Saving type RO membrane water purifier provided by the invention, while ensureing the purification function that reverse osmosis membrane is brought into normal play, by the TDS value of the former water of on-line checkingi, dynamically control wastewater discharge accurately, thus reducing the quantity discharged of waste water, raw wastewater is recycled to greatest extent, and " other " Water usage as user in machine water process is suitable, even can reach the effect that " zero " discharges, thus save valuable water resources.
Accompanying drawing explanation
Fig. 1 is the water purification process schematic diagram of the saving type RO membrane water purifier of the embodiment of the present invention.
Embodiment
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiments of the invention, but the present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar change thereof, all should list protection scope of the present invention in.
As shown in Figure 1, a kind of saving type RO membrane water purifier that the embodiment of the present invention provides, is characterized in that: comprise pre-filtering device 1, topping-up pump 2, TDS detector 3(water dissolution total solids level detector), reverse osmosis membrane filtration assembly 4, two water tap 7, pressure water storage tank 8, bypass magnetic valve 10, backwater throttling valve 9;
Described pre-filtering device is connected in series successively by multiple strainer and forms (being made up of three strainers in this example), the water outlet of pre-filtering device receives the water-in of topping-up pump 2, the water-in of TDS detector 3 receives the water outlet of topping-up pump 2, the water outlet of TDS detector 3 receives the water-in of reverse osmosis membrane filtration assembly 4, and the detection signal output terminal of TDS detector 3 receives the electrical control end of bypass magnetic valve 10;
Two water-ins of described pair of water tap 7 are respectively the first water-in, the second water-in, first water-in of two water tap 7 is connected to one for controlling the pressure switch 6 that topping-up pump runs, and the electrical signal of this pressure switch 6 receives the electrical control end of topping-up pump 2;
The water purification water outlet of described reverse osmosis membrane filtration assembly 4 goes out through one the first water-in that water one-way valve 5 receives pressure water storage tank 8 and two water tap 7, and the condensed water water outlet of reverse osmosis membrane filtration assembly 4 receives two second water-in of water tap 7 and the water-in of backwater throttling valve 9;
The water outlet of described backwater throttling valve 9 receives the water-in of bypass magnetic valve 10, and receives the water-in of pre-filtering device through a backwater check valve 11.
In the embodiment of the present invention, described pair of water tap 7, reverse osmosis membrane filtration assembly 4, TDS detector 3 are prior art, and two water tap refers to the water tap with a water-in and two water-ins.
The water treatment process of the embodiment of the present invention is as follows:
Under the dynamic action of topping-up pump 2, source water enters from the water-in of pre-filtering device 1, water after pre-filtering device 1 filters enters into reverse osmosis membrane filtration assembly 4 by TDS detector 3, two-way is divided into after water purification after reverse osmosis membrane filtration assembly 4 filters passes through water one-way valve 5, one tunnel enters pressure water storage tank 8 and stores, another road passes to two water tap 7, exported according to customer need by two water tap 7, along with the water yield stored by pressure water storage tank 8 progressively increases, the pressure being loaded into pressure switch 6 also progressively raises, when pressure is increased to the trigger value of pressure switch 6, pressure switch 6 is triggered disconnection, now topping-up pump 2 is also controlled out of service, water-purifying machine is in holding state, when exporting water purification by two water tap 7, the pressure being loaded into pressure switch 6 can progressively reduce, when pressure is brought down below the trigger value of pressure switch 6, pressure switch 6 returns back to on-state, now topping-up pump 2 is controlled resumes operation,
The condensed water that reverse osmosis membrane filtration assembly 4 discharges is divided into two-way, leading up to backwater throttling valve 9, backwater check valve enters pre-filtering device 1 11 times, participate in once again after mixing with source water purifying, another road passes to two water tap 7, used as domestic water according to customer need output by two water tap 7, can also clean reverse osmosis membrane while use, the impurity concentration of pending water before can effectively reducing reverse osmosis membrane, can promote strainability and the work-ing life of reverse osmosis membrane;
The TDS value of pre-filtering device 1 water outlet can be detected by TDS detector 3, if the TDS value of pre-filtering device water outlet is higher than set(ting)value, then export corresponding signal by TDS detector and control the conducting of bypass magnetic valve 10, thus discharge a certain amount of waste water, after pre-filtering device stops the TDS value of waste discharge lower than set(ting)value, TDS detector exports corresponding signal control bypass magnetic valve 10 to be ended;
The present invention is on the basis of original Normal wastewater emission type water purification machine, can adjust the ratio that condensed water returns, waste water can be utilized to greatest extent, water-saving and environmental protection by backwater throttling valve 9.
Under desirable working order, namely when user can use the condensed water before film by two water tap, and when using more balanced during whole machine operation, this machine can reach the ideal effect that " zero " discharges;
For the extreme service condition that certain customers may occur, seldom may use bath water, the now special bypass magnetic valve 10 arranged, TDS proofing unit 3 detects the TDS value concentration of former water, by comparing the TDS value of preset value, control the break-make of bypass magnetic valve 10, under the prerequisite in work-ing life guaranteeing reverse osmosis membrane, the wastewater flow rate that condensed water discharge-channel is discharged is minimum, reaches the object of saving water resource.
