The invention relates to an efficient open type net pipe flowing channel reverse osmosis membrane element. The efficient open type net pipe flowing channel reverse osmosis membrane element comprises acentral flow guide pipe, and a separating layer which coats the periphery of the central flow guide pipe, wherein the separating layer is a membrane bag layer manufactured by coiling a plurality of membrane bags and open separating nets in the same direction; the open separating nets are arranged in inlet water flowing channels between the surfaces of adjacent membrane bag layers and are in convex point contact manner with the surfaces of the membrane bags, and fine rhombic separating nets are used for connecting the convex points so as to form rhombic wide open type flowing channels betweentwo rows of convex point shaped separating nets on the contact surfaces of the membrane bags in the water flowing in and out directions; the inner side edges of the membrane bags and the open separating nets are fixedly connected with the central flow guide pipe and are radially arranged from the center; the membrane bags and the open separating nets are screwed in the same direction so as to formthe membrane bag layer; the coiled membrane bag layer is coiled, coated and sealed with glass fibers and epoxy resin, and the two ends are equipped with stress-resistant plates.

The invention relates to a high-efficiency open network pipe flow channel reverse osmosis membrane module, including a membrane shell, a central water production pipe arranged in the membrane shell, and several membrane elements arranged around the central water production pipe. The membrane element has an open network pipe flow channel, and the membrane shell One end of the water inlet is provided with a water inlet flange end cover, and the inner side of the water inlet flange end cover is provided with a water inlet swirling flow guide plate; one end of the membrane shell outlet is provided with a water outlet flange end cover, and the inner side of the water outlet flange end cover is installed There is a water outlet swirling diversion plate; the ends of the central water production pipe are respectively provided with water production joints; the inner peripheral wall of the membrane shell is provided with a circular card groove, and a retaining ring is arranged in the card groove, and the retaining ring is tightly pressed against the end cover; Along the water inlet direction, it includes at least two sets of membrane elements connected in series before and after, and the two membrane elements connected in series in the axial direction are communicated through a diversion tube connector. The application can simultaneously take into account the advantages of resistance to pollution and blockage, small pressure loss, uniform water flow distribution, larger effective area of ​​the membrane, simple structure, convenient maintenance, and long service life.
