Ndeipi muganho wepamusoro unobvumidzwa wekuti sarufa ipinde muchoto kuti ive nechokwadi chekuti anode yakanaka?

Kusanganisa Nheyo dzeChiyero chePetroleum Coke neZviri muSulfur Zvinosiyana:

Ndeipi Maximum Allowable Sulfur Limit yeKiln Feed kuti ive nechokwadi chekuti Anode Yakanaka?**

Mukugadzirwa kweanode dzakabikwa kare nearuminiyamu, muganho wepamusoro wesarufa unobvumirwa wekudya kwechoto unowanzova 3.0% kuti uve nechokwadi chekuti anode yakanaka. Muganho uyu unobva pane zvinotevera zvinokosha uye zvinhu zvehunyanzvi:

1. Kukanganisa Kuviri Kwemusanganiswa weSulfur Pakushanda kweAnode

• Mabhenefiti eSulfur Isina Zvishoma:
  Kana huwandu hwesarufa hwakaderera (semuenzaniso, ≤2.0%), kugadzikana kwekushisa kweanode uye kuramba kweoxidation zvinovandudzika, zvichideredza kuburitswa kwesulfur oxide (SOₓ) panguva yemagetsi uye zvinoderedza njodzi yekusvibiswa kwezvakatipoteredza. Pamusoro pezvo, low-sulfur coke inoderedza kutsemuka kweanode, kupararira, uye kushandiswa zvakanyanya uku ichiwedzera hupenyu hwebasa.
• Njodzi dzeSulfur Yakawanda:
  Kuwanda kwesarufa (semuenzaniso, >3.0%) kunowedzera zvakanyanya kusimba kweanode thermal, zvichikonzera kutsemuka nekupwanyika panguva yeelectrolysis, izvo zvinowedzera kushandiswa zvakanyanya. Uyezve, sarufa inogadzira sulfides (semuenzaniso, FeS) panguva yeelectrolysis, zvichiwedzera kuramba kubatana pakati peanode rod necarbon anode, zvichikwidza kudonha kwevoltage, uye zvichiwedzera kushandiswa kwesimba.

2. Nheyo dzeKusanganisa Chiyero: Kudzora Kuwanda kweSulfur muKirn Feed ≤3.0%

• Kusanganisa High- ne Low-Sulfur Coke:
  Coke ine sarufa yakawanda (semuenzaniso, 4.5% sarufa) inogona kusanganiswa necoke ine sarufa shoma (semuenzaniso, 1.2% sarufa) kuti ideredze zviri nani huwandu hwesarufa yecoke yakasanganiswa. Semuenzaniso, chiyero chekusanganisa che1:1 chinoburitsa huwandu hwesarufa yakasanganiswa ye2.85%, zvichisangana nemiganhu yekudya kwechoto. Kuti zviwedzere kuderedzwa, kugadzirisa chiyero (semuenzaniso, 1:2) kunoderedza huwandu hwesarufa kusvika 2.30%.
• Kuchengetera Kwakatsaurirwa uye Kubatanidza Zvakakodzera:
  Coke ine sarufa yakawanda neyakaderera inofanira kuchengetwa yoga kuti isasvibiswe. Panguva yekubatanidza, mabhaketi ekubata anoshandiswa kusanganisa zvinhu zvichienderana nehuwandu, zvichiita kuti pave nekusanganiswa kwakafanana vasati vapinda mu calciner uye kudzikamisa huwandu hwesarufa mukati menzvimbo dzakatarwa.
• Kugadzirisa Maitiro Ekuverenga Calcination:
  Kunyatso tarisa tembiricha ye calcination (kazhinji 1250–1350°C) uye nguva yakakwana yekunyikwa kwakakosha kuderedza marara anoshanduka uye kuvandudza kunaka kwe calcined coke. Kugadziriswa kwezviyero kunoita kuti calciner ishande zvakanaka.

3. Maitiro Eindasitiri Ekushandisa Zvikafu zveSulfur Zvakanyanya

• Ongororo dzeVagadziri veAnode Yakabikwa Mudzimba:
  Petroleum coke ine 3.0% sarufa inogona kucheneswa zvakananga pasina kuwedzera desulfurization, zvichiratidza kubvumirana kweindasitiri pakuenzanisa mhando yeanode uye kushanda kwayo pamutengo.
• Referensi yeMitemo Yepasi Pose:
  Indasitiri yekabhoni yealuminium inowanzoda huwandu hwesarufa ≤3.0% mupetroleum coke. Semuenzaniso, Grade 3B raw petroleum coke inotsanangura muganho wesarufa we3.0%, wakakodzera kugadzirwa kweanode yakabikwa kare.

4. Migumisiro Yekupfuura Miganhu yeSarufa

• Hunhu hweAnode Yakaora:
  Sarufa yakawandisa inowedzera kuputsika kwekupisa, zvichikonzera kutsemuka, kupwanyika, uye kushandiswa kwakanyanya panguva yekushandiswa kwemagetsi. Kuramba kweanode kwakakwira kunowedzera voltage yemasero uye kushandiswa kwesimba rearuminiyamu patani.
• Kusvibiswa Kwezvakatipoteredza Kwakanyanya:
  Kuwedzera kweSOₓ kuburitswa kwemhepo panguva yemagetsi kunokanganisa kunaka kwemhepo uye kunotyora mitemo yezvakatipoteredza.
• Kupfeka Zvishandiso Zvinokurumidza:
  Mafirimu esulfide (semuenzaniso, FeS) ari pamatanda anode anowedzera kuramba kwekubatana, zvichikurumidzisa kuora kwemidziyo uye zvinopfupikisa hupenyu hwebasa.
