Inqubo ye-graphitization ye-graphitized petroleum coke iyisixhumanisi esijwayelekile sokukhiqiza esidla amandla amaningi, kanye nezici zayo zokusetshenziswa kwamandla kanye nezici ezibalulekile ezithonya ezichazwe kanje:
I. Idatha Yokusetshenziswa Kwamandla Okuyinhloko
1. Igebe Phakathi Kokusetshenziswa Kwamandla Omqondo Nangempela Lapho izinga lokushisa le-graphitization lifinyelela ku-3,000°C, ukusetshenziswa kwamandla omqondo we-ton eyodwa yemikhiqizo ebhakiwe kungu-1,360 kWh. Kodwa-ke, ekukhiqizweni kwangempela, amabhizinisi asekhaya ngokuvamile asebenzisa u-4,000–5,500 kWh ngethani, okuphindwe kathathu kuya kane kunenani lomqondo. Isibonelo, isitshalo esikhulu sekhabhoni esikhiqiza amathani ayi-100,000 ama-electrode e-graphite minyaka yonke sisebenzisa u-3,000–5,000 kWh ngethani ngesikhathi sesigaba se-graphitization, okugqamisa ukucindezela okukhulu kwamandla. 2. Ukulingana Kwezindleko Ekukhiqizweni kwezinto ze-anode ye-graphite yokwenziwa, izindleko ze-graphitization zibiza cishe u-50% wezindleko eziphelele, okwenza kube yindawo ebalulekile yokunciphisa izindleko. Izindleko zikagesi zakha ngaphezu kuka-60% wezindleko eziphelele ze-graphitization, okunquma ngqo ukusebenza kahle kwezomnotho kwenqubo.
II. Ukuhlaziywa Kwezimbangela Zokusetshenziswa Kwamandla Aphezulu
1. Izidingo Zenqubo Eyisisekelo Ukwenziwa kwe-graphit kudinga ukwelashwa kokushisa okuphezulu (2,800–3,000°C) ukuguqula ama-athomu e-carbon kusuka esakhiweni esinezingqimba ezingahlelekile abe yisakhiwo sekristalu se-graphite esihlelekile. Le nqubo idinga ukufakwa kwamandla okuqhubekayo ukuze kunqotshwe ukumelana kwe-interatomic, okuholela ekusetshenzisweni kwamandla okuphezulu ngokwemvelo.
2. Ukusebenza Kahle Kancane Kwezinqubo Zendabuko
- I-Acheson Furnace: Indlela evamile, kodwa esebenza kahle ngokushisa okungu-30% kuphela, okusho ukuthi u-30% kuphela wamandla kagesi asetshenziselwa imikhiqizo ye-graphiting, kuyilapho okusele kuchitheka ngokushabalaliswa kokushisa kwesithando kanye nokusetshenziswa kwezinto zokumelana.
- Imijikelezo Emide Yokuvula Amandla: Ubude bokuvula amandla ngesithando esisodwa busukela emahoreni angu-40-100, kanti imijikelezo yokukhiqiza ihlala izinsuku ezingu-20-30, okwandisa ukusetshenziswa kwamandla. 3. Imishini Nezithiyo Zokusebenza
- Ubuningi bamanje be-furnace core bunqunyelwe amandla okunikezwa kwamandla. Ukwanda kobuningi bamanje kunganciphisa isikhathi sokusebenza kwamandla kodwa kudinga ukuthuthukiswa kwemishini, okwandisa izindleko zokutshalwa kwezimali.
- Amazinga okunyuka kwezinga lokushisa ayavinjelwa ukuvimbela ukuqhekeka komkhiqizo ekucindezelekeni kokushisa, okunciphisa isikhala sokwenza ngcono ukunciphisa ukusetshenziswa kwamandla.
III. Intuthuko kanye nemiphumela yobuchwepheshe bokonga amandla
1. Ukusetshenziswa Kwezinhlobo Zesithando Esisha
- Isithando Sokushisa Esingaphakathi Sochungechunge Lwe-Graphitization: Isimiso: Sishisa ngqo ama-electrode ngaphandle kwezinto zokumelana, sinciphisa ukulahleka kokushisa. Umphumela: Sinciphisa ukusetshenziswa kwamandla ngo-20%–35% futhi sifinyeza isikhathi sokushisa sibe amahora angu-7–16.
- I-Furnace Yohlobo Lwebhokisi: Isimiso: Ihlukanisa umongo wesithando sibe amakamelo amaningi, ngezinto ze-anode ezifakwa emabhokisini ahambisana ne-graphite aqhubayo azifudumezayo uma esetshenziswa. Umphumela: Wandisa amandla asebenzayo esithando esisodwa, ukhuphula ukusetshenziswa kwamandla okuphelele ngo-~10% kuphela, wehlisa ukusetshenziswa kwamandla eyunithi ngo-40%–50%, futhi uqeda izindleko zezinto zokumelana.
- Isithando Somlilo Esiqhubekayo: Isimiso: Sivumela ukukhiqizwa okuqhubekayo okuhlanganisiwe (ukulayisha, ukukhanyisa, ukupholisa, ukulayisha), ukugwema ukulahlekelwa ukushisa ngenxa yokusebenza kwesithando somlilo ngezikhathi ezithile. Umphumela: Kunciphisa ukusetshenziswa kwamandla ngo-~60%, kufinyeza kakhulu imijikelezo yokukhiqiza, futhi kuthuthukisa ukuzenzekela. 2. Izinyathelo Zokwenza Inqubo Isebenze Kahle
- Izakhiwo zokuvikela isithando somlilo ezithuthukisiwe ukuze kuncishiswe ukulahleka kokushisa nokuthuthukisa ukusebenza kahle kokushisa.
- Ukuthuthukiswa kwemiklamo yensimu yokushisa esebenza kahle yokusatshalaliswa kwezinga lokushisa elifanayo kanye nokusetshenziswa kwamandla okuncishisiwe.
- Izinhlelo zokulawula izinga lokushisa ezihlakaniphile eziqukethe ukuqapha kwezindawo eziningi kanye nama-algorithms ahlakaniphile okuphathwa kwejika lokushisa okunembile, ukuvimbela ukumoshwa kwamandla.
IV. Imikhuba Nezinselele Zemboni
1. Ukufuduka Komthamo Umthamo wokufaka i-graphitization ugxile enyakatho-ntshonalanga yeShayina, usebenzisa amanani kagesi aphansi ukuze kuncishiswe izindleko. Isibonelo, i-Inner Mongolia ihlanganisa u-47% wamandla kazwelonke wokufaka i-graphitization, iba yisikhungo sokukhiqiza esiyinhloko. 2. Ukuthuthukiswa Kwezobuchwepheshe Okuqhutshwa Yinqubomgomo Ngaphansi kwezinqubomgomo zokusetshenziswa kwamandla "okulawula okubili", amandla okufaka i-graphitization anamandla aphezulu abhekene nemikhawulo, okuphoqa amabhizinisi ukuthi amukele izinqubo zokonga amandla. Izinkampani ezinamakhono okukhiqiza ahlanganisiwe (isb., ukuzihlinzeka nge-graphitization) zithola izinzuzo zokuncintisana, zisheshisa ukuhlanganiswa kwemakethe kubadlali abaphambili. 3. Ingozi Yokufakwa Kwezobuchwepheshe Ngenkathi izitofu eziqhubekayo kanye nezinye ubuchwepheshe obusha zinikeza ukonga okukhulu kwamandla, izindleko zazo zemishini ephezulu kanye nezithiyo zobuchwepheshe zivimbela ukushintshwa okusheshayo kwezitofu zendabuko zase-Acheson. Amabhizinisi kumele alinganisele ukutshalwa kwezimali kobuchwepheshe ngokumelene nezinzuzo zesikhathi eside.
