Description
Technical Field
The utility model relates to the technical field of water purifiers, in particular to a waterway system with a wastewater direct discharge pipeline.
Background
By the reverse osmosis process, water can be passed from a high concentration solution to a low concentration solution. Since inorganic ions, colloidal substances and macromolecular solutes cannot pass through the reverse osmosis filter cartridge, unwanted substances remain at the end of the solution having a high concentration during this process, while purified pure water is obtained at the end having a low concentration. The process of the core part reverse osmosis filter element of the waterway system is actually a liquid concentration process, and the salt content in water is continuously increased along with the increase of the water flowing through the surface of the reverse osmosis filter element, and the osmotic pressure of the water is also continuously increased. When the osmotic pressure increases to the pressure of the booster pump, water cannot flow into the clean water side through the reverse osmosis cartridge. The part of the water which fails to pass is the waste water generated in the process of making water.
The lower the amount of wastewater, the higher the recovery rate (water yield/total water intake 100%), the more easily colloids, organic pollutants and scale-forming ions are deposited on the surface of the reverse osmosis filter element, which causes the blockage of the reverse osmosis filter element, and the reduction of the water yield and the desalination rate.

When the domestic water tap is opened, the waste water generated and accumulated in the water making process can be discharged through the domestic water tap for domestic water use, and the waste water utilization is really realized.
Wastewater straight-line procedure 1: when the user gets the drinking water, because the waste water backward flow, the play water TDS can increase along with the increase of water intaking time, consequently, design when the user gets after the drinking water time reaches a definite value (first preset duration preferred 1-5min), start the straight row procedure of waste water (time preferred 5-300s), it is the waste water of discharging while getting water this moment, booster pump 12 keeps starting, keep normal system water state promptly, first ooff valve 18a and second ooff valve 18b open, the waste water that two reverse osmosis filter cores produced is discharged along with the straight row pipeline of waste water, the initial level can be resumeed in the play water TDS short time, and it is less to drinking water flux influence.
Wastewater straight-line procedure 2: when the situation that the user does not use the water purifier (the intelligent water outlet assembly 13 is not started) for a long time (the second preset time is preferably 10min-10h) is monitored, starting the wastewater direct discharging program 2 (the time is preferably 5-300s), and only discharging wastewater at the moment; the booster pump 12 is not started, the first flow limiting valve 14a, the second flow limiting valve 14b, the first switch valve 18a and the second switch valve 18b are all opened, tap water flows out from the wastewater side after entering the two reverse osmosis filter elements by means of the pressure of tap water and is directly discharged into the two wastewater straight discharge pipelines, the replacement of water in the two reverse osmosis filter elements and the wastewater pipelines is completed, the scaling of the two reverse osmosis filter elements, the two flow limiting valves and the two switch valves is prevented, and the service lives of the two reverse osmosis filter elements, the two flow limiting valves and the two switch valves are prolonged. Under the normal condition, the user opens life tap and can accomplish the washing to two reverse osmosis filter cores and waste water return line, and this procedure mainly used avoids having no use life water needs again after the user has got the drinking water, makes backward flow waste water be detained in two reverse osmosis filter cores and return line for a long time, causes the incrustation scale deposit and influences life's problem.
In order to facilitate the control of the inflow water, on the basis of the above embodiment, an inflow valve may be disposed between the upstream of the pre-filter 17a or the intersection of the flow path where the pump inlet 121 is located and the first branch P1 and the pre-filter 17a, and the inflow valve is a valve body with a full-open or full-close function.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
