Background
Along with the development of membrane technology, the application field of the membrane technology is more and more extensive, and the application field of the membrane technology is gradually extended into a plurality of fields such as drinking water, boiler makeup water, medicine, food, brackish water desalination, industrial wastewater treatment and the like, and particularly, a roll-type membrane element occupies most of market share due to the compact design and low price. However, since the stock solution has a complex composition and usually contains suspended matters, colloid and other impurities, the stock solution needs to be subjected to strict pretreatment, and even then the flow channels of the rolled membrane are still easy to be blocked, so that the membrane pressure difference is increased, the flux is reduced, and irreversible pollution and damage can be caused in severe cases. Therefore, in order to further adapt the rolled film to various application fields, it is required to improve the contamination resistance of the film element and to extend the service life of the film element. Besides improving the performance of the membrane, the component design of the coiled membrane element is more important than the design of the membrane element, and is mainly reflected in the selection of the water supply diversion screen, including the design of the thickness of the water supply diversion screen, the screen spacing, the water inlet angle, the shape of the screen and the like.
In the prior art, the design of the screen is mainly concentrated on the shape and arrangement of screen wires of the screen, such as a wide flow channel diversion screen disclosed in CN202725044U, and the wide flow channel diversion screen comprises a plurality of longitudinal ribs which are longitudinally and parallelly arranged, wherein adjacent longitudinal ribs are connected by a plurality of transverse ribs, longitudinal flow channels are formed between the adjacent longitudinal ribs, the cross section dimension of the longitudinal ribs is triangular or isosceles trapezoid, and the transverse ribs are connected in the middle of the triangle or isosceles trapezoid and are not contacted with Moss, so that the effective utilization area of a membrane is increased, and water flows to generate turbulence. However, the contact position between the triangle or isosceles trapezoid and the membrane surface is sharp, so that the membrane surface is easily severely worn due to friction during operation, the contact surface between the longitudinal ribs and the membrane is not in point contact, but in surface contact, the contact surface is large, and suspended matters and colloid are easily accumulated near the contact surface. CN205550049U discloses a circumferential wide flow channel rolled membrane assembly, its water-producing and flow-guiding separation net includes transverse ribs, longitudinal ribs, and also includes a plurality of vertical ribs which are bent and folded to form corrugated structure. The transverse ribs and the longitudinal ribs are connected in a crisscross manner to form intersection points, and the bending ends of one side of each vertical rib are respectively connected with each intersection point correspondingly to form a water production flow passage in a triangular area. The utility model designs the flow passage screen at the water producing side, increases the sectional area of the flow passage of produced water and reduces the flow resistance of produced water. However, the contaminants trapped by the rolled membrane are mainly accumulated on the water inlet side, and the improvement of the water producing side separation net does not solve the problem of membrane pollution on the water inlet side.
