Abstract
The utility model relates to a water-saving reverse osmosis system which comprises a reverse osmosis device, a pure water tank and a secondary pure water tank, wherein a water delivery pipe is arranged at a water outlet of the reverse osmosis device, and is connected with the pure water tank and the secondary pure water tank; a flow direction change-over valve is arranged on the water delivery pipe, and selects the fluid flow direction according to fluid conductance in the water delivery pipe; and a washing circuit for cleaning the reverse osmosis device is arranged between the secondary pure water tank and a water inlet of the reverse osmosis device. The flow direction change-over valve can control water in a valve body to flow to the pure water tank or the secondary pure water tank according to the conductance of a water body in the water delivery pipe; when the reverse osmosis device is out of operation, the collected secondary pure water can be used for washing the reverse osmosis device; concentrated water can be prevented from remaining in the reverse osmosis device; a protective effect is exerted on the reverse osmosis device; and the secondary pure water is used for washing, so that large amount of pure water for washing is not required, and large number of water resources are saved.
Description
Technical field
The utility model relates to a kind of counter-infiltration system.
Background technology
Reverse osmosis technology is a kind of comparatively widely at present pure water preparation technology, its principle is under the effect that is higher than solution osmotic pressure, by pellicle impurity and moisture are left, reverse osmosis technology can effectively be removed dissolved salts in the water, colloid, microorganism, organic matter etc.
After the reverse osmosis unit operation,, easily cause the stifled corrosion of dirt of reverse osmosis membrane owing to have dense water in the system, thus need the reverse osmosis unit low-pressure washing, with the discharging of the water after the flushing; Traditional reverse osmosis equipment as low-pressure washing water, has increased cost and energy consumption with the pure water in the pure water case, has wasted a large amount of pure water resources; Under counter-infiltration system initial operating stage or other situations, the water quality of producing water does not reach the pure water standard, but this part water has passed through reverse-osmosis treated, organic matter and salinity in the water reduce greatly, water quality is limpid, such water is called as time pure water, will directly discharge according to traditional approach, has wasted water resource.
The utility model content
The technical problem that the utility model solves provides a kind of saving type RO system that utilizes time pure water rinsing reverse osmosis unit.
The utility model solves its technical problem and adopts following technical scheme: a kind of saving type RO system, comprise reverse osmosis unit, pure water case and inferior pure water case, the delivery port of described reverse osmosis unit is provided with water-supply-pipe, described water-supply-pipe connects described pure water case and time pure water case, described water-supply-pipe is provided with and flows to switching valve, the described switching valve that flows to is led the selection direction of flow according to the fluid electricity in the water-supply-pipe, is provided with the flush loop of cleaning reverse osmosis unit between the water inlet of described pure water case and reverse osmosis unit.
Further technical scheme is: the described switching valve that flows to comprises triple valve and PLC controller, and described water-supply-pipe connects the delivery port of described reverse osmosis unit, described pure water case and inferior pure water case respectively by described triple valve.
Further technical scheme is: described flush loop is provided with flushing pump.
Further technical scheme is: described flush loop is provided with motor-driven valve.
The beneficial effects of the utility model are: flow to switching valve and can when reverse osmosis unit is stopped transport, utilize collected inferior pure water according to current direction pure water case in the conductance control valve body of water body in the water-supply-pipe or inferior pure water case, reverse osmosis unit is washed; On the one hand avoided dense water to remain in the reverse osmosis unit, and most of organic matter and salinity are removed in the inferior pure water, water quality is better, and reverse osmosis unit has been played protective effect, has prolonged the service life of reverse osmosis unit; On the other hand, wash, do not need to consume again a large amount of pure water rinsing, both made full use of inferior pure water, reduced the consumption of pure water again, saved great amount of water resources with time pure water.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
With reference to figure 1, shown in a kind of saving type RO of the utility model system, comprise reverse osmosis unit 1, pure water case 2 and inferior pure water case 3, be connected with water-supply-pipe 41 on the delivery port of described reverse osmosis unit 1, described pure water case 2 is connected along water-supply-pipe 41 water delivery directions successively with time pure water case 3, be provided with in the junction of described water-supply-pipe 41 and pure water case 2 and flow to switching valve 42, the described switching valve 42 that flows to can be led the control fluid to pure water case 2 or inferior pure water case 3 according to the electricity of fluid in the water-supply-pipe 41, is provided with the flush loop 51 of cleaning reverse osmosis unit between the water inlet of inferior pure water case 3 and reverse osmosis unit 1.
A kind of preferred, the described switching valve 42 that flows to comprises triple valve and PLC controller, described water-supply-pipe 41 connects the delivery port of described reverse osmosis unit 1, described pure water case 2 and inferior pure water case 3 respectively by described triple valve 42, and described PLC controller is provided with the display screen that shows electric conductivity value; The electricity of PLC controller test fluid leads whether meet the pure water standard, controls the direction of flow in the triple valve automatically; When water quality does not reach the pure water standard, time pure water case of the direction of flow in the triple valve; When water quality reaches the pure water standard, the direction of flow pure water case in the triple valve.
Flushing reverse osmosis unit 1 needs enough hydraulic pressure, provides power in order to give the water in the flush loop 51, is provided with the flushing pump 52 of supercharging on flush loop.
Also be provided with motor-driven valve 53 on the above-mentioned flush loop 51, the current direction reverse osmosis unit 1 when motor-driven valve 53 is opened in the flush loop, motor-driven valve 53 stops to wash reverse osmosis unit when cutting out.
During described saving type RO system works: under counter-infiltration system initial operating stage or other situations, reverse osmosis produced water water quality does not reach the pure water standard and forms time pure water, automatically control by the PLC controller, this part time pure water is flowed to time pure water case by triple valve; When water quality reached the pure water standard, pure water entered the pure water case by triple valve; When reverse osmosis unit is out of service, utilize the inferior pure water in time pure water case to wash reverse osmosis unit by flush loop, extrude the dense water in the reverse osmosis unit.
Those skilled in the art can make various changes and distortion to the utility model after knowing principle of the present utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
