A kind of anti-penetration water purifier with return of waste water system further includes return line 18, the both ends of the return line 18
The waste water end of RO membrane filter 8 and the water inlet end of the first inlet water solenoid valve 6 are separately connected, along the stream of waste water on the return line 18
To waste water solenoid valve 9 and third inlet water solenoid valve 11 is successively arranged, the water outlet of the waste water solenoid valve 9 is also connected with waste pipe
Road 19, the waste line 19 are equipped with the second inlet water solenoid valve 10.
Anti-penetration water purifier further includes master control set, and the master control set is intake with the first TDS probe 3, first electric respectively
Magnet valve 6, booster pump 7, waste water solenoid valve 9, the second inlet water solenoid valve 10, third inlet water solenoid valve 11, the 2nd TDS probe 12 and height
Compress switch 14, the master control set is single-chip microcontroller or PLC.
A kind of workflow and control method of the anti-penetration water purifier with return of waste water system:
1, when tap 16 is opened, high-voltage switch gear 14 detects that the pressure in water pipeline 17 declines and transmits signal
To master control set, master control set starts water program processed: the first inlet water solenoid valve 6 is opened, and is started to work with after booster pump 7, originally
Water enters water pipeline 17 by triple valve 1, reaches at the first TDS probe 3 after the decompression of pressure reducing valve 2, the first TDS probe 3 is immediately
Tap water quality is detected, and will test result and feed back to master control set.
2, as the first 3 detected values of TDS probe≤A, (A is master control set setting value, and≤A is normal water matter, and > A is exceeded
Water quality), the second inlet water solenoid valve 10 use close n1 seconds, the mode opened n2 seconds work alternatively (n1, n2 for master control set setting value,
Wherein A value, n1, n2 are determined by experimental data and are solidificated in master control set)；Waste water solenoid valve 9 works normally, and tap water is successively
It is filtered by PP cotton filter element 4, the first active carbon+PP cotton composite filter element 5, and under the action of booster pump 7 by RO membrane filter 8,
RO membrane filter 8 generate waste water flow through Wastewater by Electric magnet valve 9 after, the second inlet water solenoid valve 10 close the n1 second during, third into
Water solenoid valve 11 is in the open state, and waste water starts reflux (before the pressure of the water after the pressurization of booster pump 7 is higher than booster pump 7
Hold the pressure of not pressurized water, therefore return line 18 can normal reflow), in n2 phase second that the second inlet water solenoid valve 10 is opened
Between, third inlet water solenoid valve 11 is in close state (guarantee the 8 front end not pressure release of RO membrane filter), waste water be exhausted directly to water purifier with
Outside, the range in 8 service life of RO membrane filter is influenced to guarantee that the TDS value of 8 front end of RO membrane filter persistently rises to not due to system flowback.
I.e. waste water solenoid valve 9 is normally opened, and the second inlet water solenoid valve 10 and third inlet water solenoid valve 11 are alternately opened.
3, as 3 detected value > A of the first TDS probe, waste water solenoid valve 9 is worked normally, and the second inlet water solenoid valve 10 is opened,
Third inlet water solenoid valve 11 is closed, and waste water is without reflux, to prevent high TDS value tap water return of waste water damage RO membrane filter 8.
4, when water purifier rinses, 9 standard-sized sheet of waste water solenoid valve, the second inlet water solenoid valve 10 is opened, third inlet water solenoid valve
11 close, and flushing waste water is directly discharged to outside water purifier.
5, by the filtered pure water of RO membrane filter 8, after improving mouthfeel using the second active carbon+PP cotton composite filter element 15
Becoming direct drinking facilitates user to drink.The filtered pure water rear end of RO membrane filter 8 be equipped with the 2nd TDS probe 12 detect it is pure
Water water quality simultaneously will test value and feed back to master control set to show on a display screen, and user is facilitated to perceive pure water water quality.
6, when tap 16 is closed, water purifier maintenance work, at this time on 8 pure water rear end water route of RO membrane filter
Under the action of non-return valve 13,13 rear end hydraulic pressure of non-return valve persistently rises, and when hydraulic pressure rises to 14 threshold values of high-voltage switch gear, height is pressed off
14 take-offs are closed, and transmit signals to master control set, master control set controls the first inlet water solenoid valve 6, booster pump 7, waste water electromagnetism
Valve 9, the second inlet water solenoid valve 10, third inlet water solenoid valve 11 are closed, and are cut off water route and are stopped water processed.
7, in this patent formula, include not only this scheme of the first 3 detected values of TDS probe≤A, further include A1 < first
Return of waste water scheme in some interval range such as 3 detected values of TDS probe≤A2.
It is described above be only the utility model Application Example, certainly cannot with this come limit the utility model it
Interest field, therefore equivalence changes made according to the patent scope of the utility model, still belong to the protection scope of the utility model.
