Hauv kev lag luam flue roj kev kho mob, lub desulfurization system plays lub luag haujlwm tseem ceeb, thiab ib qho zoo li qhov tsis tseem ceeb - lub nozzle, cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ruaj ntseg ntawm tag nrho cov kab ke. Nyob rau xyoo tas los no,desulfurization nozzles ua los ntawm cov khoom siv silicon carbidetau maj mam dhau los ua tus nyiam tshiab ntawm kev lag luam. Niaj hnub no, cia peb tham txog lawv cov yam ntxwv tshwj xeeb.
Dab tsi yog silicon carbide?
Silicon carbide (SiC) yog ib qho kev sib xyaw ua ke ntawm silicon thiab carbon, uas muaj qhov nyuaj siab heev thiab zoo heev kub thiab corrosion kuj. Nws Mohs hardness yog siab li 9.5, thib ob tsuas yog pob zeb diamond, uas txhais tau hais tias nws hnav-resistant heev. Nyob rau tib lub sijhawm, silicon carbide tuaj yeem tswj hwm kev ruaj ntseg hauv qhov chaw kub siab tshaj 1350 ℃, uas ua rau nws muaj txiaj ntsig zoo hauv kev ua haujlwm hnyav.
Vim li cas thiaj xaiv silicon carbide ua lub desulfurization nozzle?
Qhov chaw ua haujlwm ntawm desulfurization nozzles tuaj yeem piav qhia tias "hnyav":
-Long lub sij hawm raug rau acidic thiab alkaline corrosive slurries
- Kev kub ceev ua kua dej ntws tawm
-Qhov kub hloov pauv loj
-Tej zaum yuav muaj cov khoom siv
Ib txwm hlau nozzles muaj kev tiv thaiv corrosion thiab hnav, thaum cov yas nozzles tsis muaj cua sov. Lub silicon carbide nozzle precisely compensates rau cov shortcomings, thiab nws lub ntsiab zoo muaj xws li:
1. Super muaj zog corrosion kuj
Silicon carbide muaj kev tiv thaiv zoo heev rau cov xov xwm corrosive xws li kua qaub, alkali, thiab ntsev, thiab nws lub neej kev pab cuam deb tshaj cov hlau thiab yas nozzles.
2. Zoo heev hnav tsis kam
Txawm hais tias cov slurry muaj cov khoom me me, cov silicon carbide nozzle tuaj yeem tswj cov kev ua haujlwm ruaj khov rau lub sijhawm ntev thiab tsis yooj yim hloov hauv lub kaum sab xis vim hnav.
3. Kev kub siab ua haujlwm zoo
Nyob rau hauv qhov kub-kub flue gas ib puag ncig, silicon carbide nozzles yuav tsis deform los yog soften, kom ntseeg tau ruaj khov tshuaj tsuag.
4. Zoo thermal conductivity
Pab lub nozzle kom dissipate tshav kub sai thiab txo thermal kev nyuaj siab puas.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm silicon carbide nozzle
Lub silicon carbide desulfurization nozzle atomizes desulfurization slurry (feem ntau limestone slurry) rau hauv me me tee, uas nkag mus rau hauv tag nrho kev sib cuag nrog cov flue gas, ua rau cov alkaline tshuaj nyob rau hauv lub slurry reacts chemically nrog sulfur dioxide nyob rau hauv flue gas, yog li ua tiav lub hom phiaj ntawm desulfurization.
Tus tsim thiab cov khoom ntawm lub nozzle ncaj qha cuam tshuam rau cov nyhuv atomization:
-Qhov zoo dua cov atomized hais, qhov loj ntawm qhov chaw sib cuag, thiab ntau dua qhov desulfurization efficiency
-Cov khoom siv silicon carbide ua kom muaj kev ruaj ntseg ntev ntawm lub nozzle aperture, zam kev txo qis hauv atomization nyhuv vim hnav thiab tsim kua muag
Daim ntawv thov scenarios
Silicon carbide desulfurization nozzles yog dav siv hauv:
- Thermal fais fab nroj tsuag
- Hlau cog
- Cov khib nyiab incineration cog
-Lwm cov kev lag luam uas xav tau cov roj flue desulfurization
Cov lus qhia txog kev tu txhua hnub
Txawm hais tias silicon carbide nozzles muaj lub zog ruaj khov, kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua tseem tseem ceeb:
- Tsis tu ncua xyuas seb lub nozzle puas raug thaiv lossis hnav
-Tau qhov kev ua haujlwm zoo ntawm slurry filtration system
-Hloov lub nozzle tam sim ntawd thaum pom qhov txo qis hauv kev ua haujlwm
Cov ntsiab lus
Txawm hais tias silicon carbide desulfurization nozzle tsuas yog ib feem me me hauv 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 zoo tshaj plaws rau ntau thiab ntau lub lag luam vim nws zoo heev corrosion kuj, hnav tsis kam, thiab kub tsis kam.
Xaiv cov khoom siv nozzle tsim nyog thiab tsim tsis tau tsuas yog txhim kho ib puag ncig ntsuas, tab sis kuj coj cov txiaj ntsig kev lag luam mus sij hawm ntev rau kev lag luam. Nyob rau niaj hnub no qhov kev xav tau ntawm ib puag ncig nruj zuj zus, silicon carbide desulfurization nozzles ntsiag to tiv thaiv peb lub ntuj xiav.
