铅锌密闭鼓风炉熔炼卧式热风炉的开发研究

Development of horizontal hot-air furnace for lead-zinc imperial smelting furnace

密闭鼓风炉炼铅锌时需从风口鼓入900℃左右的热风,热风由立式热风炉提供。立式热风炉体积庞大,结构复杂,运行中不便检修维护。笔者开发设计出一种卧式热风炉,不仅体积相对小,运行过程中还可以对其中的某个箱体进行更换、清扫、维护,并且热效率高。

Hot air at a temperature of about 900 ℃ is required to be blown into the imperial smelting furnace for lead-zinc smelting,which is supplied by the vertical hot-air furnace.The vertical hot-air furnace features large volume and complicated structure and inconvenience for maintenance during operation.The author of the paper has developed a kind of horizontal hot-air furnace,which not only has smaller volume and higher heat efficiency,but also is convenient for replacing,cleaning and maintaining some of chambers during operation.
