Isingeniso ku-petroleum coke
I-petroleum coke iyi-distillation yokuhlukanisa amafutha alula nasindayo, amafutha asindayo aphenduka umkhiqizo wokugcina ngenqubo yokuqhekeka kokushisa. Uma ubheka ukubukeka kwayo, i-coke ayijwayelekile ngesimo nangobukhulu bezigaxa ezimnyama (noma izinhlayiya) ukukhazimula kwensimbi; izinhlayiya ze-coke zinesakhiwo esinezimbobo, izakhi eziyinhloko yi-carbon, zingaphezu kwama-80wt%, okunye yi-hydrogen, i-oxygen, i-nitrogen, i-sulfur kanye nezakhi zensimbi. Izakhi zamakhemikhali ze-petroleum coke ezinezakhi zayo zomzimba nezamakhemikhali ezihlukile kanye nezakhiwo zemishini. I-carbon engaguquki eyingxenye yokushisa kwayo, izinto eziguquguqukayo kanye nokungcola kwamaminerali (i-sulfur, izakhi zensimbi, amanzi, umlotha, njll.), zonke lezo zinkomba zinquma izakhi zamakhemikhali ze-coke.
I-coke yenaliti:inesakhiwo senaliti esicacile kanye nokuthungwa kwefayibha, iningi layo lisetshenziswa njenge-electrode ye-graphite enamandla aphezulu ekwenzeni insimbi. I-needle coke inemfuneko eqinile yekhwalithi yokuqukethwe kwesulfure, okuqukethwe komlotha, ukuguquguquka kanye nokuqina kweqiniso njll., ukuze kube nezidingo ezikhethekile zobuciko bokucubungula i-needle coke kanye nezinto zokusetshenziswa.
I-Sponge coke:ukusabela kwamakhemikhali okuphezulu, okuqukethwe okuphansi kokungcola, okusetshenziswa kakhulu embonini ye-aluminium kanye nemboni yekhabhoni.
I-coke edutshulwayo noma i-coke e-globular:isimo esiyindilinga esiyindilinga, ububanzi obungu-0.6-30mm, ngokuvamile esikhiqizwa yi-residue ye-asphalt ene-sulfur ephezulu, ingasetshenziswa kuphela ekukhiqizeni ugesi, usimende kanye nophethiloli wezimboni.
I-coke ewuphuphu:Njengoba ikhiqizwa ngokucubungula okune-fluidized coking, izinhlayiya zincane (ububanzi obungu-0.1-0.4mm), i-volatible ephezulu kanye ne-thermal expansion coefficient yenza ingasetshenziswa ngqo kuma-electrode kanye nasembonini yekhabhoni.
Ukusetshenziswa kwe-Petroleum coke
Insimu eyinhloko yokusetshenziswa kwe-petroleum coke eShayina imboni ye-aluminium ye-electrolytic, ebiza ngaphezu kwama-65% okusetshenziswa okuphelele kwe-petroleum coke. Kulandelwa yi-carbon, i-silicon yezimboni kanye nezinye izimboni zokuncibilikisa. I-petroleum coke isetshenziswa kakhulu njengophethiloli kusimende, ekukhiqizeni ugesi, engilazini nakwezinye izimboni, okubalwa ingxenye encane. Njengamanje, ukuhlinzekwa kanye nesidingo se-petroleum coke yasekhaya kuyafana. Kodwa-ke, ngenxa yokuthunyelwa kwenani elikhulu le-petroleum coke ephansi ye-sulfur ephezulu, ukuhlinzekwa okuphelele kwe-petroleum coke yasekhaya akwanele, futhi i-petroleum coke ye-sulfur ephakathi nendawo nephezulu idinga ukungeniswa ukuze ingezwe. Ngokwakhiwa kwenani elikhulu lamayunithi e-coking eminyakeni yamuva nje, umkhiqizo we-petroleum coke yasekhaya uzothuthukiswa futhi wandiswe.
①Imboni yengilazi iyimboni esetshenziswa kakhulu amandla. Izindleko zayo zikaphethiloli zibiza cishe u-35% ~ 50% wezindleko zengilazi. Isithando sengilazi siwumshini osebenzisa amandla amaningi emgqeni wokukhiqiza ingilazi. ② Uma isithando sengilazi sesishisiwe, asikwazi ukuvalwa kuze kube yilapho isithando senziwe kabusha (iminyaka engu-3-5). Ngakho-ke, uphethiloli kumele wengezwe njalo ukuqinisekisa izinga lokushisa lesithando lamadigri ayizinkulungwane esithandweni. Ngakho-ke, indawo yokusebenzela yokugaya ejwayelekile izoba nemishini yokugaya emile ukuqinisekisa ukukhiqizwa okuqhubekayo. ③ Impuphu ye-coke kaphethiloli isetshenziswa embonini yengilazi, futhi ubuncane buyadingeka ukuthi bube yi-200 mesh D90. ④ Okuqukethwe kwamanzi kwe-coke eluhlaza ngokuvamile kungu-8% - 15%, futhi idinga ukomiswa ngaphambi kokungena emshinini wokugaya. ⑤ Uma okuqukethwe komswakama komkhiqizo oqediwe kuphansi, kungcono. Ngokuvamile, umphumela wokuphelelwa amanzi emzimbeni wesistimu yesekethe evulekile ungcono.
Ukugeleza kwenqubo yokugaya i-petroleum coke
Ipharamitha ebalulekile yokugaya i-petroleum coke
| Isici sokugoba | Umswakama oyinhloko (%) | Umswakama wokuphela (%) |
| ＞100 | ≤6 | ≤3 |
| ＞90 | ≤6 | ≤3 |
| ＞80 | ≤6 | ≤3 |
| ＞70 | ≤6 | ≤3 |
| ＞60 | ≤6 | ≤3 |
| ＜40 | ≤6 | ≤3 |
Amazwi:
1. Ipharamitha ye-grindable coefficient yezinto ze-petroleum coke iyisici esithinta umphumela womshini wokugaya. Uma i-grindable coefficient iphansi, umphumela uba phansi;
- Umswakama wokuqala wezinto zokusetshenziswa ngokuvamile u-6%. Uma okuqukethwe komswakama wezinto zokusetshenziswa kungaphezu kuka-6%, umshini wokomisa noma umshini wokugaya ungaklanywa ngomoya oshisayo ukuze kuncishiswe okuqukethwe komswakama, ukuze kuthuthukiswe umkhiqizo kanye nekhwalithi yemikhiqizo eqediwe.
Uhlelo lokukhetha imodeli yomshini wokwenza i-petroleum coke powder
| 200mesh D90 | Isigayo sikaRaymond |
|
| Umshini Wokugaya Ojikelezayo Oqondile | I-1250 Vertical Roller Mill isetshenziswa eXiangfan, isetshenziswa kakhulu ngenxa yohlobo lwayo lwakudala futhi ayibuyekezwa iminyaka eminingi. Okukhathalela amakhasimende umsebenzi wokudlula emoyeni oshisayo. | |
| Isigayo sokushaya | Isabelo semakethe esingu-80% eMianyang, eSichuan naseSuowei, eShanghai ngaphambi kuka-2009, siyaphela manje. |
Ukuhlaziywa kwezinzuzo kanye nokungalungi kwemishini yokugaya ehlukahlukene:
URaymond Mill:ngezindleko zokutshalwa kwezimali eziphansi, umkhiqizo ophezulu, ukusetshenziswa kwamandla okuphansi, imishini ezinzile kanye nezindleko zokulungisa eziphansi, iyimishini efanelekile yokugaya i-petroleum coke;
Isigayo esiqondile:izindleko zokutshalwa kwezimali eziphezulu, umkhiqizo ophezulu kanye nokusetshenziswa kwamandla aphezulu;
Umshini wokugaya impact:izindleko zokutshalwa kwezimali eziphansi, umkhiqizo ophansi, ukusetshenziswa kwamandla aphezulu, izinga eliphezulu lokwehluleka kwemishini kanye nezindleko eziphezulu zokulungisa;
Ukuhlaziywa kwamamodeli okugaya
Izinzuzo zomshini wokugaya uchungechunge lwe-HC ekugayweni kwe-petroleum coke:
1. Isigayo se-HC Petroleum Coke isakhiwo: ukucindezela okuphezulu kokugaya kanye nokukhipha okuphezulu, okuphakeme ngo-30% kunokomshini ojwayelekile we-pendulum. Ukukhipha kuphakeme ngo-200% kunomshini wokugaya othintayo.
2. Ukunemba okuphezulu kokuhlukaniswa: ubuncane bomkhiqizo ngokuvamile budinga i-mesh engu-200 (D90), futhi uma iphakeme, izofinyelela i-mesh engu-200 (D99).
3. Uhlelo lokugaya lunomsindo ophansi, ukudlidliza okuphansi kanye nokusebenza okuphezulu kokuvikela imvelo.
4. Izinga lokulungisa eliphansi, ukulungiswa okulula kanye nezindleko eziphansi zabasebenzi.
5. Ngokwezidingo zenqubo, uhlelo lokugaya lungadlula umoya oshisayo ongu-300 ° C ukuze kufezwe ukukhiqizwa kokomisa nokugaya (njengezinto zokwakha ze-Three Gorges).
Amazwana: njengamanje, umshini wokugaya we-HC1300 kanye ne-HC1700 unesabelo semakethe esingaphezu kuka-90% emkhakheni wokugaya i-petroleum coke.
Isigaba I:Cukushesha kwezinto zokusetshenziswa
Inkului-coke kaphethiloliIzinto ezisetshenziswayo zichotshozwa yi-crusher kuze kube yilapho zinobuncane bokuphakela (15mm-50mm) obungangena emshinini wokugaya.
IsitejiII: Gukugoqa
Abachotshoziwei-coke kaphethiloliIzinto ezincane zithunyelwa endaweni yokugcina izinto nge-lifti, bese zithunyelwa ekamelweni lokugaya lesitsha ngokulinganayo nangobuningi yi-feeder ukuze zigaywe.
Isigaba III:Hlela ngezigabaing
Izinto ezigayiwe zilinganiswa ngohlelo lokulinganisa, kanti impuphu engafaneleki ilinganiswa ngohlelo lokuhlukanisa bese ibuyiselwa emshinini oyinhloko ukuze igaywe kabusha.
IsitejiV: Cukuqoqwa kwemikhiqizo eqediwe
Impuphu evumelana nobuncane igeleza ngepayipi kanye negesi bese ingena eqoqweni lokuqoqa uthuli ukuze ihlukaniswe futhi iqoqwe. Impuphu eqoqwe ithunyelwa esigungwini somkhiqizo oqediwe ngedivayisi yokudlulisa ngembobo yokukhipha, bese ipakishwa yithangi lempuphu noma i-automatic packer.
Izibonelo zokusetshenziswa kokucubungula i-petroleum coke powder
Imodeli nenani lale mishini: Imigqa yokukhiqiza engu-3 HC2000
Ukucubungula izinto zokusetshenziswa: i-pellet coke kanye ne-sponge coke
Ubuncane bomkhiqizo oqediwe: 200 mesh D95
Umthamo: 14-20t / h
Umnikazi wephrojekthi uhlole ukukhethwa kwemishini yesigayo sokugaya i-petroleum coke izikhathi eziningi. Ngokuqhathanisa okuphelele nabakhiqizi bemishini eminingi yokugaya, bathenge amasethi amaningi omshini wokugaya i-Guilin Hongcheng HC1700 kanye nemishini yokugaya i-HC2000 ngokulandelana, futhi bebenobungane futhi bebambisana noGuilin Hongcheng iminyaka eminingi. Eminyakeni yamuva nje, kwakhiwa imigqa eminingi emisha yokukhiqiza ingilazi. UGuilin Hongcheng uthumele onjiniyela endaweni yamakhasimende izikhathi eziningi ngokwezidingo zomnikazi. Imishini yesigayo sokugaya i-Guilin Hongcheng isetshenziswe kumaphrojekthi okugaya i-petroleum coke efektri yengilazi eminyakeni emithathu edlule. Umugqa wokukhiqiza i-petroleum coke oklanywe nguGuilin Hongcheng usebenza kahle, ukhiqiza kakhulu, ukusetshenziswa kwamandla aphansi kanye nokungcola okuncane kothuli endaweni yokusebenzela yokugaya, okuye kwanconywa kakhulu ngamakhasimende.
