摘　　要：在铜冶炼过程中,侧吹炉炉内结瘤是行业的一大难题,制约着侧吹炉的平稳运行。为解决侧吹炉结瘤问题,本研究对结瘤生长位置及成因进行分析,提出炉顶设置二次风口的优化措施,有效避免二次风室结瘤,消除工艺隐患,保证生产的连续性。同时,对烟道结瘤物质的演变过程、结瘤机理及烟道内烟气走向动力学模型进行研究,提出带有弧度的流线型烟道口结构和水冷膜式壁优化措施。结果表明,烟道温度不再超过200℃,全部趋于平稳,满足侧吹炉生产需求。In the copper smelting process,nodulation in side-blown furnace is a major problem in the industry,which restricts the stable operation of side-blown furnace.In order to solve the problem of nodulation in side-blown furnaces,this study analyzed the growth location and cause of nodulation,and proposed optimization measures for setting secondary air vents on the furnace top to effectively avoid nodules in the secondary air chamber,eliminate hidden dangers in the process,and ensure production continuity.At the same time,the evolution process of nodule substances,nodule mechanism and dynamic model of flue gas trend in flue were studied,and the streamlined flue structure with radian and optimization measures of water-cooled membrane wall were put forward.The results show that the flue temperature no longer exceeds 200℃,and all of them tend to be stable,which meets the production demand of side-blown furnace.
