[0002] The reverse osmosis membrane in the prior art, such as the integrated reverse osmosis membrane disclosed in the utility model patent with the authorized announcement number CN201470326U, the integrated osmosis membrane includes a membrane end cover and a cylindrical membrane element, and the membrane element is provided with The ultra-low pressure reverse osmosis membrane made of spiral rolling, the membrane end cover is fixedly connected to both ends of the membrane element and the two are fixed into one body, and the membrane end cover is provided with a water outlet port, a water inlet port and a concentrated water port; However, because the water inlet interface of this reverse osmosis membrane is generally deviated from the center of the membrane end cover, it is easy to cause inconsistent pressure in the membrane element, thereby affecting the purification effect. At the same time, due to the high pressure in some areas, it is easy to damage the membrane element

Abstract

The invention relates to coating water purification technology, and in particular relates to a reverse osmosis membrane applicable to coating water purification. According to the invention, the technical scheme is as follows: the reverse osmosis membrane applicable to coating water purification comprises a central pipeline, a membrane element, a left end cover and a right end cover, wherein the membrane element is formed by winding the reverse osmosis membrane around the central pipeline; the left end cover and the right end cover are respectively connected with two ends of the membrane element hermetically; and a circular raw water inlet is formed on the right end cover. The reverse osmosis membrane can effectively balance the pressure in the membrane element, so that the membrane element is not easily damaged due to overlarge pressure and also has good purification effect.
