Hauv kev lag luam niaj hnub ntau lawm, Boilers ua si lub luag haujlwm tsis tseem ceeb yog "lub siab tsis tu ncua thiab cua sov rau cov kab ntau lawm. Txawm li cas los xij, ib qho tsis tseem ceeb tsis tseem ceeb -DUAB OXYGEN HAUV DEJ-} Ua zoo li Lurking "Killer Health Hiller," Kev Nyab Xeeb Kev Nyab Xeeb thiab Lifespan li cas.Cov pa hauv cov dej pub misPuas yog thawj qhov ua rau muaj kev txhim kho hauv cov kav boiler kav thiab khoom siv. No corrosion tsis yogLuv lub cuab yeej siv lub neejthiabNce Cov Nqitab sis kuj tseemua rau kev nyab xeeb xwm txheejnyob rau hauv cov neeg mob hnyav. Yog li ntawd, kom zoo tshem oxygen los ntawm boiler pub dej yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev nyab xeeb, ruaj khov, thiab kev lag luam ntawm kev lag luam ntawm boiler systems.
► I. ib txwm thiab lub ntsiab lus deoxygenation txoj kev
Rau lub sijhawm ntev, cov hauj lwm muaj tsim ntau yam tsis paub zoo deoxyenation thev naus laus zis, uas tuaj yeem yog cov qauv siv hauv lub cev thiab tshuaj lom neeg.
► 1. Txoj Kev Siv Lub Cev: Cua Sov Thiab Hlav Txo
Lub cev deexygenation yog cov txheej txheem tseem ceeb tshaj plaws, nrog nws cov ntsiab lus tseem ceeb siv roj av txo qis li kub nce lossis siab poob.
Thermal Dealer:Nov yog ib txoj kev siv dav dav tshaj plaws. DhauCov Khoom Siv Cua Kub Tshwj Xeeb(Thermal deeaerators), boiler pub dej yog rhuab kom npau npau, ua rau yaj oxygen kom dim ntawm kev txo qis. Cov pa yog tom qab ntawd rho tawm nrog chav, ua tiav deoxygenation. Hom no yog ua tau zoo heev, tshem cov feem ntau ntawm cov pa oxygen, tab sis nws yuav tsum tau noj ntawm cov chav thiab lub zog.
Nqus plua plav deoxyenation:Cov qauv no cuam tshuam nrog cov cua sib xyaw saum dej saum npoo av hauv lub tshuab nqus tsevLub Tshuab Nqus Tsev Twjkom txo siab. Hauv qhov qis - pa taws ib puag ncig txo, ua rau nws yooj yim dua rau cov pa oxygen cais tawm ntawm cov dej thiab yuav muab rho tawm. Piv rau cov kev siv hluav taws xob thermal ua haujlwm, nws ua haujlwm ntawm qis dua kub, txuag hluav taws xob thermal.
► 2. Tshuaj lom neeg: Kev ntsuas kev ntsuas ntxiv nrog cov tshuaj ntxiv
Thaum cov txheej txheem ntawm lub cev tsis tuaj yeem txo cov pa oxygen rau cov khoom siv tsis tshua muaj zog, cov khoom siv tshuaj lom neeg qhov twg yog qhov kev daws teeb meem tseem ceeb ntxiv lossis lwm yam kev daws teeb meem. Nws txoj ntsiab cai cuam tshuamNtxiv cov neeg sawv cev rau cov dej uas muaj tshuaj lom nrog oxygen, noj cov pa.
Cov tshuaj lom neeg ib txwm muaj xws li sodium sulfite, ntawm lwm tus. Qhov zoo dua ntawm hom no yognws yooj yim thiab yooj yim ntawm kev ua haujlwmCov. Txawm li cas los xij, nws tseem muaj kev txwv. Piv txwv li, qee tus neeg sawv cev yuav nce cov ntsev cov ntsiab lus ntawm cov dej, cuam tshuam rau cov dej khov kho, lossis qee qhov kev ua haujlwm zoo thiab yuav tsum muaj cov haujlwm tshwj xeeb. Yog li ntawd, tshuaj lom neeg deoxyenation feem ntau yog siv ua ib qho "Polishing" rau kev sib sib zog nqus dewoxyenation, ua ke nrog deoxyenation lub cev.
► II. Tawm thiab siv tau niaj hnub no cov tshuab deoxygenation
Nrog Technological kev nce qib, ntau dua thiab ib puag ncig kev npau suav zoo thev naus laus zis tau tshwm sim, muab cov kev xaiv tshiab rau kev kho dej haus dej.
► 1. Membrane deoxyenation: Xaiv tshiab rau kev sib cais
Membrane deoxyenation yog qhov tawm cov thev naus laus zis uas siv cov hmoov tshiab tshwj xeeb polymer rau roj av {{}}}} kua sib cais. Nws cov tub ntxhais tivthaiv yog ib lub follrophobic hollow fiber ntau uas "tso kua rau dhau tab sis tsis dej." Thaum pub dej ntws tawm ntawm ib sab ntawm daim nyias nyias, thiab lwm sab tau ua kom nqus tsev, cov pa oxygen sib txawv yog tsim thoob plaws daim nyias nyias. Qhov no ua rau cov pa oxygen nyob hauv dej kom dhau los ntawm daim membrane cov microses thiab yuav tshem tawm.
Qhov zoo tshaj plaws ntawm cov thev naus laus zis yog nws lub peev xwmrau Ua haujlwm ntawm chav tsev kub tsis muaj cua sov, ua rau muaj kev siv hluav taws xob tsawgCov. Ib qho ntxiv, cov khoom siv muaj cov hneev me thiab yooj yim thaum pib thiab nres. Nws deoxygenation efficiency yog ntau heev, ua raws li qhov xav tau ntawm niaj hnub boiler systems nrog cov tawv kom ua tau zoo.
► 2. Iner gas sparging: lub tswvyim ntawm lub cev hloov lub cev
Inert gas sparging (xws li siv nitrogen) yog lwm lub cev deoxyenation txoj kev mus ze. Nws lub hauv paus ntsiab lus yog raws li txoj cai ntawm ib feem pressures, qhov siab {1}- Purity Nitrogen tau nkag rau hauv cov dej, ua ntau cov npuas me me. Qhov no txo cov feem ib nrab ntawm oxygen rau hauv dej, yuam kom yaj oxygen kom khiav tawm thiab raug rho tawm nrog cov nitrogen. Hom no tseemTiv thaiv cov cua sov thiab yuav tsum tau kho cov roj roj kom zoo thiab sib xyaw ua ke.
►i. Lub hauv paus ntawm cov dej huv: ua kom muaj kev ua kom txaus siab rau qhov ua tau zoo los ntawm qhov chaw
Nws tsim nyog hais txog qhov ntawd, tsis hais txog kev siv tshuab hluav taws xob siab heev, nws cov txiaj ntsig zoo rau cov hauv paus tseem ceeb ntawm kev ntseeg {}}high - purity raw dejCov. Yog tias cov dej pub muaj cov calcium ntau xws li calcium, magnesium, thiab silicon, txo cov cua sov hauv lub rhaub dej, tab sis kuj cuam tshuam nrog cov txheej txheem deoxyenation. Yog li ntawd,Kev mob tob tob ntawm cov dej pub misyog qhov tseem ceeb ua ntej depoxygenation.
Hauv daim teb no,Rau Cov Boilerion Rau Boiler Pub DejCov thev naus laus zis yog ua si ntxiv txoj haujlwm loj dua. Qhov kev thev naus laus zis ua ke hluav taws xob hluav taws xob cov hluav taws xob thiab ion txauv, siv hluav taws xob kom tsav tsheb sib tsiv ntawm cov dej, yog li ua tiav tob kom huv. Ib qho zoo - tsimEDI DEJ KHO MOBMuaj peev xwm xwm yeem thiab stables tsim high - zoo huv si cov dej ntshiab.
Qhov tsis zoo li ion pauv kev sib pauv thev naus laus zis, uas yuav tsum tau siv cov tshuaj lom neeg thiab alkalis, lub peev xwm kom ua tiav hluav taws xob kev tsim tawm yam tsis muaj tshuaj lom neeg lossis tshuaj lom neeg. Qhov no ua rau tag nrho cov txheej txheem dej ntau lawm ib puag ncig ib puag ncig, kev siv tshuab, thiab yig. Nyob rau hauv loj- teev cov ntawv thov, tshwj xeeb yog nyob rau hauv cov xwm txheej zoo li electrariosization rau hluav taws xob cog, qhov ruaj khov thiab txhim khu kev qha yog qhov tseem ceeb. Ib chav dej kho EDI tau txais txiaj ntsig zoo rau kev kho dej yog qhov tseem ceeb rau tag nrho cov dej kho. Yog li ntawd, ib qho kev ua tiav edi edi dej tuaj yeem muab cov dej zoo tshaj plaws rau kev hais txog kev deoxyenation tom qab, ua kom cov dej muaj tsawg kawg nkaus.

Hauv cov ntsiab lus, tshem tawm cov oxygen los ntawm boiler pub dej yog ib txoj haujlwm zoo. NtawmKev Siv Lub Cev Siv Lub Cev thiab Tshuaj Rau Niaj Hnub Rau Niaj Hnub, txhua txoj kev muaj feem cuam tshuam nrog cov xwm txheej thiab cov txiaj ntsig thiab qhov tsis zoo. Txawm li cas los xij, kev ua tiav ntawm txhua cov tswv yim deoxygenation zoo siab rau cov tshuab hluav taws xob tau npaj los ntawm kev siv hluav taws xob zoo rau cov dej pheeb suab. Hauv kev kho dej niaj hnub kev xav, electrodeion rau cov boiler pub dej yog lub luag haujlwm yog lub luag haujlwm rau kev ua kom lub cev ua kom zoo nkauj "ua kom zoo dua rau cov pa tawm. Ob txoj haujlwm ua haujlwm synergistically pab ua ke txoj kab muaj zog ntawm kev tiv thaiv vim kev tiv thaiv kev nyab xeeb ntawm boilers.
