环缝洗涤塔下段循环水系统增加应急泄水管的必要性

Necessity of Adding Emergency Drainage Pipe in Circulating Water System of Lower Part of Annular Gap Scrubbing Tower

高炉煤气净化、环缝洗涤塔下段循环水系统生产中常出现循环水泵气蚀、水泵检修及机械、液压、电气、计器系统等异常,造成水封水位升高,威胁生产。为解决这一问题增加了应急泄水管,保证了安全稳定。

Cavitation erosion of circulating water pump often occurs in production of the circulating water system of blast furnace gas purification and of the lower part of annular gap scrubbing tower. The abnormal phenomena take place in water pump maintenance and in the testing systems of machinery, hydraulic pressure, electric and gauge, causing high water level of water seal and a threat to production. In order to solve this problem, it is necessary to add emergency drainage pipes to ensure stable and safety production.
