硫酸低温热能回收蒸汽发生器的结构设计

The Structural Design of Sulphuric Acid Steam Generator for Low Temperature Heat Recovering

分析了硫酸低温热能回收蒸汽发生器的现状,针对目前采用单管板U型管换热器作为硫酸发生器的弊端,设计了一种性能稳定的蒸汽发生器,它采用管壳式固定管板列管换热器,提高了换热管的使用效率。硫酸低温热能回收蒸汽发生器适用于硫酸浓度不恒定、吸收温度不恒定的复杂工艺条件。

This article analysed the current situation to sulphuric acid steam generator for low temperature heat recovering. In order to avoid the problems of not up to our expect by U-type tube heat exchanger with single tubesheet,the efficient sulphuric acid steam generator was introduced. By adopting tube-and-shell heat exchanger with fixed tubesheet,it had high efficiency. The new steam generator applied to complex conditions of sulfuric acid production.
