Embodiment Construction
[0012] Such as figure 1 As shown, the roll-type reverse osmosis membrane element 10 of the present invention with a variable channel network thickness is composed of two sets of water purification membranes composed of pure water diversion net 100, reverse osmosis membrane 200, and water inlet diversion net 300. 11 is wound on the central water production pipe 400 to form.
[0013] Wherein, the reverse osmosis membrane 200 forms the water inlet flow channel 210 through folding the inner surface, and forms the water production flow channel 220 between the adjacent outer surfaces (the lower outer surface of the reverse osmosis membrane of the bottom water purification membrane group and the water purification of the top layer The upper and outer surfaces of the reverse osmosis membranes of the membrane group also form a water production flow channel after winding), the water inlet flow channel 300 is located in the water intake flow channel 210 , and the pure water flow guide ne...
