Hauv kev lag luam flue roj desulfurization tshuab, txawm hais tias lub nozzle me me, nws muaj lub luag haujlwm hnyav - nws ncaj qha txiav txim siab qhov kev ua haujlwm ntawm desulfurization thiab cov cuab yeej ua haujlwm ruaj khov. Nyob rau hauv lub ntsej muag ntawm hnyav ua hauj lwm tej yam kev mob xws li kub, corrosion, thiab hnav, kev xaiv cov khoom yuav tsum yog ib qho tseem ceeb.Silicon carbide ceramics, nrog rau lawv lub hauv paus "lub zog nyuaj", tab tom dhau los ua kev daws teeb meem hauv thaj chaw ntawm desulfurization nozzles.
1, Ib txwm corrosion-resistant 'tiv thaiv armor'
Cov kua qaub thiab alkaline xov xwm nyob rau hauv ib puag ncig desulfurization zoo li "tsis pom cov hniav", thiab cov ntaub ntawv hlau zoo tib yam feem ntau tsis tuaj yeem dim kev puas tsuaj. Cov tshuaj inertness ntawm silicon carbide ceramics endows nws muaj zog corrosion kuj, thiab nws muaj peev xwm nyob ruaj khov nyob rau hauv muaj zog acid ib puag ncig, ib yam li muab ib tug txheej ntawm tiv thaiv armor ntawm lub nozzle. Qhov no feature tsis tsuas yog ncua lub neej ntawm lub nozzle, tab sis kuj zam qhov kev pheej hmoo ntawm desulfurization kua to los ntawm corrosion.
2 、 Lub 'cev pawg' nyob rau hauv qhov kub thiab txias
Thaum qhov kub hauv lub desulfurization ntauwd tseem nce ntxiv, ntau cov ntaub ntawv yuav soften thiab deform. Txawm li cas los xij, silicon carbide ceramics tseem tuaj yeem tuav lawv daim ntawv qub ntawm qhov kub ntawm 1350 ℃, nrog rau thermal expansion coefficient tsuas yog 1/4 ntawm cov hlau. Lub siab kub stability tso cai rau lub nozzle tiv thaiv thermal shock nrog yooj yim. Cov yam ntxwv ntawm 'tsis ntshai thaum raug tshav kub' ua kom muaj kev ua haujlwm tsis tu ncua thiab ruaj khov ntawm desulfurization system.
3 、 Tus 'ntiaj teb khiav deb' hauv lub ntiaj teb hnav-tiv taus
Lub high-ceev ntws desulfurization slurry tsis tu ncua ntxuav lub puab phab ntsa ntawm lub nozzle zoo li cov ntawv xuab zeb. Lub hardness ntawm silicon carbide ceramics yog thib ob tsuas yog pob zeb diamond, thiab nws cov hnav tsis kam yog ob peb zaug ntawm siab chromium cam khwb cia hlau. Qhov no 'nyuaj tsoo' lub zog ua rau lub nozzle kom muaj lub kaum ntse ntse txau thiab cov nyhuv atomization thaum lub sij hawm ntev dej yaug, zam qhov txo qis hauv desulfurization efficiency tshwm sim los ntawm kev hnav thiab tsim kua muag.
4, Tus 'tsis pom kev txhawb nqa' ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig
Ua tsaug rau qhov siab ceev ntawm cov khoom nws tus kheej, silicon carbide ceramic nozzles tuaj yeem ua tiav cov nyhuv atomization ntau dua, txhim kho cov tshuaj tiv thaiv ntawm limestone slurry thiab flue gas. Qhov no "ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog" feature tsis tsuas yog txo qhov kev siv ntawm desulfurizers, tab sis kuj txo cov kev siv zog ntawm lub cev, muab kev pab cuam rau kev hloov pauv ntsuab ntawm kev lag luam.
Raws li kev txhawb nqa ntawm "dual carbon" lub hom phiaj, kev ntseeg siab thiab kev ua haujlwm ntev ntawm cov cuab yeej tiv thaiv ib puag ncig tau nce ntxiv. Lub silicon carbide ceramic desulfurization nozzle muab "ib qho kev ua haujlwm, kev khiav tawm ntev" kev daws teeb meem rau kev lag luam flue gas kev kho mob los ntawm cov khoom siv tshiab, nrog lub neej ua haujlwm ntev thiab kev ua haujlwm ruaj khov. Qhov kev sib tw thev naus laus zis ntawm "kev yeej nrog cov ntaub ntawv" yog rov hais dua tus qauv tus nqi ntawm cov tshuab desulfurization - xaiv cov ntaub ntawv tsim nyog yog nws tus kheej qhov kev nqis peev zoo.
Raws li lub tuam txhab mob siab rau kev tshawb fawb thiab kev txhim kho ntawm silicon carbide ceramics, peb tau cog lus tias yuav muab cov cuab yeej tiv thaiv ib puag ncig uas muaj zog "qhov tseem ceeb" los ntawm cov khoom siv thev naus laus zis. Ua kom ruaj khov ua haujlwm ntawm txhua lub nozzle lub hauv paus txhim khu kev qha hauv kev sib ntaus sib tua los tiv thaiv lub ntuj xiav.
