specific Embodiment approach 1

[0027] Specific implementation mode one: combine Figure 1-Figure 4 Explain that a bucket-less water-saving water purifier in this embodiment includes an N-level primary filter device, a booster pump 9, an osmotic membrane module system, and a control circuit box 24; the osmotic membrane module system adopts a two-stage combination That is, the concentrated water of the osmotic membrane modules of the first stage is combined and connected to the water inlet of the osmotic membrane modules of the second stage, and the pure water ports of the osmotic membrane modules of the two stages are combined and then discharged.

[0028] The beneficial effects of this embodiment are: ordinary reverse osmosis pure water machines and nanofiltration membrane pure water machines only use a single reverse osmosis or nanofiltration membrane original, in order to avoid concentration polarization on the surface of the reverse osmosis membrane or nanofiltration membrane and the Therefore, the water...

specific Embodiment approach 2

[0029] Specific implementation mode two: combination Figure 1-Figure 4 Note, the difference between this embodiment and specific embodiment 1 is that the permeable membrane module system adopts a 2:1 two-stage combination, that is, the number of membrane elements or the rated total water production of the first-stage permeable membrane module 10 is the second The number of membrane elements in the permeation membrane module 12 or the rated total water production is twice as large.

[0030] The beneficial effect of this embodiment is: the osmotic membrane module system adopts the form of 2:1 two-stage combination, which can make the water flow and working pressure of each membrane module more coordinated, and make the working condition of the reverse osmosis membrane or nanofiltration membrane better.

[0031] Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0032] Specific implementation mode three: combination Figure 1-Figure 4 Note, the difference between this embodiment and the first embodiment is that the permeable membrane module is a reverse osmosis membrane module.

[0033]The beneficial effect of this embodiment is: the diameter of the micropores on the surface of the reverse osmosis membrane module is generally between 0.5 and 10 nm, and it can intercept substances larger than 0.0001 microns. It is the finest membrane separation product, and it can effectively intercept all dissolved salts. And organic matter with a molecular weight greater than 100 while allowing water molecules to pass through. The desalination rate of the reverse osmosis membrane to high-valent ions and complex monovalent ions can exceed 99%, and the desalination rate of monovalent ions such as sodium ions, potassium ions, and chloride ions is slightly lower, and can also exceed 98% (the longer the reverse osmosis membrane is used , the more times o...

Abstract

The invention discloses a bucket-free water-saving water purifier, relates to a water-saving water purifier, in particular relates to a water purifier by adopting a reverse osmosis membrane and a nanofiltration membrane and belongs to the field of water purification. The problems that a wastewater ratio is large, water is wasted, a pressure water storage bucket is needed to be arranged and different water quality requirements of household water for kitchen and life drinking water cannot be simultaneously met in a conventional water purification machine or water purifier are solved. The water purifier comprises an N-stage primary filtering device, a booster pump, a permeable membrane component system and a control circuit box, wherein the permeable membrane component system is in a two-section combined mode; a water purification pipeline and a flushing pipeline of the primary filtering device are arranged. The water purifier is used for purifying running water.

Description

technical field [0001] The invention relates to a water-saving water purifier, in particular to a water purifier using a reverse osmosis membrane and a nanofiltration membrane, belonging to the field of water purification. Background technique [0002] Due to the high filtration accuracy of reverse osmosis membrane or nanofiltration membrane, it can effectively remove various toxic and harmful pollutants such as fine particles, organic matter, soluble salts, heavy metal ions, bacteria, viruses and other microorganisms in water, pesticide residues, etc. At present, water purifiers using reverse osmosis membrane or nanofiltration have been widely used, especially for households to further treat tap water, but ordinary reverse osmosis pure water machines or nanofiltration water purifiers have the following disadvantages during use and bugs: [0003] (1) Waste water is relatively high, not water-saving. According to the permeability characteristics of the reverse osmosis membr...
