喷雾降温技术在阳极炉高温烟气降温中的应用

摘要

介绍了喷雾降温技术的特点,以及喷雾降温系统工艺及技术参数的设置、控制逻辑和应用效果.该技术在国内铜冶炼烟气冷却中应用较少,而国外几家铜厂已开始取代余热锅炉,成功应用在转炉烟气的冷却上.因其温度控制精度高、投资省、设备简单和占地空间小等优点,将在高温烟气的冷却上广泛应用.喷雾降温技术应用于云南铜业冶炼加工总厂阳极炉高温烟气的冷却,整个喷雾降温系统运行正常,实现了初期的降温目标要求,有效地解决了固定阳极炉高温烟气的冷却问题,使烟气得到了有效除尘净化.%This paper introduced the characteristics of spray cooling technology, and the technological parameters setting, control logic and application effects of spray cooling system. The technology was rarely used for cooling flue gas of copper smelting at home, successfully applied for cooling flue gas instead of exhaust-heat boiler in several copper factory in other countries, widely used for cooling high temperature flue gas because of the advantage such as high precision temperature controlling, low invest, simple e-quipment, taking up small space. The spray cooling technology was applied for cooling high temperature flue gas of anode furnace in smeltery of Yunnan Copper, the whole system ran normally, realized initial cooling target, solved the problem of cooling high temperature flue gas of the fixed anode furnace, and cleaned flue gas efficiently.
