Hauv cov txheej txheem tiv thaiv ib puag ncig ntawm kev tsim khoom lag luam, desulfurization yog ib kauj ruam tseem ceeb hauv kev tiv thaiv lub ntuj xiav, thiab lub nozzle, ua "lub hauv paus tseem ceeb" ntawm lub kaw lus desulfurization, txiav txim siab ncaj qha rau kev ua haujlwm desulfurization thiab lub neej khoom siv. Nyob rau hauv xyoo tas los no,Cov nozzles desulfurization ua los ntawm silicon carbideCov ntaub ntawv tau maj mam dhau los ua qhov kev xaiv tseem ceeb hauv kev lag luam. Dab tsi ua rau cov ntaub ntawv zoo li "kev tshaj lij" no sawv tawm?
Qhov tseeb, silicon carbide tsis yog "khoom siv tshiab". Nws yog cov khoom siv tsis yog hlau uas tsim los ntawm cov khoom siv inorganic, thiab nws qhov tshwj xeeb tshaj plaws yog nws "lub zog nyuaj" - kev tiv taus kub siab, kev tiv taus corrosion, thiab kev hnav tsis kam ntau dua li cov hlau lossis yas ib txwm muaj. Thaum lub sijhawm desulfurization, cov tshuaj tsuag slurry feem ntau muaj zog corrosiveness thiab qhov kub tsis qis. Cov nozzles ib txwm yuav sai sai no ntsib teeb meem xws li hnav, corrosion, thiab blockage, uas tsis tsuas yog cuam tshuam rau qhov desulfurization nyhuv tab sis kuj xav tau hloov pauv ntau zaus, ua rau tus nqi ntawm lub tuam txhab nce ntxiv. Silicon carbide nozzles tuaj yeem yooj yim daws cov chaw ib puag ncig hnyav no, txawm tias lawv raug rau corrosive slurries ntev, lawv tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv, tsis yooj yim deformed lossis thaiv, thiab txo qhov zaus txij nkawm.
Ntxiv rau qhov ruaj khov, lub nozzle silicon carbide kuj muaj peev xwm ua haujlwm zoo heev. Nws cov qauv tsim yog ua raws li qhov yuav tsum tau ua ntawm kev txau desulfurization, tso cai rau cov slurry los ua cov dej me me thiab sib npaug uas kov tag nrho cov pa flue, ua rau cov tshuaj desulfurization ua haujlwm ntau dua. Ntxiv mus, silicon carbide nws tus kheej yog lub teeb yuag, muaj zog heev, thiab yooj yim rau kev teeb tsa, tsis muaj kev cuam tshuam ntxiv rau lub kaw lus desulfurization.
Tej zaum ib txhia neeg yuav xav tias "cov ntaub ntawv tshwj xeeb yeej kim heev", tab sis thaum kawg, qhov kev siv nyiaj ntawm silicon carbide nozzles yeej siab dua. Nws lub neej ua haujlwm yog ntau zaus dua li cov nozzles ib txwm muaj, txo cov nqi hloov pauv thiab lub sijhawm txij nkawm tsis ua haujlwm, txuag cov nuj nqis rau cov lag luam, thaum tseem ua kom muaj kev ua haujlwm desulfurization ruaj khov thiab pab cov lag luam daws teeb meem kev ntsuam xyuas ib puag ncig.
Niaj hnub nim no, cov kev cai tiv thaiv ib puag ncig tau dhau los ua nruj dua, thiab cov tuam txhab muab qhov tseem ceeb ntxiv rau "kev ua haujlwm zoo, kev ruaj khov, thiab kev thaj yeeb nyab xeeb" thaum xaiv cov khoom siv tiv thaiv ib puag ncig. Silicon carbide desulfurization nozzles tau dhau los ua qhov kev xaiv zoo tshaj plaws rau ib puag ncig rau ntau lub tuam txhab kev lag luam vim lawv cov khoom siv zoo. Qhov 'khoom siv thev naus laus zis nyuaj' zais rau hauv lub kaw lus desulfurization tiv thaiv qhov sib npaug ntawm kev tsim khoom lag luam thiab lub ntuj xiav thiab huab dawb nrog nws lub zog, thiab muab kev txhawb nqa txhim khu kev qha rau kev txhim kho ntsuab ntawm cov tuam txhab.
