Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
This utility model embodiment provides a kind of pair of section counter-infiltration system, as shown in figure 1, including：One section of reverse osmosiss dress
Put 1, two-stage nitration reverse osmosis unit 2, the concentrated water outlet of one section of reverse osmosis unit 1 and the water inlet of two-stage nitration reverse osmosis unit 2 are by the
One pipeline is connected, and this pair of section counter-infiltration system also includes：Buffer 3 and filter 4；
Wherein, buffer 3 includes：Negative pressure canceller 5, tank body 6 and air bag 7；
Negative pressure canceller 5 is fixed on 6 outside top of tank body；
Air bag 7 is located in tank body 6, and air bag 7 is connected with negative pressure canceller 5；
7 bottom of air bag is provided with intake-outlet, and the intake-outlet is connected with first pipeline by the second pipeline；
Filter 4 is installed on the first pipeline.
When above-mentioned pair of section counter-infiltration system is started shooting, one section of reverse osmosis unit 1 is first opened, waste water is by one section of reverse osmosiss dress
Put 1 water inlet to enter in one section of reverse osmosis unit 1, concentration is carried out in one section of reverse osmosis unit 1, after then processing
The concentrated water for obtaining is flowed out by the concentrated water outlet of one section of reverse osmosis unit 1, and a part can flow to two-stage nitration reverse osmosis again by filter 4
Saturating device 2, but mainly it is flowed in the air bag 7 of buffer 3 by the intake-outlet of buffer 3, and air bag 7 has elasticity, because
This air bag 7 gradually can increase with the continuous inflow of concentrated water, while the pressure in air bag 7 also gradually can increase.When two-stage nitration reverse osmosis
After device 2 is started shooting thoroughly, the concentrated water of one section of reverse osmosis unit 1 is no longer flow towards buffer 3, but first passes through filter 4 in concentrated water
Float etc. filtered, then flow to two-stage nitration reverse osmosis unit 2 again.In this start process, buffer 3 serves slow
The effect of punching, it is ensured that the available machine time of two-stage nitration reverse osmosis unit 2, prevents the concentrated water lateral pressure of one section of reverse osmosis unit 1 too high,
Damage the reverse osmosis membrane of one section of reverse osmosis unit 1.
When above-mentioned pair of section counter-infiltration system shuts down, one section of reverse osmosis unit 1 is first closed, that is to say, that one section of reverse osmosis
The concentrated water of device 1 no longer flows out, and now, two-stage nitration reverse osmosis unit 2 is also not turned off.Concentrated water in air bag 7 is due to two-stage nitration reverse osmosiss
The effect of the high-pressure pump of device 2, after filtering from filter 4, is flowed into two-stage nitration reverse osmosis by the water inlet of two-stage nitration reverse osmosis unit 2
Thoroughly in device 2.In this shutdown process, the pressure in air bag 7 promotes concentrated water and flows out from air bag 7, and air bag 7 is with concentrated water
Outflow and constantly diminish.Now, buffer 3 equally serves the effect of buffering, does not also shut down in two-stage nitration reverse osmosis unit 2
In the case of, make concentrated water flow to two-stage nitration reverse osmosis unit 2, make two-stage nitration reverse osmosis unit 2 can continue to run well, it is ensured that two-stage nitration
The unused time of reverse osmosis unit 2.It will be appreciated by persons skilled in the art that one section of reverse osmosis in this utility model embodiment
Device 1 and two-stage nitration reverse osmosis unit 2 each mean the reverse osmosis unit for including high-pressure pump thoroughly.
In running, when two-stage nitration reverse osmosis unit 2 breaks down, the concentrated water of one section of reverse osmosis unit 1 is mainly led to
The intake-outlet for crossing buffer 3 is flowed in the air bag 7 of buffer 3, enable within a certain period of time one section of reverse osmosis unit 1 after
It is continuous to run well.When one section of reverse osmosis unit 1 breaks down, the concentrated water in air bag 7 is after the filtration of filter 4, then passes through
The water inlet of two-stage nitration reverse osmosis unit 2 is flowed in two-stage nitration reverse osmosis unit 2, makes two-stage nitration reverse osmosis unit 2 within a certain period of time
Can continue to run well.When the pressure in air bag 7 is negative pressure, start negative pressure canceller 5, eliminate the negative pressure in air bag 7.For
Protection system and prevent foreign body from entering, when negative pressure canceller 5 starts, stop two-stage nitration reverse osmosis unit 2.Need explanation
It is that negative pressure canceller 5 can adopt negative pressure canceller commonly used in the art, this utility model here not to be specifically described.
During normal operation, waste water is entered in one section of reverse osmosis unit 1 by the water inlet of one section of reverse osmosis unit 1,
Concentration is carried out in one section of reverse osmosis unit 1, the concentrated water obtained after then processing is gone out by the concentrated water of one section of reverse osmosis unit 1
Mouth flows out, and first passes through filter 4 and concentrated water is filtered, be then flowed into two by the water inlet of two-stage nitration reverse osmosis unit 2 again
Two-stage nitration concentration is carried out in section reverse osmosis unit 2.
As seen from the above, buffer 3 has not only acted as the effect of buffering in the entire system, also acts storage energy
Effect.As buffer 3 keeps stable pressure, therefore the concentrated water of one section of reverse osmosis unit 1 with pressure flows directly into two-stage nitration reverse osmosis
Saturating device 2.So the double section counter-infiltration systems provided using this utility model embodiment, not only can prevent foreign body from entering, keep away
Exempt from contaminated system, can be with the consumption of save energy.
It should be noted that filter 4 may be mounted at the first pipeline being connected with the second pipeline any side of position.
