I-coke powder ingumkhiqizo okhiqizwa ohlelweni lokupheka.Ngenxa yokuthi izinhlayiya zayo zincane kakhulu, lapho zinqwabelana esithandweni somlilo, ukugeleza komoya ngeke kube bushelelezi, okuzothinta ukusebenza okuvamile kwekholomu yezinto esithandweni somlilo, futhi ayikwazi ukuhlangabezana nezidingo ze-coke ye-metallurgical.Ngenxa yokuthi i-coke powder inezici zokuqukethwe kwekhabhoni ephezulu, ithuthukiswe i-voids yangaphakathi, namandla athile, abacwaningi besayensi baseShayina baye benza ucwaningo olunzulu nolujulile mayelana nendlela yokusebenzisa i-coke powder eminyakeni yamuva.I-HCMilling(Guilin Hongcheng) ingumkhiqizi wei-coke ye-metallurgicalumshini wokugaya.Okulandelayo yisingeniso sokusetshenziswa kwe-metallurgical coke grinding mill:

1. Ikhabhoni ecushiwe evela ku-coke ye-metallurgical yokugaya impushana: Ikhabhoni ecushiwe iyisisetshenziswa sekhabhoni esinesakhiwo se-microporous esithuthukisiwe kanye nomthamo oqinile we-adsorption.Isetshenziswa kabanzi emikhakheni ehlukahlukene efana nemboni yamakhemikhali, ukucubungula ukudla, ukuvikelwa kwezempi kanye nomkhakha wokuvikela imvelo.Ukusebenza kwekhabhoni ecushiwe kuhlobene nendawo yayo ethile, umthamo we-micropore, ukusatshalaliswa kosayizi wezimbotshana kanye nokwakheka kwamakhemikhali.Njengamanje, izinto zokusetshenziswa eziyinhloko zokulungiswa kwezimboni zekhabhoni ecushiwe ezweni lami ziyizinkuni namalahle.Eminyakeni yamuva, ngenxa yokuntuleka kwamandla okwandayo kanye nokugcizelela kwezwe ekuvikelweni kwemvelo, abantu bahlale befuna ezinye izinto zokusetshenziswa zokulungiselela ikhabhoni ecushiwe.I-coke powder iwumkhiqizo ovela embonini yokupheka.Inokuqukethwe okuphezulu kwekhabhoni engaguquki, ukuguquguquka okuphansi kanye nokuqukethwe komlotha, amandla aphezulu, nokutholakala kalula kwezinto zokusetshenziswa.Kuyimpahla enhle kakhulu yokulungiselela ikhabhoni ecushiwe.Njengamanje, ikhabhoni ecushiwe ikhiqizwa ikakhulukazi ngokuphatha i-coke powder ngokwenza kusebenze ngokomzimba kanye nokusebenza kwamakhemikhali.Indlela yokwenza kusebenze ngokomzimba idinga ukuthi izinto zokusetshenziswa kufanele zenziwe ikhabhoni ngaphambi kokuba zisebenze, bese zicushwa ku-600 kuya ku-1200°C.I-activator ihlanganisa amagesi e-oxidizing afana ne-CO2 nomhwamuko wamanzi, futhi ama-athomu ekhabhoni asendaweni ye-oxidizing carbon oxide yegesi asetshenziselwa ukudlula.Ikhabhoni ecushiwe enama-pores athuthuke kahle yenziwa imisebenzi yokuvula, yokwandisa nokudala ama-voids amasha.Ukwenza kusebenze amakhemikhali kubhekisela ekuhlanganiseni izinto zokusetshenziswa nezisetshenziswa (insimbi ye-alkali nama-alkali metal hydroxides, usawoti we-inorganic kanye nama-acid athile) ngesilinganiso esithile, ukucwiliswa isikhathi esithile, bese uqedela izinyathelo ze-carbonization nezokuvula ngesinyathelo esisodwa.

2. Ukwelashwa kwamanzi angcolile amakhemikhali ezinto eziphilayo nge-metallurgical coke grinding powder: indlela ye-adsorption iyindlela evamile esetshenziselwa ukwelapha amanzi angcolile e-coking.Ngenxa ye-voids yangaphakathi ethuthukisiwe ye-coke powder nokusebenza okuhle kwe-adsorption, abacwaningi abathile e-China baye benza ucwaningo mayelana nokwelashwa kwe-coke powder emanzini angcolile.U-Zhang Jinyong usebenzisa i-coke powder ecushwe isitimu ukuze adsorbe amanzi angcolile amakhemikhali e-biochemical asuka esitshalweni sokubhaka.Ngemva kokukhangiswa, isidingo sekhemikhali komoyampilo (COD) samanzi angcolile siyehla sisuka ku-233mg/L siye ku-50mg/L, sifinyelele izinga lokukhishwa lezinga lokuqala likazwelonke.U-Liu Xian et al.wasebenzisa i-coke powder ekwelapheni kwe-adsorption yesibili yamanzi angcolile okupheka, futhi wafunda izimo zenqubo efanele ye-coke powder adsorption yamanzi angcolile e-coking ngokuhlola okuqhubekayo okuqinile nokunamandla.Imiphumela yocwaningo ibonisa ukuthi i-COD yamanzi angcolile e-biochemical ngemva kokwelashwa okuthuthukisiwe kwe-coke powder ingancishiswa ibe ngaphansi kwe-100mg / L, futhi izinga lokususwa kwe-chromaticity lingafinyelela ngaphezu kwe-60%, elihlangabezana nezidingo zekhwalithi yamanzi zamabhizinisi okupheka.

3. Ukwakhiwa kwe-coke ye-metallurgical yokugaya i-powder enezithasiselo: inqubo ye-coke powder ngokwayo ayinakho ukunamathela, futhi ivame ukusetshenziswa ngokungeza i-binder kuyo ukuze ucindezele futhi wenze.Kunezinhlobo eziningi zezithasiselo ze-coke powder, futhi izinga le-coke elikhiqizwayo alifani.U-Liu Baoshan wasebenzisa i-agent ehlanganisayo ye-humate, insalela yemfucumfucu yesitashi, i-slime yamalahle, i-caustic soda ne-bentonite njengesibophezelo ukuze ahlole inani lezithasiselo, izimo zokubumba ze-coke powder, ukwakheka nosayizi wezinhlayiyana zebhola elibunjwayo, nokomiswa. izinga lokushisa, kanye namabhola alungisiwe ahlolwe futhi axoshwa, futhi imiphumela yabonisa ukuthi amabhola e-coke powder ayenamandla amahle nokuzinza okushisayo, futhi angasetshenziselwa ukukhiqiza igesi ngokuzenzakalelayo.U-Zhang Liqi wasebenzisa impushana ye-coke kanye nensalela yetiyela ekhiqizwa ijeneretha yegesi ukuze axube futhi alolonge ngokwengxenye ethile, wabe esefakwa i-oxidized kanye ne-carbonized ukuze enze i-coke ye-gasification.Izakhiwo ze-coke zifinyelele izinga le-coke ye-gasification.Ihlinzeka ngesisekelo sethiyori sokukhiqizwa kwezimboni.

4. I-coke ye-Metallurgical yokugaya i-powder ukukhiqiza i-coke ye-metallurgical: i-coke powder ivame ukusetshenziswa njenge-ejenti yokunciphisa inqubo yokupheka.Ukwengeza i-coke powder efanelekile enqubweni yokupheka kungathuthukisa ikhwalithi ye-coke.Ngenxa yokushoda okwandayo kwezinsiza zamalahle okuphekela eChina, ukuze kwandiswe izinsiza zamalahle futhi kuncishiswe izindleko zokuhlanganisa amalahle, amabhizinisi amaningi okupheka aye azama ukusebenzisa i-coke powder njengengxenye yokuhlanganisa amalahle ekuphekeni ukuze kuthuthukiswe izinzuzo zezomnotho ze-coke. impushana.Amabhizinisi amaningi e-China enze ucwaningo ngosayizi wezinhlayiyana kanye nengxenye ye-coke powder.U-Yang Mingping wenze ukuhlolwa kokukhiqizwa kwezimboni ngesisekelo sokuhlolwa kwe-oven ye-coke encane.Imiphumela ibonisa ukuthi ngaphansi kwezimo ezivamile zenqubo yokulayisha phezulu, kungenzeka ukwengeza u-3% kuya ku-5% we-coke powder esikhundleni samalahle amancane ukuze apheke.I-block degree yanda, futhi izinga lokuthengiselana landa cishe ngo-3%.Ngocwaningo, u-Wang Dali et al.ithole ukuthi ukupheka nge-coke powder akunawo umphumela ocacile ekuboniseni okuphezulu kwe-vitrinite yamalahle ahlanganisiwe.Kodwa-ke, ngokulinganisa okuncane kakhulu, kutholakale ukuthi izinhlayiya ze-coke powder ezinkulu kune-0.2mm zazizimele ku-coke, futhi kwakunzima ukuhlanganisa nezinye izingxenye, futhi ukubunjwa akuzange kushintshe;kuyilapho i-coke powder encane kuno-0.2mm isongwe kalula nge-colloid, eyayilungele ukwakheka kwe-coke.Ingxenye efanelekile ye-coke powder ingu-1.0% -1.7%, ububanzi besayizi wezinhlayiyana obulungile bungama-98% -100% ngaphansi kuka-3mm, 78% -80% ngaphansi kuka-1mm, futhi 40% -50% ngaphansi kuka-0.2mm.

Ukugaya i-coke ye-Metallurgical akunakuhlukaniswa nesigayo sokugaya i-coke ye-metallurgical.Njengomkhiqizi we-metallurgical coke grinding mill, i-HCMilling(Guilin Hongcheng) ikhiqizai-coke ye-metallurgical Raymondisigayo, i-coke ye-metallurgical ultra-fineisigayo, i-coke ye-metallurgical mporollerisigayonezinye izinto zokusebenza.Ingakhiqiza i-80-2500 mesh metallurgical coke powder futhi inikeze ukwesekwa kwezobuchwepheshe ekusetshenzisweni kwe-metallurgical coke grinding powder.

Uma unezidingo zokugaya i-coke grinding mill, sicela ukhululeke ukuxhumana nathi ukuze uthole imininingwane yesisetshenziswa futhi usinikeze imininingwane elandelayo:
