Set up leading filter core and carry out first heavy filtration to the raw water that gets into the EDR unit, reduce the macromolecular substance that gets into the EDR unit, reduce the scale deposit risk of EDR unit.
It should be noted that the pre-filter element at the raw water pipeline may also be disposed at the pipeline between the pressure sensor and the booster pump. The connection mode in the present embodiment is not limited.
When the system is in a normal water purification working condition, raw water sequentially flows through a booster pump, a preposed filter element and a pressure sensor and then enters an EDR unit, the booster pump applies force to the raw water, the water flow speed of the raw water is accelerated after the raw water passes through the booster pump, the preposed filter element filters the raw water for the first time, macromolecular substances are reduced to enter the EDR unit, the pressure sensor keeps the pressure of the raw water to the EDR unit stable, the EDR unit desalinates and purifies the raw water, concentrated water with higher concentration is discharged from a first water outlet and enters a concentrated water pipeline, pure water with lower concentration is discharged from a second water outlet and enters a pure water pipeline, the outflow of the concentrated water pipeline is adjusted through a concentrated water plug, a flow adjusting valve adjusts the flow of the pure water, when the drainage of the concentrated water is too large, the flow adjusting valve increases the flow of the pure water, when the drainage of the concentrated water is too small, thereby keeping the pure waste ratio of the produced water of the water purification system in a stable state, detecting the water discharge amount of the pure water through the flowmeter, and designing the TDS detector to detect the TDS value of the pure water.
When the water flow of the pure water needed by the user is large, the flow regulating valve is opened greatly, and meanwhile, the booster pump in front of the EDR unit also needs to correspondingly select the pressure mode with large pressure, so that the pressure applied by the raw water to the EDR unit is increased, the flow of the concentrated water is improved, and the constant pure waste proportion of the system is kept.
When the water flow required by a user is small, the flow regulating valve is closed, and meanwhile, the booster pump in front of the EDR unit also needs to correspondingly select a pressure mode with small pressure, so that the pressure applied by raw water to the EDR unit is reduced, the flow of concentrated water is reduced, and the constant pure waste proportion of the system is kept.
When the system is in different leaving water temperature, can be through predetermineeing different pressure values to the booster pump, make the booster pump be in under the pressure mode of difference, for example normal atmospheric temperature water, hot water or boiling water etc. the user is different to the demand of pure water under the different temperatures, consequently can select corresponding pressure value according to the difference of temperature to keep under the different temperatures, water purification system's steady operation keeps the pure waste water proportion of producing water stable.
