Ma ke ʻano he mea koʻikoʻi o ka ʻoihana kemika o kēia wā, ʻo ke kaʻina hana calcination kiʻekiʻe o ka petroleum coke he hopena koʻikoʻi i ka maikaʻi a me ka hua o ka petroleum coke. Ma kēia pepa, kūkākūkā ʻia ka ʻenehana calcination kiʻekiʻe o ka petroleum coke i hui pū ʻia me kāna hana nui. No ka hōʻike ʻana i nā ʻoihana.
ʻO ke koʻikoʻi o ka hana ʻana o ka petroleum coke e ka calcination kiʻekiʻe
ʻO ka calcination o ka petroleum coke kekahi o nā kaʻina hana nui i ka hana ʻana o ka anode alumini. ʻO kāna kumu e hoʻoneʻe i nā volatiles mai nā mea maka a hoʻomaikaʻi i ka density, ikaika mechanical, conductivity uila a me ke kūpaʻa kemika o nā mea maka. I ka wā o ke kaʻina calcination, ua loli ke ʻano kumu a me ka hoʻonohonoho hoʻonohonoho ʻana o ka petroleum coke, a ua hoʻomaikaʻi maikaʻi ʻia nā ʻano kino a me nā kemika o nā mea maka ma hope o ka calcination.
Hiki i kēia waiwai huahana kūikawā ke hoʻokō i ka ʻoihana kemika i nā koi hou aʻe, i hoʻohana hou ai kekahi mau ʻoihana ʻoihana. Ma ke kaʻina o ka calcination, ʻo ka ʻoi loa o ka degere calcination a me ka pili o ke kaʻina calcination e hoʻopili i ka hoʻopuka a me ka pololei o ka coke petroleum. No laila, he mea nui ke aʻo ʻana i ka ʻenehana calcination kiʻekiʻe no ka ʻaila coke.
ʻIke loea o ka coke petroleum calcined ma ka wela kiʻekiʻe
ʻO ka hui pū ʻana me ke kālepa kemika o ko mākou ʻāina a hiki i ka calcine i nā koi like ʻole o ka maikaʻi, palekana, ka nui o ka hana ʻana a me nā mea ʻē aʻe o ka huahana coke petroleum, ʻo nā ala calcine wela kiʻekiʻe o kēia manawa o ko mākou ʻāina ʻo: rotary kiln, coke oven, tank furnace. , etc. Hoʻohālikelike ʻia ke kumu, nā hiʻohiʻona, ka hoʻohana ʻana a me nā hōʻailona hoʻokele waiwai o kekahi mau ʻenehana calcination i mea e hāʻawi ai i ka kuhikuhi no ka hana ʻoihana.
(1) Rotary kiln calcining technology
1. Ka loiloi kumu: ʻO ka ʻenehana Rotary kiln i hui pū ʻia me ke ʻano kino kūikawā o ka rotary kiln hiki ke hoʻokō i ka mālama wela maikaʻi o ka coke petroleum paʻa. ʻO ke kumu o ka ʻenehana rotary kiln e hilinaʻi i ka piʻi ʻana o ka wela o waho i ke kaʻina o ka coke petroleum calcination a me ka hana kemika i loko o ka wikiwiki o ka rotation, i mea e hoʻolalelale ai i ka nui o ka puhi ʻana o ka coke petroleum a hana i ka coke petroleum i hana ʻia e ka wela kiʻekiʻe. calcination.
2. Loaʻa ka ʻenehana Rotary kiln i nā kaʻina hana:
1) Hoʻomaʻamaʻa mua: ma ka hoʻohuli lohi ʻana i ka cylinder a hoʻohui i kekahi mau mea puhi ahi e hiki ai i ka coke petroleum o loko ke hiki i ka wahi ignition a puhi mālie;
2) Calcination: ka wikiwiki o waho o ka huli ʻana o ka cylinder, ʻoiai e hoʻonui ana i ka mahana o ka calcination, ua hoʻoikaika ʻia ka hopena kemika coking petroleum i loko;
3) Hoʻoluʻu: ʻO ka condensation o ka petroleum coke ma hope o ka volatilization o ka wai e hana ai i ka petroleum coke me ka pololei kiʻekiʻe.
3, nā pono a me nā pōʻino a me ka loiloi kūpono: hui pū ʻia me ka hana ʻoihana nui, rotary kiln i nā hiʻohiʻona o ka hana maʻalahi, ka huahana nui, ke kumu kūʻai haʻahaʻa, ka mālama kūpono, a me nā mea ʻē aʻe, hiki ke hana pono no nā ʻoihana no 20 a 30 mau makahiki, kūpono no nā ʻano like ʻole o ka hoʻohana ʻana i ka coke petroleum carbon. I ka manawa like, hoʻohana ka rotary kiln ponoʻī i ka rotation and chemical reaction principle o nā mea hoʻopau i loko e mālama i ke kumukūʻai o nā mea puhi. Eia nō naʻe, i ka wā e hoʻololi ai ka coke petroleum i ka axis cylinder, hiki ke maʻalahi ka wela kiʻekiʻe e hoʻopau a hāʻule i ka refractory, e hopena i ka maikaʻi ʻole o nā huahana calcined, a ma waena o ka hana kiʻekiʻe ma kahi o 10% wale nō. .
No laila, i hui pū ʻia me nā hiʻohiʻona o ka rotary kiln, pono nā ʻoihana e hana i ka mālama ʻana i ka mālama ʻana i nā mea kūkulu hale ahi a me nā kaʻina hana i ka wā o ka hana, i mea e hoʻokō ai i nā koi o ka hoʻomaikaʻi ʻana i ka hana hana ʻoihana, hoʻoikaika i ka ikaika calcination a me ka hoʻonui ʻana i ka pololei o ka huahana i ka hiki.
(2) ʻenehana calcination umu Coke
1. Ka loiloi kumu: Coke umu calcination calcines i ka coke i hana kūikawā ma o ka wela wela calcination umu ahi i hana ʻia me nā poloka pōhaku lepo me ke ahi kūpaʻa kiʻekiʻe, a ʻo ka coke i hana ʻia i lepo a mālama ʻia e hana i nā huahana maikaʻi i koi ʻia e ka ʻoihana e hana i ka coke . Ma kēia kaʻina hana, aia nā koi koʻikoʻi i ka hoʻopaʻa ʻana o ka coke maka a me ka mahana a me ka manawa o ka calcination o ka coke.
2, nā pono a me nā pōʻino a me ka nānā pono ʻana: hoʻohālikelike ʻia me ka ʻenehana rotary kiln, ʻoi aku ka kiʻekiʻe o ka hana ʻana o ka umu coke a me nā ʻano kikoʻī kiʻekiʻe. Koho ʻo ia e hana me nā ʻano mea like ʻole, hiki ke hoʻokō i ka mana maʻalahi i ka hoʻohana ʻana, hiki ke hana i kahi kūlana kiʻekiʻe o ka coke i hoʻopau ʻia no nā ʻoihana. I ka manawa like, ʻike pū ʻia ka hana ʻana o ka umu coke me kekahi mau pilikia kūkulu, nā koi kiʻekiʻe o ke kūkulu ʻana i ka umu coke, kiʻekiʻe kiʻekiʻe o ka mālama ʻana i ka wela o ka umu, ʻo ke kumukūʻai mālama kiʻekiʻe e hoʻopilikia i ka helu komo o ka hoʻokomo ʻana i ka umu coke.
Eia nō naʻe, no ka hoʻomohala ʻana i ka ʻenehana coke calcination i ka wā e hiki mai ana, hiki i ka coke umu calcination ke hoʻomaopopo i ke kuleana o ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana o ka hoʻokuʻu ʻana, a hiki ke hana i kekahi mau haʻawina i ka mālama ʻana i ke kaiapuni a me ka hoʻohana piha ʻana i ka ikehu, ʻo ka coke umu calcination he ākea ulu. .
(3) ʻenehana pahu calciner
1. Ka loiloi kumu: ʻO nā hale nui o ka umu calcination canne-type: ʻo ka pahu hānai, ke ala ahi, ke keʻena hoʻololi wela, ka mea hānai a me ka hoʻokuʻu ʻana, ka mea hoʻoheheʻe wai hoʻoluʻu, a me nā mea ʻē aʻe. i ka pahu hoʻomaopopo i ka hopena mau o ka mea kalapona kūloko ma o ka mea paʻa kūloko, i mea e hoʻopau ai i ka calcination wela kiʻekiʻe. Hiki ke hoʻokaʻawale ʻia ka pahu calcination maʻamau i ka calcination downflow a me ka calcination counterflow e like me ke degere a me ke kuhikuhi o ka hoʻokuʻu ʻana i ka uahi.
2, ka maikaʻi a me ka hemahema ka nānā ʻana a me ka nānā pono ʻana: ua hoʻohana nui ʻia ka kapuahi calcination ʻano canner i ko mākou ʻāina, ʻo ia ke ʻano ʻoihana kumu nui o kā mākou ʻoihana kalapona ʻāina, ma o ka hoʻomaʻamaʻa kūikawā o ka petroleum coke hiki ke hoʻokō i ka wela piha, nā koi hoʻomehana indirect, a hiki i ka loko ke pale aku i ka pili ʻana o ka ea, hoʻemi i ka nui o ka nalowale o ka oxygen, hoʻomaikaʻi i ka huahana a me ka maikaʻi o nā huahana i hoʻopau ʻia. Eia nō naʻe, i ka hoʻohana ʻana i ka ʻenehana calciner canister, nui nā kaʻina hana lima, e hoʻonui ai i ka pilikia palekana. I ka manawa like, he nui nā koi o ka pahu calciner ponoʻī, kahi e pilikia ai ka mālama.
I ka wā e hiki mai ana, hiki i nā ʻoihana ke aʻo hou i ka ʻenehana calcination canister mai ka nui o ka hoʻokuʻu ʻana, ka hoʻokolokolo hewa hewa a me nā mea ʻē aʻe, i mea e hoʻokō ai i ke kumu o ka hoʻonui ʻana i ka hana ʻana o ka petroleum coke calcination wela kiʻekiʻe.
I ka hōʻuluʻulu ʻana, ʻo ke kiʻekiʻe kiʻekiʻe o ka petroleum coke calcination he hopena nui i ka ʻoihana kemika a me ka ʻoihana alumini o ko mākou ʻāina. Hiki i nā ʻoihana ke koho i ka ʻenehana calcination kiʻekiʻe kiʻekiʻe e like me kā lākou pono ʻoihana ponoʻī, a ʻike hope i ka hoʻemi ʻana o ke kumukūʻai a me ka hoʻonui ʻana i ka pono o nā ʻoihana.
