Lub plhaub - Thiab {{1} {tease} Kev Kub Cua Kub Exchanger rau NaphHha Daim Ntawv Thov
Lub plhaub - Thiab - Lub raj cua kub ExchangerRau Naphtha Daim Ntawv Thov
Muaj lub plhaub plhaub ntawm lub plhaub -}} - Kev Kub Hluav Taws Xob, sab hauv uas muaj pob ntawm cov hlab. Thaum siv rau Naphha, ib qho kua dej (xws li naphtha) ntws los ntawm cov hlab, thiab lwm yam kua (xws li roj cua txias dua) ntws sab nraum lub plhaub hauv lub khauj khaum. Tshav kub yog pauv los ntawm qhov siab - kub kua rau qhov qis- Cov raj raj dej kub los ntawm kev ua kom sov thiab convection ntawm ob sab ntawm lub raj ntsa.
Cov Txheej Txheem Qauv Txheej Txheem: Nws tsuas yog tsim cov leeg ntawm cov raj, cov raj ntawm cov raj, pob tw, lub plhaub raj, ncu,}}} {2} raws li cov raj. The shell provides a flow space for the shell - side fluid, and the baffles can improve the flow state of the fluid, increase the heat - transfer area and enhance the heat - transfer effect.
Daim Ntawv Thov Kev Sau Npe nyob NaphHha Ua
Pre - cua sov thiab cua txias: nyob rau hauv naphtha cracking chav, tusLub plhaub - Thiab - Lub raj cua kub ExchangerYuav siv tau los ua ntej - naphtha ua kom nws txias cov tshuaj tawg kom yooj yim sib cais thiab kev ua haujlwm. Piv txwv li, kub lub naphthha los ntawm txog 25 qib mus rau 220℃ua ntej nkag mus rau reactor.
Kev kub ceev: Hauv Naphha Hydrogenation cov koog, muaj ntau ntau ntawm cov cua sov yog tso tawm thaum hydrogenation cov tshuaj tiv thaiv. Lub plhaub -} thiab-}}}} pa roj tov, thiab txhim kho lub zog siv hluav taws xob, thiab txhim kho cov khoom siv hluav taws xob.
Kev sib cais: nyob rau hauv cov txheej txheem distillation ntawm naphtha, lub plhaub {{} {{} Lub raj cua sov kom nws thiaj li ua kom pom kev sib cais ntawm cov khoom sib txawv ntawm cov boiling kis.
Cov khoom siv xaiv
Cov Khoom Siv Tube: Feem ntau, stainless hlau yog xaiv, xws li 304, 316L, thiab lwm yam tuaj yeem muaj qee cov tshuaj xeb, thiab cov hlau tsis muaj zog, muaj cov hlau tsis muaj zog. Hauv qee kis nrog kev yuav tsum tau qis dua, cov xaim hluav taws xob kuj tseem siv tau, tab sis anti {{4 4}} corrosion ntsuas yuav tsum tau coj.
Cov khoom siv plhaub: Cov hlau roj carbon hlau feem ntau siv, xws li q {}} Cov khaub ncaws ua haujlwm tau raug xaiv kom ntseeg tau lub zog thiab corrosion tsis kam ntawm cov khoom siv.
Qhov zoo hauv NaphHha Daim Ntawv Thov
Muaj kub -} Hloov cov txheej txheem, thiab lwm yam cua sov}
Muaj zog hloov tau: nws tuaj yeem hloov kho cov kev ua haujlwm sib txawv xws li kub siab, siab thiab muaj ntau yam kev xaiv. Nws tuaj yeem tsim thiab tsim tawm raws li cov txheej txheem tshwj xeeb ntawm naphHha ua.
Kev Tu Yooj Yim: Cov qauv yooj yim kuj yooj yim, thiab kev hloov pauv cov raj tuaj yeem ntxuav lossis kho kom yooj yim rau cov khoom siv niaj hnub thiab txhim kho kev ua haujlwm tau zoo.
