Chiyambi cha petroleum coke
Mafuta a coke ndi distillation kuti alekanitse mafuta opepuka ndi olemera, mafuta olemera amasandulika kukhala chinthu chomaliza ndi kung'ambika kwamafuta.Ndiuzeni kuchokera ku maonekedwe, coke ndi yosakhazikika mu mawonekedwe ndi kukula kwa zotupa zakuda (kapena particles) ndi zitsulo zonyezimira;tinthu tating'onoting'ono tokhala ndi porous, zinthu zazikuluzikulu ndi kaboni, zomwe zili ndi zoposa 80wt%, zina zonse ndi haidrojeni, okosijeni, nayitrogeni, sulfure ndi zitsulo.Chemical katundu wa petroleum coke ndi wapadera thupi ndi mankhwala katundu ndi makina katundu.Mpweya wosasunthika womwe ndi gawo la kutentha pawokha, zinthu zosasunthika ndi zonyansa zamchere (sulfure, zopangira zitsulo, madzi, phulusa, ndi zina zotero), zizindikiro zonsezi zimatsimikizira kuti coke ndi mankhwala.
Coke ya singano:ali ndi mawonekedwe a singano ndi mawonekedwe a ulusi, ambiri amagwiritsidwa ntchito ngati electrode yamphamvu ya graphite popanga zitsulo.Pakuti singano coke ali okhwima khalidwe chofunika mu sulfure okhutira, phulusa, kosakhazikika ndi kachulukidwe woona etc, kotero kuti pali chofunika wapadera singano coke processing luso ndi zopangira.
Sponge coke:high chemical reactivity, zonyansa zochepa, zomwe zimagwiritsidwa ntchito makamaka m'makampani a aluminiyamu ndi mafakitale a carbon.
Kuwombera coke kapena globular coke:cylindrical ozungulira mawonekedwe, awiri a 0.6-30mm, kawirikawiri opangidwa ndi mkulu-sulfure, mkulu phula zotsalira, izo zingagwiritsidwe ntchito popanga magetsi, simenti ndi mafuta ena mafakitale.
Powder coke:opangidwa kudzera fluidized coking processing, particles ndi zabwino (m'mimba mwake 0.1-0.4mm), mkulu kosakhazikika ndi matenthedwe kukula koyenera zimapangitsa izo sangathe mwachindunji ntchito maelekitirodi ndi carbon makampani.
Kugwiritsa ntchito Petroleum coke
Gawo lalikulu la ntchito ya petroleum coke ku China ndi mafakitale a aluminiyamu a electrolytic, omwe amawerengera zopitilira 65% zamafuta onse amafuta a petroleum coke.Kutsatiridwa ndi carbon, silicon mafakitale ndi mafakitale ena osungunula.Mafuta a coke amagwiritsidwa ntchito ngati mafuta mu simenti, kupanga magetsi, magalasi ndi mafakitale ena, kuwerengera pang'ono.Pakadali pano, kupezeka ndi kufunikira kwa mafuta am'nyumba amafuta ndikofanana.Komabe, chifukwa cha kutumizidwa kunja kwa mafuta ochuluka a sulfure otsika kwambiri a petroleum coke, kuchuluka kwa mafuta a m’nyumba sikukwanira, ndipo coke yapakatikati ndi yokwera ya sulfur petroleum coke iyenera kutumizidwa kunja kuti iwonjezere.Pomanga mayunitsi ambiri ophikira m'zaka zaposachedwa, kutulutsa kwamafuta am'nyumba kudzakhala bwino ndikukulitsidwa.
① Makampani opanga magalasi ndi makampani omwe amagwiritsa ntchito mphamvu zambiri.Mtengo wake wamafuta umakhala pafupifupi 35% ~ 50% ya mtengo wagalasi.Glass ng'anjo ndi chida chogwiritsa ntchito mphamvu zambiri pamzere wopanga magalasi.② Pamene ng'anjo yamagalasi yayatsidwa, sichitha kutsekedwa mpaka ng'anjoyo itakonzedwanso (zaka 3-5).Chifukwa chake, mafuta amayenera kuwonjezeredwa mosalekeza kuti ng'anjoyo ikhale ndi kutentha kwa zikwi zikwi za ng'anjo.Chifukwa chake, msonkhano wamba wopukutira udzakhala ndi mphero zoyimilira kuti zitsimikizire kupanga kosalekeza.③ Mafuta a coke ufa amagwiritsidwa ntchito m'makampani agalasi, ndipo fineness iyenera kukhala 200 mesh D90.④ Madzi a coke yaiwisi nthawi zambiri amakhala 8% - 15%, ndipo amafunika kuumitsa asanalowe mumphero.⑤ Kutsika kwa chinyezi cha mankhwala omalizidwa, ndibwino.Nthawi zambiri, kuchepa madzi m'thupi kwa dongosolo lotseguka la dera ndikwabwinoko.
Njira yopita ku petroleum coke pulverization
Gawo lofunikira la petroleum coke akupera
| Grindability factor | Chinyezi choyambirira (%) | Kuthetsa chinyezi (%) |
| ＞100 | ≤6 | ≤3 |
| ＞90 | ≤6 | ≤3 |
| ＞80 | ≤6 | ≤3 |
| ＞70 | ≤6 | ≤3 |
| ＞60 | ≤6 | ≤3 |
| ＜40 | ≤6 | ≤3 |
Ndemanga:
1. The grindable coefficient parameter ya petroleum coke material ndizomwe zimakhudza kutuluka kwa mphero.M'munsi mwa coefficient grindable, m'munsi linanena bungwe;
- Chinyezi choyambirira cha zopangira nthawi zambiri chimakhala 6%.Ngati chinyontho cha zinthu zopangira ndi choposa 6%, chowumitsira kapena mphero zitha kupangidwa ndi mpweya wotentha kuti zichepetse chinyezi, kuti ziwongolere kutulutsa komanso mtundu wazinthu zomalizidwa.
Pulogalamu yosankha makina amafuta a coke powder
| 200mesh D90 | Raymond mphero |

| Vertical Roller Mill | 1250 Vertical Roller Mill ikugwiritsa ntchito ku Xiangfan, ndiyogwiritsa ntchito mphamvu zambiri chifukwa cha mtundu wake wakale komanso osasintha kwa zaka.Chomwe kasitomala amasamala ndi ntchito yodutsa mpweya wotentha. | |
| Impact mphero | Msika wa 80% ku Mianyang, Sichuan ndi Suowei, Shanghai isanafike 2009, ikutha tsopano. |
Kuwunika kwa ubwino ndi kuipa kwa mphero zosiyanasiyana:
Raymond Mill:ndi mtengo wotsika wandalama, kutulutsa kwakukulu, kugwiritsa ntchito mphamvu zochepa, zida zokhazikika komanso mtengo wotsika wokonza, ndi zida zabwino kwambiri zopangira mafuta a petroleum coke pulverization;
Chigayo choima:kukwera mtengo kwa ndalama, kutulutsa kwakukulu komanso kugwiritsa ntchito mphamvu zambiri;
Impact Mill:mtengo wotsika wandalama, kutulutsa kochepa, kugwiritsa ntchito mphamvu zambiri, kulephera kwa zida zapamwamba komanso mtengo wokonza;
Analysis pa mphero zitsanzo
Ubwino wa HC mndandanda akupera mphero mu petroleum coke pulverizing:
1. HC Petroleum Coke mphero kapangidwe: mkulu akupera kuthamanga ndi linanena bungwe mkulu, amene ndi 30% apamwamba kuposa wamba pendulum mphero.Zotulutsa ndizoposa 200% kuposa zomwe zimakhudzidwa ndi mphero.
2. Kulondola kwamagulu apamwamba: kuwongolera kwazinthu nthawi zambiri kumafuna mauna 200 (D90), ndipo ngati ndipamwamba, ifika 200 mesh (D99).
3. Dongosolo la mphero lili ndi phokoso lochepa, kugwedezeka pang'ono komanso chitetezo champhamvu cha chilengedwe.
4. Mlingo wochepa wokonza, kukonza bwino komanso mtengo wotsika wantchito.
5. Malingana ndi zofunikira za ndondomekoyi, makina opangira mphero amatha kudutsa mpweya wotentha wa 300 ° C kuti azindikire kupanga kuyanika ndi kupera (nkhani ya zipangizo zomangira za Three Gorges).
Ndemanga: pakali pano, HC1300 ndi HC1700 mphero akupera ali ndi gawo la msika woposa 90% m'munda wa petroleum coke pulverization.
Gawo I:Ckuthamanga kwa zipangizo
Chachikulupetroleum cokeZinthu zimaphwanyidwa ndi chophwanyira ku chakudya chabwino (15mm-50mm) chomwe chingalowe mu mphero.
GawoII: Gkukwera
Wophwanyidwapetroleum cokezipangizo zing'onozing'ono zimatumizidwa ku hopper yosungirako ndi elevator, ndiyeno zimatumizidwa ku chipinda chopera cha mphero mofanana komanso mochuluka ndi wodyetsa kuti akupera.
Gawo III:Sankhanindi
Zida zogayidwa zimasinthidwa ndi kachitidwe ka grading, ndipo ufa wosayenerera umayikidwa ndi gulu ndikubwerera ku makina akuluakulu kuti agayidwenso.
GawoV: Ckusonkhanitsa zinthu zomalizidwa
Ufa womwe umagwirizana ndi fineness umayenda mupaipi ndi gasi ndikulowa m'malo otolera fumbi kuti alekanitse ndi kusonkhanitsa.Ufa womalizidwa womwe wasonkhanitsidwa umatumizidwa ku silo yomalizidwa ndi chipangizo chotumizira kudzera pa doko lotayira, kenako nkumapakidwa ndi tanker yaufa kapena paki yokha.
Zitsanzo zogwiritsira ntchito mafuta a coke powder processing
Chitsanzo ndi chiwerengero cha zipangizo izi: 3 HC2000 mizere kupanga
Kukonza zopangira: pellet coke ndi siponji coke
Ubwino wa zinthu zomalizidwa: 200 mauna D95
Mphamvu: 14-20t / h
Mwiniwake wa polojekitiyi wakhala akuyendera kambirimbiri makina osankhidwa a mphero yamafuta a coke.Kupyolera mu kuyerekeza ndi ambiri opanga makina mphero, iwo motsatizana anagula seti ambiri Guilin Hongcheng HC1700 makina mphero ndi HC2000 makina mphero zida, ndipo akhala ochezeka ndi mgwirizano ndi Guilin Hongcheng kwa zaka zambiri.M'zaka zaposachedwa, mizere yambiri yopangira magalasi yamangidwa.Guilin Hongcheng watumiza mainjiniya kumalo a kasitomala nthawi zambiri malinga ndi zosowa za eni ake.Guilin Hongcheng zida mphero zakhala zikugwiritsidwa ntchito mu mafuta coke pulverizing mapulojekiti fakitale galasi mu zaka zitatu posachedwapa.The petroleum coke pulverizing kupanga mzere wopangidwa ndi Guilin Hongcheng ali ndi ntchito khola, linanena bungwe mkulu, otsika mphamvu mowa ndi zochepa kuipitsidwa fumbi mu msonkhano pulverizing, amene wakhala kwambiri kutamandidwa ndi makasitomala.
