Kukana dzimbiri kwa zipangizo n'kofunika kwambiri pakupanga mafakitale. Lero, tifufuza momwe zinthuzi zimagwirira ntchito bwino.zinthu za silicon carbidepankhani yolimbana ndi dzimbiri.
Silicon carbide ndi chinthu chopangidwa ndi silicon ndi carbon, chomwe chili ndi kapangidwe kake ka kristalo komanso zinthu zina zapadera. Kuchokera pakuwona kwa microscopic, maatomu a silicon ndi maatomu a carbon mu silicon carbide amalumikizidwa mwamphamvu kudzera mu ma covalent bonds, ndikupanga kapangidwe kokhazikika ka lattice. Izi zimapatsa silicon carbide kukhazikika kwa mankhwala komanso kuthekera kokana dzimbiri kuchokera ku zinthu zosiyanasiyana zamakemikolo, zomwe ndi chifukwa chachikulu chokana dzimbiri.
Mu mafakitale ambiri, zida zimakumana ndi vuto la dzimbiri. Mwachitsanzo, m'mafakitale opangira magetsi otentha, kuyaka kwa malasha kumapanga mpweya wambiri wa flue wokhala ndi sulfure. Mpweya wa acidic monga sulfure dioxide mu mpweya wa flue uwu umapanga zinthu zowononga monga sulfurous acid ndi sulfuric acid zikakumana ndi madzi. Ngati zipangizo za desulfurization zili ndi kukana kwa dzimbiri, zidzayamba kuzizira mofulumira, zomwe zimakhudza ntchito yanthawi zonse komanso moyo wautumiki wa zidazo.
Monga gawo lofunika kwambiri mu dongosolo lochotsa sulfurization, malo ogwirira ntchito a nozzle yochotsa sulfurization ndi ovuta kwambiri. Sikuti amangofunika kupirira kuwonongeka kwa mpweya wotentha kwambiri, komanso amakumana ndi zotsukira sulfurizers monga miyala yamtengo wapatali kwa nthawi yayitali. Mu malo awa, nozzle zopangidwa ndi zipangizo wamba zimakhala ndi dzimbiri, kuwonongeka, kutsekeka, ndi mavuto ena, zomwe zimapangitsa kuti ntchito yochotsa sulfurization ichepe komanso imafunika kusintha nozzle pafupipafupi, zomwe zimapangitsa kuti ndalama zokonzera ziwonjezeke komanso nthawi yopuma ichepe.
Zinthu zopangidwa ndi silicon carbide zimakhala ndi ubwino waukulu m'malo otere. Kukana kwake dzimbiri kumathandizira kuti igwire ntchito bwino kwa nthawi yayitali, kuchepetsa bwino kulephera komwe kumachitika chifukwa cha dzimbiri. Ngakhale ikakumana ndi zotsukira zamphamvu za acidic kapena alkaline kwa nthawi yayitali, nozzle ya silicon carbide desulfurization siiwonongeka mosavuta, zomwe zimapangitsa kuti dongosolo la desulfurization ligwire ntchito bwino. Kuphatikiza pa kukana dzimbiri, silicon carbide ilinso ndi kuuma kwakukulu, mphamvu yayikulu, komanso kukana kuvala bwino. Makhalidwe amenewa amathandiza nozzle ya silicon carbide desulfurization kuti ipitirize kugwira ntchito bwino ngakhale ikukumana ndi mpweya wothamanga kwambiri komanso kuwonongeka kwa tinthu tating'onoting'ono tolimba, zomwe zimakulitsa kwambiri moyo wa nozzle.
Zopangidwa ndi silicon carbide zimagwira ntchito yofunika kwambiri pakupanga ma nozzles ochotsa sulfur chifukwa cha kukana kwawo dzimbiri, zomwe zimapereka chitsimikizo champhamvu cha magwiridwe antchito abwino komanso okhazikika a mafakitale. Ndi kupita patsogolo kosalekeza kwa ukadaulo, zida za silicon carbide zipitiliza kuwonetsa phindu lawo lapadera m'magawo ambiri mtsogolo, ndikuyika mphamvu zatsopano mu chitukuko cha mafakitale.
