Water purification system with constant pure water/wastewater proportion and water purifier

Abstract

The invention discloses a water purification system with a constant pure water / wastewater proportion and a water purifier. The water purifier is used for desalting and water purifying through the water purification system with a constant pure water / wastewater proportion; the water purification system is provided with an EDR unit, a concentrated water plug for controlling the flow rate of concentrated water, a flow regulating valve for regulating the flow rate of pure water and a booster pump for increasing the flow rate of raw water; the booster pump is assembled at the communication part of the raw water pipeline and the water inlet of the EDR unit; the first water outlet of the EDR unit is connected with a concentrated water pipeline, the concentrated water plug is assembled at the pipeline of the concentrated water pipeline, the second water outlet of the EDR unit is communicated with the water inlet end of the flow regulating valve through a pipeline, the water outlet end of the flow regulating valve is communicated with a pure water pipeline, and the water inlet of the EDR unit is communicated with the raw water pipeline. A certain pressure is applied to raw water through thebooster pump arranged in front of the EDR unit, and the flow of produced water of the EDR unit is regulated and controlled in combination with a flow regulating valve at a water outlet of the EDR unit, so that the pure water / wastewater proportion of the produced water of the water purification system is constant, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a water purification system and a water purifier with a constant ratio of pure waste water. Background technique [0002] Most reverse osmosis water purifiers use reverse osmosis filter elements for water purification operations, and the reverse osmosis filter elements have reverse osmosis membranes. When the raw water enters the reverse osmosis water purifier, a certain pressure is applied to the water to make the water molecules and ionic mineral elements in the raw water pass through the reverse osmosis membrane, while the macromolecular inorganic salts in the tap water include heavy metal ions, organic matter, bacteria and Viruses cannot pass through the reverse osmosis membrane with small membrane pores to achieve water purification. [0003] The reverse osmosis membrane technology in the prior art cannot readjust the water quality of the produced water, that is, th...

Problems solved by technology

[0003] The reverse osmosis membrane technology in the prior art cannot readjust the water quality of the produced water, that is, the concentrated water cannot be filtered and utilized again, resulting in waste of water resources, and when the pure water in the produced water of the system is mixed with When the ratio of concentrated water exceeds 3:1, the risk of reverse osmosis membrane operation will increase, the purification rate will decrease, and the water quality of the produced water will also deteriorate accordingly. Correspondingly, the proportion of pure waste in the produced water of the water purification system will not be high. Stable, unable to guarantee the quality of produced water, affecting user experience
