The naked eyes visible such as suspension, iron rust in water, and chlorine residue, peculiar smell and organic pollution, obtaining can be with
For wash vegetables, the life purified water to wash the dishes, this purified water is flowed through water pipeline 22 by water purification delivery port 20
Go out.Water after the first preprocessing filter element 5 and the filtering of the second preprocessing filter element 7 enters back into counter-infiltration (RO)
Filter core 15 is further purified, and filtering out the bacterium in water, virus, heavy metal and organic matter etc. has
Evil material, obtains the pure water that can directly drink, pure water is flowed out through pure water delivery port 8 for drinking.And with
This simultaneously, then a part through return line 19 is back to supercharging to caused concentrated water during pure water is prepared
The delivery port of pump 18, another part concentrated water are discharged through concentrated water discharge outlet 13, reach the purpose of saving water resource.
Embodiment 3
Reference picture 2, the big flux with dual pump apparatus, the water purification of low waste water reverse osmosis water purifier described in the present embodiment
Method, methods described include：
S1, running water is switched to the water inlet of anti-penetration water purifier, starts the water purifier；
S2, water of the running water after the first preprocessing filter element 5 of water purifier and the filtering of the second preprocessing filter element 7 enter again
Enter the purification of counter-infiltration (RO) filter core 15 and prepare pure water；
Caused concentrated water includes two parts during pure water is prepared, and a part is returned through return line (19)
The delivery port of booster pump 18 is flow to, another part concentrated water is expelled directly out through concentrated water discharge outlet 13.
(1) low tension switch 2 and water inlet are provided between the preprocessing filter element 5 of water inlet 1 and first of water purifier
Magnetic valve 3, when the intake pressure that water purifier measures is less than preset value A, low tension switch 2 is triggered to water purification
The electric-controlled plate of device sends low-voltage signal, and electric-controlled plate starts water insufficiency alarm device after receiving low-voltage signal, meanwhile,
Disconnect entering water electromagnetic valve 3 and close booster pump 18, protect water purifier main body, and substantially reduce leak risk.
(2) high-voltage switch gear 9 is set at the pure water delivery port 8 of water purifier, when the water outlet that high-voltage switch gear 9 measures
When mouth pressure is higher than preset value B, triggering high-voltage switch gear 9 sends high-voltage signal to the electric-controlled plate of water purifier,
After electric-controlled plate receives high-voltage signal, stop the work of counter-infiltration filter core 15, meanwhile, disconnect entering water electromagnetic valve 3
With closing booster pump 18.
(3) when the electric-controlled plate of water purifier receives the signal that water purification delivery port is opened, electric-controlled plate directly controls together
When open entering water electromagnetic valve 3 and water purification magnetic valve 21, under conditions of it need not start booster pump 18, you can system
The life water purification that must be filtered through two-stage preprocessing filter element.
(4) during pure water is prepared, concentrated water part warp caused by the concentrated water end of counter-infiltration filter core 15
Concentrated water combination valve 14 is discharged through concentrated water delivery port 13, and another part by return line 19 then through carrying out concentrated water
Backflow, the concentrated water of backflow enter the delivery port of booster pump 18 by reflux pump 16, with being filtered by the first pretreatment
The preprocessing filter element 7 of core 5 and second is handled and the water purification after the supercharging of booster pump 18 enters counter-infiltration filter core in the lump
15 are filtered.
(4) concentrated water by adjusting the reflux pump 16 being arranged on return line with being arranged on concentrated water outlet 13
Proportioner in combination valve 14, control and directly discharged concentrated water water M from concentrated water outlet 13 and be back to supercharging
Proportionate relationship between the concentrated water water N of the delivery port of pump 18.
Specially：During pure water is prepared, concentrated water part warp caused by the concentrated water end of counter-infiltration filter core 15
Concentrated water combination valve 14 is discharged by concentrated water delivery port 13, and another part then carries out concentrate recirculation by return line 19,
The concentrated water of backflow enters the water inlet of booster pump 18, with passing through the first preprocessing filter element 6 and the second preprocessing filter element 7
Water purification after processing is again introduced into counter-infiltration (RO) filter core 15 through the supercharging of booster pump 18 together and filtered, and leads to
The size for changing auxiliary proportioner in proportioner 16 and concentrated water combination valve 14 is crossed, reaches different water-saving abilities.
Water purification, the preparation of pure water, the reflux cycle of condensed water and discharge of the present invention are all controlled using intelligence
System, water purification or pure water tap need to be only opened when in use, water purifier can automatic running corresponding program.
Water purifier of the present invention has the function of a tractor serves several purposes, even if in the event of a loss of power, can also make
The preparation of water purification is carried out with the water purifier, is specially：Inlet valve and pure water inlet are opened, running water enters
Water purifier, successively after the first preprocessing filter element 5 and the second preprocessing filter element 7 through water purification pipeline from water purification
Outlet outflow.
By using above-mentioned technical proposal disclosed by the invention, following beneficial effect has been obtained：
The 1st, dual pump apparatus is set, by changing proportioner in reflux pump and concentrated water combination valve on return line
It size, can reach the water-saving ability of water purifier《Family expenses and the water saving certification of similar applications reverse osmosis water purifier》》
" leader " of standard economizes on water grade (pure water producing water ratio >=75%), far above generally existing on the market at present
Pure water producing water ratio be 25% anti-penetration water purifier, water conservation significantly.
2. the condensed water after being pressurized by reflux pump through booster pump without being pressurized again, you can into counter-infiltration
(RO) film is filtered, and reduces the specification requirement of booster pump, so as to select the supercharging of more low discharge
Pump, this has obvious advantage for big flux water purifier in the selecting party face of booster pump, while reduces net
The noise of hydrophone complete machine.
