摘要
聚丙烯装置的干燥系统自动控制系统无法正常运转,近一年来严重影响着安全生产。因此,对此自动控制系统进行了改造,在物位监控回路中加装了延迟自锁装置,经过技术改进,成功的解决了问题,并为其他类似自动控制系统的改造提供了可借鉴的成功经验。
The level automatic control in the dryness system of polypropylene plant didn＇t work in recent year ,affecting the safe production of the plant. So we improved the automatic control system by adding delay self-locking device in the level monitor loop. After the innovation, the problem has been solved successfully, and have provided successful experiences in similar automatic control system innovations.
