example 1

[0057] For example one, see figure 2 As shown, the flow-restricting channel assembly 3 includes a first guide channel, and the vertical section at the junction of the first guide channel and the side wall of the concentrated water tank 1 is a vertical bar shape (see figure 2 shown) or a vertical "Y" shape (see image 3 shown).

example 2

[0058] Example 2, see Figure 4 As shown, the flow-restricting channel assembly 3 includes a plurality of second flow-guiding channels. The vertical section of the connection between the plurality of second diversion channels and the side wall of the concentrated water tank 1 is arranged in layers in a string of beads from bottom to top. And the low point of the connection between each second diversion channel and the inner wall of the concentrated water tank 1 is higher than or equal to the low point of the connection between the second diversion channel and the inner wall of the raw water tank 2 . Further, the vertical section of the connection between the second diversion channel and the side wall of the concentrated water tank 1 is circular or elliptical.

[0059] In order to ensure that the concentrated water tank 1 can store more concentrated water, the connection between the flow limiting channel assembly 3 and the side wall of the concentrated water tank 1 is arranged...

specific Embodiment 1

[0153] It is determined that the stratified drainage threshold corresponding to each preset measurement position 111 gradually decreases from bottom to top.

[0154] The stratified drainage threshold includes a first stratified drainage threshold. The first stratified drainage threshold includes values ​​greater than the upper limit.

[0155] For example, continuing the above example, the upper limit value is 570ppm, and the first stratified drainage threshold value is greater than 570ppm.

[0156] Determining that the layered drainage threshold corresponding to the preset measurement position 111 of each layer gradually decreases from bottom to top, including the following steps:

[0157] S703a-1. Determine that the bottom-up first layer preset measurement position 111 corresponds to the first layer drainage threshold.

[0158] For example, continuing the above example, the first layer preset measurement position 111 corresponds to the first layer drainage threshold value: ...

Abstract

The invention provides a device and method for adjusting the quality of purified water and a water purification system. According to the device for adjusting the quality of the purified water, purified water can be collected for drinking, concentrated water can be recycled, and a complete closed water purification treatment process of the water purification system is realized. The energy consumption is reduced, the discharge ratio of the concentrated water is enlarged, the concentrated water concentration polarization at the concentrated water side of a semi-permeable membrane (permeable membrane) is avoided, and the service life of the semi-permeable membrane (permeable membrane) is ensured. active control over the concentrated water input into a raw water tank is achieved through cooperation of a flow limiting channel assembly of a concentrated water tank and a concentrated water discharging switch, and passive control over initial liquid supplementation performed after the raw water tank is lack of water is achieved through a floating ball valve, namely a linkage relation in which one of the flow limiting channel assembly and the floating ball valveactively supplements liquid and the other one passively supplements liquidenables the water quality to be maintained in a set value interval for a long time, and metal ions which are easy to absorb by a human body are reserved, so that drinking water is safe and healthy. Meanwhile, the device for adjusting the quality of the purified water is effectively sterilized, and bacterial regeneration is inhibited.

Description

technical field [0001] The present disclosure relates to the field of water purification, in particular to a device and method for adjusting water quality of purified water and a water purification system. Background technique [0002] In order to achieve the purpose of water saving, the existing water purifiers recycle clean water much more than discharge concentrated water, increase the concentration polarization, accelerate the decay of the life of the semi-permeable membrane (or permeable membrane), and lead to abnormal discharge. [0003] At the same time, there are differences in water quality and water temperature in various regions, and the intervention effect through the concentrated water discharge regulating valve is not ideal. If the water hardness is high, the application effect cannot be achieved with low discharge. Similarly, as the water source changes with the environment, the quality of the purified water produced by the water purifier also changes, such a...
