Qhov loj tshaj plaws cov tshuaj tiv thaiv bonded silicon carbide Flue Gas Desulphurization Spray nozzle Hoobkas thiab chaw tsim tshuaj paus nyob rau hauv Suav teb
Flue Gas Desulfurization (FGD) Absorber Nozzles
Kev tshem tawm cov sulfur oxides (SOx) yog qhov tshwm sim los ntawm cov pa pa uas siv cov alkali reagent, xws li cov limestone ntub dej slurry.
Thaum cov fossil fuels tau siv rau hauv cov txheej txheem combustion los khiav boilers, furnaces, lossis lwm yam khoom siv uas tuaj yeem tso tawm SO2 lossis SO3 ua ib feem ntawm cov pa pa. Cov sulfur oxides no tau yooj yim nrog lwm cov ntsiab lus tsim teeb meem xws li sulfuric acid thiab muaj peev xwm ua rau tib neeg noj qab haus huv thiab ib puag ncig. Vim muaj cov teebmeem no, qhov kev tswj xyuas qhov sib xyaw ua ke hauv cov pa hluav taws xob yog qhov tseem ceeb ntawm cov hluav taws xob hluav taws xob hluav taws xob thiab lwm yam kev siv hluav taws xob.
Vim yog kev yaig, ntsaws ruaj ruaj, thiab muaj kev txhawj xeeb, ib qho ntawm cov kev txhim khu kev qha tshaj plaws los tswj cov emissions yog ib qho kev qhib-ntsev ntub dej desulfurization (FGD) txheej txheem siv limestone, hydrated txiv qaub, dej hiav txwv, los yog lwm yam alkaline tov. Cov tshuaj tsuag nozzles muaj peev xwm ua tau zoo thiab ntseeg tau faib cov slurries mus rau hauv cov kav dej nqus. Los ntawm kev tsim cov qauv zoo ib yam ntawm cov tee me me, cov nozzles muaj peev xwm tsim tau qhov chaw zoo tsim nyog rau kev nqus kom zoo thaum txo qis kev nkag ntawm cov tshuaj txhuam rau hauv cov pa roj.
Xaiv lub FGD Absorber Nozzle:
Yam tseem ceeb uas yuav tau xav txog:
Tshem tawm cov xov xwm ceev thiab viscosity
Yuav tsum tau droplet loj
Qhov loj me me droplet yog qhov tseem ceeb los xyuas kom meej qhov nqus tau zoo
Cov khoom siv nozzle
Raws li cov roj flue feem ntau corrosive thiab cov kua dej txhuam feem ntau yog cov slurry nrog cov ntsiab lus siab thiab cov khoom abrasive, xaiv qhov tsim nyog corrosion thiab hnav cov khoom tiv thaiv yog qhov tseem ceeb.
Nozzle clog kuj
Raws li cov kua dej txhuam feem ntau yog cov slurry nrog cov ntsiab lus siab, kev xaiv ntawm lub nozzle hais txog qhov txhaws tsis kam yog qhov tseem ceeb.
Nozzle spray qauv thiab tso
Txhawm rau kom ua tiav qhov kev nqus tau zoo ntawm cov roj ntws uas tsis muaj bypass thiab lub sijhawm nyob txaus yog qhov tseem ceeb.
Nozzle txuas qhov loj thiab hom
Yuav tsum tau txhuam cov kua dej ntws
Muaj kev poob siab (∆P) hla lub nozzle
∆P = muab siab ntawm nozzle inlet - txheej txheem siab sab nraum nozzle
Peb cov kws tshaj lij engineers tuaj yeem pab txiav txim siab seb lub nozzle yuav ua raws li qhov xav tau nrog koj cov ntsiab lus tsim
Common FGD Absorber Nozzle Siv thiab Kev Lag Luam:
Thee thiab lwm yam fossil roj fais fab nroj tsuag
Petroleum refineries
Municipal khib nyiab incinerators
Cement kilns
Hlau smelters
Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd yog ib qhov loj tshaj plaws silicon carbide ceramic cov ntaub ntawv tshiab daws teeb meem hauv Suav teb. SiC technical ceramic: Moh lub hardness yog 9 (New Moh's hardness yog 13), nrog zoo heev tiv taus yaig thiab corrosion, zoo heev abrasion - kuj thiab anti-oxidation. SiC khoom lub neej kev pab cuam yog 4 mus rau 5 zaug ntev dua 92% alumina khoom. MOR ntawm RBSiC yog 5 mus rau 7 npaug ntawm SNBSC, nws tuaj yeem siv rau cov duab ntau dua. Cov txheej txheem hais lus yog ceev, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob. Peb ib txwm pheej sim sim peb lub hom phiaj thiab muab peb lub siab rov qab los rau zej zog.
