Reverse osmosis multistage exchanges water saving system against current

一种反渗透多段互换逆流节水系统

Abstract

The utility model discloses a reverse osmosis multistage exchanges water saving system against current realizes intaking and the positive reversed flow's of dense water pipe way rivers adjustment to first membrane group, secondary membrane group and tertiary membrane group through changing opening of in pipeline valve with closed. Wash the salt crust attached to epimembranal face through positive reverse flow to the effect of membrane is washed in the realization, and then can improve the life of membrane, with performance reverse osmosis membrane's maximum potential itself, makes the water rate of producing bring up to 85% by 75%, and then reaches the purpose that the multistage exchanged water conservation against the current.
本实用新型公开了一种反渗透多段互换逆流节水系统,通过改变管路中阀门的开启和闭合来实现对第一膜组、第二膜组和第三膜组的进水和浓水管路水流的正反向流动的调整。通过正反向水流来冲洗附着在膜表面的盐垢,从而实现冲洗膜的效果,进而能够提高膜的使用寿命,以发挥反渗透膜本身的最大潜能,使产水率由75%提高到85%,进而达到多段互换逆流节水的目的。
