Hauv cov tshuab ua kom cov pa roj flue desulfurization hauv kev lag luam, txawm hais tias lub nozzle me me, nws muaj lub luag haujlwm hnyav - nws ncaj qha txiav txim siab qhov ua tau zoo ntawm cov pa roj sulfurization thiab kev ruaj khov ntawm kev ua haujlwm ntawm cov khoom siv. Thaum muaj kev ua haujlwm hnyav xws li kub siab, xeb, thiab hnav, kev xaiv cov khoom siv tseem ceeb heev.Cov khoom siv silicon carbide ceramics, nrog lawv lub zog "nyuaj", tab tom dhau los ua qhov kev daws teeb meem nyiam hauv thaj chaw ntawm desulfurization nozzles.
1. Ntuj tiv taus xeb 'tiv thaiv khaub ncaws'
Cov kua qaub thiab alkaline hauv qhov chaw desulfurization zoo li "cov hniav tsis pom", thiab cov khoom siv hlau feem ntau tsis tuaj yeem dim ntawm kev poob corrosion. Lub zog tshuaj lom neeg ntawm silicon carbide ceramics muab nws nrog kev tiv thaiv corrosion muaj zog, thiab nws tuaj yeem nyob ruaj khov hauv cov chaw muaj kua qaub, ib yam li muab ib txheej ntawm cov cuab yeej tiv thaiv rau ntawm lub nozzle. Qhov no tsis yog tsuas yog ua kom lub nozzle ntev dua, tab sis kuj zam kev pheej hmoo ntawm desulfurization kua xau los ntawm corrosion.
2. Lub 'pawg neeg nyob twj ywm' thaum muaj kub siab
Thaum qhov kub hauv lub pej thuam desulfurization txuas ntxiv nce siab, ntau yam khoom siv yuav mos thiab deform. Txawm li cas los xij, silicon carbide ceramics tseem tuaj yeem khaws lawv daim ntawv qub ntawm qhov kub siab ntawm 1350 ℃, nrog rau qhov coefficient thermal expansion tsuas yog 1/4 ntawm cov hlau. Qhov kev ruaj khov kub siab tso cai rau lub nozzle los daws qhov kev poob siab thermal tau yooj yim. Tus cwj pwm no ntawm 'tsis ntshai thaum raug cua sov' ua kom ntseeg tau tias kev ua haujlwm tas mus li thiab ruaj khov ntawm lub kaw lus desulfurization.
3, Tus 'neeg khiav ntev' hauv ntiaj teb uas tsis yooj yim hnav
Cov dej ntws ceev ceev desulfurization slurry txuas ntxiv ntxuav phab ntsa sab hauv ntawm lub nozzle zoo li ntawv xuab zeb. Qhov nyuaj ntawm silicon carbide ceramics yog qhov thib ob tsuas yog pob zeb diamond, thiab nws qhov kev tiv thaiv kev hnav yog ntau zaus ntawm cov hlau cam khwb cia chromium siab. Lub zog 'hnyav ntaus' no ua rau lub nozzle tswj tau lub kaum sab xis thiab cov nyhuv atomization thaum lub sijhawm ntev flushing, zam kev txo qis hauv kev ua haujlwm desulfurization los ntawm kev hnav thiab tsim kua muag.
4, Tus 'invisible promoter' ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig
Ua tsaug rau qhov ceev ntawm cov khoom siv nws tus kheej, silicon carbide ceramic nozzles tuaj yeem ua tiav qhov sib npaug ntawm atomization effect, txhim kho qhov ua tau zoo ntawm cov tshuaj tiv thaiv ntawm limestone slurry thiab flue gas. Qhov "ob npaug ntawm qhov tshwm sim nrog ib nrab ntawm kev siv zog" no tsis yog tsuas yog txo qhov kev siv cov desulfurizers, tab sis kuj txo qhov kev siv zog ntawm lub cev, muab kev pab cuam tseem ceeb rau kev hloov pauv ntsuab ntawm cov lag luam.
Raws li kev txhawb nqa ntawm lub hom phiaj "ob chav carbon", qhov kev ntseeg tau thiab kev ua haujlwm ntev ntawm cov khoom siv tiv thaiv ib puag ncig tau nce ntxiv. Lub silicon carbide ceramic desulfurization nozzle muab "ib txoj haujlwm, kev khiav tawm ntev" kev daws teeb meem rau kev kho cov pa roj flue los ntawm kev tsim kho tshiab, nrog rau lub neej ua haujlwm ntev dua thiab kev ua haujlwm ruaj khov dua. Qhov kev tshawb pom tshiab ntawm "yeej nrog cov ntaub ntawv" no yog rov txhais dua tus qauv nqi ntawm cov txheej txheem desulfurization - kev xaiv cov ntaub ntawv tsim nyog yog nws tus kheej kev nqis peev zoo.
Ua ib lub tuam txhab uas mob siab rau kev tshawb fawb thiab kev tsim cov khoom siv silicon carbide ceramics, peb tau cog lus tias yuav muab cov khoom siv tiv thaiv ib puag ncig nrog "kev muaj zog" los ntawm cov khoom siv thev naus laus zis. Ua kom kev ua haujlwm ruaj khov ntawm txhua lub nozzle ua lub hauv paus txhim khu kev qha hauv kev sib ntaus sib tua los tiv thaiv lub ntuj xiav.
