Budada kookaha waa badeeco la soo saaray habka karinta.Sababtoo ah qaybaheeda ayaa aad u yaryar, marka ay ku ururto foornada qaraxa, socodka hawadu ma noqon doono mid siman, taas oo saameyn doonta socodka caadiga ah ee tiirarka walxaha ee foornada qaraxa, mana buuxin karto shuruudaha kookaha birta ah.Sababtoo ah budada kookaha waxay leedahay sifooyinka kaarboonka sarreeya, horumarinta faaruqinta gudaha, iyo xoog gaar ah, cilmi-baarayaasha sayniska ee Shiinaha ayaa sameeyay cilmi-baaris ballaaran oo qoto dheer oo ku saabsan sida loo isticmaalo budada kookaha sannadihii la soo dhaafay.HCMilling (Guilin Hongcheng) waa soo saarahakookaha macdantashiidid.Kuwa soo socdaa waa horudhac ku saabsan isticmaalka warshada wax lagu shiidi karo ee coke metallurgical:

1. Kaarboon firfircoon oo laga helay budada kookaha ee macdanaha ah: Kaarboon firfircooni waa walxo kaarboon ah oo leh qaab dhismeed yar yar oo horumarsan iyo awood adsorption oo xooggan.Waxaa si weyn looga isticmaalaa dhinacyo kala duwan sida warshadaha kiimikada, diyaarinta cuntada, ilaalinta ciidamada iyo warshadaha ilaalinta deegaanka.Waxqabadka kaarboonka firfircoon wuxuu la xiriiraa aagga dusha sare ee gaarka ah, mugga micropore, qaybinta cabbirka daloolka iyo halabuurka kiimikada.Waqtigan xaadirka ah, alaabta ugu muhiimsan ee diyaarinta warshadaha ee kaarboonka firfircoon ee waddankeyga waa alwaax iyo dhuxul.Sanadihii la soo dhaafay, iyadoo ay ugu wacan tahay yaraanta sii kordhaysa ee tamarta iyo xoogga dalka uu saaray ilaalinta deegaanka, dadku waxay si joogto ah u raadinayaan qalab kale oo cayriin ah oo loogu talagalay diyaarinta kaarboonka firfircoon.Budada kookaha waa wax ka soo baxay warshadaha coking.Waxa ay leedahay kaarboonka kaarboonka ee go'an oo sarreeya, ka kooban dambas oo hooseeya, xoog badan, iyo helitaan sahlan oo alaabta ceeriin ah.Waa qalab aad u fiican oo loogu talagalay diyaarinta kaarboon firfircoon.Waqtigan xaadirka ah, kaarboonka firfircoon ayaa inta badan la soo saaraa iyadoo lagu daweynayo budada kookaha iyadoo la adeegsanayo firfircoonida jirka iyo firfircoonida kiimikada.Habka firfircoonida jireed wuxuu u baahan yahay in alaabta ceyriinka ah ay noqdaan kaarboonays ka hor inta aan la kicin, ka dibna la dhaqaajiyo 600 ilaa 1200 ° C.Dhaqdhaqaaqa waxaa ka mid ah gaasaska oxidizing sida CO2 iyo uumiga biyaha, iyo atamka kaarboonka ee walxaha carbon oksaydhka ee gaaska ayaa loo isticmaalaa in lagu dhex maro.Kaarboon firfircoon oo leh daloolo si fiican u horumarsan ayaa lagu sameeyay shaqooyinka furitaanka, ballaarinta iyo abuurista meelo cusub.Dhaqdhaqaaqa kiimikaad waxaa loola jeedaa isku dhafka alaabta ceeriin iyo firfircoonayaasha (birta alkali iyo birta alkali hydroxides, cusbada aan noolaha lahayn iyo asiidhyada qaarkood) qayb gaar ah, iyaga oo dhex gelinaya wakhti go'an, ka dibna dhamaystiraya kaarboonaynta iyo hawlgelinta tallaabooyinka hal tallaabo.

2. Daaweynta biyaha wasakhda ah ee kiimikaad ee biraha kookaha lagu shiido budada: Habka adsorption waa habka caadiga ah ee loo isticmaalo daawaynta coking biyaha wasakhda ah.Iyadoo ay ugu wacan tahay humaagga gudaha ee la sameeyay ee budada kookaha iyo waxqabadka xayeysiinta wanaagsan, cilmi-baarayaasha Shiinaha qaarkood ayaa sameeyay cilmi-baaris ku saabsan daaweynta budada kookaha ee cokeynta biyaha wasakhda ah.Zhang Jinyong waxa uu isticmaalaa budada kookaha ee uumi ka shaqaysiiyo si uu u soo saaro biyaha wasakhda ah ee kimikalka ee warshadda coking.Ka dib xayeysiinta, baahida oksijiinta kiimikaad (COD) ee biyaha wasakhda ah ayaa laga soo yareeyay 233mg/L ilaa 50mg/L, taasoo gaareysa heerka heerka koowaad ee dheecaanka qaranka.Liu Xian iyo al.loo isticmaalo budada kookaha ee daaweynta adsorption sare ee coking biyaha wasakhda ah, oo bartay shuruudaha habraaca ku habboon ee xayeysiiska budada kookaha ee qashinka qashinka ah ee isku-dhafka ah ee tijaabooyinka joogtada ah iyo kuwa firfircoon.Natiijooyinka cilmi-baaristu waxay muujinayaan in COD ee biyaha wasakhda ah ee biochemical ka dib daaweynta budada kookaha ee horumarsan lagu yarayn karo wax ka yar 100mg/L, iyo heerka ka saarista chromaticity wuxuu gaari karaa in ka badan 60%, kaas oo buuxinaya shuruudaha tayada biyaha ee shirkadaha coking.

3. Samaynta budada kookaha ee birta ah oo lagu shiido waxyaabaha lagu daro: habka budada kookaha lafteedu ma laha dhego, waxaana badanaa loo isticmaalaa iyada oo lagu daro binder si loo cadaadiyo oo loo sameeyo.Waxaa jira noocyo badan oo lagu daro budada kookaha, tayada kookaha la soo saarayna isku mid maaha.Liu Baoshan waxa uu isticmaalay wakiilka isku dhafka ah ee humate, haraaga wasakhda istaarijka, dhuxusha dhuxusha, soodhaha caustic iyo bentonite sida xidhaha si uu u barto qadarka wax lagu daro, xaaladaha qaabaynta ee budada kookaha, qaabka iyo xajmiga walxaha kubbadda wax lagu dhejiyo, iyo qalajinta heerkulka, iyo Kubadaha la diyaariyey ayaa la tijaabiyey oo la tuuray, natiijadu waxay muujisay in kubbadaha kookaha ay leeyihiin awood wanaagsan iyo xasilloonida kulaylka, oo loo isticmaali karo in lagu dhaliyo gaas si macmal ah.Zhang Liqi waxa uu isticmaalay budada kookaha iyo hadhaaga daamurka ee uu soo saaray gaaska dhaliyaha si uu isugu qaso oo uu u qaabeeyo iyada oo loo eegayo qayb go'an, ka dibna oksaydhid iyo kaarbooned si uu u sameeyo kookaha gaaska.Qalabka kookaha ayaa gaaray heerka kookaha gaaska.Waxay bixisaa aasaaska aragtida wax soo saarka warshadaha.

4. budada shiididda biraha si ay u soo saarto kookaha birta ah: budada kookaha waxaa badanaa loo isticmaalaa sidii walax khafiifinaysa habka kookaynta.Ku darista budada kookaha ee ku habboon habka kariimka waxay hagaajin kartaa tayada kookaha.Sababo la xiriira yaraanta sii kordheysa ee kheyraadka dhuxusha ee Shiinaha, si loo ballaariyo coking kheyraadka dhuxusha loona yareeyo qiimaha isku dhafka dhuxusha, shirkado badan oo wax lagu karsado ayaa isku dayay in ay u isticmaalaan budada kookaha sida qayb isku dhafka dhuxusha si loo hagaajiyo faa'iidooyinka dhaqaale ee kookaha. budo.Shirkado badan oo Shiinaha ah ayaa sameeyay cilmi baaris ku saabsan xajmiga walxaha iyo saamiga budada kookaha.Yang Mingping waxa uu sameeyay tijaabo wax soo saar warshadeed oo ku salaysan tijaabada foornada kookaha ee yar.Natiijooyinku waxay muujinayaan in marka la eego xaaladaha habka kookaynta sare ee caadiga ah, ay suurtogal tahay in lagu daro 3% ilaa 5% budada kookaha si loogu beddelo dhuxusha caatada ah ee coking.Darajada xannibaadda ayaa kor u kacday, iyo heerka wax kala iibsiga ayaa kordhay ilaa 3%.Iyadoo loo marayo cilmi-baaris, Wang Dali et al.Waxaa la ogaaday in isku-dubbarididda budada kookaha aysan wax saameyn ah ku yeelanaynin milicsiga ugu sarreeya ee vitrinite ee dhuxusha isku dhafan.Si kastaba ha noqotee, iyada oo loo marayo cabbirka microscopic, waxaa la ogaaday in qaybaha budada kookaha ee ka weyn 0.2mm ay madaxbannaan yihiin kookaha, wayna adagtahay in la isku daro qaybaha kale, qaabkuna isma beddelin;halka budada kookaha ee ka yar 0.2mm si fudud loogu duudduubay kolloid, taas oo ku habboon samaynta kookaha.Qaybta ugu fiican ee budada kookaha waa 1.0% -1.7%, cabbirka xajmiga ugu fiican waa 98% -100% ka yar 3mm, 78% -80% in ka yar 1mm, iyo 40% -50% in ka yar 0.2mm.

Shiidida kookaha biraha waa mid aan laga sooci karin warshada shiida ee kookaha.Sida soo saaraha warshada shiida ee coke birta ah, HCMilling (Guilin Hongcheng) waxay soo saartaakookaha macdanta Raymondwarshad, kookaha macdanta ultra-gacanwarshad, kookaha macdanta toosanrullaluistemadkawarshadiyo qalab kale.Waxay soo saari kartaa 80-2500 mesh birta kookaha ah budada kookaha waxayna ku siin kartaa taageero farsamo codsiga budada kookaha ee birta ah.

Haddii aad u baahan tahay wax looga baahan yahay warshadda kookaha ee birta ah, fadlan xor u noqo inaad nala soo xidhiidho faahfaahinta qalabka oo na sii macluumaadka soo socda:
