Hebei roj cov chaw lag luam nrog ntau tshaj 100,000 tons ntawm cov roj boilers yuav tsum muaj qis-nitrogen txhim kho
Tsis ntev los no, Hebei tau tshaj tawm tsab ntawv ceeb toom ntawm NOx kev kho hauv cov roj ua dej.
Peb yog ib lub lag luam loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv nyuaj, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Cov Nroog (xws li Dingzhou, Xinji City) Cov Neeg Tsoom Fwv, Pawg Neeg Tswj Xyuas Koog Chaw Tshiab:
Yuav kom tob ntxiv txog kev tswj cov pa taws, txo nitrogen oxide emissions, txhim kho qhov zoo ntawm qhov chaw atmospheric, thiab yeej xiav ntuj tiv thaiv kev ua tsov ua rog, qhov chaw ua hauj lwm tam sim no nyob rau hauv NOx kho cov roj boilers yog raws li nram no:
Ua ntej, muab qhov tseem ceeb tshaj plaws rau, paub qhov teeb meem, thiab ua txoj haujlwm zoo hauv kev tswjhwm
Kev kho cov nitrogen oxides nyob rau hauv cov roj tua hluav taws yog ib qho tseem ceeb tshaj plaws los mus sib ntaus sib tua tiv thaiv tawm tsam huab xiav thiab ntxiv txhim kho qhov zoo ntawm qhov chaw atmospheric. Nws yog ib qho tseem ceeb tshaj plaws rau kev ua kom tob tob kom tswj tau huab cua phem thiab yog qhov tseem ceeb ntawm txoj kev tswj kev lag luam.
Muaj 10,771 cov khoom ntawm 36,563 tons ntawm cov roj boilers hauv lub xeev, ntawm 10,388 cov nplais ntawm cov roj tua hluav taws kub yog 10,388 tons ntawm cov pa roj boilers. Cov roj tua hluav taws kub yeej tsis kho nrog nitrogen oxides, thiab txhua xyoo cov pa roj nitrous oxides yog li ntawm 38,500 tons. Txog 150mg / m3.
Tsis tas li ntawd, qhov nruab nrab ntawm qhov nruab nrab ntawm nitrogen oxides nyob hauv peb lub xeev yog qhov siab, thiab qhov nruab nrab qhov nruab nrab ntawm nitrogen oxides ntau dua li ntawm cov hnyuv dioxide, uas yog ib qho ntawm cov txheej xwm tseem ceeb rau qhov tshwm sim ntawm cov tsho thiab siab ozone concentration.
Lub cheeb tsam puag ncig Beijing-Tianjin tau npaj rau kev kho mob nkev kom nkev thiab ua tiav cov txiaj ntsig. Beijing ua tiav qhov qis-nitrogen combustion reform ntawm cov roj boiler, thiab nitrogen oxide emission concentration hauv 30mg / m3, thiab tag nrho cov emission raug txo los ntawm 80%; Tianjin Lub zos tus qauv siv rau cov pa paug pa paug tawm, thiab nitrogen oxide emission concentration yog tswj li ntawm 80 mg / m3.
Txhua cheeb tsam yuav tsum ua kom lawv nkag siab, ntxiv dag zog rau lawv cov kev ua haujlwm nrog lub luag haujlwm ntawm lub luag haujlwm thiab kev ua siab loj los tuav lub luag haujlwm, kev cog lus ntawm lawv lub luag haujlwm, ua tus khiav haujlwm zoo thiab ua haujlwm tswj kev ua haujlwm, thiab ua haujlwm tshiab los yeej lub zog saum ntuj ceeb tsheej.
Qhov thib ob, qhia txog cov ntsiab lus tseem ceeb, kom paub cov hom phiaj thiab kev paub tab, thiab muab txoj kev sib ntaus tawm tsam kev tswj kav
Txhua cheeb tsam yuav tsum txhawb lawv txoj kev paub txog lub sij hawm txwv, npaj cov kev tsim nyog, thiab xyuas kom lawv cov hauj lwm tswj kom tiav raws sij hawm. Txog rau thaum xaus lub Rau Hli xyoo 2020, cov uas tsis muaj hluav taws xob uas tau siv hluav taws xob, cov dej kub npau npau, cov chaw taws ua kom sov thiab cov nplaum hluav taws kub muaj tag nrho ua tiav hlo cov roj tsawg. Cov hlab dioxide thiab cov oxides nitrogen muaj 5mg / m3, 10mg / m3, 30mg / m3, thiab cov roj ua dej tshiab uas tau ua tiav nrog cov khoom siv hluav taws xob tsawg tsawg thiab mus txog qhov kev tso tawm.
20 thooj taum / teev thiab cov pa roj carbon dioxide yuav tsum tau nruab nrog cov chaw tsis zoo saib xyuas cov pa phem, thiab koom nrog cov chaw tiv thaiv ib puag ncig, thaum nruab ib qhov kev tswj xyuas cov khoom siv (DCS system). Cov pa roj nkev uas muaj lub zog ua kom muaj li 20 tuj / moos yuav tsum tau nruab nrog lub tshuab roj nitrogen oxide. Lub chaw tshuaj ntsuam xyuas yuav tsum muaj peev xwm muab cov ntaub ntawv soj ntsuam xyuas txog kev nyab xeeb rau ib xyoos.
Ua ntej thaum lub kaum hli xyoo 2018, txhua lub nroog yuav tsum ua kom tiav 383 qhov chaw ntawm cov hlab roj nitrogen tsawg tsawg tshaj li 10 tons, ua kom tiav ob feem peb ntawm tag nrho cov koog ntawm thaum lub kaum hli xyoo 2019, thiab ua tiav txoj hauj lwm ntawm kev hloov qis-nitrogen ua ntej qhov kawg ntawm Lub Rau Hli 2020. Thov xaiv cov ntsiab lus ntawm qhov kev tshawb nrhiav thiab sau "Hybrid Boiler Low Nitrogen Combustion Reconstruction Schedule Teem", thiab txiav txim siab txog lub sijhawm tiav txhua lub sijhawm. Daim ntawv yuav muab ntaus nrog lub cim seev thiab lub tshuab hluav taws xob yuav muab xa mus rau lub xeev ib puag ncig tiv thaiv ua ntej Lub Xya Hli 10. Hall (tus ID nkag mus dqjp8780@126.com download daim ntawv, lo lus zais: dqjp87803253).
Qhov thib peb, ntxiv dag zog rau kev tiv thaiv kev tiv thaiv, saib xyuas cov kev ntsuam xyuas kom ua tau zoo
(1) Ntxiv zog rau kev coj noj coj ua. Lub Chaw Ua Haujlwm Saib Xyuas Kev Noj Qab Haus Huv Lub Nroog yuav koom nrog NOx txoj kev kho cov pa roj carbon monoxide hauv kev tswj hwm huab cua, ua ib qho kev sib txuas lus txhua lub hlis, ua tus saib xyuas thiab soj ntsuam, sib sau ua ke, daws teeb meem, thiab ua kom tiav cov hom phiaj thiab cov haujlwm. Kev txaj muag, kev saib xyuas, thiab kev tswj xyuas lub luag haujlwm tseem ceeb rau qhov tsis txaus siab, tsis zoo siab, thiab kev loj hlob zoo. Kev ua haujlwm tsis tiav rau lub sij hawm thiab qhov nruab nrab qhov nruab nrab ntawm nitrogen oxides tshaj li tus qauv, lub xeev cov koom haum tiv thaiv kev ruaj ntseg yuav ncua kev tso cai ntawm qhov tshiab ntxiv cov dej nitrogen oxide tsim dua ib qho kev ntsuam xyuas tej ntaub ntawv ntxiv rau cov neeg lub neej. Txhua lub hauv paus yuav tsum muaj kev txhawb nqa kom muaj kev koom tes, tswj kev ua haujlwm rau lub luag num, lub luag haujlwm thiab cov neeg muaj lub luag haujlwm, thiab soj ntsuam xyuas kev lees paub.
(2) Txhim kho txoj cai txhawb ntxiv. Formulate "Boiler Pa Pollutant Emission Standards nyob rau hauv Hebei xeev" kom ceev cov pa paug tawm txwv. Cov nyiaj pab tsim nyog yuav muab rau kev pab nyiaj txiag rau kev tswj hwm huab cua ntawm huab cua rau cov kev tswj kav uas tau dhau qhov kev tshuaj xyuas thiab kev lees paub. Yooj yim rau EIA cov txheej txheem tso cai, thiab ua qhov kev tswj xyuas hauv online ntawm kev siv kho hluav taws xob tsawg-nitrogen uas yog siv rau "Cov Cai Txog Kev Nyab Xeeb ntawm Kev Soj Ntsuam Zog ntawm Kev Tsim Hauj Lwm" (2017) ".
(3) Ntxiv zog rau kev soj ntsuam kev ruaj ntseg. Txhua cheeb tsam yuav tsum ua raws li kev saib xyuas tshwj xeeb thiab kev cai lij choj xyuas raws li qhov yuav tsum tau ua rau kev kho mob ntawm cov pa phem. Lawv yuav tsum yuam kom cov chaw lag luam yuav tsum tau muab ncua tseg rau kev ua haujlwm tsis tiav, ntxiv dag zog rau kev tswj xyuas txhua hnub, thiab kom muaj kev puaj phais. Rau cov teeb meem xws li ntau tshaj tawm, phaj ntawv, kev tso cai tsis pub muaj kev tiv thaiv ntawm chaw tiv thaiv chaw, smuggling thiab smuggling, thiab lwm yam., Muab kho kom dhau lub sij hawm txwv thiab raug txim raws li txoj cai; yog tias muaj kev coj cwj pwm txhaum cai, cov neeg ua haujlwm yuav tsum raug tshawb fawb rau lub txim txhaum.
(4) Txhim kho txoj haujlwm zoo. Tag nrho cov nroog thiab cov cheeb tsam yuav tsum muaj peev xwm ua kom muaj kev txawj ntse, kev txhawb nqa qhov project, txais kev saib xyuas, thiab siv nyiaj siv kev saib xyuas thiab kev tswj cov khoom siv lag luam, thiab xaiv cov khoom lag luam nrog cov khoom siv tau zoo, cov txiaj ntsim zoo, thiab cov xwm txheej zoo. Ntxiv dag zog rau kev tswj hwm kev sib tw tsev, npaj cov kev saib xyuas thiab kev xeem ntawm cov qhab-nees, thiab ua kom tiav ntawm qhov kev ua haujlwm zoo.
