Foda Coke wani abu ne da ake samarwa a cikin tsarin coke. Saboda ƙwayoyinta sun yi ƙanƙanta, idan suka taru a cikin tanderun fashewa, iskar ba za ta yi laushi ba, wanda zai shafi yadda ake gudanar da ginshiƙin abu a cikin tanderun fashewa, kuma ba zai iya biyan buƙatun coke na ƙarfe ba. Saboda foda coke yana da kaddarorin yawan carbon, ƙarancin gurɓataccen ciki, da kuma wani ƙarfi, masu binciken kimiyya na ƙasar Sin sun gudanar da bincike mai zurfi kan yadda ake amfani da foda coke a cikin 'yan shekarun nan. HCMilling (Guilin Hongcheng) kamfani ne da ke kera shicoke na ƙarfeniƙa niƙaGa gabatarwar da ke ƙasa game da amfani da injin niƙa coke na ƙarfe:

1. Carbon da aka kunna daga foda niƙa na coke na ƙarfe: Carbon da aka kunna abu ne na carbon wanda ke da tsarin microporous mai ƙarfi da ƙarfin sha. Ana amfani da shi sosai a fannoni daban-daban kamar masana'antar sinadarai, sarrafa abinci, kariyar soja da masana'antar kare muhalli. Ayyukan carbon da aka kunna yana da alaƙa da takamaiman yankin saman sa, girman micropore, rarraba girman rami da kuma haɗin sinadarai. A halin yanzu, manyan kayan da ake amfani da su wajen shirya carbon da aka kunna a masana'antu a ƙasata sune itace da kwal. A cikin 'yan shekarun nan, saboda ƙaruwar ƙarancin makamashi da kuma yadda ƙasar ke mai da hankali kan kare muhalli, mutane suna ci gaba da neman madadin kayan da ake amfani da su don shirya carbon da aka kunna. Foda Coke wani samfuri ne na masana'antar coking. Yana da yawan carbon da aka gyara, ƙarancin iskar gas da toka, ƙarfi mai yawa, da sauƙin samun kayan da aka kunna. Abu ne mai kyau don shirya carbon da aka kunna. A halin yanzu, carbon da aka kunna galibi ana samar da shi ta hanyar magance foda coke ta hanyar kunna jiki da kunna sinadarai. Hanyar kunna jiki tana buƙatar cewa kayan da aka kunna dole ne a haɗa su da carbon kafin kunnawa, sannan a kunna su a zafin 600 zuwa 1200°C. Mai kunna ya haɗa da iskar gas mai hana iskar oxygen kamar CO2 da tururin ruwa, kuma ana amfani da ƙwayoyin carbon a cikin kayan iskar carbon mai hana iskar oxygen na iskar don wucewa ta cikinta. Ana samar da carbon mai kunnawa tare da ramuka masu kyau ta hanyar ayyukan buɗewa, faɗaɗawa da ƙirƙirar sabbin ramuka. Kunna sinadarai yana nufin haɗa kayan aiki da masu kunna wuta (alkali metal da alkali metal hydroxides, inorganic salts da wasu acid) a wani rabo, a nutsar da su na wani lokaci, sannan a kammala matakan carbonization da kunnawa a mataki ɗaya.

2. Maganin ruwan sharar gida ta hanyar amfani da foda niƙa na ƙarfe: hanyar sharar gida hanya ce da aka saba amfani da ita don magance ruwan sharar gida na coking. Saboda ƙarancin gurɓataccen foda na cikin gida da kuma ingantaccen aikin sharar gida, wasu masu bincike a China sun gudanar da bincike kan maganin ruwan sharar gida na coking foda. Zhang Jinyong yana amfani da foda na coke da tururi ke kunnawa don sharar gida daga masana'antar coking. Bayan sharar gida, buƙatar iskar oxygen (COD) na ruwan sharar gida ya ragu daga 233mg/L zuwa 50mg/L, wanda ya kai matsayin fitarwa na ƙasa na farko. Liu Xian da abokan aikinsa sun yi amfani da foda na coke don magance sharar gida na coking na biyu, kuma sun yi nazarin yanayin da ya dace don sharar gida na coking foda ta hanyar gwaje-gwaje masu tsauri da tsauri. Sakamakon binciken ya nuna cewa COD na ruwan sharar gida na biochemical bayan an yi amfani da foda na coke na zamani za a iya rage shi zuwa ƙasa da 100mg/L, kuma ƙimar cire chromaticity na iya kaiwa sama da kashi 60%, wanda ya cika buƙatun ingancin ruwa na kamfanonin coking.

3. Samar da foda na niƙa na coke na ƙarfe tare da ƙari: tsarin foda na coke da kansa ba shi da mannewa, kuma yawanci ana amfani da shi ta hanyar ƙara mai ɗaurewa a ciki don matsewa da ƙirƙirarsa. Akwai nau'ikan ƙarin foda na coke da yawa, kuma ingancin coke ɗin da aka samar ba iri ɗaya bane. Liu Baoshan ya yi amfani da sinadarin haɗa humate, ragowar sharar sitaci, slime na kwal, caustic soda da bentonite a matsayin mai ɗaurewa don nazarin adadin ƙarin, yanayin ƙera foda na coke, siffar da girman barbashi na ƙwallon ƙera, da zafin bushewa, kuma an gwada ƙwallon da aka shirya kuma an harba, kuma sakamakon ya nuna cewa ƙwallon foda na coke yana da ƙarfi mai kyau da kwanciyar hankali na zafi, kuma ana iya amfani da shi don samar da iskar gas ta hanyar wucin gadi. Zhang Liqi ya yi amfani da foda na coke da ragowar tar da janareta gas ke samarwa don haɗawa da siffantawa bisa ga wani rabo, sannan a yi oxidized da carbonized don yin coke don gasification. Abubuwan da coke ke da su sun kai matsayin coke na gasification. Yana ba da tushen ka'ida don samar da masana'antu.

4. Foda niƙa coke na ƙarfe don samar da coke na ƙarfe: yawanci ana amfani da foda coke a matsayin sinadari mai rage nauyi a cikin tsarin coking. Ƙara foda coke mai dacewa a cikin tsarin coking na iya inganta ingancin coke. Saboda ƙaruwar ƙarancin albarkatun kwal na coking a China, don faɗaɗa albarkatun kwal na coking da rage farashin haɗa kwal, kamfanonin coking da yawa sun yi ƙoƙarin amfani da foda coke a matsayin ɓangaren haɗa kwal don coking don inganta fa'idodin tattalin arziki na foda coke. Kamfanoni da yawa a China sun gudanar da bincike kan girman barbashi da rabon foda coke. Yang Mingping ya gudanar da gwajin samar da masana'antu bisa ga ƙaramin gwajin tanda na coke. Sakamakon ya nuna cewa a ƙarƙashin yanayin tsarin coking na sama-sama na yau da kullun, yana yiwuwa a ƙara kashi 3% zuwa 5% na foda coke don maye gurbin kwal mai laushi don coking. Matsayin toshe ya ƙaru, kuma ƙimar ciniki ta ƙaru da kusan kashi 3%. Ta hanyar bincike, Wang Dali da abokan aikinsa sun gano cewa coking da foda coke ba shi da wani tasiri a bayyane akan mafi girman hasken vitrinite na kwal ɗin da aka haɗa. Duk da haka, ta hanyar auna ƙananan ƙwayoyin cuta, an gano cewa ƙwayoyin coke da suka fi 0.2mm ba su da alaƙa da juna a cikin coke, kuma yana da wuya a haɗa su da sauran abubuwan haɗin, kuma siffar ba ta canza ba; yayin da ƙananan ƙwayoyin coke da suka fi 0.2mm an naɗe su cikin sauƙi ta hanyar colloid, wanda ya dace da samuwar coke. Mafi kyawun rabon foda coke shine 1.0%-1.7%, mafi kyawun girman ƙwayoyin shine 98%-100% ƙasa da 3mm, 78%-80% ƙasa da 1mm, da kuma 40%-50% ƙasa da 0.2mm.

Niƙa coke na ƙarfe ba za a iya raba shi da niƙa coke na ƙarfe ba. A matsayinta na mai ƙera injin niƙa coke na ƙarfe, HCMalling (Guilin Hongcheng) tana samarwa.coke na ƙarfe Raymondinjin niƙa, coke na ƙarfe mai matuƙar kyauinjin niƙa, coke na ƙarfe a tsayeabin nadiinjin niƙada sauran kayan aiki. Yana iya samar da foda na coke na ƙarfe 80-2500 tare da bayar da tallafin fasaha don amfani da foda na niƙa coke na ƙarfe.
