Chiyambi cha petroleum coke
Mafuta a petroleum coke ndi distillation yolekanitsa mafuta opepuka ndi olemera, mafuta olemera amasanduka chinthu chomaliza pogwiritsa ntchito njira yotenthetsera. Onani kuchokera ku mawonekedwe ake, mafuta a petroleum ndi osakhazikika mu mawonekedwe ndi kukula kwa ziphuphu zakuda (kapena tinthu tating'onoting'ono) kukhala kunyezimira kwachitsulo; tinthu ta petroleum coke tili ndi kapangidwe ka mapokoso, zinthu zazikulu ndi kaboni, zomwe zili ndi zoposa 80wt%, zina zonse ndi hydrogen, oxygen, nayitrogeni, sulfure ndi zinthu zachitsulo. Makhalidwe a mankhwala a petroleum coke ndi mawonekedwe ake apadera a thupi ndi mankhwala komanso mawonekedwe a makina. Mpweya wosasinthasintha womwe ndi gawo la kutentha lokha, zinthu zosasunthika komanso zodetsa mchere (sulfure, zinthu zachitsulo, madzi, phulusa, ndi zina zotero), zizindikiro zonsezi zimatsimikizira mawonekedwe a mankhwala a petroleum coke.
Singano ya coke:Ili ndi kapangidwe ka singano ndi kapangidwe ka ulusi, ndipo ambiri amagwiritsidwa ntchito ngati ma electrode amphamvu kwambiri a graphite popanga zitsulo. Pa needle coke, ili ndi sulfure yambiri, phulusa losakhazikika, kusinthasintha kwa nthaka komanso kukhuthala kwenikweni, kotero kuti pali zofunikira zapadera pakupanga zinthu za singano ndi zopangira.
Koka wa siponji:mankhwala ambiri, kuchuluka kochepa kwa zinthu zodetsedwa, zomwe zimagwiritsidwa ntchito makamaka m'makampani opanga aluminiyamu ndi kaboni.
Coke yojambulidwa kapena coke yozungulira:Chozungulira chozungulira, m'mimba mwake wa 0.6-30mm, nthawi zambiri chimapangidwa ndi zotsalira za sulfure wambiri, chingagwiritsidwe ntchito popanga magetsi, simenti ndi mafuta ena amafakitale.
Koka wa ufa:Popeza zimapangidwa kudzera mu kukonza madzi, tinthu tating'onoting'ono ndi tating'onoting'ono (m'mimba mwake ndi 0.1-0.4mm), kuchuluka kwa kutentha komanso kutentha kumapangitsa kuti tisagwiritsidwe ntchito mwachindunji mu ma electrode ndi makampani opanga kaboni.
Kugwiritsa ntchito Petroleum coke
Gawo lalikulu lomwe limagwiritsidwa ntchito kwambiri pa petroleum coke ku China ndi mafakitale a aluminiyamu, omwe amawerengera oposa 65% ya mafuta onse a petroleum coke. Kutsatiridwa ndi carbon, silicon yamafakitale ndi mafakitale ena osungunulira. Petroleum coke imagwiritsidwa ntchito kwambiri ngati mafuta mu simenti, kupanga magetsi, magalasi ndi mafakitale ena, zomwe zimapangitsa kuti pakhale gawo laling'ono. Pakadali pano, kupezeka ndi kufunikira kwa petroleum coke yapakhomo ndikofanana. Komabe, chifukwa cha kutumiza kunja kwa petroleum coke yambiri ya sulfure, mafuta onse a petroleum coke apakhomo ndi osakwanira, ndipo petroleum coke yapakati ndi yayikulu ya sulfure iyenera kutumizidwa kunja kuti iwonjezere. Ndi kumangidwa kwa mayunitsi ambiri ophikira m'zaka zaposachedwa, kutulutsa kwa petroleum coke yapakhomo kudzawongoleredwa ndikukulitsidwa.
①Makampani opanga magalasi ndi makampani omwe amagwiritsa ntchito mphamvu zambiri. Mtengo wake wamafuta ndi pafupifupi 35% ~ 50% ya mtengo wagalasi. Chitofu chagalasi ndi chipangizo chomwe chimagwiritsa ntchito mphamvu zambiri mu mzere wopanga magalasi. ② Chitofu chagalasi chikayatsidwa, sichingatsekedwe mpaka ng'anjoyo itakonzedwanso (zaka 3-5). Chifukwa chake, mafuta ayenera kuwonjezeredwa nthawi zonse kuti atsimikizire kutentha kwa ng'anjo kukhala madigiri zikwizikwi mu ng'anjo. Chifukwa chake, malo ogwirira ntchito opukutira mafuta azikhala ndi ma mphero okhazikika kuti atsimikizire kupanga kosalekeza. ③ Ufa wa coke wa petroleum umagwiritsidwa ntchito mumakampani opanga magalasi, ndipo kusalala kwake kumafunika kukhala 200 mesh D90. ④ Madzi a coke yaiwisi nthawi zambiri amakhala 8% - 15%, ndipo amafunika kuumitsidwa asanalowe mu mphero. ⑤ Chinyezi cha chinthu chomalizidwa chikachepa, chimakhala bwino. Nthawi zambiri, mphamvu ya madzi m'dongosolo lotseguka imakhala yabwinoko.
Kuyenda kwa njira yopangira mafuta a coke
Gawo lofunika kwambiri la kupukusira mafuta a coke
| Chinthu chophwanyira | Chinyezi chachikulu (%) | Mapeto a chinyezi (%) |
| ＞100 | ≤6 | ≤3 |
| ＞90 | ≤6 | ≤3 |
| ＞80 | ≤6 | ≤3 |
| ＞70 | ≤6 | ≤3 |
| ＞60 | ≤6 | ≤3 |
| 40 | ≤6 | ≤3 |
Ndemanga:
1. Gawo la coefficient yophwanyika ya petroleum coke ndi chinthu chomwe chimakhudza kutulutsa kwa mphero yophwanyika. Coefficient yophwanyika ikatsika, kutulutsa kwake kumachepa;
- Chinyezi choyamba cha zipangizo zopangira nthawi zambiri chimakhala 6%. Ngati chinyezi cha zipangizo zopangira chili choposa 6%, choumitsira kapena mphero chingapangidwe ndi mpweya wotentha kuti chichepetse chinyezi, kuti chiwongolere kutulutsa ndi ubwino wa zinthu zomalizidwa.

Kusanthula ubwino ndi kuipa kwa mphero zosiyanasiyana zopukusira:
Raymond Mill:Ndi ndalama zochepa zogulira, kutulutsa kwakukulu, kugwiritsa ntchito mphamvu zochepa, zida zokhazikika komanso ndalama zochepa zosamalira, ndi zida zabwino kwambiri zopukutira mafuta a coke;
Mphero yoyima:ndalama zambiri zogulira, kutulutsa zinthu zambiri komanso kugwiritsa ntchito mphamvu zambiri;
Mphero yopangira mphamvu:ndalama zochepa zogulira, zotulutsa zochepa, kugwiritsa ntchito mphamvu zambiri, kulephera kwa zida zambiri komanso ndalama zambiri zokonzera;
Kusanthula kwa mitundu ya mphero yopera
Ubwino wa mphero yopukusira ya HC series mu petroleum coke pulverizing:
1. Mphero ya HC Petroleum Coke Kapangidwe kake: kupanikizika kwakukulu kogayira ndi kutulutsa kwakukulu, komwe kuli kokwera ndi 30% kuposa kwa mphero wamba wa pendulum. Kutulutsa kwake kuli kokwera ndi 200% kuposa kwa mphero yogunda.
2. Kulondola kwambiri kwa gulu: kupyapyala kwa chinthu nthawi zambiri kumafuna maukonde 200 (D90), ndipo ngati chili chokwera, chidzafika maukonde 200 (D99).
3. Makina opukusira ali ndi phokoso lochepa, kugwedezeka kochepa komanso chitetezo cha chilengedwe chimagwira ntchito bwino kwambiri.
4. Kukonza kotsika, kukonza kosavuta komanso ndalama zochepa zogwirira ntchito.
5. Malinga ndi zofunikira pa ndondomekoyi, makina opangira mphero amatha kudutsa mpweya wotentha wa 300 ° C kuti apange kuyanika ndi kupera (monga momwe zilili ndi zipangizo zomangira za Three Gorges).
Ndemanga: Pakadali pano, HC1300 ndi HC1700 mphero yopukusira ili ndi gawo la msika loposa 90% pankhani yopukusira mafuta a coke.
Gawo Loyamba:Ckuthamanga kwa zinthu zopangira
Lalikulucoke ya petroleumChipangizocho chimaphwanyidwa ndi chotsukira mpaka kufika pamlingo wochepa (15mm-50mm) womwe ungalowe mu mphero yopera.
GawoII: Gkupukuta
Wophwanyidwacoke ya petroleumZipangizo zazing'ono zimatumizidwa ku hopper yosungiramo zinthu ndi elevator, kenako zimatumizidwa ku chipinda chopukusira cha mphero mofanana komanso mochuluka ndi chodyetsera kuti chipukute.

Ufa wofanana ndi kupyapyala umadutsa mu payipi pamodzi ndi mpweya ndipo umalowa mu chosonkhanitsira fumbi kuti ulekanitsidwe ndi kutengedwa. Ufa womalizidwa wosonkhanitsidwa umatumizidwa ku silo ya chinthu chomalizidwa ndi chipangizo chonyamulira kudzera mu doko lotulutsira, kenako nkupachikidwa ndi chosungira ufa kapena chopakira chokha.
Zitsanzo za kugwiritsa ntchito ufa wa petroleum coke
Chitsanzo ndi chiwerengero cha zida izi: mizere itatu yopangira ya HC2000
Kukonza zinthu zopangira: pellet coke ndi sponge coke
Kusalala kwa chinthu chomalizidwa: 200 mesh D95
Mphamvu: 14-20t / h
Mwiniwake wa polojekitiyi wayang'ana zida zomwe zimagwiritsidwa ntchito popanga makina opera mafuta a coke kwa nthawi zambiri. Poyerekeza bwino ndi opanga makina ambiri opera mafuta, agula makina ambiri opera mafuta a Guilin Hongcheng HC1700 ndi makina opera mafuta a HC2000 motsatizana, ndipo akhala akugwirizana komanso ogwirizana ndi Guilin Hongcheng kwa zaka zambiri. M'zaka zaposachedwa, mizere yambiri yatsopano yopangira magalasi yamangidwa. Guilin Hongcheng yatumiza mainjiniya kumalo a kasitomala kangapo malinga ndi zosowa za mwiniwake. Zipangizo zopera mafuta a Guilin Hongcheng zakhala zikugwiritsidwa ntchito m'mapulojekiti opera mafuta a coke m'fakitale yagalasi m'zaka zitatu zapitazi. Mzere wopangira mafuta a coke opera mafuta womwe unapangidwa ndi Guilin Hongcheng uli ndi ntchito yokhazikika, mphamvu zambiri, mphamvu zochepa komanso kuipitsa fumbi pang'ono m'malo opera mafuta, zomwe zayamikiridwa kwambiri ndi makasitomala.
