Kugadzirisa Maitiro Ezvinhu Zvisina Kugadzirwa zveVagadziri veCalcined Petroleum Coke Pakati Pekushomeka KweSulfur Ishoma
Zvichienderana nekuwedzera kushomeka kwe coke ine sarufa shoma (huwandu hwesarufa <1%, kunyanya sulfur coke yakaderera <0.5%) uye kukwikwidza kuri kuwedzera kubva kuzvinhu zve lithium battery anode uye anode dzakabikwa kare, zvivakwa zve calcination zvinofanirwa kuchinja nzira dzazvo dzezvinhu zvisina kugadzirwa kubva pakutsvaga sarufa shoma kuenda kune nzira yakarongeka yekubatana kwezvinhu zvakawanda, kushandiswa kwe cascading, kutsiva tekinoroji, uye kudzivirira njodzi. Pfungwa huru inogona kupfupikiswa munzira dzinotevera:
I. Kugadziriswa kweMagadzirirwo eZvinhu Zvisina Kugadzirwa: Kubva ku "All Low-Sulfur" kuenda ku "Kusanganiswa kweSainzi kwe Low-Sulfur + Medium-Sulfur"
Chinhu chinonyanya kurwadza nezve low-sulfur coke ndechekuti inodhura uye haiwanikwe. Kare, mafekitori e calcination aiwanzoshandisa zvakanyanya low-sulfur coke kuti ave nechokwadi chekuti sarufa inotevedzera zvinodiwa nezvigadzirwa. Zvisinei, munzvimbo yaisawanikwa zvakawanda uye mitengo yakakwira zvakanyanya (muna 2025, avhareji yemutengo we low-sulfur coke #1 yakawedzera gore negore neanopfuura 57% pane imwe nguva), nzira iyi haichashandi.
Nzira inoshanda ndeyekugadzira sisitimu ye "high-low sulfur blending". Ma anode akabikwa kare uye ma electrode e graphite ane simba rakati rekurerutsira huwandu hwe sarufa. Sulfur coke yepakati-pasi inogona kusanganiswa ne low-sulfur coke muzvikamu zvakati (semuenzaniso, low-sulfur: medium-sulfur = 4:6 kana 3:7) kuderedza zvakanyanya mitengo yezvinhu zvisina kugadzirwa uku ichizadzisa zvinodiwa ne sulfur yechigadzirwa. Chinokosha ndechekuvaka database yechinhu chega chega chine zvinhu zvisina kugadzirwa chinosanganisira sulfur content, volatile matter, true density, uye trace elements (V, Ni, Fe, nezvimwewo), uye kushandisa ma formulation models kuverenga nemazvo blending ratios kuti uve nechokwadi chekuti calcium physicochemical properties ye calcined coke yakamira.
Pamafekitori ekugadzira calcium, izvi zvinoreva kuti divi rekutenga rinofanira kuchengetedza panguva imwe chete manyuko ecoke yepakati nepakati (coke yepakati nepakati kubva kumafekitori emuno akazvimiririra inokwana 38% yehuwandu hwese hwezvinhu zviripo uye yakawanda), pane kuisa kumanikidzwa kwese kwekutenga pacoke yepasi nepakati.
II. Kusiyanisa Nzira Dzekupinza Zvinhu: Kuvhara Nzvimbo Dzinogara Dzakagadzikana uye Kuparadzira Njodzi Dzezvematongerwo Enyika
Coke ine sarufa shoma inoburitsa mafuta mudzimba inongopa 14% chete yemafuta ese anowanikwa mumafuta epetroleum coke (ayo ane sarufa <0.5% inongopa 4%) chete, nepo lithium battery anodes inototora 29% yemafuta ane sarufa shoma anoburitsa mafuta mudzimba uye ichiri kukura nekukurumidza. Mukana wezvinhu zvinowanikwa mudzimba haugone kuvharwa munguva pfupi. Nokudaro, kutenga coke ine sarufa shoma kunosara kuri chinhu chakakosha, asi zvirimwa hazvigone kuvimba nechinhu chimwe chete.
Zviito zvakananga zvinosanganisira:
- Kutsvaga mari kubva kunyika dzakasiyana-siyana: Kunze kwenzvimbo dzekare dzekuMiddle East neSoutheast Asia, tarisa pane dzimwe nzvimbo dzisiri dzechinyakare dzecoke dzine sarufa shoma dzakadai seRussia neAzerbaijan. Sainai zvibvumirano zvenguva refu kusvika pakati nepakati (gore 1-3) ne "mutengo wekuenzanisa + kugadzirisa kunofamba" kuti muwane mutengo wakaderera.
- Wedzerai zvinhu zvinotengeswa kunze kwenyika zvine sulfur coke yakawanda sechinotsiva: High-sulfur coke haishandiswi zvakanyanya muma anode akabikwa kare emumba nekuda kwezvinetso zvekubuda kweSO₂, asi ichiri nemisika muzvigadzirwa zvekabhoni isinganyanyi kubatwa nesulfur, silicon carbide, calcium carbide, nezvimwewo. Southeast Asia neMiddle East high-sulfur coke inopa zvakanakira pamutengo wakajeka. Mafekitori e calcination anogona kugadzira mitsetse ye calcination ye high-sulfur coke yakanangana nezvigadzirwa izvi zviri pasi.
- Shandisai nzira dzekuchengetedza mari yemberi nesarudzo: Dzivirirai 30%–50% yehuwandu hwezvinhu zvinotengeswa kunze kwenyika, uye shandisai nzira dzekudzivirira mari yekunze kuderedza njodzi mbiri dzekuchinja-chinja kwemitengo yekunze pamwe chete nekushanduka-shanduka kwemitengo.
III. Kutsiva Tekinoroji uye Kugadzirisa Fomura: Deredza Kuvimba neLow-Sulfur Coke paKunobva
Iyi ndiyo nzira ine kukosha kukuru kwenguva refu. Chinangwa chekushaikwa kwecoke ine sarufa shoma kuchinja kwechimiro chekudiwa kwemvura - lithium battery anodes uye high-end graphite electrodes zviri kukura nekukurumidza kupfuura kuwanikwa. Kana ma calcination plants akangogadzirisa dambudziko chete kudivi rekutenga, acharamba ari reactive. Anofanirawo kuita budiriro kudivi retekinoroji.
