Umgubo weCoke ngumkhiqizo ophumayo oveliswa kwinkqubo yokupheka. Ngenxa yokuba amasuntswana awo mancinci kakhulu, xa eqokelelana kwi-blast furnace, ukuhamba komoya akuyi kuba lula, nto leyo eya kuchaphazela ukusebenza okuqhelekileyo kwekholamu yezinto ezikwi-blast furnace, kwaye ayinakuhlangabezana neemfuno ze-metallurgical coke. Ngenxa yokuba umgubo weCoke uneepropati zomxholo ophezulu wekhabhoni, uphuhlise iindawo zangaphakathi, kunye namandla athile, abaphandi bezenzululwazi baseTshayina benze uphando olubanzi nolunzulu malunga nendlela yokusebenzisa umgubo weCoke kwiminyaka yakutshanje. I-HCMilling (Guilin Hongcheng) ngumvelisi wei-coke yesinyithiumsi wokugayaOku kulandelayo yintshayelelo yokusetyenziswa kwe-metallurgical coke grinding mill:

1. Ikhabhoni esebenzayo evela kumgubo wokugaya we-coke osebenzisa isinyithi: Ikhabhoni esebenzayo sisixhobo sekhabhoni esinesakhiwo esiphuhlileyo se-microporous kunye namandla aqinileyo okufunxa. Isetyenziswa kakhulu kwiindawo ezahlukeneyo ezifana neshishini leekhemikhali, ukucubungula ukutya, ukhuseleko lomkhosi kunye neshishini lokukhusela okusingqongileyo. Ukusebenza kwekhabhoni esebenzayo kunxulumene nendawo yayo ethile yomphezulu, umthamo we-micropore, ukusasazwa kobukhulu be-pore kunye nokwakheka kweekhemikhali. Okwangoku, izinto eziphambili zokulungiswa kwekhabhoni esebenzayo kwilizwe lam ziinkuni namalahle. Kwiminyaka yakutshanje, ngenxa yokwanda kokunqongophala kwamandla kunye nokugxininiswa kwelizwe kukhuseleko lokusingqongileyo, abantu bahlala bekhangela ezinye izinto zokulungisa ikhabhoni esebenzayo. I-Coke powder yimveliso ephuma kwishishini lokupheka. Inomxholo ophezulu wekhabhoni ozinzileyo, umxholo ophantsi we-volatible kunye nothuthu, amandla aphezulu, kunye nokufumaneka lula kwezinto zokubhaka. Sisixhobo esibalaseleyo sokulungiselela ikhabhoni esebenzayo. Okwangoku, ikhabhoni esebenzayo iveliswa kakhulu ngokunyanga i-coke powder ngokusebenza ngokwasemzimbeni kunye nokusebenza kweekhemikhali. Indlela yokusebenza ngokwasemzimbeni ifuna ukuba izinto zokubhaka kufuneka zifakwe i-carbon ngaphambi kokuba zisebenze, kwaye emva koko zisebenze kwi-600 ukuya kwi-1200°C. I-activator iquka iigesi ezikhupha i-oxidation ezifana ne-CO2 kunye nomphunga wamanzi, kwaye ii-athomu zekhabhoni kwi-carbon oxide material yegesi zisetyenziselwa ukudlula. I-activated carbon ene-pores ephuhliswe kakuhle yenziwa yimisebenzi yokuvula, ukwandisa nokudala i-voids ezintsha. I-chemical activation ibhekisa ekuxubeni izinto eziluhlaza kunye ne-activators (i-alkali metal kunye ne-alkali metal hydroxides, iityuwa ezingaphiliyo kunye nezinye ii-asidi) ngomlinganiselo othile, ukuzintywilisela ixesha elithile, uze emva koko ugqibezele amanyathelo e-carbonization kunye ne-activation ngenyathelo elinye.

2. Unyango lwamanzi amdaka e-biochemical nge-metallurgical coke grinding powder: indlela yokufunxa yindlela eqhelekileyo esetyenziswa ukunyanga amanzi amdaka e-coking. Ngenxa yemingxunya yangaphakathi ephuhlisiweyo ye-coke powder kunye nokusebenza kakuhle kokufunxa, abanye abaphandi eTshayina benze uphando malunga nokufunxa amanzi amdaka e-coking powder. UZhang Jinyong usebenzisa i-coke powder evuselelwa ngumphunga ukufunxa amanzi amdaka e-biochemical kwisityalo sokufunxa. Emva kokufunxa, imfuno ye-oxygen yekhemikhali (COD) yamanzi amdaka iyancipha ukusuka kwi-233mg/L ukuya kwi-50mg/L, ifikelela kumgangatho wokuqala wokukhupha wesizwe. ULiu Xian nabanye basebenzise i-coke powder kunyango lwesibini lokufunxa amanzi amdaka e-coking, kwaye bafunda iimeko ezifanelekileyo zenkqubo yokufunxa amanzi amdaka e-coke powder ngezilingo eziqhubekayo ezizinzileyo nezinamandla. Iziphumo zophando zibonisa ukuba i-COD yamanzi amdaka e-biochemical emva konyango oluphambili lwe-coke powder ingancitshiswa ibe ngaphantsi kwe-100mg/L, kwaye izinga lokususwa kwe-chromaticity lingafikelela ngaphezulu kwe-60%, nto leyo ehlangabezana neemfuno zomgangatho wamanzi zamashishini e-coking.

3. Ukwenziwa komgubo wokugaya we-coke we-metallurgical kunye nezongezo: inkqubo yomgubo we-coke ngokwayo ayinamatheli, kwaye idla ngokusetyenziswa ngokongeza i-binder kuyo ukuze icinezelwe kwaye yenziwe. Kukho iintlobo ezininzi zezongezo ze-coke powder, kwaye umgangatho we-coke eveliswayo awufani. ULiu Baoshan usebenzise i-compounding agent ye-humate, i-starch waste residue, i-coal slime, i-caustic soda kunye ne-bentonite njenge-binder ukuze afunde ubungakanani bezongezo, iimeko zokubumba ze-coke powder, imo kunye nobukhulu be-particle yebhola yokubumba, kunye nobushushu bokomisa, kwaye iibhola ezilungisiweyo zavavanywa kwaye zatshiswa, kwaye iziphumo zabonisa ukuba iibhola ze-coke powder zazinamandla amahle kunye nozinzo lobushushu, kwaye zinokusetyenziselwa ukuvelisa igesi ngokwenziwa. UZhang Liqi wasebenzisa umgubo we-coke kunye ne-tar residue eveliswe yijenereyitha yegesi ukuxuba kunye nokubumba ngokwemilinganiselo ethile, emva koko i-oxidized kunye ne-carbonized ukwenza i-coke ukuze ifake igesi. Iimpawu ze-coke zifikelele kumgangatho we-gasification coke. Inika isiseko sethiyori semveliso yemizi-mveliso.

4. Umgubo wokugaya we-coke osebenzisa i-metallurgical ukuvelisa i-coke ye-metallurgical: umgubo we-coke uhlala usetyenziswa njenge-arhente yokuncitshiswa kwinkqubo yokupheka. Ukongeza umgubo we-coke ofanelekileyo kwinkqubo yokupheka kunokuphucula umgangatho we-coke. Ngenxa yokunqongophala okwandayo kwezixhobo zamalahle okupheka eTshayina, ukuze kwandiswe izixhobo zamalahle okupheka nokunciphisa iindleko zokuxuba amalahle, amashishini amaninzi okupheka azame ukusebenzisa umgubo we-coke njengenxalenye yokuxuba amalahle okupheka ukuphucula iingenelo zoqoqosho ze-coke powder. Amashishini amaninzi eTshayina enze uphando ngobukhulu bamasuntswana kunye nomlinganiselo we-coke powder. UYang Mingping wenze uvavanyo lwemveliso yemizi-mveliso ngokusekelwe kuvavanyo lwe-coke oven encinci. Iziphumo zibonisa ukuba phantsi kweemeko zenkqubo yokupheka ephezulu eqhelekileyo, kunokwenzeka ukongeza i-3% ukuya kwi-5% ye-coke powder endaweni yelahle elithambileyo lokupheka. Inqanaba lebhloko landa, kwaye izinga lokuthengiselana landa malunga ne-3%. Ngophando, uWang Dali nabanye bafumanise ukuba ukupheka nge-coke powder akunampembelelo icacileyo ekubonakalisweni okuphezulu kwe-vitrinite yamalahle axutyiweyo. Nangona kunjalo, ngokulinganisa ngemicroscope, kwafunyaniswa ukuba amasuntswana e-coke powder amakhulu kune-0.2mm ayezimele kwi-coke, kwaye kwakunzima ukuwadibanisa nezinye izinto, kwaye imo ayizange itshintshe; ngelixa i-coke powder encinci kune-0.2mm yayisongelwe lula yi-colloid, nto leyo eyayilungele ukwenziwa kwe-coke. Umlinganiselo ofanelekileyo we-coke powder yi-1.0%-1.7%, uluhlu lobukhulu be-particle oluphezulu yi-98%-100% ngaphantsi kwe-3mm, i-78%-80% ngaphantsi kwe-1mm, kunye ne-40%-50% ngaphantsi kwe-0.2mm.

Ukugaya i-coke nge-metallurgical akunakwahlulwa kwi-metallurgical coke grinding mill. Njengomvelisi we-metallurgical coke grinding mill, i-HCMilling (Guilin Hongcheng) ivelisai-coke yesinyithi uRaymondumsilo, i-coke yesinyithi icoceke kakhuluumsilo, i-coke yesinyithi ngokuthe nkqoirolaumsilokunye nezinye izixhobo. Ingavelisa umgubo we-coke metallurgical one-mesh ezingama-80-2500 kwaye inike inkxaso yobugcisa ekusebenziseni umgubo wokugaya we-coke metallurgical.

Ukuba uneemfuno zomatshini wokugaya i-coke wesinyithi, nceda uzive ukhululekile ukunxibelelana nathi ukuze ufumane iinkcukacha zezixhobo kwaye usinike ulwazi olulandelayo:
