I-coke powder yimveliso eveliswa kwinkqubo yokupheka.Ngenxa yokuba iincinci zayo zincinci kakhulu, xa ziqokelela kwisithando somlilo, ukuhamba komoya akuyi kuba lula, okuya kuchaphazela ukusebenza okuqhelekileyo kwekholamu yezinto kwisithando somlilo, kwaye ayikwazi ukuhlangabezana neemfuno ze-coke metallurgical.Ngenxa yokuba i-coke powder ineempawu zekhabhoni ephezulu, iphuhliswe i-voids yangaphakathi, kunye namandla athile, abaphandi bezenzululwazi baseTshayina baye benza uphando olunzulu kunye nolunzulu malunga nendlela yokusebenzisa i-coke powder kwiminyaka yamuva.HCMilling(Guilin Hongcheng) ngumvelisi wecoke metallurgicalilitye lokusila.Oku kulandelayo sintshayelelo ekusetyenzisweni kwelitye lokusila i-coke ye-metallurgical:

1. Ikhabhoni esebenzayo kwi-coke ye-metallurgical yokugaya i-powder: I-carbon activated yi-carbon material ene-microporous structure kunye ne-adsorption eqinile.Isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana neshishini lemichiza, ukusetyenzwa kokutya, ukukhuselwa komkhosi kunye noshishino lokusingqongileyo.Ukusebenza kwekhabhoni esebenzayo kuhambelana nommandla wayo othile, umthamo we-micropore, ukusabalalisa ubungakanani bepore kunye nokwakheka kweekhemikhali.Okwangoku, izinto eziphambili zokulungiswa kweshishini lekhabhoni esebenzayo kwilizwe lam ziinkuni kunye namalahle.Kwiminyaka yakutshanje, ngenxa yokunqongophala kwamandla okwandayo kunye nogxininiso lwelizwe ekukhuselweni kwendalo, abantu bahlala bekhangela izinto ezizezinye zokulungiselela i-carbon activated.I-coke powder yimveliso yemveliso yokupheka.Inomxholo ophezulu wekhabhoni esisigxina, i-volatile ephantsi kunye nomxholo wothuthu, amandla aphezulu, kunye nokufumaneka lula kwezinto eziluhlaza.Yimpahla egqwesileyo yokulungiselela ikhabhoni esebenzayo.Okwangoku, i-carbon activated iveliswa ikakhulu ngokuphatha i-coke powder ngokusebenza ngokomzimba kunye nokusebenza kweekhemikhali.Indlela yokuvula ngokwasemzimbeni ifuna ukuba imathiriyeli ekrwada kufuneka ifakwe ikharbhoni phambi kokuba isebenze, emva koko isebenze kwi-600 ukuya kwi-1200°C.I-activator iquka i-oxidizing gases ezifana ne-CO2 kunye nomphunga wamanzi, kunye ne-athomu ye-carbon kwi-oxidizing carbon oxide material yegesi isetyenziselwa ukudlula.Ikhabhoni esebenzayo ene-pores ephuhliswe kakuhle yenziwa yimisebenzi yokuvula, ukwandisa kunye nokudala i-voids entsha.Ukusebenza kweMichiza kubhekiselele ekuxubeni izinto eziluhlaza kunye ne-activators (isinyithi sealkali kunye ne-alkali metal hydroxides, iityuwa ze-inorganic kunye nezinye ii-asidi) kumlinganiselo othile, ukuntywiliselwa ixesha elithile, kwaye emva koko ukugqiba i-carbonization kunye namanyathelo okusebenza kwinqanaba elinye.

2. Ukunyangwa kwamanzi amdaka e-biochemical nge-metallurgical coke grinding powder: indlela ye-adsorption yindlela eqhelekileyo esetyenziselwa ukunyanga amanzi amdaka e-coking.Ngenxa ye-voids yangaphakathi ephuhlisiwe ye-coke powder kunye nokusebenza kakuhle kwe-adsorption, abanye abaphandi baseTshayina baye benza uphando malunga nonyango lwe-coke powder yokucoca amanzi amdaka.UZhang Jinyong usebenzisa umgubo wecoke ovulwe ngumphunga ukuze adsorb amanzi amdaka e-biochemical asuka kwiplanti yokupheka.Emva kwe-adsorption, imfuno ye-oksijini yeekhemikhali (COD) yamanzi amdaka iyancipha ukusuka kwi-233mg / L ukuya kwi-50mg / L, ifikelele kumgangatho wokukhutshwa kweklasi yokuqala.ULiu Xian et al.wasebenzisa i-coke powder kunyango lwesibini lwe-adsorption yokucoca amanzi amdaka, kwaye wafunda iimeko ezifanelekileyo zenkqubo ye-coke powder adsorption yamanzi amdaka e-coking ngovavanyo oluzinzileyo kunye noluguquguqukayo oluqhubekayo.Iziphumo zophando zibonisa ukuba i-COD yamanzi amdaka e-biochemical emva kokunyangwa kwe-coke powder ephezulu ingancitshiswa ibe ngaphantsi kwe-100mg / L, kwaye izinga lokususwa kwe-chromaticity linokufikelela ngaphezu kwe-60%, ehlangabezana neemfuno zomgangatho wamanzi kumashishini okupheka.

3. Ukuqulunqwa kwe-coke ye-metallurgical yokugaya i-powder kunye ne-additives: inkqubo ye-coke powder ngokwayo ayinayo i-adhesiveness, kwaye idla ngokusetyenziswa ngokudibanisa i-binder kuyo ngokucofa kunye nokwenza.Kukho iintlobo ezininzi zezongezo ze-coke powder, kwaye umgangatho we-coke oveliswayo awufani.U-Liu Baoshan usebenzise i-agent edibanisayo ye-humate, intsalela yenkunkuma ye-starch, i-slime yamalahle, i-caustic soda kunye ne-bentonite njengesibophelelo sokufunda ubungakanani bezongezo, iimeko zokubumba ze-coke powder, ukumila kunye nobukhulu beqhekeza lebhola lokubumba, kunye nokomisa. lobushushu, kunye Iibhola ezilungisiweyo zavavanywa kwaye zagxothwa, kwaye iziphumo zabonisa ukuba iibhola ze-coke ze-powder zazinamandla amahle kunye nokuzinza kwe-thermal, kwaye zingasetyenziselwa ukuvelisa igesi ngokuzenzekelayo.U-Zhang Liqi wasebenzisa i-coke powder kunye ne-tar residue eveliswa yi-generator yegesi ukuxuba kunye nokubumba ngokomlinganiselo othile, kwaye emva koko i-oxidized kunye ne-carbonized ukwenza i-coke ye-gasification.Iipropati ze-coke zifikelele kumgangatho we-coke ye-gasification.Ibonelela ngesiseko sethiyori kwimveliso yeshishini.

4. I-Metallurgical coke yokugaya i-powder ukuvelisa i-coke ye-metallurgical: i-coke powder idla ngokusetyenziswa njenge-ejenti encinci kwinkqubo yokupheka.Ukongeza i-coke powder efanelekileyo kwinkqubo yokupheka kunokuphucula umgangatho we-coke.Ngenxa yokunqongophala kwemithombo yamalahle e-coking e-China, ukuze kwandiswe izixhobo zamalahle kunye nokunciphisa iindleko zokudibanisa amalahle, amashishini amaninzi okupheka aye azama ukusebenzisa i-coke powder njengenxalenye yokudibanisa amalahle ekuphekeni ukuphucula izibonelelo zoqoqosho ze-coke. umgubo.Amashishini amaninzi e-China aqhube uphando malunga nobukhulu be-particle kunye nomlinganiselo we-coke powder.U-Yang Mingping wenze uvavanyo lwemveliso yemizi-mveliso ngokwesiseko sovavanyo oluncinci lwe-oven ye-coke.Iziphumo zibonisa ukuba phantsi kweemeko eziqhelekileyo zenkqubo yokulayisha phezulu, kunokwenzeka ukuba ungeze i-3% ukuya kwi-5% ye-coke powder ukuze ithathe indawo yelahle enqabileyo yokupheka.Idigri yebhloko yanda, kwaye izinga lokuthengiselana landa malunga ne-3%.Ngophando, uWang Dali et al.ufumene ukuba ukupheka nge-coke powder akunampembelelo ecacileyo kwi-reflection ephezulu ye-vitrinite yamalahle adibeneyo.Nangona kunjalo, ngokulinganisa kwe-microscopic, kwafunyaniswa ukuba i-coke powder particles enkulu kune-0.2mm yayizimele kwi-coke, kwaye kwakunzima ukudibanisa namanye amacandelo, kwaye imilo ayizange iguquke;ngelixa i-coke powder encinci kune-0.2mm isongelwe ngokulula nge-colloid, eyayilungele ukwenziwa kwe-coke.Umlinganiselo ochanekileyo we-coke powder ngu-1.0% -1.7%, uluhlu oluchanekileyo lwesayizi ye-particle ngu-98% -100% ngaphantsi kwe-3mm, 78% -80% ngaphantsi kwe-1mm, kunye ne-40% -50% ngaphantsi kwe-0.2mm.

Ukugaya i-coke ye-Metallurgical ayinakwahlulwa kwi-metallurgical coke grinding mill.Njengomvelisi wentsimbi yokusila icoke yokusila, iHCMilling(Guilin Hongcheng) ivelisacoke metallurgical Raymondilitye lokusila, coke metallurgical igqibeleleilitye lokusila, coke metallurgical nkqoirolailitye lokusilakunye nezinye izixhobo.Inokuvelisa i-80-2500 mesh metallurgical coke powder kunye nokubonelela ngenkxaso yobugcisa bokusetyenziswa kwe-metallurgical coke grinding powder.

Ukuba uneemfuno ze-metallurgical coke grinding Mill, nceda uzive ukhululekile ukuqhagamshelana nathi ngeenkcukacha zezixhobo kwaye unikezele ngolwazi olulandelayo kuthi:
