Silicon carbide desulfurization nozzle: me me, zoo heev

Hauv kev kho cov pa roj flue hauv kev lag luam, lub kaw lus desulfurization ua lub luag haujlwm tseem ceeb, thiab ib qho khoom tsis tseem ceeb - lub nozzle, cuam tshuam ncaj qha rau kev ua haujlwm zoo thiab kev ruaj khov ntawm tag nrho lub kaw lus. Nyob rau hauv xyoo tas los no,Cov nozzles desulfurization ua los ntawm silicon carbide khoomtau maj mam dhau los ua qhov nyiam tshiab ntawm kev lag luam. Niaj hnub no, cia peb tham txog lawv cov yam ntxwv tshwj xeeb.
Silicon carbide yog dab tsi?
Silicon carbide (SiC) yog ib qho sib xyaw ua los ntawm silicon thiab carbon, uas muaj qhov nyuaj heev thiab zoo heev rau qhov kub thiab txias thiab corrosion. Nws qhov Mohs hardness yog siab txog li 9.5, thib ob tsuas yog pob zeb diamond, uas txhais tau tias nws tsis yooj yim hnav. Tib lub sijhawm, silicon carbide tuaj yeem tswj tau qhov ruaj khov hauv qhov kub siab tshaj 1350 ℃, uas ua rau nws muaj txiaj ntsig zoo hauv kev ua haujlwm hnyav.
Vim li cas ho xaiv silicon carbide ua lub nozzle desulfurization?
Qhov chaw ua haujlwm ntawm desulfurization nozzles tuaj yeem piav qhia tias "hnyav":
- Kev raug tshuaj lom neeg ntev ntev rau cov kua qaub thiab alkaline corrosive slurries
- Kev ntxuav kua dej sai sai
- Kev hloov pauv kub loj heev
-Tej zaum yuav muaj cov khoom khov kho

Cov taub hau hlau ib txwm muaj feem yuav xeb thiab hnav, thaum cov taub hau yas tsis tiv taus cua sov. Lub taub hau silicon carbide nozzle them rau cov qhov tsis zoo no, thiab nws cov txiaj ntsig tseem ceeb suav nrog:
1. Super muaj zog corrosion tsis kam
Silicon carbide muaj kev tiv thaiv zoo heev rau cov xov xwm corrosive xws li acid, alkali, thiab ntsev, thiab nws lub neej ua haujlwm ntev dua li cov hlau thiab yas nozzles.
2. Kev hnav tsis kam zoo heev
Txawm hais tias cov slurry muaj cov khoom khov kho, lub silicon carbide nozzle tuaj yeem tswj tau qhov kev ua haujlwm txau ruaj khov rau lub sijhawm ntev thiab tsis yooj yim hloov pauv lub kaum sab xis vim hnav.
3. Kev ua haujlwm kub siab
Hauv cov chaw muaj pa roj kub heev, cov silicon carbide nozzles yuav tsis deform lossis mos, ua kom muaj kev txau tshuaj ruaj khov.
4. Kev ua tau zoo ntawm cov cua sov
Pab lub nozzle kom dissipate cua sov sai sai thiab txo qhov kev puas tsuaj ntawm thermal stress.
Txoj cai ua haujlwm ntawm silicon carbide nozzle
Lub silicon carbide desulfurization nozzle atomizes cov desulfurization slurry (feem ntau yog limestone slurry) rau hauv cov tee dej me me, uas tuaj rau hauv kev sib cuag tag nrho nrog cov roj flue, ua rau cov alkaline tshuaj hauv cov slurry kom tshuaj lom neeg nrog cov sulfur dioxide hauv cov roj flue, yog li ua tiav lub hom phiaj ntawm desulfurization.
Tus qauv tsim thiab cov khoom siv ntawm lub nozzle ncaj qha cuam tshuam rau qhov cuam tshuam atomization:
-Cov khoom me me uas muaj cov atomized me me, qhov loj dua ntawm thaj chaw sib cuag, thiab qhov siab dua ntawm kev ua haujlwm desulfurization
-Cov khoom siv silicon carbide ua kom lub qhov nozzle aperture ruaj khov mus sij hawm ntev, zam kev txo qis ntawm cov nyhuv atomization vim hnav thiab tsim kua muag
Cov xwm txheej ntawm daim ntawv thov
Silicon carbide desulfurization nozzles yog dav siv rau hauv:
-Lub zog fais fab thermal
-Hlau cog
-Cov chaw hlawv khib nyiab
-Lwm cov lag luam kev lag luam uas xav tau cov roj flue desulfurization
Cov lus qhia txog kev saib xyuas txhua hnub
Txawm hais tias cov nozzles silicon carbide muaj zog ruaj khov, kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua tseem ceeb heev:
- Tshawb xyuas seb lub nozzle puas raug thaiv lossis hnav tas li
-Txhawb kom ua haujlwm zoo ntawm lub kaw lus lim dej slurry
- Hloov lub nozzle sai li sai tau thaum pom tias kev ua haujlwm tsis zoo
kev xaus lus
Txawm hais tias lub silicon carbide desulfurization nozzle tsuas yog ib qho me me hauv lub desulfurization system, nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho desulfurization efficiency thiab txo cov nqi khiav lag luam. Nws tau dhau los ua qhov kev xaiv nyiam rau ntau thiab ntau lub tuam txhab vim nws qhov kev tiv thaiv corrosion zoo heev, hnav tsis kam, thiab kub tsis kam.
Kev xaiv cov khoom siv thiab tsim qauv nozzle tsim nyog tsis yog tsuas yog txhim kho cov cim qhia ib puag ncig xwb, tab sis kuj coj cov txiaj ntsig kev lag luam mus sij hawm ntev rau lub tuam txhab. Hauv cov kev cai ib puag ncig niaj hnub no, silicon carbide desulfurization nozzles ntsiag to tiv thaiv peb lub ntuj xiav.
