Summary of the invention
In place of overcoming above-mentioned the deficiencies in the prior art, this utility model provides a kind of high efficiency self-cleaning desalinization system
System, the configuration of this system is simple, can be effectively improved the producing water ratio of desalinization, solves desalination film and shuts down the problem unpicking and washing difficulty.
For achieving the above object, this utility model adopts the following technical scheme that a kind of high efficiency self-cleaning seawater desalination system,
Switching valve, desalination case, water regulating valve and water pipe, described water inlet pipe and booster pump is cleaned including water inlet pipe, booster pump group, desalination
Group connects, and described booster pump group is connected to desalination by water pipe and cleans switching valve, and this desalination cleans switching valve by first via water
Pipe and the second road water pipe are connected respectively to desalinate the water inlet of case and outlet, are provided with desalination film in described desalination case, described in go out
The mouth of a river is connected with the second water pipe rear portion, road flushing stop valve, and this flushing stop valve connects product water water pipe, on described desalination case
Being provided with water regulating valve, this water regulating valve is connected with strong brine side and away from water inlet, and water regulating valve is divided by pipeline
It is not connected with water inlet pipe and drain pipe.
In technique scheme, at described water inlet pipe, it is provided with the filter for filtering the granule foreign more than 5 μm.
In technique scheme, described booster pump group and desalination are cleaned the water pipe of switching valve and are provided with pressure transducer.
In technique scheme, the product water water pipe that described flushing stop valve connects is provided with effusion meter.
The beneficial effects of the utility model are: this seawater desalination system simple in construction, clean switching valve by switching desalination,
Such that it is able to switching desalination case is desalinated water inlet and the water outlet of film both sides, coordinate and rinse stop valve, reach the purpose of self-cleaning, solve
Desalination film of having determined needs to shut down the problem unpicked and washed, the salt rejection rate of stabilisation systems, increases the service life of desalination film；Adjusted by the water yield
Joint valve arranges pipeline and part strong brine is extracted into booster pump group again, it is achieved part sea water repeats desalination, thus is effectively improved sea
The producing water ratio of water desalination.

Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of high efficiency self-cleaning seawater desalination system as shown in Figure 1, cleans including water inlet pipe 9, booster pump group 2, desalination
Switching valve 4, desalination case 5, water regulating valve 7 and water pipe, described water inlet pipe 1 is connected with booster pump group 2, and described booster pump group 2 is led to
Crossing water pipe and be connected to desalination cleaning switching valve 4, this desalination cleans switching valve 4 by first via water pipe 10 and 11 points of the second road water pipe
It is not connected to desalinate water inlet and the outlet of case 5, it is provided with desalination film 51, described outlet and the second tunnel in described desalination case 5
Water pipe 11 rear portion connects flushing stop valve 8, and this flushing stop valve 8 connects product water water pipe 12, and described desalination case 5 is provided with water
Adjustable valve 7, this water regulating valve and 7 strong brine sides connect and away from water inlet, water regulating valve 7 by pipeline respectively with
Water inlet pipe 9 and drain pipe 13 connect.
In technique scheme, at described water inlet pipe 9, it is provided with the filter 1 for filtering the granule foreign more than 5 μm.Increase
Add filter 1, filter large particulate matter, increase booster pump group and the service life of desalination film.
In technique scheme, described booster pump group 2 and desalination are cleaned the water pipe of switching valve 4 and are provided with pressure transducer
3.Pressure transducer 3 is set and monitors the outlet pressure of booster pump group 2, when pressure is higher or lower than normal range, thus stop
Booster pump group 2 works, and protects system.
In technique scheme, the product water water pipe 12 that described flushing stop valve 8 connects is provided with effusion meter 6.Stream is set
Gauge 5 can conveniently detect aquifer yield.
When using seawater desalination system of the present utility model, sea water passes through booster pump group 2 after water inlet pipe 9 and filter 1
It is pressurized to the operating pressure that 6MPa reaches to desalinate not, cleans switching valve 4 and first via water pipe 10 arrival desalination case through desalination,
And carrying out desalinization through desalination film, the fresh water of output is through rinsing stop valve 8 and effusion meter enters and produces water water pipe transporting to and need
The place wanted, and the strong brine produced is through water regulating valve 7, a part is discharged by drain pipe 13, some dense salt
Water turns again to water inlet pipe the supercharging of intensified pump group 2 through pipeline, is circulated utilization.
When, after this system work certain time, desalination film surface has deposit thus reduces the efficiency of desalination film, now
Needing to be carried out desalination film, closed by flushing stop valve 8, switching valve 4 is cleaned in regulation desalination, is allowed to the second road water pipe even
Logical, now, the sea water after supercharging is redirected back into desalinating in case 5, so that the dilute side of desalination film both sides and strong brine side
Swapping, thus reach automatically to clean the purpose of desalination film 51, after cleaning a period of time, switching valve 4 is cleaned in regulation again, and
Opening flushing stop valve 8, system can work normally.
By the regulation of water regulating valve 7, producing water ratio reaches about 30%, and periodically switching desalination cleans switching valve 4 to desalination
Film 51 is carried out, and stablizes salt rejection rate and reaches 99.4%.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.
