The other side in road forms concentrated water outflow side 202, and the raw water influent side 201, the concentrated water outflow side 202 are located in described
The both ends of heart pipe 101, and there is the pure water inlet 105 communicated with the production water flow passage, institute on the side wall of the central tube 101
At least one end for stating central tube 101 forms pure water outflux, is provided in each water inlet flow channel into water filter 104.Such as Fig. 3
Shown, the region on the water inlet filter 104 between the central tube 101 and the concentrated water outflow side 202 offers two
Item washes away runner, and on the water inlet filter 104 being unfolded, the first end of runner is washed away described in every from the water inlet filter
Raw water influent side of the distance of 104 raw water influent side 201 than the second end for washing away runner from the water inlet filter 104
201 distance is close.Each runner that washes away includes that the flowing to of water flow of the length direction on the water inlet filter 104 extends
First runner 301, and the turbulent flow runner 302 of the two sides of the first runner 301 is set, along the first runner 301
On direction, the turbulent flow runner 302 be equipped with it is a plurality of, the first end of the turbulent flow runner 302 is connected to the first runner 301,
And the second end of the turbulent flow runner 302 with a distance from the raw water influent side 201 than the first end of the turbulent flow runner 302 from
For the raw water influent side 201 apart from remote, the first end of the turbulent flow runner 302 compares institute with a distance from the raw water influent side 201
The water inlet end for stating first runner 301 is remote with a distance from the raw water influent side 201.
Reverse osmosis membrane assembly in the prior art as shown in Figure 1, include central tube 101, produce water filter 102, diaphragm and into
Water filter 104 after position places as illustrated, is rolled into membrane module.For the rolled membrane module of the traditional structure, transport for a long time
Will appear film surface fouling after row and influence film properties, fouling region is analyzed, obtained fouling form as shown in Fig. 2, from
Fig. 2 film surface fouling form is it is found that easily fouling region 203 is distributed mainly on close to central tube 101 and close to the film of concentrated water water outlet
On face, less scaling region 204 is distributed mainly on far from the film surface at central tube 101 and close to raw water influent side 201.Its
In, it is seriously primarily due under certain rate of recovery close to 202 scaling tendency of concentrated water outflow side, the raw water of concentration is compared to raw water
The speed of entrance is slow；It is mainly for the reason of film surface scaling tendency is greater than far from central tube 101 at the central tube 101
Since its transmembrane pressure is greater than far from film surface at central tube 101, so that scaling fouling is serious.
And the reverse osmosis membrane assembly in the present embodiment, runner is washed away by being cut on water inlet filter 104, washes away runner
Interior to stop without water inlet filter twine, water flow can be greater than non-cut place in the flow velocity washed away in runner.Raw water is through raw water influent side
201 enter in water inlet flow channel, and the water inlet end through first runner 301, which enters, to be washed away in runner, and second then through turbulent flow runner 302
End outflow, the water after concentration are flowed out through concentrated water outflow side 202, and the pure water for penetrating reverse osmosis membrane 103 is flowed into through producing water flow passage
The pure water water inlet water inlet of central tube 101, exports from the stream of pure water of one end of central tube 101 and flows out.Due to washing away in runner
Flow velocity is greater than the flow velocity of non-cut place, to produce the difference of water flow velocity, therefore will form one from runner is washed away to two sides
An impact force, which can wash away the loose dirt in initial stage easy fouling region 203, can reduce loose dirt and be attached to
The trend of film surface, while the loose dirt being flushed away is drained with concentrated water, residence time of the dirt in membrane module is reduced, to reach
Extend the service life of reverse osmosis membrane 103, the reverse osmosis membrane assembly do not need to increase new material can be realized extend it is reverse osmosis
The service life of membrane module.
The runner that washes away in the present embodiment is predominantly on easy fouling region 203, also has part to cross fouling line of demarcation 205 and prolongs
Less scaling region 204 is reached, the dirty area being distributed as far as possible broken up can be made so more greatly, to reduce local knot
Dirty trend.
In alternative embodiments, the turbulent flow runner 302 is only arranged in the side of the first runner 301, described
The quantity of turbulent flow runner 302 can be set to one or be configured according to demand, but satisfaction is needed not influence filter 104 of intaking
Support strength.
In alternative embodiments, it is not provided with the turbulent flow runner 302, washes away the length direction and water inlet filter of runner
The flow direction of water flow on 104 is consistent, and this setup can also wash away the loose dirt in initial stage easy fouling region 203.
In alternative embodiments, the raw water influent side 201, concentrated water outflow side 202 setting position according to reverse osmosis
The structure of permeable membrane component is configured, and the runner that washes away intake on filter 104 is carried out according to the flow direction of water flow on water inlet filter 104
Setting is needed to meet and be washed away described in ratio with a distance from raw water influent side 201 of the first end for washing away runner from the water inlet filter 104
The second end of runner is close with a distance from the raw water influent side 201 from the water inlet filter 104.
Embodiment 2
The difference of the present embodiment and above-described embodiment is, washes away that runner is whole to be respectively formed the rapids as shown in figure 4, described
Runner 302 is flowed, the runner that washes away is equipped with a plurality of and arc-shaped, the side formation raw water influent side 201 of the water inlet flow channel, institute
One end that raw water influent side 201 is located at the central tube 101 is stated, the first end for washing away runner is close to the water inlet filter
The 104 starting point setting rolled, second end are arranged close to end is rolled.
Raw water enters water inlet filter 104 through raw water influent side 201, and a part of water, which enters, to be washed away in runner through washing away runner
Second end outflow, the raw water after concentration are flowed out through concentrated water outflow side 202, penetrate the pure water of reverse osmosis membrane 103 through producing water flow
Road flows into the pure water water inlet water inlet of central tube 101, exports and flows out from the stream of pure water of one end of central tube 101, due to washing away stream
There is no the obstruction of water inlet filter twine in road, therefore washes away the flow rate of water flow in runner and be greater than in adjacent water inlet filter 104
Water flow velocity, to be formed, water velocity is poor, can wash away the loose dirt at easy fouling region 203, and a part is discharged with concentrated water, reduces
The dirty residence time；A part is transferred to less scaling region 204 and shares scaling tendency, forms a sacrifice compensation mechanism, whole
On delay the serious trend of 103 local scaling of reverse osmosis membrane.
In alternative embodiments, on the water inlet filter 104 of expansion, the runner that washes away is linear, and the punching
The first end of brush runner from it is described water inlet filter 104 raw water influent side 201 with a distance from than the second end for washing away runner from
The distance of the raw water influent side 201 of the water inlet filter 104 is close.
In alternative embodiments, the shape for washing away runner can be set to other arbitrary shapes.
