Description of drawings
Fig. 1 is the structural representation of Automatic Control saving type RO water machine.
The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
As shown in Figure 1, the described Automatic Control saving type RO of the utility model water machine 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 can be isolated running water the waste water of pure water molecule and band impurity, and its principle is a prior art, is not described in detail.Described wastewater outlet is connected to the waste water proportioning valve 15 and scouring electromagnetic valve 16 that is in parallel; Waste water proportioning valve 15 connects the water inlet of reverse osmosis membrane filt 8, and scouring electromagnetic valve 16 connects discharge outlet, and 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 automatic controller 19; Automatic controller 19 joins with waste water proportioning valve 15, scouring electromagnetic valve 16, and when described TDS on-line measuring device 14 detected waste water TDS value and surpasses reverse osmosis membrane filt 8 and can tolerate maximum, automatic controller 19 control scouring electromagnetic valves 16 were opened, waste water proportioning valve 15 cuts out; Scouring electromagnetic valve 16 is opened draining; Let overstandard waste water discharge fast, realize the automatic flushing of reverse osmosis membrane, protection also prolongs the reverse osmosis membrane life-span.When detected waste water TDS value is lower than reverse osmosis membrane filt 8 and can tolerates maximum; Automatic controller 19 control waste water proportioning 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 pure water to greatest extent.
The water inlet of described reverse osmosis membrane filt 8 connects municipal water intake ball valve 1, is connected to accurate filter 2, low-voltage protective switch 3, first active carbon filter 4, second active carbon filter 5, entering water electromagnetic valve 6, voltage-regulation voltage-stabilization pump 7 between municipal water intake ball valve 1 and the water inlet successively.The effect of first active carbon filter 4, second active carbon filter 5 is the heterochromatic peculiar smell that reduce in raw water turbidity, the adsorbed water, reach reverse osmosis membrane work go into water condition.
The outlet of described waste water proportioning valve 15 is connected to waste water non-return valve 17, and described waste water non-return valve 17 is connected between municipal water intake ball valve 1 and the accurate filter 2 through 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 pure water non-return valve 9 successively, high voltage protective switch 10, pure water pressure pot 11, post active 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.
The operation principle of the utility model:
The utility model uses 24V direct current transformation power supply.
Open municipal water intake ball valve 1, the municipal tap water gets into accurate filter 2, first activated carbon filtration 4 and second active carbon filter 5 successively, with iron rust, the grains of sand, colourity, the chlorine residue of filtering with the absorption running water.When the intake pressure of running 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, the running water that filters through accurate filter 2, first activated carbon filtration 4 and second active carbon filter 5 are through entering water electromagnetic valve 6, 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 waste water of pure water molecule and band impurity.
After pure water comes out from reverse osmosis membrane filt 8; In pure water non-return valve 9 got into pure water pressure pots 11, when pure water pressure pot 11 full waters and when producing about 0.2 ~ 0.25MPa pressure, high-voltage switch gear 10 broke off the direct current transformation power supplys; All systems of complete machine stop to supply 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.
After waste water comes out from reverse osmosis membrane filt 8; Through TDS on-line measuring device 14, (the English full name of TDS is tatal dissolved solids, and Chinese translation is a total dissolved solid smaller or equal to 1200PPM when waste water TDS value; Unit is a mg/litre; English abbreviation PPM) time, waste water returns through waste water proportioning valve 15, waste water non-return valve 17 and backwater threeway 18, utilizes with the running water mixing circulation again; When waste water TDS value during greater than 1200PPM, scouring electromagnetic valve 16 was opened 15 ~ 30 seconds, and waste water is fast through scouring electromagnetic valve 16, and high pressure and the water that flows out fast have self-cleaning and flushing 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 that the analysis of the former water of foundation is fully feasible.From water analysis, the different TDS values that are of pure water with waste water, the waste water that does not reach before the highest use value of reverse osmosis membrane just can recycle, does not influence the water quality of pure water.Like the municipal tap water in present Guangzhou, its TDS value is about 90PPM, through the separation of reverse osmosis membrane filt 95 ~ 98%; Its waste water TDS value recruitment is about 25%, is exactly less than 115PPM, is lower than 105PPM after the running water that the waste water of 115PPM turns back to entry and 90PPM mixes; The water of 105PPM is about 130PPM through waste water behind the reverse osmosis membrane filt; So recycled for multiple times draws by Practical Calculation, and waste water is through 20 recycled for multiple times; 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 flushing action, the purpose that can reach protection and prolong the reverse osmosis membrane life-span to reverse osmosis membrane.
The waste water that the utility model produces is in the pipeline of sealing, to move, and the design pressure of pipeline is 12MPa, in whole internal circulation filtering system, can not produce any bad reaction.
In a word; The above-mentioned preferred implementation though the utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of the utility model only if such variation and remodeling have departed from the scope of the utility model.
