铅塔冷凝器的散热研究

Study on the Radiating Heat of Lead Column Condenser

分析了韶关冶炼厂锌精馏过程中铅塔冷凝器实际冷凝能力不足,冲顶事故时有发生的原因,并对二系统1#铅塔冷凝器散热进行了测试。测试结果表明:除顶部壁面处于良好的工作状况外,冷凝器各竖壁面的温度沿高度方向的变化显著,温差较大;在同一高度处,冷凝器北壁面温度明显高于东、西两侧壁面温度。

The actual condensing capacity of 1 # lead column condenser is evidently smaller than that of design in Shaoguan Smelter, and the radiating heat state of the condenser of 1 # lead column is measured. The results show： for the vertical wall of the condenser, there is evident temperature change along the direct of the height, and the difference of the north wall is larger than that of the east and west walls.
