Hebei Qingda Ib puag ncig tiv thaiv Machinery Co., Ltd. Yog tias koj yuav mus rau cov lag luam wholesale zoo ntub dej flue roj desulfurization khoom ua nyob rau hauv Suav teb, txais tos kom tau txais cov ntaub ntawv ntau ntxiv los ntawm peb lub hoobkas.
Hom loj
Cov roj ntub dej desulfurization tshuab tuaj yeem raug cais raws li cov khoom nqus thiab cov txheej txheem siv. Cov hom muaj xws li:
Limestone-Gypsum Wet Flue Gas Desulfurization
Ammonia-Based Flue Gas Desulfurization
Magnesium-Based Flue Gas Desulfurization
Ntawm cov thev naus laus zis no, limestone-gypsum ntub dej flue roj desulfurization yog ib qho ntawm cov txheej txheem siv dav tshaj plaws rau cov ntawv thov loj -.
Cov khoom siv tseem ceeb
Ib qho kev ntub dej flue gas desulfurization system muaj cov hauv qab no tseem ceeb:
1. Desulfurization Ntauwd (Absorber)
Lub absorber yog qhov tseem ceeb ntawm cov dej ntub dej FGD. Nws muab kev sib cuag txaus ntawm cov roj flue thiab nqus slurry, tso cai rau SO₂ absorbed thiab tshuaj hloov dua siab tshiab.
2. Kev Npaj Kev Npaj thiab Kev Pabcuam Absorbent
Qhov no system npaj, khw muag khoom, thiab thauj cov absorbent. Rau limestone-gypsum FGD systems, nws feem ntau suav nrog limestone tuav, sib tsoo, slurry npaj, cia, thiab khoom siv.
3. Flue Gas System
Flue gas system muaj xws li flue gas inlet thiab qhov hluav taws xob ducts, dampers, thiab lwm yam khoom siv. Nws yog lub luag haujlwm rau kev coj cov roj flue rau hauv thiab tawm ntawm qhov system desulfurization.
4. Oxidation Cua System
Lub tshuab oxidation cua muab cua rau lub absorber los txhawb cov oxidation ntawm sulfite rau hauv sulfate thiab pab gypsum tsim nyob rau hauv limestone-gypsum FGD systems.
5. Gypsum Dewatering thiab Los ntawm -cov khoom tuav System
Qhov no cais thiab dewaters lub gypsum slurry generated thaum lub sij hawm desulfurization txheej txheem. Cov gypsum rov qab tuaj yeem siv tau ntxiv nyob ntawm nws qhov zoo thiab qhov xav tau hauv zos.
6. Kev kho dej khib nyiab
Kev kho dej khib nyiab yog siv los tswj thiab kho cov txheej txheem dej khib nyiab uas tsim los ntawm FGD ntub dej ua ntej tso tawm lossis rov siv dua.
01
Flue Gas Contact
Tom qab tawm hauv cov khoom siv combustion, cov roj flue nkag mus rau hauv ntauwd desulfurization, los yog absorber. Nyob rau hauv lub pej thuam, cov pa roj flue tuaj rau hauv kev sib cuag nrog cov tshuaj pleev xim zoo nkauj, tsim kom muaj cov pa loj -kua qhov chaw sib cuag uas txhawb nqa qhov nqus ntawm SO₂.
02
Absorbent Circulation
Lub absorbent feem ntau yog alkaline slurry, xws li limestone slurry, uas yog npaj los ntawm kev sib xyaw limestone nrog dej. Lub slurry yog txuas ntxiv mus thiab txau los ntawm lub absorber kom muaj kev sib cuag txaus nrog cov roj flue. Thaum lub sij hawm tus txheej txheem no, SO₂ yog absorbed rau hauv cov kua theem thiab reacts nrog alkaline absorbent.
03
Oxidation thiab kev hloov pauv
Lub absorbed sulfur dioxide pib tsim sulfite thiab bisulfite hom. Cua los yog oxygen yog nkag mus rau hauv lub absorber los txhawb oxidation, converting cov sulfite rau hauv sulfate. Hauv limestone-gypsum ntub dej FGD systems, cov sulfate ces reacts nrog calcium ions los ua calcium sulfate dihydrate (gypsum).
04
Los ntawm -Kev kho cov khoom
Cov txiaj ntsig desulfurization slurry tau ua tiav los cais thiab dewater cov khoom los ntawm - khoom. Hauv limestone-gypsum systems, gypsum tuaj yeem rov qab los rau kev siv ntxiv, thaum cov dej khib nyiab thiab lwm cov txheej txheem kwj dej raug kho raws li cov kev cai ib puag ncig.
Cov cheeb tsam thov
Wet flue gas desulfurization khoom siv dav siv hauv kev lag luam nrog SO₂ emissions tseem ceeb, suav nrog:
Coal-cov chaw tsim hluav taws xob tua hluav taws
Muaj boilers
Steel mills
Cement nroj tsuag
Coking nroj tsuag
Cov nroj tsuag tshuaj
Tau txais kev daws teeb meem
Cov tshuab no tuaj yeem txo cov sulfur dioxide emissions los ntawm cov pa hluav taws xob ua lag luam thiab pab cov chaw ua raws li cov qauv siv huab cua emissions thaum txhim kho tag nrho ib puag ncig kev ua haujlwm.
