Introduction to petroleum coke
ʻO ka Petroleum coke ka distillation e hoʻokaʻawale i ka ʻaila māmā a me ke kaumaha, lilo ka ʻaila kaumaha i huahana hopena ma ke kaʻina hana hoʻoheheʻe wela.E haʻi mai ka nānā aku, ʻaʻole i maʻamau ke ʻano o ka coke a me ka nui o nā puʻupuʻu ʻeleʻele (a i ʻole nā particle) he luster metala;ʻO nā ʻāpana coke me ke ʻano porous, ʻo nā mea nui he kalapona, 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 kino kino a me nā waiwai kemika a me nā waiwai mechanical.ʻO ke kalapona non-volatile ʻo ia ka ʻāpana wela nona iho, nā mea maʻemaʻe a me nā mea haumia mineral (sulfur, pūhui metala, wai, lehu, a me nā mea ʻē aʻe).
Needle coke:Loaʻa iā lākou ke ʻano o ka nila a me ke ʻano fiber, ʻo ka hapa nui i hoʻohana ʻia ma ke ʻano he electrode graphite mana kiʻekiʻe i ka hana kila.No ka mea, he koʻikoʻi koʻikoʻi ko ka coke needle i loko o ka sulfur maʻiʻo, ka lehu maʻiʻo, volatile a me ka ʻoiaʻiʻo maoli etc.
Sponge coke:kiʻekiʻe kemika reactivity, haʻahaʻa haumia maʻiʻo, nui i hoʻohana 'ia ma ka aluminika a me ka carbon hana.
Paʻa coke a i ʻole coke puni honua:cylindrical spherical shape, ke anawaena o 0.6-30mm, hana pinepine ia e ka sulfur kiʻekiʻe, ke koena aspalting kiʻekiʻe, hiki ke hoʻohana wale ʻia no ka hana mana, sima a me nā wahie ʻoihana ʻē aʻe.
ʻO ka pauka coke:hana ʻia ma o ka hoʻoheheʻe ʻana o ka coking fluidized, maikaʻi nā ʻāpana (ka anawaena o 0.1-0.4mm), kiʻekiʻe volatile a me ka thermal expansion coefficient ʻaʻole hiki ke hoʻohana pololei ʻia i nā electrodes a me ka ʻoihana kalapona.
Ka hoohana ana i ka Petroleum coke
ʻO ke kahua noi nui o ka petroleum coke ma Kina he ʻoihana alumini electrolytic, ʻoi aku ma mua o 65% o ka nui o ka hoʻohana ʻana i ka coke petroleum.Hahai ʻia e ke kalapona, ka silikoni ʻoihana a me nā ʻoihana hoʻoheheʻe ʻē aʻe.Hoʻohana nui ʻia ka Petroleum coke e like me ka wahie i ka sima, ka mana hana, ke aniani a me nā ʻoihana ʻē aʻe, e helu ana i kahi hapa liʻiliʻi.I kēia manawa, ʻo ka hāʻawi ʻana a me ke koi ʻana o ka coke petroleum home ka mea like.Eia nō naʻe, ma muli o ka lawe ʻia ʻana o ka nui o ka coke ʻaila kiʻekiʻe kiʻekiʻe o ka sulfur haʻahaʻa, ʻaʻole lawa ka nui o ka hoʻolako ʻana o ka ʻaila aila home, a pono e lawe ʻia mai ka coke aila sulfur kiʻekiʻe a kiʻekiʻe.Me ke kūkulu ʻana i ka nui o nā ʻāpana coking i nā makahiki i hala iho nei, e hoʻomaikaʻi a hoʻonui ʻia ka hoʻopuka ʻana o ka coke petroleum home.
① ʻO ka ʻoihana aniani kahi ʻoihana hoʻohana ikehu kiʻekiʻe.ʻO kāna kumukūʻai wahie e pili ana i 35% ~ 50% o ke kumukūʻai aniani.ʻO ka umu aniani kahi mea hana me ka ʻoi aku o ka ikehu ma ka laina hana aniani.② Ke hoʻā ʻia ka umu aniani, ʻaʻole hiki ke pani ʻia a hiki i ka hoʻopau ʻana o ka umu (3-5 mau makahiki).No laila, pono e hoʻohui mau ʻia ka wahie e hōʻoia i ka wela o ka umu o nā kaukani degere i loko o ka umu.No laila, loaʻa i ka hale hana pulverizing maʻamau nā wili e hōʻoia i ka hana mau.③ Hoʻohana ʻia ka pauka coke Petroleum i ka ʻoihana aniani, a ʻo ka fineness e koi ʻia he 200 mesh D90.④ ʻO ka nui o ka wai o ka coke maka he 8% - 15%, a pono e maloʻo ma mua o ke komo ʻana i ka wili.⑤ ʻOi aku ka maikaʻi o ka haʻahaʻa haʻahaʻa o ka makū o ka huahana i hoʻopau ʻia.ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka hopena dehydration o ka ʻōnaehana kaapuni hāmama.
Kaʻina hana o ka petroleum coke pulverization
Ka palena nui o ka wili aila coke
| Mea hiki ke wili | ʻO ka mākū mua（%） | Hoʻopau i ka makū（%） |
| ＞100 | ≤6 | ≤3 |
| ＞90 | ≤6 | ≤3 |
| ＞80 | ≤6 | ≤3 |
| ＞70 | ≤6 | ≤3 |
| ＞60 | ≤6 | ≤3 |
| <40 | ≤6 | ≤3 |
ʻŌlelo:
1. ʻO ka ʻāpana coefficient grindable o ka ʻaila coke ka mea e pili ana i ka hoʻopuka ʻana o ka wili wili.ʻO ka haʻahaʻa o ka coefficient grindable, ʻoi aku ka haʻahaʻa o ka huahana;
- ʻO ka maʻamau mua o nā mea maka he 6%.Inā ʻoi aku ka nui o ka wai o nā mea maka ma mua o 6%, hiki ke hoʻolālā ʻia ka mea maloʻo a wili paha me ka ea wela e hōʻemi ai i ka wai, i mea e hoʻomaikaʻi ai i ka huahana a me ka maikaʻi o nā huahana i hoʻopau ʻia.
ʻO ka papahana koho hoʻohālike mīkini ʻaila coke pauda
| 200 mesh D90 | ʻO Raymond mill |
|
| Milla Roller Vertical | Ke hoʻohana nei ʻo 1250 Vertical Roller Mill ma Xiangfan, ʻoi aku ka nui o ka ikehu ma muli o kona ʻano kahiko a me ka ʻole o ka hoʻonui ʻana no nā makahiki.ʻO ka mea e mālama ai ka mea kūʻai aku ʻo ia ka hana o ka hele ʻana i ka ea wela. | |
| Milla hopena | ʻO ka māhele mākeke o 80% ma Mianyang, Sichuan a me Suowei, Shanghai ma mua o 2009, ke hoʻopau nei i kēia manawa. |
Ka nānā 'ana i nā pono a me nā pō'ino o nā wili wili like 'ole:
Raymond Mill:me ke kumu kūʻai haʻahaʻa haʻahaʻa, nā huahana kiʻekiʻe, ka hoʻohana ʻana i ka ikehu haʻahaʻa, nā mea paʻa paʻa a me ke kumukūʻai mālama haʻahaʻa, he mea pono ia no ka petroleum coke pulverization;
Hale wili pololei:kiʻekiʻe ka hoʻokomo kālā, kiʻekiʻe ka hoʻopuka a me ka nui o ka ikehu;
hale wili hopena:kumu kūʻai haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, kiʻekiʻe ka hoʻohana ʻana i ka ikehu, kiʻekiʻe o ka hemahema o ka lako a me ke kumukūʻai mālama kiʻekiʻe;
Ka nānā 'ana i nā mea wili wili
ʻO nā pono o ka HC series grinding mill i ka petroleum coke pulverizing:
1. HC Petroleum Coke mill hale: kiʻekiʻe wili kaomi a kiʻekiʻe puka, ʻo ia ka 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 papa helu pololei: ka huahana fineness maʻamau koi 200 mesh (D90), a ina e oi aku, e hiki i 200 mesh (D99).
3. He haʻahaʻa ka walaʻau, haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana hoʻomalu kaiapuni kiʻekiʻe.
4. Haʻahaʻa haʻahaʻa mālama, mālama kūpono a me ka uku hana haʻahaʻa.
5. E like me nā koi kaʻina hana, hiki i ka ʻōnaehana wili ke hele i ka ea wela 300 ° C e ʻike ai i ka hana ʻana o ka maloʻo a me ka wili ʻana (ʻo ka hihia o nā mea kūkulu hale ʻekolu Gorges).
Manaʻo: i kēia manawa, ʻo HC1300 a me HC1700 ka mīkini wili i loaʻa i kahi mākeke ma mua o 90% ma ke kahua o ka petroleum coke pulverization.
Ka Papa I:Cka holo ʻana o nā mea maka
ʻO ka nuiʻaila cokeʻO nā mea i'ōwiliʻia e ka mea'ōpala i ka momona hānai (15mm-50mm) hiki ke komo i ka wili wili.
Ke kahuaII: Gʻōniʻoniʻo
ʻO ka ʻehaʻaila cokeHoʻouna ʻia nā mea liʻiliʻi i ka hopper waihona e ka elevator, a laila hoʻouna ʻia i ke keʻena wili o ka wili me ka like a me ka quantitatively e ka mea hānai no ka wili.
Ka Papa III:Hoʻokaʻawaleana
Hoʻomaʻamaʻa ʻia nā mea wili e ka ʻōnaehana grading, a ʻo ka pauka kūpono ʻole e helu ʻia e ka papa helu a hoʻihoʻi ʻia i ka mīkini nui no ka wili hou ʻana.
Ke kahuaV: Cka ʻohi ʻana i nā huahana i hoʻopau ʻia
ʻO ka pauka e like me ka maikaʻi e kahe ana ma ka pipeline me ke kinoea a komo i ka ʻohi lepo no ka hoʻokaʻawale ʻana a me ka hōʻiliʻili.Hoʻouna ʻia ka pauka i hōʻiliʻili ʻia i ka silo huahana i hoʻopau ʻia e ka mea lawe ma o ke awa hoʻokuʻu ʻana, a laila hoʻopili ʻia e ka pahu pahu pauda a i ʻole ka packer ʻakomi.
Nā hiʻohiʻona hoʻohana no ka hoʻoili ʻana i ka pauka coke petroleum
Hoʻohālike a me ka helu o kēia mea hana: 3 HC2000 laina hana
Ka hana ʻana i nā mea maka: pellet coke a me sponge coke
ʻO ka maikaʻi o ka huahana i hoʻopau ʻia: 200 mesh D95
Kaha: 14-20t / h
Ua nānā ka mea nona ka papahana i ke koho ʻana i nā mea hana o ka petroleum coke grinding mill no nā manawa he nui.Ma o ka hoʻohālikelike piha ʻana me nā mea hana mīkini wili he nui, ua kūʻai aku lākou i nā pūʻulu he nui o Guilin Hongcheng HC1700 milling machine a me HC2000 milling machine, 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.Ua hoʻouna ʻo Guilin Hongcheng i nā ʻenekinia i ka pūnaewele o ka mea kūʻai aku no nā manawa he nui e like me ka makemake o ka mea nona.Ua hoʻohana ʻia ʻo Guilin Hongcheng i nā mea wili wili i ka ʻaila coke pulverizing papahana o ka hale 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, hoʻopuka kiʻekiʻe, haʻahaʻa haʻahaʻa a me ka liʻiliʻi o ka lepo lepo i loko o ka hale hana pulverizing, i mahalo nui ʻia e nā mea kūʻai.
