螺旋板式换热器在湿法炼锌厂的应用

Application of Spiral Plate Heat Exchanger in Zinc Hydrometallurgy Smelter

分析了螺旋板式换热器在使用中的特点,发现螺旋板式换热器具有换热效率高、设备耗费少等优点。介绍了螺旋板式换热器在湿法炼锌厂生产使用中发现的问题和相应解决方法。生产实践表明,选择904L不锈钢作为换热板材的材质,在高温废酸环境下具有较长的使用寿命,并提出采用耐腐蚀性能更好的石墨代替904L的构想。

The application characteristics of spiral plate heat exchanger were briefly analyzed,and it has the advantage of high efficiency of heat exchange and low-cost etc. The problems and solutions in production of zinc hydrometallurgy were introduced. The 904 L stainless steel exchanger had longer life in high-temperature and acid environment according to practice. It propounded the proposal that carbon can be used in place of 904 L stainless steel.
