摘要: 河源电厂2列连续电除盐(CEDI)设备已投运近5年,接近使用年限,近1年来在制水过程中频繁出现产水水质恶化现象。对造成问题的可能原因逐项进行排查,针对具体情况进行了相关处置,主要包括化学清洗、层级再生、管路改造、循环冲洗、更换个别膜块等。实践结果表明,采取各项措施后河源电厂CEDI设备产水水质恢复至正常水平,在保障电厂水汽品质的同时,使即将到期的设备得到正常使用,安全性和经济性均有所体现。

Abstract: The 2 series of Continuous Electro-deionization(CEDI) equipment of Heyuan power plant have been put into operation for four and half years, which is approaching the service life and the quality of the product water deteriorated frequently over the past year. The possible causes for the problem were investigated one by one and relevant measures were proposed respectively, including chemical cleaning, level regeneration, transformation of pipeline, rinse cycle, and replacement of individual membrane block. The results showed that the quality of product water of CEDI equipment returned to normal level after various measures had been taken. As a result, the steam quality of Heyuan power plant is guaranteed and the about-to-expire equipment can work normally, realizing security and economy.
