Problems solved by technology

[0005] 2. To make the service life of the reverse osmosis membrane longer, if only the above measures are taken, the service life of the reverse osmosis membrane is not ideal in many cases
However, this solution can only reduce the amount of wastewater discharged when the machine makes water, but cannot reduce the amount of wastewater discharged during flushing. Therefore, it is not a very ideal technical solution, and the utilization rate of water is still low, which needs further improvement

Embodiment 1

[0031] See figure 1, the high-precision filtration system of this embodiment includes a first pretreatment filter element 1, a water source pipe 2, a filter 4, a water pump 3, a flushing valve 7, a return pipe 8, a second throttling device 6 and a first throttling device 5; The filter 4 is provided with an inlet, an outlet and a concentrated water port, and a filter element is arranged in the filter 4, and the filter element is a reverse osmosis membrane, so the filter 4 is also a reverse osmosis processor, and the high-precision filter system of this embodiment is a reverse osmosis net Water machine; the water inlet end of the return pipe 8 is connected to the concentrated water port of the filter 4, and the water outlet end is connected to the inlet of the filter 4; the return pipe 8 is provided with a water pump 3, a first pretreatment filter element 1 and a second throttling device 6 , the water outlet of the water pump 3 is connected to the inlet of the filter 4, the wate...

Embodiment 2

[0035] See figure 2 , this embodiment is basically the same as Embodiment 1, the difference is that this embodiment also includes a second pretreatment filter element 11, and the solid corrosion inhibitor 9 set in the first pretreatment filter element 1 is changed to the second pretreatment filter element 1 In the filter element 11, fiber filter material and / or activated carbon are also arranged in the second pretreatment filter element 11, and the second pretreatment filter element 11 is arranged in the return pipe 8; the water inlet of the second pretreatment filter element 11 communicates with the concentration of the filter 4 The water outlet, the water outlet of which communicates with the common water inlet of the first throttling device 5 , the second throttling device 6 and the flushing valve 7 .

[0036] The fiber filter material in the second pretreatment filter element 11 can effectively filter out the particles that may be carried in the concentrated water flowing...

Embodiment 3

[0038] See image 3 , this embodiment is basically the same as Embodiment 2, the difference is that: a water inlet valve 10 is added in the water source pipe 2, the water inlet valve 10 is a normally closed valve, and the water inlet valve 10 is in a closed state when the water purifier is shut down. It is possible to prevent leakage of the throttling device 5 during shutdown.

Abstract

The invention discloses a high-precision filtering system. The high-precision filtering system comprises a water source pipe, a preprocessing filter element, a water pump, a flushing valve, a return pipe, a filter, a first throttling device and a second throttling device, wherein the filter is provided with an inlet, an outlet and a concentration water port, and the filter is internally provided with a high precision filtering element; the water inlet end of the return pipe is communicated with the concentration water port of the filter, and the water outlet end of the return pipe is communicated the inlet of the filter; the return pipe is provided with the water pump, the preprocessing filter element and the second throttling device, the water outlet of the water pump is communicated with the inlet of the filter, and the inlet of the second throttling device is communicated with the concentration water port of the filter; the water inlet and the water outlet of the flushing valve are respectively communicated with the water inlet and the water outlet of the second throttling device; the water inlet of the first throttling device is communicated with the return pipe, the water outlet of the first throttling device is evacuated, and the water source pipe connected with a water source is communicated to the return pipe. The high-precision filtering system provided by the invention has the advantages that the flushing valve with the evacuating water outlet is not arranged, thus almost all flushing water is recycled, so that the water-saving effect is obvious.

Description

technical field [0001] The invention relates to a high-precision filtering system. Background technique [0002] With the continuous enhancement of people's drinking water health awareness, the use of household reverse osmosis water purifiers is becoming more and more common. The reason is that more and more people realize that this kind of water purifier can completely remove all toxic and harmful inorganic pollution in water. substances, organic pollutants, pathogenic bacteria and viruses. [0003] However, the water efficiency of traditional household reverse osmosis water purifiers is very low, and the reasons are as follows: [0004] 1. Usually, when water is produced, 3 / 4 of the total water intake is concentrated water, and it is discharged as waste water, and only 1 / 4 of the total water intake is made into pure water. In other words, when traditional reverse osmosis water purifiers produce water, the utilization rate of raw water is only a quarter. The specific met...
