Description

Water-saving electricity-saving reverse osmosis water purifying machine
Technical field
The present invention relates to water-treatment technology field, relate 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.For Freshwater resources today 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 purifications, enter high-pressure pump 3 superchargings, 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-downs, thereby prevents pollutent at the reverse osmosis membrane surface deposition, prolongs the work-ing life of reverse osmosis membrane.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 gradually simultaneously, when pressure rises to set(ting)value, pressure switch 5 actions, 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 actions, 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 actions, the power supply of cut off high pump 3, high-pressure pump 3 is with out of service or can not start, to avoid high-pressure pump 3 anhydrous idle running.Be connected with bypass flush valve 9 than 10 import and export two ends 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 purifications, is water quality water preferably comparatively speaking.
2, heavy, the long operational time of high-pressure pump 3 loads 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 the 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 places 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 outlets, 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-downs after, enter 14 storages of condensed water pressure water storage case.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 actions 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 actions, 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 and the ratio of condensed water water flow roughly meet the relation of 1:3, 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 purifications, enter high-pressure pump 3 superchargings, 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-downs.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 actions, 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 is removed the smell that is brought by rubber inner bag in the water tank 6 that may exist in the water through post active carbon filter core 7 again, 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 actions, 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 high-pressure pump 3 anhydrous idle running.After flush valve 9 is opened, can increase substantially the flow rate of water flow 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.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 purifications, 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, the amount of purified water that provides to the user and mix the proportionlity that the water yield can not followed 1:3.But also there are the following problems for pipeline principle shown in Figure 3:
1. high-pressure pump 3 anhydrous idle running phenomenons can not be stopped, problems such as high-pressure pump weak point in 3 work-ing lifes, 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 exits.When tap water pressure was higher, waste water was raised than the back pressure in 10 exits thereupon, caused the condensed water discharging not smooth, increased the weight of the load of high-pressure pump 3, influenced high-pressure pump 3 and normally moved; When tap water pressure was low, hydraulic pressure was difficult to overcome the filtration resistance of preprocessing filter element 2, makes high-pressure pump 3 ingresss negative pressure may occur, and then caused high-pressure pump 3 anhydrous idle running or frequent start-stop phenomenon to occur, influenced high-pressure pump 3 and normally moved.
To solve the problem that exists in above-mentioned three known technologies simultaneously, the technical breakthrough of still needing.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of water-saving electricity-saving reverse osmosis water purifying machine at the deficiency of above-mentioned prior art present situation, and this water purification machine can be stopped the anhydrous idle running phenomenon of high-pressure pump, high-pressure pump long service life, saves energy, former water use efficiency height, the supplying water in different qualities function can be provided, basic non-wastewater discharge, system is stable and low cost of manufacture.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of water-saving electricity-saving reverse osmosis water purifying machine, and it comprises preprocessing filter element, normal pressure intermediate water tank, high-pressure pump, reverse osmosis filter core and the pure water tank of normal pressure; The import of described high-pressure pump connects the normal pressure intermediate water tank, and the high pressure pump outlet connects the water-in of reverse osmosis filter core, and the water outlet of reverse osmosis filter core connects the pure water tank of normal pressure, and the sewage draining exit of reverse osmosis filter core connects a waste water and than then receives the normal pressure intermediate water tank again; The import of described preprocessing filter element connects tap water, and its outlet connects the normal pressure intermediate water tank; Described normal pressure intermediate water tank is provided with water-level control apparatus and water prode; The pure water tank of described normal pressure is provided with water-level probe; The import and export two ends of described waste water ratio are connected with the bypass flush valve by the hydraulic pipe bypass, and this valve can also can electronicly open and close by manual opening-closing.
The further technical scheme that the present invention adopts is: but the pipeline between described normal pressure intermediate water tank and the high-pressure pump import is provided with the filtration unit of particulate matter and suspended substance in the filtering water, this filtration unit also can be arranged on the normal pressure intermediate water tank water outlet place that is connected with the high-pressure pump import, filtering material in this filtration unit can be a non-woven fabrics, also can be the PP cotton, also can be silk screen.
The technology of the present invention also comprises: the outlet pipeline that pure water and mixing water can be provided to the user is set on normal pressure intermediate water tank and the pure water tank of normal pressure respectively.Described mixing water is meant through the water of preprocessing filter element rough purification and condensed water mixed water the normal pressure intermediate water tank of discharging from reverse osmosis filter core sewage draining exit.The further technical scheme that the present invention adopts is to install small pump respectively on the outlet pipeline of this pure water and mixing water, so that user's water intaking.Like this, water-saving electricity-saving reverse osmosis water purifying machine of the present invention has just been realized the supplying water in different qualities function, and mixing water is as cleaning water, and pure water is as drinkable water.
The technology of the present invention also comprises: the water quality probe is set on the normal pressure intermediate water tank.The further technical scheme of the technology of the present invention is: described water quality probe is conductivity probe or TDS probe.
The technology of the present invention also comprises: acoustic alarm device or light warning device are set in electric control system.

Water-saving electricity-saving reverse osmosis water purifying machine of the present invention is when operation, former water (for example tap water) is after the preprocessing filter element rough purification, enter the normal pressure intermediate water tank, after the high-pressure pump supercharging, enter the reverse osmosis filter core again and make further advanced treatment, enter the pure water tank of normal pressure from the effusive pure water of reverse osmosis filter core water outlet and store, after waste water is than step-down, return the normal pressure intermediate water tank as recirculation water from the condensed water that reverse osmosis filter core sewage draining exit is discharged.
Water level in the pure water tank of normal pressure is controlled by described water-level probe.When the user takes pure water, the water level in the pure water tank will descend gradually, and when water level dropped to the control water level, the high-pressure pump power supply was connected in the water-level probe action, and water purification machine begins to make water; When water level rises to the control water level, the water-level probe action, cut off high pumping source, water purification machine stop to make water.
Water level in the normal pressure intermediate water tank is controlled by water-level control apparatus, and when the user takes mixing water, water level wherein will be lower than the control water level, at this moment water inlet is opened in water-level control apparatus action, so, the TDS concentration of the water in this water tank reduces, thereby guarantees that reverse osmosis system normally moves; When the user stops to take mixing water, water level will rise gradually, and when water level rose to the control water level, into water was closed in the water-level control apparatus action.The further technical scheme of the technology of the present invention is: described water-level control apparatus is float(ing)valve or float-actuated valve.
If the user does not take mixing water for a long time, then the water quality probe TDS concentration that will detect the water in the normal pressure intermediate water tank is higher than set(ting)value down, at this moment system will send sound and light alarm, remind the user to take mixing water, so that the TDS concentration of the water in the normal pressure intermediate water tank is reduced to down below the set(ting)value, reverse osmosis system is normally moved.If the user does not still take mixing water, then the TDS concentration of the water in the normal pressure intermediate water tank will further rise, when rising to set(ting)value, system will be when opening high-pressure pump, open blow-off valve, discharge mixing water (blowdown), when TDS concentration is reduced to down set(ting)value when following, close blow-off valve, normally move with this assurance system.After high-pressure pump and blow-off valve are opened simultaneously, can increase substantially flow velocity, be convenient to wash away the pollutent of reverse osmosis membrane surface deposition, improve the work-ing life of reverse osmosis membrane by the reverse osmosis membrane surface,
Water-saving electricity-saving reverse osmosis water purifying machine of the present invention is regularly opened described bypass flush valve when normal operation.The bypass flush valve can increase substantially the flow velocity 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.
If the water source is anhydrous or preprocessing filter element is stopped up, then anhydrous in the normal pressure intermediate water tank, described water prode will detect anhydrous signal this moment, this signal is used for the power supply of cut off high pump, make high-pressure pump out of service or can not start, thereby can thoroughly stop anhydrous idle running of high-pressure pump and frequent start-stop phenomenon, prolong the work-ing life of high-pressure pump.
Because the exit end of described waste water ratio and the water outlet of reverse osmosis filter core connect normal pressure intermediate water tank and the pure water tank of normal pressure respectively, and the normal pressure water tank can guarantee that the water tank internal pressure is always normal pressure, so high-pressure pump steady load of water-saving electricity-saving reverse osmosis water purifying machine of the present invention, water flow is stable, but the work-ing life but also the saves energy of high-pressure pump not only can have been prolonged, in addition, the manufacturing cost of normal pressure water tank is starkly lower than the manufacturing cost of pressure water tank, and the pure water tank of normal pressure does not have rubber smell pollution pure water, just do not need the post active carbon filter core yet, so system's manufacturing cost obviously descends.And existing known technology adopts the pressure water storage case, and load can be increasing when this just caused the high-pressure pump operation, both had a strong impact on the work-ing life of high-pressure pump, wastes electric energy again; In addition, the manufacturing cost of pressure water storage case is higher and the post active carbon filter core need be set, so the system cost height.
The beneficial effect of the technology of the present invention is: can stop anhydrous idle running of high-pressure pump and frequent start-stop phenomenon, high-pressure pump long service life, saves energy, former water use efficiency height, supplying water in different qualities function, basic non-wastewater discharge can be provided, system is stable and low cost of manufacture.
