稀硫酸浓缩工艺运行问题及改善措施

Operational problems in dilute sulfuric acid concentration and improvement measures

介绍负压蒸酸器蒸发浓缩硫酸的生产工艺。针对稀硫酸浓缩装置在生产过程中真空异常、氯气吸收效果不好或水封失效会对环境造成影响等异常,制定改善措施。改善后稀硫酸浓缩装置稳定运行。

The production process of sulfuric acid evaporation and concentration in negative pressure is introduced.In view of the abnormal conditions in dilute sulfuric acid concentration,improvement measures are formulated.Abnormal conditions include abnormal vacuum,environmental impact caused by poor absorption of chlorine or by water seal failure.After improvement,the dilute sulfuric acid concentration unit operates stably.
