Tawm tsam qhov keeb kwm ntawm lub ntiaj teb decarbonization, cov hlau thiab ferroalloy kev lag luam tab tom ua rau kev hloov pauv tsis tau pom dua. Yav dhau los, kev sib tw tseem ceeb ntawm lub tuam txhab metallurgical nteg nyob rau hauv nws cov nplai thiab ntim; niaj hnub no, muaj peev xwm ua kom lub zog txo qis thiab ib puag ncig tus phooj ywg thaum tswj cov zis tau dhau los ua cov dej ntws rau kev muaj sia nyob hauv kev ua lag luam yav tom ntej. Nyob rau hauv qhov kev hloov pauv no, "Green Metallurgy" tau hloov zuj zus tshaj li cov lus hais rau kev ua raws cai rau hauv lub cav tseem ceeb rau kev hloov kho thev naus laus zis thiab kev ua kom zoo dua tus nqi.
Lub Ntsiab Tseem Ceeb ntawm Kev Hloov Hluav Taws Xob Niaj Hnub: Rov txhais cov Green Identity ntawm Industrial Furnaces
Yuav kom nkag siab tob txog Green Metallurgy, ib qho yuav tsum ua ntej qhia meej txog lub luag haujlwm ntawm cov chaw tsim khoom siv niaj hnub no- xws li Electric Arc Rauv (EAF) thiab Submerged Arc Rauv (SAF)- nyob rau hauv txoj kev txo cov pa roj carbon monoxide. Hauv cov txheej txheem smelting ib txwm muaj, ntau lub zog thermal poob los ntawm cov pa roj carbon monoxide, uas sawv cev rau ob qho tib si pov tseg loj ntawm cov peev txheej thiab kev siv cov pa roj carbon ntau ntxiv. Lub ntsiab lus ntawm Green Metallurgy yog, qhov tseeb, tsim kom muaj kev kaw - voj zog tswj qhov system.
Cov txheej txheem no xav kom peb saib cov khoom siv hluav taws xob ua kom muaj zog "chaw nres tsheb rov qab." Tshaj li nws qhov tseem ceeb smelting muaj nuj nqi, lub cub tsim tsim yuav tsum integrate zoo heev recycling. Lub hom phiaj ntawm kev smelting ntsuab yog qhov tseeb: txhawm rau khaws lub zog thermal thiab cov plua plav uas yuav cuam tshuam rau hauv huab cua thiab hloov lawv rov qab mus rau hauv lub zog tsim khoom, yog li txo qis kev cia siab rau qhov tsis yog - lub zog tauj dua tshiab ntawm qhov chaw.
Qhov Kaw -Loop Txoj Kev mus rau Tus Nqi: Los ntawm Cov Hluav Taws Xob Hluav Taws Xob rov qab mus rau Ultra- Tsawg Emission Design
Kev txhais lub zeem muag ntsuab rau hauv kev tsim khoom tiag tiag yuav tsum muaj txoj hauv kev ua haujlwm nruj. Cov tuam txhab lag luam niaj hnub no tab tom tsim kev ua haujlwm siab -kev ua tau zoo, qis- carbon smelting kev daws teeb meem rau cov neeg siv khoom los ntawm peb tus ncej tseem ceeb:
Ua ntej tshaj plaws yog Kev Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob (WHR). Qhov no yog qhov ncaj qha thiab siv tau zoo tshaj plaws los txo kev siv hluav taws xob. Los ntawm kev txhim kho siab -cov khoom siv hluav taws xob ua kom muaj txiaj ntsig zoo hauv lub tshuab hluav taws xob, siab- lub zog thermal zoo los ntawm cov pa hluav taws xob tuaj yeem raug ntes thiab hloov mus rau hauv chav dej los yog dej kub kom tsav cov tshuab hluav taws xob lossis cov cuab yeej pabcuam. Cov kev daws teeb meem ntau dua suav nrog kev siv hluav taws xob hluav taws xob ncaj qha rau Scrap Preheating, kom ntseeg tau tias cov ntaub ntawv ncav cuag qhov kub thiab txias ua ntej nkag mus rau hauv qhov cub. Cov ntaub ntawv qhia tau hais tias cov cuab yeej no tuaj yeem txo cov kev siv hluav taws xob tshwj xeeb rau ib tuj ntawm cov khoom los ntawm 10% -15%, txo cov nqi hluav taws xob ncaj qha.
Qhov thib ob yog Lub Taub Hau Taub Hau Taub Hau thiab Fluid Dynamic Optimization. Sealing yog qhov yuav tsum tau ua ua ntej rau kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob. Ib qho kev tsim muaj nyob rau hauv tsis tsuas yog tiv thaiv kev khiav tawm ntawm siab - kub flue gases, tab sis kuj tuav ib tug ruaj khov huab cua nyob rau hauv lub cub tawg, txo cov radiant tshav kub. Coupled nrog siab -precision Computational Fluid Dynamics (CFD) simulations, manufacturers tuaj yeem txhim kho txoj hauv kev sau cov pa, kom ntseeg tau tias cov pa nkag mus rau hauv cov tshuab ua kom huv nrog lub zog siv tsawg.
Qhov thib peb yog High-Kev Ua Haujlwm Baghouse Lim thiab Kev Tswj Xyuas Kev Ua Haujlwm. Ultra- qis emission yog qhov pib rau Green Metallurgy. Los ntawm kev sib koom ua ke siab -kev ua tau zoo membrane lim hnab, lub kaw lus tuaj yeem ntes micron - qib ultrafine plua plav, kom ntseeg tau tias emission metrics tshaj cov txheej txheem thoob ntiaj teb nruj tshaj plaws. Cov txheej txheem purification no tsis yog tsuas yog ua raws li kev ua raws cai xwb tab sis kuj yog rau kev rov qab los ntawm cov khoom siv hlau los ntawm cov plua plav, ntxiv cov nqi coj mus muag los ntawm cov khoom pov tseg.
Ntev -Lub Sij Hawm Tus Nqi Zog: Vim li cas qis -Carbon Path Dictates yav tom ntej kev vam meej
Tau nkag siab txog kev siv cov txuj ci, kev txiav txim siab- cov neeg tsim khoom yuav tsum paub txog cov laj thawj hauv qab no. Vim li cas thiaj xaiv ib lub chaw tsim khoom nrog kev paub txog ib puag ncig technologies yog lub zeem muag kev nqis peev rau pem hauv ntej-xav B2B cov neeg yuav khoom?
Qhov laj thawj tseem ceeb tshaj plaws yog kev txo qis ntawm kev tswj hwm thiab kev pheej hmoo se ib puag ncig. Nrog rau kev maj mam tsim kev lag luam thoob ntiaj teb cov teeb meem kev lag luam, xws li EU's Carbon Ciam Teb Hloov Kho Mechanism (CBAM), qhov pib nkag rau siab - cov khoom carbon yuav nce siab. Kev nqis peev hauv cov cuab yeej siv nrog WHR thiab ultra- muaj peev xwm ua kom qis qis tso cai rau cov khoom lag luam "Green Passport," zam lawv los ntawm cov nqi se carbon siab hauv kev lag luam thoob ntiaj teb yav tom ntej thiab ua kom muaj txiaj ntsig zoo dua.
Tom ntej no yog qhov tseeb ntawm cov nqi hluav taws xob. Hauv kev ua lag luam uas muaj tus nqi hluav taws xob tsis hloov pauv, cov lag luam uas muaj kev siv hluav taws xob ntau dua muaj kev pheej hmoo siab dua. Lub zog tsim los ntawm cov khoom pov tseg thaum tshav kub kub rov ua haujlwm ua "moat," tiv thaiv lub tuam txhab tiv thaiv kev nce nqi hluav taws xob.
Thaum kawg, muaj tus nqi them rau cov nqi lag luam thiab kev lav phib xaub. Hauv qab ntawm cov saw hlau, muaj ntau ntxiv ntawm cov neeg tsim khoom siab (xws li New Energy Vehicle thiab aerospace sectors) tab tom tshawb xyuas cov pa roj carbon hneev taw ntawm lawv cov khoom siv raw khoom. Cov neeg muag khoom uas muaj peev xwm smelting ntsuab muaj peev xwm ua kom ruaj ntseg ntev - lub sij hawm nyiam los ntawm cov neeg siv khoom siab tshaj no, ua tiav qhov kev dhia los ntawm "qis-kawg foundry" mus rau "siab-kawg ntsuab muab saw hlau tus khub."
Xaus
Hauv cov ntsiab lus, Green Metallurgy yog txoj hauv kev los ntawm kev kaw lub zog rau kev lag luam yeej. Los ntawm kev siv cov txheej txheem WHR kom "nce cov nyiaj tau los thiab txo cov kev siv nyiaj" ntawm lub zog, ua ke nrog seamless ultra- qauv tsim qis, cov tuam txhab tuaj yeem ua tiav qhov txo qis hauv kev siv hluav taws xob ib tuj thiab tsim kom ntev - lub sij hawm kev sib tw tsis sib haum xeeb nyob rau hauv lub ntiaj teb no tide ntawm carbon neutrality. Rau kev lag luam smelting yav tom ntej, "ntsuab" tsis yog xim xwb; nws yog ib qho kev sib sau ua ke ntawm kev txawj ntse thiab kev nkag siab ntawm kev lag luam foresight. Xaiv cov tuam txhab tsim khoom uas muab tag nrho - lub neej voj voog qis - cov kev daws teeb meem carbon yog, hauv paus, xaiv lub neej yav tom ntej ntawm kev loj hlob.
