M'dziko lalikulu la mafakitale opanga mafakitale, maulalo ambiri ofunikira sangathe kuchita popanda kuthandizidwa ndi zipangizo zamakono. Lero, tikuwonetsa zinthu zomwe zimagwira ntchito yofunika kwambiri m'mafakitale azikhalidwe monga ma kilns ndi machitidwe a desulfurization -reaction sintered silicon carbide ceramics.
Kodi silicon carbide ceramic ndi chiyani?
Silicon carbide ceramic ndi zida zapamwamba za ceramic zopangidwa ndi silicon ndi kaboni. Si ceramic wamba, koma "metamaterial" yokhala ndi zinthu zambiri zabwino. Ili ndi mawonekedwe amphamvu yotentha kwambiri, kukana kwabwino kovala, kutsika kocheperako kwa kukulitsa kwamafuta, kuuma kwakukulu, komanso kukana kwa dzimbiri kwamankhwala, zomwe zimapangitsa kuti ziwonekere pakati pa zida zambiri.
Rection sintered silicon carbide ceramics ndi mtundu wapadera wa silicon carbide ceramics, ndipo ndondomeko yawo yokonzekera ndi yapadera kwambiri - choyamba, tinthu tating'ono ta alpha SiC ndi zowonjezera zimapanikizidwa mu thupi lobiriwira, ndiyeno zimagwirizanitsidwa ndi silicon yamadzimadzi pa kutentha kwakukulu. Panthawiyi, carbon yomwe ili yopanda kanthu imakhala ndi mankhwala odabwitsa kwambiri ndi Si, yomwe imapanga β - SiC ndikugwirizanitsa mwamphamvu ndi α - SiC. Nthawi yomweyo, silicon yaulere imadzaza ma pores, pamapeto pake imapeza zida za ceramic zowuma kwambiri.
Mwala wapangodya mu ng'anjo
Rection sintering of silicon carbide ceramics ndi gawo lofunikira komanso lofunikira pamawotchi osiyanasiyana otentha kwambiri. Mwachitsanzo, m'makina opangira zida za ceramic monga ng'anjo zodzigudubuza, zowotchera ngalande, zowotchera, ndi zina zambiri, amapangidwa kukhala zinthu zofunika kwambiri monga manja a nozzle, ma roller a crossbeam, ndi mapaipi a mpweya ozizira.
Bokosi lamoto wamoto limatha kuwongolera bwino kutentha mkati mwa ng'anjo. Ili ndi mawonekedwe amphamvu ya kutentha kwambiri, kukana kwa okosijeni, kukana kuvala, komanso kukana kuzizira kofulumira komanso kutentha. Sichidzathyoka kapena kupunduka pambuyo pogwiritsira ntchito kutentha kwakukulu kwa nthawi yaitali, kuonetsetsa kuti kutentha kumakhala kokhazikika mu uvuni. Ndikofunikira kuwombera zinthu za ceramic zapamwamba kwambiri.
Ma roller a crossbeam ndi ma ducts ozizira mpweya amanyamula udindo wofunikira pothandizira ndi mpweya wabwino. Wodzigudubuza wa crossbeam ali ndi mawonekedwe a kukhazikika kwamafuta abwino, kukana kwa okosijeni, komanso kukana kutentha kwambiri. Sikophweka kupunduka ndi kupindika pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali pa kutentha kwakukulu, kuonetsetsa kuti mkati mwa ng'anjo kukhazikika komanso kusuntha zinthu zosalala. Mpweya wozizira wozizira ndi womwe umayang'anira kayendedwe ka gasi ndi kugawa kutentha mkati mwa ng'anjo, kuonetsetsa kuti ng'anjoyo ikugwira ntchito bwino.
Kuchokera pamalingaliro a magawo osinthika, reaction sintered silicon carbide ili ndi zabwino zodziwikiratu popanga zida zamoto. Chifukwa cha kukula kwake kosasinthika isanayambe kapena itatha sintering, ikhoza kusinthidwa kukhala mawonekedwe ndi kukula kwake mutatha kuumba. Opanga ng'anjo amatha kusintha mawonekedwe osiyanasiyana ndi mafotokozedwe amitundu yosiyanasiyana malinga ndi mapangidwe ang'onoang'ono ndi zofunikira zopangira, kukwaniritsa zofunikira zopanga zinthu zazikulu komanso zovuta zowoneka bwino, zomwe zimakhala zovuta kuti zida zina zitheke.
Njira yodalirika yodzitetezera ya desulfurization system
M'munda wachitetezo cha chilengedwe monga desulfurization yamagetsi, zoumba za sintered silicon carbide zimagwiranso ntchito yofunika kwambiri, zomwe zikuwonetsedwa mu gawo lofunikira la nozzles desulfurization. Mpweya wotuluka m'mafakitale opangira magetsi uli ndi zowononga zambiri monga sulfure dioxide, ndipo ma nozzles a desulfurization ndi zida zofunika pakuchotsa zowononga izi.
Zomwe sintered silicon carbide desulfurization nozzle zili ndi zinthu zabwino kwambiri monga kulimba kwambiri, kuuma kwakukulu, kukana kwa dzimbiri, kukana kuvala, komanso kukana kutentha kwambiri. Ili ndi moyo wautumiki wodabwitsa pansi pazovuta, zomwe sizingafanane ndi zida wamba. Mitundu yomwe imagwiritsidwa ntchito kwambiri ya nozzles ya desulfurization imaphatikizapo ma spiral nozzles ndi vortex nozzles, omwe ali ndi mapangidwe osiyanasiyana ndi mfundo zogwirira ntchito, koma amatha kutulutsa bwino desulfurizer ndikulumikizana nayo ndi mpweya wa flue, potero amapeza zotsatira zabwino za desulfurization.
Kupyolera mu kapangidwe wapadera structural, ndi kozungulira nozzle amapanga madzi mu wosanjikiza akunja kugunda kozungulira pamwamba pa ngodya inayake pa nozzle, amasintha kupopera malangizo ndi kusiya nozzle, kupanga olimba conical chifunga munda, amene angapereke zosiyanasiyana ngodya kutsitsi, ndipo akadali mkulu mayamwidwe dzuwa pansi pa mavuto otsika kwambiri. Mphuno ya vortex imalola kuti slurry alowe m'chipinda chozungulira cha nozzle kuchokera kumbali ya tangent, ndiyeno atuluke kuchokera kumtunda kumakona abwino kupita kumalo olowera. Kupopera ndi kochepa komanso kofanana, ndipo njira ya vortex ndi yayikulu, yomwe siili yophweka kutsekereza.
Pakuti mbali makonda kachitidwe desulfurization, anachita sintered pakachitsulo carbide akhoza Mwamakonda Anu abwino kwambiri nozzle mawonekedwe, kukula, ndi makhalidwe utsi malinga ndi njira zosiyanasiyana desulfurization, flue mpweya otaya mitengo, ndende, ndi magawo ena, kuonetsetsa ntchito imayenera ndi khola dongosolo desulfurization ndi kukumana mochulukira okhwima zofunika zachilengedwe.
Rection sintered silicon carbide ceramics amatenga gawo losasinthika m'mafakitale azikhalidwe monga ng'anjo ndi makina ochotsa sulfure chifukwa cha mawonekedwe awo apadera komanso zabwino zomwe mungasinthe. Amapereka chitsimikiziro cholimba cha ntchito yabwino, yokhazikika, komanso yosamalira zachilengedwe popanga mafakitale ndikuyika chilimbikitso champhamvu pakukweza kwaukadaulo ndi chitukuko cha mafakitale azikhalidwe.
