Ukuhlaziywa Kokusetshenziswa Kwamandla Okuyinhloko kanye Nemiphumela Yemvelo Ekukhiqizweni Kwe-Graphitized Petroleum Coke
I. Izinqubo Eziyinhloko Zokusetshenziswa Kwamandla
- Ukwelashwa kwe-Graphitization Yokushisa Okuphezulu
Ukuguqulwa kwe-graphitization kuyinqubo eyinhloko, edinga amazinga okushisa afinyelele ku-2,800–3,000°C ukuguqula ikhabhoni engeyona i-graphitic ku-petroleum coke ibe yisakhiwo sekristalu se-graphite. Lesi sigaba sidinga amandla amaningi kakhulu, lapho izitofu zendabuko zase-Acheson zidla u-6,000–8,000 kWh ngethani likagesi. Izitofu ezintsha eziqondile eziqhubekayo zinciphisa lokhu kube ngu-3,000–4,000 kWh ngethani, yize izindleko zamandla zisasebenza ku-50%–60% wezindleko zokukhiqiza eziphelele. - Imijikelezo Emide Yokushisa Nokupholisa
Izinqubo zendabuko zithatha izinsuku ezingu-5-7 ngeqoqo ngalinye, kuyilapho izithando ezintsha zifinyeza lokhu kube amahora angu-24-48. Kodwa-ke, ukupholisa kusadinga amahora angu-480 okupholisa umoya othulile ngokwemvelo. Ukuqala kwezithando njalo kanye nokuvala kuholela ekuchithekeni kwamandla okushisa, okwandisa ukusetshenziswa kwamandla. - Ukusetshenziswa Kwamandla Ezinqubweni Ezisizayo
- Ukuchoboza Nokugaya: I-petroleum coke kumele ichotshozwe ibe yizinhlayiya ezincane ezingama-10-20 mm, bese ukugaya kudla amandla kagesi amaningi.
- Ukuhlanzwa (Ukuwasha nge-Acid): Ama-reagent amakhemikhali asetshenziswa ukususa ukungcola, okwengeza ubunzima benqubo ngaphandle kokusetshenziswa kukagesi ngqo.
- Ukuvikelwa Kwegesi: Amagesi angasebenzi njenge-argon noma i-nitrogen ahlinzekwa njalo ukuvimbela ukungcoliswa, okudinga ukusebenza okuqhubekayo kwemishini yokuhlinzeka ngegesi.
II. Ukuhlaziywa Komthelela Wezemvelo
- Ukukhishwa Kwegesi Engcolile
- Isigaba Sokushisa Okuphansi (Izinga Lokushisa Legumbi–1,200°C): I-calcium oxide (i-CaO) ezintweni zokugcwalisa (i-calcined petroleum coke) isabela ne-carbon ukuze ikhiqize i-carbon monoxide (CO2), kuyilapho ukubola kokushisa kukhiqiza i-methane (CH₄) kanye nokunye ukukhishwa kwe-hydrocarbon.
- Isigaba Sokushisa Okuphezulu (1,200–2,800°C): I-sulfur, umlotha, kanye nezinto eziguquguqukayo ziyabola, zikhiqize izinto ezincane kanye ne-sulfur dioxide (SO₂). Ngaphandle kokwelashwa okuphumelelayo, ukukhishwa kwe-SO₂ kunegalelo emvuleni ene-asidi, kuyilapho izinto ezincane zonakalisa ikhwalithi yomoya.
- Izinyathelo Zokunciphisa Umonakalo: Inhlanganisela yezihlukanisi zeziphepho, izihlanzi ze-alkaline ezinezigaba ezintathu, kanye nezihlungi ze-baghouse kuqinisekisa ukuthi ukukhishwa okulungisiwe kuyahlangabezana nezindinganiso zomthetho.
- Amanzi Angcolile kanye Nemfucuza Eqinile
- Amanzi Angcolile: Ukugeza nge-asidi kukhiqiza amanzi angcolile ane-asidi adinga ukuncishiswa, kuyilapho amanzi okupholisa imishini equkethe izinto ezingcolisa uwoyela ezidinga ukuhlukaniswa nokubuyiselwa.
- Imfucuza Eqinile: Izinto zokugcwalisa ezivivinyiwe ezinokumelana okuphansi ziyafakwa emasakeni ukuze zithengiswe noma zilahlwe endaweni yokulahla imfucuza, okubeka engcupheni yokungcoliswa kwenhlabathi uma zingaphathwanga kahle.
- Ukungcola Kothuli
Uthuli luyakhiqizwa ngesikhathi sokuchoboza, ukuhlunga, kanye nokuhlanza isitofu. Ngaphandle kwezinhlelo zokuqoqa ezivalekile, kubeka impilo yabasebenzi engcupheni futhi kungcolise imvelo.
Izindlela Zokulawula: Uthuli lubanjwa kusetshenziswa ama-suction crane, ama-hood, kanye nezihlungi ze-baghouse ngaphambi kokuba lukhishwe ngezinqwaba zokukhipha umoya. - Ukusetshenziswa Kwemithombo kanye Nokukhishwa Kwekhabhoni
- Imithombo Yamanzi: Amanzi amaningi asetshenziselwa ukupholisa nokuhlanza, okwenza kube nzima kakhulu ukucindezeleka kwamanzi ezindaweni ezomile.
- Isakhiwo Samandla: Ukuthembela kugesi osuselwa kuphethiloli wezinto zasendulo kuholela ekukhishweni kwe-CO₂. Isibonelo, ukukhiqiza ithani elilodwa lama-electrode e-graphite kudla amathani ayi-1.17 amalahle ajwayelekile, okwandisa ngokungaqondile izinyathelo zekhabhoni.
III. Amasu Okuphendula Embonini
- Ukuthuthukiswa Kobuchwepheshe
- Khuthaza izitofu ezintsha eziqondile eziqhubekayo ukuze kufinyezwe imijikelezo futhi kuncishiswe ukusetshenziswa kwamandla (ukusetshenziswa kukagesi kwehla kufinyelele ku-3,500 kWh ngethani).
- Sebenzisa ubuchwepheshe be-microwave graphitization ukuze ufudumale ngokushesha okukhulu (
- Ukuphathwa Kwemvelo
- Ukwelashwa kwegesi elahliwe: Ukukhishwa komlilo emazingeni okushisa aphansi bese usebenzisa iqoqo elihlanganisiwe elihlanzwa ngezigaba eziningi emazingeni okushisa aphezulu.
- Ukuvuselela Amanzi Angcolile: Sebenzisa izinhlelo zokusebenzisa amanzi kabusha ukuze unciphise ukungenisa amanzi ahlanzekile.
- Ukuqinisekisa Udoti Oqinile: Sebenzisa kabusha izinto zokugcwalisa ezingaphansi kwezinga elifanele njengezitsha zokuvuselela izitshalo zensimbi.
- Inqubomgomo kanye Nokubambisana Kwezimboni
- Landela imithetho efana ne-Umthetho Wokuvimbela Nokulawula Ukungcoliswa KomoyafuthiUmthetho Wokuvimbela Nokulawula Ukungcoliswa Kwamanziukuphoqelela izindinganiso eziqinile zokukhishwa kwegesi.
- Thuthukisa amaphrojekthi ezinto ezihlanganisiwe ze-anode ngokwakha amandla okusebenzisa i-graphitization yangaphakathi ukuze unciphise ukuthembela kubahlinzeki bangaphandle futhi unciphise ukungcola okuhlobene nokuhamba.
IV. Isiphetho
Ukukhiqizwa kwe-graphitized petroleum coke kuyinqubo edinga amandla amaningi futhi engcolisayo, lapho ukusetshenziswa kwamandla kugxile ekusetshenzisweni kwe-graphitization yokushisa okuphezulu kanye nomthelela wezemvelo ohlanganisa igesi engcolile, amanzi, imfucuza eqinile, kanye nokungcola kothuli. Imboni inciphisa le miphumela ngentuthuko yezobuchwepheshe (isb., izitofu eziqhubekayo, ukushisa nge-microwave), ukuphathwa kwemvelo (ukuhlanzwa kwezigaba eziningi, ukuvuselelwa kwezinsiza), kanye nokuhambisana kwenqubomgomo (izindinganiso zokukhishwa komoya, ukukhiqizwa okuhlanganisiwe). Kodwa-ke, ukwenziwa ngcono okuqhubekayo kwezakhiwo zamandla—njengokuhlanganisa ugesi ovuselelekayo—kusabalulekile ekufinyeleleni intuthuko esimeme.
