磷酸结垢的技改措施

Technical improvement measures of phosphoric acid scaling

提高稀磷酸生产能力的关键是提高稀磷酸系统的运行率,而影响稀磷酸运行率最大的原因就是渣场回水泵的结垢问题,导致回水量不能满足生产需求。云峰分公司通过分析论证结垢的成因,利用现场条件采取针对性措施对结垢问题进行技改,使稀磷酸运行率有大幅提高,产能得到有效提升,经济效益和社会效益显著。

The key to improve the production capacity of dilute phosphoric acid is to improve the operation rate of dilute phosphoric acid system.The most important reason affecting the operation rate of dilute phosphoric acid is the fouling problem of backwater pump in slag yard.As a result, the amount of backwater can not meet the production demand.Through analysis and demonstration of the causes of scaling in Yunfeng Branch, targeted measures are taken to improve the scaling problem by taking advantage of the on-site conditions.The operation rate of dilute phosphoric acid has been greatly improved.Production capacity has been effectively increased.Economic and social benefits are remarkable.
