Isingeniso ku-petroleum coke
I-Petroleum coke i-distillation ukuhlukanisa amafutha alula namafutha asindayo, uwoyela osindayo uphenduka umkhiqizo wokugcina ngenqubo yokuqhekeka okushisayo.Tshela ngokubukeka, i-coke ayifani ngendlela futhi nobukhulu bezigaxa ezimnyama (noma izinhlayiya) i-metallic luster;izinhlayiya ze-coke ezinokwakheka kwe-porous, izakhi eziyinhloko yikhabhoni, ephethe ngaphezu kuka-80wt%, enye i-hydrogen, umoya-mpilo, i-nitrogen, isulfure kanye nezakhi zensimbi.Izakhiwo zamakhemikhali ze-petroleum coke nezakhiwo zayo ezihlukile zomzimba namakhemikhali kanye nezakhiwo zemishini.Ikhabhoni engaguquguquki eyingxenye yokushisa kwayo, izinto eziguquguqukayo kanye nokungcola kwamaminerali (sulfure, izinhlanganisela zensimbi, amanzi, umlotha, njll.), zonke lezo zinkomba zinquma izici zamakhemikhali ze-coke.
Inaliti ye-coke:babe nesakhiwo senaliti esisobala kanye nokuthungwa kwefayibha, iningi lisetshenziswa njengamandla aphezulu e-graphite electrode ekwenzeni insimbi.I-coke yenaliti inesidingo esiqinile sekhwalithi kokuqukethwe kwesibabule, okuqukethwe komlotha, ukuminyana okuguquguqukayo nokuyiqiniso njll, ukuze kube nesidingo esikhethekile sokucubungula ubuciko benaliti ye-coke kanye nezinto ezingavuthiwe.
I-sponge coke:high chemical reactivity, low ukungcola okuqukethwe, ikakhulukazi esetshenziswa embonini aluminium kanye carbon.
I-Shot coke noma i-globular coke:i-cylindrical spherical shape, ububanzi obuyi-0.6-30mm, ngokuvamile ekhiqizwa yi-high-sulfur, insalela ephezulu ye-asphalting, ingasetshenziswa kuphela ukukhiqiza amandla, usimende namanye amafutha ezimboni.
I-powder coke:ekhiqizwa ngokusebenzisa ukucutshungulwa kwe-coking e-fluidized, izinhlayiya zilungile (ububanzi be-0.1-0.4mm), i-coefficient ephezulu eguquguqukayo kanye ne-thermal yokwandisa yenza ingakwazi ukusetshenziswa ngokuqondile kuma-electrode kanye nemboni ye-carbon.
Ukusetshenziswa kwe-Petroleum coke
Inkambu eyinhloko yokusetshenziswa kwe-petroleum coke e-China imboni ye-electrolytic aluminium, ibalwa ngaphezu kwama-65% okusetshenziswa okuphelele kwe-petroleum coke.Kulandelwa ikhabhoni, i-silicon yezimboni nezinye izimboni zokuncibilikisa.I-petroleum coke isetshenziswa kakhulu njengophethiloli kusimende, ukuphehla ugesi, ingilazi nezinye izimboni, kubalwa ingxenye encane.Njengamanje, ukuhlinzekwa kanye nesidingo se-coke ye-petroleum yasekhaya kuyefana.Kodwa-ke, ngenxa yokuthunyelwa kwamanye amazwe kwenani elikhulu le-coke ye-petroleum coke ene-sulphur ene-high-end high-end, ukutholakala okuphelele kwe-coke ye-petroleum yasekhaya akwanele, futhi i-coke ye-sulphur petroleum ephakathi nendawo nephezulu idinga ukungeniswa kwamanye amazwe ukuze yengezwe.Ngokwakhiwa kwenani elikhulu lamayunithi okupheka eminyakeni yamuva, ukukhishwa kwe-coke ye-petroleum yasekhaya kuzothuthukiswa futhi kwandiswe.
①Imboni yengilazi iyimboni esetshenziswa kakhulu amandla.Izindleko zayo zikaphethiloli zibalelwa ku-35% ~ 50% wezindleko zengilazi.I-Glass furnace iyimishini esebenzisa amandla amaningi kulayini wokukhiqiza ingilazi.② Uma isithando somlilo sengilazi sivutha, asikwazi ukuvalwa kuze kube yilapho isithando somlilo silungiswa kabusha (iminyaka engu-3-5).Ngakho-ke, uphethiloli kufanele wengezwe ngokuqhubekayo ukuze kuqinisekiswe izinga lokushisa lomlilo lezinkulungwane zamadigri esithandweni somlilo.Ngakho-ke, ishabhu evamile yokuhlikihla izoba nezigayo ezilindile ukuze kuqinisekiswe ukukhiqizwa okuqhubekayo.③ I-petroleum coke powder isetshenziswa embonini yengilazi, futhi ubucwebe budingeka ukuthi kube yi-200 mesh D90.④ Amanzi e-coke eluhlaza ngokuvamile angu-8% - 15%, futhi kudingeka omiswe ngaphambi kokungena emshinini wokugaya.⑤ Ukwehlisa umswakama womkhiqizo oqediwe, kuba ngcono.Ngokuvamile, umphumela wokuphelelwa amanzi emzimbeni wesistimu yesifunda evulekile ungcono.
Ukugeleza kwenqubo ye-petroleum coke pulverization
Ipharamitha eyinhloko yokugaya i-coke ye-petroleum
| Isici sokugaya | Umswakama oyinhloko (%) | Qeda umswakama (%) |
| ＞100 | ≤6 | ≤3 |
| ＞90 | ≤6 | ≤3 |
| ＞80 | ≤6 | ≤3 |
| ＞70 | ≤6 | ≤3 |
| ＞60 | ≤6 | ≤3 |
| ＜40 | ≤6 | ≤3 |
Amazwana:
1. Ipharamitha ye-coefficient egayayo yezinto ze-petroleum coke iyisici esithinta ukuphuma komshini wokugaya.Lapho i-coefficient egayayo iphansi, i-output iyancipha;
- Umswakama wokuqala wezinto zokusetshenziswa ngokuvamile u-6%.Uma umswakama wezinto ezingavuthiwe ungaphezu kuka-6%, umshini wokomisa noma umshini wokugaya ungaklanywa ngomoya oshisayo ukuze unciphise umswakama, ukuze kuthuthukiswe ukuphuma kanye nekhwalithi yemikhiqizo eqediwe.
Uhlelo lokukhetha imodeli yomshini we-petroleum coke powder
| 200mesh D90 | Raymond Mill |
|
| I-Vertical Roller Mill | I-1250 Vertical Roller Mill isetshenziswa e-Xiangfan, isetshenziswa kakhulu amandla ngenxa yohlobo lwayo oludala futhi ngaphandle kokubuyekezwa iminyaka.Okukhathalelwa yikhasimende wumsebenzi wokungena emoyeni oshisayo. | |
| Isigayo somthelela | Isabelo semakethe esingu-80% eMianyang, eSichuan naseSuowei, e-Shanghai ngaphambi kuka-2009, siyaphela manje. |
Ukuhlaziywa kwezinzuzo kanye nokubi kwezigayo ezihlukahlukene zokugaya:
Raymond Mill:ngezindleko eziphansi zokutshalwa kwezimali, okukhiphayo okuphezulu, ukusetshenziswa kwamandla okuphansi, okokusebenza okuzinzile kanye nezindleko eziphansi zokuyilungisa, iyithuluzi elikahle lokugaya i-petroleum coke pulverization;
Isigayo esiqondile:izindleko eziphezulu zokutshala izimali, umkhiqizo ophezulu kanye nokusetshenziswa kwamandla okuphezulu;
Isigayo somthelela:izindleko eziphansi zokutshalwa kwezimali, ukukhishwa okuphansi, ukusetshenziswa kwamandla okuphezulu, izinga eliphezulu lokuhluleka kwemishini kanye nezindleko zokuyilungisa;
Ukuhlaziywa kwamamodeli wokugaya
Izinzuzo ze-HC series grinding mill ku-petroleum coke pulverizing:
1. I-HC Petroleum Coke Mill isakhiwo: ukucindezela okuphezulu kokugaya kanye nokukhishwa okuphezulu, okungama-30% aphezulu kunalowo we-pendulum mill evamile.Okukhiphayo kungaphezulu kuka-200% ngaphezu kwalowo we- impact mill.
2. Ukunemba kwezigaba eziphezulu: ukucoleka komkhiqizo ngokuvamile kudinga i-200 mesh (D90), futhi uma iphakeme, izofinyelela ku-200 mesh (D99).
3. Isistimu yokugaya inomsindo ophansi, ukudlidliza okuphansi nokusebenza okuphezulu kokuvikela imvelo.
4. Izinga lokulungisa eliphansi, ukunakekelwa okufanele kanye nezindleko eziphansi zabasebenzi.
5. Ngokwezidingo zenqubo, isistimu yokugaya ingadlula umoya oshisayo ongu-300 ° C ukuze ibone ukukhiqizwa kokumisa nokugaya (icala lezinto zokwakha ze-Three Gorges).
Ukuphawula: okwamanje, i-HC1300 kanye ne-HC1700 yokugaya inesabelo semakethe esingaphezu kuka-90% emkhakheni we-petroleum coke pulverization.
Isigaba I:Cukuphuthuma kwezinto zokusetshenziswa
Enkului-petroleum cokeimpahla igaywa yi-crusher kuze kube yi-feed fineness (15mm-50mm) engangena emshinini wokugaya.
IsitejiII: Gukugoqa
Ochotshoziwei-petroleum cokeizinto ezincane zithunyelwa ku-hopper yokugcina nge-elevator, bese zithunyelwa ekamelweni lokugaya le-mill ngokulinganayo futhi ngobuningi yi-feeder yokugaya.
Isigaba III:Hlelaing
Izinto ezigayiwe zihlelwa ngesistimu yokugreda, futhi impushana engafanelekile ihlelwa ngokwezigaba bese ibuyiselwa emshinini omkhulu ukuze igaywe kabusha.
IsitejiV: Cukuqoqwa kwemikhiqizo eqediwe
Impushana ehambisana nokucoleka igeleza epayipini negesi futhi ingene endaweni eqoqwa uthuli ukuze ihlukaniswe futhi iqoqwe.Impushana eqoqiwe eqoqiwe ithunyelwa esiseleni somkhiqizo oqediwe ngomshini owudluliselayo ngembobo yokukhipha, bese ihlanganiswa ne-powder tanker noma i-automatic packer.
Izibonelo zokusetshenziswa kwe-petroleum coke powder processing
Imodeli nenombolo yale mishini: 3 HC2000 imigqa yokukhiqiza
Ukucubungula izinto zokusetshenziswa: i-pellet coke ne-sponge coke
Ubuhle bomkhiqizo ophelile: 200 mesh D95
