Flue Gas Desulfurization
Qhia luv luv ntawm Semi-dry Desulfurization Technology rau Sintering Rauv Flue Gas hauv Hlau thiab Hlau Kev Lag Luam
Xyoo 1986, Wuxi Linzhou Kom Qhuav Khoom Co., Ltd, ua haujlwm loj ntawm kev tshawb fawb hluav taws xob ua haujlwm, ua ke ntawm Southwest hluav taws xob thev naus laus zis "hauv National" lub xya xyoo Kev npaj "kev tiv thaiv ib puag ncig kev tshawb fawb thiab thev naus laus zis kev tshawb fawb project.Tom qab ob peb xyoos ntawm kev tshawb fawb, ua tiav cov khoom siv hauv Suav teb tau teeb tsa hauv Sichuan Baima Fais Fab thiab cov kev ntsuas ua ntej tau ua tiav tiav, ua rau qhov kev tshawb fawb thev naus laus zis no ua ib kauj ruam loj rau kev lag luam.Qhov kev kawm dhau los ntawm kev soj ntsuam kev lag luam los ntawm Lub Xeev Lub Tsev Haujlwm Saib Xyuas Zog hauv 1990 thiab yeej qhov khoom plig thib ob.
Nyob rau hauv 1998, semi-dry flue roj desulfurization tshuab tau teev raws li ib qho ntawm cov ntsiab lus ntawm localization. Wuxi linzhou tshuab ziab khaub ncaws co., ltd, koom tes nrog lub koom haum sab hnub poob hluav taws xob hluav taws xob tsim hluav taws xob, Nanjing lub koom haum kev lag luam hav zoov thiab tshuaj lom neeg, Chongqing tsev kawm ntawv thiab lwm lub tsev tshawb fawb tshawb fawb, tau ua qhov project ntawm "kev sim kev lag luam thiab kev tshawb fawb ntawm cov khoom siv hluav taws xob ib nrab qhuav desulfurization". daim ntawv cog lus tus naj npawb yog SPKJ005-02 thiab qhov project code naj npawb yog j-16ikj98.The kho flue gas ntim yog 400,000 Nm3 / h.Wuxi linzhou drying khoom co., ltd. yog lub luag haujlwm tseem ceeb rau lub luag haujlwm tseem ceeb ntawm qhov project: high-speed centrifugal atomizing chav tsev nrog 45 tons ntawm cov kua tshuaj tsuag ib teev.Tom qab kev sim ua tiav, nws tau muab tso rau hauv kev ua haujlwm hauv Guizhou Chuanheng Chemical Co., Ltd. hauv 2005. Lub tshuab auxiliary muaj lub zog ntawm 312KW thiab cov tshuaj tsuag ntau tshaj plaws / h 50. Cov cuab yeej ua haujlwm ntawm lub peev xwm tag nrho txhua xyoo nrog cov hmoov qhuav qhuav txhua hnub ntawm 600 tons. Txog rau tam sim no, ntau pawg tau muab tso rau hauv kev lag luam hauv kev lag luam tshuaj lom neeg loj. Cov chav ua haujlwm tsis tu ncua txhua xyoo nrog kev ua haujlwm ruaj khov thiab txhim khu kev qha khoom ruaj ntseg.
Thaum lub 45T / h centrifugal atomizing chav tsev yog tsim thiab tsim, cov kev tshawb fawb thiab kev loj hlob pab neeg kuj tau ua kev tshawb fawb ntawm cov qauv tsim ntawm lub semi-dry desulfurization ntauwd, lub flow field tsom xam nyob rau hauv lub desulfurization ntauwd thiab particle teb. Pab pawg tshawb fawb thiab kev tsim kho kuj tau tsim los ntsuas thiab txheeb xyuas cov khoom siv los ntawm Denmark's NIRO Company, thiab tau qhia txog cov software tsim nyog rau kev tsim cov cua kub distributor thiab desulfurization ntauwd ntawm NIRO Company.Nws tau koom nrog kev sib tw ntawm 125MW units hauv Zhejiang Qian Qing Power Plant 0M hauv 125MW thiab 125MW hauv Zhejiang Qian Qing Yutan Power Plant. semi-dry desulfurization tej yaam num. Kev txiav txim los ntawm qhov teeb meem kev sib tw, nws muaj txiaj ntsig zoo ntawm tus nqi, tab sis nws tau raug tsis lees paub vim tsis muaj kev lag luam. Yog li ntawd, tau ntau xyoo, feem ntau ntawm cov txheej txheem ib nrab qhuav desulfurization siv nyob rau hauv domestic fais fab nroj tsuag yog cov khoom siv los ntawm txawv teb chaws.
Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ntawm lub teb chaws ib puag ncig tiv thaiv kev cai, lub flue roj desulfurization ntawm sintering rauv nyob rau hauv steel mills, raws li ib tug tseem ceeb lub teb chaws tswj lub hom phiaj tom qab lub flue roj desulfurization ntawm fais fab nroj tsuag, accounted rau txog 11% ntawm lub teb chaws emissions ntawm SO2 thiab lwm yam atmospheric pollutants nyob rau hauv steel kev lag luam tsuas yog lub hwj chim ranking, thib ob. SO2, CO2 thiab lwm yam kuab paug tsim nyob rau hauv cov txheej txheem sintering account rau 40% ~ 60% ntawm txhua xyoo emissions ntawm hlau thiab steel kev lag luam.Yog li ntawd, nws yog ib qho tseem ceeb heev rau txoj kev loj hlob ntawm cov hlau thiab steel kev lag luam thiab kev txhim kho ntawm ecological ib puag ncig los tswj cov pa paug ntawm sintering flue technology thiab transforming flue technology. desulfurization.
Xa mus rau ntau tshaj 10 tus neeg siv ntawm sintering flue roj desulfurization txheej txheem thiab kaum ob ntawm desulfurization txheej txheem tsim chav xws li Shougang, Jinan, Baosteel thiab Tangshan, tshuaj tsuag ziab ib nrab qhuav sintering flue roj desulfurization txheej txheem yog dav siv. Cov txheej txheem tshuaj tsuag kom qhuav semi-dry desulfurization muaj cov yam ntxwv ntawm cov cuab yeej paub tab, cov txheej txheem yooj yim ntws, kev ntseeg siab thiab lwm yam. Tus nqi desulfurization tuaj yeem ncav cuag ntau dua 85%, SO2 emission concentration tom qab desulfurization ≤100mg / Nm3, thiab plua plav emission concentration ≤50mg / Nm3..Cov txheej txheem muaj qee qhov kev thov ntau (8%) hauv Tebchaws Meskas thiab qee lub tebchaws Europe sab hnub poob.Desulfurized tshauv tuaj yeem siv ua cement additive, gypsum thiab lwm yam.
Nyob rau hauv xyoo tas los no, Wuxi Linzhou Drying Equipment Co., Ltd. tau koom tes tsim kev txhim kho kev tshawb fawb ntawm flue gas desulfurization ntawm sintering tshuab hauv steel mills nrog Nanjing Forest Products Chemical Research Institute, Jinan Iron thiab Steel Group, Dalian University of technology thiab lwm lub tsev kawm ntawv:
Ua ke nrog Dalian University of Technology, ib qho kev cog qoob loo rau cov pa roj desulfurization hauv sintering rauv tau tsim nyob rau hauv Chongqing Hlau thiab Steel Group.
Lub desulfurization ntauwd tsim ntawm 320m2 sintering tshuab desulfurization project ntawm Jinan hlau thiab steel pawg co., ltd. thiab kev ntsuam xyuas hauv tsev ntawm lub tsev 45-tuj atomizing tau ua tiav cov txiaj ntsig zoo ntawm kev hloov ntawm cov khoom siv hauv tsev thiab cov khoom siv txawv teb chaws.
