Abstract
The invention discloses a scouring electromagnetic valve control method and a control system. In the control method and the control system, a water pump is enabled to work in a delaying time after a water purifier finishes producing water, and the scouring electromagnetic valve is turned on to continue scouring a membrane element so as to drain waste water concentrated during producing water previously out of the membrane element and further guarantee that water in the membrane element have no crystal scaling during the shut down period of the water purifier, thus the service life of the membrane element is prolonged.
Description
Technical field
The invention belongs to family expenses purifier technical field, relate to anti-penetration water purifier, relate in particular to the scouring electromagnetic valve control method and the control system of anti-penetration water purifier.
Background technology
Common anti-penetration water purifier or other water treatment product all possess the membrane component washing capacity, when water purifier starts, open scouring electromagnetic valve, with the water inlet of big flow the membrane component surface are washed; But there is drawback in such flushing; With the reverse osmosis membrane is example, because reverse osmosis membrane has inspissation to water inlet, the concentration of various impurity is all high than water inlet the waste water that therefore in reverse-osmosis membrane element, flows out; Under some situation, the concentration of impurity possibly reach the twice of water into even higher in the waste water.
During reverse-osmosis membrane element work, water inlet is constantly concentrated then discharges, and is surpassed its solubility but some indissoluble material concentrates back concentration; Form crystal, be deposited on the membrane component surface then, if can not in time these crystalline materials be discharged; These crystal will form the crystal fouling on the membrane component surface, and attached on the diaphragm, and the diaphragm that is adhered to by the deposition fouling has just reduced strainability; Directly cause membrane component effective film area to reduce, aquifer yield descends, and shorten service life.Generally, after water purifier system water finished, water pump quit work, and can not in time be discharged membrane component by the waste water that concentrates, and the crystalline solid of formation directly deposits to the film surface, causes the membrane component scaling fouling.
Summary of the invention
The object of the invention aims to provide a kind of scouring electromagnetic valve control method, can the waste water that concentrate in time be discharged membrane component through this control method, avoids crystalline solid to be deposited on the film surface and causes membrane component to pollute, to overcome the defective that prior art exists.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of scouring electromagnetic valve control method; Its process is: when the water conservancy project of water purifier system was done to finish, water pump also continued delay working, and in water pump delay working process; Open scouring electromagnetic valve membrane component is washed, discharged membrane component by the waste water that concentrates until will before making water.
Possibly produce maloperation for fear of the pure water pressure oscillation, said scouring electromagnetic valve just started after water pump delay working a period of time.
In addition, another object of the present invention is intended to also provide a kind of scouring electromagnetic valve to control system, and this control system comprises:
Control circuit board has delayer, driver and switching device on it;
High-voltage switch gear, water pump, scouring electromagnetic valve;
Said control circuit board is electrically connected with high-voltage switch gear, water pump, power supply, scouring electromagnetic valve;
Trigger when said delayer breaks off at high-voltage switch gear; Water pump works on; And by the driver drives switching device scouring electromagnetic valve is opened membrane component is washed; The waste water that will be concentrated until will before making water is discharged membrane component, and delayer finishes time-delay, and closes switching device by driver and make water pump stop to stop flushing with scouring electromagnetic valve.
Said switching device is two switching tubes, and a switching tube is used to open scouring electromagnetic valve, and another switching tube is used to switch off the pump and scouring electromagnetic valve.
More than be exactly scouring electromagnetic valve control method of the present invention and control system, compare prior art and have following advantage:
1. prevent reverse osmosis membrane fouling, prolong the service life of film;
2. prevent firm start, system's pure water TDS (total dissolved solidss) is higher.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated:
Fig. 1 is a scouring electromagnetic valve control system schematic of the present invention.
Among the figure:
100, control circuit board 1, switching tube 2, switching tube 3, delayer
4, driver 5, high-voltage switch gear 6, water pump 7, power supply
8, scouring electromagnetic valve
The specific embodiment
As shown in Figure 1, this is that scouring electromagnetic valve of the present invention is controlled system, comprises control circuit board 100, high-voltage switch gear 5, water pump 6, power supply 7, scouring electromagnetic valve 8.Include switching tube 1,2 on the control circuit board 100, delayer 3, driver 4.Wherein, control circuit board 100 is electrically connected with high-voltage switch gear 5, water pump 6, power supply 7, scouring electromagnetic valve 8.
The major function of high-voltage switch gear 5 is to gather pure water pressure, when not reaching setting pressure, and high-voltage switch gear 5 closures, delayer 3 is in holding state, water purifier system water, water pump 6 normally works on.When the pure water lateral pressure was increased to setting value, high-voltage switch gear 5 broke off, and delayer 3 is started working, and water pump 6 works on, the water manufacturing system operate as normal.The time-delay of delayer 3 is divided into two sections, and first section time-delay is in order to prevent that the pure water pressure oscillation from producing misoperation, when first section time-delay finishes, and second section time-delay beginning, driver 4 driving switch pipes 1 control scouring electromagnetic valve 8 is opened simultaneously, realizes flushing.When second section time-delay reached the time of setting, when promptly time-delay finished, driver 4 can send another signal and come gauge tap pipe 2, cuts off the electricity supply 7, and water pump 6 is shut down, and entering water electromagnetic valve is closed, and flushing finishes.So just accomplished the function of flushing before shutting down.
Through the time-delay flushing membrane element before shutting down, just will before make water and the concentrated waste water discharge membrane component of quilt, guarantee that the crystal fouling can not appear in the inner water of membrane component between down period, thus the service life of prolongation membrane component.
Through above-mentioned detailed description; Can find out that scouring electromagnetic valve control method of the present invention and system have the advantage of before waste water that concentrates in time being discharged membrane component in the water purifier shutdown; Avoid finishing crystal deposition and cause membrane component to pollute on the film surface, prolonged the service life of membrane component.
The above-mentioned specific embodiment is exemplary, is to be the restriction to this patent protection domain in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
