Hauv daim duab loj ntawm kev tsim khoom lag luam, yeej ib txwm muaj qee yam khoom me me uas ntsiag to ua cov haujlwm tseem ceeb. Lub silicon carbide desulfurization nozzle yog ib tug "hero tom qab scenes" - nws nkaum hauv lub pej thuam desulfurization ntawm cov chaw tsim hluav taws xob thiab cov chaw tsim hlau, txhua hnub "ntxuav" cov pa roj flue kev lag luam, cuam tshuam cov sulfur dioxide ua ntej tso tawm. Dab tsi yog qhov tshwj xeeb ntawm lub cuab yeej precision no ua los ntawm cov khoom siv silicon carbide?
1. Vim li cas thiaj siv silicon carbide? Cov pob txha tawv hauv cov khoom siv
Yuav kom nkag siab txog qhov zoo ntawmsilicon carbide desulfurization nozzles, peb yuav tsum pib nrog lawv "kev cai lij choj". Silicon carbide yog cov khoom siv inorganic uas tau tsim los ntawm kev dag, nrog cov atoms sib txuas los ntawm cov kev sib txuas covalent muaj zog heev los tsim cov qauv ruaj khov zoo li pob zeb diamond. Cov qauv no muab nws nrog peb "lub zog loj":
Tiv taus xeb: Cov pa roj flue kev lag luam yog sib xyaw nrog cov tshuaj corrosive xws li acid pos huab thiab limestone slurry, thiab cov hlau nozzles ib txwm yuav sai sai no corroded thiab riddled nrog qhov. Silicon carbide muaj kev tiv thaiv ntau dua rau acid thiab alkali dua li cov hlau, thiab tuaj yeem tswj tau qhov kev ua kom zoo txawm tias tom qab lub sijhawm ntev immersion hauv qhov chaw corrosive heev.
Muaj peev xwm tiv taus qhov kub siab: Qhov kub ntawm cov pa roj flue hauv lub pej thuam desulfurization feem ntau ncav cuag ntau pua degrees Celsius, thiab qee zaum yuav muaj qhov sib txawv ntawm qhov kub thiab txias vim yog cov khoom siv pib thiab kaw. Lub zog thermal ntawm silicon carbide muaj zog heev, thiab nws tsis yooj yim tawg txawm tias muaj kev cuam tshuam kub tam sim ntawd. Nws tseem txhim khu kev qha nyob rau hauv qhov kub thiab txias heev.
Yuav tiv taus kev hnav thiab tsim kua muag: Thaum cov dej ntws ceev ceev desulfurization slurry hla dhau lub nozzle, nws yuav txuas ntxiv mus rau sab hauv phab ntsa. Qhov nyuaj ntawm silicon carbide yog qhov thib ob tsuas yog pob zeb diamond, thiab nws tuaj yeem yooj yim tiv taus hom kev hnav no. Nws lub neej kev pabcuam yog ntau zaus ntawm cov yas lossis hlau nozzles.
2, Tsis yog tsuas yog 'ruaj khov' xwb, tab sis kuj yog 'booster' rau kev ua haujlwm desulfurization
Tus nqi ntawm silicon carbide desulfurization nozzles mus deb tshaj qhov "ntev ntev". Nws tus qauv tsim zais ib qho tsis paub meej: cov kav dej sab hauv tso cai rau cov desulfurization slurry kom sib xyaw thiab sib tsoo hauv cov dej ntws, thaum kawg atomizing rau hauv cov dej me me thiab sib xws - qhov loj dua qhov sib cuag ntawm cov dej no thiab cov pa roj flue, qhov siab dua ntawm kev nqus sulfur dioxide.
Qhov tseem ceeb tshaj, nws tsis yooj yim txhaws. Cov khoom me me yuav tsum tau sib xyaw rau hauv cov slurries kev lag luam, thiab cov channel nqaim ntawm cov nozzles ib txwm yooj yim thaiv, ua rau kev txau tsis sib npaug thiab txo qis desulfurization efficiency. Tus qauv tsim ntawm cov channel ntws ntawm silicon carbide nozzle yog qhov dav, tso cai rau cov khoom me me kom dhau mus zoo, txo qis lub sijhawm tsis ua haujlwm thiab kev txij nkawm los ntawm kev thaiv.
3. Qhov 'kev xaiv tseem ceeb' raws li cov cai tiv thaiv ib puag ncig
Nrog rau cov qauv ib puag ncig uas nruj zuj zus, cov lag luam muaj cov kev xav tau ntau dua rau cov khoom siv desulfurization. Piv txwv li, qhov kev txwv ntawm cov sulfur dioxide hauv cov pa roj flue uas cov chaw tsim hluav taws xob tso tawm tau nruj dua. Qhov no txhais tau tias lub kaw lus desulfurization yuav tsum ua haujlwm tau zoo dua thiab ruaj khov - thiab kev ua haujlwm ntawm lub nozzle cuam tshuam ncaj qha rau qhov txiaj ntsig kawg ntawm kev ntxuav.
Txawm hais tias tus nqi pib ntawm cov silicon carbide desulfurization nozzles siab dua li cov nozzles ib txwm muaj, lawv yeej pheej yig dua yav tom ntej. Nws lub neej ua haujlwm ntev dua li cov yas nozzles ntau zaus, uas tuaj yeem txo qhov zaus hloov pauv thiab kev poob sijhawm tsis ua haujlwm. Rau cov lag luam uas nrhiav kev tsim khoom ruaj khov, tus yam ntxwv ntawm "kev nqis peev ib zaug, tsis muaj kev txhawj xeeb mus sij hawm ntev" yog qhov tseem ceeb heev.
4, Tsis yog tsuas yog desulfurization, yav tom ntej daim ntawv thov yog pom
Ntxiv rau kev kho cov pa roj flue hauv kev lag luam, lub peev xwm ntawm cov ntaub ntawv silicon carbide tau tshwm sim hauv ntau qhov chaw. Nws qhov kev tiv taus kub siab thiab kev tiv taus hluav taws xob ua rau nws sawv tawm hauv cov chaw siab xws li lub zog nuclear thiab aerospace; Hauv kev lag luam zog tshiab, nws kuj siv rau hauv cov khoom siv sintering kub siab rau cov ntaub ntawv roj teeb lithium. Ua lub nozzle desulfurization, nws tseem yog ib feem tseem ceeb ntawm kev tswj hwm ib puag ncig tam sim no.
Qhov 'me me' no uas zais rau hauv lub pej thuam desulfurization yog qhov tseeb yog tus choj ntawm kev vam meej hauv kev lag luam thiab kev tiv thaiv ecological. Nws siv kev txawj ntse ntawm kev tshawb fawb txog cov ntaub ntawv los ua kom muaj peev xwm tsim khoom lag luam nrog lub ntuj xiav thiab huab dawb - tej zaum qhov kev txhais lus zoo tshaj plaws ntawm thev naus laus zis tiv thaiv ib puag ncig.
