Txoj haujlwm ntawm kev hloov pauv ntsuab tseem nyuaj.Kev lag luam steel yuav tsum paub txog peb qhov teeb meem
Zhang Dawei tau hais tias thaum ua tiav, peb yuav tsum ua tib zoo paub txog peb qhov teeb meem uas peb ntsib.
Ua ntej, cov txiaj ntsig ntawm kev tswj hwm tseem tsis tau ruaj khov, thiab qhov xwm txheej ntawm huab cua muaj kuab paug tseem yog qhov hnyav.Txawm hais tias lub teb chaws PM2.5 concentration tau nqis mus rau 29 micrograms ib lub cubic meter hauv 2022, nws tseem yog ob mus rau plaub npaug ntawm qib tam sim no hauv cov teb chaws Europe thiab Asmeskas, thiab rau lub sijhawm ntawm WHO cov lus qhia tshiab tshaj plaws."Hauv peb lub tebchaws, ib feem peb ntawm cov nroog tseem tsis tau mus txog tus qauv, feem ntau yog tsom mus rau thaj chaw muaj neeg nyob hauv nruab nrab thiab sab hnub tuaj, thiab feem ntau lub nroog uas muaj zog hlau thiab hlau ntau lawm tseem tsis tau txog tus qauv.""Cov huab cua zoo tseem poob qis ntawm lub hom phiaj ntawm kev tsim lub Tuam Tshoj zoo nkauj thiab kev tsim kho tshiab ntawm kev sib haum xeeb ntawm tib neeg thiab xwm," Zhang tau hais.Cov huab cua zoo tuaj yeem rov qab tau yooj yim yog tias muaj qhov yuam kev me me. "
Qhov thib ob, cov teeb meem ntawm cov txheej txheem yog qhov tseem ceeb, thiab kev hloov pauv ntsuab ntawm cov hlau thiab hlau tseem ua haujlwm ntev thiab nyuaj.Zhang Dawei tau taw qhia tias tag nrho cov emissions ntawm sulfur dioxide, nitrogen oxide thiab cov teeb meem me me los ntawm kev lag luam steel tseem yog thawj ntawm cov kev lag luam, thiab cov pa roj carbon dioxide emissions (15 feem pua) kuj yog thawj ntawm cov tuam txhab tsis muaj zog.Yog tias kev thauj mus los ntxiv, emissions tseem ntau dua."Lub hauv paus ua rau yog qhov teeb meem ntawm kev lag luam nws tus kheej tsis tau txhim kho hauv paus."Nws tau teev tseg tias, yog tias tus txheej txheem txheej txheem tau ua tiav los ntawm cov txheej txheem ntev, cov khoom siv hluav taws xob hluav taws xob rau hluav taws xob tsuas yog kwv yees li 10% ntawm tag nrho cov khoom tsim tawm ntawm cov hlau tsis huv, uas yog qhov sib txawv loj nrog lub ntiaj teb qhov nruab nrab ntawm 28%, 68% hauv. Tebchaws Asmeskas, 40% hauv European Union thiab 24% hauv Nyij Pooj.Tus qauv ntawm tus nqi yog tsuas yog sinter nrog high emission, thiab qhov feem ntawm pellets nyob rau hauv lub cub tawg yog tsawg tshaj li 20%, uas yog ib tug loj sib txawv nrog rau cov teb chaws Europe thiab Amelikas.Lub zog qauv yog dominated ntawm thee.Thee tso nyiaj rau 92% ntawm lub zog yuav los ntawm kev lag luam hlau thiab hlau.Kev lag luam thee siv nyiaj rau 20% ntawm tag nrho cov thee noj ntawm lub teb chaws (xws li coking), qeb thib ib hauv kev lag luam uas tsis yog hluav taws xob.Thiab li ntawd.
Tsis tas li ntawd, kev lag luam muaj cov khoom tsis txaus ntawm cov thev naus laus zis tseem ceeb los txo cov pa phem thiab carbon."Nws yog qhov ceev nrooj los rhuav tshem cov txheej txheem thiab txoj cai txwv kev lag luam ntawm cov hlau thiab tshuaj lom neeg kev lag luam, txhawb lub zog ntawm kev tsim kho thev naus laus zis hauv kev lag luam, thiab ua kom yooj yim rau kev tshawb fawb thiab kev tsim vaj tsev ntawm kev cuam tshuam thiab kev tsim kho tshiab-carbon metallurgical technologies."Zhang Dawei tau taw qhia tias tam sim no "ob chav carbon" keeb kwm yav dhau los, kev lag luam steel ntsuab hloov pauv cov pa roj carbon tsawg yog qhov nyuaj.
Thib peb, kev nce qib hauv cov pa hluav taws xob tsawg yog nyob rau hauv txoj kab nrog kev cia siab, tab sis qee qhov teeb meem yuav tsum tsis txhob raug ignored.Ua ntej, kev nce qib hauv qee thaj tsam poob qis.Cov tuam txhab teev npe feem ntau yog tsom rau hauv cheeb tsam Beijing-Tianjin-Hebei thiab thaj chaw ib puag ncig thiab Fen-Wei Plain, thaum cheeb tsam Yangtze River Delta tau ua haujlwm qeeb.Tam sim no, tsuas yog 5 lub lag luam hauv thaj chaw tsis tseem ceeb tau ua tiav tag nrho cov txheej txheem hloov pauv thiab tshaj tawm nws.Feem ntau cov lag luam hauv qee lub xeev yog nyob rau theem pib ntawm kev hloov pauv.Qhov thib ob, qhov zoo ntawm qee lub lag luam tsis siab.Qee lub tuam txhab muaj qee qhov teeb meem, xws li kev xaiv cov txheej txheem tsis tsim nyog, kev hloov pauv tsis tiav, hais txog qhov kawg ntawm kev tswj hwm kev tiv thaiv thiab kev tswj hwm.Thib peb, qhov zoo ntawm kev soj ntsuam thiab saib xyuas kev ua haujlwm yuav tsum tau txhim kho."Qee lub lag luam tsis nyob rau hauv qhov chaw los hloov kho, txhawm rau kom dhau qhov kev tshaj tawm, ntawm kev ntsuam xyuas thiab kev saib xyuas ntawm 'qeeb siab', kev ua haujlwm tsis nruj thiab tsis muaj zog, thiab txawm tias kev dag ntxias."Zhang Dawei tau taw qhia tias txhawm rau txhawm rau txhim kho qhov zoo ntawm kev soj ntsuam thiab saib xyuas kev ua haujlwm, Ministry of Ecology thiab Ib puag ncig thiab Steel Association tau tuav ntau qhov kev sib tham hauv 2022, thawb lub koom haum los tsim cov qauv qhia thiab nruj me ntsis rau kev tshaj tawm, tab sis qhov teeb meem tseem muaj. muaj nyob rau qhov sib txawv. "“Nws tau taw qhia.Thib plaub, cov lag luam ib leeg tau so kev tswj hwm tom qab tshaj tawm, thiab txawm tias tus cwj pwm tsis raug cai.
Kev tiv thaiv qib siab ntawm ecological ib puag ncig, steel kev lag luam thiab kev lag luam ua plaub "ntau dua"
Zhang Dawei tau hais tias qhov kev txiav txim siab tag nrho ntawm Ministry of Ecology thiab Ib puag ncig xyoo no yog ua raws li "peb qhov kev tswj hwm kev ua qias tuaj" thiab "tsib qhov kev ntsuas", txiav txim siab tawm tsam "ib-loj-haum-tag nrho", tawm tsam qhov kev txiav txim. ntawm ntau txheej.Thaum ua tiav kev tswj hwm huab cua, lub chaw haujlwm yuav tswj xyuas kev ua haujlwm zoo ntawm kev lag luam thiab kev lav phib xaub, thiab txhawb txoj kev loj hlob zoo ntawm kev lag luam steel nrog kev tiv thaiv qib siab.
"Nws tau tawm tswv yim tias kev lag luam steel thiab cov lag luam yuav tsum cuam tshuam nrog 'peb kev sib raug zoo', uas yog, cuam tshuam nrog kev sib raug zoo ntawm palliative thiab cov hauv paus hauv paus, lub sij hawm ntev thiab luv luv, kev loj hlob thiab kev txo qis, thiab ua plaub' ntau saib '."Zhang Dawei qhia.
Ua ntej, peb yuav xyuam xim ntxiv rau cov qauv thiab qhov chaw emission txo kev ntsuas."Raws li lub hom phiaj ntawm lub hom phiaj 'ob-carbon' tam sim no, peb yuav tsum tau saib xyuas ntau dua rau cov qauv, qhov chaw thiab lwm yam kev ntsuas.Kev ua lag luam carbon yav tom ntej thiab cov nqi ntawm cov pa roj carbon monoxide kuj tseem yuav muaj kev cuam tshuam loj heev rau kev txhim kho kev lag luam, thiab peb yuav tsum saib mus ntev. "Zhang tau hais tias kev lag luam steel yuav tsum tsom mus rau kev nce qib ntawm cov txheej txheem luv luv steel hauv cov hluav taws xob hluav taws xob;Ua kom muaj kev faib ua feem ntawm cov pellets siv rau hauv qhov cub tawg thiab txo kev siv sinter;Peb yuav txhim kho kev siv hluav taws xob zoo, nce kev faib ua feem ntawm cov hluav taws xob ntsuab siv, thiab hloov lub zog huv hauv cov hluav taws xob hluav taws xob hluav taws xob.Central thiab lub xeev cov tuam txhab lag luam yuav tsum ua lub luag haujlwm tseem ceeb thiab ua tus thawj coj hauv kev ua qauv qhia thiab kev siv kev sib koom tes thev naus laus zis hauv kev txo cov pa phem thiab carbon.
Qhov thib ob, peb yuav them sai sai rau qhov zoo ntawm ultra-low emission transformation.Qhov project loj no yuav tsis tsuas yog yuam cov tuam txhab lag luam los sib koom ua ke thiab rov tsim kho, txhim kho cov cuab yeej siv, thiab txhim kho tag nrho cov ntsuab thiab cov pa roj carbon tsawg ntawm kev lag luam steel, tab sis kuj tseem siv zog kev lag luam zoo thiab pab txhim kho kev lag luam kev loj hlob."Peb tau hais ntau zaus rau ntau lub sijhawm uas qhov kev hloov pauv qis qis qis yuav tsum siv zog rau 'plaub qhov tseeb', kom ua tiav 'plaub yuav tsum thiab plaub tsis ua', thiab yuav tsum sawv qhov kev sim ntawm keeb kwm."Zhang Dawei hais tias.
Thib peb, peb yuav tau them nyiaj ntau dua rau kev ua tiav cov kev xav tau qis qis rau ntawm lub hauv paus ruaj khov thiab ruaj khov."Cov tuam txhab lag luam uas tau ua tiav qhov kev hloov pauv qis qis qis thiab kev tshaj tawm yuav tsum ntxiv dag zog rau cov haujlwm ntawm cov koom haum tswj hwm ib puag ncig, txhim kho cov txheej txheem kev tshaj lij ntawm cov neeg ua haujlwm tswj hwm ib puag ncig, thiab muab kev ua si tag nrho rau lub luag haujlwm txhawb nqa ntawm kev tswj xyuas kev thauj mus los, tsis muaj kev sib koom ua ke thiab huv. rau kev tswj ib puag ncig tsim nyob rau hauv cov txheej txheem ultra-low emission transformation, thiaj li ua tiav kev ruaj khov ultra-low emissions.Nws tsis yooj yim ua. "Zhang Dawei tau hais tias tam sim no ultra-low emissions ntawm steel tau tsim ib tug ntau-tog saib xyuas mechanism uas muaj xws li tsoom fwv, cov lag luam thiab cov pej xeem.
Nws tau hais tias nyob rau hauv cov kauj ruam tom ntej, Ministry of Ecology thiab ib puag ncig yuav coj tsoomfwv hauv nroog kom siv tag nrho cov cai sib txawv, nce txoj cai txhawb nqa rau cov lag luam qis qis qis qis, thiab hais kom Lub Koom Haum Steel tshem tawm cov ntawv ceeb toom pej xeem ntawm cov lag luam uas. tsis tuaj yeem ua tiav ultra-low emission thiab muaj tus cwj pwm tsis raug cai.Ntawm qhov tod tes, peb yuav ntxiv dag zog rau kev soj ntsuam kev cai lij choj thiab kev saib xyuas nruj ntawm cov tuam txhab uas tsis tau ua tiav qhov kev hloov pauv ntawm cov pa hluav taws xob tsawg.
Plaub, ua tib zoo saib xyuas kom txo cov pa phem thiab cov pa roj carbon ntau hauv kev thauj mus los.Kev lag luam hlau thiab hlau yog qhov kev lag luam tseem ceeb hauv kev sib ntaus sib tua ntawm cov tsheb thauj khoom, thiab cov emissions los ntawm kev thauj mus los yog kwv yees li 20% ntawm tag nrho cov emissions ntawm tag nrho cov nroj tsuag."Tom ntej no, cov tuam txhab lag luam yuav tsum tau them nyiaj ntau dua rau kev ua kom zoo ntawm kev thauj mus los sab hauv thiab sab nraud ntawm cov nroj tsuag, txhim kho qhov kev faib ua feem ntawm kev thauj mus los huv ntawm cov ntaub ntawv thiab cov khoom lag luam sab nraum cov nroj tsuag, kev thauj mus los hauv nruab nrab thiab ntev los ntawm kev tsheb ciav hlau lossis dej, kev thauj mus los hauv nruab nrab thiab luv luv los ntawm yeeb nkab gallery los yog lub zog tshiab tsheb;Kev tsim kho txoj siv sia, taug kev thiab cov menyuam lub rooj tsheb thauj mus los yuav raug coj los siv hauv lub Hoobkas kom txo qis cov tsheb thauj mus los hauv lub Hoobkas thiab tshem tawm qhov hloov pauv thib ob ntawm cov khoom hauv lub hoobkas. "Zhang Dawei tau hais tias, tau tshaj tawm, rau rau lub tsheb thauj mus los ntawm kev lag luam, kuj tau hais tias peb ntxiv kev txhim kho cov qauv kev thauj mus los, txhim kho qhov feem ntawm kev thauj mus los huv.
