Aluminium Dross: Ib puag ncig kev sib tw
Aluminium dross muaj cov hlau txhuas thiab cov khoom tsis yog xim hlau xws li oxides, ntsev, thiab impurities. Nws yog tsim thaum lub sij hawm melting thiab refining ntawm txhuas seem los yog txhuas-muaj cov ntaub ntawv, thiab nws cov pov tseg poses ob peb tej teeb meem. Kev pov tseg tsis raug ntawm cov dross tuaj yeem ua rau cov av thiab dej paug, nrog rau kev tso tawm cov pa phem thaum hlawv.
Keeb kwm, dross feem ntau raug xa mus rau qhov chaw pov tseg lossis pov tseg ntawm txoj hauv kev uas tsim kev puas tsuaj rau ib puag ncig. Txawm li cas los xij, kev paub txog cov teeb meem ib puag ncig thiab kev lag luam ntawm cov khoom siv rov ua dua tshiab tau ua rau muaj kev txhim kho tshiab rau kev ua cov khoom pov tseg no.
Qhov tseem ceeb ntawm Aluminium Recycling
Aluminium yog cov khoom siv rov ua dua tshiab, thiab kev rov ua dua tshiab ntawm aluminium dross tuaj yeem txo qis kev siv hluav taws xob thiab lub tsev cog khoom roj emissions cuam tshuam nrog thawj cov khoom txhuas. Nws tsuas yog siv ib feem ntawm lub zog los rov ua dua aluminium piv rau rho tawm los ntawm bauxite ore.
Tsis tas li ntawd, cov khoom siv rov ua dua tshiab tuaj yeem ua rau muaj txiaj ntsig zoo ntawm aluminium, uas tuaj yeem siv rau ntau yam lag luam, suav nrog tsheb, kev tsim kho, thiab aerospace. Qhov no tsis tsuas yog txuag cov peev txheej ntuj xwb tab sis kuj txo qhov kev thov rau lub zog-intensive thawj aluminium ntau lawm.
Cov txheej txheem rau kev ua Aluminium Dross
Ntau txoj hauv kev thiab thev naus laus zis tau tsim los ua cov khoom siv txhuas ua kom zoo.
1. Cov txheej txheem cua sov
◆ Dross Cooling and Crushing: Nyob rau hauv txoj kev no, kub dross yog thawj zaug txias thiab ces crushed rau hauv me me hais. Tom qab ntawd cov crushed dross tuaj yeem ua tiav siv lwm txoj hauv kev.
◆ Dross Rotary Rauv: Cov txheej txheem no yuav tsum ua kom sov lub dross nyob rau hauv lub cub tawg, qhov twg cov hlau melts thiab sib cais los ntawm cov uas tsis yog-metallic Cheebtsam. Cov hlau molten tuaj yeem muab pov rau hauv ingots, thaum cov khoom seem tuaj yeem kho ntxiv.
2. Cov txheej txheem siv tshuab
◆ Dross Pressing: Dross tuaj yeem nias kom rho tawm cov kua txhuas, tawm hauv qab cov khoom seem qhuav. Cov hlau muab rho tawm yog tom qab ntawd ua tiav rau hauv cov ntaub ntawv siv tau.
◆ Dross Milling: Nyob rau hauv txoj kev no, dross yog milled los cais cov khoom siv hlau thiab tsis yog xim hlau. Cov hlau tuaj yeem rov qab tau thiab rov siv dua, thaum cov khoom tsis yog xim hlau tuaj yeem muab pov tseg kom nyab xeeb.
3. Cov txheej txheem tshuaj
◆ Salt Fluxing: ntsev fluxing yog siv cov ntsev kom yaj cov oxides nyob rau hauv lub dross, tawm hauv qab ib tug purified aluminium hlau. Txoj kev no yog tshwj xeeb tshaj yog zoo rau high-oxide dross.
◆ Reactive Gas Treatment: Reactive gases zoo li chlorine los yog fluorine tuaj yeem siv los ua cov tshuaj tsis yog xim hlau hauv cov dross, tso cai rau cov txhuas kom zoo.
Environmental thiab Economic Benefits
● Txo qhov cuam tshuam rau ib puag ncig: Los ntawm kev rov ua dua tshiab ntawm aluminium dross, peb txo qhov kev cuam tshuam ib puag ncig ntawm nws cov khoom pov tseg, suav nrog av thiab dej paug thiab huab cua.
● Kev txuag cov peev txheej: Cov khoom siv rov ua dua tshiab khaws cov khoom siv txhuas muaj txiaj ntsig thiab txo qhov kev xav tau ntawm bauxite mining, uas muaj nws tus kheej cov nyom ib puag ncig.
● Kev txuag hluav taws xob: Recycling aluminium yuav tsum muaj zog tsawg dua piv rau thawj cov khoom tsim tawm, ua rau txo qis hauv tsev cog khoom.
● Kev Lag Luam Tus Nqi: Rov qab aluminium los ntawm dross tsim ib qho tseem ceeb thib ob cov peev txheej uas tuaj yeem muag thiab rov siv dua, muab txiaj ntsig kev lag luam rau cov khoom siv rov ua dua tshiab.
● Kev Ua Raws Li Kev Cai: Kev ua kom raug tshem tawm kom zoo pab cov tuam txhab ua raws li cov kev cai ib puag ncig thiab txhim kho lawv lub luag haujlwm hauv zej zog.
Kev ua tiav ntawm aluminium dross tau los ntev los ntawm kev txhawj xeeb ib puag ncig kom dhau los ua kev coj noj coj ua thiab kev lag luam. Ntau txoj hauv kev thiab thev naus laus zis muaj niaj hnub no tsis yog tsuas yog pab txo qis kev cuam tshuam ib puag ncig ntawm kev puas tsuaj, tab sis kuj tseem pab txhawb kev txuag nyiaj thiab txuag hluav taws xob.
Raws li lub ntiaj teb tsom mus rau kev ruaj ntseg txuas ntxiv mus, kev lag luam txhuas tau nce zuj zus los siv cov txheej txheem siab heev rau kev ua tiav. Qhov kev hloov pauv mus rau lub luag haujlwm thiab kev tswj xyuas kom zoo tsis yog tsuas yog muaj txiaj ntsig zoo rau ib puag ncig tab sis kuj tseem muaj txiaj ntsig rau kev lag luam kev lag luam mus ntev. Los ntawm kev lees txais cov txheej txheem tshiab no, peb tuaj yeem ua kom muaj kev huv huv, ntsuab dua, thiab muaj kev nyab xeeb rau yav tom ntej rau kev lag luam txhuas.
