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 kev huv ntawm huab cua, thiab lub nozzle, ua "tus thawj coj tseem ceeb" ntawm lub kaw lus desulfurization, txiav txim siab ncaj qha rau kev ua haujlwm desulfurization thiab lub neej khoom siv raws li nws cov kev ua tau zoo. Ntawm ntau cov ntaub ntawv nozzle,silicon carbide (SiC)tau maj mam dhau los ua cov khoom siv nyiam hauv kev lag luam desulfurization vim nws qhov kev ua tau zoo tshwj xeeb, thiab tau dhau los ua tus pabcuam muaj zog rau cov tuam txhab kom ua tiav kev ua haujlwm siab thiab kev tiv thaiv ib puag ncig.
Tej zaum ntau tus neeg tsis paub txog silicon carbide. Hais yooj yim xwb, nws yog ib yam khoom siv inorganic uas tsis yog hlau uas ua los ntawm cov khoom siv inorganic uas ua ke nrog cov khoom siv ceramics uas muaj zog heev, zoo li "tus tub rog ruaj khov" uas tsim los rau cov chaw ua haujlwm hnyav. Lub nozzle desulfurization ua los ntawm silicon carbide siv tag nrho cov txiaj ntsig ntawm cov khoom siv no.
Ua ntej, qhov muaj zog tiv taus corrosion yog qhov tseem ceeb ntawm silicon carbide desulfurization nozzles. Hauv cov txheej txheem ntawm kev lag luam desulfurization, desulfurizers feem ntau yog cov xov xwm corrosive heev nrog acidity thiab alkalinity muaj zog. Cov hlau nozzles ib txwm yooj yim raus rau hauv lawv ntev, uas tuaj yeem ua rau corrosion thiab to. Qhov no 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. Cov khoom siv silicon carbide nws tus kheej muaj kev ruaj khov tshuaj zoo heev thiab tuaj yeem tiv taus kev puas tsuaj ntawm cov kua qaub thiab alkalis muaj zog. Txawm tias nyob rau hauv lub sijhawm ntev kub-corrosive ib puag ncig, nws tuaj yeem tswj tau qhov kev ua haujlwm ntawm cov nozzles, ua rau lub neej kev pabcuam ntev dua thiab txo cov khoom siv kho zaus.
Qhov thib ob, nws qhov kev tiv taus kub zoo heev ua rau nws haum rau ntau yam kev ua haujlwm nyuaj. Qhov kub ntawm cov pa roj flue uas tso tawm los ntawm cov boilers, kilns thiab lwm yam khoom siv feem ntau siab, thiab cov nozzles ua los ntawm cov khoom siv feem ntau yuav deformation thiab laus hauv qhov chaw kub siab, ua rau cov tshuaj tsuag tsis zoo thiab txo qis desulfurization efficiency. Silicon carbide muaj kev tiv taus kub zoo heev. Nws tuaj yeem ua haujlwm ruaj khov hauv cov pa roj flue kub siab ntawm ntau pua degrees Celsius, thiab yuav tsis cuam tshuam rau cov qauv thiab kev ua tau zoo vim qhov kub hloov pauv, yog li kom ntseeg tau tias cov tshuaj tsuag yog sib xws thiab mos, yog li ntawd lub desulfurizer tuaj yeem sib cuag tag nrho nrog cov pa roj flue thiab txhim kho cov desulfurization efficiency.
Tsis tas li ntawd xwb, qhov kev tiv thaiv kev hnav ntawm cov khoom siv silicon carbide yuav tsum tsis txhob raug kwv yees qis. Thaum lub kaw lus desulfurization khiav, yuav muaj me me ntawm cov khoom khov hauv lub desulfurizer, uas yuav ua rau muaj kev hnav tas mus li ntawm phab ntsa sab hauv ntawm lub nozzle. Tom qab siv lub nozzle ib txwm ntev, qhov aperture yuav loj dua thiab cov tshuaj tsuag yuav tsis sib haum. Qhov nyuaj ntawm silicon carbide siab heev, thiab nws qhov kev tiv thaiv kev hnav siab dua li cov hlau thiab cov khoom siv ceramic ib txwm. Nws tuaj yeem tiv taus kev yaig thiab kev hnav ntawm cov khoom khov, tswj qhov ruaj khov ntawm qhov aperture nozzle, xyuas kom meej tias cov tshuaj tsuag muaj zog ntev, thiab zam kev puas tsuaj ntawm kev ua haujlwm desulfurization los ntawm kev hnav nozzle.
Nyob rau hauv qhov kev cai ib puag ncig uas nruj zuj zus, cov lag luam tsis yog tsuas yog xav tau cov pa phem xwb, tab sis kuj tseem yuav tsum ua kom muaj kev ua haujlwm zoo, ruaj khov, thiab pheej yig ntawm cov khoom siv tiv thaiv ib puag ncig. Lub silicon carbide desulfurization nozzle, nrog nws peb qhov zoo tseem ceeb ntawm kev tiv thaiv corrosion, kub siab, thiab hnav tsis kam, zoo meej rau cov kev xav tau ntawm kev lag luam desulfurization. Nws tuaj yeem txhim kho kev ua haujlwm ruaj khov ntawm lub kaw lus desulfurization thiab txo cov nqi kho khoom siv, ua qhov kev xaiv zoo rau kev txhim kho ib puag ncig ntawm cov tuam txhab.
Yav tom ntej, nrog rau kev nce qib tas mus li ntawm cov thev naus laus zis npaj cov khoom siv silicon carbide, nws daim ntawv thov hauv kev tiv thaiv ib puag ncig kev lag luam yuav dav dua. Thiab lub silicon carbide desulfurization nozzle yuav txuas ntxiv pab cov tuam txhab ua tiav cov khoom ntsuab nrog nws cov kev ua tau zoo hardcore, pab txhawb ntau dua rau kev tiv thaiv lub ntuj xiav thiab huab dawb.
