Hauv cov cuab yeej tiv thaiv ib puag ncig, muaj qhov zoo li tsis pom tseeb tab sis tseem ceeb heev - lub desulfurization nozzle. Nws txoj hauj lwm yog kom sib npaug ntawm cov tshuaj desulfurization slurry rau hauv cov roj flue los pab tshem tawm cov teeb meem sulfur dioxide. Niaj hnub no, cia peb tham txog lub siab-Kev ua haujlwm desulfurization nozzle khoom - silicon carbide.
Dab tsi yog silicon carbide?
Silicon carbide yog ib qho khoom siv hluav taws xob ua kom tsis muaj zog uas tsim los ntawm silicon thiab carbon ntsiab lus. Nws cov yam ntxwv yog:
High hardness, thib ob tsuas yog pob zeb diamond
Kub kub kuj, muaj peev xwm tswj tau stability nyob rau hauv huab cua kub
Acid thiab alkali corrosion kuj, tiv thaiv cov tshuaj lom neeg hauv desulfurization ib puag ncig
Zoo thermal conductivity, tsis yooj yim tawg vim qhov kub hloov pauv
Vim li cas thiaj xaiv silicon carbide rau desulfurization nozzles?
Qhov ib puag ncig desulfurization yog 'kev sim hnyav' rau nozzles:
High flue gas kub thiab muaj zog corrosiveness
Lub slurry muaj cov khoom siv uas muaj qhov hnyav thiab ua rau cov khoom siv
Silicon carbide cov ntaub ntawv zoo kawg nkaus muaj peev xwm daws cov teeb meem no:
Corrosion tsis kam ua kom lub sijhawm ua haujlwm ruaj khov ntawm lub nozzle
High hardness thiab hnav tsis kam ua kom ntev lub neej kev pab cuam
Zoo thermal conductivity tsis txhob tawg los ntawm thermal stress
Qhov zoo ntawm silicon carbide desulfurization nozzle
1. Lub neej ua haujlwm ntev - txo qhov hloov zaus thiab txo tus nqi kho
2. Kev ua haujlwm ruaj khov - cov nyhuv tshuaj tsuag tuaj yeem khaws cia txawm tias nyob hauv ib puag ncig hnyav
3. Ua tau zoo desulfurization - cov tshuaj tsuag zoo ib yam los txhim kho desulfurization efficiency
4. Kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob - txo qis qis thiab txo nqi khiav haujlwm
Yuav ua li cas xaiv ib tug haum silicon carbide nozzle?
Thaum xaiv, cov ntsiab lus tseem ceeb yog:
Txau lub kaum sab xis thiab ntws ntawm nozzle
Siv tau qhov kub thiab txias ntau yam
Compatibility nrog desulfurization systems uas twb muaj lawm
Chaw tsim tshuaj paus kev txhawb nqa thiab kev pab cuam tom qab muag
Txawm hais tias silicon carbide desulfurization nozzle tsuas yog ib qho me me hauv cov kab ke desulfurization, nws qhov kev ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ruaj ntseg ntawm tag nrho cov kab ke. Xaiv qhov zoo tshaj plaws silicon carbide nozzles yog muab koj cov khoom tiv thaiv ib puag ncig nrog "vanguard".
