Boiler Energy Recovery Exchanger Rau Luam Ntawv Cog
1, Cov ntsiab lus mob ntawm cov nqi hluav taws xob kub hauv cov tshuab luam ntawv boilers ceev yuav tsum tau daws
Nyob rau hauv cov txheej txheem ntawm cov chaw luam ntawv, boilers ua peb txoj haujlwm tseem ceeb: muab siab - cua kub kub rau lub qhov cub ntawm cov khoom tseem ceeb xws li gravure printing machines thiab dry laminating machines, kom ceev ceev number case kom qhuav thiab luam ntawv zoo; Muab cov cua sov rau lub tshuab luam ntawv rhiav thiab cov khoom siv raw khoom, tshwj xeeb tshaj yog kom muaj kev ruaj khov ntawm qhov kub thiab txias thaum lub caij kub; Muab chav dej los yog dej kub rau cov txheej txheem pabcuam xws li kev tu cov cuab yeej thiab cov kua mem dilution.
Txawm li cas los xij, feem ntau cov chaw luam ntawv feem ntau raug kev txom nyem los ntawm cov nqi hluav taws xob tseem ceeb thaum siv boilers. Raws li kev tshawb fawb kev lag luam cov ntaub ntawv, cov khib nyiab cua sov los ntawm boiler flue roj muaj ntau tshaj li 40% ntawm tag nrho cov khib nyiab hluav taws xob emissions los ntawm cov chaw luam ntawv. Ib qho nruab nrab -loj luam ntawv cog tuaj yeem tsim txog li 2000 kilowatt teev ntawm boiler khib kub ib teev. Yog tias tsis rov qab los, lub zog poob txhua xyoo yuav loj heev. Nyob rau tib lub sijhawm, kev tso tawm ncaj qha ntawm cov pa hluav taws kub kub kuj tuaj yeem ua rau muaj kev phom sij zais cia: sulfur dioxide, nitrogen oxides, plua plav thiab lwm yam khoom hauv cov roj flue tuaj yeem ua rau cov khoom siv flue, thiab kev tso tawm ncaj qha tsis ua raws li ib puag ncig emission qauv; Cov chav ziab khaub ncaws ua rau lub siab tsis zoo vim yog siab - qhov kub thiab txias tso pa tawm, thiab huab cua ntau hauv chav tsev tau rov ua dua, ntxiv rau kev siv lub zog ntawm lub boiler thiab ua rau lub voj voog tsis zoo ntawm "cov khoom siv hluav taws xob siab".
2. Core Working Logic of Boiler Heat Recovery Heat Exchangers Lub luag haujlwm tseem ceeb ntawm lub rhaub dej kub rov qab cov khoom siv hluav taws xob yog kom "nrhais" thiab rov siv qis dua -qib cua sov los ntawm boiler flue roj los ntawm lub cev kub pauv cov ntsiab lus, ua tiav qhov kaw - voj voog lub zog. Nws cov txheej txheem ua haujlwm feem ntau muaj peb theem: Ua ntej, siab - cov pa roj cua kub nkag mus rau hauv lub cev hluav taws xob los ntawm lub tshuab hluav taws xob. Cov khoom sib pauv cua sov hauv cov khoom siv hluav taws xob (xws li cov kav dej kub, cov raj finned, phaj kub exchangers, thiab lwm yam) tuaj rau hauv tag nrho kev sib cuag nrog cov roj flue, sai sai absorbing tshav kub los ntawm nws. Qhov thib ob, qhov nruab nrab ntawm kev sib pauv cua sov (feem ntau yog dej, huab cua, lossis cov roj thermal) circulates hauv lub tshav kub exchanger, hloov cov cua kub absorbed mus rau qhov predetermined daim ntawv thov scenario. Thaum kawg, cov roj flue txias tau tso tawm los ntawm cov flue tom qab ua tau raws li cov qauv emissions, thaum lub rhuab nruab nrab muab lub cua sov kom qhuav, cua kub dej, los yog txheej txheem chav rau lub tshuab luam ntawv, ua kom tiav cov kev hloov dua siab tshiab thiab kev siv hluav taws xob.
Txhawm rau ua kom tau raws li qhov xav tau ntawm lub zog sib txawv ntawm cov nroj tsuag luam ntawv, cov khoom siv hluav taws xob tuaj yeem hloov pauv mus rau ntau hom kev hloov pauv cua sov: yog tias xav tau cov cua sov kom qhuav, cua sov tuaj yeem xa ncaj qha mus rau qhov cub kom qhuav, hloov ib feem ntawm cov khoom siv hluav taws xob; yog tias xav tau cua sov lossis txheej txheem dej, cov dej kub tuaj yeem tsim los ntawm cov cua sov dej txias thiab txuas nrog lub tshuab cua sov los yog cov khoom siv hluav taws xob. Hom kev hloov pauv hloov pauv hloov pauv no tso cai rau nws kom haum rau ntau hom kev siv zog ntawm cov nroj tsuag luam ntawv.
3, Daim ntawv thov tus nqi: Kev txhawb nqa kev tsim kho kom ruaj khov ntawm cov chaw luam ntawv nrog cov txiaj ntsig triple
(1) Kev txo nqi thiab kev txhim kho kev ua haujlwm: txo cov nqi hluav taws xob zoo
Tus nqi hluav taws xob yog ib qho ntawm cov nuj nqis tseem ceeb rau kev ua haujlwm ntawm cov chaw luam ntawv, thiab daim ntawv thov ntawm boiler tshav kub rov qab cov cua kub exchangers tuaj yeem txo cov roj noj ntawm boilers (xws li cov nkev, diesel, thee, thiab lwm yam). Raws li kev lag luam cov ntaub ntawv tshawb fawb, tom qab kev txhim kho cov khoom siv hluav taws xob, kev siv hluav taws xob tag nrho ntawm cov chaw luam ntawv tuaj yeem raug txo los ntawm 15% -25%, nrog rau cov roj boiler txo qis mus txog 20% -30%. Siv lub tshuab luam ntawv nruab nrab uas siv 1 lab cubic meters ntawm cov roj av ib xyoos ib zaug, nws tuaj yeem txuag tau ntau pua txhiab tus yuan hauv cov nqi roj txhua xyoo, thiab cov peev nyiaj them rov qab feem ntau tsuas yog 1-2 xyoo, nrog rau cov txiaj ntsig ntev ntev.
(2) Kev tiv thaiv ib puag ncig ntsuab: nyob rau hauv txoj kab nrog kev sib tw ntawm qis - carbon kev loj hlob
Daim ntawv thov ntawm boiler tshav kub rov qab kub exchangers tsis tsuas yog txo tag nrho cov nqi ntawm cov roj combustion thiab emissions ntawm cov pa phem xws li carbon dioxide, sulfur dioxide, thiab nitrogen oxides, tab sis kuj txo cov pa roj kub kub raws li ib puag ncig emission qauv thiab txo cov plua plav emissions. Nyob rau tib lub sijhawm, kev siv hluav taws xob siv hluav taws xob txo qis kev cia siab ntawm fossil fuels, uas yog raws li lub teb chaws "dual carbon" lub tswv yim thiab ntsuab thiab qis -carbon txoj kev loj hlob ntawm kev lag luam luam ntawv. Nws pab cov lag luam dhau ib puag ncig daim ntawv pov thawj thiab txhim kho lawv cov lag luam kev sib tw hauv kev lag luam.
(3) Optimize ntau lawm: txhim kho cov cuab yeej ua haujlwm ruaj khov
Kev tso tawm ncaj qha ntawm siab - kub flue roj tuaj yeem yooj yim ua rau flue corrosion thiab cov khoom siv nrawm nrawm, thaum lub zog txias ntawm cov khoom siv hluav taws xob tuaj yeem tiv thaiv lub boiler flue thiab cov pa tawm tom qab, ua rau lub neej ntawm cov khoom siv. Tsis tas li ntawd, qhov thib ob siv thermal zog txo qhov zaus ntawm boiler pib- nce thiab kaw, ua rau boiler ua hauj lwm ruaj khov, txo cov kev pheej hmoo ntawm cov cuab yeej tsis ua hauj lwm, kom ntseeg tau lub continuation ntawm lub tshuab luam ntawv cov txheej txheem ntau lawm, thiab indirectly txhim kho ntau lawm efficiency.
4, Cov ntsiab lus tseem ceeb ntawm kev xaiv thiab kev teeb tsa
Thaum xaiv boiler tshav kub rov qab kub exchangers, luam ntawv factories yuav tsum xav txog tej yam tseem ceeb xws li boiler muaj peev xwm, tso cua sov, thiab lub zog xav tau, thiab tsom rau peb yam tseem ceeb: thawj, tshav kub hloov efficiency. High efficiency tshav kub pauv Cheebtsam xws li cov yeeb nkab kub thiab finned tube yuav tsum tau ua qhov tseem ceeb los xyuas kom meej qhov kev siv ntawm tshav kub zog rov qab; Qhov thib ob yog corrosion kuj ntawm cov khoom. Cov pa luam yeeb los ntawm lub tshuab luam ntawv yuav muaj me me ntawm cov khoom siv corrosive, yog li corrosion- cov ntaub ntawv tiv taus xws li stainless hlau thiab carbon steel coated nrog txhuas thiab zinc yuav tsum tau xaiv kom ntev lub neej kev pab cuam ntawm cov khoom siv; Qhov thib peb yog adaptability, uas yuav tsum tau customizing lub tshav kub exchanger qauv raws li lub boiler tso ntim thiab lub zog noj scenario nplai, kom tsis txhob muaj peev xwm pov tseg los ntawm "tus nees loj rub lub tsheb me" los yog "tus nees me rub lub tsheb loj".
Thaum lub sij hawm lub installation txheej txheem, yuav tsum tau them nyiaj mloog mus rau lub seamless kev twb kev txuas ntawm lub tshav kub exchanger thiab lub boiler tso system los xyuas kom meej cov ndlwg ntawm flue roj; Lub tshav kub pauv nruab nrab cov kav dej yuav tsum tau insulated kom txo tau cov cua sov; Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tau khaws qhov chaw txij nkawm tom qab kev tu thiab tu txhua hnub.
5, Xaus
Hauv kev sib tw hnyav zuj zus hauv kev lag luam luam ntawv thiab kev txhim kho txuas ntxiv ntawm kev tiv thaiv ib puag ncig, boiler cua sov rov qab cov khoom siv hluav taws xob tsis yog "cov khoom siv xaiv", tab sis "cov khoom siv tseem ceeb" rau cov chaw luam ntawv kom ua tiav kev txuag hluav taws xob, txo nqi, thiab kev hloov pauv ntsuab. Los ntawm kev rov ua kom zoo thiab rov siv dua boiler khib nyiab, nws tau daws qhov mob cov ntsiab lus ntawm kev siv hluav taws xob siab hauv kev luam ntawv ib txwm siv, thaum tsim cov txiaj ntsig tseem ceeb ntawm kev lag luam thiab ib puag ncig rau kev lag luam. Nyob rau hauv lub neej yav tom ntej, nrog rau kev siv thev naus laus zis tas li, boiler heat recovery heat exchangers yuav txhim kho mus rau kev ua tau zoo dua, kev txawj ntse, thiab kev yoog raws rau cov xwm txheej tshwj xeeb, dhau los ua ib qho tseem ceeb txhawb zog rau siab - kev loj hlob zoo ntawm kev lag luam luam ntawv.
