The control method of the reverse osmosis system provided by the embodiment of the application comprises the following steps:
s1, detecting the temperature T of water entering a pre-filter element or a reverse osmosis filter element;
s2, when T is greater than a first preset temperature, the first waste water electromagnetic valve is controlled to work and the second waste water electromagnetic valve is controlled to stop working, when T is less than the first preset temperature and greater than a second preset temperature, the second waste water electromagnetic valve is controlled to work and the first waste water electromagnetic valve is controlled to stop working, and when T is less than the second preset temperature, the first waste water electromagnetic valve and the second waste water electromagnetic valve are controlled to work simultaneously.
Specifically, when the reverse osmosis system 10 works, water flow firstly sequentially passes through the pre-filter element 11 and the temperature sensor 12 to enter the reverse osmosis filter element 14, in the process, the temperature sensor 12 can sense the water flow temperature and feed back a detected water flow temperature signal to the controller, the controller judges a received water temperature signal and then controls the on-off of the first wastewater electromagnetic valve 16 and the second wastewater electromagnetic valve 17, so that the water production efficiency of the reverse osmosis system 10 is ensured, and the water use requirement of a user is met.
When the reverse osmosis system 10 is in operation, the controller compares the received water temperature T with the first preset temperature and the second preset temperature, when the water temperature T is greater than the first preset temperature, the controller controls the second waste water electromagnetic valve 17 to open and the first waste water electromagnetic valve 16 to operate, i.e. the valve port of the second waste water electromagnetic valve 17 is completely opened and does not generate damping action on water flow, the first waste water electromagnetic valve 16 generates damping action on water flow to pressurize the water flow in the reverse osmosis filter element 14, the working pressure in front of the membrane of the reverse osmosis filter element 14 is not required to be too high, still has larger flux, can meet the requirement of the user on the water flow, and moreover, when the water temperature T is greater than the first preset temperature, the working pressure in front of the membrane of the reverse osmosis filter element 14 is lower, the damage on the reverse osmosis filter element 14 can be reduced, and the service life of the reverse osmosis filter element 14 can be prolonged.
When T is smaller than the first preset temperature and larger than the second preset temperature, the working efficiency of the reverse osmosis filter element 14 is reduced because the temperature is lower at the moment, the controller controls the first waste water electromagnetic valve 16 to be opened, the second waste water electromagnetic valve 17 to work, namely, the valve port of the first waste water electromagnetic valve 16 is completely opened, no damping effect is generated on water flow, the second waste water electromagnetic valve 17 generates damping effect on water flow to pressurize the water flow in the reverse osmosis filter element 14, and the working pressure in front of the membrane of the reverse osmosis filter element 14 is improved by using the electromagnetic valve with smaller flux, so that the purposes of improving the water flow speed of the reverse osmosis system 10 and increasing flux are achieved.
When the temperature T is smaller than the second preset temperature, the water flow temperature is too low, the filtering efficiency of the reverse osmosis filter element 14 is severely restricted, the controller controls the first wastewater electromagnetic valve 16 and the second wastewater electromagnetic valve 17 to work simultaneously, the first wastewater electromagnetic valve 16 and the second wastewater electromagnetic valve 17 generate damping action on water flow simultaneously to pressurize the water flow in the reverse osmosis filter element 14, the pressure in front of the membrane of the reverse osmosis filter element 14 is guaranteed to be maximum, the water flow speed and the pure water flux of the reverse osmosis system 10 are improved to the greatest extent, and the normal water demand of a user in a low-temperature environment is guaranteed.
For example, in the present embodiment, the first predetermined temperature is 25 ℃, and the second predetermined temperature is 15 ℃. When the reverse osmosis system works, water flow firstly sequentially passes through the pre-filter element 11 and the temperature sensor 12 to enter the reverse osmosis filter element 14, and in the process, the temperature sensor 12 senses the water flow temperature and feeds back signals to the controller according to the water flow temperature.
Specifically, when the water flow temperature is higher than 25 ℃, the controller controls the second waste water electromagnetic valve 17 to be opened, the first waste water electromagnetic valve 16 is kept to work continuously, namely, the valve port of the second waste water electromagnetic valve 17 is completely opened, no damping effect is generated on water flow, the first waste water electromagnetic valve 16 generates damping effect on water flow to pressurize the water flow in the reverse osmosis filter element 14, the working pressure in front of the membrane of the reverse osmosis filter element 14 is not required to be too high, the system still has larger flux, and the requirement of a user on water quantity can be met.
When the water flow temperature is lower than 25 ℃ and higher than 15 ℃, the first waste water electromagnetic valve 16 is opened, and the second waste water electromagnetic valve 17 is kept to work, namely, the valve port of the first waste water electromagnetic valve 16 is completely opened, no damping effect is generated on the water flow, and the second waste water electromagnetic valve 17 generates damping effect on the water flow so as to pressurize the water flow in the reverse osmosis filter element 14. Because when the temperature is less than 25 ℃, the working efficiency of the reverse osmosis filter element 14 is reduced, the working pressure before the membrane of the reverse osmosis filter element 14 is improved by using the electromagnetic valve with smaller flux, and because the temperature is greater than 15 ℃, the working pressure before the membrane of the reverse osmosis filter element 15 can be adjusted by only keeping the working of the second wastewater electromagnetic valve 17, thereby achieving the purposes of improving the water flow speed of the reverse osmosis system 10 and increasing the flux.
When the water flow temperature is less than 15 ℃, the controller controls the first waste water electromagnetic valve 16 and the second waste water electromagnetic valve 17 to work simultaneously, namely the first waste water electromagnetic valve 16 and the second waste water electromagnetic valve 17 generate damping action on the water flow simultaneously so as to pressurize the water flow in the reverse osmosis filter element 14. Because the filtration efficiency of the reverse osmosis filter element 14 will become lower when the water temperature is lower than 15 ℃, the first wastewater electromagnetic valve 16 and the second wastewater electromagnetic valve 17 simultaneously generate damping action on the water flow to pressurize the water flow in the reverse osmosis filter element 14, so that the reverse osmosis filter element 15 is ensured to have higher working pressure before the membrane, and further the water flow speed and flux of the reverse osmosis system 10 are ensured not to influence the normal requirement of the user.
