Embodiment Construction

[0017] Such as figure 1 As shown, the roll-type reverse osmosis membrane element 010 with uniform water distribution of the present invention includes a central pipe 100 , a reverse osmosis membrane 200 , an inlet water diversion net 300 and a pure water diversion net 400 .

[0018] Among them, the reverse osmosis membrane 200 is first folded in half and then wound on the central tube 100 so that the reverse osmosis membrane 200 forms a water inlet channel 500 between the front 201 interlayers, and the reverse osmosis 202 interlayers form a water production channel 600, and the water inlet diversion net 300 Then it is located in the water inlet channel 500 , and the pure water diversion net 400 is located in the produced water channel 600 .

[0019] The reverse osmosis membrane 200 can be folded in two ways, one of which is as Figure 5 As shown, the front side 201 of the reverse osmosis membrane 200 is located outside, and the reverse side of the reverse osmosis membrane 200...

Abstract

The invention discloses a coiling type reverse osmosis membrane element with even water distribution. In the coiling type reverse osmosis membrane element, a central pipe is positioned in a inflow runner, and a plurality of water inlet holes opposite to the inflow runner are distributed on a pipe body; and a reverse osmosis membrane is provided with a concentrated water outlet communicated with the inflow runner at the circumferential surface of the coiling type reverse osmosis membrane element and provided with a pure water outlet communicated with a water producing runner on at least one end surface of the coiling type reverse osmosis membrane element by seal processing. The coiling type reverse osmosis membrane element with even water distribution has the advantages of improvement of the water flow rate on the membrane surface, reduction of the concentration polarization on the membrane surface and reduction of the pollution speed of a coiling type membrane element for prolonging the service life of the membrane element, simple structure and high production operability.

Description

technical field [0001] The invention belongs to the technical field of water purification treatment, and relates to a reverse osmosis membrane element for removing impurities such as sediment, silt, colloid, microorganisms, viruses, organic matter and inorganic salts in water, in particular to a reverse osmosis membrane element with uniform water distribution. Background technique [0002] At present, the known roll-type reverse osmosis membrane element is formed by winding the water purification membrane group composed of pure water diversion net, reverse osmosis membrane and water inlet diversion net on the central water production pipe, wherein the reverse osmosis membrane Folding, the water inlet guide net is located in the water inlet channel formed between the folded inner surfaces of the reverse osmosis membrane, and the pure water guide net is located in the product formed between the folded outer surfaces of the reverse osmosis membrane. In the water flow channel, t...
