Incorporated by reference to reference to Fig. 3 to Fig. 8, membrane component body includes central tube group 11, multiple counter-infiltration diaphragm groups 13 and two
Sealant layer 14, the central tube group 11 includes the waste pipe 113 of DI 111 and multiple spaced settings, multiple useless
Water pipe 113 is arranged around DI 111, is formed in DI 111 and formed in described pure water pipeline 111a, waste pipe 113 institute
State waste line 113a.Each described counter-infiltration diaphragm group 13 is respectively provided with the Part I inside central tube group 11 (not
Sign) and the Part II (sign) positioned at central tube group 11 outside, each waste pipe 113 and DI 111 by one instead
The Part I of infiltration diaphragm group 13 separates；The Part II of multiple counter-infiltration diaphragm groups 13 is centered around around central tube group 11
Form multi-layer film structure.Two sealant layers 14 are respectively arranged at multiple counter-infiltration diaphragm groups 13 in the length side of central tube group 11
Two ends upwards, and it is bonding with multiple counter-infiltration diaphragm groups 13.
The reverse-osmosis membrane element 10 also includes the second end cap 17, and the second end cap 17 is covered on the another of membrane component body
End, the first end cap 15 and the second end cap 17 are simultaneously adhesively fixed with corresponding sealant layer 14 respectively
The one counter-infiltration diaphragm group 13 of correspondence of each waste pipe 113 of reverse-osmosis membrane element 10, it is multiple such that it is able to realize
Film roll is bent, can increase runner quantity, is conducive to improving raw water flux, and solves the long osmotic pressure of counter-infiltration diaphragm 131 not
Foot causes part counter-infiltration diaphragm 131 and not up to filters the problem of purpose；Reverse osmosis is sealed respectively by two sealant layers 14
The two ends of permeable membrane piece group 13 are (it should be noted that sealant layer 14 can not block the inner tube of DI 111 or waste pipe 113
Mouthful), prevent water from flowing out from the two ends of counter-infiltration diaphragm group 13 or flowing into, multiple outside avris of counter-infiltration diaphragm group 13 can be formed
Stream water inlet, middle waste pipe 113 discharges the raw water water route of waste water.
When above-mentioned reverse-osmosis membrane element 10 is used, raw water is intake by effluent, and runner narrows, and water inlet area reduces, and may be used also
With the water inlet flow-guiding screen 133 in counter-infiltration diaphragm group 13 using low thickness, continue to reduce water inlet area, and flow process also increases
It is long, therefore the time that raw water is contacted with counter-infiltration diaphragm 131 can be increased, improve the raw water rate of recovery；Meanwhile, because reducing original
Water intake area, can increase counter-infiltration diaphragm group 13112 infiltration membrane surface water velocity (enter water flux it is certain when,
The relation entered between water flux Q and water velocity V is V=Q/S；Wherein, S is water inlet area, specifically, S=Ld；L is water inlet
21 diaphragm lengths are held, d is section thickness, and effluent mainly reduces L, reduced naturally with little water inlet flow-guiding screen 133 in addition
Thickness d), it is thus possible to reduce the surface concentration polarization of counter-infiltration diaphragm 131, reduce the pollution speed of the reverse-osmosis membrane element 1010
Degree, is conducive to improving the raw water rate of recovery, so as to improve the waste problem of raw water, reaches the effect for saving raw water.
Each described counter-infiltration diaphragm group 13 includes counter-infiltration diaphragm 131, water inlet flow-guiding screen 133 and pure water flow-guiding screen
135；
The just inward-facing doubling of the counter-infiltration diaphragm 131 of each counter-infiltration diaphragm group 13 is arranged, multiple described anti-
The Part II overlapping of infiltration diaphragm group 13 simultaneously circumferentially winds the central tube group 11 jointly；The same counter-infiltration diaphragm
Water inlet flow channel is formed between 131 front interlayers；Formed between the reverse side interlayer of the two neighboring counter-infiltration diaphragm 131 and produce current
Road；The water inlet flow-guiding screen 133 and the waste pipe 113 are located in water inlet flow channel, and the pure water flow-guiding screen 135 is located at and produces current
In road.
Each counter-infiltration diaphragm group 13 includes counter-infiltration diaphragm 131, water inlet flow-guiding screen 133 and pure water flow-guiding screen 135；
Water inlet flow-guiding screen 133 and pure water flow-guiding screen 135 can be separately positioned on the tow sides of counter-infiltration diaphragm 131, and raw water is in reverse osmosis
The front flowing of permeable membrane piece 131, and in the presence of osmotic pressure, from counter-infiltration diaphragm 131 just towards reverse osmosis membrane piece 131
Reverse side infiltration pure water, pure water produces the reverse side in counter-infiltration diaphragm 131 and under the guide functions of pure water flow-guiding screen 135 to pure
Water pipe 111 flows.Wherein, counter-infiltration diaphragm 131 can cause front to adjoin with front by doubling, and reverse side is adjoined with reverse side,
Unnecessary contact is avoided, so as to prevent pure water to be contaminated；Can be just during the doubling of counter-infiltration diaphragm 131 during practical operation
Inward-facing doubling can also be the inside doubling of reverse side, and according to actual conditions Rational choice is carried out.In the present embodiment, it is each
The just inward-facing doubling of the counter-infiltration diaphragm 131 of individual counter-infiltration diaphragm group 13 is arranged, the Part II of multiple counter-infiltration diaphragm groups 13
Overlapping and common circumferentially winding central tube group 11；Water inlet flow channel is formed between the front interlayer of same counter-infiltration diaphragm 131；It is adjacent
Formed between the reverse side interlayer of two counter-infiltration diaphragms 131 and produce water flow passage；Water inlet flow-guiding screen 133 and waste pipe 113 are located at water inlet
In runner, pure water flow-guiding screen 135 is located at and produces in water flow passage.Now, it is separate between water inlet flow channel and product water flow passage, and thoroughly
Isolation, can effectively ensure that the water inlet flow-guiding screen 133 of each counter-infiltration diaphragm group 13 is not anti-with DI 111 and others
The reverse side contact of the counter-infiltration diaphragm 131 of infiltration diaphragm group 13；The pure water flow-guiding screen 135 of each counter-infiltration diaphragm group 13 not with
The front face of the counter-infiltration diaphragm 131 of waste pipe 113 and other counter-infiltration diaphragm groups 13；Raw water only flows in water inlet flow channel
Dynamic finally to be discharged by waste pipe 113, pure water only flows in water flow passage is produced and is finally discharged by DI 111, so as to avoid pure water
Pollution, it is ensured that clean-up effect.In order to smoothly derive pure water, in the present embodiment, product water flow passage can be set except leaning on
The equal closing seam in other sides beyond the side of nearly DI 111, so that produce water flow passage only having towards DI 111
Pure water outlet 53；The film bag that water flow passage forms a side opening of three side seal one is now produced, film sack is against DI 111, limit
Determining the pure water in film bag can only flow towards DI 111；Raw water produces pure water, pure water shape after the effect of counter-infiltration diaphragm 131
Into in film bag and flowing to sack in DI 111.During practical operation, carry out realizing when can operate by wound membrane close
Envelope, while the sealing station at two ends can also carry out second sealing using two sealant layers 14, and then realizes preferably close
Envelope effect.
