Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, full automatic control saving type RO water machine described in the utility model comprises reverse osmosis membrane filt 8, and reverse osmosis membrane filt 8 is provided with water inlet, pure water outlet and wastewater outlet.Reverse osmosis membrane filt 8 tap water can be isolated the pure water molecule and with the waste water of impurity, its principle is prior art, is not described in detail.Described wastewater outlet is connected to the waste water proportional valve 15 that is in parallel and is connected waste water proportional valve 15 with scouring electromagnetic valve and connects the water inlet of reverse osmosis membrane filts 8; scouring electromagnetic valve 16 connects water port; wastewater outlet is provided with the TDS on-line measuring device 14 that can detect waste water TDS value; TDS on-line measuring device 14 is connected to two-position controller 19; two-position controller 19 and waste water proportional valve 15; scouring electromagnetic valve 16 joins; when described TDS on-line measuring device 14 detects waste water TDS value and surpasses reverse osmosis membrane filt 8 and can tolerate maximum value; two-position controller 19 control scouring electromagnetic valves 16 are opened; waste water proportional valve 15 is closed; scouring electromagnetic valve 16 is opened draining; allow overstandard waste water discharge fast; realize the auto-flushing of reverse osmosis membrane, protection also prolongs the reverse osmosis membrane life-span.When the waste water TDS value that detects is lower than reverse osmosis membrane filt 8 and can tolerates maximum value, two-position controller 19 control waste water proportional valves 15 are opened, scouring electromagnetic valve 16 is closed, the waste water that can enable to utilize so repeatedly circulates through reverse osmosis membrane filt, produces to greatest extent pure water.
The water inlet of described reverse osmosis membrane filt 8 connects municipal water intake ball valve 1, is connected to successively accurate filter 2, low-voltage protective switch 3, the first activated charcoal filter 4, the second activated charcoal filter 5, entering water electromagnetic valve 6, voltage-regulation voltage-stabilization pump 7 between municipal water intake ball valve 1 and the water inlet.The effect of the first activated charcoal filter 4, the second activated charcoal filter 5 is the heterochromatic peculiar smell that reduce in raw water turbidity, the planar water, reach reverse osmosis membrane work enter water condition.
The outlet of described waste water proportional valve 15 is connected to waste water reverse checkvalve 17, and described waste water reverse checkvalve 17 is connected between municipal water intake ball valve 1 and the accurate filter 2 by backwater threeway 18.
The pure water outlet of described reverse osmosis membrane filt 8 connects the special-purpose tap 13 of pure water, is connected to successively pure water reverse checkvalve 9, high voltage protective switch 10, pure water pressure pot 11, Postposition carbon filter 12 between the special-purpose tap 13 of pure water outlet and pure water.So the effect of pure water pressure pot 11 is to collect to isolate pure water in the reverse osmosis membrane filt also with in the daily life.
Principle of work of the present utility model:
The utility model uses 24V direct current transformation power supply.
Open municipal water intake ball valve 1, the municipal tap water enters accurate filter 2, the first activated carbon filtration 4 and the second activated charcoal filter 5 successively, with iron rust, the grains of sand, colourity, the chlorine residue of filtering and absorption tap water.When the intake pressure of tap water during more than or equal to 0. 08MPa, low-tension switch 3 is connected the direct current transformation power supply, entering water electromagnetic valve 6 adhesives, tap water process entering water electromagnetic valve 6 through accurate filter 2, the first activated charcoal filter 4 and 5 filtrations of the second activated charcoal filter, voltage-regulation voltage-stabilization pump 7 with stable water pressure at 0.8～0.9MPa, in the input reverse osmosis membrane filt 8, in reverse osmosis membrane filt, isolate the pure water molecule and with the waste water of impurity.
Pure water from reverse osmosis membrane filt 8 out after, in pure water reverse checkvalve 9 entered pure water pressure pot 11, when pure water pressure pot 11 full waters and when producing about 0. 2～0. 25MPa pressure, high-voltage switch gear 10 disconnected the direct current transformation power supplys, all systems of complete machine stop for the direct current transformation power supply, and complete machine quits work; When the user opens the special-purpose tap 13 of pure water, pure water flows out certain hour, and when pressure pot pressure was lower than 0.1MPa, high-voltage switch gear 10 was connected, and all systems of complete machine connect direct current transformation power supplys and rework.
Waste water from reverse osmosis membrane filt 8 out after, through TDS on-line measuring device 14, when waste water TDS value claims it is tatal dissolved solids less than or equal to English of 1200PPM(TDS, Chinese translation is total dissolved solid, unit is mg/litre, english abbreviation PPM) time, waste water returns through waste water proportional valve 15, waste water reverse checkvalve 17 and backwater threeway 18, recycles with the tap water mixed cycle; When waste water TDS value during greater than 1200PPM, scouring electromagnetic valve 16 is opened 15-30 second, and waste water is fast by scouring electromagnetic valve 16, and high pressure and the water that flows out fast have self-cleaning and washing action to reverse osmosis membrane, can protect and prolong the reverse osmosis membrane life-span.
The utility model can be realized cycling utilization of wastewater and prolong the reverse osmosis membrane life-span, be feasible according to former water analysis.From water quality analysis, the different TDS values that are from waste water of pure water, the waste water that does not reach before the highest use value of reverse osmosis membrane just can recycle, does not affect the water quality of pure water.Municipal tap water such as present Guangzhou, its TDS value is about 90PPM, separation through reverse osmosis membrane filt 95～98%, its waste water TDS value increasing amount about 25%, be exactly less than 115PPM, after mixing, the tap water that the waste water of 115PPM turns back to entry and 90PPM is lower than 105PPM, the water of 105PPM is about 130PPM through waste water behind the reverse osmosis membrane filt, recycled for multiple times like this, draw by actual computation, waste water is through 20 recycled for multiple times, and waste water TDS value just reaches the 1200PPM upper limit, just discharges unavailable waste water by scouring electromagnetic valve; And when waste-water high-pressure and when flowing out fast, have self-cleaning and washing action to reverse osmosis membrane, the purpose that can reach protection and prolong the reverse osmosis membrane life-span.
The waste water that the utility model produces is to move in the pipeline of sealing, and the design pressure of pipeline is 12MPa, can not produce any untoward reaction in whole internal circulation filtering system.
In a word; although the utility model has exemplified above-mentioned preferred implementation; but should illustrate; although those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
