Nyob rau lub Rau Hli 26, qhov kev tshaj tawm ntawm ecology thiab lub chaw tshaj tawm qhov kev kawm ntawm kev tswj xyuas thiab kev soj ntsuam ntawm cov chaw tseem ceeb ntawm 2018-2019 xiav ntuj tiv thaiv tsov rog.Ua raws li tsab ntawv ceeb toom, 473 cov dej taws hlawv lag luam yuav tsum raug tshem tawm ntawm daim ntawv tshuaj ntsuam, thiab ob lub npoo npau npau npau taws, nyiaj rau 0.4% ntawm tag nrho, tau pom tias tsis zoo lawm.9 pob zeb raug rho tawm haujlwm yuav raug muab tshem tawm ntawm daim ntawv.
Nrog rau ntau qhov kev tiv thaiv ntawm kev tiv thaiv ib puag ncig, kev tshem tawm thiab rectification ntawm ib co thee-raug rho tawm haujlwm boilers muaj attracted ntau xim.Thaum ntau lub xeev thiab regions, biomass yog qhov zoo ntxiv thiab lwm roj rau thee.Nrog lub nruam advancement ntawm lub "ultra- tsis muaj pa roj carbon dioxide, cov paj ntoo uas muaj cov pa roj carbon dioxide, cov pa roj carbon dioxide yuav tsum tau ntsib cov qauv "emission ultra-low".
Biomass puas muaj peev xwm ua tau raws li "kev tso tawm ultra-low emission" cov qauv ntawm cov hluav taws kub? Cov teeb meem dab tsi yog?
Ua li cas denitrification no raws li tus txheej txheem?
"Thaum lub tuam txhab tau siv thawj zaug biomass boilers xyoo 2007, nws ua raws li lub teb chaws 2003 txoj cai." Cov ntsiab lus ntawm nitrogen oxides, sulfur dioxide thiab yuav tsum tsis pub tshaj 200mg / m3, 100mg / m3 thiab 50mg / m3 raws li cov qauv ntawm 2003 rau lub emission atmospheric kuab paug nyob hauv thermal fais fab nroj tsuag (gb13233-2003) .Ntawm mou, lub taub hau ntawm ib lub tuam txhab kev lag luam hauv jiangsu biomass, tau tshaj tawm hais tias nws tsis nyuaj kom tau raws li cov txheej txheem emission.
Tab sis pib hauv 2013, 19 lub xeev (autonomous thiab thaj chaw) ntawm 47 hauv av theem qis thiab hauv nroog tau teev nyob rau hauv qhov chaw tswj kav, thermal power, steel, petrochemical, cement, nonferrous hlau, tshuaj lom neeg kev lag luam thiab li ntawm 6 qhov kev lag luam loj loj thiab cov hluav taws kub ua haujlwm muaj peev xwm ua kom muaj kev tso tawm tshwj xeeb. Cov pa roj carbon dioxide, cov tshuaj lom neeg xoos hnoos thiab xoos yog 100mg / m3, 50mg / m3 thiab 20mg / m3. "Txawm li cas los, qhov no tseem nyob deb ntawm cov" tsis tshua muaj emissions "ntawm nitrogen oxides ntawm 50mg / m3, sulfur dioxide ntawm 35mg / m3 thiab haus luam yeeb ntawm 5mg / m3, nws yog ib qho nyuaj rau kev siv tshuaj tua kab mob biomass boiler. Nyob hauv qee lub xeev, xws li zhejiang thiab shandong, nws nyuab dua rau cov tuam txhab muag biomass kom cais tawm ntawm cov hluav taws xob "ultra-low emissions".
Han qhia rau reporters tias qhov nyuaj tshaj plaws ntawm tus txheej txheem yog kho cov nitrogen oxides.Professional pawg neeg ntawm kev sib raug zoo ntawm lub tuam txhab ntawm kev lag luam ntawm kev lag luam ntawm cov hluav taws xob tauj dua tshiab, tus lwm thawj Secretary General Wang Weiquan taw tes tias tam sim no, qhov denitration links two of the mainstream (SNCR) .Cov khoom siv tau ncaj qha oxidize thiab pressurize lub lye mus nqus nws, nyob rau hauv txoj kev xav txo nitrogen oxide emissions thiab txawm lub rooj sib tham "ultra-low emissions" cov qauv.
Tiam sis hauv kev xyaum, Han Mou tau hais tias: "nyob hauv biomass boiler flue gas muaj alkali hlau, hnyav hlau, thiab lwm yam., Siv cov xim tsis tshua xeeb zuj zus los txo qhov tsis haum, thiab ntsaws, nruj hauv qhov kub qhov rai, qhov kub thiab qhov hloov mus rau qhov kub ntxhov ua rau qhov tsis zoo, qhov tsis tuaj yeem ua tau raws li cov kev xav tau ntawm cov dej huv.
Ntxiv rau qhov tseem ceeb, Wang Weiquan tau hais tias kev siv khoom, "tam sim no lub teb chaws biomass roj cua sov cua sov yog tseem me me, thiab cov khoom lag luam tshiab tam sim no rau cov pob zeb loj hluav taws xob, qhov loj qhov txawv loj heev , tus nqi rau bionass Enterprise yog tus nyuab heev los dais ".
Nws yog ib qho nyuaj ua kom tau nyiaj rau cov txheej txheem kev sib tw?
Lub ntsej muag nrog kev txaj muag ntawm kev siv tshuab thiab khoom siv, lub teb chaws biomass roj cov lag luam muaj cov kev ntsuas los ntawm kev ceev ntawm kev tiv thaiv ib puag ncig.
Nws yog to taub tias yuav kom muaj kev tiv thaiv ib puag ncig ntawm tus nqi tshwj xeeb ntawm "tshwj xeeb", Han Mou peb ntawm nws cov zaub mov qhuav muaj peev xwm ntawm 75 tonnes / teev ntawm biomass boiler siv lub "ozone + plasma technology" los tswj tus denitration.
"Thaum tom qab ntshav tawm cov pa luam yeeb, nyob rau hauv cov hluav taws xob high-voltage pulsed electric field, los ntawm dej, cov me me ntawm cov pa luam yeeb muaj cov hluav taws xob muaj zog, muaj oxygen, nyob rau hauv chav tsev sov kom tau cov nyiaj tshuav kub siab thiab qis ntshav, uas tsim tawm coob tus muaj siab zog electron thiab muaj zog oxidation kev kawm ntawm hydroxyl radicals xws li siab zog particles.Tsis tsuas muaj cov roj taws tau raug kho thiab cov roj tso tawm muaj tau lim, tab sis lub siab zog nquag hais tau zoo heev enhanced nws cov oxidation kev ua tau zoo.Han hais Cov kws kho mob hais tias cov txheej txheem no ua rau muaj kev mob tshwm sim zoo rau lub cev ua rau oxidize nitric oxide, uas ua rau cov khoom xyaw yav tom ntej kom oxidize nitrogen oxides. "Cov tshuaj tsuag no lub plhaub tom qab siv cov tshuaj tua kab zom zaws, sij hawm. TSIS TXHOB hauv qhov roj nplaim tau hloov mus rau hauv cov khoom siv roj nitrogen oxides rau hauv lub nqus nqus. "
Txawm hais tias muaj cov kev tseem ceeb thiab kev sib sim, tus taw tes qhia tau tias "biomass boilers muaj tsawg nyob hauv automation thiab cov ntsiab lus ntawm cov kuab paug hauv lawv cov pa tso pa tawm fluctuates.Thaum lub rau hli ntuj tshiab emissions ua khoom ntau lawm, kev khiav hauj lwm cov nqi txog 700000 yuan ib hlis, qhov chaw qub yog qhov tsis muaj roj biomass cov tuam txhab, cov nqi hnyav tau nce mus txog nws cov kev txwv. "
Tsis tas li, Wang Weiquan qhia rau tus reporter, tam sim no, cov roj biomass roj ntawm cov khoom siv raw li ntawm 800-1000 yuan / ton, biomass fuels feem ntau yog ua los ntawm cov hluav taws kub tua thiab ua, thiab cov ntoo ua nws tus kheej yog hom khoom siv Yeej muaj peev xwm ua rau lub tsev lag luam tsis muaj nuj nqis, txawm yog qhov muaj txiaj ntsig los ntawm cov khoom kub thiab lub siab tshaj qhov nyiaj, "tiam sis" cov txheej txheem ultra-low emission yog tsim nyog rau cov nqi hluav taws xob, roj, biomass boiler, Kev thov ncaj qha 'ultra-low emissions yog nyuaj.Technology ua hauj lwm hauv kev tshawb xav, tab sis tsis tau economically.Wang weiquan tau txais. "Vim cov combustion yam ntxwv ntawm biomass roj nws tus kheej, nws lub peev xwm boiler tam sim no txog 70 tons ib teev twg tshaj.Rau me biomass boilers nrog ib lub peev xwm ntawm ib tonne ib teev, tus qauv "ultra-low emissions" yog qhov yooj yim me ntsis.
Tsis tas li ntawd, vim yog cov khoom tawg tawm ntawm cov pa tawm tom qab biomass combustion yuav zoo dua, tseem xav tau ntxiv rau hauv cov pa nkev hauv tsev uas siv cov khoom siv plua av tshem tawm, cov kev hloov txhua hnub, cov khoom siv txij nkawm tseem yuav nce cov nqi kev lag luam.
"Lub tshuab hluav taws xob tsis zoo tshaj plaws ntawm biomass roj boilers tsis yog ib qho teeb meem kev teeb meem, tab sis ib qho kev lag luam." Nyob rau hauv lub qhov muag ntawm ib tug biomass, lub taub hau ntawm lub tuam txhab nyob rau hauv sab qaum teb ntawm Tuam Tshoj, tab sis nws lub xeev tseem tsis tau nug biomass rau Lawv yuav tsum ua raws li qhov kev ntsuas thiab kev ntsuam xyuas kev kawm thiab cov txheej txheem kev tso dej tshuaj zis kom tsim nyog.
