Hauv kev tiv thaiv ib puag ncig ntawm kev tsim khoom lag luam, desulfurization yog ib kauj ruam tseem ceeb hauv kev tiv thaiv huab cua huv, thiab lub nozzle, raws li "core executor" ntawm desulfurization system, ncaj qha txiav txim siab qhov kev ua haujlwm ntawm desulfurization thiab khoom siv lub neej raws li nws qhov kev ua tau zoo. Ntawm ntau cov ntaub ntawv nozzle,silicon carbide (SiC)tau maj mam dhau los ua cov khoom nyiam hauv kev lag luam desulfurization vim nws qhov kev ua tau zoo tshwj xeeb, thiab tau dhau los ua tus pab cuam muaj zog rau cov lag luam kom ua tiav kev ua haujlwm siab thiab kev tiv thaiv ib puag ncig.
Tej zaum ntau tus neeg tsis paub txog silicon carbide. Yooj yim muab tso, nws yog ib qho khoom siv hluav taws xob uas tsis yog-hlau uas sib xyaw ua ke ntawm qhov kub thiab txias tsis kam ntawm ceramics nrog lub zog muaj zog ntawm cov hlau, zoo li "cov tub rog ruaj khov" uas tau tsim rau cov chaw ua haujlwm hnyav. Lub desulfurization nozzle ua los ntawm silicon carbide tag nrho siv qhov zoo ntawm cov khoom no.
Ua ntej, qhov muaj zog corrosion kuj yog qhov tseem ceeb ntawm silicon carbide desulfurization nozzles. Nyob rau hauv cov txheej txheem ntawm industrial desulfurization, desulfurizers feem ntau yog corrosive media nrog muaj zog acidity thiab alkalinity. Ordinary hlau nozzles tau yooj yim rau hauv lawv lub sijhawm ntev, uas tuaj yeem ua rau corrosion thiab to. Qhov no tsis tsuas yog cuam tshuam rau cov nyhuv desulfurization, tab sis kuj yuav tsum tau hloov ntau zaus, nce tus nqi ntawm lub lag luam. Silicon carbide cov ntaub ntawv nws tus kheej muaj cov tshuaj lom neeg ruaj khov thiab tuaj yeem tiv thaiv kev yaig ntawm cov kua qaub thiab alkalis. Txawm tias nyob rau hauv lub sij hawm ntev-kub kub corrosive ib puag ncig, nws muaj peev xwm tswj tau cov qauv kev ncaj ncees, zoo heev expanding lub neej kev pab cuam ntawm nozzles thiab txo cov khoom siv ntau zaus.
Secondly, nws zoo heev kub kuj ua rau nws haum rau ntau yam complex ua hauj lwm tej yam kev mob. Qhov kub ntawm cov pa roj tawm tawm los ntawm cov boilers, kilns thiab lwm yam khoom siv feem ntau yog siab, thiab cov nozzles ua los ntawm cov khoom siv feem ntau ua rau deformation thiab laus nyob rau hauv qhov kub thiab txias ib puag ncig, uas ua rau cov tshuaj tsuag tsis zoo thiab txo desulfurization efficiency. Silicon carbide muaj qhov kub thiab txias tsis kam. Nws tuaj yeem ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ntawm ntau pua degrees Celsius, thiab yuav tsis cuam tshuam rau cov qauv thiab kev ua haujlwm vim qhov kub hloov pauv, txhawm rau xyuas kom meej tias cov tshuaj tsuag tsis sib xws thiab muag heev, kom cov desulfurizer tuaj yeem tiv tauj nrog cov roj flue thiab txhim kho cov desulfurization efficiency.
Tsis tas li ntawd, qhov hnav tsis kam ntawm cov khoom siv silicon carbide yuav tsum tsis txhob qis dua. Thaum cov txheej txheem desulfurization khiav, ib qho me me ntawm cov khoom me me tuaj yeem muaj nyob rau hauv cov desulfurizer, uas yuav ua rau tsis tu ncua ntawm cov phab ntsa sab hauv ntawm lub nozzle. Tom qab lub nozzle zoo tib yam siv rau lub sijhawm ntev, lub aperture yuav loj dua thiab cov tshuaj tsuag yuav tsis zoo. Lub hardness ntawm silicon carbide yog siab heev, thiab nws cov hnav tsis kam yog siab dua li cov hlau thiab cov ceramics zoo tib yam. Nws tuaj yeem tiv taus qhov yaig thiab hnav ntawm cov khoom siv, tswj kev ruaj ntseg ntawm nozzle aperture, xyuas kom lub sij hawm ntev sib xws ntawm cov nyhuv tshuaj tsuag, thiab zam kev degradation ntawm desulfurization efficiency los ntawm nozzle hnav.
Nyob rau hauv qhov kev xav tau ntawm ib puag ncig nruj zuj zus, cov tuam txhab lag luam tsis yog tsuas yog xav tau kom ua tiav cov txheej txheem emissions, tab sis kuj nrhiav kev ua haujlwm zoo, ruaj khov, thiab tus nqi qis ntawm cov khoom tiv thaiv ib puag ncig. Lub silicon carbide desulfurization nozzle, nrog nws peb qhov zoo ntawm kev tiv thaiv corrosion, kub tsis kam, thiab hnav tsis kam, zoo haum rau cov kev xav tau ntawm kev lag luam desulfurization. Nws tuaj yeem txhim kho kev ua haujlwm ruaj khov ntawm desulfurization system thiab txo cov nqi kho khoom, ua qhov kev xaiv zoo rau kev lag luam ib puag ncig hloov khoom dua tshiab.
Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib txuas ntxiv ntawm silicon carbide cov khoom siv thev naus laus zis, nws daim ntawv thov hauv thaj chaw muaj kev tiv thaiv ib puag ncig yuav nthuav dav dua. Thiab cov silicon carbide desulfurization nozzle yuav txuas ntxiv pab cov lag luam ua tiav cov khoom lag luam ntsuab nrog nws cov kev ua tau zoo, pab txhawb ntxiv rau kev tiv thaiv lub ntuj xiav thiab huab cua dawb.
