Embodiment 1

[0067] Example 1: Please refer to figure 1 . A mechanical double faucet is added to the waste water return system. The pure water outlet of the first reverse osmosis filter element 11a is divided into two lines, one of which is directly connected to the drinking water end of the double faucet. A high-voltage switch 16a, and the other is a pure water return pipeline R, which is used to return clean water to the front end of the first reverse osmosis filter element 11a; the waste water outlet of the first reverse osmosis filter element 11a is divided into two lines, and one line is directly connected to the life of the double faucet. The water ends are connected, and the fourth one-way valve 15d and the second high-pressure switch 16b are sequentially added to the pipeline; the other is the wastewater return pipeline, and the wastewater can return to the booster pump 12 through the first flow limiting valve 14a. There is a branch on the pipeline which is the first waste water d...

Embodiment 2

[0072] Example 2: Please refer to figure 2 . In this embodiment, on the basis of Embodiment 1, a pre-filter 17a is added at the front end of the booster pump 12. The type of the pre-filter 17a can be different forms of PP, different forms of activated carbon, ultrafiltration, nanofiltration and the above materials Composite filter elements, etc., the front outlet water flow rate is <8L / min.

[0073] The user opens the drinking water faucet (drinking water inlet 131 is connected to the outlet 133): the first high pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; After a reverse osmosis filter element 11a, it is divided into one path of pure water and one path of waste water. The pure water is discharged from the drinking water faucet for drinking, and the waste water flows back to the front of the pump through the first flow limiting valve 14a and mixes with the front outlet water to enter the first reverse osmosis filter ...

Embodiment 3

[0077] Example 3: Please refer to image 3 . In this embodiment, on the basis of Embodiment 1, a rear filter element 17b is added to the pure water outlet pipeline of the first reverse osmosis filter element 11a and before the pure water return pipeline. The type of the rear filter element 17b can be activated carbon in different forms.

[0078] The user opens the drinking water faucet (the drinking water inlet 131 is connected to the drain outlet 133): the first high pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; after tap water flows into the first reverse osmosis filter element 11a, the One path of pure water and one path of waste water, the pure water passes through the post filter element 17b and is discharged from the drinking water faucet for drinking, the waste water flows back to the pump through the first flow limiting valve 14a, mixes with the tap water and enters the first reverse osmosis filter element 11a a...

Abstract

According to the water path system, wastewater generated in the water purification process of a reverse osmosis filter element flows back to the front of the reverse osmosis filter element through a pipeline, and the wastewater is mixed with tap water and then enters the reverse osmosis filter element again for secondary filtration. According to the method, the discharge of wastewater can be greatly reduced while the performance and the service life of the reverse osmosis filter element are ensured; meanwhile, wastewater is connected with a domestic faucet, wastewater discharge is completed and wastewater is reutilized when the tap faucet is opened, and the requirement for ecological environmental protection is met; in addition, a waste water direct discharge pipeline is also arranged and is used for direct discharge of waste water when necessary; meanwhile, the system is provided with a pure water backflow branch, purified water flows back to the front end of the reverse osmosis filter element, raw water in front of the reverse osmosis filter element is washed and neutralized, no old water is left, a first cup of water can be drunk, the water quality is stable, and pure and fresh water is provided all the time.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a waterway system and a water purifier provided with the waterway system. Background technique [0002] Through the process of reverse osmosis, it is possible to move water from a more concentrated solution to a less concentrated one. Since inorganic ions, colloidal substances and macromolecular solutes cannot pass through the reverse osmosis reverse osmosis filter element, in this process, unnecessary substances are left at the end of the solution with high concentration, and purified pure water is obtained at the end with low concentration. The working process of the reverse osmosis filter element, the core component of the water purifier, is actually a process of liquid concentration. The salt content in the water increases continuously as the water flows through the surface of the reverse osmosis filter element, and the osmotic pressure of the water also increases con...
