Coke hmoov yog ib yam khoom los ntawm cov khoom tsim tawm hauv cov txheej txheem coking.Vim tias nws cov khoom me me dhau lawm, thaum nws khaws cia rau hauv qhov cub tawg, cov cua ntws yuav tsis du, uas yuav cuam tshuam rau kev khiav haujlwm ntawm cov khoom siv hauv lub qhov cub tawg, thiab tsis tuaj yeem ua tau raws li cov kev cai ntawm metallurgical coke.Vim tias cov hmoov coke muaj cov ntsiab lus ntawm cov pa roj carbon ntau, tsim cov voids sab hauv, thiab qee lub zog, Suav cov kws tshawb fawb tshawb fawb tau ua tiav kev tshawb fawb dav thiab tob txog kev siv coke hmoov hauv xyoo tas los no.HCMilling (Guilin Hongcheng) yog cov chaw tsim khoom ntawmmetallurgical cokesib tsoo zeb.Hauv qab no yog ib qho kev qhia txog kev siv metallurgical coke sib tsoo zeb:

1. Activated carbon los ntawm metallurgical coke sib tsoo hmoov: Activated carbon yog cov khoom siv carbon nrog tsim microporous qauv thiab muaj zog adsorption muaj peev xwm.Nws yog dav siv nyob rau hauv ntau yam kev lag luam xws li tshuaj lom neeg kev lag luam, kev ua zaub mov, kev tiv thaiv tub rog thiab kev lag luam tiv thaiv ib puag ncig.Kev ua haujlwm ntawm cov pa roj carbon activated muaj feem xyuam rau nws qhov chaw tshwj xeeb, micropore ntim, pore loj faib thiab tshuaj muaj pes tsawg leeg.Tam sim no, cov khoom siv tseem ceeb rau kev tsim cov pa roj carbon activated hauv kuv lub teb chaws yog ntoo thiab thee.Nyob rau hauv xyoo tas los no, vim qhov tsis txaus ntawm lub zog thiab lub teb chaws tseem ceeb ntawm kev tiv thaiv ib puag ncig, tib neeg pheej nrhiav lwm cov khoom siv raw rau kev npaj cov pa roj carbon activated.Coke hmoov yog ib yam khoom los ntawm kev lag luam coking.Nws muaj cov ntsiab lus siab ruaj khov, tsis tshua muaj suab nrov thiab cov hmoov tshauv, lub zog siab, thiab yooj yim muaj cov khoom siv raw.Nws yog ib qho khoom siv zoo heev rau kev npaj cov pa roj carbon activated.Tam sim no, cov pa roj carbon activated feem ntau yog tsim los ntawm kev kho cov hmoov coke los ntawm kev ua kom lub cev thiab ua kom muaj tshuaj lom neeg.Txoj kev ua kom lub cev xav kom cov khoom siv raw yuav tsum tau carbonized ua ntej ua haujlwm, thiab tom qab ntawd qhib rau ntawm 600 txog 1200 ° C.Cov activator muaj xws li oxidizing gases xws li CO2 thiab dej vapor, thiab cov pa roj carbon atoms nyob rau hauv oxidizing carbon oxide khoom ntawm cov roj yog siv los ntawm.Cov pa roj carbon activated nrog cov pores zoo tsim los ntawm kev ua haujlwm ntawm kev qhib, nthuav dav thiab tsim cov voids tshiab.Kev siv tshuaj lom neeg yog hais txog kev sib xyaw cov khoom siv raw nrog cov activators (alkali hlau thiab alkali hlau hydroxides, inorganic ntsev thiab qee cov kua qaub) nyob rau hauv ib qho kev faib ua feem, immersing lawv rau ib lub sij hawm ntawm lub sij hawm, thiab ces ua kom tiav cov carbonization thiab ua kom cov kauj ruam nyob rau hauv ib kauj ruam.

2. Biochemical wastewater kho los ntawm metallurgical coke sib tsoo hmoov: adsorption method yog ib txoj kev siv los kho coking khib nyiab.Vim yog tsim cov voids sab hauv ntawm coke hmoov thiab zoo adsorption kev ua tau zoo, qee cov kws tshawb fawb hauv Suav teb tau ua kev tshawb fawb txog kev kho coke hmoov ntawm coking dej khib nyiab.Zhang Jinyong siv coke hmoov qhib los ntawm chav rau adsorb biochemical wastewater los ntawm coking cog.Tom qab adsorption, cov tshuaj oxygen xav tau (COD) ntawm cov dej khib nyiab raug txo los ntawm 233mg / L mus rau 50mg / L, ncav cuag lub teb chaws thawj-chav tawm tus qauv.Liu Xian et al.siv cov hmoov coke rau kev kho ob sab adsorption ntawm coking wastewater, thiab kawm txog cov txheej txheem tsim nyog rau coke hmoov adsorption ntawm coking khib nyiab los ntawm kev sim zoo li qub thiab tsis tu ncua.Cov txiaj ntsig kev tshawb fawb pom tau tias COD ntawm cov dej khib nyiab biochemical tom qab kev kho coke hmoov siab tuaj yeem raug txo kom tsawg dua 100mg / L, thiab cov chromaticity tshem tawm tuaj yeem ncav cuag ntau dua 60%, uas ua tau raws li cov dej zoo ntawm cov lag luam coking.

3. Kev tsim cov coke metallurgical sib tsoo hmoov nrog additives: cov txheej txheem coke hmoov nws tus kheej tsis muaj adhesiveness, thiab nws yog feem ntau yog siv los ntawm kev ntxiv ib binder rau nws rau nias thiab sib sau.Muaj ntau ntau hom coke hmoov additives, thiab qhov zoo ntawm cov coke tsim tsis zoo ib yam.Liu Baoshan siv cov khoom sib xyaw ua ke ntawm cov hmoov txhuv nplej siab, cov hmoov txhuv nplej siab pov tseg, cov coal slime, caustic soda thiab bentonite ua cov binder los kawm txog cov khoom ntxiv, cov txheej txheem molding ntawm coke hmoov, cov duab thiab qhov loj ntawm lub pob molding, thiab ziab. qhov kub thiab txias, thiab cov khoom npaj tau raug sim thiab raug rho tawm haujlwm, thiab cov txiaj ntsig tau pom tias cov pob coke hmoov muaj lub zog zoo thiab thermal stability, thiab tuaj yeem siv los tsim cov roj hluavtaws.Zhang Liqi siv cov hmoov coke thiab cov tar residue uas tsim los ntawm lub tshuab hluav taws xob roj los sib tov thiab cov duab raws li ib qho kev faib ua feem, thiab tom qab ntawd oxidized thiab carbonized los ua cov coke rau gasification.Cov khoom ntawm coke tau mus txog tus qauv ntawm gasification coke.Nws muab lub hauv paus theoretical rau kev tsim khoom lag luam.

4. Metallurgical coke sib tsoo hmoov los tsim metallurgical coke: coke hmoov feem ntau yog siv los ua tus neeg sawv cev hauv cov txheej txheem coking.Ntxiv cov hmoov coke tsim nyog hauv cov txheej txheem coking tuaj yeem txhim kho qhov zoo ntawm coke.Vim tias qhov tsis txaus ntawm cov khoom siv coking thee hauv Suav teb, txhawm rau nthuav dav coking thee peev txheej thiab txo tus nqi ntawm cov thee sib xyaw, ntau lub tuam txhab coking tau sim siv cov hmoov coke ua cov roj sib xyaw rau coking txhawm rau txhim kho cov txiaj ntsig kev lag luam ntawm coke. hmoov.Ntau lub lag luam hauv Suav teb tau tshawb fawb txog qhov loj me thiab feem ntawm coke hmoov.Yang Mingping tau ua qhov kev sim ntau lawm ntawm lub hauv paus ntawm kev sim coke cub me me.Cov txiaj ntsig tau pom tias nyob rau hauv cov txheej txheem saum toj kawg nkaus ntawm cov txheej txheem coking, nws muaj peev xwm ntxiv 3% mus rau 5% ntawm cov hmoov coke los hloov cov roj ntshiv rau coking.Lub block degree tau nce, thiab cov nqi pauv tau nce li ntawm 3%.Los ntawm kev tshawb fawb, Wang Dali et al.pom tias coking nrog coke hmoov tsis muaj kev cuam tshuam rau qhov siab tshaj plaws ntawm cov vitrinite ntawm cov thee sib xyaw.Txawm li cas los xij, los ntawm kev ntsuas microscopic, nws tau pom tias cov hmoov coke hmoov loj dua 0.2 hli yog ywj siab hauv coke, thiab nws nyuaj rau kev sib xyaw nrog lwm cov khoom, thiab cov duab tsis hloov;thaum cov hmoov coke me dua 0.2 hli tau yooj yim qhwv los ntawm colloid, uas yog qhov zoo rau kev tsim coke.Qhov kev pom zoo ntawm cov hmoov coke yog 1.0% -1.7%, qhov pom qhov loj me yog 98% -100% tsawg dua 3 hli, 78% -80% tsawg dua 1 hli, thiab 40% -50% tsawg dua 0.2 hli.

Metallurgical coke sib tsoo yog sib cais los ntawm metallurgical coke sib tsoo zeb.Raws li cov chaw tsim khoom ntawm metallurgical coke sib tsoo zeb, HCMilling (Guilin Hongcheng) tsimmetallurgical coke Raymondzeb, metallurgical coke ultra-zoozeb, metallurgical coke ntsugcov menyuamzebthiab lwm yam khoom siv.Nws tuaj yeem tsim 80-2500 mesh metallurgical coke hmoov thiab muab kev txhawb nqa rau daim ntawv thov ntawm metallurgical coke sib tsoo hmoov.
