The embodiment of the invention comprises the following steps:
a water treatment primary reverse osmosis automatic operation method comprises the following steps:
step 1: the equipment is used for feeding water, tap water enters a raw water tank through the control of a water feeding electromagnetic valve, a raw water tank full water floating ball and a raw water tank water shortage floating ball are arranged in the raw water tank, and the raw water tank full water floating ball is linked with the water feeding electromagnetic valve; when the original water tank full water floating ball has no signal, the water-feeding electromagnetic valve is opened to feed water, and when the original water tank full water floating ball has a signal, the water-feeding electromagnetic valve is automatically closed;
the touch screen displays and monitors the water level of the original water tank in real time, controls the tap water to enter and reverse osmosis water supply, and solves the problems of water level overflow and idle running of a water-deficient motor of equipment during the process of managing the equipment without people.
Step 2: the pretreatment is started, whether the raw water tank is lack of water is determined through a signal of a water lack floating ball of the raw water tank, when water exists, the raw water pump pumps the water from the raw water tank to a quartz sand filter and an active carbon filter, and when the water is lack, the raw water pump is not started; the raw water pump is provided with a raw water high-voltage protection switch and a raw water pump thermal protection module; the raw water high-pressure protection switch monitors the water outlet pressure of the raw water pump, and the raw water pump stops when the water outlet pressure of the raw water pump is too high; the raw water pump thermal protection module monitors the temperature of the raw water pump during operation, and the raw water pump stops when the temperature is too high;
the touch screen displays and monitors the pressure of the pretreatment pipeline in real time, and avoids that the pipeline and the filter are broken due to overhigh pressure caused by that the pretreatment filter is blocked and the raw water pump continuously supplies water. The system controls the raw water pump to start and stop through the raw water high-voltage protection switch, and the situations are effectively avoided. The main focus is on the setting of the pressure switch parameters.
And step 3: reverse osmosis host start-up
Because the inlet water of the reverse osmosis membrane needs to be under certain pressure to reach the water yield of the membrane. The salt content of the permeable membrane is diluted by the rated water yield, the salt permeability is reduced, and the salt rejection rate is improved. When the water inlet pressure exceeds a certain value, the concentration polarization is increased due to the overhigh recovery rate, the salt permeability is increased, the increased water yield is offset, and the desalination rate is not increased any more. Too high pressure can lead to the rivers speed too fast again, and the quick striking of impurity in the aquatic is on reverse osmosis membrane piece, and long-term operation leads to the direct perforation of membrane to scrap. Therefore, the water pressure needs to be increased to a specified pressure by the booster motor, and a high-pressure protection switch needs to be added behind the pump to prevent the water pressure from being too high. Playing a role of protection.
Conveying the water filtered in the step (2) to a reverse osmosis membrane through the pressurization of a pressurization motor, filtering the water by the reverse osmosis membrane, allowing the generated pure water to enter a pure water tank, allowing the concentrated water to enter a concentrated water tank, and arranging a flushing electromagnetic valve between the reverse osmosis membrane and the concentrated water tank; before the water filtered in the step (2) enters the booster motor, the water outlet pressure is monitored through a low-voltage protection switch, the booster motor is not started when the water outlet pressure is insufficient, and the booster motor is started when the water outlet pressure is sufficient; the supercharging motor is provided with a high-voltage protection switch and a supercharging motor thermal protection module, the supercharging motor is stopped when the high-voltage protection switch monitors that the water outlet pressure of the supercharging motor is too high, and the supercharging motor is stopped when the supercharging motor thermal protection module monitors that the operation temperature of the supercharging motor is too high;
through the preceding pressure switch of reverse osmosis booster motor, the processing effluent pressure of real-time supervision, when water pressure did not reach the low limit value that pressure switch set up in the pipeline, reverse osmosis booster motor can not start. When the water yield of the prior treatment is insufficient, the booster motor of the reverse osmosis equipment at the back can forcibly pump the water of the prior treatment, so that the impurities filtered in the prior treatment equipment are easily pumped out, and the deformation of the filtering tank and the blockage of the reverse osmosis membrane are caused. Therefore, 2 high-pressure and low-pressure switches which are monitored in real time are added in the front and at the back of the booster motor, so that the situations of the above situations can be avoided, and the situations of the water quality reduction of reverse osmosis membrane water production caused by overhigh water pressure and the equipment damage caused by overhigh pressure can be prevented.
And 4, step 4: water storage tank and pure water delivery
The water produced by reverse osmosis is concentrated water and pure water, and the concentrated water can be directly discharged or used as cleaning water in daily life. Pure water is the main water produced by the equipment and directly enters the pure water tank. The pure water tank and the concentrated water tank are both provided with full water floating balls, when the liquid level reaches a certain height, the full water floating balls give out signals, the reverse osmosis equipment is stopped, and when the liquid level falls to a certain height, the reverse osmosis equipment is started again.
The delivery pump is controlled to be opened through the water-deficient floating ball of the pure water tank, and after pure water enters the delivery pump, because the use point is not in a normally open state, water does not flow in the pipeline after the use point valve is closed, pressure can be increased, and at this time, a pressure release valve needs to be added on the pipeline, or a valve and a backflow pipeline are added at the back of the use point, so that water circulates all the time.
The technical advantages are as follows: the pressure of the conveying pipeline is monitored in real time, and the phenomenon that the conveying pump continuously operates to cause overhigh pipeline pressure under the condition that a valve at a use point is closed can be avoided.
And 5: runtime settings
The time delay starting time of the booster motor is set to be the time delay starting time of the reverse osmosis booster pump compared with other electrical appliances when the equipment automatically operates, so that the condition that the water pressure of the pre-treated effluent is not enough when the equipment is just started is prevented.
The booster pump is started in a water-deficient delayed mode, and the problem that the booster pump is frequently started due to frequent jumping of the low-voltage protection switch under the condition that water pressure is unstable can be avoided.
And the flushing time of the flushing electromagnetic valve is set to be the flushing time for opening the electromagnetic valve to carry out direct flushing after the reverse osmosis equipment runs for a period of time when the reverse osmosis equipment automatically runs, and the direct flushing is used for quickly flushing away scales in the reverse osmosis membrane and preventing the membrane from being blocked.
