Abstract:

In power plants,the conductivity increase of effluent in demineralized water tanks occurs frequently. By means of theoretical calculation and case introduction,the causes have been analyzed in three aspects,including:the top sealing of demineralized water tank is not tight enough,the anticorrosion coating on the tank inner walls has many defects,and the equipment of boiler make-up water system may be abnormal. Based on these analyses,the co-rresponding solutions are brought forward.

Key words: demineralized water, conductivity, polyurea elastomer

摘要：

除盐水箱出水电导率升高在电厂时有发生,针对除盐水箱出水电导率升高现象,通过理论计算和案例介绍,从3个方面进行了原因分析。分析原因包括:除盐水箱顶部密封不严,水箱内壁防腐层缺陷,以及锅炉补给水系统出现设备异常。在对各项原因进行分析的基础上,指出了相应的解决方法。
