Embodiment
(embodiment 1)
See Fig. 1, the water-saving reverse osmosis water purifier of the present embodiment, comprises flush valve 1, large discharge throttling 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 inlet communication water source of preprocessing filter element 3, the import of its outlet 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 discharge throttling valve 2 is arranged on return line 4.The condensed water outlet of the inlet communication reverse-osmosis treated device 10 of flush valve 1, the suction culvert of its outlet topping-up pump 8.The suction culvert of inlet communication reverse-osmosis treated device 10 of low discharge throttling valve 9 or the condensed water outlet pipeline of reverse-osmosis treated device 10 or return line, 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 the water (flow) direction of its inside 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 opened and closed by hydraulic pressure control.High-voltage switch gear 11 is automatically opened according to the pressure in pressure water storage tank 14 or is closed topping-up pump 8, that is: pressure water storage tank 14 internal pressure opens topping-up pump 8 water processed lower than during set(ting)value; Close topping-up pump 8 when pressure water storage tank 14 internal pressure is not less than set(ting)value and stop water processed, or open after for some time is rinsed in flush valve 1 and close topping-up pump 8 stopping water processed again.
Low-tension switch 7 is arranged in the suction culvert of topping-up pump 8.Low-tension switch 7 is the electric switches opened and closed by hydraulic pressure control.Low-tension switch 7 according to water source, whether can determine open topping-up pump 8 by lack of water, prevents the anhydrous idle running of topping-up pump 8.That is: when source pressure is very low, system can think 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 made up of two portions.Pipeline between two portions of one end connection preprocessing filter element 3 of return line 4.The part composition circulation line of topping-up pump 8, reverse-osmosis treated device 10, return line 4 and preprocessing filter element 3.
Certainly, one end of return line also can be communicated with suction culvert or the outlet pipeline of preprocessing filter element 3.
The suction culvert of the inlet communication reverse-osmosis treated device 10 of low discharge throttling valve 9, instead of the condensed water outlet pipeline being communicated with reverse-osmosis treated device 10, arrange like this and can effectively prevent low discharge throttling valve 9 from blocking, reason is as follows:
1., in order to obtain very little flow, throttle orifice in low discharge throttling valve 9 or the diameter of choker-line very little, be easy to be blocked by small solid particles thing, and there is the scale forming matter that frequently may come off from reverse osmosis membrane in the condensed water outlet pipeline of reverse-osmosis treated device 10, i.e. small solid particles material.
2. the condensed water, in reverse-osmosis treated device 10 condensed water outlet pipeline, soluble solid wherein causes content to raise because being concentrated, fouling tendency increases, thus easily fouling; And the water in reverse-osmosis treated device 10 suction culvert, there is adding of former water on the one hand, dilute to some extent to a certain extent; On the other hand, the condensed water of backflow processes 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 discharge throttling valve 2 on return line 4, although the water flowed therethrough may contain small solid particles thing and fouling tendency is larger, but the flow of return line 4 is very large, this just requires that the diameter of the throttle orifice in large discharge throttling valve 2 or choker-line is also correspondingly larger, the not susceptible to plugging reason of macropore is well-known, so the large discharge throttling valve 2 on return line 4 not easily blocks.
During filtration, former water is after preprocessing filter element 3 processes, flow into reverse-osmosis treated device 10 and carry out advanced treatment, the pure water feed pressure water tank 14 flowed out from the pure water outlet of reverse-osmosis treated device 10 stores, from reverse-osmosis treated device 10 concentrate the mouth of a river flow out condensed water all from return water pipe 4 through large discharge throttling valve 2 be back to water activating device 6 import or be back to preprocessing filter element 3 or part preprocessing filter element 3 import mix with former water, through water activating device 6 and/or preprocessing filter element 3 process after flow 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 culvert is with the mixing water of basicly stable flow at continued emissions condensed water and former water, so that the concentration making the water in circulation line by limit value within the specific limits; After pressure water storage tank 14 internal pressure reaches set(ting)value, be contained in high-voltage switch gear 11 take-off 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 blocking material being deposited on reverse osmosis membrane surface during water processed is just now stripped down from reverse osmosis membrane, the water permeability of reverse osmosis membrane is restored, and the wash-down water containing blocking material is after flush valve 1, enter preprocessing filter element 3 or part preprocessing filter element 3 process, get back to again the water-in of reverse-osmosis treated device 10 after removing tamper wherein, again reverse osmosis membrane is rinsed; Like this after circulation flushing for some time, topping-up pump 8 power-off closedown, 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 improves further after mouthfeel through post active carbon and flows to pure water depotition cock 13; Along with the releasing of pure water in pressure water storage tank 14, pressure water storage tank 14 internal pressure constantly declines, and when the hydraulic pressure in pressure water storage tank 14 is reduced to set(ting)value, high-voltage switch gear 11 resets, and open water intaking valve 5 and topping-up pump 8, system starts water processed.System is automatically run like this and is stopped.
