Ufa wa Coke ndi chinthu china chomwe chimapangidwa mu njira yophikira. Popeza tinthu take ndi tating'ono kwambiri, tikamasonkhana mu ng'anjo yophukira, mpweya sudzakhala wosalala, zomwe zidzakhudza kuyenda bwino kwa zinthu zomwe zili mu ng'anjo yophukira, ndipo sizingakwaniritse zofunikira za coke yachitsulo. Popeza ufa wa coke uli ndi mphamvu zambiri za kaboni, umapanga malo obisika mkati, komanso mphamvu zina, ofufuza asayansi aku China achita kafukufuku wozama komanso wozama wa momwe angagwiritsire ntchito ufa wa coke m'zaka zaposachedwa. HCMilling (Guilin Hongcheng) ndi kampani yopangakoka yachitsulomphero yoperaApa ndi pomwe tikufotokozera za kugwiritsa ntchito mphero yopukusira yachitsulo ya coke:

1. Mpweya wopangidwa kuchokera ku ufa wopukusira wa coke: Mpweya wopangidwa ndi kaboni ndi chinthu chokhala ndi kaboni wokhala ndi ma microporous komanso mphamvu yokwanira yothira madzi. Umagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga makampani opanga mankhwala, kukonza chakudya, kuteteza asilikali ndi makampani oteteza chilengedwe. Kagwiridwe kake ka kaboni kogwirizana ndi malo ake enieni, kuchuluka kwa ma micropore, kufalikira kwa ma pore ndi kapangidwe ka mankhwala. Pakadali pano, zinthu zazikulu zopangira kaboni wopangidwa ndi mafakitale m'dziko langa ndi matabwa ndi malasha. M'zaka zaposachedwa, chifukwa cha kusowa kwa mphamvu komanso dzikolo likugogomezera kwambiri kuteteza chilengedwe, anthu nthawi zonse amafunafuna zinthu zina zopangira kaboni wopangidwa ndi mafakitale. Ufa wa coke ndi chinthu chochokera ku makampani opanga coke. Uli ndi mpweya wokhazikika wambiri, mpweya wochepa komanso phulusa, mphamvu zambiri, komanso kupezeka mosavuta kwa zinthu zopangira. Ndi chinthu chabwino kwambiri chokonzekera mpweya wopangidwa ndi kaboni. Pakadali pano, mpweya wopangidwa ndi kaboni umapangidwa makamaka pochiza ufa wa coke pogwiritsa ntchito mphamvu ndi mankhwala. Njira yogwiritsira ntchito kaboni imafuna kuti zinthu zopangira ziyenera kusinthidwa kukhala kaboni musanagwiritse ntchito, kenako nkuyikidwa pa 600 mpaka 1200°C. Choyambitsa chimaphatikizapo mpweya wowonjezera monga CO2 ndi nthunzi ya madzi, ndipo maatomu a kaboni omwe ali mu mpweya wowonjezera wa kaboni oxide amagwiritsidwa ntchito kudutsa. Kaboni woyambitsa wokhala ndi ma pores opangidwa bwino amapangidwa ndi ntchito zotsegula, kufutukula ndikupanga malo atsopano. Kuyambitsa kwa mankhwala kumatanthauza kusakaniza zinthu zopangira ndi zoyambitsa (chitsulo cha alkali ndi alkali metal hydroxides, mchere wosapangidwa ndi ma acid ena) mu gawo linalake, kuzimiza kwa nthawi inayake, kenako kumaliza masitepe a carbonization ndi activation mu sitepe imodzi.

2. Kuchiza madzi otayira pogwiritsa ntchito ufa wa coke wopangidwa ndi zitsulo: njira yothira madzi ndi njira yodziwika bwino yogwiritsira ntchito pochiza madzi otayira pogwiritsa ntchito coke. Chifukwa cha malo obisika amkati mwa coke powder komanso momwe imathira madzi bwino, ofufuza ena ku China achita kafukufuku wokhudza kuchiza madzi otayira pogwiritsa ntchito coke powder. Zhang Jinyong amagwiritsa ntchito coke powder yomwe imayendetsedwa ndi nthunzi kuti itenge madzi otayira pogwiritsa ntchito biochemical kuchokera ku coking plant. Pambuyo pothira, kufunika kwa okosijeni (COD) kwa madzi otayira kumachepa kuchoka pa 233mg/L kufika pa 50mg/L, zomwe zimafika pamlingo wapamwamba kwambiri padziko lonse. Liu Xian ndi anzake adagwiritsa ntchito coke powder pochiza madzi otayira pogwiritsa ntchito coke powder, ndipo adaphunzira momwe zinthu zilili zoyenera kuti coke powder itenge madzi otayira pogwiritsa ntchito njira zoyesera zokhazikika komanso zosinthika. Zotsatira za kafukufukuyu zikusonyeza kuti COD ya madzi otayira a biochemical pambuyo pa chithandizo chapamwamba cha ufa wa coke ikhoza kuchepetsedwa kufika pa 100mg/L, ndipo kuchuluka kwa chromaticity yochotsa madzi kumatha kufika pa 60%, zomwe zimakwaniritsa zofunikira za khalidwe la madzi a makampani opanga coke.

3. Kupanga ufa wopukusira wa coke wachitsulo ndi zowonjezera: njira ya ufa wa coke yokha ilibe zomatira, ndipo nthawi zambiri imagwiritsidwa ntchito powonjezera chomangira kuti chikanikizidwe ndi kupangidwa. Pali mitundu yambiri ya zowonjezera za ufa wa coke, ndipo mtundu wa coke wopangidwa si wofanana. Liu Baoshan adagwiritsa ntchito chophatikiza cha humate, starch waste residue, coal slime, caustic soda ndi bentonite ngati chomangira kuti aphunzire kuchuluka kwa zowonjezera, momwe ufa wa coke umagwirira ntchito, mawonekedwe ndi kukula kwa tinthu tating'onoting'ono ta mpira woumba, ndi kutentha kouma, ndipo mipira yokonzedwayo idayesedwa ndikuwotchedwa, ndipo zotsatira zake zidawonetsa kuti mipira ya ufa wa coke inali ndi mphamvu yabwino komanso kukhazikika kwa kutentha, ndipo ingagwiritsidwe ntchito kupanga mpweya wopangidwa. Zhang Liqi adagwiritsa ntchito ufa wa coke ndi zotsalira za phula zopangidwa ndi jenereta ya gasi kuti zisakanizidwe ndi mawonekedwe malinga ndi kuchuluka kwina, kenako zimasungunuka ndi kusungunuka kuti zipange coke kuti ipange gasification. Katundu wa coke wafika pamlingo wa gasification coke. Imapereka maziko ophunzirira opanga mafakitale.

4. Ufa wa coke wophwanyidwa ndi zitsulo kuti apange coke wopangidwa ndi zitsulo: ufa wa coke nthawi zambiri umagwiritsidwa ntchito ngati chochepetsera kukhuthala kwa coke. Kuwonjezera ufa wa coke woyenera mu njira yopangira coke kungathandize kuti coke ikhale yabwino. Chifukwa cha kusowa kwa zinthu zopangira malasha ku China, kuti awonjezere zinthu zopangira malasha ndikuchepetsa mtengo wosakaniza malasha, makampani ambiri opangira coke ayesa kugwiritsa ntchito ufa wa coke ngati gawo losakaniza malasha popangira coke kuti apititse patsogolo phindu la chuma cha ufa wa coke. Makampani ambiri ku China achita kafukufuku pa kukula kwa tinthu tating'onoting'ono ndi kuchuluka kwa ufa wa coke. Yang Mingping adachita mayeso opanga mafakitale potengera mayeso ang'onoang'ono a uvuni wa coke. Zotsatira zake zikuwonetsa kuti pansi pa mikhalidwe yachizolowezi yopangira coke, ndizotheka kuwonjezera 3% mpaka 5% ya ufa wa coke kuti m'malo mwa malasha osalimba popangira coke. Mlingo wa block unakwera, ndipo kuchuluka kwa malonda kunakwera ndi pafupifupi 3%. Kudzera mu kafukufuku, Wang Dali ndi anzake adapeza kuti coke ndi ufa wa coke sikukhudza kwambiri vitrinite ya malasha osakanikirana. Komabe, poyesa ndi microscopic, zidapezeka kuti tinthu ta ufa wa coke tomwe ndi tating'onoting'ono toposa 0.2mm tinkasiyana mu coke, ndipo zinali zovuta kuphatikiza ndi zinthu zina, ndipo mawonekedwe ake sanasinthe; pomwe ufa wa coke wochepera 0.2mm unkakulungidwa mosavuta ndi colloid, zomwe zinali zabwino popanga coke. Chiŵerengero chabwino kwambiri cha ufa wa coke ndi 1.0%-1.7%, kukula kwa tinthu tating'onoting'ono tomwe ndi 98%-100% pansi pa 3mm, 78%-80% pansi pa 1mm, ndi 40%-50% pansi pa 0.2mm.

Kugaya kopangidwa ndi zitsulo sikusiyana ndi kugaya kopangidwa ndi zitsulo. Monga wopanga makina ogaya kopangidwa ndi zitsulo, HCMilling (Guilin Hongcheng) imapangakoka yachitsulo Raymondmphero, koka yachitsulo zabwino kwambirimphero, koka yachitsulo woongokachozungulirampherondi zida zina. Imatha kupanga ufa wa coke wachitsulo wa 80-2500 mesh ndikupereka chithandizo chaukadaulo pakugwiritsa ntchito ufa wopukusira wa coke wachitsulo.

Ngati muli ndi zofunikira pa mphero yopukusira ya coke yachitsulo, chonde musazengereze kulumikizana nafe kuti mudziwe zambiri za zidazo ndi kutipatsa malangizo otsatirawa:

Dzina la zinthu zopangira

Kusalala kwa chinthu (maukonde/μm)
