Background technology
In naturally osmotic, water is flowed from low concentration to high concentration, and counter-infiltration is made pure by being pressurizeed at high concentration water source
Net hydrone produces pure water through reverse osmosis membrane, while will be unable to various impurity and harmful substance the giving up with concentration penetrated
Water discharges.
Reverse osmosis technology has been widely used in the fields such as Water warfare at present.Reverse osmosis membrane under normal operating conditions, reverse osmosis
Permeable membrane may be polluted by inorganic matter dirt, colloid, microorganism, metal oxide etc., and these electrodeposition substances are on the surface of the film, it will draw
Play counter-infiltration and put output drop or desalination rate and decline, therefore, in order to recover good permeable and desalination performance, it is necessary to film progress
Chemical cleaning.
When the reverse osmosis membrane in water purifier is rinsed, a scouring electromagnetic valve is connect on concentrated water branch road, by electromagnetism
Valve is opened, and is carried out positive flushing to reverse osmosis membrane using low pressure and mass flow, i.e., is intake from water inlet end, then flowed out from concentrated water branch road
Concentrated water after flushing, to wash away the pollutant of counter-infiltration film surface.
The above-mentioned backwashing manner to reverse osmosis membrane, fouling and gradually to water inlet reverse osmosis membrane can be caused at the production water end (W.E.)
Extreme direction extends, and last whole film surface is covered with dirt so that the life-span of reverse osmosis membrane substantially reduces.
The content of the invention
Therefore, the technical problem to be solved in the present invention be to overcome it is of the prior art reverse osmosis membrane is rinsed it is halfway
Defect.
Therefore, the present invention provides a kind of reverse osmosis membrane filter element rinse-system, including：Reverse osmosis membrane filter element, it includes：With entering
The water inlet that water pipe is connected；For the water purification mouth of water purification outflow；And the concentrated water spout for concentrated water outflow；Flushing water can pass through institute
State concentrated water spout to flow into inside the reverse osmosis membrane filter element, arranged after being rinsed to the reverse osmosis membrane filter element by the water inlet
Go out.
Described rinse-system, including：Second concentrated water pipe, one end are connected with the water inlet pipe；Back flush pipe, one end
It is connected to the second concentrated water tube side-by-side on the water inlet pipe, the back flush pipe other end communicates with the concentrated water spout,
Flushing water is entered in the reverse osmosis membrane filter element by the concentrated water spout, and is flowed out by the second concentrated water pipe.
Be connected between the second concentrated water pipe and the water inlet pipe by first mouth of a river, the direction flush pipe with it is described
It is connected between water inlet pipe by second mouth of a river, relatively described second mouth of a river in first mouth of a river is set close to the water inlet.
Described rinse-system, in addition to：The first concentrated water pipe being connected with the concentrated water spout, the back flush pipe with
The first concentrated water pipe is connected by the 3rd mouth of a river, and relatively described 3rd mouth of a river of the first concentrated water pipe is away from described dense
3rd water check valve is installed on the position at the mouth of a river.
Described rinse-system, the first water check valve is provided between first mouth of a river and second mouth of a river, carried out reverse
During flushing, the 4th water check valve is closed, and first water check valve is closed.
Described rinse-system, the first concentrated water pipe close with the second concentrated water manifold.
Described rinse-system, the reverse osmosis membrane filter element include：Housing, central tube is arranged with axle center；First sealing
Circle, it is arranged on the central tube close to one end of the water inlet；Second sealing ring, it is arranged on the central tube close to institute
State one end of concentrated water spout and be oppositely arranged with first sealing ring, first sealing ring and the second sealing ring tensioner exist
On the inwall of the housing.
A kind of counter-infiltration system, including：Described rinse-system；Pure water pipe, one end is connected at the water purification mouth, another
End is connected with water tank；Primary purifying module, the one end of the water inlet pipe away from the water inlet is connected to, to flushing water
Carry out primary purifying.
