Daim ntawv thov Case ntawm Thermal Power Plant hauv Shanghai

Shanghai Certain Thermal Power Co., Ltd. ua haujlwm nyob rau hauv kev lag luam uas suav nrog kev tsim khoom thiab muag khoom ntawm thermal zog, kev txhim kho cov thev naus laus zis thev naus laus zis thev naus laus zis, thiab kev siv dav dav ntawm cov tshauv ya. Lub tuam txhab tam sim no ua haujlwm peb lub tshuab hluav taws xob hluav taws xob hluav taws xob nrog lub peev xwm ntawm 130 tons hauv ib teev thiab peb lub tshuab hluav taws xob rov qab-siab turbine generator teeb nrog tag nrho cov peev txheej ntawm 33 MW. Nws muab cov khoom siv huv, ib puag ncig tus phooj ywg, thiab cov chav ua haujlwm zoo rau ntau tshaj 140 cov neeg siv khoom siv nyob hauv thaj chaw xws li Jinshan Industrial Zone, Tinglin Industrial Zone, thiab Caojing Chemical Zone. Cov hluav taws xob faib hluav taws xob sib kis tau tshaj 40 mais, ua tau raws li qhov xav tau cua sov ntawm Jinshan Industrial Zone thiab thaj chaw muaj kev lag luam ib puag ncig.

Cov dej thiab chav dej hauv lub tshuab hluav taws xob thermal yog kev sib koom ua ke thoob plaws ntau cov txheej txheem tsim khoom, ua rau kev saib xyuas dej zoo yog qhov tseem ceeb rau kev ua kom lub cev muaj kev nyab xeeb thiab txhim khu kev qha. Kev saib xyuas zoo pab txhawb kev ua haujlwm ruaj khov ntawm cov dej thiab chav dej, txhim kho kev siv hluav taws xob, thiab txo cov cuab yeej siv. Raws li cov cuab yeej tseem ceeb rau kev saib xyuas online, tus ntsuas dej zoo ua lub luag haujlwm tseem ceeb hauv kev nrhiav cov ntaub ntawv hauv lub sijhawm. Los ntawm kev tawm tswv yim raws sij hawm, nws ua rau cov neeg ua haujlwm kho cov txheej txheem kho dej kom sai, yog li tiv thaiv cov khoom siv puas tsuaj thiab kev nyab xeeb, thiab ua kom muaj kev ua haujlwm zoo thiab ruaj khov ntawm lub zog tsim hluav taws xob.
Kev soj ntsuam pH qib: Tus nqi pH ntawm boiler dej thiab chav condensate yuav tsum tau khaws cia nyob rau hauv qhov tsim nyog alkaline ntau yam (feem ntau ntawm 9 txog 11). Kev sib txawv ntawm qhov no - txawm tias acidic lossis alkaline dhau heev - tuaj yeem ua rau cov yeeb nkab hlau thiab boiler corrosion lossis nplai tsim, tshwj xeeb tshaj yog thaum muaj impurities. Tsis tas li ntawd, cov qib pH txawv txav tuaj yeem cuam tshuam rau chav purity, uas ua rau muaj kev cuam tshuam rau kev ua haujlwm thiab kev pabcuam lub neej ntawm cov khoom siv qis xws li chav turbines.

Kev soj ntsuam xyuas conductivity: Conductivity yog ib qho qhia txog dej purity los ntawm kev xav txog cov concentration ntawm yaj ntsev thiab ions. Nyob rau hauv thermal fais fab nroj tsuag, dej siv nyob rau hauv systems xws li boiler feedwater thiab condensate yuav tsum tau raws li nruj purity qauv. Cov qib siab ntawm impurities tuaj yeem ua rau scaling, corrosion, txo thermal efficiency, thiab tej zaum yuav muaj teeb meem loj xws li yeeb nkab tsis ua hauj lwm.

Saib xyuas cov pa oxygen: Kev saib xyuas tsis tu ncua ntawm cov pa oxygen yog qhov tseem ceeb rau kev tiv thaiv oxygen-induced corrosion. Cov pa oxygen yaj hauv dej tuaj yeem hnov ​​​​mob nrog cov khoom siv hlau, nrog rau cov kav dej thiab cov cua kub hauv qhov cub, ua rau cov khoom degradation, phab ntsa thinning, thiab to. Txhawm rau txo qhov kev pheej hmoo no, cov nroj tsuag hluav taws xob thermal feem ntau ntiav cov deaerators, thiab cov tshuaj yaj oxygen yaj tau siv los saib xyuas cov txheej txheem deaeration nyob rau lub sijhawm, xyuas kom meej tias cov pa oxygen yaj nyob hauv qhov kev txwv (piv txwv li, ≤ 7 μg / L hauv boiler feedwater).

Cov ntaub ntawv kawm no tsom mus rau qhov piv txwv rack renovation project ntawm ib qho chaw thermal fais fab hauv Shanghai. Yav dhau los, cov rack sampling tau nruab nrog cov twj paj nruag thiab cov ntsuas los ntawm ib hom khoom txawv teb chaws; Txawm li cas los xij, qhov kev ua tau zoo ntawm qhov chaw tsis txaus siab, thiab kev txhawb nqa tom qab muag tsis tau raws li qhov xav tau. Yog li ntawd, lub tuam txhab txiav txim siab los tshawb nrhiav lwm txoj hauv kev. Botu Instruments tau raug xaiv los ua lub npe hloov pauv thiab ua qhov kev ntsuam xyuas ntxaws ntawm qhov chaw. Thaum lub hauv paus system suav nrog cov khoom siv hluav taws xob txawv teb chaws, ntws los ntawm khob, thiab cov kab sib pauv ion, tag nrho cov uas tau tsim los, cov kev npaj kho kom haum tsis yog hloov cov twj paj nruag thiab cov electrodes xwb tab sis kuj txhim kho cov dej ntws-los ntawm khob thiab ion pauv kab.

Thaum xub thawj, qhov kev tsim qauv tau pom zoo hloov kho me me rau lub khob ntws-los ntawm lub khob yam tsis hloov cov qauv dej uas twb muaj lawm. Txawm li cas los xij, thaum lub sijhawm mus ntsib tom ntej, nws tau txiav txim siab tias qhov kev hloov kho no tuaj yeem cuam tshuam qhov ntsuas qhov tseeb. Tom qab kev sab laj nrog pab neeg ua haujlwm engineering, nws tau pom zoo kom siv tag nrho BOQU Instruments 'cov lus pom zoo rau kev kho kom haum xeeb kom tshem tawm txhua yam kev pheej hmoo hauv kev ua haujlwm yav tom ntej. Los ntawm kev sib koom tes ntawm BOQU Instruments thiab pab pawg ua haujlwm hauv chaw ua haujlwm, qhov kev daws teeb meem tau ua tiav tiav, ua rau BOQU hom los hloov cov cuab yeej siv yav dhau los.

Qhov project rectification no txawv los ntawm yav dhau los fais fab nroj tsuag tej yaam num vim peb koom tes nrog cov sampling ncej chaw tsim tshuaj paus thiab cov kev npaj ua ntej. Tsis muaj teeb meem tseem ceeb cuam tshuam txog kev ua haujlwm lossis qhov tseeb ntawm cov cuab yeej thaum hloov cov khoom siv txawv teb chaws. Thawj qhov kev sib tw nteg nyob rau hauv kev hloov kho electrode waterway system. Kev ua tiav yuav tsum muaj kev nkag siab zoo ntawm lub khob dej electrode thiab kev teeb tsa hauv dej, nrog rau kev sib koom tes nrog cov neeg ua haujlwm engineering, tshwj xeeb tshaj yog rau cov yeeb nkab vuam dej. Tsis tas li ntawd, peb muaj kev sib tw kom zoo dua hauv kev pab cuam tom qab muag, tau muab ntau qhov kev cob qhia rau cov neeg ua haujlwm hauv tsev hais txog kev ua haujlwm ntawm cov khoom siv thiab kev siv kom raug.
