Tsim thiab tsim cov cub tawg hydrogenation
Txheej txheem cej luam:
Lub cub tawg hydrogenation yog ib hom cub tawg tubular cua sov, uas ntxuav thiab ua kom cov roj nyoos los ntawm kev tshem tawm nws cov impurities, xws li sulfur, oxygen, thiab nitrogen, thiab saturating olefin thaum lub sijhawm hydrogenation, los ntawm kev tawg thiab isomerization reactions ntawm qhov siab dua (100-150Kg / Cm2) thiab kub (370-430 ℃). Raws li ntau hom roj nyoos refined, muaj diesel hydrogenation cub tawg, roj seem hydrodesulfurization cub tawg, roj av refining hydrogenation cub tawg thiab lwm yam.
Cov qauv ntawm lub cub tawg hydrogenation zoo ib yam li lub cub tawg tubular cua sov, hauv cov duab ntawm lub tog raj kheej lossis lub thawv. Txhua lub cub tawg yog tsim los ntawm lub chamber hluav taws xob thiab lub chamber convection. Lub cua sov hauv lub chamber radiant feem ntau yog hloov los ntawm kev hluav taws xob, thiab lub cua sov hauv lub chamber convection feem ntau yog hloov los ntawm convection. Raws li cov xwm txheej tshuaj tiv thaiv ntawm hydrogenation, cracking, thiab isomerization, lub cub tawg kub ntawm lub cub tawg hydrogenation yog li 900 ° C. Vim yog cov yam ntxwv saum toj no ntawm lub cub tawg hydrogenation, cov fiber lining feem ntau tsuas yog siv rau phab ntsa thiab sab saum toj ntawm lub chamber radiant. Lub chamber convection feem ntau yog cam khwb cia nrog refractory castable.

Cov seem seem siv CCEWOOL cov khoom siv ua los ntawm cov khoom siv ceramic fiber ntau ua cov khoom siv kub rau lub teeb ci, thiab cov ntaub ntawv sab nraub qaum rau cov khoom siv ceramic fiber thiab cov cib sib zog siv CCEWOOL tus qauv fiber pam.
Cov qauv hauv pem teb:
Raws li kev faib tawm ntawm cov burner nozzles hauv lub cub tawg hydrogenation, muaj ob hom qauv cub tawg: lub cub tawg cylindrical thiab lub thawv cub tawg, yog li muaj ob hom qauv.
Lub cub tawg cylindrical:
Raws li cov yam ntxwv ntawm lub cub tawg cylindrical, qhov cib sib zog ntawm hauv qab ntawm phab ntsa cub tawg ntawm lub chamber radiant yuav tsum tau tiled nrog CCEWOOL ceramic fiber pam, thiab tom qab ntawd stacked nrog CCEFIRE lub teeb refractory cib; cov seem seem tuaj yeem tiled nrog ob txheej ntawm CCEWOOL tus qauv ceramic fiber pam, thiab tom qab ntawd stacked nrog high-aluminium ceramic fiber Cheebtsam hauv cov qauv herringbone anchoring.
Sab saum toj ntawm lub cub tawg siv ob txheej ntawm CCEWOOL tus qauv ceramic fiber pam, thiab tom qab ntawd muab cov modules siab-aluminium tso rau hauv ib lub qhov dai anchor qauv nrog rau cov modules folding welded rau phab ntsa cub tawg thiab kho nrog cov ntsia hlau.
Lub thawv cub tawg:
Raws li cov yam ntxwv ntawm lub thawv cub tawg, qhov cib sib zog ntawm hauv qab ntawm phab ntsa cub tawg ntawm lub chamber radiant yuav tsum tau tiled nrog CCEWOOL ceramic fiber pam, thiab tom qab ntawd stacked nrog CCEFIRE lightweight refractory cib; tus so tuaj yeem tiled nrog ob txheej ntawm CCEWOOL tus qauv ceramic fiber pam, thiab tom qab ntawd stacked nrog high-aluminium fiber Cheebtsam hauv lub kaum sab xis hlau anchor qauv.
Sab saum toj ntawm lub cub tawg siv ob txheej vuas ntawm CCEWOOL tus qauv ceramic fiber pam vov uas muaj cov khoom siv ceramic fiber ntau ua los ntawm txhuas hauv ib lub qhov dai.
Ob hom qauv ntawm cov khoom siv fiber no ruaj khov heev hauv kev teeb tsa thiab kho, thiab kev tsim kho sai dua thiab yooj yim dua. Ntxiv mus, lawv yooj yim rau kev rhuav tshem thiab sib sau ua ke thaum lub sijhawm txij nkawm. Cov ntaub fiber muaj kev ruaj khov zoo, thiab kev ua haujlwm rwb thaiv tsev kub 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 phab ntsa cua sov siv cov khoom siv fiber "herringbone" lossis "angle iron", uas tau teeb tsa tib qho kev coj ua raws li kev coj ua folding. Cov ntaub pua plag fiber ntawm cov khoom siv tib yam ntawm cov kab sib txawv tau tais rau hauv daim duab U kom them rau cov fiber shrinkage.
Rau qhov chaw nruab nrab ntawm cov khoom siv fiber uas tau teeb tsa raws txoj kab nruab nrab mus rau ntug ntawm lub cub tawg cylindrical ntawm sab saum toj ntawm lub cub tawg, qhov kev npaj "parquet pem teb" tau txais yuav; cov blocks folding ntawm ntug yog kho los ntawm cov ntsia hlau welded rau ntawm phab ntsa cub tawg. Cov modules folding nthuav dav mus rau hauv qhov kev taw qhia mus rau phab ntsa cub tawg.
Cov khoom siv fiber ntau hauv nruab nrab ntawm sab saum toj ntawm lub thawv cua sov txais yuav kev npaj "parquet pem teb".
