Impuphu ye-coke ingumkhiqizo okhiqizwa enkambisweni yokupheka. Ngenxa yokuthi izinhlayiya zayo zincane kakhulu, uma iqongelela esithandweni sokuqhuma, ukugeleza komoya ngeke kube bushelelezi, okuzothinta ukusebenza okuvamile kwekholomu yezinto ezisetshenziswa esithandweni sokuqhuma, futhi ngeke kuhlangabezane nezidingo ze-coke yensimbi. Ngenxa yokuthi impuphu ye-coke inezakhiwo zokuqukethwe okuphezulu kwekhabhoni, yakha izikhala zangaphakathi, kanye namandla athile, abacwaningi besayensi baseShayina benze ucwaningo olunzulu nolujulile mayelana nendlela yokusebenzisa i-coke powder eminyakeni yamuva. I-HCMilling (Guilin Hongcheng) ingumkhiqizi wei-coke yensimbiumshini wokugayaOkulandelayo yisingeniso sokusetshenziswa komshini wokugaya we-coke wensimbi:

1. I-activated carbon evela ku-metallurgical coke grinding powder: I-activated carbon iyinto yekhabhoni enesakhiwo esithuthukisiwe se-microporous kanye namandla aqinile okumunca. Isetshenziswa kabanzi emikhakheni eyahlukene njengemboni yamakhemikhali, ukucubungula ukudla, ukuvikelwa kwezempi kanye nemboni yokuvikela imvelo. Ukusebenza kwe-activated carbon kuhlobene nendawo yayo ethile, umthamo we-micropore, ukusatshalaliswa kosayizi we-pore kanye nokwakheka kwamakhemikhali. Njengamanje, izinto zokusetshenziswa eziyinhloko zokulungiselela imboni ye-activated carbon ezweni lami yizinkuni namalahle. Eminyakeni yamuva nje, ngenxa yokuntuleka kwamandla okwandayo kanye nokugcizelela kwezwe ekuvikeleni imvelo, abantu bahlala befuna ezinye izinto zokusetshenziswa zokulungiselela i-activated carbon. I-coke powder iwumkhiqizo ongaphansi kwemboni ye-coking. Inokuqukethwe okuphezulu kwekhabhoni okuqinile, okuqukethwe okuphansi kokuguquguquka kanye nomlotha, amandla aphezulu, kanye nokutholakala kalula kwezinto zokusetshenziswa. Iyinto enhle kakhulu yokulungiselela i-activated carbon. Njengamanje, i-activated carbon ikhiqizwa kakhulu ngokwelapha i-coke powder ngokusebenza ngokomzimba kanye nokusebenza kwamakhemikhali. Indlela yokusebenza ngokomzimba idinga ukuthi izinto zokusetshenziswa kumele zifakwe i-carbon ngaphambi kokusebenza, bese zisebenza ku-600 kuya ku-1200°C. I-activator ihlanganisa amagesi akhipha i-oxidation njenge-CO2 kanye nomhwamuko wamanzi, kanti ama-athomu e-carbon ezintweni ze-carbon oxide ezikhipha i-oxidation zegesi asetshenziswa ukudlula. I-activated carbon enezimbobo ezithuthukisiwe kahle yakhiwa imisebenzi yokuvula, ukwandisa nokudala izikhala ezintsha. I-activation yamakhemikhali ibhekisela ekuxubeni izinto zokusetshenziswa nama-activator (i-alkali metal kanye ne-alkali metal hydroxides, usawoti ongaphili kanye nama-acid athile) ngesilinganiso esithile, ukuwacwilisa isikhathi esithile, bese uqedela izinyathelo ze-carbonization kanye ne-activation ngesinyathelo esisodwa.

2. Ukwelashwa kwamanzi amdaka nge-metallurgical coke grinding powder: indlela yokumunca iyindlela evamile esetshenziswa ukwelapha amanzi amdaka e-coking. Ngenxa yezikhala zangaphakathi ze-coke powder ezithuthukisiwe kanye nokusebenza kahle kokumunca, abanye abacwaningi eShayina benze ucwaningo ngokuphathwa kwe-coke powder yamanzi amdaka e-coking. UZhang Jinyong usebenzisa i-coke powder evuselelwa ngumusi ukuze amunce amanzi amdaka e-biochemical avela esitshalweni sokumunca. Ngemva kokumunca, isidingo se-chemical oxygen (COD) samanzi amdaka sincishiswa kusuka ku-233mg/L kuya ku-50mg/L, sifinyelele izinga lokukhishwa kwesigaba sokuqala sikazwelonke. ULiu Xian nabanye basebenzise i-coke powder ekwelapheni kwesibili kokumunca amanzi amdaka e-coking, futhi bafunda izimo zenqubo ezifanele zokumunca i-coke powder yamanzi amdaka e-coking ngokuhlola okuqhubekayo okungaguquki nokuguquguqukayo. Imiphumela yocwaningo ikhombisa ukuthi i-COD yamanzi angcolile e-biochemical ngemva kokwelashwa kwe-coke powder okuthuthukisiwe ingancishiswa ibe ngaphansi kuka-100mg/L, kanti izinga lokususwa kwe-chromaticity lingafinyelela ngaphezu kuka-60%, okuhlangabezana nezidingo zekhwalithi yamanzi zamabhizinisi okupheka.

3. Ukwakhiwa kwempuphu yokugaya ye-coke yensimbi enezithasiselo: inqubo yempuphu ye-coke ngokwayo ayinamatheli, futhi ivame ukusetshenziswa ngokufaka i-binder kuyo ukuze icindezelwe futhi ibunjwe. Kunezinhlobo eziningi zezithasiselo zempuphu ye-coke, futhi ikhwalithi ye-coke ekhiqizwayo ayifani. ULiu Baoshan wasebenzisa i-ejenti yokuhlanganisa i-humate, i-starch waste residue, i-coal slime, i-caustic soda kanye ne-bentonite njenge-binder ukuze atadishe inani lezithasiselo, izimo zokubumba zempuphu ye-coke, ukuma nosayizi wezinhlayiya zebhola lokubumba, kanye nokushisa okomile, futhi amabhola alungisiwe ahlolwa futhi ashiswa, futhi imiphumela yabonisa ukuthi amabhola empuphu ye-coke ayenamandla amahle kanye nokuqina kokushisa, futhi angasetshenziswa ukukhiqiza igesi ngokwenziwa. UZhang Liqi wasebenzisa impuphu ye-coke kanye ne-tar residue ekhiqizwe yi-gas generator ukuxuba nokubumba ngokwesilinganiso esithile, bese i-oxidized futhi i-carbonized ukwenza i-coke ukuze i-gasification. Izakhiwo ze-coke zifinyelele ezingeni le-gasification coke. Inikeza isisekelo semfundiso yokukhiqizwa kwezimboni.

4. Impuphu yokugaya i-coke yensimbi ukukhiqiza i-coke yensimbi: i-coke powder ivame ukusetshenziswa njenge-ejenti yokunciphisa enkambisweni yokupheka. Ukwengeza i-coke powder efanele enkambisweni yokupheka kungathuthukisa ikhwalithi ye-coke. Ngenxa yokuntuleka okwandayo kwezinsizakusebenza zamalahle okupheka eShayina, ukuze kwandiswe izinsizakusebenza zamalahle okupheka futhi kuncishiswe izindleko zokuxuba amalahle, amabhizinisi amaningi okupheka azame ukusebenzisa i-coke powder njengengxenye yokuxuba amalahle okupheka ukuze kuthuthukiswe izinzuzo zomnotho ze-coke powder. Amabhizinisi amaningi eShayina enze ucwaningo ngobukhulu bezinhlayiya kanye nesilinganiso se-coke powder. UYang Mingping wenze ukuhlolwa kokukhiqiza kwezimboni ngokusekelwe ekuhlolweni kwe-coke oven encane. Imiphumela ikhombisa ukuthi ngaphansi kwezimo zenqubo yokupheka esezingeni eliphezulu evamile, kungenzeka ukwengeza u-3% kuya ku-5% wempuphu ye-coke ukuze kuthathelwe indawo amalahle angenamafutha okupheka. Izinga lebhulokhi landa, futhi izinga lokuthengiselana landa cishe ngo-3%. Ngocwaningo, uWang Dali nabanye bathole ukuthi ukupheka nge-coke powder akunawo umthelela osobala ekukhanyeni okuphezulu kwe-vitrinite yamalahle ahlanganisiwe. Kodwa-ke, ngokulinganisa okuncane kakhulu, kwatholakala ukuthi izinhlayiya ze-coke powder ezinkulu kuno-0.2mm zazizimele ku-coke, futhi kwakunzima ukuzihlanganisa nezinye izingxenye, futhi ukuma kwazo akuzange kushintshe; kuyilapho i-coke powder encane kuno-0.2mm yayisongwa kalula yi-colloid, okwakuyilungele ukwakheka kwe-coke. Ingxenye efanele ye-coke powder ingu-1.0%-1.7%, ububanzi bosayizi bezinhlayiya obuhle bungu-98%-100% ngaphansi kuka-3mm, 78%-80% ngaphansi kuka-1mm, kanye no-40%-50% ngaphansi kuka-0.2mm.

Ukugaya i-coke ngensimbi akuhlukaniseki nomshini wokugaya i-coke ngensimbi. Njengomkhiqizi womshini wokugaya i-coke ngensimbi, i-HCMilling (Guilin Hongcheng) ikhiqizai-coke yensimbi uRaymondumshini wokugaya, i-coke yensimbi okuhle kakhuluumshini wokugaya, i-coke yensimbi okuqondilei-rollerumshini wokugayakanye neminye imishini. Ingakhiqiza i-mesh 80-2500 mesh coke powder futhi inikeze ukwesekwa kobuchwepheshe kokusetshenziswa kwe-metallurgical coke grinding powder.

Uma unezidingo zomshini wokugaya i-coke wensimbi, sicela ukhululeke ukuxhumana nathi ukuthola imininingwane yemishini futhi usinikeze ulwazi olulandelayo:
