Description
技术领域technical field
本实用新型属于水处理设备领域，具体涉及一种用于反渗透设备反渗透膜组件的正反清洗系统。The utility model belongs to the field of water treatment equipment, in particular to a positive and negative cleaning system for reverse osmosis membrane components of reverse osmosis equipment.
背景技术Background technique
反渗透是一种借助于选择透过(半透过)性膜的工力能以压力为推动力的膜分离技术，当系统中所加的压力大于进水溶液渗透压时，水分子不断地透过膜，经过产水流道流入中心管，然后在一端流出水中的杂质，如离子、有机物、细菌、病毒等，被截留在膜的进水侧，然后在浓水侧出水端流出，从而达到分离净化目的。Reverse osmosis is a membrane separation technology that relies on the force of the selectively permeable (semi-permeable) membrane and can be driven by pressure. Pass through the membrane, flow into the central tube through the produced water flow channel, and then flow out at one end. Impurities in the water, such as ions, organic matter, bacteria, viruses, etc., are trapped on the inlet side of the membrane, and then flow out at the outlet end of the concentrated water side to achieve separation. Purification purpose.
众所周知，反渗透膜在对原水过滤时，不可避免的要受到原水中杂质的污染，原水中的截留物会沉积在反渗透膜表面，造成反渗透膜过滤孔逐渐堵塞，膜的产水量会逐渐下降，当产水量降低至标准产水量的75％时，就需要对反渗透膜进行清洗，使其重新恢复过滤能力。本领域技术人员都知道，目前市场上出现的反渗透膜清洗系统均是采用从进水侧进水进行清洗，这样会导致浓水侧清洗效果不均衡，严重影响到反渗透膜的清洗效果，同样会导致浓水侧的堵塞，缩短反渗透膜的使用寿命，同时也会降低产水效率。As we all know, when the reverse osmosis membrane filters raw water, it will inevitably be polluted by impurities in the raw water. When the water production rate drops to 75% of the standard water production rate, it is necessary to clean the reverse osmosis membrane to restore its filtration capacity. Those skilled in the art know that the reverse osmosis membrane cleaning systems currently on the market are all cleaned from the water inlet side, which will lead to unbalanced cleaning effect on the concentrated water side and seriously affect the cleaning effect of the reverse osmosis membrane. It will also lead to clogging of the concentrated water side, shorten the service life of the reverse osmosis membrane, and reduce the water production efficiency.
