Njengempahla ebalulekile yemboni yamakhemikhali yesimanje, inqubo yokubala izinga lokushisa eliphezulu kwe-petroleum coke inomthelela obalulekile kwikhwalithi kanye nesivuno se-petroleum coke. Kuleli phepha, ubuchwepheshe bokubala ukushisa okuphezulu kwe-petroleum coke kuxoxwa ngokuhambisana nokubaluleka kokukhiqiza. Okwereferensi yamabhizinisi.
Ukubaluleka kokukhiqizwa kwe-petroleum coke ngokubala izinga lokushisa eliphezulu
Ukubalwa kwe-petroleum coke kungenye yezinqubo eziyinhloko ekukhiqizeni i-anode ye-aluminium. Inhloso yawo ukususa ama-volatiles ezintweni ezingavuthiwe futhi kuthuthukiswe ukuminyana, amandla emishini, ukuqhutshwa kukagesi kanye nokuzinza kwamakhemikhali ezinto ezingavuthiwe. Phakathi nenqubo yokubala, ukwakheka okuyisisekelo kanye nesakhiwo senhlangano ye-petroleum coke kushintshile, futhi izakhiwo ezingokomzimba nezamakhemikhali zezinto zokusetshenziswa ziye zathuthukiswa kakhulu ngemva kokubala.
Lesi sakhiwo somkhiqizo esikhethekile singahlangabezana nezidingo ezengeziwe zemboni yamakhemikhali, ukuze amanye amabhizinisi ezimboni aphinde asebenzise. Enqubweni yokubala, ukunemba kwe-calcination degree kanye nokufaneleka kwenqubo yokubala kuzothinta ukukhishwa nokunemba kwe-petroleum coke. Ngakho-ke, kubaluleke kakhulu ukufunda ubuchwepheshe bokubala izinga lokushisa eliphezulu kwe-petroleum coke.
Ukuhlaziywa kobuchwepheshe be-calcined petroleum coke ekushiseni okuphezulu
Ukuhlanganiswa nokuhweba ngamakhemikhali kwezwe lethu kuya ku-calcine kufinyelela ezidingweni ezahlukahlukene zekhwalithi, ukuphepha, izinga lokukhiqiza nokunye komkhiqizo we-petroleum coke, izindlela zamanje ezijwayelekile zokushisa eziphakeme zezwe lethu yilezi: i-rotary kiln, i-oven coke, isithando somlilo sethangi. , njll. Umgomo, izici, ukusebenza kanye nezinkomba zezomnotho zobuchwepheshe obuningana bokubala ziyaqhathaniswa ukuze kunikezwe ireferensi yokukhiqizwa kwebhizinisi.
(1) Ubuchwepheshe be-Rotary kiln calcining
1. Ukuhlaziywa kwesimiso: Ubuchwepheshe be-rotary kiln obuhlanganiswe nesakhiwo esikhethekile somzimba we-rotary kiln bungafinyelela ukwelashwa okuphumelelayo kokushisa kwe-coke eqinile ye-petroleum. Umgomo wobuchwepheshe be-rotary kiln ukuthembela ekukhuphukeni kwezinga lokushisa kwangaphandle ohlelweni lokubala kwe-petroleum coke kanye nesenzo samakhemikhali ngaphakathi kwejubane lokujikeleza, ukuze kusheshiswe izinga lokushiswa kwe-petroleum coke nokwenza i-petroleum coke ekhiqizwa izinga lokushisa eliphezulu. calcination.
2. Ubuchwepheshe be-rotary kiln ikakhulukazi bunalezi zinqubo ezilandelayo:
I-1) Ukushisa: ngokuzungeza kancane isilinda bese wengeza izinto ezithile ezivuthayo ukuze i-coke yangaphakathi ye-petroleum ifinyelele endaweni yokuthungela futhi ishise kancane;
2) Ukubala: ukusheshisa kwangaphandle kokujikeleza kwe-cylinder, ngenkathi kwandisa izinga lokushisa lokubala, ukusabela kwamakhemikhali angaphakathi kwe-petroleum coking kwaqina;
3) Ukupholisa: Ukujiya kwe-petroleum coke ngemva kokushibilika kwamanzi kukhiqiza i-petroleum coke enembayo ephezulu.
I-3, izinzuzo nezinkinga kanye nokuhlaziywa okusebenzayo: kuhlanganiswe nokukhiqizwa kwezimboni ezinkulu, i-rotary kiln inezici zokusebenza okulula, okukhiphayo okukhulu, izindleko eziphansi, ukugcinwa okulula, njll., ingasebenza ngempumelelo emabhizinisini iminyaka engu-20 kuya kwengu-30, ilungele ukusetshenziswa okuhlukahlukene kwe-carbon petroleum coke. Ngesikhathi esifanayo, i-rotary kiln ngokwayo isebenzisa isimiso sokujikeleza nokusabela kwamakhemikhali wezinto ezivuthayo zangaphakathi ukuze wonge izindleko zezinto ezivuthayo. Kodwa-ke, lapho i-petroleum coke ijikeleza ku-cylinder axis, izinga lokushisa eliphezulu kulula ukubangela ukuguga nokuwa kwe-refractory, okuholela kukhwalithi engazinzile yemikhiqizo e-calcined, phakathi kwayo ukukhiqizwa okunemba okuphezulu cishe ku-10% kuphela. .
Ngakho-ke, kuhlanganiswe nezici ze-rotary kiln, amabhizinisi adinga ukwenza ukwelashwa okuhlosiwe kwezinto zokwakha eziko kanye nezinqubo ngesikhathi sokusebenza, ukuze kuhlangatshezwane nezidingo zokuthuthukisa ukusebenza kahle kokukhiqizwa kwezimboni, ukuqinisa amandla okubala kanye nokuthuthukisa ukunemba komkhiqizo ngangokunokwenzeka.
(2) Ubuchwepheshe be-coke oven calcination
1. Ukuhlaziywa kwesimiso: I-coke oven calcination ibala i-coke eye yaphathwa ngokukhethekile ngesithando sokushisa esishisayo esenziwe ngezitini ezikwazi ukumelana nomlilo, futhi i-coke ekhiqiziwe iyagaywa futhi iphathwa ukuze yenze imikhiqizo emihle edingwa imboni ukuze ikhiqize i-coke. . Kule nqubo, kunezidingo eziqinile kakhulu ekuqoqweni kwe-coke eluhlaza kanye nezinga lokushisa kanye nesikhathi sokubala kwe-coke.
2, izinzuzo nezinkinga kanye nokuhlaziywa okusebenzayo: uma kuqhathaniswa nobuchwepheshe be-rotary kiln, i-oven ye-coke inokukhiqiza okuphezulu kanye nezici zokunemba okuphezulu. Ikhetha ukubhekana nezinhlobonhlobo zezithako, ingafinyelela ukulawula okuzenzakalelayo ekusetshenzisweni, ingakhiqiza izinga eliphezulu le-coke eqediwe yamabhizinisi. Ngesikhathi esifanayo, ukukhiqizwa kwe-coke oven nakho kubhekene nezinkinga ezithile zokwakha, izidingo eziphakeme zokwakhiwa kwe-oven coke, ukunemba okuphezulu kokulawulwa kwezinga lokushisa kwesithando somlilo, izindleko eziphezulu zokulondoloza zizothinta izinga lokungena kokufakwayo kokukhiqizwa kwe-coke oven.
Kodwa-ke, ukuze kuthuthukiswe ubuchwepheshe be-petroleum coke calcination esikhathini esizayo, ukubalwa kwe-coke kuhhavini kungakwazi ukubona indima yokonga amandla kanye nokunciphisa ukungcola, futhi kungenza iminikelo ethile ekuvikelweni kwemvelo kanye nokusetshenziswa okuphelele kwamandla, ukubalwa kwe-coke oven kunethuba elibanzi lentuthuko. .
(3) ubuchwepheshe be-tank calciner
1. Ukuhlaziywa kwezimiso: Izakhiwo eziyinhloko zesithando somlilo sohlobo lukanezi zihlanganisa: ithange lokuphakela, indawo yomlilo, igumbi lokushintshanisa ukushisa, idivayisi yokuphakela nokukhipha, idivayisi yokupholisa amanzi, njll. Enqubweni yokubala izinga lokushisa eliphezulu, i-petroleum coke yengeziwe. ethangini ibona ukusabela okuqhubekayo kwe-carbon material yangaphakathi ngokusebenzisa impahla yangaphakathi engaguquki, ukuze kuqedelwe ukubalwa kwezinga lokushisa eliphezulu. Ithangi lokubala elivamile lingahlukaniswa libe ukubala kokugeleza kokwehla kanye nokubala kokugeleza kwe-counterflow ngokuya ngezinga kanye nesiqondiso sokuphuma kwentuthu.
I-2, ukuhlaziya okuhle nokubi kanye nokuhlaziywa okusebenzayo: isithando somlilo sohlobo lwe-canner sisetshenziswa kabanzi ezweni lethu, iyindlela eyinhloko yezimboni zezwe lethu imboni ye-carbon, ngokusebenzisa ukwelashwa okukhethekile kwe-petroleum coke ingahlangabezana nokushisa ngokugcwele, izidingo zokushisa ezingaqondile, futhi ingaphakathi lingagwema ukuthintana komoya, linciphise izinga lokulahlekelwa umoya-mpilo, lithuthukise ukukhishwa kanye nekhwalithi yemikhiqizo eqediwe. Kodwa-ke, lapho usebenzisa ubuchwepheshe be-canister calciner, kunezinqubo eziningi zokusebenza ezenziwa ngesandla, okwandisa ubungozi bokuphepha. Ngesikhathi esifanayo, i-tank calciner ngokwayo inezidingo eziningi zembobo, okubangela ubunzima bokugcinwa.
Ngokuzayo, amabhizinisi angaqhubeka nokutadisha ubuchwepheshe bokubala i-canister kusuka enanini elikhiphayo, uphenyo lwengozi yephutha nezinye izici, ukuze kuzuzwe inhloso yokwandisa ukukhiqizwa kwe-petroleum coke yokubala izinga lokushisa eliphezulu.
Ukufingqa, izinga lokushisa eliphezulu le-petroleum coke calcination linethonya elikhulu embonini yamakhemikhali kanye nemboni ye-aluminium yezwe lethu. Amabhizinisi angakhetha ubuchwepheshe bokubala obusezingeni eliphezulu obufanele ngokwezidingo zabo zezimboni, futhi ekugcineni abone ukuncishiswa kwezindleko kanye nokwenyuka kokusebenza kahle kwamabhizinisi.
