Description

Water-saving electricity-saving reverse osmosis water purifying machine
Technical field
The utility model relates to water-treatment technology field, relates in particular to a kind of water-saving electricity-saving reverse osmosis water purifying machine.
Background technology
Reverse osmosis is a kind of pure water manufacturing technology of comparative maturity, the utilization ratio of the former water of present large-scale reverse osmosis water production apparatus is higher, and the utilization ratio of the former water of small reverse osmosis water making device is lower, especially adopt the equipment of single reverse osmosis filter core, the household reverse osmosis water purifier of mass selling on the market for example, the utilization ratio of water has only 25%, even lower, promptly produces 1m 3Pure water need consume 4m at least 3Tap water.Die young for the present that Freshwater resources are in short supply day by day, this waste is unfortunate really.
Known technology one: Fig. 1 is known typical small reverse osmosis water purification machine pipeline schematic diagram.In conjunction with shown in Figure 1, during equipment system water, former water enters from water intaking valve (1), earlier after preprocessing filter element (2) rough purification, enter high-pressure pump (3) supercharging, and then enter reverse osmosis filter core (4) and make further advanced treatment, pure water flows to pressure water storage case (6) from the water outlet of reverse osmosis filter core (4) and stores.When water tank (6) being set being for solution equipment system water, the pure water water flow is less to require the bigger contradiction of flow can not satisfy the user and fetch water the time.Equipment is in system water, and the sewage draining exit of reverse osmosis filter core (4) has condensed water to continuously outflow, and this condensed water is discarded after waste water is than (10) step-down, thereby prevents pollutent at the reverse osmosis membrane surface deposition, prolongs the work-ing life of reverse osmosis membrane.After high-pressure pump (3) is moved for some time, water level in the water tank (6) can rise gradually, pressure wherein also can rise gradually simultaneously, when pressure rises to set(ting)value, pressure switch (5) action, the power supply of cut off high pump (3), so high-pressure pump (3) is out of service, system stops to make water.When the user need fetch water, Open valve (8), the water in the water tank (6) passes through post active carbon filter core (7) again, so that remove the smell that is brought by rubber inner bag in the water tank (6) that may exist in the water, flows to valve (8) then.Along with fetch water the carrying out of process of user, the pressure in the water tank (6) descends gradually, and when pressure dropped to down set(ting)value, the power supply of high-pressure pump (3) was connected in pressure switch (5) action, opens high-pressure pump (3), and system begins to make water again, and moves in circles with this.When anhydrous or pressure is too low when the water source, pressure switch (11) action, the power supply of cut off high pump (3), high-pressure pump (3) is with out of service or can not start, to avoid the anhydrous idle running of high-pressure pump (3).Be connected with bypass flush valve (9) than the import and export two ends of (10) by the hydraulic pipe bypass at waste water, after flush valve (9) is opened, can increase substantially flow velocity by the reverse osmosis membrane surface, be convenient to wash away the pollutent of reverse osmosis membrane surface deposition, improve the work-ing life of reverse osmosis membrane, it can manually openedly also can be opened automatically.
This reverse osmosis water manufacturing system can effectively prevent reverse osmosis membrane surface deposition pollutent, prolongs the work-ing life of reverse osmosis membrane, and effluent quality is good, and equipment can be accomplished unattended duty, and the user is easy to use.But there are the following problems for this reverse osmosis water manufacturing system:
1, wastes water
Condensed water discharging is constantly arranged during equipment system water, and the emission flow of condensed water is more than 3 times or 3 times of pure water water flow, these water waste like this.So-called condensed water is not dense in fact, and especially when adopting water quality tap water is as former water preferably, situation is all the more so, and these water have all passed through preprocessing filter element (2) rough purification, is water quality water preferably comparatively speaking.
2, heavy, the long operational time of high-pressure pump (3) load not only influences work-ing life but also waste electric energy
During equipment system water, enter pressure water storage case (6) from the effusive pure water of water outlet of reverse osmosis filter core (4).Along with the carrying out of system water process, the pressure in the pressure water storage case (6) can rise gradually.Like this, just raised the back pressure at reverse osmosis filter core (4) water outlet place gradually, made the load of high-pressure pump (3) increase the weight of gradually, carrying out of filtration procedure is more and more difficult, and water flow also can be more and more littler thereupon, and this has just prolonged the working time of high-pressure pump (3) again.Its consequence is not only to influence the work-ing life of high-pressure pump (3) but also waste electric energy.
3, manufacturing cost height
One, from the effusive pure water of reverse osmosis filter core (4) water outlet, the rubber smell in the water tank (6) that is under pressure again pollutes, and in order to eliminate the rubber smell, increases a post active carbon filter core (7) again, thereby makes system cost increase.
Its two, for pressure water storage case (6), on the one hand for pressurized safety, its housing needs enough intensity (housing should be able to bear the pressure of 0.6MPa at least); Enough spaces that stored-gas is used will be left in its inside on the other hand, so that general's hydraulic pressure wherein is to flowing water Valve (8) under gas pressure, this has just reduced the live storage volume of water tank (6).The two has all improved the manufacturing cost of water tank (6).
4. high-pressure pump (3) may be because of anhydrous idle running occurring or frequent start-stop phenomenon is damaged
Along with the carrying out of filtration procedure, preprocessing filter element (2) can be stopped up gradually.In case the preprocessing filter element (2) that the user does not have timely replacing to stop up even then there is water at the water source, can not guarantee the water high pressure supply pump (3) that flow is enough big.Like this, anhydrous idle running or frequent start-stop phenomenon just can appear in high-pressure pump (3) inevitably, thereby cause high-pressure pump (3) to be damaged.For the domestic water purifying machine that the layman uses, the possibility that this phenomenon occurs is quite big.
Known technology two: in order to utilize the condensed water of discharging from reverse osmosis filter core sewage draining exit, people improve pipeline principle shown in Figure 1.Fig. 2 is the reverse osmosis water purification machine pipeline schematic diagram after improving, in conjunction with shown in Figure 2, the condensed water of discharging from reverse osmosis filter core sewage draining exit through waste water than (10) step-down after, enter condensed water pressure water storage case (14) and store.Condensed water in the condensed water pressure water storage case (14) can be used as undrinkable water (water for cleaning) and can emit by valve (12).The effect of flush valve (9) is identical with Fig. 1, promptly is used to wash the settling on reverse osmosis membrane surface, improves the work-ing life of reverse osmosis membrane.
Pressure switch (13) is installed on the suction culvert of condensed water pressure water storage case (14), is used to control the start-stop of high-pressure pump.When the pressure in the condensed water pressure water storage case (14) rose to set(ting)value, pressure switch (13) action disconnected the high-pressure pump power supply, and system stops to make water.When the user took condensed water, the water in the water tank (14) can be emitted by valve (12).Along with the carrying out of water intaking process, the pressure in the water tank (14) descends gradually, and when pressure dropped to set(ting)value in the water tank (14), the high-pressure pump power supply was connected in pressure switch (13) action, and system can begin to make water.
Other parts in the pipeline principle shown in Figure 2 are identical with Fig. 1.
Compared to Figure 1, the advantage of pipeline principle shown in Figure 2 is: water purification machine is realized supplying water in different qualities function (condensed water is as cleaning water, and pure water is as drinkable water), and all former water all obtained utilization, has solved the problem of wasting water.But also there are the following problems for pipeline principle shown in Figure 2:
High-pressure pump work-ing life short, waste electric energy, can not stop the anhydrous idle running of high-pressure pump and problems such as frequent start-stop phenomenon, manufacturing cost height still exist, and, make manufacturing cost further rise owing to increased condensed water pressure water storage case (14).
2. system's fluctuation of service
Because the pure water water flow of reverse osmosis filter core roughly meets 1: 3 relation with the ratio of condensed water water flow, this just requires the user to use the amount of pure water and uses the amount of condensed water also will meet this proportionlity, and system could long-time stable normal operation.To fetch water be at random and reality is the user, can not just in time meet this proportionlity, and this is with regard to occurring inevitably when one of them water tank is anhydrous and another water tank pressure high requirement stops to make the phenomenon of water.In other words, the user may certain the time fetch water, and anhydrous desirable in this moment corresponding water tank.
Known technology three: in order to utilize the condensed water of discharging from reverse osmosis filter core sewage draining exit, people have carried out another improvement to pipeline principle shown in Figure 1.Fig. 3 is the reverse osmosis water purification machine pipeline schematic diagram after improving, in conjunction with shown in Figure 3, former water enters water-water jet (16) through water intaking valve (1), again after preprocessing filter element (2) rough purification, enter high-pressure pump (3) supercharging, and then enter reverse osmosis filter core (4) and make further advanced treatment, pure water flows to pressure water storage case (6) from the water outlet of reverse osmosis filter core (4) and stores.Simultaneously, continuously outflow condensed water from the sewage draining exit of reverse osmosis filter core (4), this partial concentration water flows back to water-water jet (16) through waste water after than (10) step-down.After high-pressure pump (3) was moved for some time, the water level in the water tank (6) can rise gradually, and pressure wherein also can rise thereupon gradually simultaneously.When pressure rises to set(ting)value, pressure switch (5) action, the power supply of cut off high pump (3), so high-pressure pump (3) is out of service, system stops to make water.When the user need take pure water, twist the pure water water outlet handle of double-handle depotition cock (17), then the water in the water tank (6) passes through post active carbon filter core (7) again and removes the smell that is brought by rubber inner bag in the water tank (6) that may exist in the water, emits from double-handle depotition cock (17).Along with fetch water the carrying out of process of user, the pressure in the water tank (6) descends gradually, and when pressure dropped to down set(ting)value, the power supply of high-pressure pump (3) was connected in pressure switch (5) action, opens high-pressure pump (3), and system begins to make water again, and moves in circles with this.When the water source is anhydrous, pressure switch (15) action, the power supply of cut off high pump (3), high-pressure pump (3) is with out of service or can not start, to avoid the anhydrous idle running of high-pressure pump (3).Flush valve (9) can increase substantially the flow rate of water flow by the reverse osmosis membrane surface after opening, and is convenient to wash away the pollutent of reverse osmosis membrane surface deposition, improves the work-ing life of reverse osmosis membrane, and it can manually openedly also can be opened automatically.When the user need take cleaning water, twist the mixing water water outlet handle of double-handle depotition cock (17), then tap water after preprocessing filter element (2) rough purification, flows out from double-handle depotition cock (17) through water-water jet (16) again.Along with the carrying out of this process, the TDS concentration of water reduces gradually in the water-water jet (16).
Compare with Fig. 2, the advantage of pipeline principle shown in Figure 3 is: the whole advantages that not only possess pipeline principle shown in Figure 2, and can guarantee: as long as the water source has water and preprocessing filter element (2) not to stop up, whenever all can provide pure water or mixing water, because in native system, can not follow 1: 3 proportionlity to the amount of purified water and the mixing water yield that the user provides.But also there are the following problems for pipeline principle shown in Figure 3:
1. the anhydrous idle running phenomenon of high-pressure pump (3) can not be stopped, problems such as high-pressure pump (3) weak point in work-ing life, waste electric energy can not be solved.
2. system's fluctuation of service
Waste water is subjected to the influence of tap water pressure than the pressure in (10) exit.When tap water pressure was higher, waste water was raised than the back pressure in (10) exit thereupon, caused the condensed water discharging not smooth, increased the weight of the load of high-pressure pump (3), influenced the normal operation of high-pressure pump (3); When tap water pressure is low, hydraulic pressure is difficult to overcome the filtration resistance of preprocessing filter element (2), make high-pressure pump (3) ingress negative pressure may occur, and then cause high-pressure pump (3) anhydrous idle running or frequent start-stop phenomenon to occur, influence the normal operation of high-pressure pump (3).
To solve the problem that exists in above-mentioned three known technologies simultaneously, the technical breakthrough of still needing.
