Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] Such as figure 1 As shown, the embodiment of the present invention provides a diversion net, including first ribs 7 and second ribs 8 intersecting each other, there is an angle between the first ribs 7 and the second ribs 8, and the The angle of the obtuse angle in the angle is 115°-135°, and the water inlet direction corresponding to the diversion net 3 is along the bisector of the obtuse angle.
[0027] Specifically, the water entry angle C of the diversion net 3 of the present invention is 135°-115°. When the raw water is filtered by the diversion net 3, the disturbance of the flow between the upper and lower layers of the diversion net 3 is the largest. Compared with the diversion net 3, The direction of water flow is the angle bisector of the angle between the first rib 7 and the second rib 8, and the actual filtration angle of the reverse osmosis membrane is 5...

Abstract
The invention provides a flow guide net, a reverse osmosis membrane filter element and a filter. The water inlet angle of the flow guide net is 135-115 degrees, the thickness is 0.12-0.38 mm, the spacing of the flow guide net is 550-800 microns, and the rib diameter of the flow guide net is 50-100 microns; a local flow channel is narrowed, the local flow velocity is high, the upper and lower wall surfaces of lap joints of longitudinal ribs and transverse ribs alternately appear, the speed increase area is enlarged, the turbulence effect is enhanced, and the thrust and the mass transfer effect of solute diffusion are enhanced; and the connecting area of the flow guide net and the membrane is reduced, the filtering area of the membrane is increased, and the water outlet flow and the anti-pollution performance of the filter element are improved. The anti-pollution concentrated water separation net for the reverse osmosis membrane filter element is simple in structure and easy to manufacture, can be widely applied to water treatment processes of reverse osmosis, nanofiltration, ultrafiltration, pervaporation and the like, and has good social benefits and economic benefits.
Description
technical field [0001] The invention relates to the technical field of water cleaning, in particular to a diversion net, a reverse osmosis membrane filter element and a filter. Background technique [0002] Membrane fouling is the biggest problem faced by reverse osmosis membrane elements. The research on the cause and mechanism of membrane fouling in the prior art focuses on the modification of reverse osmosis membrane and the improvement of the structure of reverse osmosis membrane filter elements. In the structure of the roll-type reverse osmosis membrane filter element, the diversion net not only plays the role of supporting the flow channel and guiding the liquid, but also acts as a turbulence promoter in the filter element to reduce the concentration polarization and pollution on the membrane surface and improve the reverse osmosis membrane. The water quality and flow rate of the filter element, therefore, the structural characteristics such as the thickness, spacing, ...
