(1) water purification pattern
When water cleaning systems is opened water purification pattern, tap water is through the cotton filter core 2 of PP of pretreatment unit DY1, after the pre-treatment of particle charcoal filter core 4 and carbon rod filter core 5, enter reverse-osmosis treated cells D Y2, the water that temperature sensing device 18 and water monitoring device mix the dense water (elaborating below) of the water of being supplied by pretreatment unit DY1 separately or the water of being supplied by pretreatment unit DY1 and backflow carries out the monitoring of water temperature and TDS and monitoring numerical value is transferred to central processing unit, TDS monitor value can be calculated separately according to TDS monitoring numerical value by central processing unit or draw according to water temperature detection numerical value and TDS monitoring numerical value COMPREHENSIVE CALCULATING, central processing unit is controlled the pressure of supply water of potential device according to TDS monitor value, specifically, in the situation that TDS value does not surpass a preset value, the dense water that reverse osmosis treatment device 9 produces is back to the feed-water end of reverse osmosis treatment device at least in part by reverse checkvalve 17 and waste water ratio 16, that is to say, dense water can all reflux, or a part for dense water refluxes and another part is discharged from concentrated water drainage outlet.In the situation that TDS value surpasses a preset value, central processing unit control waste water ratio 16 is closed, Wastewater by Electric magnet valve 11 is opened, and the dense water that reverse osmosis treatment device 9 produces is all discharged from concentrated water drainage exit by Wastewater by Electric magnet valve 11.Under water purification pattern, when TDS monitor value increases, central processing unit is controlled potential device according to monitor value pressure of supply water is regulated and increased, and the maximum value that central processing unit control potential device regulates pressure of supply water to reach is V
maxwhen TDS monitor value reduces, central processing unit is controlled potential device 8 pressure of supply water is regulated and reduced, therefore, water cleaning systems can regulate automatically according to the variation of TDS monitor value the hydraulic pressure size of reverse osmosis treatment device influent side, thereby can farthest put forward the high yield water rate of recovery, reach water-saving result.
(2) reverse osmosis treatment device rinse mode
When water cleaning systems is opened reverse osmosis treatment device rinse mode, central processing unit is adjusted to a high-voltage value V by the pressure of supply water of potential device 8
cX, this high-voltage value V
cXcan be a fixing preset value, can be also that central processing unit is controlled the dynamic value of potential device 8 pressure of supply waters according to TDS monitor value, and, V
cX>V
max, therefore utilize V
cXhydraulic pressure value rinse reverse osmosis membrane processing device 9, can carry out cleaning down to the pollutent on RO film surface, developing result is good, RO film be difficult for to stop up.
As an embodiment more specifically, in conjunction with Fig. 1 and following table one, at water cleaning systems, during in water purification pattern, TDS preset value is made as 400, one TDS fragmentation value N
1be made as 200, when TDS value≤400 that TDS probe monitors, central processing unit is controlled waste water ratio 16 and is opened, Wastewater by Electric magnet valve 11 is closed, the dense water that RO membrane cartridge produces is back to thermo-bulb and TDS probe upstream side by reverse checkvalve 17 and waste water ratio 16 at least in part, and there are following two kinds of situations, one: 0 < TDS monitor value≤200 of situation, central processing unit is controlled transformation water pump according to TDS monitor value pressure of supply water is adjusted to 0.41Mpa; Two: 200 < TDS monitor value≤400 of situation, central processing unit is controlled transformation water pump according to TDS monitor value pressure of supply water is adjusted to V
max: 0.48Mpa.
When the TDS value monitoring when water monitoring device 19 is greater than 400, central processing unit controls waste water ratio 16 and cuts out, Wastewater by Electric magnet valve 11 is opened, the dense water that RO membrane cartridge produces is all discharged from concentrated water drainage exit by Wastewater by Electric magnet valve 11, and there are following two kinds of situations, one: 400 < TDS monitor value≤600 of situation, central processing unit is controlled transformation water pump according to TDS monitor value pressure of supply water is adjusted to 0.55Mpa; Two: 600 < TDS monitor value≤1000 of situation, central processing unit is controlled transformation water pump according to TDS monitor value pressure of supply water is adjusted to 0.62Mpa.
Therefore, by the above and table one, can be found out, according to the TDS preset value setting: 400, central processing unit is controlled water cleaning systems by judgement TDS monitor value numerical range of living in, and to realize dense water, reuse or dense water are all drained at least in part, not only can put forward the high yield water rate of recovery, also can reduce R0 film pollutes, and, under reverse osmosis treatment device flushing state, pressure of supply water compared to transformation water pump in 0 < TDS value≤200 and 200 < TDS value≤400 situations is respectively 0.41Mpa and 0.48Mpa, central processing unit can further be controlled transformation water pump hydraulic pressure is heightened to the 0.62Mpa that higher 0.55Mpa is even higher, so, can to the pollutent on the R0 film surface of RO membrane cartridge, rinse better, reducing R0 film pollutes.
When water cleaning systems is opened reverse osmosis treatment device rinse mode, central processing unit is adjusted to a high-voltage value V by the pressure of supply water of transformation water pump
cX: 0.55Mpa, V
cX>V
max, so the pollutent on RO film surface is by cleaning down, RO film is difficult for stopping up.
Table one: the correlation parameter under two kinds of different working modes
The above embodiment has only expressed preferred forms of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
