Coke powder ndi chinthu chomwe chimapangidwa pophika.Chifukwa tinthu tating'onoting'ono tating'onoting'ono, tikamaunjikana mu ng'anjo yophulika, kutuluka kwa mpweya sikudzakhala kosalala, komwe kungakhudze kuthamanga kwazinthu zakuthupi mu ng'anjo yophulika, ndipo sikungakwaniritse zofunikira za coke yachitsulo.Chifukwa chakuti ufa wa coke uli ndi mphamvu ya carbon high content, kupanga voids mkati, ndi mphamvu zina, ofufuza a sayansi aku China achita kafukufuku wozama komanso wozama wa momwe angagwiritsire ntchito ufa wa coke m'zaka zaposachedwa.HCMilling(Guilin Hongcheng) ndi wopangacoke metallurgicalmphero.Zotsatirazi ndikuyambitsa kugwiritsa ntchito mphero yachitsulo ya coke:

1. Mpweya wopangidwa kuchokera ku metallurgical coke grinding powder: Mpweya wopangidwa ndi carbon ndi carbon material yomwe imapangidwa ndi microporous structure ndi mphamvu yamphamvu ya adsorption.Amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga makampani opanga mankhwala, kukonza chakudya, chitetezo chankhondo ndi chitetezo cha chilengedwe.Kuchita kwa kaboni wolumikizidwa kumakhudzana ndi malo ake enieni, voliyumu ya micropore, kagawidwe kake ka pore ndi kapangidwe kake.Pakali pano, zida zazikulu zopangira mafakitale opangira mpweya wokhazikika m'dziko langa ndi nkhuni ndi malasha.M'zaka zaposachedwa, chifukwa cha kusowa kwa mphamvu komanso kutsindika kwa dziko pachitetezo cha chilengedwe, anthu nthawi zonse akuyang'ana njira zina zopangira zopangira carbon activated.Ufa wa Coke ndi wopangidwa kuchokera kumakampani ophika.Lili ndi mpweya wambiri wosasunthika, wochepa kwambiri komanso phulusa, mphamvu zambiri, komanso kupezeka mosavuta kwa zipangizo.Ndi zinthu zabwino kwambiri pokonzekera activated carbon.Pakali pano, activated carbon imapangidwa makamaka pochiza ufa wa coke poyambitsa thupi ndi kuyambitsa mankhwala.Njira yoyatsira thupi imafuna kuti zidazo ziyenera kukhala ndi kaboni zisanayambike, kenako ndikuyatsidwa pa 600 mpaka 1200 ° C.The activator imaphatikizapo mpweya wotulutsa okosijeni monga CO2 ndi nthunzi wamadzi, ndipo maatomu a kaboni omwe ali mu oxidizing carbon oxide material wa gasi amagwiritsidwa ntchito kudutsa.Mpweya wokhazikika wokhala ndi pores wopangidwa bwino umapangidwa ndi ntchito zotsegula, kukulitsa ndi kupanga ma voids atsopano.Chemical kutsegula amatanthauza kusakaniza zopangira ndi activators (zitsulo zamchere ndi alkali zitsulo hydroxides, mchere mchere ndi zidulo) mu gawo lina, kumiza iwo kwa nthawi inayake, ndiyeno kumaliza carbonization ndi kutsegula masitepe sitepe imodzi.

2. Kuchiza kwamadzi onyansa a biochemical ndi metallurgical coke grinding powder: adsorption njira ndi njira yodziwika bwino yogwiritsira ntchito coking madzi onyansa.Chifukwa cha kupangika kwamkati kwa ufa wa coke ndi magwiridwe antchito abwino a adsorption, ofufuza ena ku China achita kafukufuku wokhudza chithandizo cha ufa wa coke wamadzi otayira.Zhang Jinyong amagwiritsa ntchito ufa wa coke woyendetsedwa ndi nthunzi kuti adsorbe madzi onyansa a biochemical kuchokera ku chomera chophika.Pambuyo pa adsorption, kufunikira kwa okosijeni wamankhwala (COD) m'madzi oyipa kumachepetsedwa kuchoka pa 233mg/L mpaka 50mg/L, kufikira muyezo wapadziko lonse wotuluka.Liu Xian et al.anagwiritsa ntchito ufa wa coke pochiza kutsekemera kwachiwiri kwa madzi otayira, ndipo adaphunzira njira yoyenera yogwiritsira ntchito coke powder adsorption ya coking madzi onyansa ndi kuyesa kosasunthika komanso kwamphamvu kosalekeza.Zotsatira zafukufuku zikuwonetsa kuti COD yamadzi onyansa a biochemical pambuyo pa chithandizo chapamwamba cha ufa wa coke akhoza kuchepetsedwa kukhala osachepera 100mg / L, ndipo mlingo wa kuchotsa chromaticity ukhoza kufika kupitirira 60%, zomwe zimakwaniritsa zofunikira zamadzi amakampani ophika.

3. Kupanga metallurgical coke akupera ufa ndi zina: ndondomeko coke ufa palokha alibe adhesiveness, ndipo kawirikawiri ntchito powonjezera binder kwa izo kukanikiza ndi kupanga.Pali mitundu yambiri ya zowonjezera ufa wa coke, ndipo ubwino wa coke wopangidwa ndi wosiyana.Liu Baoshan anagwiritsa ntchito compoiling wothandizira wa humate, wowuma zinyalala zotsalira, malasha matope, caustic koloko ndi bentonite monga binder kuphunzira kuchuluka kwa zina, akamaumba zinthu za coke ufa, mawonekedwe ndi tinthu kukula kwa akamaumba mpira, ndi kuyanika. kutentha, ndi Mipira yokonzedwayo inayesedwa ndi kuthamangitsidwa, ndipo zotsatira zake zinasonyeza kuti mipira ya ufa wa coke inali ndi mphamvu zabwino komanso kukhazikika kwa kutentha, ndipo ingagwiritsidwe ntchito kupanga mpweya wopangira.Zhang Liqi adagwiritsa ntchito ufa wa coke ndi zotsalira za phula zomwe zimapangidwa ndi jenereta ya gasi kusakaniza ndi kupanga molingana ndi gawo linalake, kenako amathiridwa okosijeni ndi kaboni kuti apange coke kuti ipangitse mpweya.Katundu wa coke wafika muyezo wa gasification coke.Zimapereka maziko ongoyerekeza opanga mafakitale.

4. Metallurgical coke akupera ufa kuti apange metallurgical coke: ufa wa coke nthawi zambiri umagwiritsidwa ntchito ngati wothandizira kupatulira pophika.Kuonjezera ufa woyenerera wa coke mu njira yophika kungapangitse ubwino wa coke.Chifukwa cha kuchepa kwa zinthu zopangira malasha ku China, pofuna kukulitsa chuma cha malasha ndikuchepetsa mtengo wa kusakaniza kwa malasha, mabizinesi ambiri opangira malasha ayesa kugwiritsa ntchito ufa wa coke ngati chigawo chophatikizira cha malasha pakuphika kuti apititse patsogolo phindu lazachuma la coke. ufa.Mabizinesi ambiri ku China achita kafukufuku pa kukula kwa tinthu ndi kuchuluka kwa ufa wa coke.Yang Mingping adayesa kuyesa kwa mafakitale pamaziko a mayeso ang'onoang'ono a uvuni wa coke.Zotsatira zikuwonetsa kuti pansi pamikhalidwe yokhazikika yokweza pamwamba, ndizotheka kuwonjezera 3% mpaka 5% ya ufa wa coke m'malo mwa malasha owonda kuti aphike.Digiri ya block idakula, ndipo chiwongola dzanja chawonjezeka ndi pafupifupi 3%.Kupyolera mu kafukufuku, Wang Dali et al.anapeza kuti kuphika ndi ufa wa coke alibe zotsatira zoonekeratu pakuwonetseratu kwakukulu kwa vitrinite ya malasha osakanikirana.Komabe, kupyolera mu kuyeza kwa microscopic, kunapezeka kuti tinthu tating'onoting'ono ta coke zazikulu kuposa 0.2mm zinali zodziimira pa coke, ndipo zinali zovuta kugwirizanitsa ndi zigawo zina, ndipo mawonekedwewo sanasinthe;pamene ufa wa coke wocheperapo 0.2mm unali wokutidwa mosavuta ndi colloid, zomwe zinali zabwino kupanga coke.Mulingo woyenera kwambiri wa ufa wa coke ndi 1.0% -1.7%, mulingo woyenera kwambiri wa tinthu tating'onoting'ono ndi 98% -100% zosakwana 3mm, 78% -80% zosakwana 1mm, ndi 40% -50% zosakwana 0.2mm.

Metallurgical coke akupera ndi osasiyanitsidwa ndi metallurgical coke akupera mphero.Monga wopanga metallurgical coke akupera mphero, HCMilling(Guilin Hongcheng) umabalacoke metallurgical Raymondmphero, coke metallurgical zabwino kwambirimphero, coke metallurgical ofukulawodzigudubuzampherondi zida zina.Iwo akhoza kupanga 80-2500 mauna zitsulo coke ufa ndi kupereka thandizo luso ntchito zitsulo coke akupera ufa.

Ngati muli ndi zofunika pa metallurgical coke akupera mphero, chonde omasuka kulankhula nafe kuti mudziwe zambiri za zida ndi kupereka mfundo zotsatirazi kwa ife:
