FGD twj tso kua mis yog cov khoom siv flue roj desulfurization hauv kev lag luam xws li cov nroj tsuag hluav taws xob thiab steel smeeb. Lawv txoj kev ntseeg tau ncaj qha ncaj qha cuam tshuam desulfurization tswj tau nthuav dav ntxiv thiab kev ua kom muaj kev ua tau zoo los ntawm kev tswj hwm kev ua haujlwm kom tswj ruaj khov thoob plaws nws lub neej tag nrho. Cov kab lus no qhia cov ntsiab lus tseem ceeb thiab siv cov tshuab hluav taws xob zoo los ntawm plaub qhov kev xav tau, kev tsim khoom, kev sim thev naus laus zis, thiab ua haujlwm tau zoo.
Ⅰ. Kev Ntsuas Kev Mob Corrosion Kuj thiab Cov Khoom Siv Hauv Cov Khoom Xaiv
FGD twj muaj nyob rau hauv ib puag ncig ib puag ncig ntawm kev ua kom muaj zog (chloride ion ntau dua ( Cov ntsiab lus tso nruj rau cov kev ua tau zoo ntawm cov ntaub ntawv siv hauv kev ntws hauv txoj kev sib tw. Cov ntaub ntawv ib txwm muaj xws li cov khoom siv nrum hlau lossis cov roj carbon hlau muaj kev cuam tshuam nrog pitting corrosion hauv chloride ib puag ncig. Thaum 304 stainless hlau muaj zoo corrosion tsis kam, nws tsis muaj hnav tsis kam. Yog li no, niaj hnub desulfurization twj tso kua mis feem ntau yog siv cov kab li cas ntawm cov hlau uas muaj zog (xws li ultra-siab molecular hnyav polyethylene (UHMWPE).
Cov kauj ruam tseem ceeb hauv kev tswj hwm tau zoo yog cov khoom siv tshuaj xyuas cov khoom lag luam (ov Rau cov ntaub ntawv yas rau hauv lub zog nrog lub substrate (shear lub zog ntau dua los yog sib luag rau 5mpa) thiab thermal nthuav kev sib raug zoo yuav tsum tau lees paub kom tiv thaiv kev ua haujlwm. Ib lub zog cog ib zaug yuav 2205 duplex stainless hlau nrog lub chromium cov ntsiab lus 2% hauv qab tus qauv. Qhov no ua rau muaj kev txhim kho corroosular ntawm lub twj tso kua mis thaum muaj rau lub hlis ua haujlwm. Kev tsom xam spectroscopic thaum kawg traced qhov ua rau muaj kev mob siab ntau thaum tseem ceeb ntawm cov khoom siv sib xyaw ua ke.
Ii. Kev Tsim Kho Cov Txheej Txheem Kev Tsim Kho thiab Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv
Cov khoom lag luam tseem ceeb rau cov twj kav dej suav nrog tus neeg siv lub cev tso hluav taws xob, tso lub cev tso hluav taws xob, thiab lub rauv hluav taws xob vuam. Txhua cov txheej txheem kev sib cav tuaj yeem ua rau muaj kev ntxhov siab thiab ntws tawm hauv txoj kev distortion. Raws li ib tug tseem ceeb txaus -} Cov kab mob sib kis no, tus impeller cov hniav profile ncaj qha cuam tshuam cov hydraulic ua tau zoo thiab cavitation kev ua tau zoo. Tus qauv tsim nyog yuav tsum muaj cov hniav inlet ntug tuab mus rau tsawg dua los yog sib npaug rau 0.1mm thiab qhov hluav taws xob lub kaum ntse ntse ntawm tsawg dua lossis sib npaug rau ± 0.5 degree. Cov txheej txheem casting siv cov sillica sol precision casting txheej txheem xws li qhov tsis xws luag sab hauv tsawg dua lossis sib npaug rau φ1mm).
Qhov zoo ntawm cov twj tso kua mis lub cev vuam yog hais txog cov txheej txheem muaj zog. Lub siab - bearing weldsel ntawm lub pob zeb nruab nrab ntawm kev sib tw ntawm Argon arc vuam (ATG) rau kev ua haujlwm ntawm cov qauv sib tw thiab cov qauv hlau arc vuam. Lub interpass kub yog nruj me ntsis tswj (tsawg dua los yog sib npaug ntawm 150 degree) los tiv thaiv kev tawg thermal. Tom qab vuam yog ua tiav, 100% ultrasonic qhov khuam kom pom kom meej (UT, raws li JB / T 4730 qib I) thiab kev kuaj pom npoo me) yuav tsum ua. Cov kev tshawb xyuas muaj zog zoo yuav tsum tau siv los xyuas qhov kev faib tawm Weld kev ntxhov siab ntau dua lossis sib npaug ntawm 70% ntawm cov khoom siv tau tawm los lub zog). Cov chaw tsim khoom muaj kev sib tsoo qeeb thiab xau dej thaum lub sijhawm ua haujlwm vim tias preheating tsis txaus ntawm lub twj tso kua mis lub cev WELD. Qhov teeb meem no tau daws tau zoo los ntawm kev nce qib preheat rau 200- 250} nrog post-kub dehydrogenation kev kho mob (200-300℃rau 2 teev).
III. Multi - diteal pov thawj ntawm tag nrho- kev tshuaj xyuas cov txheej txheem
Kev tswj kom zoo ntawm cov twj desulfurization yuav tsum tau peb {{-}}}}}}} م khoom siv, cov khoom siv, thiab tag nrho cov khoom siv. Ntxiv rau cov khoom siv tshuaj lom neeg ua haujlwm thiab cov cuab yeej siv rau cov khoom siv tseem ceeb ntawm cov hlau uas tsis muaj duab ntau ntxiv yuav tsum yog 50:50 ± 10%). Kev tshuaj xyuas tivthaiv tiv thaiv kom pom ntawm qhov tseeb (piv txwv li cov neeg siv hluav taws xob tsawg dua lossis muaj kev sib luag ntawm 1.5 npaug ntawm 1.5 npaug ntawm 1.5 zaug tus qauv tsim rau 30 feeb yam tsis muaj xau). Tiav Lub Cav Kev Xeem Qhia suav nrog kev txheeb xyuas nkhaus (ntws { degree). Ntawm cov ntaub ntawv tshwj xeeb, cov kev ua haujlwm tshwj xeeb ntawm kev ua haujlwm ntawm slurry coj los ntawm cov kev yuav tsum tau ua (thov nyiaj ntawm ib sab) thiab kev ua haujlwm ntawm ib sab) thiab kev ntsuas nyiaj ntawm ib sab) thiab cov tshuaj lis haujlwm ntawm ib sab Kev soj ntsuam rau 72 teev rau qhov tsis muaj kev loj hlob tawg). Lub npe nrov thoob ntiaj teb cov chaw tsim tshuaj paus, los ntawm kev qhia txog cov pa hluav taws xob, cov kev ntxhov siab ua haujlwm hauv ntau yam kev ua haujlwm hauv ntau yam hauv 30% thiab txo cov kev ua haujlwm tsis ua haujlwm los ntawm 42%.
IV. Kev tswj kom zoo dua qub rau kev ua haujlwm thiab txij nkawm hloov tau
Kev tswj kom zoo ntawm cov twj desulfurization yuav tsum tsis txhob txwv rau kev ua haujlwm Hoobkas tab sis kuj yuav ua haujlwm rau kev ua haujlwm ntev ntev li ntev {} lub sijhawm ua haujlwm. Nws raug nquahu kom tsim ib qho kev kaw- lub voj archivate Cov khoom siv Archive cov ntaub ntawv tag nrho cov ntaub ntawv, suav nrog cov khoom siv cov khoom siv, cov ntaub ntawv vuam, thiab cov ntaub ntawv xeem. Cov ntsuas tshuaj xyuas online no suav cov tsis muaj xws li kev co (Accelerometer), thiab siab (ntau zaus (kev sib tw sab hauv lub nplhaib puas yog 2-3 zaug lub zog tig). Ib qho kev soj ntsuam disassembly tau ua txhua 2000 teev rau kev ntsuas kev sib txawv tsawg dua los yog sib npaug ntawm 10%), thiab cov roj hmab ua kom qis dua lossis sib npaug rau 15%).
Lub tuam txhab hlau loj tau ua kom pom tias los ntawm kev ua haujlwm desulffurization thiab kev kho cov ntaub ntawv tsis muaj peev xwm ua tau 3 {}} 6 lub hlis ua ntej. Piv txwv li, cov khaub ncaws tsis zoo siab yuav tsum tau rov qab mus rau cov khoom ntawm cov khoom noj uas siab, ua rau txo cov khoom siv tsis kam. Qhov no tso cai rau kev tsim kho kom haum rau cov khoom xaiv thiab cov txheej txheem tsis zoo rau cov kab txuas ntxiv. Qhov "tsim khoom {{{- kev siv cov khoom siv lub neej (lub sijhawm ua tau zoo ntawm kev poob qis ntawm 8,000 teev mus rau 15,000 teev).
Tag
Kev tswj hwm zoo ntawm Flue Gas Desulfurization twj yog ib txoj haujlwm zoo tshaj plaws uas muaj kev cuam tshuam nrog cov ntaub ntawv kev tshawb fawb, kev tshawb xyuas tshuab, thiab kev tswj hwm thiab kev tswj hwm kev lag luam. Tsuas yog los ntawm nruj me ntsis cov khoom siv, ua kom zoo dua kev tsim kho thiab kho cov haujlwm ntev tshaj plaws hauv kev ua haujlwm dhau los. Nrog kev hloov kho txuas ntxiv ntawm cov qauv kev tiv thaiv ib puag ncig thiab kev txhim kho cov twj desulfurization, kev tswj hwm zoo zuj zus mus hloov digitalization thiab kev kwv yees. Los ntawm kev sib txuas cov ntaub ntawv loj tsom xam nrog cov kev lag luam ua kom tau kev hloov pauv rau cov khoom siv ntsuab "rau" kev tiv thaiv cov roj ntsha kev hloov pauv ntawm cov khoom lag luam.
