摘　　要：锅炉补给水系统主要是对水进行处理,水质的好坏直接关系到电厂的正常运行和经济效益。因此,电厂锅炉补给水系统中通过安装中压紫外线杀菌装置,其杀菌性和经济性具有显著优势。经过试验分析了解到:中压紫外线杀菌装置细菌杀灭率高达99%;连续运行3个月,制水系统中均未发现微生物污染现象;夏季时反渗透进水和反渗透浓水之中的菌落总数控制在10 CFU/mL以下;冬季时超滤和反渗透系统中未发现微生物污染的现象,水质波动能够得到有效控制;较小流量有助于提升杀菌的效果;吨水杀菌耗电量为0.06 kW·h。文章针对中压紫外线杀菌装置进行了全面的分析,将其应用到锅炉补给系统之中,分析其经济性和杀菌效果,具有重要的意义和作用。Boiler supply water system is mainly to the water treatment,the water quality is directly related to the normal operation and economic benef its of the power plant.Therefore,the sterilization ability and economy have signif icant advantages through the installation of the medium pressure ultraviolet sterilization device in the boiler supply water system of the power plant.After test analysis,it is learned that the bacterial killing rate of medium voltage ultraviolet sterilization device is as high as 99%.Without continuous operation in the water production system,the total bacterial colonies in the reverse osmosis inlet water and reverse osmosis concentrated water is controlled below 10 CFU/mL,no microbial contamination is found in the ultraf iltration and reverse osmosis system in winter,and the fluctuation of water quality can be effectively controlled.The small flow helps to improve the effect of sterilization,the power consumption of a ton of water is 0.06 kW·h.This paper makes a comprehensive analysis of the medium voltage ultraviolet sterilization device,which applies it to the boiler supply system,and analyzes its economy and sterilization effect.
