Lead-acid roj teeb recycling daws siv evaporation crystallization technology los desulfurize cov hmoov txhuas nyob rau hauv cov dej khib nyiab ntawm cov roj lead-acid roj teeb thiab rov qab cov khoom los ntawm cov khoom kom ua tiav lub hom phiaj ntawm kev rov ua dua tshiab.
Lead-acid roj teeb recycling cov ntsiab lus
● Qhov tseem ceeb ntawm cov kua desulfurization nyob rau hauv cov kua qaub lead-acid cov khoom siv rov qab:
Ib tug loj npaum li cas ntawm acidic hnyav hlau muaj dej khib nyiab yog generated thaum lub sij hawm tsim cov txheej txheem ntawm txhuas-acid roj teeb. Yog hais tias nws raug tso tawm arbitrarily tsis kho, nws yuav inevitably ua phem rau ib puag ncig thiab tib neeg. Lead thiab cadmium nyob rau hauv cov dej khib nyiab yog cov hlau hnyav thiab ib hom pa phem. Yog tias lawv tsis rov siv dua thiab kho, tsis yog tsuas yog thaj chaw loj ntawm thaj av yuav tsum tau muab tso rau hauv qhov chaw los yog pov tseg, tab sis cov hmoov txhuas yog cov tshuaj lom thiab sulfuric acid heev corrosive. Lawv yuav ua rau muaj kev puas tsuaj loj rau ib puag ncig thiab av, thiab tib lub sijhawm, ua rau muaj kev puas tsuaj loj. Yog li ntawd, nws yog ib qho tsim nyog yuav tau kho cov pa phem ntawm cov roj lead-acid pov tseg.
● Khib lav lead-acid roj teeb siv technologies
Ib lub tshuab uas siv cov hmoov txhuas rov ua dua tshiab los ntawm cov khib nyiab-acid roj teeb thiab paub txog kev siv ntau yam khoom. Cov roj teeb khib nyiab tau txiav txim siab thiab txheeb xyuas, thiab tom qab ntawd cov roj teeb ntawm txhua qhov khoom tau ua tiav kom ua tiav lub hom phiaj ntawm kev rov ua dua tshiab.
Cov txheej txheem khiav ntawm pov tseg cov hmoov lead-acid roj teeb kho:
Cov txheej txheem ntws yog crushing thiab sorting ntawm cov hmoov lead-acid roj teeb, txhuas paste desulfurization (desulfurization thiab by-product recovery technology; oxygen-enriched combustion technology, yas granulation technology, carbon txo smelting technology, refining thiab alloy configuration technology.
01
Tom qab cov hmoov txhuas yog desulfurized, PbSO4 nyob rau hauv cov hmoov txhuas yog hloov mus rau hauv PbCO3, uas tuaj yeem txo qhov kub thiab txias ntawm 300 degree, paub qhov kub ntawm cov hmoov txhuas qis qis, txo lub zog noj, thiab txo cov tiam ntawm hmoov txhuas. ;
02
Cov txheej txheem smelting cov hmoov txhuas tsis tsim los yog ua rau me me ntawm SO2 cov pa phem tawm mus rau hauv cov huab cua, txo lub nra ntawm tus Tsov tus tw roj desulfurization ntawm chav tsev smelting, thiab ntau ntsuab thiab ib puag ncig tus phooj ywg;
03
Nws tuaj yeem paub txog kev rov ua dua tshiab ntawm S cov ntsiab lus hauv cov hmoov txhuas, npaj cov khoom siv purity siab ntawm ammonium sulfate lossis sodium sulfate, thiab tsim
Khib nyiab lead-acid roj teeb recycling evaporator txheej txheem ntws
ENCO's ammonium thiab sodium desulfurization txheej txheem rau cov hmoov txhuas muab tshuaj txhuam cov roj teeb uas siv lead-acid:
ENCO ntseeg hais tias cov khib nyiab lead-acid roj teeb rov ua dua yuav tsum siv ammonium los yog sodium txoj kev los desulfurize lead paste raws li cov khoom siv khib nyiab-acid roj teeb pov tseg, dej ntim thiab dej khib nyiab, thiab sim cais thiab rov qab tau cov peev txheej tseem ceeb ntawm cov khoom siv hluav taws xob. dej khib nyiab thaum kho cov dej khib nyiab.
Desulfurization hloov dua siab tshiab system rau cov hmoov txhuas paste ntawm cov roj lead-acid pov tseg:
Hauv cov khoom pov tseg cov hmoov lead-acid roj teeb cov ntaub ntawv rov qab, cov hmoov lead paste pre-desulfurization yog hais txog kev hloov pauv ntawm cov hmoov lead sulfate rau hauv cov hmoov lead carbonate los ntawm kev siv tshuaj. Desulfurizers tuaj yeem yog cov carbonate soluble (sodium carbonate, ammonium carbonate, NH bicarbonate, thiab lwm yam) thiab cov tshuaj alkaline (sodium hydroxide, NH dej, thiab lwm yam). Xav txog kev lag luam thiab kev ua haujlwm, sodium carbonate thiab ammonium bicarbonate yog qhov tsim nyog dua. Piv nrog rau cov txheej txheem ib txwm muaj, cov txheej txheem desulfurization tuaj yeem txo qhov kev siv cov hlau filings thiab cov kuab tshuaj, thiab tuaj yeem txo qhov kub kom txuag tau lub zog.
Desulfurization byproduct rov qab system rau cov hmoov txhuas muab tshuaj txhuam ntawm cov roj lead-acid pov tseg:
Cov kua desulfurization thiab cov khoom pov tseg cov kua qaub electrolyte tau muab tso rau hauv cov khoom siv rov qab los, thiab cov khoom siv sodium sulfate yog tsim tom qab neutralization, evaporation thiab crystallization technology kho.
Cov txheej txheem ntws ntawm cov desulfurization byproduct rov qab system rau cov hmoov txhuas muab tshuaj txhuam cov roj lead-acid pov tseg:
Tag nrho cov dilute sulfuric acid ntawm cov khib nyiab electrolyte yog sau thiab xa mus rau sulfate byproduct tiam system kom hloov mus rau hauv sodium sulfate khoom; cov kua disverted los ntawm crushing thiab sorting cov khoom thiab cov khib nyiab cov kua qaub los ntawm lwm qhov chaw yog tsim los ntawm acidic kua thiab electrolyte. Lawv tau sau rau hauv cov kua dej khib nyiab thiab tso rau hauv lub lim ua ke nrog cov desulfurization niam cawv kom tshem tawm cov khoom siv, thiab tom qab ntawd nkag mus rau cov khoom siv rov qab los. Tom qab neutralization, evaporation thiab crystallization technology kho, high-zoo sodium sulfate khoom yog generated. Cov khoom no tuaj yeem siv los ua cov khoom siv ntxiv rau cov tshuaj detergents, papermaking thiab iav khoom.
Cov txiaj ntsig zoo ntawm ammonium sodium desulfurization ntawm cov hmoov lead paste ntawm cov roj teeb lead-acid pov tseg:
Lub tuam txhab tau ua qhov kev sib tw kom zoo dua los txheeb xyuas nws qhov zoo thiab qhov tsis muaj zog piv rau nws cov neeg sib tw.
Cov ntsiab lus sulfur ntawm cov khoom yog ruaj khov thiab cov tshuaj tiv thaiv efficiency siab; cov khoom tsuas muaj cov ntsiab lus sulfur ntawm 0.6%.
01
Expansion suppression system: ntau lawm muaj peev xwm nce 4 zaug; purification system: hnyav hlau impurity cov ntsiab lus tsawg dua 5 ppm;
02
Txhua cov hmoov txhuas rov qab tuaj yeem txuag tau 1.36 tons ntawm cov qauv thee, txo cov khoom pov tseg los ntawm 98.7 tons, thiab txo cov sulfur dioxide los ntawm 0.66 tons;
03
Qhov thib ob siv desulfurization niam cawv ua rau txo qis zog;
04
Cov peev txheej rov qab tau zoo, cov khoom siv tsawg tsawg, thiab kev lag luam zoo rau cov khoom lag luam.
