Description
技术领域 technical field
本实用新型涉及补给水离子交换除盐系统技术领域，具体来说是一种用于火力发电厂锅炉补给水离子交换除盐系统的正洗排水回收系统。 The utility model relates to the technical field of ion-exchange desalination system for supply water, in particular to a positive washing drainage recovery system for the ion-exchange desalination system for boiler supply water in a thermal power plant.
背景技术 Background technique
在电厂运行中，锅炉补给水系统较多的采用预脱盐加除盐系统，其中预脱盐系统一般采用的超滤加反渗透工艺，在除盐系统中阳离子交换器加阴离子交换器加混合离子交换器的处理工艺由于其出水水质好、系统运行稳定，从而被广泛运用。离子交换除盐系统再生过程一般分为小反洗、反洗、置换清洗、小正洗、正洗等若干步骤。在目前的离子交换除盐系统中，上述步骤中产生的废水一般通过地沟的方式排至再生废水贮存池，进而通过废水泵转移至工业废水处理站进行处理。其不仅造成水资源的浪费，还增加了工业废水处理站的加药量和能耗，增加了运行费用。实际上，离子交换器再生正洗排水采用的是反渗透系统的产水，且正洗一般在小正洗完成之后进行，此时正洗排水中悬浮物以及含盐量都比较低，水质较好，可以有条件地进行回收使用。如何开发出一种针对于离子交换除盐系统的正洗排水回收系统已经成为急需解决的技术问题。 In the operation of power plants, the boiler feed water system mostly adopts the pre-desalination plus desalination system, and the pre-desalination system generally adopts the ultrafiltration plus reverse osmosis process, and the cation exchanger plus anion exchanger plus mixed ion exchanger in the desalination system The advanced treatment process is widely used because of its good effluent quality and stable system operation. The regeneration process of the ion exchange desalination system is generally divided into several steps such as small backwash, backwash, displacement cleaning, small positive wash, and positive wash. In the current ion exchange desalination system, the wastewater generated in the above steps is generally discharged to the regeneration wastewater storage pool through the trench, and then transferred to the industrial wastewater treatment station for treatment through the wastewater pump. It not only causes waste of water resources, but also increases the dosage and energy consumption of industrial wastewater treatment stations, and increases operating costs. In fact, the water produced by the reverse osmosis system is used to regenerate the positive washing drainage of the ion exchanger, and the positive washing is generally carried out after the small positive washing is completed. At this time, the suspended matter and salt content in the positive washing drainage are relatively low, and the water quality is relatively low Well, it can be recycled conditionally. How to develop a positive washing drainage recovery system for the ion exchange desalination system has become an urgent technical problem to be solved.
