Hoʻolauna i ka petroleum coke
ʻO ka distillation ʻo Petroleum Coke e hoʻokaʻawale i nā aila māmā a me ke kaumaha, hoʻololi ka aila kaumaha i ka huahana hope loa ma o ke kaʻina hana thermal cracking. E haʻi mai ke ʻano, he ʻano like ʻole ke ʻano a me ka nui o ka coke o nā puʻupuʻu ʻeleʻele (a i ʻole nā mea liʻiliʻi) he luster metala; ʻo nā ʻāpana coke he ʻano porous, ʻo nā mea nui he carbon, nona ka ʻoi aku ma mua o 80wt%, ʻo ke koena he hydrogen, oxygen, nitrogen, sulfur a me nā mea metala. ʻO nā waiwai kemika o ka petroleum coke me kona mau waiwai kino a me ke kemika kū hoʻokahi a me nā waiwai mechanical. ʻO ke kalapona non-volatile ʻo ia ka ʻāpana wela o ia iho, nā mea volatile a me nā haumia mineral (sulfur, nā hui metala, wai, lehu, a me nā mea ʻē aʻe), ʻo kēlā mau hōʻailona āpau e hoʻoholo ai i nā waiwai kemika o coke.
Koka nila:Loaʻa i ka nila koka ke ʻano a me ke ʻano o ka fiber, ʻo ka hapa nui i hoʻohana ʻia e like me ke electrode graphite mana kiʻekiʻe i ka hana kila. No ka nila koka, he koi koʻikoʻi kona ʻano maikaʻi i ka nui o ka sulfur, ka nui o ka lehu, ka volatile a me ka nui maoli, no laila he koi kūikawā no ke kiʻi hana a me nā mea maka o ka nila koka.
Koka huʻa:ka hana kemika kiʻekiʻe, ka ʻike haumia haʻahaʻa, hoʻohana nui ʻia i ka ʻoihana alumini a me ka ʻoihana kalapona.
Koke pana a i ʻole koke poepoe:ʻO ke ʻano poepoe o ka cylindrical, ke anawaena o 0.6-30mm, i hana pinepine ʻia e kahi sulfur kiʻekiʻe, ke koena asphalting kiʻekiʻe, hiki ke hoʻohana wale ʻia no ka hana mana, ka sima a me nā wahie ʻoihana ʻē aʻe.
Koka pauka:i hana ʻia ma o ka hana ʻana i ka coking fluidized, he maikaʻi nā ʻāpana (ke anawaena o 0.1-0.4mm), ʻo ke kiʻekiʻe o ka volatile a me ka thermal expansion coefficient ʻaʻole hiki ke hoʻohana pololei ʻia i nā electrodes a me ka ʻoihana kalapona.
Ka hoʻohana ʻana o ka Petroleum Coke
ʻO ke kahua noi nui o ka petroleum coke ma Kina ka ʻoihana alumini electrolytic, e helu ana ma mua o 65% o ka hoʻohana ʻana o ka petroleum coke. A ukali ʻia e ke kalapona, ka silicon ʻoihana a me nā ʻoihana hoʻoheheʻe ʻē aʻe. Hoʻohana nui ʻia ka petroleum coke ma ke ʻano he wahie i ka sima, ka hana mana, ke aniani a me nā ʻoihana ʻē aʻe, e helu ana i kahi hapa liʻiliʻi. I kēia manawa, ua like like ka lako a me ke koi o ka petroleum coke kūloko. Eia naʻe, ma muli o ka lawe ʻana aku i ka nui o ka petroleum coke kiʻekiʻe haʻahaʻa sulfur, ʻaʻole lawa ka nui o ka petroleum coke kūloko, a pono e lawe ʻia mai ka petroleum coke waena a me ke kiʻekiʻe sulfur no ka hoʻohui. Me ke kūkulu ʻana i ka nui o nā ʻāpana coking i nā makahiki i hala iho nei, e hoʻomaikaʻi ʻia a hoʻonui ʻia ka hana o ka petroleum coke kūloko.
①He ʻoihana hoʻohana nui ka ʻoihana aniani i ka ikehu. ʻO ke kumukūʻai o ka wahie ma kahi o 35% ~ 50% o ke kumukūʻai o ke aniani. ʻO ka umu aniani kahi lako me ka hoʻohana nui ʻana i ka ikehu ma ka laina hana aniani. ② Ke hoʻā ʻia ka umu aniani, ʻaʻole hiki ke pani ʻia a hiki i ka hoʻoponopono hou ʻia ʻana o ka umu (3-5 mau makahiki). No laila, pono e hoʻohui mau ʻia ka wahie e hōʻoia i ka mahana o ka umu o nā tausani kekelē i loko o ka umu. No laila, e loaʻa i ka hale hana pulverizing maʻamau nā wili kūʻokoʻa e hōʻoia i ka hana mau. ③ Hoʻohana ʻia ka pauka coke petroleum i ka ʻoihana aniani, a pono ka maikaʻi he 200 mesh D90. ④ ʻO ka nui o ka wai o ka coke maka he 8% - 15%, a pono e hoʻomaloʻo ʻia ma mua o ke komo ʻana i ka wili. ⑤ ʻO ka haʻahaʻa o ka nui o ka makū o ka huahana i hoʻopau ʻia, ʻoi aku ka maikaʻi. Ma keʻano laulā, ʻoi aku ka maikaʻi o ka hopena dehydration o ka ʻōnaehana kaapuni hāmama.

Ka nānā ʻana i nā pono a me nā hemahema o nā wili wili like ʻole:
ʻO Raymond Mill:me ke kumukūʻai hoʻopukapuka haʻahaʻa, ka hana kiʻekiʻe, ka hoʻohana ʻana i ka ikehu haʻahaʻa, nā lako paʻa a me ke kumukūʻai mālama haʻahaʻa, he mea hana kūpono ia no ka pulverization coke petroleum;
Wili kū pololei:ke kumukūʻai hoʻopukapuka kiʻekiʻe, ka hana kiʻekiʻe a me ka hoʻohana ʻana i ka ikehu kiʻekiʻe;
Wili hopena:ke kumukūʻai hoʻopukapuka haʻahaʻa, ka hana haʻahaʻa, ka hoʻohana ʻana i ka ikehu kiʻekiʻe, ka nui o ka hāʻule ʻana o nā lako a me ke kumukūʻai mālama kiʻekiʻe;
Ka nānā ʻana i nā kumu hoʻohālike wili wili
Nā pono o ka wili wili moʻo HC i ka pulverizing coke petroleum:
1. Hale wili Coke ʻaila HC ʻano: kaomi wili kiʻekiʻe a me ka hoʻopuka kiʻekiʻe, ʻo ia hoʻi he 30% kiʻekiʻe ma mua o ka wili pendulum maʻamau. ʻOi aku ka hopena ma mua o 200% kiʻekiʻe ma mua o ka wili hopena.
2. Kiʻekiʻe ka pololei o ka hoʻokaʻawale ʻana: ʻo ka maikaʻi o ka huahana e pono ai he 200 mesh (D90), a inā ʻoi aku ke kiʻekiʻe, e hiki aku i ka 200 mesh (D99).
3. He haʻahaʻa ka walaʻau o ka ʻōnaehana wili, haʻalulu haʻahaʻa a me ka hana palekana kaiapuni kiʻekiʻe.
4. Ka uku mālama haʻahaʻa, ka mālama pono a me ke kumukūʻai hana haʻahaʻa.
5. Wahi a nā koi o ke kaʻina hana, hiki i ka ʻōnaehana wili ke hala i ka ea wela 300 ° C e hoʻomaopopo i ka hana ʻana o ka maloʻo a me ka wili ʻana (ʻo ka hihia o nā mea kūkulu hale ʻo Three Gorges).
Nā Manaʻo: i kēia manawa, ʻoi aku ka nui o ka mākeke o ka wili wili HC1300 a me HC1700 ma mua o 90% ma ke kahua o ka pulverization petroleum coke.
Pae I:Cka holo wikiwiki ʻana o nā mea maka
ʻO ka nuikōka ʻailaua kuʻi ʻia ka mea e ka mea wili i ka fineness hānai (15mm-50mm) hiki ke komo i ka wili wili.
KahuaII: Gka ʻili ʻana
ʻO ka mea i ʻoki ʻiakōka ʻailaHoʻouna ʻia nā mea liʻiliʻi i ka hopper mālama e ka elevator, a laila hoʻouna ʻia i ke keʻena wili o ka wili me ke kaulike a me ka nui e ka mea hānai no ka wili ʻana.

Nā hiʻohiʻona noi o ka hana ʻana i ka pauka coke petroleum
Kumu hoʻohālike a me ka helu o kēia lako: 3 mau laina hana HC2000
Ke hana ʻana i nā mea maka: pellet coke a me ka huahuakai coke
Ka maikaʻi o ka huahana i hoʻopau ʻia: 200 mesh D95
Ka mana: 14-20t / h
Ua nānā pinepine ka mea nona ka papahana i ke koho ʻana o nā lako o ka wili wili coke petroleum. Ma o ka hoʻohālikelike piha ʻana me nā mea hana mīkini wili he nui, ua kūʻai pinepine lākou i nā seti he nui o nā mīkini wili Guilin Hongcheng HC1700 a me nā lako mīkini wili HC2000, a ua launa pū me Guilin Hongcheng no nā makahiki he nui. I nā makahiki i hala iho nei, ua kūkulu ʻia nā laina hana aniani hou he nui. Ua hoʻouna ʻo Guilin Hongcheng i nā ʻenekinia i ka pūnaewele o ka mea kūʻai aku no nā manawa he nui e like me nā pono o ka mea nona. Ua hoʻohana ʻia nā lako wili wili Guilin Hongcheng i nā papahana pulverizing coke petroleum o ka hale hana aniani i nā makahiki ʻekolu i hala iho nei. ʻO ka laina hana pulverizing coke petroleum i hoʻolālā ʻia e Guilin Hongcheng he hana paʻa, hana kiʻekiʻe, hoʻohana ikehu haʻahaʻa a emi ka haumia o ka lepo i ka hale hana pulverizing, kahi i mahalo nui ʻia e nā mea kūʻai aku.
