摘要
介绍脱硫系统吸收塔循环泵叶轮严重磨损导致循环泵入口滤网堵塞的情况,原因为石灰石料径过大及品质不合格、循环泵存在汽蚀、吸收塔石膏浆液pH值过低等,提出保持吸收塔石膏浆液合理的密度值、加强废水排放量和废水处理量、脱硫塔补水的过程中保持合理的pH值等防范措施。
This paper introduces Impeller Abrasion of Desul- furization System Absorbing Tower Circling Pump leading to jamming of pump entrance filtertoil, so analyze the causes, those are big diameter and bad quality of limestone, and steam corrosion existing, low pH value of absorbing tower plaster liquid, at last advance countermeasure suggestions, such as, keeping reasonable density of plaster liquid, strengthening waste water management, keeping reasonable pH value.
