiablubethane tawg cub tawg, ob qho tib si yog hom cua sov ntsug. Lub qauv cua sov feem ntau muaj ob ntu: sab saud yog ntu convection, thiab sab hauv qab yog ntu radiant. Lub raj cua sov ntsug hauv ntu radiant yog qhov tshuaj tiv thaiv rau cov cua sov hydrocarbon ntawm cov khoom tawg. Lub cua sov kub yog 1260 ° C, thiab phab ntsa ntawm ob sab thiab hauv qab yog nruab nrog cov roj thiab roj hlawv. Vim yog cov yam ntxwv saum toj no ntawm lub cua sov tawg, cov fiber ntau tsuas yog siv rau phab ntsa thiab sab saum toj ntawm lub chamber radiant.
Kev txiav txim siab cov ntaub ntawv hauv ob sab:
Xav txog qhov siabqhov cub kub (feem ntau yog li 1260℃)thiabib qho chaw txo qis zognyob rau hauvlub cub tawgib yam li ntawdpeb cov xyoo ntawm kev tsim qauv thiab kev tsim kho thiabqhov tseeb tias ib qhontau qhov tawgFeem ntau cov cub tawg feem ntau muab faib rau hauv lub cub tawg ntawm qab thiab ob sab ntawm phab ntsa, cov khoom siv hauv pem teb ntawm lub cub tawg tau txiav txim siab suav nrog 4m siab lub teeb ci ntsa iab. Cov seem seem siv cov khoom siv fiber ntau zirconium ua cov khoom siv kub rau hauv pem teb, thaum cov ntaub ntawv hauv pem teb tom qab siv CCEWOOL siab txhuas (siab purity) ceramic fiber pam.
Cov qauv hauv pem teb:
Xav txog cov hluav taws kub ntau hauv lub cub tawg thiab cov yam ntxwv ntawm lub qhov cub cua sov hom ntsug hauv cov qauv thiab raws li peb ntau xyoo ntawm kev tsim qauv thiab kev tsim kho, lub qhov cub saum toj kawg nkaus siv cov qauv ntawm ob txheej ntawm CCEWOOL siab txhuas (lossis siab purity) ceramic fiber pam + qhov chaw nruab nrab hoisting fiber Cheebtsam. Cov khoom fiber tuaj yeem ntsia thiab kho kom ruaj khov rau hauv lub kaum sab xis hlau lossis plug-in fiber Cheebtsam qauv ntawm phab ntsa cub, thiab kev tsim kho yog ceev thiab yooj yim nrog rau disassemble thiab sib sau ua ke thaum lub sijhawm txij nkawm. Lub fiber lining muaj kev ncaj ncees zoo, thiab kev ua haujlwm rwb thaiv tsev kub yog qhov zoo kawg nkaus.
Daim ntawv ntawm kev teeb tsa fiber ntau hauv qab:
Raws li cov yam ntxwv ntawm cov qauv anchoring ntawm cov khoom siv fiber, cov khoom siv fiber hauv nruab nrab ntawm sab saum toj ntawm lub cub tawg txais yuav "parquet pem teb". Cov hlau kaum sab xis lossis cov khoom siv fiber ntsaws rau ntawm phab ntsa cub tawg tau teeb tsa tib qho kev coj ua raws li kev coj ua. Cov pam fiber ntawm cov khoom siv tib yam hauv cov kab sib txawv tau tais rau hauv daim duab U kom them rau cov fiber shrinkage.
