Ndi chitukuko chachangu cha makampani electrolytic zotayidwa, zotayidwa prebaking anode makampani wakhala latsopano ndalama hotspot, kupanga prebaking anode likuchulukirachulukira, mafuta coke ndi waukulu zopangira prebaking anode, ndi zolozera adzakhala ndi zotsatira zina pa khalidwe la mankhwala.
sulfure wamkati
Kuchuluka kwa sulfure mu petroleum coke makamaka kumadalira mtundu wamafuta amafuta. Nthawi zambiri, mafuta a sulfure akakhala ochepa, kugwiritsa ntchito anode kumachepa ndi kuchuluka kwa sulfure, chifukwa sulfure imawonjezera kuchuluka kwa phula ndipo imachepetsa kulimba kwa phula. Pa nthawi yomweyo, sulfure komanso pamodzi ndi zitsulo zosafunika, kuchepetsa Catalysis ndi zitsulo zonyansa kupondereza mpweya woipa reactivity ndi mpweya reactivity wa anode mpweya. Komabe, ngati sulfure okhutira ndi okwera kwambiri, izo kuonjezera matenthedwe Chimaona a carbon anode, ndipo chifukwa sulfure makamaka anasandulika mu gawo mpweya mu mawonekedwe a oxides pa ndondomeko electrolysis, izo kwambiri zimakhudza electrolysis chilengedwe, ndi kuteteza chilengedwe kuthamanga adzakhala wamkulu. Komanso, sulfuration akhoza kupangidwa pa anode ndodo Chitsulo filimu, kuwonjezera voteji dontho. Pamene mafuta akutuluka m'dziko langa akuchulukirachulukira komanso njira zopangira mafuta zikuyenda bwino, chizolowezi cha mafuta otsika a petroleum coke sichingapeweke. Kuti azolowere kusintha kwa zipangizo, prebaked anode opanga ndi electrolytic zotayidwa makampani achita chiwerengero chachikulu cha masinthidwe luso ndi zopambana luso. Kuchokera ku China zoweta prebaked anode Malinga ndi kafukufuku wa mabizinesi kupanga, petroleum coke ndi sulfure zili pafupifupi 3% akhoza zambiri mwachindunji calcined.
Tsatirani zinthu
Kufufuza zinthu mu petroleum coke makamaka monga Fe, Ca, V, Na, Si, Ni, P, Al, Pb, etc. Zinthu zina zotsatiridwa zimabweretsedwa kuchokera ku mafuta obiriwira, monga S, V, ndi zina zotero. Zitsulo zina za alkali ndi zitsulo zamchere zamchere zidzabweretsedwanso, ndipo phulusa lina lidzawonjezedwa panthawi yoyendetsa ndi kusunga, monga Si, Fe, Ca, ndi zina zotero. Ca, V, Na, Ni ndi zinthu zina ali ndi mphamvu yothandiza kwambiri pa anodic makutidwe ndi okosijeni anachita, amene amalimbikitsa kusankha makutidwe ndi okosijeni wa anode, kuchititsa anode kusiya slag ndi midadada, ndi kuonjezera kumwa kwambiri anode; Si ndi Fe makamaka zimakhudza khalidwe la aluminiyamu pulayimale, ndi Si zomwe zikuwonjezeka Zidzawonjezera kuuma kwa aluminiyamu, kuchepetsa mphamvu yamagetsi, ndi kuwonjezeka kwa Fe zomwe zili ndi chikoka chachikulu pa pulasitiki ndi kukana kwa dzimbiri kwa aluminiyamu alloy. Kuphatikizidwa ndi zofunikira zenizeni zamabizinesi, zomwe zili muzinthu zotsatizana monga Fe, Ca, V, Na, Si, ndi Ni mu petroleum coke ziyenera kukhala zochepa.
Zinthu zosasinthika
Kutentha kwakukulu kwa petroleum coke kumasonyeza kuti gawo losaphika limatengedwa kwambiri. Kuchulukirachulukira kopitilira muyeso kungakhudze kachulukidwe wowona wa calcined coke ndikuchepetsa zokolola zenizeni za coke calcined, koma kuchuluka kosinthika koyenera kumathandizira kuwerengetsa mafuta a petroleum coke. Pambuyo mafuta coke calcined pa kutentha, kosakhazikika okhutira amachepetsa. Popeza ogwiritsa ntchito osiyanasiyana ali ndi ziyembekezo zosiyanasiyana za zinthu zosasunthika, kuphatikiza ndi zosowa zenizeni za opanga ndi ogwiritsa ntchito, zimanenedwa kuti zomwe zikusokonekera siziyenera kupitirira 10% -12%.
Phulusa
Zowonongeka zamchere zomwe sizingayaka (kufufuza zinthu) zomwe zimatsalira pambuyo pa gawo loyaka moto la petroleum coke zimatenthedwa kwathunthu ndi kutentha kwambiri kwa madigiri 850 ndipo kufalikira kwa mpweya kumatchedwa phulusa. Cholinga cha kuyeza phulusa ndikuzindikira zomwe zili muzowonongeka zamchere (kufufuza zinthu) Mochuluka bwanji, kuti muwunikire mtundu wa petroleum coke. Kuwongolera zomwe zili phulusa zidzalamuliranso zinthu zotsatizana. Phulusa lambiri lidzakhudza mtundu wa anode wokha komanso aluminiyamu yoyamba. Kuphatikizidwa ndi zosowa zenizeni za ogwiritsa ntchito komanso momwe amapangira mabizinesi, zimanenedwa kuti phulusa siliyenera kupitirira 0.3% -0.5%.
Chinyezi
Magwero akuluakulu a madzi mu mafuta a petroleum coke: Choyamba, pamene nsanja ya coke imatulutsidwa, mafuta a petroleum coke amatulutsidwa ku dziwe la coke pansi pa kudula kwa hydraulic; chachiwiri, poyang'ana chitetezo, coke ikatulutsidwa, mafuta a petroleum coke omwe sanazimitsidwe kwathunthu amayenera kupopera kuti aziziritsa Chachitatu, mafuta a petroleum coke amayikidwa panja m'madziwe a coke ndi mabwalo osungiramo zinthu, ndipo chinyezi chake chidzakhudzidwanso ndi chilengedwe; chachinayi, petroleum coke ili ndi mapangidwe osiyanasiyana komanso kuthekera kosiyanasiyana kosunga chinyezi.
Coke content
Kukula kwa tinthu ta petroleum coke kumakhudza kwambiri zokolola zenizeni, kugwiritsa ntchito mphamvu ndi coke calcined. Mafuta a coke okhala ndi ufa wochuluka wa coke amakhala ndi kutaya kwambiri kwa carbon panthawi ya calcination. Kuwombera ndi zinthu zina kungayambitse mosavuta mavuto monga kusweka koyambirira kwa ng'anjo yamoto, kuwotcha mopitirira muyeso, kutsekeka kwa valve yotulutsa, kumasuka komanso kosavuta kupukuta coke calcined, ndikukhudza moyo wa calciner. Pa nthawi yomweyo, kachulukidwe weniweni, kachulukidwe wapampopi, porosity, ndi mphamvu ya calcined coke , Resistivity ndi ntchito ya okosijeni imakhala ndi chikoka chachikulu. Kutengera momwe zinthu ziliri pakupanga mafuta amafuta amafuta, kuchuluka kwa ufa wa coke (5mm) kumayendetsedwa mkati mwa 30% -50%.
Chotsani zinthu za coke
Shot coke, yomwe imadziwikanso kuti spherical coke kapena shot coke, ndi yolimba, yowundana komanso yopanda porous, ndipo imakhalapo ngati mikwingwirima yosungunuka. Pamwamba pa kuwombera coke ndi yosalala, ndipo mawonekedwe amkati sakugwirizana ndi kunja. Chifukwa cha kusowa kwa ma pores pamtunda, pokanda ndi binder phula phula, zimakhala zovuta kuti chomangiracho chilowe mkati mwa coke, zomwe zimapangitsa kuti zisawonongeke komanso zimakhala zovuta kusokoneza mkati. Kuonjezera apo, coefficient yowonjezera kutentha kwa coke coke ndi yokwera, zomwe zingayambitse mosavuta ming'alu ya kutentha pamene anode yaphikidwa. Mafuta a petroleum coke omwe amagwiritsidwa ntchito mu anode yophikidwa kale sayenera kukhala ndi mfuti ya coke.
