二级反渗透装置是借助压力使水分子强迫透过对水分子有选择透过作用的反渗透膜,即是反渗透净水的原理,这种装置为反渗透装置根椐各种物料的不同渗透压,可以大于渗透压的反渗透法进行分离、提取、纯化和浓缩。可除去水中98%以上的溶解性盐类和99%以上的胶体、微生物、微粒和有机物等,成为现代纯水、太空水(超纯水)工程首选的最佳设备。
二级反渗透生产除盐水,并作为中温中压锅炉的补水,目前为国内首创。
The two-stage reverse osmosis system was used to produce desalting water that was used as additional water of medium temperature and medium pressure boiler.
另外还在一级反渗透膜处理水出口与二级高压泵进水口之间设置了加碱液装置和中间水箱。
In addition, a lye-feeding device and a middle water tank are arranged between the water outlet of the primary reverse osmosis membrane and the water inlet of the secondary high-pressure pump.
