Brief description of the drawings
Fig. 1 is the structure diagram of the water purifier of a preferred embodiment of the present invention.
Embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
Apply among a scope.
As shown in Figure 1, the water purification of the present embodiment includes reverse osmosis membrane filt 1, pressure pot 2, water purification bypass and flushing
Solenoid valve 4.Water purification bypass is equipped with the first solenoid valve 31 and the first check valve 32, and one end of water purification bypass and pressure pot 2
Water outlet connection, the other end is connected with the raw water inlet 11 of reverse osmosis membrane filt 1；Scouring electromagnetic valve 4 is arranged on reverse osmosis
On the pipeline of the wastewater outlet 12 of film filter 1.
In the present embodiment, water purifier is further included into water passage and backwater path.Into one end of water passage and reverse osmosis membrane mistake
The raw water inlet 11 of filter 1 connects, and the other end is connected with the mouth of a river from the beginning 5, should be equipped with fore filter 61, low pressure into water passage
Switch 62, second solenoid valve 63 and booster pump 64.One end of backwater path is connected with wastewater outlet 12, the other end and prefilter
The water inlet connection of device 61；The backwater path is equipped with the second check valve 71 and throttle valve 72, and backwater path enables waste water maximum
Recycle to limit, in the ideal situation, Net water recoveries can reach 75%.
In the present embodiment, the pure water outlet 13 of reverse osmosis membrane filt 1 passes through the water inlet of the 3rd check valve 81 and pressure pot 2
Mouth connection.Water purifier further includes post-filter 82,83 and the 4th check valve 84 of high-voltage switch gear, the water inlet of post-filter 82
It is connected by 83 and the 4th check valve 84 of high-voltage switch gear with the water outlet of the 3rd check valve 81.The post-filter 82 of the present embodiment
Water outlet flowmeter (not shown) can be also set.
In the present embodiment, water purifier further includes touch-screen (not shown), the touch-screen and the first solenoid valve 31, second
Solenoid valve 63 and scouring electromagnetic valve 4 are electrically connected.Touch-screen is used to set the first solenoid valve, second solenoid valve and scouring electromagnetic valve to open
The time open, closed, so as to according to different quality, set the flushing frequency of reverse osmosis membrane.Certainly, touch-screen can also be realized and set
Set low compress switch, unlatching, the shut-in time of high-voltage switch gear and booster pump.
It should be noted that the flushing frequency (namely three solenoid valves are opened, the time of closing) of the present embodiment is according to original
Hydraulic angle value is calculated, and is understood according to practice, and the principal element of the service life decay of reverse osmosis membrane is the hardness number of raw water
Height, TDS (dissolvability solid amount) values of raw water influence it being not very big, and under normal conditions, raw water it is hard
Degree and TDS value fluctuation range very littles, therefore, the present embodiment determine to rinse frequency by the hardness number of raw water.Specifically, touching
The hardness number of the control panel input raw water of screen, the control system of touch-screen then can calculate flushing automatically according to original water hardness value
Frequency.For example, the touch-screen of the present embodiment can (four kinds of water quality conditions be respectively according to tetra- kinds of water quality conditions of A, B, C, D：A's is hard
Angle value is less than 150ppm, and the hardness number of B is 150ppm-250ppm, and the hardness number of C is 250ppm-350ppm, and the hardness number of D is big
In 350ppm), the flushing frequency of selection control scouring electromagnetic valve, general hardness is bigger, and flushing frequency can be set higher.When reaching
Predetermined time, water purifier are rinsed reverse osmosis membrane, and second solenoid valve 63 is closed at this time, and booster pump 64 is stopped, and first
Solenoid valve 31 and scouring electromagnetic valve 4 are opened at the same time, and the pure water of storage is back to reverse osmosis membrane filt to reverse osmosis in pressure pot 2
Film is rinsed, and after reaching setting washing time, namely is rinsed and is completed, and the first solenoid valve 31 and scouring electromagnetic valve 4 simultaneously close off,
Second solenoid valve 63 is opened, and booster pump 64 is started to work, and water purifier starts water processed again, stores pressure pot during water processed full
Pure water.The water purifier of the present embodiment cleverly using pressure pot water storage function and water-storage pressure (pressure is big in general water butt
In 0.25MPa), reverse osmosis membrane is rinsed by force with pure water, ensures that reverse osmosis membrane carries out removing surface after the completion of water processed, to the greatest extent
The state before water processed is returned to soon, is extended the service life of reverse osmosis membrane, is tested by Experimental comparison, the water purification of the present embodiment
The service life of the reverse osmosis membrane of machine about extends 1 times.
Although the embodiment of the present invention is the foregoing described, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
On the premise of the principle of the present invention and essence, various changes or modifications can be made to these embodiments, but these changes and
Modification each falls within protection scope of the present invention.
