Shown in composition graphs 1, pretreatment unit 10 comprises the cotton filter core 11 of the PP connected successively and active carbon filter core 12, the cotton filter core 11 of PP is connected with former water interface, first a various granule foreign in former water is filtered, active carbon filter core 12 is connected to the water side of the cotton filter core 11 of PP, there is the effect of filtering with purification, effectively can remove the impurity such as the organism in water.
As shown in Figure 1, first water purification branch road has been arranged in series carbon-point filter core or uf processing unit 20, i.e. water cleaning systems of the present invention, two independent water purification branch roads are split up into after pretreatment unit 10, first water purification branch road (in Fig. 1 shown in label B) is purified pretreated former water further by carbon-point filter core or uf processing unit 20, and from discharging device water outlet, be purified the domestic water that grade is relatively low.Second water purification branch road (in Fig. 1 shown in label A) is purified pretreated former water further by reverse-osmosis treated unit 30, and from discharging device water outlet, is purified grade relatively high, the pure water that can directly drink.Also namely water cleaning systems of the present invention is worked alone by first, second water purification branch road, clean level different two kinds can be provided to purify waste water, and compared to existing technology, because the second water purification branch road is no longer by carbon-point filter core or uf processing unit 20, effectively can reduce the treatment capacity of carbon-point filter core or uf processing unit 20, extend its working hour, thus improve the life-span of whole water cleaning systems.
Preferably, water cleaning systems also comprises the first-class gauge 40 be arranged in series on the first water purification branch road, and add up the water yield of the first water purification branch road (i.e. domestic water branch road), the life-span for each water purification unit of the first water purification branch road reminds.Usually, first-class gauge 40 is arranged on the downstream of carbon-point filter core or uf processing unit 20, and traffic statistics are more accurate.
More preferably, according to the difference of raw water quality, carbon-point filter core or uf processing unit 20 can be chosen as carbon-point filter core or ultra-filtration element, and particularly, if raw water quality contents of residual chlorine is high, carbon-point filter core or uf processing unit 20 can use carbon-point filter core; If raw water quality colloidal content is high, carbon-point filter core or uf processing unit 20 can use ultra-filtration element; This system can select filter core flexibly according to water quality, has universality, extends lifetime of system.
Shown in composition graphs 1, the water that stabilized pressure pump 70 exports enters reverse-osmosis treated unit 30, and in pipeline, the effect of the first reverse checkvalve 33 is the aqueous refluxs prevented in pipeline.Water cleaning systems also comprises scouring electromagnetic valve 32, the entrance end of scouring electromagnetic valve is communicated with the dense water out of reverse-osmosis treated unit 30, the exit end of scouring electromagnetic valve is communicated with discharge of wastewater mouth, and scouring electromagnetic valve 32 is in normally off, is in opened condition when performing flushes instructions.
Concentrate recirculation branch road comprises the current-limiting apparatus 34 of series connection mutually, and the import of current-limiting apparatus 34 is communicated with the dense water out of reverse-osmosis treated unit 30, and the outlet of current-limiting apparatus 34 is connected by threeway with the water-in of stabilized pressure pump 70.Namely a dense water part for reverse-osmosis treated unit 30 is drained through scouring electromagnetic valve, and another part is back to before stabilized pressure pump 70 through current-limiting apparatus 34, again purifies through reverse-osmosis treated unit 30, improves the rate of recovery, can effectively economize on water.In addition, as the mode of the former water of reverse osmosis membrane after the present invention adopts the dense water of a part of reverse osmosis membrane of backflow to mix with pretreated water, namely pretreated water just enters reverse osmosis membrane after diluting the dense water of reverse osmosis membrane, compare in the prior art, direct control waste water ratio electromagnetic valve improves the rate of recovery, effectively can improve the raw water quality of reverse osmosis membrane, slow down the pollution of reverse osmosis membrane, extend the life-span of reverse osmosis membrane.
Preferably, water cleaning systems also comprises and is arranged in series at the second water purification branch road and is positioned at the post-processing unit 80 in reverse-osmosis treated unit 30 downstream, and is arranged on the water cell 90 between post-processing unit 80 and reverse-osmosis treated unit 30.Namely the product water of reverse-osmosis treated unit 30 supplies user through post-processing unit 80, or stores through water cell 90, then flows through post-processing unit 80 and supply user.
Post-processing unit 80 generally adopts composite filter element, and composite filter element mainly comprises carbon rod and ultra-filtration membrane filtrate, stores further the product water after for some time in the product water of process reverse-osmosis treated unit 30 and water tank 91, finally reaches and remove the effect such as bacterium, peculiar smell.
Water cell 90 comprises the water tank 91 and pressure-detecting device 92 that can bear certain pressure, pressure-detecting device 92 mainly detects the water pressures on this water route, and control the entering water electromagnetic valve 50 of preprocessing part, when this branch road hydraulic pressure declines, entering water electromagnetic valve 50 is opened, stabilized pressure pump 70 operates, system water.When this branch road hydraulic pressure raises, entering water electromagnetic valve 50 is closed, and stabilized pressure pump 70 shuts down, and system stops water processed.
Composition graphs 1 illustrates the principle of work of water cleaning systems of the present invention.
In water inlet system working process, because pretreatment unit 10 (the cotton filter core 11 of PP and active carbon filter core 12) is in scavenging process, water amount may be caused not enough because of abnormal conditions, if if now the second water purification branch road is also at water processed, due to the suction force effect of stabilized pressure pump 70, the water and air of the first water purification branch road etc. can be sucked the second water purification branch road, if the air sucked reaches certain capacity, may cause in stabilized pressure pump 70, occurring tired gas phenomenon, now stabilized pressure pump 70 suction makes descaling line pressure between entering water electromagnetic valve and stabilized pressure pump 70 produce unusual fluctuations, and make entering water electromagnetic valve 50 be subject to the frequent impact of fluctuation hydraulic pressure, entering water electromagnetic valve now may be made to send abnormal sound.In addition, the dense water that reverse-osmosis treated unit 30 flows out is back to the front end of stabilized pressure pump 70 by concentrate recirculation branch road, also can there is certain hydraulic pressure herein and clash into fluctuation, pipeline between entering water electromagnetic valve and stabilized pressure pump 70 also may be made to occur abnormal shake or entering water electromagnetic valve misoperation.Between entering water electromagnetic valve and stabilized pressure pump 70, increase a check valve 60, ensure that current can only flow to stabilized pressure pump 70 from entering water electromagnetic valve, solve the abnormal water pressure fluctuations that stabilized pressure pump 70 grade produces, the flow-reversing impingement of entering water electromagnetic valve is affected.And then ensure that entering water electromagnetic valve and the steady running of stabilized pressure pump 70 in lifetime, effectively can ensure the work-ing life that device runs.
