摘　　要：一种铜冶炼电除尘器进口超温自动调解保护装置,目的在于有效控制熔炼电除尘器进口温度,通过增加喷雾降温装置,降低电除尘器进口温度,同时使烟气增湿,有效调节熔炼烟气粉尘比电阻,调节控制烟气中三氧化硫含量,解决熔炼电除尘器因系统产量增加造成的电除尘器进口温度超标、阳极板变形、收尘效率下降、设备腐蚀等问题。An automatic protection device for preventing overtemperature at the inlet of ESPs is intro-duced.The device can effectively control the inlet temperature of ESPs.The associated spray cooling de-vice humidifies smelting off-gas while reducing the EPS inlet temperature,thus effectively adjusting the specific resistance of the dust and the content of sulfur trioxide in the off-gas,and solving the problems caused by the output increase of smelting system,such as overtemperature at the ESP inlet,deformation of anode plate,decline of duct collection efficiency,equipment corrosion,etc.

关 键 词：收尘效率下降 阳极板变形 比电阻
