铜冶炼烟气制酸过程中升华硫的成因及解决措施

Causes and Solutions of Sublimated Sulfur in Sulfuric Acid Production From Copper Smelting Flue Gas

铜冶炼烟气制酸是硫酸工业的重要组成部分。卢阿拉巴铜冶炼厂是刚果(金)第一座大型火法炼铜厂,硫酸产品市场良好,但在生产中升华硫现象时发,严重影响生产系统的稳定性及设备安全。文章在生产实践基础上结合化学反应基本原理分析升华硫的成因并探讨解决措施,总结调控升华硫的经验。

Acid making from copper smelting flue gas is an important part of sulfuric acid industry.Lualaba copper smelter is the first large pyrometallurgical copper smelter in the Democratic Republic of the Congo.The sulfuric acid product market is good,but the sublimation sulfur events occur frequently in production,which seriously affects the stability and capacity of the production system.Based on the production practice,combined with the basic principle of chemical reaction,this paper analyzes the causes of elemental sulfur,discusses the solutions,and summarizes the experience of regulating sublimated sulfur.
