Cov cuab yeej tseem ceeb uas nquag siv hauv lub cev desulfurization yog cov cuab yeej tseem ceeb xws li nqus ntauwd, flue, chimney, desulfurization twj tso kua mis, supercharged kiv cua, thiab lub zog tiv thaiv corrosion ntawm lub twj tso kua mis desulfurization, nqus ntauwd, flue, chimney thiab lwm yam. Tam sim no tau piav qhia.
Kev siv ntauwd nqus thiab chimney
ntub flue roj desulfurization ib puag ncig tiv thaiv technology (FGD) vim nws siab desulfurization tus nqi, dav siv thee siv, txheej txheem technology matures, ntev-sawv, hloov me me load, siab flue gas kev kho mob muaj peev xwm, thiab lwm yam, yog dav siv nyob rau hauv txhua qhov loj, nruab nrab-qhov loj me thermal fais fab nroj tsuag, dhau los ua cov txheej txheem tseem ceeb ntawm cov pa roj desulfurization hauv tsev thiab sab nraud thermal fais fab nroj tsuag. Txawm li cas los xij, cov txheej txheem kuj tseem muaj zog hauv corrosion, thiab kev kho mob ntawm flue gas kub, SO2 absorbent kua cov ntsiab lus, muaj zog hnav tsis kam, cov khoom loj, cov kev xav tau zoo, kev xav tau zoo, kev tiv thaiv corrosion tsis ua haujlwm. Yog li ntawd, kev tswj corrosion ntawm lub cuab yeej yeej ib txwm yog ib qho ntawm cov teeb meem tseem ceeb uas cuam tshuam rau lub sijhawm ntev ntawm lub cuab yeej.
Cov dej ntws ntub dej desulfurization nqus ntauwd, kev xaiv ntawm chimney puab cylindrical corrosion khoom yuav tsum xav txog cov hauv qab no:
(1) Ua tau raws li qhov yuav tsum tau ua ntawm corrosion nyob rau hauv cov tshuaj nyuaj: cov tshuaj ib puag ncig nyob rau hauv lub chimney yog complex, cov pa luam yeeb muaj cov kua qaub ntau, thiab cov condensate tsim nyob rau saum npoo ntawm lub puab hauv ob sab phlu yog muaj zog rau feem ntau cov ntaub ntawv hauv tsev. Yog li ntawd, cov khoom siv hauv ob sab phlu yuav tsum muaj zog acid corrosion kuj;
(2) Kev ntsuas kub: qhov kub ntawm qhov sib txawv ntawm cov roj flue yog qhov loj, qhov kub ntawm cov roj flue tom qab ntub dej desulfurization yog nruab nrab ntawm 40 ° C mus rau 80 ° C, nyob rau hauv kev saib xyuas ntawm lub desulfurization system los yog tsis ua hauj lwm, cov pa taws kub nyob rau hauv lub chimney yog nyob rau hauv lub txij nkawm ntawm lub desulfurization system. lub chimney Nyob nruab nrab ntawm 130 degree C ~ 150 degree C, lub liner yuav tsum muaj ib tug tsis kam mus rau qhov kub thiab txias sib txawv, uas yuav tsis tawg thiab check thaum lub sij hawm ib tug heev kub hloov;
(3) Kev hnav tsis kam: Cov pa roj flue muaj cov hmoov av ntau, thiab tib lub sijhawm nyob rau hauv qhov kev txiav txim ntawm corrosive media, qhov tseeb ntawm hnav yuav pom tseeb dua, yog li cov khoom siv tiv thaiv corrosion yuav tsum tau hnav zoo. tsis kam;
(4) Muaj qee qhov kev tiv thaiv kev ua haujlwm zoo: Txij li qee qhov chimneys, suav nrog cov lus tsa suab, seismic thiab cua los ntawm lub ntiaj teb nws tus kheej, lub chimney, tshwj xeeb tshaj yog qhov siab-siab, lub kaum sab xis yuav tshwm sim los yog deviate, thaum lub chimney ib txhia Kev tswj tsis tau cov tshuab ua haujlwm tuaj yeem tshwm sim thaum lub sijhawm teeb tsa thiab kev thauj mus los, yog li cov khoom siv los tiv thaiv corrosion yuav tsum muaj qee yam kev ua haujlwm dabtsi yog khoov;
(5) muaj lub zog sib txuas zoo: cov khoom siv los tiv thaiv corrosion yuav tsum muaj lub zog ruaj khov, tsis yog tsuas yog hais txog kev sib raug zoo ntawm cov khoom siv, tab sis kuj muaj kev sib raug zoo siab ntawm cov khoom thiab cov khoom siv substrate, thaum cov khoom tsis yog yooj yim. Cracking, hierarchical lossis tev, adhesion, thiab cuam tshuam lub zog, yog li ua kom zoo dua corrosion kuj. Feem ntau peb xav tau lub zog sib txuas ntawm cov khoom tseem ceeb thiab cov qauv hlau kom tsawg kawg yog 10MPa
