Upfu hweCoke chinhu chinogadzirwa panguva yekubikwa. Nekuti zvidimbu zvayo zvidiki, kana zvikaunganidzwa muchoto cheblast, kufamba kwemhepo hakuzove kwakanyatsonaka, izvo zvinokanganisa kufamba kwakajairika kwekoramu yezvinhu muchoto cheblast, uye hazvigone kusangana nezvinodiwa zvecoke yesimbi. Nekuti upfu hweCoke hune hunhu hwekabhoni yakawanda, hwakagadzira ma voids emukati, uye simba rakati, vaongorori vesainzi vekuChina vakaita tsvakiridzo yakakura uye yakadzama pamusoro pekuti ungashandisa sei upfu hweCoke mumakore achangopfuura. HCMilling (Guilin Hongcheng) ikambani inogadzirakoke yesimbichigayo chekukuyaZvinotevera ndizvo zvinotsanangurwa pakushandiswa kwesimbi yekugadzira coke:

1. Kabhoni inoshandiswa kubva muhupfu hwesimbi hwecoke grinding: Kabhoni inoshandiswa mukugadzirwa kwekabhoni ine magadzirirwo akasimba e microporous uye kugona kwayo kunyudza. Inoshandiswa zvakanyanya mumabasa akasiyana-siyana akadai seindasitiri yemakemikari, kugadzira chikafu, kuchengetedza mauto uye indasitiri yekuchengetedza nharaunda. Kushanda kwekabhoni inoshandiswa kunoenderana nenzvimbo yayo chaiyo, huwandu hwe micropore, kugoverwa kwehukuru hwe pore uye kuumbwa kwemakemikari. Parizvino, zvinhu zvikuru zvekugadzira kabhoni inoshandiswa muindasitiri munyika yangu huni nemarasha. Mumakore achangopfuura, nekuda kwekushomeka kwesimba uye kusimbiswa kwenyika pakuchengetedzwa kwenharaunda, vanhu vari kugara vachitsvaga zvimwe zvinhu zvekugadzira kabhoni inoshandiswa muindasitiri. Upfu hwecoke hunobva muindasitiri ye coking. Hune huwandu hwakagadzika hwekabhoni, huwandu hushoma hwe volativity uye dota, simba rakawanda, uye kuwanikwa nyore kwezvinhu zvekugadzira. Chinhu chakanaka chekugadzira kabhoni inoshandiswa muindasitiri. Parizvino, kabhoni inoshandiswa muindasitiri inonyanya kugadzirwa nekurapa upfu hwecoke ne physical activation uye chemical activation. Nzira ye physical activation inoda kuti zvinhu zvekugadzira zvinofanira kupiswa kabhoni zvisati zvaitwa, uye zvobva zvaitwa pa 600 kusvika 1200°C. Iyo activator inosanganisira magasi anooxidating akadai seCO2 uye utsi hwemvura, uye maatomu ekabhoni ari muchinhu chinooxidating carbon oxide chegasi anoshandiswa kupfuura nepakati. Kabhoni inooxidating ine maburi akagadzirwa zvakanaka inoumbwa nemabasa ekuvhura, kuwedzera uye kugadzira ma voids matsva. Kushanda kwemakemikari kunoreva kusanganisa zvinhu zvisina kugadzirwa ne activators (alkali metal uye alkali metal hydroxides, inorganic salts nemamwe ma acids) mune imwe nhanho, kuanyudza kwenguva yakati, uye wozopedzisa matanho e carbonization uye activation nedanho rimwe chete.

2. Kurapa mvura yakasviba nemakemikari uchishandisa upfu hwecoke grinding powder: nzira yekunyudza mvura inzira yakajairika inoshandiswa kurapa mvura yakasviba inonyudza. Nekuda kwekuva nemhepo mukati mehupfu hwecoke uye kushanda zvakanaka kwekunyudza mvura, vamwe vaongorori muChina vakaita tsvakiridzo pakurapa upfu hwecoke powder. Zhang Jinyong anoshandisa upfu hwecoke hunobatidzwa nemhepo kuti anyudze mvura yakasviba kubva mufiriji. Mushure mekunyudza, kudiwa kwemakemikari eoxygen (COD) yemvura yakasviba kunoderedzwa kubva pa233mg/L kusvika pa50mg/L, zvichisvika padanho renyika rekutanga rekuburitsa mvura. Liu Xian nevamwe vake vakashandisa upfu hwecoke pakurapa mvura yakasviba inonyudza mvura, uye vakadzidza mamiriro akakodzera ekushandisa upfu hwecoke powder mukuyedza kunoenderera mberi. Mhedzisiro yekutsvagisa inoratidza kuti COD yemvura yakasviba yebiochemical mushure mekurapwa kwehupfu hwecoke hwepamusoro inogona kuderedzwa kusvika pasi pe100mg/L, uye mwero wekubvisa chromaticity unogona kusvika kupfuura 60%, izvo zvinosangana nezvinodiwa zvemhando yemvura yemakambani ekubika.

3. Kugadzira upfu hwesimbi hwecoke hwakakuyiwa nesimbi: maitiro eupfu hwecoke pachahwo hauna kunamira, uye hunowanzo shandiswa nekuwedzera chinobatanidza pahuri kuti chisimbiswe uye chigadzirwe. Kune mhando dzakawanda dzezvinowedzera zvecoke powder, uye mhando yecoke inogadzirwa haina kufanana. Liu Baoshan akashandisa chinhu chinobatanidza humate, starch waste residue, coal slime, caustic soda uye bentonite sechinobatanidza kuti adzidze huwandu hwezvinowedzera, mamiriro ekuumba ecoke powder, chimiro nehukuru hwechikamu chebhora rekuumba, uye tembiricha yekuomesa, uye mabhora akagadzirwa akaedzwa uye akapiswa, uye mhedzisiro yakaratidza kuti mabhora ecoke powder aive nesimba rakanaka uye kugadzikana kwekupisa, uye aigona kushandiswa kugadzira gasi rekugadzira. Zhang Liqi akashandisa upfu hwecoke netar residue yakagadzirwa nejenareta yegesi kusanganisa nekugadzira zvinoenderana nehuwandu hwakati, uye wozooxidized uye carbonized kugadzira coke yegesi. Hunhu hwecoke hwasvika padanho regasification coke. Inopa hwaro hwedzidziso yekugadzira maindasitiri.

4. Upfu hwekugaya hweCoke hwesimbi hunogadzira coke yesimbi: Upfu hweCoke hunowanzo shandiswa sechinhu chinotetepa mukuita kweCoke. Kuwedzera upfu hweCoke hwakakodzera mukuita kweCoke kunogona kuvandudza mhando yeCoke. Nekuda kwekushomeka kuri kuwedzera kwezviwanikwa zveCoke muChina, kuitira kuwedzera zviwanikwa zveCoke uye kuderedza mutengo wekusanganisa marasha, mabhizinesi mazhinji eCoke akaedza kushandisa Coke powder sechikamu chekusanganisa marasha eCoke kuti vawedzere mabhenefiti ehupfumi eCoke powder. Makambani mazhinji muChina akaita tsvakiridzo pamusoro pehukuru hwezvimedu uye huwandu hweCoke powder. Yang Mingping akaita bvunzo yekugadzira maindasitiri zvichibva pabvunzo yeCoke Oven diki. Mhedzisiro yacho inoratidza kuti pasi pemamiriro eCoke Uploading, zvinokwanisika kuwedzera 3% kusvika 5% yeCoke powder kutsiva Coal Lean yeCoke. Dhigirii reBlock rakawedzera, uye mwero wekutengeserana wakawedzera ne3%. Kuburikidza netsvakiridzo, Wang Dali nevamwe vake vakaona kuti Coke powder haina mhedzisiro yakajeka pakuona kwakanyanya kweVitrinite yeCoke Coal. Zvisinei, kuburikidza nekuyera nemicroscope, zvakaonekwa kuti zvidimbu zve coke powder zvakakura kupfuura 0.2mm zvaive zvakazvimiririra mu coke, uye zvaive zvakaoma kubatanidzwa nezvimwe zvikamu, uye chimiro hachina kuchinja; nepo coke powder iri diki pane 0.2mm yaiputirwa nyore nyore ne colloid, izvo zvaive zvakanaka pakuumbwa kwe coke. Chikamu chakakodzera che coke powder i1.0%-1.7%, huwandu hwakanaka hwe particles i98%-100% pasi pe3mm, 78%-80% pasi pe1mm, uye 40%-50% pasi pe0.2mm.

Kugaya kwesimbi necoke hakuparadzaniswi nesimbi necoke. Semugadziri wesimbi necoke, HCMilling (Guilin Hongcheng) inogadzira michina yekugaya.koke yesimbi Raymondchigayo, koke yesimbi zvakanaka kwazvochigayo, koke yesimbi yakatwasukachinotendererachigayonezvimwe zvishandiso. Inogona kugadzira upfu hwecoke hwesimbi hunosvika 80-2500 uye inopa rutsigiro rwehunyanzvi pakushandisa upfu hwecoke hwesimbi.

Kana muine zvinodiwa zvekugadzira simbi yecoke grinding mill, ndapota musazeza kutibata kuti muwane rumwe ruzivo nezvemichina yacho uye kutipa ruzivo rwekutevera:

Zita rezvinhu zvisina kugadzirwa

Kukora kwechigadzirwa (mesh/μm)
