Hauv lub ntiaj teb loj heev ntawm kev tsim khoom lag luam, ntau qhov txuas tseem ceeb tsis tuaj yeem ua yam tsis muaj kev txhawb nqa ntawm cov ntaub ntawv ua tau zoo. Niaj hnub no, peb yuav qhia txog cov khoom siv uas ua lub luag haujlwm tseem ceeb hauv kev lag luam ib txwm muaj xws li lub cub tawg thiab cov txheej txheem desulfurization -Cov tshuaj tiv thaiv sintered silicon carbide ceramics.
Dab tsi yog silicon carbide ceramic?
Silicon carbide ceramic yog cov khoom siv ceramic siab heev uas muaj silicon thiab carbon. Nws tsis yog cov ceramic ib txwm muaj, tab sis yog "metamaterial" uas muaj ntau yam zoo heev. Nws muaj cov yam ntxwv ntawm lub zog kub siab, tiv taus kev hnav zoo, coefficient qis ntawm thermal nthuav dav, hardness siab, thiab tshuaj tiv thaiv corrosion, uas ua rau nws sawv tawm ntawm ntau cov ntaub ntawv.
Cov khoom siv sintered silicon carbide ceramics yog ib hom tshwj xeeb ntawm silicon carbide ceramics, thiab lawv cov txheej txheem npaj yog qhov tshwj xeeb heev - ua ntej, cov khoom me me ntawm alpha SiC thiab cov khoom ntxiv raug nias rau hauv lub cev ntsuab, thiab tom qab ntawd kov nrog kua silicon ntawm qhov kub siab. Thaum lub sijhawm no, cov pa roj carbon hauv qhov khoob dhau los ua qhov tshuaj lom neeg zoo kawg nkaus nrog cov Si nkag mus, tsim β - SiC thiab sib txuas nrog α - SiC. Tib lub sijhawm, silicon dawb puv cov qhov hws, thaum kawg tau txais cov khoom siv ceramic ntom ntom.
Lub pob zeb hauv lub qhov cub
Kev sib xyaw ua ke ntawm silicon carbide ceramics yog qhov tseem ceeb thiab tseem ceeb hauv ntau lub qhov cub kub siab. Piv txwv li, hauv cov qhov cub tsim cov khoom siv ceramic xws li cov kilns roller, cov kilns tunnel, cov kilns shuttle, thiab lwm yam, nws tau ua rau hauv cov khoom tseem ceeb xws li cov tes tsho nozzle, cov menyuam crossbeam, thiab cov kav dej txias.
Lub tes tsho nplaim taws nozzle tuaj yeem tswj tau qhov kub thiab txias hauv lub qhov cub kom zoo. Nws muaj cov yam ntxwv ntawm lub zog kub, tiv taus oxidation, tiv taus hnav, thiab tiv taus txias thiab cua sov sai. Nws yuav tsis tawg lossis deform tom qab siv qhov kub thiab txias ntev, ua kom muaj qhov kub thiab txias ruaj khov hauv lub qhov cub. Nws yog qhov tseem ceeb rau kev hlawv cov khoom siv ceramic zoo.
Cov crossbeam rollers thiab cov kav dej cua txias feem ntau muaj lub luag haujlwm tseem ceeb rau kev txhawb nqa thiab cua nkag. Cov crossbeam roller muaj cov yam ntxwv ntawm kev ruaj khov thermal zoo, tiv taus oxidation, thiab tiv taus kub siab. Nws tsis yooj yim rau deform thiab khoov tom qab siv ntev ntawm qhov kub siab, ua kom ntseeg tau tias qhov ruaj khov ntawm cov qauv sab hauv ntawm lub kiln thiab kev thauj khoom du. Cov kav dej cua txias yog lub luag haujlwm rau kev tswj hwm cov roj ntws thiab qhov kub thiab txias hauv lub kiln, ua kom ntseeg tau tias lub kiln ua haujlwm ib txwm.
Los ntawm qhov kev xav ntawm cov khoom siv kho kom haum, cov tshuaj tiv thaiv sintered silicon carbide muaj qhov zoo pom tseeb hauv kev tsim cov khoom siv hauv qhov cub. Vim nws qhov loj me yuav luag tsis hloov pauv ua ntej thiab tom qab sintering, nws tuaj yeem ua tiav rau hauv txhua yam duab thiab qhov loj me tom qab molding. Cov chaw tsim khoom hauv qhov cub tuaj yeem kho ntau yam duab thiab cov lus qhia ntawm cov khoom raws li cov qauv tsim qhov cub sib txawv thiab cov kev xav tau ntau lawm, ua tau raws li cov kev xav tau ntau lawm ntawm cov khoom loj thiab cov khoom sib txawv, uas nyuaj rau lwm cov ntaub ntawv ua tiav.
Txoj kab tiv thaiv ruaj khov ntawm desulfurization system
Hauv kev tiv thaiv ib puag ncig xws li lub chaw tsim hluav taws xob desulfurization, cov khoom siv silicon carbide ceramics uas tau ua sintered kuj ua lub luag haujlwm tseem ceeb, feem ntau yog pom hauv cov khoom tseem ceeb ntawm desulfurization nozzles. Cov pa roj flue uas tawm los ntawm cov chaw tsim hluav taws xob muaj ntau cov pa phem xws li sulfur dioxide, thiab desulfurization nozzles yog cov cuab yeej tseem ceeb rau kev tshem tawm cov pa phem no.
Lub nozzle desulfurization uas tau sintered silicon carbide muaj cov yam ntxwv zoo heev xws li muaj zog heev, tawv heev, tiv taus corrosion zoo heev, tiv taus hnav, thiab tiv taus kub heev. Nws muaj lub neej ua haujlwm zoo kawg nkaus nyob rau hauv cov xwm txheej hnyav, uas tsis muaj qhov sib piv rau cov ntaub ntawv ib txwm muaj. Cov hom desulfurization nozzles feem ntau siv suav nrog cov nozzles kauv thiab cov nozzles vortex, uas muaj cov qauv tsim thiab cov ntsiab cai ua haujlwm sib txawv, tab sis tuaj yeem ua rau lub desulfurizer atomize tau zoo thiab kov nws tag nrho nrog cov pa roj flue, yog li ua tiav cov txiaj ntsig desulfurization zoo.
Los ntawm kev tsim qauv tshwj xeeb, lub qhov cua ntswj ua rau cov kua hauv txheej sab nraud ntaus rau ntawm qhov cua ntswj ntawm lub kaum sab xis ntawm lub qhov cua ntswj, hloov qhov kev taw qhia txau thiab tawm hauv lub qhov cua ntswj, tsim cov khoom siv conical pos huab khov kho, uas tuaj yeem muab ntau yam lub kaum sab xis txau, thiab tseem muaj kev nqus dej zoo nyob rau hauv qhov siab qis tshaj plaws. Lub qhov cua ntswj tso cai rau cov kua nplaum nkag mus rau hauv lub qhov cua ntswj ntawm lub qhov cua ntswj los ntawm qhov kev taw qhia tangent, thiab tom qab ntawd tawm ntawm lub qhov ntawm cov ces kaum sab xis mus rau qhov kev taw qhia nkag. Cov tshuaj tsuag yog me me thiab sib xws, thiab cov channel vortex loj, uas tsis yooj yim rau thaiv.
Rau cov khoom siv kho kom haum ntawm cov tshuab desulfurization, cov tshuaj tiv thaiv sintered silicon carbide tuaj yeem kho cov duab nozzle tsim nyog tshaj plaws, qhov loj me, thiab cov yam ntxwv tsuag raws li cov txheej txheem desulfurization sib txawv, cov nqi roj flue, cov concentration, thiab lwm yam tsis, kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov ntawm lub tshuab desulfurization thiab ua tau raws li cov kev cai ib puag ncig uas nruj dua.
Cov khoom siv ua los ntawm silicon carbide uas tau sintered ua lub luag haujlwm tseem ceeb hauv cov teb kev lag luam ib txwm muaj xws li lub cub tawg thiab cov tshuab desulfurization vim lawv cov yam ntxwv tshwj xeeb thiab cov txiaj ntsig hloov kho tau. Lawv muab kev lees paub zoo rau kev ua haujlwm zoo, ruaj khov, thiab ib puag ncig zoo ntawm kev tsim khoom lag luam thiab txhaj tshuaj muaj zog rau hauv kev txhim kho thev naus laus zis thiab kev txhim kho ntawm cov lag luam ib txwm muaj.
