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 tekinoroji 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 chekugadzirwa uye zvichingodaro zvepetroleum coke chigadzirwa, ikozvino yakajairika tembiricha yekupisa calcine nzira dzenyika yedu ndeidzi: rotary kiln, coke oveni, tank choto. , etc. Nheyo, maitiro, kushanda uye zviratidzo zvehupfumi zvematekinoroji akawanda ecalcination anofananidzwa kuitira kupa chirevo chekugadzirwa kwebhizinesi.
(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. Nheyo ye 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 nyore, kuburitsa kukuru, kudhura kwakaderera, kugadzirisa kuri nyore, nezvimwewo, inogona kushanda nemabhizinesi kwemakore makumi maviri kusvika makumi matatu, yakakodzera kushandiswa kwakasiyana kwekabhoni petroleum coke. Panguva imwecheteyo, kiln inotenderera pachayo inoshandisa kutenderera uye makemikari maitiro emisimboti yezvinhu zvinopisa zvemukati kuchengetedza mutengo wezvinhu zvinopisa. Nekudaro, kana iyo petroleum coke ichitenderera mucylinder axis, tembiricha yakakwira iri nyore kukonzeresa kupfeka uye kudonha kubva kune refractory, zvichikonzera kusagadzikana kwemhando yezvigadzirwa zve calcined, pakati peiyo kugadzirwa kwepamusoro-soro kunenge 10% chete. .
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. Ongororo yemisimboti: Coke oven calcination calcines iyo coke yakanyatso kurapwa kuburikidza neyakakura tembiricha yekuverengera muchoto yakagadzirwa nezvidhinha neyakakura moto inodzivirira, uye iyo coke inogadzirwa inogadzika uye inobatwa kuti igadzire 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 tekinoroji 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. Ongororo yemisimboti: Zvimiro zvikuru zve canne-type calcination virace zvinosanganisira: tangi yekudyisa, nzira yemoto, kamuri yekutsinhanisa kupisa, kudyisa nekuburitsa mudziyo, inotonhorera yekutenderera kwemvura mudziyo, nezvimwe. Mukuita kwekupisa kupisa kwepamusoro, petroleum coke yakawedzerwa. kune tangi inoona kuenderera kwekuita kwemukati kabhoni zvinhu kuburikidza nemukati yakagadziriswa zvinhu, kuitira kuti ipedze iyo yakanyanya tembiricha calcination. 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 yakakosha maindasitiri nzira yenyika yedu kabhoni indasitiri, kuburikidza nekurapa kwakakosha kwepetroleum coke inogona kusangana nekupisa zvizere, zvisina kunanga kupisa zvinodiwa, uye. iyo yemukati inogona kudzivirira kusangana nemhepo, kuderedza kurasikirwa kweokisijeni, kunatsiridza kubuda uye kunaka kwezvakapedzwa zvigadzirwa. 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.
