Smelting furnace, comprising: a gas conveying device, pipeline, valve and fuel supply device, furnace chamber is provided with a heating chamber and a melting chamber, a heating chamber is communicated with the melting chamber, a heating chamber is arranged at the upper part of the heating chamber inlet, a heating chamber is arranged at the upper part of the heating chamber of the air outlet, the melting chamber is arranged at the lower part of the melting chamber outlet, melting chamber the side wall provided with a plurality of inlet, inlet and outlet end and smelting chamber. The case is energy-saving and environmental friendly. It can smelt a variety of metals and alloys. It can realize aluminum smelting by fire process, and can directly smelt aluminum alloy. Any mineral smelting, can realize carbon thermal reduction of metal oxides, namely the use of soil or garbage can also make alloy, is able to perform wonders, soil into gold, is the real alchemy. Coke free iron smelting, iron making and steelmaking can be completed synchronously, the heat produced by steelmaking can be fully utilized, and the waste gas can be processed uniformly. Production of glass, ceramic frits, paohuajian etc.. A variety of raw materials can be used to refine valuable elements. It can reduce the emission of sulfur dioxide and other pollutants. The utility model can make full use of resources without producing slag.
【技术实现步骤摘要】
本专利技术涉及高炉、冲天炉、冶炼炉、反射炉、熔炉等冶金设备、窑炉设备领域,具体 是一种冶炼熔炉。
技术介绍
现有的高炉、冲天炉、冶炼炉、反射炉、熔炉等普遍存在排出的烟气温度太高、热能 利用率低,能耗大,污染严重。高炉、冲天炉等必须使用焦炭,用焦炭提供热源、作为支撑料 柱、过滤熔液材料,焦炭资源有限,价格昂贵,焦炭生产污染环境、增加能耗。冲天炉在使用 过程中存在烟气冲天,污染严重,高炉生产中产生大量的高炉煤气,如利用不当必然带来大 量的能源浪费。高炉煤气利用设备投资大,利用效益不高。冲天炉烟气中的一氧化碳含量也 很高,烟气温度很高,这些都带来大量的能源浪费。高炉炼铁需进行矿石烧结、球团等原料 预加工,增加能耗和费用支出;不能直接使用低品位矿石原料,增加原料成本,不能充分利 用资源;矿石中的贵重金属无法提取,导致资源浪费,废渣污染环境,占用土地资源。炼铁与 炼钢无法同步完成,需进行铁水转移、二次吹炼,增加冶炼成本;炼铝普遍采用电解铝,能耗 大,污染严重,废渣赤泥难以处理、利用,占用土地资源,火法炼铝至今仅停留在实验阶段。 炼硅只能用电炉,耗能巨大。所有金属冶炼均产生 ...
