摘要
为节约淡水资源,广东惠来电厂1 000 MW超超临界机组直流锅炉补给水处理工艺中采用了反渗透海水淡化(SWRO)技术并取得成功,系统出力、出水水质、脱盐率均达到设计要求,证明反渗透技术能很好满足海域电厂大型机组锅炉水处理的使用要求。介绍SWRO系统及其各设备运行情况;探讨了典型SWRO系统的关键问题:预处理系统加药量的调整,能量回收装置的应用,反渗透膜产水的取样以及反渗透浓水排放等。
To conserve fresh water resources, the sea water reverse osmosis （SWRO） desalination technology was used in feed water treatment of 1 000 MW ultra supercritical once-through boiler in Guangdong Huilai power plants. The system output capacity, effluent quality, desalinization ratio have reached the design requirements. The results prove that SWRO can meet the request of feed water treatment of large coastal power plant. The equipments and operation condition of SWRO system were introduced. The key problems of typical SWRO system, such as pretreatment system dosage adjustment, application of energy recovery device PX, anti pernleate thick drain, and sampling methods in permeate were discussed.
