Taw qhia rau roj av coke
Petroleum coke yog distillation cais lub teeb thiab hnyav roj, hnyav roj tig mus rau hauv cov khoom kawg los ntawm thermal cracking txheej txheem.Qhia los ntawm cov tsos, coke tsis zoo nyob rau hauv cov duab thiab qhov ntau thiab tsawg ntawm cov pob dub (los yog hais) ib qho xim hlau luster;coke hais muaj cov qauv ntxeem tau, cov ntsiab lus tseem ceeb yog carbon, muaj ntau tshaj 80wt%, tus so yog hydrogen, oxygen, nitrogen, sulfur thiab hlau ntsiab.Cov khoom siv tshuaj lom neeg ntawm cov roj av coke nrog nws cov khoom siv lub cev thiab tshuaj lom neeg thiab cov khoom siv tshuab.Cov pa roj carbon uas tsis yog-volatile uas yog cua sov ib feem ntawm nws tus kheej, volatile teeb meem thiab ntxhia impurities (sulfur, hlau tebchaw, dej, tshauv, thiab lwm yam), tag nrho cov ntsuas no txiav txim siab coke cov tshuaj muaj pes tsawg leeg.
Koob coke:muaj qhov pom tseeb koob qauv thiab fiber ntau kev ntxhib los mos, feem ntau siv raws li lub zog siab graphite electrode hauv steel-ua.Rau koob coke muaj nruj zoo yuav tsum tau nyob rau hauv sulfur cov ntsiab lus, cov ntsiab lus tshauv, volatile thiab muaj tseeb ceev thiab lwm yam, thiaj li hais tias muaj tshwj xeeb yuav tsum tau rau rab koob coke txoj kev ua art thiab raw khoom.
Daim txhuam cev coke:siab tshuaj reactivity, tsis muaj impurity cov ntsiab lus, feem ntau yog siv nyob rau hauv txhuas kev lag luam thiab carbon kev lag luam.
Txhaj tshuaj coke los yog globular coke:cylindrical kheej kheej, txoj kab uas hla ntawm 0.6-30mm, feem ntau yog tsim los ntawm high-sulfur, siab asphalting residue, nws tsuas yog siv rau lub zog tsim, cement thiab lwm yam roj muaj roj.
hmoov coke:ua los ntawm kev ua kua dej coking, cov khoom ua tau zoo (inch ntawm 0.1-0.4mm), siab volatile thiab thermal expansion coefficient ua rau nws tsis tuaj yeem siv ncaj qha rau hauv electrodes thiab carbon kev lag luam.
Kev siv Petroleum coke
Daim ntawv thov kev lag luam tseem ceeb ntawm roj av coke hauv Suav teb yog electrolytic aluminium kev lag luam, suav txog ntau dua 65% ntawm tag nrho cov kev siv roj av coke.Ua raws li cov pa roj carbon, muaj silicon thiab lwm yam kev lag luam smelting.Petroleum coke feem ntau yog siv los ua roj hauv cov cement, lub zog tsim hluav taws xob, iav thiab lwm yam kev lag luam, suav nrog ib feem me me.Tam sim no, cov khoom siv thiab kev xav tau ntawm cov roj av coke hauv tsev yog tib yam.Txawm li cas los xij, vim tias kev xa tawm ntau ntawm cov tsis tshua muaj sulfur high-end petroleum coke, tag nrho cov khoom siv roj av hauv tsev tsis txaus, thiab cov roj av nruab nrab thiab siab sulfur coke yuav tsum tau xa tuaj ntxiv.Nrog rau kev tsim kho ntawm ntau lub coking units nyob rau hauv xyoo tas los no, cov zis ntawm domestic roj av coke yuav raug txhim kho thiab nthuav.
① Kev lag luam iav yog kev lag luam siv hluav taws xob siab.Nws cov nqi roj suav txog li 35% ~ 50% ntawm tus nqi iav.Iav rauv yog ib qho khoom siv nrog ntau lub zog siv hauv iav ntau lawm kab.② Thaum lub khob rauv taws kub hnyiab, nws tsis tuaj yeem kaw kom txog thaum lub cub tawg tau kho dua tshiab (3-5 xyoos).Yog li ntawd, roj yuav tsum tau txuas ntxiv mus ntxiv kom ntseeg tau tias lub cub tawg kub ntawm ntau txhiab degrees hauv qhov cub.Yog li ntawd, lub rooj cob qhia dav dav pulverizing yuav muaj cov mills standby los xyuas kom meej ntau lawm.③ Petroleum coke hmoov yog siv rau hauv kev lag luam iav, thiab qhov zoo yuav tsum yog 200 mesh D90.④ Cov dej ntsiab lus ntawm cov coke nyoos feem ntau yog 8% - 15%, thiab nws yuav tsum tau qhuav ua ntej nkag mus rau hauv lub zeb.⑤ Qhov qis dua cov dej noo ntawm cov khoom tiav, qhov zoo dua.Feem ntau, lub cev qhuav dej ntawm qhov qhib Circuit Court yog qhov zoo dua.
Cov txheej txheem ntws ntawm roj av coke pulverization
Qhov tseem ceeb parameter ntawm petroleum coke sib tsoo
| Grindability factor | Thawj qhov dej noo (%) | Xaus noo noo (%) |
| ＞ 100 | ≤ 6 | ≤ 3 |
| ～ 90 | ≤ 6 | ≤ 3 |
| 80 | ≤ 6 | ≤ 3 |
| ;70 | ≤ 6 | ≤ 3 |
| 60 | ≤ 6 | ≤ 3 |
| 40 | ≤ 6 | ≤ 3 |
Lus ceeb toom:
1. Lub grindable coefficient parameter ntawm cov khoom siv roj av coke yog qhov cuam tshuam rau cov khoom siv sib tsoo.Qhov qis ntawm grindable coefficient, qhov tso zis qis dua;
- Qhov pib ya raws ntawm raw cov ntaub ntawv feem ntau yog 6%.Yog tias cov dej noo ntawm cov ntaub ntawv raw yog siab dua 6%, lub tshuab ziab khaub ncaws lossis zeb tuaj yeem tsim nrog cua kub kom txo cov dej noo, txhawm rau txhim kho cov khoom tsim tawm thiab zoo ntawm cov khoom tiav.
Petroleum coke hmoov ua tshuab qauv xaiv qhov kev pab cuam
| 200 mesh D90 | Raymond zeb |
|
| Vertical Roller Mill | 1250 Vertical Roller Mill yog siv nyob rau hauv Xiangfan, nws yog lub zog siv zog vim nws hom qub thiab tsis hloov kho rau xyoo.Dab tsi cov neeg mob saib xyuas yog kev ua haujlwm ntawm huab cua kub. | |
| Impact zeb | Kev lag luam feem ntawm 80% hauv Mianyang, Sichuan thiab Suowei, Shanghai ua ntej 2009, nws tau tshem tawm tam sim no. |
Kev txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm ntau yam sib tsoo mills:
Raymond Mill:nrog cov nqi peev tsawg, cov zis siab, kev siv hluav taws xob tsawg, cov khoom siv ruaj khov thiab cov nqi kho mob qis, nws yog cov cuab yeej zoo tshaj plaws rau roj av coke pulverization;
Vertical zeb:tus nqi peev, siab tso zis thiab siab zog noj;
Impact zeb:Tus nqi qis peev, cov khoom siv qis, kev siv hluav taws xob ntau, cov khoom siv tsis ua haujlwm siab thiab tus nqi tu siab;
Kev tsom xam ntawm kev sib tsoo zeb qauv
Qhov zoo ntawm HC series sib tsoo zeb hauv roj av coke pulverizing:
1. HC Petroleum Coke mills qauv: siab sib tsoo siab thiab cov zis siab, uas yog 30% siab dua li cov pendulum zeb zoo tib yam.Cov zis ntau tshaj 200% siab tshaj qhov cuam tshuam zeb.
2. High classification precision: cov khoom fineness feem ntau yuav tsum tau 200 mesh (D90), thiab yog hais tias nws siab dua, nws yuav ncav cuag 200 mesh (D99).
3. Lub tshuab sib tsoo tshuab muaj suab nrov, tsis tshua muaj kev vibration thiab kev tiv thaiv ib puag ncig zoo.
4. Tsawg txij nkawm tus nqi, yooj yim txij nkawm thiab tus nqi qis zog.
5. Raws li cov txheej txheem yuav tsum tau, lub tshuab zeb tuaj yeem dhau 300 ° C cua kub kom paub txog kev ziab thiab sib tsoo (cov ntaub ntawv ntawm Peb Gorges cov khoom siv hauv tsev).
Lus Cim: tam sim no, HC1300 thiab HC1700 sib tsoo zeb muaj kev lag luam feem ntau tshaj 90% hauv kev lag luam roj av coke pulverization.
Theem I:Crushing ntawm raw khoom
Qhov lojroj av cokecov khoom yog crushed los ntawm lub crusher mus rau lub pub fineness (15mm-50mm) uas tuaj yeem nkag mus rau hauv kev sib tsoo zeb.
TheemII: Gnkim
Lub crushedroj av cokeCov ntaub ntawv me me raug xa mus rau lub hopper cia los ntawm lub elevator, thiab tom qab ntawd xa mus rau qhov sib tsoo chamber ntawm lub zeb sib npaug thiab ntau npaum li cas los ntawm feeder rau kev sib tsoo.
Theem III:Muab faibhauv
Cov ntaub ntawv milled tau muab qhab nia los ntawm kev muab qhab nia, thiab cov hmoov tsis tsim nyog tau muab qhab nia los ntawm cov khoom faib thiab rov qab mus rau lub tshuab tseem ceeb rau kev sib tsoo.
TheemV: Collection ntawm cov khoom tiav
Cov hmoov ua raws li kev nplua nuj ntws los ntawm cov raj xa dej nrog cov roj thiab nkag mus rau hauv cov plua plav collector rau kev sib cais thiab sib sau.Cov hmoov uas tau sau tiav yog xa mus rau cov khoom tiav silo los ntawm cov khoom siv thauj khoom los ntawm qhov chaw nres nkoj tawm, thiab tom qab ntawd ntim los ntawm cov hmoov tanker lossis tsis siv neeg ntim khoom.
Daim ntawv thov piv txwv ntawm roj av coke hmoov ua
Qauv thiab tus naj npawb ntawm cov khoom siv no: 3 HC2000 cov kab ntau lawm
Cov khoom siv raw: pellet coke thiab daim txhuam cev coke
Fineness ntawm cov khoom tiav: 200 mesh D95
Peev xwm: 14-20t / h
Tus tswv ntawm qhov project tau tshuaj xyuas cov cuab yeej xaiv cov roj av coke sib tsoo zeb rau ntau zaus.Los ntawm kev sib piv nrog ntau lub tshuab milling manufacturers, lawv tau ua tiav ntau cov khoom ntawm Guilin Hongcheng HC1700 milling tshuab thiab HC2000 milling tshuab khoom, thiab tau ua phooj ywg thiab koom tes nrog Guilin Hongcheng tau ntau xyoo.Nyob rau hauv xyoo tas los no, ntau cov iav tshiab tsim tau tsim.Guilin Hongcheng tau xa engineers mus rau cov neeg siv khoom qhov chaw ntau zaus raws li qhov xav tau ntawm tus tswv.Guilin Hongcheng sib tsoo zeb khoom siv tau siv rau hauv cov roj av coke pulverizing tej yaam num ntawm iav Hoobkas nyob rau hauv peb lub xyoos tsis ntev los no.Cov roj av coke pulverizing ntau lawm kab tsim los ntawm Guilin Hongcheng muaj kev ua haujlwm ruaj khov, cov khoom siv siab, kev siv hluav taws xob tsawg thiab tsis muaj plua plav paug hauv pulverizing Rhiav, uas tau txais kev qhuas los ntawm cov neeg siv khoom.
