The opening of water pipe, water purification diaphragm group is after the water producing pipe of the center of winding, and whole outer surface carries out environmental sealing with outer adhesive tape.To be clean
Former water (generally through the water of ultrafiltration) flow into former water flow passage, a part of water through reverse osmosis membrane filtration formed pure water enter produce
Water flow passage, and can not be raised by the ion concentration in the water of reverse osmosis membrane, and can be gradually along former water flow passage ion concentration
Raise.If the ion concentration of former water own is higher, flows through and be likely to occur hypersaturated state after former water flow passage concentrates and separate out
Solid, affects the performance and used life of reverse osmosis membrane assembly, when the most former water speed in former water flow passage is slower, and reverse osmosis
Film surface easily produces concentration polarization phenomenon so that salt rejection rate and producing water ratio reduce.For avoiding the problems referred to above, it is common that control former
The concentration of water or control salt rejection rate, the function of reverse osmosis membrane assembly fails to be fully used.
Utility model content
Therefore, this utility model fails, for reverse osmosis membrane assembly function in prior art, the technical problem made full use of,
Purpose is to provide the reverse osmosis unit of a kind of made full use of reverse osmosis membrane assembly purification function improving salt rejection rate.
Reverse osmosis unit of the present utility model include reverse osmosis membrane assembly, described reverse osmosis membrane assembly include reverse osmosis membrane and
Being positioned at the former water flow passage of described reverse osmosis membrane both sides and produce water flow passage, described former water flow passage two ends are connected with a discrepancy water pipe respectively,
It is respectively equipped with a valve on discrepancy water pipe described in two, comes in and goes out described in two and connected by a return-flow catheter between water pipe, described backflow

Principle of the present utility model and the most progressive effect:
Described reverse osmosis unit is when actually used, and coming in and going out water pipe described in one can be as water inlet pipe, another described Water Exit
Described valve on described water inlet pipe, as dense water pipe, is opened by pipe, and the described valve closing on described dense water pipe, now lead to
Cross high-pressure pump and can be passed through former water to be clean to described former water flow passage through described water inlet pipe.Former water is flow to by described former water flow passage
During the described reverse osmosis membrane assembly other end, a part of water forms pure water through described reverse osmosis membrane and enters product water flow passage,
The most permeable remaining water is that dense water can flow out through described dense water pipe, then converges, so with former water through the backflow of described return-flow catheter
After again flow into former water flow passage and filter, with this circulating filtration, it is possible to decrease dense water rate, make full use of the purification merit of reverse osmosis membrane
Can, and the use power of high-pressure pump can be reduced.When dense water will reach saturation, can open on described dense water pipe
Described valve, releases dense water, then turns off the described valve on described water inlet pipe, by high-pressure pump by former water by described dense
Water pipe is passed through in described former water flow passage, and the most described dense water pipe is converted to water inlet pipe, and described water inlet pipe is converted to dense water pipe, former water
Reversely flowing through described former water flow passage, dense water one end that script ion concentration in described former water flow passage is higher is diluted by former water, can
It is prevented effectively from solid to separate out.
To sum up, compared to traditional reverse osmosis unit, reverse osmosis unit of the present utility model is additionally arranged described return-flow catheter
With described valve, can realize concentrate recirculation with this and refilter, the flow direction that simultaneously can realize the water in described former water flow passage switches,
Avoid dense water supersaturation to separate out solid, the purification function of described reverse osmosis membrane assembly can be given full play to, improve producing water ratio, and can
