In order to reduce the pollution speed of spiral wound reverse-osmosis membrane element, the utility model proposes a kind of new spiral wound
Reverse-osmosis membrane element, refer to Fig. 1, and Fig. 1 shows the knot of the embodiment of spiral wound reverse-osmosis membrane element one of the present utility model
Structure schematic diagram.
The spiral wound reverse-osmosis membrane element 100 includes central tube group 10, twines and be located at along the circumference of the central tube group 10
Multiple reverse osmosis membrane groups 20 and miscellaneous part in the outside of central tube group 10.
Fig. 2 is refer to, above-mentioned central tube group 10 includes DI 11 and surround the DI 11 and spaced multiple
Waste pipe 12；Wherein, Fig. 3 is refer to, one end of the DI 11 is provided with pure water outlet 111, and the perisporium of DI 11 is opened
It is communicated with the pure water blasthole 112 of the inner passage of DI 11；One end of each waste pipe 12 is provided with waste water discharge opening
121, and the perisporium of waste pipe 12 is provided with the waste water blasthole 122 for connecting the inner passage of waste pipe 12.
It should be noted that the quantity of the waste pipe 12 of central tube group 10 determines the quantity of reverse osmosis membrane group 20,
Determine the size of DI 11.Specifically, a waste pipe 12 one reverse osmosis membrane group 20 of correspondence is set, and in other words, waste water
The quantity of pipe 12 is more, and the quantity of reverse osmosis membrane group 20 is also more, and the flux of spiral wound reverse-osmosis membrane element 100 is bigger,
Correspondingly, the aperture of the DI 11 also correspondingly increases.For the particular number of waste pipe 12, it can be entered according to actual conditions
Row is set, and does not do specific restriction herein.
Each reverse osmosis membrane group 20 in above-mentioned multiple reverse osmosis membrane groups 20 be respectively provided be oppositely arranged front and
Reverse side, and each reverse osmosis membrane group 20 front the one end of reverse osmosis membrane group 20 from central tube and a waste pipe 12 it
Between pass through rear doubling, form formation between the intake tunnel that is connected with waste pipe 12, the reverse side of adjacent two reverse osmosis membranes group 20
The production aquaporin connected with DI 11.
Specifically, refer to Fig. 4, each reverse osmosis membrane group 20 include reverse osmosis membrane 21, water inlet flow-guiding screen 22 and
Pure water flow-guiding screen 23；Wherein, the front of the reverse osmosis membrane 21 in the one end of reverse osmosis membrane group 20 from central tube and a waste water
Rear doubling is passed through between pipe 12, is formed between above-mentioned intake tunnel, the reverse side of adjacent two reverse osmosis membrane 21 and forms production aquaporin.
Water inlet flow-guiding screen 22 and pure water flow-guiding screen 23 are separately positioned on the tow sides of reverse osmosis membrane 21, that is to say, that water inlet water conservancy diversion
Net 22 is installed in intake tunnel, and pure water flow-guiding screen 23 is installed in pure water passage.Raw water is made in the water conservancy diversion of water inlet flow-guiding screen 22
Flowed under in intake tunnel, and in the presence of osmotic pressure, from reverse osmosis membrane 21 just towards reverse osmosis membrane 21
Reverse side infiltration pure water；Raw water in intake tunnel enters in production aquaporin through reverse osmosis membrane group 20 and forms pure water,
Pure water flows under the guide functions of pure water flow-guiding screen 23 to DI 11.
Now, it is separate between water inlet flow channel and production water flow passage, and thoroughly isolate, it can effectively ensure that each is anti-
Permeate the water inlet flow-guiding screen 22 of diaphragm group 20 not with the reverse osmosis membrane 21 of DI 11 and others reverse osmosis membrane group 20
Reverse side is contacted；The pure water flow-guiding screen 23 of each reverse osmosis membrane group 20 not with the waste pipe 12 and other reverse osmosis membrane
The front face of the reverse osmosis membrane 21 of group 20；That is, raw water is only flowed finally in water inlet flow channel from the row of waste pipe 12
Go out, pure water only flows in production water flow passage is finally discharged by DI 11, so as to avoid pure water from polluting, it is ensured that clean-up effect.
It should be noted that DI 11 is only provided with the pure water in pure water outlet 111, production aquaporin in its one end
It can be discharged from DI 11；Because production aquaporin has certain width, thus, can then cause production aquaporin close to DI 11
Pure water outlet 111 a side water velocity it is very fast, and produce the one of pure water outlet 111 of the aquaporin away from DI 11
Side water velocity is slower, thus, can then cause the production aquaporin adjacent to a side of the pure water discharge outlet of DI 11 and be somebody's turn to do
The pure water concentration for producing a side of pure water outlet 111 of the aquaporin away from DI 11 is different, thus, can then cause reverse osmosis
The side of pure water outlet 111 of the permeable membrane piece group 20 away from DI 11 is easily contaminated.
, please for the pollution speed of the side that reduces pure water outlet 111 of the reverse osmosis membrane group 20 away from DI 11
