Kev Tshawb Fawb Txog Lub Cev:
Kev Tawg (Bursting):
- Kev khiav tawm sai ntawm cov khoom volatile: Thaum cov ntsiab lus volatile hauv petroleum coke siab, thaum qhov kub nce siab thaum lub sijhawm pib ntawm calcination, cov khoom volatile khiav tawm sai. Yog tias qhov nrawm khiav tawm sai dhau, lub zog pa loj heev tsim nyob rau hauv cov khoom petroleum coke, ua rau tawg.
- Kev tswj qhov kub tsis zoo: Qhov siab tshaj plaws ntawm cov khoom tawg yooj yim yuav tawm ntawm qhov kub ntawm calcination ntawm 600–700 ° C. Yog tias qhov kub nce sai dhau thaum lub sijhawm no, cov khoom tawg yooj yim yuav tawm mus sai heev, ua rau qhov tshwm sim tawg loj dua.
Cov xwm txheej ntawm kev sib tsoo:
- Kev sib xyaw tsis tiav ntawm cov khoom volatile: Thaum lub sijhawm calcination ntawm cov roj av coke uas muaj zog heev, kev sib xyaw tsis tiav ntawm cov khoom volatile tsim tawm ntau cov pa roj carbon dub thiab cov khoom me me uas tsis tau hlawv.
- Cov tshauv yaj: Cov tshauv hauv cov roj av coke yaj ntawm qhov kub siab thiab sib xyaw nrog cov khoom me me uas tsis tau hlawv kom tsim cov khoom sib xyaw eutectic uas yaj qis uas lo rau ntawm phab ntsa cub lossis cov khoom siv, ua rau muaj kev sib xyaw.
- Kub dhau heev: Thaum qhov kub calcination tshaj qhov kub ntawm cov tshauv, cov tshauv yaj thiab lo rau, tsim cov slag.
Kev Tiv Thaiv:
Kev Tswj Xyuas Kub thiab Kub ntawm Calcination:
- Kev Ua Kub Sib Cais: Thaum lub sijhawm pib ntawm kev hlawv, siv qhov kub qis dua kom cov khoom tawg yooj yim tawm mus qeeb qeeb, zam kev siab ntawm cov pa sab hauv. Piv txwv li, kev ua kub qeeb ua ntej 900 ° C tuaj yeem txhim kho qhov txiaj ntsig tiag tiag.
- Kev tswj qhov kub thiab txias theem siab: Thaum kub siab (piv txwv li, 1240–1300 ° C), txo qhov kub kom tsim nyog los pab txhim kho qhov ceev thiab kev tiv thaiv oxidation ntawm cov coke calcined, txo qhov kev pheej hmoo ntawm slagging.
Kev Txhim Kho ntawm Kev Ua Haujlwm ntawm Cov Khoom Siv Calcination:
- Tswj cov khoom siv qis: Hauv cov cub tawg, tswj cov khoom siv qis kom cov roj av coke ntxiv sai sai tso tawm cov khoom tsis haum, txo nws lub sijhawm nyob hauv lub cub tawg thiab txo qhov yuav muaj slagging.
- Ua kom lub siab tsis zoo nce ntxiv: Tswj lub siab tsis zoo kom yooj yim rau kev tshem tawm cov khoom tsis haum thiab tiv thaiv nws cov khoom sib sau ua ke hauv lub cub tawg.
- Ntxuav cov qhov tawm ntawm cov khoom tsis huv tas li: Ntxuav cov qhov tawm ntawm cov khoom tsis huv thiab cov kav dej kom tsis txhob muaj kev thaiv thiab xyuas kom meej tias cov khoom tsis huv raug tshem tawm yam tsis muaj kev thaiv.
Kev Kho Kom Zoo ntawm Cov Khoom Siv Raw:
- Kev sib xyaw ua ke: Ntxiv cov roj av coke uas tsis tshua muaj zog lossis cov roj av coke uas tau calcined rau hauv cov roj av coke uas muaj zog heev kom txo tau cov roj av uas muaj zog tag nrho. Xyuas kom meej tias muaj cov piv sib npaug thiab sib xyaw kom sib npaug kom tsis txhob muaj cov roj av uas muaj zog heev.
- Tswj cov khoom siv raw me me: Tshem tawm cov khoom loj thiab cov hlau tsis huv kom txo cov ntsiab lus inorganic thiab txo cov qhov chaw slagging.
Kev Txhim Kho Cov Txheej Txheem:
- Kev tswj cov pa oxygen kom zoo: Tswj cov pa oxygen kom zoo kom tsis txhob txo cov huab cua uas ua rau cov tshauv yaj tsawg dua. Piv txwv li, thaum cov pa oxygen qis dua 5%, cov tshauv yaj yuav txo qis 100–150°C, ua rau muaj kev pheej hmoo ntawm kev sib xyaw ua ke.
- Txhim kho qhov kev faib tawm ntawm huab cua: Kho qhov piv ntawm kev faib tawm ntawm huab cua raws li theem calcination kom ntseeg tau tias muaj kev sib xyaw ua ke ntawm cov khoom volatile thiab txo qhov tsim cov pa roj carbon dub thiab cov khoom me me uas tsis tau hlawv.
Kev Hloov Kho thiab Kev Txij Nkawm Khoom Siv:
- Hloov kho cov khoom siv calcination: Rau cov roj av coke uas muaj zog heev, tshwj xeeb yog hloov kho cov qhov cub rotary lossis cov cub tawg, xws li los ntawm kev ntxiv cov channel tso tawm cov khoom tsis muaj zog thiab ua kom zoo dua qhov kev faib tawm ntawm cov huab cua sab hauv, kom hloov kho rau qhov xav tau calcination ntawm cov khoom siv uas muaj zog heev.
- Kev tshuaj xyuas cov khoom siv tsis tu ncua: Xyuas kom cov khoom siv ua haujlwm ib txwm kom tiv thaiv kev kub dhau lossis cua tsis zoo uas tuaj yeem ua rau muaj cov av nplaum. Piv txwv li, tshuaj xyuas cov hlawv thiab cov kav hluav taws thiab ntxuav cov tshauv thiab cov av nplaum uas tau khaws cia sai sai.
