"Woteteza Wolimba Mtima" wa Kuyeretsa Mpweya wa Flue: Nchifukwa chiyani Nozzle ya Silicon Carbide Desulfurization Irreplaceable?

Mu ndondomeko yaikulu yochizira mpweya wa flue wa mafakitale, nozzle yochotsa sulfur ndi gawo lofunika kwambiri lomwe limagwiritsa ntchito mphamvu zake mwakachetechete - limagwira ntchito ngati mutu wopopera womwe umachita "kuyeretsa mozama" mpweya wa flue, ndikupangitsa kuti slurry yochotsa sulfurization ikhale madontho ang'onoang'ono omwe amachitapo kanthu mokwanira ndi zinthu zoipitsa monga sulfur dioxide, motero kuteteza mpweya wabwino. Pakati pa zipangizo zosiyanasiyana zochotsera sulfur,kabide ya silikoni, ndi ubwino wake wapadera, yakhala chisankho chokondedwa kwambiri m'mafakitale, ikugwira ntchito ngati "woteteza wolimba" weniweni m'makina ochotsera sulfur.
Anthu ambiri angakhale ndi chidwi chofuna kudziwa chifukwa chake silicon carbide imasankhidwa mwapadera. Izi zitha kutsatiridwa ndi malo ovuta a ntchito yochotsa sulfur. Mpweya wa flue wa mafakitale sumangokhala ndi mankhwala ambiri owononga kwambiri, komanso tinthu ta fumbi tomwe timayenda mwachangu. Nthawi yomweyo, malo ogwirira ntchito amakumana ndi kusinthasintha kwakukulu kwa kutentha, zomwe zimapangitsa kuti zikhale zovuta kuti zipangizo wamba zipirire. Ma nozzles achitsulo amatha kuwononga ndi dzimbiri, pomwe zoumba wamba sizingathe kupirira kuwonongeka kwa tinthu tating'onoting'ono ndipo posachedwa zidzawonongeka ndi kusweka, zomwe zimakhudza zotsatira za kuchotsa sulfur.

Mbali yodabwitsa ya silicon carbide ili mu kuthekera kwake kuthana ndi mavutowa mosavuta. Monga chida cha ceramic chomwe chimagwira ntchito bwino kwambiri, kuuma kwake ndi kwachiwiri kuposa diamondi. Ikakumana ndi fumbi lothamanga kwambiri, imagwira ntchito ngati kuvala "zida" zosanjikiza, ndi kukana kuwonongeka kopitilira kwa zitsulo ndi zoumba wamba. Kapangidwe kake ka mankhwala ndi kokhazikika kwambiri, kusunga umphumphu wa kapangidwe kake m'malo amphamvu a asidi ndi alkali popanda dzimbiri kapena kuwonongeka. Ndi kukana kochepa, imatha kupanga madontho ofanana komanso abwinobwino, kukulitsa malo olumikizirana pakati pa zodetsa ndi matope, motero kumawonjezera mphamvu ya desulfurization. Kuphatikiza apo, pamwamba pake posalala sipangakhale kukula ndi kutsekeka, zomwe zimapangitsa kukonza pambuyo pake kukhala kosavuta. Palibe chifukwa chogwiritsa ntchito nthawi yosinthira, kuchepetsa kwambiri ndalama zokonzera komanso kutayika kwa nthawi yogwira ntchito popanga mafakitale.
Masiku ano, m'mafakitale omwe amafuna kuchotsedwa kwa mpweya wofewa, monga kupanga mphamvu zamagetsi, zitsulo zachitsulo, ndi uinjiniya wa mankhwala, ma nozzles a silicon carbide desulfurization akhala chisankho chachikulu. Chifukwa cha ubwino wake wokana kuwonongeka, kukana dzimbiri, komanso kukana kutentha kwambiri, imatha kugwira ntchito mokhazikika kwa nthawi yayitali pansi pa mikhalidwe yovuta yogwirira ntchito, kuonetsetsa kuti njira yochotsera sulfurization ikugwira ntchito bwino, kuchepetsa ndalama zonse zamabizinesi, ndikulimbikitsa chitukuko chogwirizana cha kupanga mafakitale ndi kuteteza chilengedwe.
