Specific embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, are not
It is determinate, it is impossible to which that protection scope of the present invention is limited with this.
Embodiment 1：
As shown in figure 3, the in-line arrangement membrane stack of the achievable auto purification of the present invention, mainly by front end face pressing plate 10, follow
17 rear end face pressing plate 11 of ring plate of water route, in-line arrangement lamina membranacea 12, rear end face pressing plate 11 and panel beating electrode assemblie are constituted.
Press-fit one group of in-line arrangement lamina membranacea 12 between front end face pressing plate 10 and rear end face pressing plate 11 side by side and form annular seal space
Body.Front end face pressing plate 10, rear end face pressing plate 11, in-line arrangement lamina membranacea 12 closed assembly are fixed on one using pull bar successively
Rise.Raw water entrance 13, concentrated water outlet 14 is formed with front end face pressing plate, produce water out 15 and attaching plug 16.Follow
Ring water route version 17 is built-in with circulation waterway 43.
As shown in figure 4, in-line arrangement lamina membranacea 12 is by housing 21, internal 24 structure of electrode group 19 and double-side filtering film
Into, being formed between 12 double-side filtering film 24 of in-line arrangement lamina membranacea and produce water cavity 22, product water cavity 22 connects with water out 15 is produced
It is logical.When each in-line arrangement lamina membranacea 12 is press fit together, the raw water main flow connected with raw water entrance 13 is formed in bottom
Road 18, forms the concentrated water sprue 20 connected with concentrated water outlet 14 on top.When before multiple in-line arrangement lamina membranaceas 12
After when being superimposed, between each jamb surface of the framework housing 21 of adjacent in front and back in-line arrangement lamina membranacea 12 closely
Gluing, sealing, forms concentrated water space 23 between the filter membrane 24 of adjacent in-line arrangement lamina membranacea 12.
As shown in Figure 5,6, in the present embodiment, housing 21 is rectangle frame, and two panels filter membrane 24 covered outside respectively
The frame both sides of frame.Housing plane is respectively perpendicular on top frame, bottom frame, side edge frame in housing to set
Put concentrated water through hole 25, raw water through hole 26 and produce water through hole 28, produce 27 horizontal frame connection product water of water branch flow passage and lead to
Hole 28 and product water cavity 22.
The gap that can connect concentrated water space 23 is left with the top of raw water through hole 26 in the bottom of concentrated water through hole 25.
Concentrated water through hole 25 is superimposed as concentrated water sprue 20, produces water through hole 28 and is superimposed composition product water sprue, raw water through hole
26 are superimposed as raw water sprue 18.When raw water is flowed into from raw water sprue 18, from the gap of raw water through hole 26
Into in concentrated water space 23, the product water in product water cavity 22 after filter membrane 24 is filtered is via product water branch flow passage 27
Discharged by producing water out 15 in being collected to product water sprue.The concentrated water stayed in concentrated water space 23 is from concentrated water
Discharged by concentrated water outlet 14 in collecting in concentrated water sprue 20 after overflowing in the gap of through hole 25.
The mode in use frequently with cross flow filter of filter membrane 24, the present invention are prevented to cut down concentration polarization
The a large amount of pollutant in surface are piled up and mitigate fouling membrane, in 12 raw water sprue 18 of front end face pressing plate 10 and in-line arrangement lamina membranacea
Circulation waterway plate 17 is set between concentrated water sprue 20, and circulation waterway therein 43 enters raw water sprue 18
Mouthful with the outlet of concentrated water sprue 20, to increase the surface velocity of filter membrane 24.In general, surface stream
Speed is too low cannot to wash away the pollutant for being deposited in 24 surface of filter membrane；The too high then energy consumption of surface velocity is big, economical
Property it is poor, while be likely to bring the damage of filter membrane 24, so surface velocity is controlled within the specific limits.
After circulation waterway 43 are increased, the exit velocity of the inlet flow rate and concentrated water sprue 20 of raw water sprue 18 is poor
It is not relatively smaller, it is easier to control the surface velocity of filter membrane 24 in the range of needs.
As shown in Figure 1 and Figure 2, in prior art, on front end face pressing plate arrange concentrated water outlet 2, produce water out 3,
Raw water entrance 1 and power connection.Its raw water is entered inside membrane module by raw water entrance 1, is entered respectively straight per piece
Water stream channel 4 on column lamina membranacea is distributed to 5 surface of filter membrane of in-line arrangement lamina membranacea, produces in pressure and electrode 6
Dielectrophoresis force in the presence of, produce water through filter membrane 5 enter produce water cavity 7, finally by produce water out 3 flow out
Membrane module, the waste water after concentration along film Surface runoff, collect runner and go out into concentrated water outlet 2, Jing concentrated waters by Jing current
Mouth flows out membrane module.
The outlet of the entrance and concentrated water sprue 9 of the raw water sprue 8 of connection raw water entrance 1 and water stream channel 4 exists
The cross section of fluid channel product of film working portion is identical, if producing water ratio is improved, then the outlet of concentrated water sprue 9
Flowing velocity will decline.As shown in figure 3, when the outlet of the entrance and concentrated water sprue 9 of raw water sprue 8 cuts
Under area same case, raw water sprue 8 enters water 1m/s, producing water ratio 95%, then the outlet stream of concentrated water sprue 9
Speed be 1 × (100%-95%)=0.05m/s, the exit velocity of the entrance and concentrated water sprue 9 of raw water sprue 8
Than for 20:1, i.e., both current differences are away from 20 times.If it is desired to improving the outlet lowest speed of concentrated water sprue 9 extremely
0.5m/s so that pollutant are not deposited on inside, raw water sprue 8 is limited by operating pressure and can not be increased due to producing water
Plus, such producing water ratio has reformed into 65%, and the response rate will be affected.
Based on above-mentioned viewpoint, the in-line arrangement membrane stack of the achievable auto purification of the present invention, in entering for raw water sprue 18
Circulation waterway 43 is set between mouth and the outlet of concentrated water sprue 20, makes part concentrated water flow back into raw water sprue 18
Entrance side, then the problems referred to above can be effectively improved.
As shown in fig. 7, following when the concentrated water of control total 50% flows back to the addition of raw water sprue 18 from circulation waterway 43
Ring, then the flow velocity in raw water sprue 18 be changed into 1 × (100%+50%)=1.5m/s, compared with increasing without loop condition
0.5 times, the exit velocity of concentrated water sprue 22 is changed into 1 × (50%+5%)=0.55m/s, compared with without circulation feelings
Condition increased 10 times.Then the velocity ratio between the outlet of the entrance of raw water sprue 18 and concentrated water sprue 20 is
1.5:0.55=30:11≈3:1, both current differences are reduced to 3 times away from by 20 times, can if the flow of circulation is improved
Reduce its gap again.So as the effect of inner loop causes film Surface runoff speed to be effectively increased, can both increase
Plus flowing velocity can ensure that producing water ratio is constant again.
When multiple in-line arrangement membrane stacks parallel water distribution, due to diverse location in-line arrangement membrane stack linear loss not
Together so that between different in-line arrangement membrane stacks, have that dynamic pressure is poor, thus the flow between each in-line arrangement membrane stack is also
Different, so overall water distribution is also uneven.And the in-line arrangement membrane stack of circulation waterway 43 is carried than general
In-line arrangement membrane stack raw water entrance it is less, thus water distribution is evenly, and we carry out hypothesis below：
A) there is identical two in-line arrangement membrane stack A and B parallel running, be state when two heaps are common in-line arrangement membrane stack
I, for state I I when two heaps adopt circulation waterway 43；
B) keep A heap flows under I, II state constant, i.e. QAI=QAII。
