摘　　要：阳极炉烟气高温、含尘且具有腐蚀性,从二次燃烧室远距离输送至余热锅炉具有一定的困难和复杂性。以浙江某铜冶炼厂改造阳极炉为例,对阳极炉烟气远距离输送管道的材料选择、设计推导过程进行了研究,设计了一款高温冶炼烟气输送管道。本设计烟管通过在管内分段设置焊接环状挡板,在挡板间充填保温隔热层、耐火耐磨层的方案,低成本、高效率地解决了高温烟气远距离输送问题。High temperature and dusty anode furnace off-gas is corrosive,making it difficult and complex to deliver it remotely from the secondary combustion chamber to the waste heat boiler.Taking the renovation of anode furnace in a copper smelter in Zhejiang as an example,the paper studies the material selection and design derivation of the long-distance AF off-gas delivery pipeline,and conducts the design of high-temperature smelting off-gas delivery pipeline.This duct design solves the problem of long-distance high-temperature off-gas delivery with low cost and high efficiency by providing welded circular dampers in sections inside the pipeline and filling insulation layer and fire-resistant&wear-resistant layer between the dampers.
