Mu dziko lalikulu la mafakitale, maulalo ambiri ofunikira sangachite popanda thandizo la zipangizo zogwira ntchito bwino. Lero, tipereka zipangizo zomwe zimagwira ntchito yofunika kwambiri m'mafakitale achikhalidwe monga uvuni ndi makina ochotsera sulfurization -zoumbaumba za silicon carbide zozungulira zomwe zimapangidwa ndi reaction sintered.
Kodi silicon carbide ceramic ndi chiyani?
Silika ya silicon carbide ceramic ndi chinthu chapamwamba cha ceramic chopangidwa ndi silicon ndi kaboni. Si ceramic wamba, koma ndi "metamaterial" yokhala ndi makhalidwe abwino kwambiri. Ili ndi makhalidwe monga mphamvu yotentha kwambiri, kukana kuwonongeka bwino, kukhuthala kochepa kwa kutentha, kuuma kwambiri, komanso kukana dzimbiri kwa mankhwala, zomwe zimapangitsa kuti ikhale yosiyana ndi zipangizo zambiri.
Ma ceramic a silicon carbide opangidwa ndi Reaction sintered ndi mtundu wapadera wa ma ceramic a silicon carbide, ndipo njira yawo yokonzekera ndi yapadera kwambiri - choyamba, tinthu tating'onoting'ono ta alpha SiC ndi zowonjezera zimakanikizidwa mu thupi lobiriwira, kenako zimakhudzidwa ndi silicon yamadzimadzi kutentha kwambiri. Pakadali pano, kaboni yomwe ili m'malo opanda kanthu imakumana ndi zotsatira zabwino kwambiri za mankhwala ndi Si yolowetsedwa, ndikupanga β - SiC ndikulumikizana mwamphamvu ndi α - SiC. Nthawi yomweyo, silicon yaulere imadzaza ma pores, pamapeto pake imapanga zinthu zolemera kwambiri za ceramic.
Mwala wapangodya mu uvuni
Kuwotcha kwa zinthu za silicon carbide ndi gawo lofunika kwambiri m'mauvuni osiyanasiyana otentha kwambiri. Mwachitsanzo, m'mauvuni opanga zinthu za ceramic monga mauvuni ozungulira, mauvuni a tunnel, mauvuni oyenda pansi, ndi zina zotero, amapangidwa kukhala zinthu zofunika kwambiri monga manja a nozzle, ma crossbeam roller, ndi mapaipi a mpweya wozizira.
Chophimba cha moto chimatha kuwongolera bwino kutentha mkati mwa uvuni. Chili ndi mphamvu yotentha kwambiri, kukana okosijeni, kukana kuwonongeka, komanso kukana kuzizira ndi kutentha mwachangu. Sichidzasweka kapena kusokonekera mutagwiritsa ntchito kutentha kwa nthawi yayitali, zomwe zimapangitsa kuti kutentha kukhale kokhazikika mu uvuni. Ndikofunikira kwambiri poyatsira zinthu zadothi zapamwamba kwambiri.
Ma crossbeam rollers ndi ma ducts a mpweya wozizira motsatana amakhala ndi udindo wofunikira wothandizira ndi kupumira mpweya. Crossbeam rollers ali ndi makhalidwe a kukhazikika bwino kwa kutentha, kukana okosijeni, komanso kukana kutentha kwambiri. Sizosavuta kupotoza ndi kupindika mutagwiritsa ntchito nthawi yayitali kutentha kwambiri, kuonetsetsa kuti kapangidwe ka mkati mwa uvuni kakhazikika komanso kunyamula zinthu bwino. Crossbeam duct ndi yomwe imayang'anira kayendedwe ka mpweya ndi kutentha mkati mwa uvuni, kuonetsetsa kuti uvuni ukugwira ntchito bwino.
Kuchokera pakuwona magawo osinthidwa, reaction sintered silicon carbide ili ndi ubwino woonekeratu popanga zigawo za uvuni. Chifukwa cha kukula kwake kosasintha kwambiri isanayambe komanso itatha kusungunuka, imatha kusinthidwa kukhala mawonekedwe ndi kukula kulikonse ikapangidwa. Opanga uvuni amatha kusintha mawonekedwe ndi zofunikira zosiyanasiyana za zigawo malinga ndi mapangidwe osiyanasiyana a uvuni ndi zosowa zopangira, kukwaniritsa zofunikira pakupanga zinthu zazikulu komanso zovuta, zomwe zimakhala zovuta kuti zipangizo zina zikwaniritse.
Mzere wolimba woteteza dongosolo lochotsa sulfurization
Pankhani yoteteza chilengedwe monga kuyeretsa malo opangira magetsi, zida za silicon carbide zomwe zimapangidwa ndi reaction sintered nazonso zimagwira ntchito yofunika kwambiri, makamaka zomwe zimawonetsedwa mu gawo lofunika kwambiri la nozzles za desulfurization. Mpweya wotuluka kuchokera ku malo opangira magetsi uli ndi zinthu zambiri zoipitsa monga sulfur dioxide, ndipo nozzles za desulfurization ndi zida zofunika kwambiri pochotsa zinthu zoipitsa izi.
Mphuno ya desulfurization ya silicon carbide yopangidwa ndi reaction ili ndi makhalidwe abwino kwambiri monga mphamvu yayikulu, kuuma kwambiri, kukana dzimbiri mwamphamvu, kukana kuvala, komanso kukana kutentha kwambiri. Ili ndi moyo wodabwitsa pansi pa mikhalidwe yovuta, yomwe singafanane ndi zipangizo wamba. Mitundu ya mphuno ya desulfurization yomwe imagwiritsidwa ntchito kwambiri imaphatikizapo mphuno zozungulira ndi mphuno za vortex, zomwe zimakhala ndi mapangidwe osiyanasiyana ndi mfundo zogwirira ntchito, koma zimatha kupangitsa kuti desulfurizer ikhale ya atomiki bwino ndikuikhudza mokwanira ndi mpweya wa flue, motero zimapangitsa kuti desulfurization ikhale yabwino.
Kudzera mu kapangidwe kake kapadera, mphuno yozungulira imapangitsa madzi omwe ali mu gawo lakunja kugunda pamwamba pa mphuno pa ngodya inayake, kusintha njira yopopera ndikutuluka mu mphuno, ndikupanga malo olimba okhala ndi chifunga, omwe angapereke ma angles osiyanasiyana opopera, ndipo amakhalabe ndi mphamvu yoyamwa bwino pansi pa kupsinjika kochepa. mphuno yozungulira imalola matope kulowa mu chipinda chozungulira cha mphuno kuchokera mbali ya tangent, kenako nkutulutsa kuchokera ku mphuno pa ngodya zolondola kupita ku mbali yolowera. mphuno ndi yaying'ono komanso yofanana, ndipo njira yozungulira ndi yayikulu, yomwe si yosavuta kuitseka.
Pazigawo zomwe zasinthidwa mwamakonda za machitidwe ochotsa sulfurization, silicon carbide yopangidwa ndi reaction sintered imatha kusintha mawonekedwe a nozzle, kukula, ndi mawonekedwe opopera oyenera kwambiri malinga ndi njira zosiyanasiyana zochotsera sulfurization, kuchuluka kwa mpweya wotuluka m'madzi, kuchuluka kwake, ndi magawo ena, kuonetsetsa kuti makina ochotsera sulfurization akugwira ntchito bwino komanso mokhazikika komanso kukwaniritsa zofunikira zachilengedwe zomwe zikuchulukirachulukira.
Zida za silicon carbide zozungulira zomwe zimapangidwa ndi Reaction sintered zimagwira ntchito yofunika kwambiri m'mafakitale achikhalidwe monga ma uvuni ndi makina oyeretsera sulfur chifukwa cha makhalidwe awo apadera komanso zabwino zomwe zingasinthidwe. Zimapereka chitsimikizo cholimba cha magwiridwe antchito abwino, okhazikika, komanso oteteza chilengedwe popanga mafakitale ndipo zimathandizira kwambiri pakukweza ukadaulo ndi chitukuko cha mafakitale achikhalidwe.
