摘 要: 为了研究铅塔冷凝器内锌蒸气冷凝过程对冷凝器内壁的传热情况,通过对锌蒸气冷凝过程传热机理的分析、推导,得出了铅塔冷凝器内锌蒸气冷凝过程传热数学模型。由该模型可知,锌蒸气冷凝过程的传热量主要决定于冷凝器内锌蒸气的温度和冷凝器内壁温度,要提高锌蒸气冷凝过程的传热量,可以通过降低冷凝器内壁温度来达到目的, 但其温度值的优化值为800℃左右。韶关冶炼厂铅塔冷凝器实际运行情况表明,该模型能较好地反映铅塔冷凝器内锌蒸气冷凝过程中向铅塔冷凝器内壁面的传热,这将对铅锌冷凝器的设计以及生产操作具有一定的指导意义。

Abstract:In order to study of the heat transfer from condensing zinc vapor to interior wall of the condenser of lead column, based on analysis and reasoning of the mechanism of heat transfer in the course of condensation of zinc vapor, a mathematical model of heat transfer on the condensation of zinc vapor in condenser of lead column is proposed. The model indicates that the quantity of heat transfer of condensation of zinc vapor has a very close relation with the temperature of zinc vapor condensation and interior wall of condenser, and the reducing of interior wall temperature in condenser can enhance the quantity of heat transfer of zinc vapor condensation, the optimum value range of interior wall temperature in condenser is about 800℃. The factual case of heat transfer of zinc vapor condensation in condenser of lead column in Shaoguan Smelter indicates that the mathematical model can preferably reflect heat transfer from condensation of zinc vapor in condenser to the interior wall of condenser. Some significant results toward design and operation of condenser of a lead column are attained from the mathematical model.
