I-Coke powder ngumkhiqizo owenziwe ngenqubo yokukhangisa. Ngoba izinhlayiya zayo zincane kakhulu, lapho ziqongelela esithandweni sokuqhuma, ukugeleza komoya ngeke kubushelelezi, okuzothinta ukusebenza okujwayelekile kwekholomu ye-blast, futhi ngeke kuhlangabezane nezidingo ze-metallurgical coke. Ngoba i-Coke powder inezakhiwo zokuqukethwe okuphezulu kwekhabhoni, athuthukise izikhala zangaphakathi, namandla athile, abacwaningi besayensi baseChina benze ucwaningo olubanzi futhi olujulile lokuthi ungayisebenzisa kanjani i-Coke powder eminyakeni yamuva. I-HCMILLILING (Guilin Hongcheng) ngumenzi weI-Metallurgical Cokeukugaya umgodi. Okulandelayo ukungeniswa kokusetshenziswa kwe-metallurgical coke yokugaya umgodi:

1. I-Carbon yasebenza isebenze kusuka powder ye-metallurgical coke yokugaya Isetshenziswa kabanzi emikhakheni ehlukahlukene efana nemboni yamakhemikhali, ukucubungula ukudla, ukuvikelwa kwamasosha kanye nomkhakha wokuvikela imvelo. Ukusebenza kwekhabhoni esetshenzisiwe kuhlobene nendawo yayo eqondile yangaphezulu, ivolumu ye-micropore, ukusatshalaliswa kosayizi we-pore kanye nokwakheka kwamakhemikhali. Njengamanje, izinto eziphambili ezingavuthiwe zokulungiswa kwezimboni zekhabhoni eyenziwe nge-Carbon ezweni lami izinkuni namalahle. Eminyakeni yamuva nje, ngenxa yokukhula okwandayo kwamandla nokugcizelelwa kwezwe ekuvikelweni kwemvelo, abantu bahlala befuna ezinye izinto eziluhlaza zokulungiselela ikhabhoni eyenziwe. I-Coke powder ingumkhiqizo womkhakha we-coking. Inokuqukethwe okuphezulu kwekhabhoni, okuqukethwe okuguquguqukayo okuvuthayo kanye nomlotha, amandla aphezulu, nokutholakala kalula kwezinto zokusetshenziswa. Kuyinto enhle kakhulu yokulungiselela ikhabhoni esetshenzisiwe. Njengamanje, i-carbon esetshenzisiwe ikhiqizwa ikakhulukazi ngokuphatha i-coke powder ngokusebenza ngokomzimba kanye nokwenza kusebenze amakhemikhali. Indlela yokusebenza ngokomzimba idinga ukuthi izinto ezingavuthiwe kufanele zibe yi-carbonised ngaphambi kokwenza kusebenze, bese zisebenza ngo-600 kuya ku-1200 ° C. Isishoshovu sifaka amagesi oxidizing anjenge-CO2 kanye ne-vapor yamanzi, namathomu e-carbon ku-oxidizing carbon oxide impahla yegesi yegesi isetshenziselwa ukudlula. Ikhabhoni eyenziwe yasebenza nge-pores ethuthukiswe kahle yakhiwa yimisebenzi yokuvula, ukunwebeka nokwakha izikhala ezintsha. I-Chemical activation isho ukuxuba izinto ezisetshenziswayo ezinama-activators (i-alkali yensimbi kanye ne-alkali metal hydroxides, usawoti we-inorganic kanye nama-acid athile) ngesilinganiso esithile, bese ugcwalisa izinyathelo ze-carbonization kanye nezinyathelo zokwenza kusebenze ngesinyathelo esisodwa.

2 Ngenxa yama-overcent akhiqizwayo we-coke powder kanye nokusebenza okuhle kwe-adsorption, abanye abacwaningi eChina baye benza ucwaningo ngokwelashwa kweCoke Posking yamanzi angcolile. UZhang Jinyong usebenzisa i-Coke poda ecutshungulwe nguSteam kuya ku-adsorb biochemical waschemical wastewater kusuka ku-Coking Plant. Ngemuva kwe-adsorption, isidingo se-oxygen chemin (i-cod) yamanzi angcolile ancishisiwe kusuka ku-233mg / l kuya ku-50mg / L, ukufinyelela ekilasini likazwelonke lokuphuma. U-Liu Xian et al. Kusetshenziswe i-Coke powder yokwelashwa kwama-adsorption wesibili wamanzi angcolile, futhi wafunda izimo ezifanele zenqubo ye-coke powder adsorption yamanzi angcolile ashubile. Imiphumela yocwaningo ikhombisa ukuthi i-Cod yamanzi angcolile we-biochemical ngemuva kokulashwa kwe-coke powder ethuthukile ingancishiswa ibe ngaphansi kwe-100mg / L, futhi isilinganiso sokususa i-chromatic singafinyelela ngaphezu kwama-60%, okuhlangabezana nezidingo zekhwalithi yamanzi amabhizinisi okukhokhi.

I-3. Ukwakheka kwe-metallurgical coke yokugaya ngezengezo: Inqubo ye-coke powder ngokwayo ayinakho ukunamathela, futhi kuvame ukusetshenziswa ngokungeza i-tinder kuyo ukucindezela nokwakha. Kunezinhlobo eziningi zezithasiselo ze-Coke powder, futhi ikhwalithi ye-coke ekhiqizwayo ayifani. U-Liu Bayan wasebenzisa i-ejenti ehlanganisiwe yokuthonya, inkanyezi yemfucumfucu ye-starch, i-caal slime, i-bentonite njenge-birnerite yokufunda inani lezengezo, izimo zokubumba ze-coke powder, kanye nokomiswa Ukushisa, futhi amabhola alungiselelwe ahlolwa futhi adutshulwe, futhi imiphumela yabonisa ukuthi amabhola e-coke powder ayenamandla amahle futhi afudumele Ukuqina, futhi kungasetshenziselwa ukukhiqiza igesi ngobuciko. UZhang Liqi wasebenzisa i-coke powder kanye nezinsalela ze-tar ezikhiqizwe generator wegesi ukuxuba nokwakheka ngokuya ngengxenye ethile, bese kuthi i-oxidized futhi i-carbonised ukwenza i-coke ye-soke. Izakhiwo ze-coke zifinyelele ezingeni le-coke yokusatshalaliswa kwendawo. Inikeza isisekelo sethiyori sokukhiqizwa kwezimboni.

I-4. I-Metallurgical Coke egayiwe i-powder yokukhiqiza i-metallurgical coke: I-Coke powder ivame ukusetshenziswa njenge-ejenti ethambile kwinqubo yokukhwehlela. Ukungeza i-Coke powder efanelekile kwinqubo yokukhangisa kungathuthukisa ikhwalithi ye-coke. Ngenxa yokushoda okwandayo kwezinsizakusebenza zamalahle eChina, ukuze kukhulise izindleko zokuhlanganiswa kwamalahle, ukunciphisa izindleko zokuhlanganiswa kwamalahle, amabhizinisi amaningi aqhakazile azamile ukusebenzisa i-Coke poking ukuze athuthukise izinzuzo zezomnotho zeCoke i-powder. Amabhizinisi amaningi eChina aqhubekile ucwaningo ngosayizi wezinhlayiyana kanye nesilinganiso se-coke powder. I-Yang mingping yenze ukuhlolwa kokukhiqizwa kwezimboni ngesisekelo sokuhlolwa kwesivinini esincane se-coke. Imiphumela ikhombisa ukuthi ngaphansi kwezimo zenqubo ezijwayelekile zokulayisha eziphezulu, kungenzeka ukwengeza ama-3% kuya ku-5% we-coke poal ukuze ungene esikhundleni se-lean coking. I-block degree iyanda, futhi izinga lokuthenga lenyuka cishe nge-3%. Ngokucwaninga, wang dali et al. Kutholakale ukuthi ukukhwehlela nge-coke powder akunamphumela osobala ekubonisweni okuphezulu kwe-vitrinite yamalahle ahlanganisiwe. Kodwa-ke, ngokulinganisa ama-microscopic, kwatholakala ukuthi izinhlayiya ze-coke powder ezinkulu kune-0.2mm ezimele zizimele eCoke, futhi bekunzima ukuhlanganisa nezinye izinto, futhi ukwakheka akuzange kuguquke; Ngenkathi i-coke powder incane kune-0.2mm embozwe kalula nge-colloid, eyayiyilungele ukwakheka kweCoke. Ingxenye efanelekile ye-Coke powder iyi-1.0% -1.7%, i-application efanelekile yobukhulu bama-98% -100% ngaphansi kwama-3mm, 78% -80% ngaphansi kwe-1mm.

Ukugaya kwe-metallurgical coke akuhlukaniswa kusuka ku-metallur coke yokugaya umgodi. Njengomenzi we-metallurgical coke yokugaya umgodi, i-HCMILLILING (Guilin Hongcheng) ikhiqizaI-Metallurgical Coke URaymondgaya ngomshini, I-Metallurgical Coke I-Ultra-Filegaya ngomshini, I-Metallurgical Coke -mile thwiokokumbazagaya ngomshinineminye imishini. Kungakhiqiza ama-80-2500 mesh metallurgical coke powder futhi anikeze ukwesekwa kwezobuchwepheshe kokusetshenziswa kwe-metallurgical coke gquingling powder.

Uma unezidingo ze-metallurgical coke yokugaya isigayo, sicela ukhululeke ukuxhumana nathi ngemininingwane yemishini futhi unikeze ngolwazi lokulandela:
