Njengezinto ezibalulekile zokusetshenziswa embonini yamakhemikhali yanamuhla, inqubo yokubala amazinga okushisa aphezulu ye-petroleum coke inomthelela obalulekile ekhwalithini nasekuvuneni kwe-petroleum coke. Kuleli phepha, ubuchwepheshe bokubala amazinga okushisa aphezulu be-petroleum coke buxoxwa buhambisana nokubaluleka kwayo kokukhiqiza. Ukuze kubhekwe amabhizinisi.
Ukubaluleka kokukhiqizwa kwe-petroleum coke nge-calcination yokushisa okuphezulu
Ukwenziwa kwe-calcination ye-petroleum coke kungenye yezinqubo eziyinhloko ekukhiqizweni kwe-aluminium anode. Inhloso yayo ukususa izinto eziguquguqukayo ezintweni zokusetshenziswa nokuthuthukisa ubuningi, amandla okusebenza, ukuqhuba kukagesi kanye nokuzinza kwamakhemikhali kwezinto zokusetshenziswa. Ngesikhathi senqubo yokwenziwa kwe-calcination, ukwakheka kwezinto eziyisisekelo kanye nesakhiwo sokuhlela se-petroleum coke kushintshile, futhi izakhiwo zomzimba nezamakhemikhali zezinto zokusetshenziswa zithuthukisiwe kakhulu ngemva kokwenziwa kwe-calcination.
Lo mkhiqizo okhethekile ungahlangabezana nezidingo ezengeziwe embonini yamakhemikhali, ukuze amanye amabhizinisi ezimboni aphinde asebenzise. Enkambisweni yokubala, ukuphelela kwezinga lokubala kanye nokufaneleka kwenqubo yokubala kuzothinta umkhiqizo kanye nokunemba kwe-petroleum coke. Ngakho-ke, kubaluleke kakhulu ukutadisha ubuchwepheshe bokubala ukushisa okuphezulu kwe-petroleum coke.
Ukuhlaziywa kobuchwepheshe kwe-coke kaphethiloli ene-calcined ekushiseni okuphezulu
Uma kuhlanganiswa nokuhweba ngamakhemikhali kwezwe lethu nge-calcine kufinyelela ezidingweni ezahlukahlukene zekhwalithi, ukuphepha, izinga lokukhiqiza nokunye komkhiqizo we-petroleum coke, izindlela ze-calcine ezivamile zamanje zezwe lethu yilezi: i-rotary kiln, i-coke oven, i-tank furnace, njll. Isimiso, izici, ukusebenza kanye nezinkomba zomnotho zobuchwepheshe obuningana be-calcination ziqhathaniswa ukuze kunikezwe inkomba yokukhiqizwa kwebhizinisi.
(1) Ubuchwepheshe bokwenza i-calcining kuhhavini ojikelezayo
1. Ukuhlaziywa Okuyisisekelo: Ubuchwepheshe be-rotary kiln obuhlanganiswe nesakhiwo esikhethekile somzimba we-rotary kiln bungafeza ukwelashwa okusebenzayo kokushisa kwe-coke kaphethiloli eqinile. Umgomo wobuchwepheshe be-rotary kiln ukuthembela ekukhuphukeni kwezinga lokushisa langaphandle enkambisweni ye-calcination ye-coke kaphethiloli kanye nesenzo samakhemikhali ngaphakathi kwesivinini sokujikeleza, ukuze kusheshiswe izinga lokusha kwe-coke kaphethiloli futhi kwenziwe i-coke kaphethiloli ekhiqizwe yi-calcination yokushisa okuphezulu.
2. Ubuchwepheshe be-rotary kiln bunezinqubo ezilandelayo:
1) Ukushisa: ngokujikeleza kancane isilinda bese ufaka izinto ezithile ezivuthayo ukuze wenze i-petroleum coke yangaphakathi ifinyelele endaweni yokushisa futhi ishise kancane;
2) Ukushisa: ukusheshisa kwangaphandle kokujikeleza kwesilinda, ngenkathi kukhulisa izinga lokushisa lokushisa, ukusabela kwamakhemikhali okupheka kwangaphakathi kwe-petroleum kwanda;
3) Ukupholisa: Ukujiya kwe-petroleum coke ngemva kokuguquguquka kwamanzi kukhiqiza i-petroleum coke ngokunemba okuphezulu.
3, izinzuzo kanye nokungalungi kanye nokuhlaziywa okusebenzayo: kuhlanganiswe nokukhiqizwa kwezimboni okukhulu, i-rotary kiln inezimpawu zokusebenza okulula, umkhiqizo omkhulu, izindleko eziphansi, ukulungiswa okulula, njll., ingasebenza ngempumelelo emabhizinisini iminyaka engama-20 kuya kwengama-30, ifanele ukusetshenziswa kwe-carbon petroleum coke ehlukahlukene. Ngesikhathi esifanayo, i-rotary kiln ngokwayo isebenzisa umgomo wokujikeleza kanye nokusabela kwamakhemikhali wezinto zokushisa zangaphakathi ukuze yonge izindleko zezinto zokushisa. Kodwa-ke, lapho i-petroleum coke ijikeleza ku-axis yesilinda, izinga lokushisa eliphezulu kulula ukubangela ukuguguleka nokuwa kwe-refractory, okuholela ekhwalithini engazinzile yemikhiqizo ene-calcium, phakathi kwayo ukukhiqizwa okunembile okuphezulu kungama-10% kuphela.
Ngakho-ke, kuhlanganiswe nezici ze-rotary kiln, amabhizinisi adinga ukwenza ukuphathwa okuqondiwe kwezinto zokwakha ze-furnace kanye nezinqubo ngesikhathi sokusebenza, ukuze kuhlangatshezwane nezidingo zokuthuthukisa ukusebenza kahle kwemikhiqizo yezimboni, ukuqinisa ukuqina kwe-calcination kanye nokuthuthukisa ukunemba komkhiqizo ngangokunokwenzeka.
(2) Ubuchwepheshe bokubala i-oven ye-coke
1. Ukuhlaziywa Okuyisisekelo: I-calcination ye-oven ye-coke i-calcines i-coke ephathwe ngokukhethekile ngesithando sokushisa esiphezulu esenziwe ngamabhulokhi ezitini anokumelana nomlilo okuphezulu, kanti i-coke ekhiqizwayo iyagaywa futhi iphathwe ukuze yakhe imikhiqizo emihle edingekayo embonini ukukhiqiza i-coke. Kule nqubo, kunezidingo eziqinile kakhulu ekuhlanganisweni kwe-coke eluhlaza kanye nokushisa nesikhathi sokugaya i-coke.
2, izinzuzo kanye nokungalungi kanye nokuhlaziywa okusebenzayo: uma kuqhathaniswa nobuchwepheshe be-rotary kiln, i-coke oven inomkhiqizo ophezulu kanye nezici zokunemba okuphezulu. Ikhetha ukubhekana nezithako ezahlukahlukene, ingafinyelela ukulawula okuzenzakalelayo okusetshenziswayo, ingakhiqiza izinga eliphezulu le-coke eqediwe yamabhizinisi. Ngesikhathi esifanayo, ukukhiqizwa kwe-coke oven nakho kubhekene nezinkinga ezithile zokwakha, izidingo eziphezulu zokwakhiwa kwe-coke oven, ukunemba okuphezulu kokulawula izinga lokushisa kwesithando, izindleko eziphezulu zokulungisa zizothinta izinga lokungena kokufakwa kokukhiqiza kwe-coke oven.
Kodwa-ke, ukuze kuthuthukiswe ubuchwepheshe be-petroleum coke calcination esikhathini esizayo, i-coke oven calcination ingafeza indima yokonga amandla kanye nokunciphisa ukukhishwa komoya, futhi ingaba negalelo elithile ekuvikelweni kwemvelo nasekusetshenzisweni okuphelele kwamandla, i-coke oven calcination inethuba elibanzi lokuthuthukiswa.
(3) ubuchwepheshe be-calciner yethangi
1. Ukuhlaziywa Okuyisisekelo: Izakhiwo eziyinhloko zesithando somlilo se-calcination sohlobo lwe-canne zifaka: ithangi lokudla, indlela yomlilo, igumbi lokushintshanisa ukushisa, idivayisi yokondla nokukhipha, idivayisi yokujikeleza kwamanzi okupholisa, njll. Enkambisweni yokubala izinga lokushisa eliphezulu, i-petroleum coke engezwe ethangini ibona ukusabela okuqhubekayo kwezinto zangaphakathi zekhabhoni ngokusebenzisa izinto zangaphakathi eziqinile, ukuze kuqedwe ukubala izinga lokushisa eliphezulu. Ithangi elivamile lokubala lingahlukaniswa libe ukubala okuphansi kanye nokubala okuphambene nokugeleza ngokuya ngezinga kanye nesiqondiso sokukhishwa kwentuthu.
2, ukuhlaziywa kwezinzuzo nokungalungi kanye nokuhlaziywa okusebenzayo: isithando somlilo se-calcination sohlobo lwe-canner sisetshenziswa kabanzi ezweni lethu, siyindlela eyinhloko yezimboni embonini ye-carbon yezwe lethu, ngokuphathwa okukhethekile kwe-petroleum coke kungahlangabezana nokushisa ngokugcwele, izidingo zokushisa ezingaqondile, futhi ingaphakathi lingagwema ukuthintana nomoya, linciphise izinga lokulahlekelwa umoya-mpilo, lithuthukise umkhiqizo kanye nekhwalithi yemikhiqizo eqediwe. Kodwa-ke, lapho kusetshenziswa ubuchwepheshe be-calciner ye-canister, kunezinqubo eziningi zokusebenza ngesandla, okwandisa ingozi yokuphepha. Ngesikhathi esifanayo, i-calciner yethangi ngokwayo inezidingo eziningi zemigodi, okubangela ubunzima bokugcinwa.
Esikhathini esizayo, amabhizinisi angaqhubeka nokutadisha ubuchwepheshe be-calcination ye-canister kusukela enanini lokukhishwa, uphenyo lwengozi yamaphutha kanye nezinye izici, ukuze kufezwe injongo yokwandisa ukukhiqizwa kwe-calcination ye-petroleum coke enokushisa okuphezulu.
Ngamafuphi, izinga lokushisa eliphezulu le-petroleum coke calcination linethonya elikhulu embonini yamakhemikhali kanye nemboni ye-aluminium yezwe lethu. Amabhizinisi angakhetha ubuchwepheshe obufanele be-calcination obusezingeni eliphezulu ngokwezidingo zawo zezimboni, futhi ekugcineni aqaphele ukwehliswa kwezindleko kanye nokwenyuka kokusebenza kahle kwamabhizinisi.
