摘要: 电化学水垢去除技术是一种主动式水垢控制技术,可将水垢以固体形式从循环冷却水中析出。通过理论计算得出该技术处理能力计算表达式,并结合工程实践状况分析了影响处理能力的因素,重点分析了影响设备传质条件的因素。在此基础上,提出了电化学水垢去除技术的2个改进方向:即将电化学水垢去除技术与其他除垢技术联用,以及发展与现有水垢阴极沉积思路相反的电化学阳极除碱技术。

关键词: 水垢, 电化学除垢, 电化学阳极除碱

Abstract: Electrochemical scale removing technology is a kind of active scale controlling technology,which can precipitate the scale from the circulating cooling water in solid form. The removing ability calculation expression of the technology is obtained by theoretical calculation. The factors influencing the removing ability are analyzed according to the engineering practice status,and the factor influencing the equipment mass transfer condition is analyzed emphatically. Based on this,two improvement directions of electrochemical scale removing technology are presented. One is the combination of electrochemical scale removal technology with other scale removing technologies,and the other one is the development of anodic electrochemical alkali removing technology,which is contrary to the existing scale cathodic deposition concept.

Key words: scale, electrochemical scale removal, electrochemical anodic alkali removal
