Embodiment
(embodiment 1)
See Fig. 1, the water-saving reverse osmosis water purifier of the present embodiment, comprises flush valve 1, large flow throttle valve 2, preprocessing filter element 3, return line 4, water intaking valve 5, water activating device 6, low-tension switch 7, topping-up pump 8, low discharge throttling valve 9, reverse-osmosis treated device 10, high-voltage switch gear 11, post active carbon filter core 12, pure water depotition cock 13 and pressure water storage tank 14.
The import of preprocessing filter element 3 is communicated with water source, and its outlet is communicated with the import of reverse-osmosis treated device 10.Topping-up pump 8 is arranged in the suction culvert of reverse-osmosis treated device 10.One end of return line 4 is communicated with the condensed water outlet of reverse-osmosis treated device 10, and the other end is communicated with the suction culvert of topping-up pump 8.Large flow throttle valve 2 is arranged on return line 4.The import of flush valve 1 is communicated with the condensed water outlet of reverse-osmosis treated device 10, and its outlet is communicated with the suction culvert of topping-up pump 8.The import of low discharge throttling valve 9 is communicated with the suction culvert of reverse-osmosis treated device 10 or condensed water outlet pipeline or the return line of reverse-osmosis treated device 10, and it exports emptying.Water intaking valve 5 is arranged in the suction culvert of reverse-osmosis treated device 10.Water activating device 6 is arranged on the suction culvert of preprocessing filter element 3.Water activating device 6 is electromagnetic field treater or magnetic field processor, and its inner water (flow) direction is vertical with the magnetic line of force direction in electromagnetic wave propagation direction or magnetic field.
The pure water outlet of reverse-osmosis treated device 10 is communicated with high-voltage switch gear 11 and pressure water storage tank 14 successively.Pressure water storage tank 14 is communicated with pure water depotition cock 13 by post active carbon filter core 12.High-voltage switch gear 11 is the electric switches that opened and closed by hydraulic pressure control.High-voltage switch gear 11 opens or closes topping-up pump 8 automatically according to the pressure in pressure water storage tank 14, open topping-up pump 8 water processed when pressure water storage tank 14 internal pressures are lower than set(ting)value that is:; When pressure water storage tank 14 internal pressures are not less than set(ting)value, close topping-up pump 8 and stop water processed, or open flush valve 1 and rinse and close again topping-up pump 8 after for some time and stop water processed.
Low-tension switch 7 is arranged in the suction culvert of topping-up pump 8.Low-tension switch 7 is the electric switches that opened and closed by hydraulic pressure control.Can low-tension switch 7 open topping-up pump 8 according to whether lack of water is determined at water source, prevents the anhydrous idle running of topping-up pump 8.That is: when source pressure is very low, system can be thought water source lack of water, forbids that topping-up pump 8 starts; When hydraulic pressure is not less than set(ting)value, system thinks that there is water at water source, and topping-up pump 8 can start.
In the present embodiment, preprocessing filter element 3 is comprised of two portions.Pipeline between two portions of one end connection preprocessing filter element 3 of return line 4.A part for topping-up pump 8, reverse-osmosis treated device 10, return line 4 and preprocessing filter element 3 forms circulation line.
Certainly, one end of return line also can be communicated with suction culvert or the outlet pipeline of preprocessing filter element 3.
The import of low discharge throttling valve 9 is communicated with the suction culvert of reverse-osmosis treated device 10, rather than is communicated with the condensed water outlet pipeline of reverse-osmosis treated device 10, and setting can effectively prevent that low discharge throttling valve 9 from stopping up like this, the reasons are as follows:
1., in order to obtain very little flow, throttle orifice in low discharge throttling valve 9 or the diameter of choker-line are very little, be easy to be stopped up by solid-state small particle, and the scale forming matter that in the condensed water outlet pipeline of reverse-osmosis treated device 10, existence frequently may come off from reverse osmosis membrane, i.e. solid-state finely ground particle substance.
2. the condensed water, in reverse-osmosis treated device 10 condensed water outlet pipelines, soluble solid wherein causes content to raise because being concentrated, and fouling tendency increases, thereby easily fouling; And water in reverse-osmosis treated device 10 suction culverts has adding of former water on the one hand, dilution to some extent to a certain extent; On the other hand, the condensed water of backflow is processed through overactivation and preprocessing filter element 3 again, and its fouling tendency obviously declines, and the particulate solid in water also pretreated filter core 3 is removed.
Be arranged on the large flow throttle valve 2 on return line 4, although the water therefrom flowing through may contain solid-state small particle and fouling tendency is larger, but the flow of return line 4 is very large, this just requires the diameter of throttle orifice in large flow throttle valve 2 or choker-line also correspondingly larger, the not susceptible to plugging reason of macropore is well-known, so the large flow throttle valve 2 on return line 4 is difficult for stopping up.
During filtration, former water is after preprocessing filter element 3 is processed, flow into reverse-osmosis treated device 10 and carry out advanced treatment, the pure water feed pressure water tank 14 flowing out from the pure water outlet of reverse-osmosis treated device 10 stores, the condensed water flowing out from the concentrated mouth of a river of reverse-osmosis treated device 10 is all back to the import of water activating device 6 or is back to preprocessing filter element 3 or the import of part preprocessing filter element 3 mixes with former water through large flow throttle valve 2 from return water pipe 4, after water activating device 6 and/or preprocessing filter element 3 processing, flows into reverse-osmosis treated device 10 again; 9, the low discharge throttling valve that its water-in is communicated with reverse-osmosis treated device 10 suction culverts with basicly stable flow at the mixing water that continues discharge condensed water and former water, so that the concentration that makes the water in circulation line by limit value within the specific limits; When pressure water storage tank 14 internal pressures reach after set(ting)value, be contained in high-voltage switch gear 11 take-offs in pure water pipeline; At this moment, open flush valve 1, under the dynamic action of topping-up pump 8, flow velocity in circulation line is very fast, wash away the former water side surface of reverse osmosis membrane, the obstruction material that is deposited on reverse osmosis membrane surface during by water processed just now strips down from reverse osmosis membrane, the water permeability of reverse osmosis membrane is restored, and contain stop up material wash-down water after flush valve 1, enter preprocessing filter element 3 or 3 processing of part preprocessing filter element, the water-in of getting back to again reverse-osmosis treated device 10 after removal tamper wherein, rinses reverse osmosis membrane again; Circulation flushing is after for some time like this, and topping-up pump 8 power-off are closed, flush valve 1 and water intaking valve 5 are also closed, and system is in holding state.During user's water, open pure water depotition cock, the water in pressure water storage tank 14 flows to pure water depotition cock 13 after post active carbon further improves mouthfeel; Along with emitting of pressure water storage tank 14 interior pure water, pressure water storage tank 14 internal pressures constantly decline, and when the hydraulic pressure in pressure water storage tank 14 is reduced to set(ting)value, high-voltage switch gear 11 resets, and opens water intaking valve 5 and topping-up pump 8, and system starts water processed.System is automatically moved like this and is stopped.
