Nyob rau hauv lub ntiaj teb loj ntawm kev lag luam ntau lawm, 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 kilns thiab desulfurization systems -Cov tshuaj tiv thaiv sintered silicon carbide ceramics.
Dab tsi yog silicon carbide ceramic?
Silicon carbide ceramic yog cov khoom siv ceramic zoo tshaj plaws ntawm silicon thiab carbon. Nws tsis yog ib qho yooj yim ceramic, tab sis "metamaterial" nrog ntau yam khoom zoo heev. Nws muaj cov yam ntxwv ntawm qhov kub thiab txias, zoo hnav tsis kam, coefficient ntawm thermal expansion, siab hardness, thiab tshuaj corrosion kuj, uas ua rau nws sawv tawm ntawm ntau cov ntaub ntawv.
Cov tshuaj tiv thaiv sintered silicon carbide ceramics yog ib hom tshwj xeeb ntawm silicon carbide ceramics, thiab lawv cov txheej txheem kev npaj yog qhov tshwj xeeb - ua ntej, cov khoom zoo ntawm alpha SiC thiab cov khoom ntxiv raug nias rau hauv lub cev ntsuab, thiab tom qab ntawd tiv tauj nrog cov kua silicon ntawm qhov kub thiab txias. Nyob rau lub sijhawm no, cov pa roj carbon monoxide hauv qhov khoob tau dhau los ua cov tshuaj tiv thaiv zoo heev nrog cov infiltrated Si, tsim β - SiC thiab sib txuas nrog α - SiC. Nyob rau tib lub sijhawm, silicon dawb puv lub qhov hws, thaum kawg tau txais cov khoom siv ceramic uas ntom ntom.
Lub hauv paus pob zeb hauv qhov cub
Cov tshuaj tiv thaiv sintering ntawm silicon carbide ceramics yog qhov tseem ceeb thiab lub luag haujlwm tseem ceeb hauv ntau qhov kub-kub kilns. Piv txwv li, nyob rau hauv ceramic ntau lawm kilns xws li cov menyuam kilns, tunnel kilns, shuttle kilns, thiab lwm yam., nws yog tsim rau hauv cov khoom tseem ceeb xws li nozzle tes tsho, crossbeam rollers, thiab cua txias kav.
Lub tes tsho nplaim taws tuaj yeem tswj tau qhov kub thiab txias hauv qhov cub. Nws muaj cov yam ntxwv ntawm qhov kub thiab txias lub zog, oxidation tsis kam, hnav tsis kam, thiab tsis kam ua kom txias thiab cua sov. Nws yuav tsis tawg lossis deform tom qab siv lub sijhawm ntev kub, kom ntseeg tau qhov kub thiab txias ib puag ncig hauv qhov cub. Nws yog ib qho tseem ceeb rau kev tua cov khoom siv hluav taws xob zoo.
Lub crossbeam rollers thiab cov cua txias ducts feem ua lub luag haujlwm tseem ceeb rau kev txhawb nqa thiab qhov cua. Lub crossbeam roller muaj cov yam ntxwv zoo thermal stability, oxidation tsis kam, thiab high-temperature creep resistance. Nws tsis yooj yim rau deform thiab khoov tom qab siv lub sijhawm ntev ntawm qhov kub thiab txias, ua kom muaj kev ruaj ntseg ntawm cov qauv sab hauv ntawm lub kiln thiab cov khoom siv thauj khoom zoo. Lub tshuab cua txias yog lub luag haujlwm rau kev tswj cov roj ntws thiab qhov kub thiab txias hauv qhov cub, kom ntseeg tau tias lub tshuab ua haujlwm li qub.
Los ntawm qhov kev xav ntawm cov khoom siv kho mob, cov tshuaj tiv thaiv sintered silicon carbide muaj qhov pom tseeb zoo hauv kev tsim cov khoom siv hluav taws xob. Vim nws yuav luag tsis hloov qhov loj me ua ntej thiab tom qab sintering, nws tuaj yeem ua tiav rau hauv ib qho duab thiab loj tom qab molding. Cov tuam txhab tsim hluav taws xob tuaj yeem hloov kho ntau yam duab thiab cov lus qhia tshwj xeeb ntawm cov khoom sib txawv raws li qhov sib txawv ntawm qhov cub tsim thiab cov kev xav tau ntau lawm, ua tau raws li qhov yuav tsum tau ua ntawm cov khoom loj thiab cov khoom zoo li qub, uas nyuaj rau lwm cov ntaub ntawv kom ua tiav.
Muaj zog tiv thaiv kab ntawm desulfurization system
Hauv kev tiv thaiv ib puag ncig xws li fais fab nroj tsuag desulfurization, cov tshuaj tiv thaiv sintered silicon carbide ceramics kuj ua lub luag haujlwm tseem ceeb, feem ntau yog xav txog hauv cov khoom tseem ceeb ntawm desulfurization nozzles. Cov pa hluav taws xob 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 tshem tawm cov pa phem no.
Cov tshuaj tiv thaiv sintered silicon carbide desulfurization nozzle muaj cov khoom zoo xws li lub zog siab, siab hardness, muaj zog corrosion kuj, hnav tsis kam, thiab kub tsis kam. Nws muaj lub neej ua haujlwm txawv tshaj plaw nyob rau hauv cov xwm txheej hnyav, uas yog qhov sib piv rau cov khoom siv zoo tib yam. Feem ntau siv hom desulfurization nozzles muaj xws li kauv nozzles thiab vortex nozzles, uas muaj cov qauv sib txawv thiab cov qauv kev ua haujlwm, tab sis tuaj yeem ua kom zoo atomize lub desulfurizer thiab tag nrho nws nrog cov roj flue, yog li ua tiav cov txiaj ntsig zoo desulfurization.
Los ntawm cov qauv tsim tshwj xeeb, cov kauv nozzle ua rau cov kua hauv txheej txheej ntaus cov kauv nto ntawm ib lub kaum sab xis ntawm lub nozzle, hloov cov kev taw qhia txau thiab tawm ntawm lub nozzle, tsim cov khoom conical pos huab teb, uas tuaj yeem muab ntau hom tshuaj tsuag cov ces kaum, thiab tseem muaj kev nqus tau zoo nyob rau hauv qhov qis tshaj. Lub vortex nozzle tso cai rau slurry nkag mus rau hauv lub swirl chamber ntawm lub nozzle los ntawm tangent kev taw qhia, thiab ces eject los ntawm lub orifice ntawm txoj cai kaum mus rau inlet kev taw qhia. Cov tshuaj tsuag yog me me thiab sib xws, thiab cov vortex channel loj, uas tsis yooj yim los thaiv.
Rau kev kho qhov chaw ntawm desulfurization systems, cov tshuaj tiv thaiv sintered silicon carbide tuaj yeem kho qhov zoo tshaj plaws nozzle zoo, qhov loj, thiab cov yam ntxwv tshuaj tsuag raws li cov txheej txheem desulfurization sib txawv, flue gas flow rates, concentrations, and other parameters, assuring efficiency and stability of the desulfurization system thiab ntsib cov kev xav tau ntawm ib puag ncig.
Cov tshuaj tiv thaiv sintered silicon carbide ceramics ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev lag luam ib txwm muaj xws li kilns thiab desulfurization systems vim lawv cov khoom tshwj xeeb thiab cov txiaj ntsig zoo. Lawv muab kev lav phib xaub rau kev ua haujlwm zoo, ruaj khov, thiab ib puag ncig tus phooj ywg ntawm kev tsim khoom lag luam thiab txhaj tshuaj muaj zog rau hauv kev hloov kho thev naus laus zis thiab kev txhim kho ntawm kev lag luam ib txwm muaj.
