Wherein, this reverse osmosis membrane water-purifying machine also comprises a pressure water storage container.
Wherein, this wastewater outlet and this discharge mechanism provide the by-pass channel of domestic water through pipe connection formation one.
In the utility model, but above-mentioned optimum condition arbitrary combination on the basis that meets this area general knowledge promptly gets each preferred embodiment of the utility model.
The positive progressive effect of the utility model is: the reverse osmosis membrane water-purifying machine of the utility model is provided with the TDS proofing unit on the backwater channel that reclaims waste water; And the SV that setting is controlled by the TDS proofing unit on the discharge of wastewater passage; Thereby the TDS concentration to the waste water in reverse osmosis membrane downstream is monitored; When TDS concentration was lower than this set(ting)value, waste water can get into by-pass channel and be used as domestic water, perhaps converged again from the upper reaches and water source that backwater channel is sent filtration unit back to and filtered; When TDS concentration is higher than set(ting)value; Open by TDS proofing unit control SV; With waste water by the discharge of wastewater passage to outside drain, thereby play reverse osmosis membrane is cleaned, with a large amount of metathetical effects of the waste water of the high density before the reverse osmosis membrane filt; Reduce the impurity concentration of the preceding pretreated water of reverse osmosis membrane effectively, the work-ing life of guaranteeing reverse osmosis membrane.
Further; By-pass channel can cause discharging device as domestic water with waste water; When domestic water during normal the use, also " in passing " reduced the TDS concentration of the preceding source of film water, when domestic water is on the low side; Through the action of TDS proofing unit control SV, and the water of TDS excessive concentration then can be discharged from the discharge of wastewater passage.
Description of drawings
Fig. 1 is the internal structure synoptic diagram of the reverse osmosis membrane water-purifying machine in the utility model one preferred embodiment.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As shown in Figure 1, identical with prior art, the reverse osmosis membrane water-purifying machine of the utility model has comprised three grades of preposition filtration units 1, connects a topping-up pump 2 in its downstream, and the downstream of this topping-up pump 2 connect a reverse osmosis membrane filt 3.The upper reaches of these three grades of preposition filtration units 1 connect the water source.Three grades of preposition filtration units 1 in the utility model adopt the cotton strainer of Vestolen PP 7052, activated charcoal filter and extruded activated carbon rod strainer respectively.
And this reverse osmosis membrane filt 3 comprises a pure water inlet 5 and a wastewater outlet 4.This pure water inlet 5 forms water purification passage 8 with water tap 9 as discharge mechanism through pipe connection, on this water purification passage 8, also connects a pressure water storage container 10, is used to store the water purification that temporarily need not use.
Between the upper reaches of the downstream of this pure water inlet 5 and pressure water storage container 10, be provided with a vacuum breaker 6 and a high-voltage switch gear 7, be respectively applied for and prevent that water purification from refluxing and prevent to press in the pressure water storage container 10 too high (moisture storage capacity is full).This pressure water storage container 10 has guaranteed that water purification also can successfully be emitted from water tap 9 when insufficient pressure.This pressure water storage container is the commercially available prod, repeats no more at this.
In addition, this wastewater outlet 4 forms the by-pass channel 11 that domestic water is provided with this water tap 9 through pipe connection.
Difference from prior art is that the wastewater outlet 4 of this reverse osmosis membrane filt passes through to form a return flow line 15 behind the pipe connection with the upper reaches of three-stage filtration device 1.Can come back to the upstream side of three-stage filtration device 1 via this return flow line 15 by wastewater outlet 4 effusive waste water, send into reverse osmosis membrane filt 3 by topping-up pump 2 again after merging with the water source and carry out purifying treatment, purify once more.Water purification after the purification flows into water purification passage 8 in order to using from pure water inlet 5.
On this return flow line 15, also be provided with a TDS proofing unit 12 near these wastewater outlet 4 places, be used to detect the solids concn of wastewater outlet 4 effusive waste water.The downstream part that on return flow line 15, is positioned at TDS proofing unit 12 is provided with a vacuum breaker 16.
And in order the TDS value have been surpassed this water-purifying machine of waste water discharge of preset value; The upstream side that on this return flow line 15, is positioned at this vacuum breaker 16 is drawn a discharge of wastewater passage 17; And through SV 14 its break-makes of control by above-mentioned TDS proofing unit 12 controls, the outlet of this discharge of wastewater passage 17 is in communication with the outside.When the TDS value that detects wastewater outlet 4 surpasses preset standard, TDS proofing unit 12 control SVs 14 are opened, thus directly discharging and no longer flow to the purification that preposition filtration unit 1 carries out once more of waste water, thus improved the work-ing life of reverse osmosis membrane.Through with the synergy of TDS proofing unit 12; This water-purifying machine is through the switch of preset TDS duty control solenoid valve 14; From the waste water of discharge of wastewater passage 17 minimize emissions amounts, under the prerequisite in the work-ing life of guaranteeing reverse osmosis membrane, reach the purpose of combustion with minimal waste water.Above-mentioned TDS proofing unit and be the commercially available prod by the vacuum breaker and the SV of its control repeats no more at this.
In addition,, make waste water to be utilized to greatest extent, also be provided with a flow-limiting valve 13 at the upper reaches of vacuum breaker 16 in order to do further planning to the ratio of returning of the waste water that reclaims.
Can be as the user through water tap 9 use part waste water, when whole water-purifying machine on period usage ratio was balanced, this water-purifying machine can be realized the purpose of waste water " zero " discharging, more reasonably utilizes the water source, reaches the effect of water-saving and environmental protection.
Though more than described the embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
