Yiziphi izinto eziyinhloko zokukhiqiza i-graphitized petroleum coke?

Imishini eyinhloko yokukhiqiza i-graphitized petroleum coke yi-continuous graphitization furnace. Izinzuzo zayo zobuchwepheshe kanye nezici zenqubo zenze kwaba ukukhetha okujwayelekile embonini, njengoba kuchazwe ngezansi:

I. Isikhundla Esiyinhloko Sezithando Zokubumba Eziqhubekayo

1. Isimiso Senqubo

Izitofu ze-graphitization eziqhubekayo ziguqula ama-molecule e-carbon ku-petroleum coke kusukela ekuhlelweni okungahlelekile abe yisakhiwo se-lattice esinonxande, esihlelwe ngokulinganayo ngokusebenzisa izinga lokushisa eliphezulu (cishe ama-3000°C) kanye nokwelashwa ngogesi. Le nqubo inika i-petroleum coke amandla kagesi aphezulu kanye nokuqina kokushisa, okwenza kube yinto enhle kakhulu yokwengeza ikhabhoni kanye nezinto zokusetshenziswa zama-electrode e-graphite.

2. Izinzuzo Zokuqhathanisa Imboni

• Isithando Somlilo Sendabuko sase-Acheson: Sidinga ukulayishwa kwenqwaba, ukufudumeza, kanye nokupholisa, okuholela ekusetshenzisweni kwamandla aphezulu kanye nezikhathi zomjikelezo omude (cishe izinsuku ezingu-15-20). Ngaphezu kwalokho, sidinga inani elikhulu lezinto zokuvikela (njenge-coke) zokugcwalisa, okuholela ezindleleni eziphakeme kanye nokusebenza kahle okuphansi.
• Isithando Sokushisa Esiqhubekayo Sokubumba I-Graphitization: Sivumela ukudla okuqhubekayo, ubumba i-graphitization, kanye nokukhipha izinto zokusetshenziswa, ngesithando somlilo esisodwa esikwazi ukukhiqiza amathani angu-50-100 ngosuku. Ukusetshenziswa kwamandla kuncishiswa ngo-30%-50%, futhi akudingeki izinto zokugcwalisa, okunciphisa ukukhiqizwa kwemfucuza.

II. Izici Zobuchwepheshe Zezitofu Zokuhlela Eziqhubekayo

1. Ukusebenza Kahle Kakhulu Nokulondolozwa Kwamandla

Umzimba wesithando usebenzisa isakhiwo sokushisa esinezingqimba eziningi (isb., i-carbon felt, i-graphite felt) ukunciphisa ukulahleka kokushisa, okuphakamisa ukusebenza kahle kokushisa kube ngaphezu kuka-80%. Uhlelo lokushisa olumelana nalo luhlinzeka ngokulawula izinga lokushisa okunembile, okuvimbela ukushisa ngokweqile kwendawo noma ukufudumala okungaphansi kokushisa kanye nokuqinisekisa ikhwalithi ye-graphitization ezinzile.

2. Ukulawula Okuzenzakalelayo

Ifakwe uhlelo lokulawula lwe-PLC, iqapha njalo amapharamitha afana nokushisa, ingcindezi, kanye nogesi, ilungisa ngokuzenzakalelayo amandla okushisa kanye nesivinini sokudla. Amakhono okuqapha kude asekela izexwayiso zamaphutha kanye nokwenza ngcono inqubo, okunciphisa ukungenelela ngesandla.

3. Ukusebenza Kwemvelo

Umklamo wesithando somlilo ovalekile unciphisa uthuli kanye nokukhishwa komoya ophumayo, kuyilapho amayunithi ahlanganisiwe okususa i-sulfurization kanye nokususa uthuli ehlangabezana nezindinganiso zemvelo. Uhlelo lokubuyisa ukushisa okulahliwe lusebenzisa ukushisa komoya ophumayo ukuze lufudumale izinto zokusetshenziswa, okunciphisa ukusetshenziswa kwamandla.

III. Izingxenye Nemisebenzi Yemishini Eyinhloko

1. Isakhiwo Sesithando Somlilo

• Indawo Yokushisa: Yakhiwe ngama-electrode e-graphite noma izintambo zokumelana, inikeza indawo yokushisa ephezulu.
• Isendlalelo Sokufudumeza: Sisebenzisa i-carbon felt noma i-graphite felt ukunciphisa ukulahleka kokushisa.
• Uhlelo Lokudla: Ama-screw conveyor noma ama-feeder adlidlizayo aqinisekisa ukutholakala kwezinto zokusetshenziswa eziqhubekayo nezifanayo.
• Uhlelo Lokukhipha: Amadivayisi apholile ngamanzi noma apholile ngomoya apholisa ngokushesha imikhiqizo ene-graphitized ukuvimbela ukubola.

2. Imishini Esizayo

• Umshini Wokuchoboza Nokuhlola: Uphula i-petroleum coke eluhlaza ibe yizinhlayiya ezingu-1-6mm ukuqinisekisa ukushisa okufanayo.
• Uhlelo Lokususa Uthuli: Izihlungi zezikhwama noma ama-precipitator asebenzisa ugesi aqoqa uthuli futhi ahlanze amagesi okukhipha uthuli.
• Uhlelo Lokulawula: Izinhlelo ze-PLC noma ze-DCS zivumela ukusebenza okuzenzakalelayo ngokugcwele kuyo yonke inqubo.

IV. Amacala Okufaka Isicelo kanye Nezinzuzo Zezomnotho

1. Amaphrojekthi Ajwayelekile Asekhaya

Inkampani yamukele isithando sokushisa esiqhubekayo se-graphitization ukukhiqiza izithasiselo ze-petroleum coke carbon ezifakwe i-graphitized, okwaholela ekukhiqizeni kwansuku zonke kwamathani angu-80 ngesithando sokushisa. Ukusetshenziswa kukagesi ngethani kwehle kusuka ku-6000 kWh ezithandweni zendabuko kuya ku-3500 kWh, okusindisa ama-yuan angaphezu kwezigidi eziyishumi ezindlekweni zikagesi zonyaka. Okuqukethwe kwekhabhoni okuzinzile komkhiqizo kungu-≥98.5%, kanti okuqukethwe kwesulfure kungu-≤0.05%, kufinyelela amazinga athuthukile omhlaba wonke futhi kungena esikhundleni semikhiqizo engenisiwe.

2. Imikhuba Yentuthuko Yamazwe Ngamazwe

Ubuchwepheshe be-graphitization obuqhubekayo busetshenziswa kabanzi eYurophu nase-United States, buhambisana nezinhlelo zokulawula ezihlakaniphile zokukhiqiza ngaphandle komuntu. Izinkampani zaseJapan zithuthukise izakhiwo zesithando somlilo ukulawula ukufana kwezinga lokushisa le-graphitization ngaphakathi kuka-±5°C, okuthuthukisa ukuhambisana komkhiqizo.

V. Izincomo Zokukhetha

1. Ukulinganisa Amandla

Khetha usayizi wesithando somlilo ngokusekelwe ekudingweni kwemakethe: izithando zomlilo ezincane (amathani ayi-10-30 ngosuku) zifanelekela i-R&D noma ukukhiqizwa kwezinga elincane, kuyilapho izithando zomlilo ezinkulu (ezingaphezu kwamathani angama-50 ngosuku) zifanelekela ukukhiqizwa kwezinga lezimboni.

2. Amapharamitha Obuchwepheshe

• Izinga Lokushisa Eliphezulu: ≥3000°C (ukuqinisekisa ukwenziwa kwegrafu okuphelele).
• Ukufana Kwezinga Lokushisa: ≤±10°C (ukuvimbela ukusha ngokweqile kwendawo noma ukusha okungaphansi).
• Ukusetshenziswa Kwamandla: ≤3500 kWh/ton (ngaphansi kwesilinganiso semboni).

3. Ukukhethwa Kwabahlinzeki

Beka phambili abakhiqizi abanerekhodi eliqinisekisiwe kanye nokusekelwa okuqinile ngemuva kokuthengisa, njengezinkampani ezithile zezimboni ezisindayo zasekhaya kanye nemishini. Imishini yabo iphumelele isitifiketi se-ISO futhi ithunyelwe eNingizimu-mpumalanga ye-Asia naseYurophu.
