摘要
生产装置大检修周期延长、循环水系统实施高浓缩倍数运行方案后,给循环水系统的长周期运行管理带来挑战。本文在总结往年不停车清洗经验的基础上,对粘泥剥离和清洗过程中如何加强分散效果作了改进,收到一定效果。
In view of produce installation overhaul cycle extended, and high cycle of concerntration has been treated in recirculating cooling water system, It was difficult to assure heat transfer running control for longer circulating. Based on summarized on-line chemical cleaning bygone years, make fouling strip and disperser better, Pretty ideal result has been obtained.
