Abstract
Description
本発明は製鋼メーカーなどで発生する電炉ダストに多く含まれる酸化鉄を高周波誘導加熱を用いて簡易にかつ低コストで還元鉄として再資源化する装置である．The present invention is an apparatus that recycles iron oxide contained in a lot of electric furnace dust generated by steelmakers as reduced iron easily and at low cost using high frequency induction heating.
製鋼メーカーなどで発生する電炉ダストの処理は現在、埋め立て処理もしくは、処理業者への委託によって行われている。The treatment of electric furnace dust generated by steel makers, etc., is currently carried out by landfill treatment or commissioned to a treatment company.
しかし、この電炉ダストには酸化鉄や亜鉛といった資源として再利用可能な成分が多く含まれている。これらを再資源化することでこれまで処理物として扱っていた電炉ダストの有価物化が可能である。そのため、電炉ダストの再資源化を簡易かつ安価に行う装置の発明が求められている。However, this electric furnace dust contains many reusable components such as iron oxide and zinc. By recycling these, it is possible to convert the electric furnace dust, which has been handled as processed materials, into valuable resources. For this reason, there is a need for an invention for an apparatus that simply and inexpensively recycles electric furnace dust.
本発明は鉄鋼メーカーなどから発生し、現在産業廃棄物として処理されている電炉ダストから還元鉄、亜鉛を取り出すことで、資源として再利用することを課題とする。This invention makes it a subject to recycle | reuse as resources by taking out reduced iron and zinc from the electric furnace dust which generate | occur | produces from the steelmaker etc. and is processed as industrial waste now.
請求項１に記載した設備は高周波誘導加熱炉を用いて、発熱体である炭素球を加熱し、発熱した炭素を還元剤として電炉ダスト中の酸化鉄を還元鉄とし、溶融して回収する誘導加熱式還元鉄回収設備。 The equipment described in claim 1 uses a high-frequency induction heating furnace to heat a carbon sphere as a heating element, and uses the generated carbon as a reducing agent to convert iron oxide in electric furnace dust into reduced iron, which is melted and recovered. Heated reduced iron recovery equipment.
請求項２に記載した設備は請求項１に示した設備に関して電炉ダストの加熱中に発生する亜鉛分も亜鉛又は酸化亜鉛として回収可能とした誘導加熱式還元鉄回収設備。 The facility described in claim 2 is an induction heating type reduced iron recovery facility in which zinc generated during heating of electric furnace dust can be recovered as zinc or zinc oxide with respect to the facility shown in claim 1.
