Nyob rau tib lub sij hawm, kev ntsuas xws li roj tsawg-sulfur thiab optimized cov khoom xyaw yuav tsum tau siv ntau npaum li sai tau thaum lub sij hawm tsim khoom kom txo tau cov pa emissions.
⑵ Kev kho dej khib nyiab
Cov txheej txheem pyrometallurgical tsim cov dej khib nyiab ntau, uas muaj ntau yam ntawm cov hlau hnyav ions thiab cov kuab paug organic. Txhawm rau kom ntseeg tau tias cov dej khib nyiab ua tau raws li cov qauv kev tiv thaiv ib puag ncig, ntau txoj hauv kev xws li lub cev, tshuaj, thiab kev siv roj ntsha tuaj yeem siv rau kev kho mob. Piv txwv li, cov txheej txheem tshuaj tuaj yeem tshem tawm cov hlau hnyav ions thiab cov kuab paug organic los ntawm acid-base neutralization, redox thiab lwm yam kev cuam tshuam; Cov txheej txheem lom neeg tuaj yeem degrade organic pollutants los ntawm cov kab mob.
⑶ Kev siv cov khoom pov tseg
Cov khib nyiab pov tseg uas tsim thaum lub sij hawm cov txheej txheem pyrometallurgical yog cov khoom siv txuas ntxiv dua tshiab thiab tuaj yeem siv los tsim cov khoom siv hauv tsev, chiv, thiab lwm yam. Txhawm rau txhim kho kev siv cov khib nyiab pov tseg, ntau txoj hauv kev tuaj yeem siv rau kev kho mob, xws li kub-kub melting. , tshuaj hloov dua siab tshiab, thiab lwm yam. Piv txwv li, high-temperature melting muaj peev xwm rho tawm cov hlau los ntawm pov tseg slag thaum hloov mus rau hauv cov khoom muaj nqis dua.
3. Kev txuag hluav taws xob ntawm pyrometallurgy
⑴ Pov tseg thaum tshav kub kub rov qab
Ib tug loj npaum li cas ntawm cov khib nyiab cua sov yog generated thaum lub sij hawm lub pyrometallurgical txheej txheem, uas yuav siv tau los tsim chav, dej kub, thiab lwm yam kom txo tau lub zog noj. Txhawm rau txhim kho kev siv cov khoom siv hluav taws xob pov tseg, ntau txoj hauv kev tuaj yeem siv rau kev kho mob, xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob pov tseg, thiab lwm yam. Piv txwv li, cov khoom siv hluav taws xob tuaj yeem rov ua dua cov khoom siv hluav taws xob los ntawm cov pa hluav taws xob thaum txo cov kev siv hluav taws xob tshiab.
⑵ Kev rwb thaiv tsev zoo
Nws yog ib qho tsim nyog kom muaj qhov kub thiab txias ib puag ncig thaum lub sij hawm pyrometallurgical txheej txheem, yog li kev ntsuas rwb thaiv tsev yuav tsum tau ua kom txo tau cov cua sov. Piv txwv li, cov ntaub ntawv rwb thaiv tsev tshiab thiab cov khoom siv hluav taws xob zoo tshaj plaws tuaj yeem siv los txhim kho cov rwb thaiv tsev. Tsis tas li ntawd, kev poob cua sov tuaj yeem txo los ntawm kev tswj tsis tau xws li cua thiab siab.
⑶ Kev ua kom zoo ntawm cov qauv hluav taws xob
Cov qauv hluav taws xob hauv cov txheej txheem pyrometallurgical muaj qhov cuam tshuam tseem ceeb rau kev siv hluav taws xob. Txhawm rau txo qis kev siv hluav taws xob, ntau txoj hauv kev tuaj yeem siv rau kev ua, xws li siv cov txheej txheem kev siv hluav taws xob tsawg, kev ua kom zoo ntawm cov khoom xyaw, thiab lwm yam. Piv txwv li, kev siv cov txheej txheem siv hluav taws xob tsawg tuaj yeem txo lub zog noj thaum lub sij hawm tsim khoom; optimizing cov khoom xyaw tuaj yeem txo qhov kev siv cov khoom siv hluav taws xob siab-siv cov khoom siv raw, yog li txo qis kev siv hluav taws xob tag nrho.
4. Cov lus xaus
Pyrometallurgy yog ib txoj kev siv hlau ua kom zoo, tab sis nws muaj qee yam teeb meem ntawm kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob. Txhawm rau daws cov teeb meem no, ntau yam kev ntsuas tuaj yeem ua. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tsim kho tshiab ntawm kev siv thev naus laus zis, kuv ntseeg tias kev lag luam pyrometallurgical yuav dhau los ua ib puag ncig zoo thiab txuag hluav taws xob.
