Sechinhu chakakosha chezvigadzirwa zvemazuva ano indasitiri yemakemikari, iyo yepamusoro-tembiricha calcination process yepetroleum coke ine kukosha kwakakosha pamhando uye goho repetroleum coke. Mupepa iri, tekinoroji yekuverengera tembiricha yepetroleum coke inokurukurwa pamwe chete nekukosha kwayo kwekugadzira. Zvekureva zvemabhizinesi.
Kukosha kwekugadzirwa kwepetroleum coke nepamusoro-tembiricha calcination
Calcination ye petroleum coke ndiyo imwe yenzira huru mukugadzirwa kwealuminium anode. Chinangwa chayo ndechekubvisa kuparara kubva kune zvigadzirwa uye kuvandudza density, mechanical simba, magetsi conductivity uye kugadzikana kwemakemikari ezvigadzirwa. Munguva yekuverengera maitiro, iyo yekutanga kuumbwa uye kurongeka kwemaitiro epetroleum coke zvachinja, uye zvemuviri uye zvemakemikari zvimiro zvezvakagadzirwa zvakagadziridzwa zvakanyanya mushure mekuverengerwa.
Ichi chakakosha chigadzirwa chivakwa chinogona kusangana neindasitiri yemakemikari zvimwe zvinodiwa, kuitira kuti mamwe maindasitiri emaindasitiri ashandise zvakare. Mukuita calcination, iyo yakakwana yecalcination degree uye pertinence ye calcination process inokanganisa kubuda uye kurongeka kwepetroleum coke. Naizvozvo, zvakakosha zvikuru kudzidza tekinoroji yekuverengera tembiricha yepetroleum coke.
Kuongororwa kwehunyanzvi kwe calcined petroleum coke pakupisa kwakanyanya
Kubatanidza nekutengeserana kwemakemikari yenyika yedu kune calcine inosvika kune zvakasiyana zvinodiwa zvemhando, chengetedzo, chiyero chekugadzira uye zvichingodaro zvepetroleum coke chigadzirwa, ikozvino yakajairika tembiricha yekupisa calcine nzira dzenyika yedu ndeidzi: rotary kiln, coke oveni, tangi yevira, etc. Nheyo, hunhu, kushanda uye zviratidzo zvehupfumi zvehuwandu hwekuverengera hutekinoroji hunoenderana nehunyanzvi hwekugadzira.
(1) Rotary kiln calcining tekinoroji
1. Nheyo yekuongorora: Rotary kiln tekinoroji yakasanganiswa neyakakosha yemuviri chimiro chebhoni inotenderera inogona kuwana inoshanda kupisa kurapwa kweiyo yakasimba petroleum coke. Iyo musimboti weiyo rotary kiln tekinoroji ndeyekuvimba nekukwira kwekushisa kwekunze mukuita kwepetroleum coke calcination uye chiitiko chemakemikari mukati mekutenderera nekukurumidza, kuitira kuti ikurumidze kupisa kwepetroleum coke uye kugadzira petroleum coke inogadzirwa nepamusoro-tembiricha calcination.
2. Rotary kiln tekinoroji inonyanya kuve neanotevera maitiro:
1) Preheating: nekutenderera zvishoma nezvishoma silinda uye kuwedzera zvimwe zvinhu zvinopisa kuita kuti mukati petroleum coke isvike painopisa uye kupisa zvishoma nezvishoma;
2) Calcination: yekunze kukurumidza kwecylinder kutenderera, ichiwedzera tembiricha yecalcination, iyo yemukati petroleum coking kemikari reaction yakawedzera;
3) Kutonhodza: Kudzora kwepetroleum coke mushure mekupisa kwemvura kunoburitsa petroleum coke zvine hunyanzvi hwepamusoro.
3, zvakanakira uye zvakaipira uye ongororo inoshanda: yakasanganiswa neyakakura-yakakura kugadzirwa kwemaindasitiri, kiln inotenderera ine hunhu hwekushanda kuri nyore, kuburitsa kukuru, kudhura kwakaderera, kugadzirisa kuri nyore, nezvimwewo, inogona kushanda nemabhizinesi kwemakore makumi maviri kusvika makumi matatu, inokodzera kwakasiyana kabhoni petroleum coke kushandiswa. Panguva imwecheteyo, kiln inotenderera pachayo inoshandisa kutenderera uye makemikari maitiro emisimboti yezvinhu zvinopisa zvemukati kuchengetedza mutengo wezvinhu zvinopisa. Nekudaro, kana petroleum coke ichitenderera mucylinder axis, tembiricha yakakwira iri nyore kukonzeresa kupfeka uye kudonha kubva kune refractory, zvichikonzera kusagadzikana kwemhando yezvigadzirwa zvecalcined, pakati peiyo kugadzirwa kwepamusoro-soro kunongova 10%.
Naizvozvo, zvakasanganiswa nehunhu hwehuni inotenderera, mabhizinesi anofanirwa kuita kwakanangwa kurapwa kwezvivakwa zvekuvakisa uye maitiro panguva yekushanda, kuitira kuti asangane nezvinodiwa zvekuvandudza kugadzirwa kwemaindasitiri, kusimbisa calcination kusimba uye kuwedzera kunaka kwechigadzirwa kusvika pazvinobvira.
(2) Coke oven calcination tekinoroji
1. Nheyo yekuongorora: Coke oven calcination calcines iyo coke yakanyatsogadziriswa kuburikidza nepamusoro tembiricha calcination muchoto wakagadzirwa nezvidhinha zvidhinha zvine moto usingadzivirirwe, uye iyo coke inogadzirwa inogadzika uye inobatwa kugadzira zvigadzirwa zvakanaka zvinodiwa neindasitiri kugadzira coke. Mukuita uku, pane zvakaomesesa zvinodikanwa pakubata kwecoke mbishi uye tembiricha uye nguva yecalcination yecoke.
2, zvakanakira uye zvakaipira uye ongororo inoshanda: kana ichienzaniswa neinotenderera kiln tekinoroji, coke oven ine kugadzirwa kwepamusoro uye hunhu hwakanyanya. Iyo inosarudza kutarisana neyakasiyana-siyana yezvigadzirwa, inogona kuwana otomatiki kutonga mukushandiswa, inogona kuburitsa yakakwira mwero weyakapedzwa coke yemabhizinesi. Panguva imwecheteyo, kugadzirwa kwecoke oven kunotarisanawo nemamwe matambudziko ekuvaka, zvinodikanwa zvakanyanya zvekuvaka coke oven, kurongeka kwekushisa kwechoto, mutengo wepamusoro wekugadzirisa uchakanganisa chiyero chekupinda kwekugadzira coke oven.
Nekudaro, pakuvandudza tekinoroji yepetroleum coke calcination mune ramangwana, coke oven calcination inogona kuona basa rekuchengetedza simba uye kuderedza kubuda, uye inogona kuita mamwe mipiro mukuchengetedzwa kwezvakatipoteredza uye kushandiswa kwakazara kwesimba, coke oven calcination ine tarisiro yakakura yekusimudzira.
(3) tank calciner tekinoroji
1. Nheyo yekuongorora: Zvimiro zvikuru zve canne-mhando ye calcination furnace zvinosanganisira: tangi yekudyisa, nzira yemoto, kamuri yekutsinhanisa kupisa, kudyisa uye kuburitsa mudziyo, inotonhorera yekutenderera kwemvura mudziyo, nezvimwewo. Mukuita kwekupisa kwekushisa kwepamusoro, iyo petroleum coke yakawedzerwa kutangi inoziva kuenderera kwemukati kabhoni zvinhu kuburikidza neyakagadziriswa tembiricha yemukati kusvika pakupedza tembiricha. Iyo yakajairwa calcination tangi inogona kukamurwa kuita downflow calcination uye counterflow calcination zvinoenderana nedhigirii uye kutungamira kwekubuda kwehutsi.
2, mukana uye wakashata kuongororwa uye ongororo inoshanda: canner type calcination furnace inoshandiswa zvakanyanya munyika yedu, ndiyo musimboti maindasitiri nzira yenyika yedu kabhoni indasitiri, kuburikidza neakakosha kurapwa kwepetroleum coke inogona kusangana nekupisa zvakakwana, zvisina kunanga kudziyisa zvinodiwa, uye zvemukati zvinogona kudzivirira kubatwa nemhepo, kuderedza chiyero chekurasikirwa kweokisijeni, kuvandudza kubuda uye mhando yezvigadzirwa zvakapedzwa. Nekudaro, kana uchitora iyo canister calciner tekinoroji, kune akawanda manyore ekushandisa maitiro, ayo anowedzera njodzi yekuchengetedza. Panguva imwecheteyo, tangi calciner pachayo ine zvakawanda zvegomba zvinodiwa, izvo zvinokonzera kuoma kwekugadzirisa.
Mune ramangwana, mabhizinesi anogona kuenderera mberi nekudzidza tekinoroji yecanister calcination kubva pahuwandu hwekubuda, kuferefetwa kwenjodzi uye zvimwe zvinhu, kuitira kuti uwane chinangwa chekuwedzera kugadzirwa kwepetroleum coke yakanyanya tembiricha calcination.
Kupfupisa, tembiricha yepamusoro yepetroleum coke calcination ine simba guru paindasitiri yemakemikari uye indasitiri yealuminium yenyika yedu. Mabhizinesi anogona kusarudza yakakodzera yepamusoro-tembiricha calcination tekinoroji zvinoenderana nezvavo maindasitiri zvavanoda, uye pakupedzisira vaona kudzikiswa kwemutengo uye kuwedzera kwehunyanzvi kwemabhizinesi.
