Fig. 1 is a schematic structural diagram of the household water purifying device in the embodiment.

Referring to fig. 1, the household water purification apparatus includes a single-channel desalination module 100 and a pipeline system 200.

Specifically, as shown in fig. 1, the single-channel desalination assembly 100 includes a first water inlet 110 and a first water outlet 120, and the single-channel desalination assembly 100 performs a purification treatment on water flowing in from the first water inlet 110 to obtain purified water, and the purified water flows out through the first water outlet 120.

It will be appreciated that the single-channel desalination assembly 100 uses only one water inlet and one water outlet for the purification of water flowing therethrough, and thus may be referred to as a single-channel desalination assembly.

In some embodiments, the single channel desalination assembly 100 can, of course, also include other water inlets and/or outlets. For example, when the single-channel desalination assembly 100 is flushed and regenerated, the generated wastewater can be discharged through the water outlet. When the single-channel desalination assembly 100 is purifying water flowing through, the water inlets and/or outlets other than the first water inlet 110 and the first water outlet 120 can be closed, thereby forming a single-channel structure.

The single channel desalination module 100 may not discharge wastewater when purifying water flowing therethrough. Through adopting the desalination subassembly of single current way to carry out the water purification, the water that gets into single current way desalination subassembly 100 can be followed the delivery port and discharged, obtains purification treatment simultaneously, does not produce waste water in this process, has improved the utilization ratio of water.

In some embodiments, the single-channel desalination assembly 100 comprises a physisorption desalination cartridge and/or a chemisorption desalination cartridge.

Illustratively, the chemisorptive desalination cartridge can include at least one of an ion exchange (IX) resin cartridge, a bipolar membrane (Biopolar, BP) electrodeionization cartridge.

Illustratively, the physisorption desalination filter element may include at least one of a Capacitive Desalination (CDI) filter element, a Membrane Capacitive Desalination (MCDI) filter element.

Specifically, the capacitive desalination filter element, the membrane capacitive desalination filter element, the bipolar membrane electrodeionization filter element and the like can cause the directional migration of cations and anions when being electrified so as to realize the purification treatment of water, and the filter elements can be called as electrically driven desalination filter elements.

Specifically, as shown in fig. 2 and 3, a schematic diagram of a structure of a bipolar membrane electrodeionization filter cartridge 900 is shown.

As shown in fig. 2 and 3, the bipolar membrane electrodeionization filter cartridge 900 includes one or more pairs of electrodes 910, and at least one bipolar membrane 920 or a plurality of spaced-apart bipolar membranes 920 is disposed between at least one pair of electrodes 910. Wherein, bipolar membrane 920 includes cation exchange membrane 921 and anion exchange membrane 922, and cation exchange membrane 921 and anion exchange membrane 922 set up relatively, compound together. For example, the bipolar membrane 920 can be produced by a hot press molding method, a bonding molding method, a casting molding method, an anion and cation exchange radical method, an electrodeposition molding method, or the like. Specifically, there is no space between the cation exchange membrane 921 and the anion exchange membrane 922 on one bipolar membrane 920, for example, water does not pass between the cation exchange membrane 921 and the anion exchange membrane 922 on the same bipolar membrane 920 when flowing through the bipolar membrane electrodeionization filter cartridge 900.

As shown in fig. 2 and 3, the electrodes 910 include a first electrode 911 and a second electrode 912, wherein the first electrode 911 is disposed opposite to a cation exchange membrane 921 of the bipolar membrane 920 adjacent to the first electrode 911, and the second electrode 912 is disposed opposite to an anion exchange membrane 922 of the bipolar membrane 920 adjacent to the second electrode 912.

Fig. 2 is a schematic diagram showing the operation principle of the bipolar membrane electrodeionization filter element 900 in the process of purifying water. Here, the potential of the first electrode 911 is higher than that of the second electrode 912, that is, a voltage in a forward direction is applied between the first electrode 911 and the second electrode 912. At this time, anions such as chloride ions in the raw water to be purified move towards the first electrode 911, and replace OH < - > in the anion exchange membrane 922 in the direction of the first electrode 911, and the OH < - > enters the flow channel between the adjacent bipolar membranes 920; meanwhile, cations such as Na + in the raw water move towards the second electrode 912 to replace H + in the cation exchange membrane 921 in the direction of the second electrode 912, and the H + enters the flow channel; h + and OH-are subjected to neutralization reaction in the flow channel to generate water, so that the salt in the raw water is removed, and purified pure water flows out from the tail end of the flow channel.

As shown in fig. 3, when a voltage in the opposite direction is applied between the first electrode 911 and the second electrode 912, so that the potential of the first electrode 911 is lower than that of the second electrode 912, OH "and H + ions are generated on the surfaces of the cation exchange membrane 921 and the anion exchange membrane 922 of the bipolar membrane 920 under the action of an electric field, cations such as Na + inside the cation exchange membrane 921 are replaced by H + ions and move toward the first electrode 911 at a low potential, anions such as chloride ions in the anion exchange membrane 922 are replaced by OH" and move toward the second electrode 912 at a high potential, and the cations such as Na + and the anions such as chloride ions enter the flow channel and can be washed out by water flowing through the bipolar membrane electrodeionization filter 900. Therefore, when the power is off or reverse voltage is applied to the desalting filter cores such as the bipolar membrane electrodeionization filter core 900 and the like, cations such as Na < + > and the like and anions such as chloride ions and the like adsorbed on the bipolar membrane 920 can be released, so that salt substances of the bipolar membrane electrodeionization filter core can be washed out by water, and regeneration is realized; water carrying cations such as Na + and anions such as chloride ions can be called concentrated water.

In some embodiments, the piping system 200 includes a post-filter assembly disposed at the outlet of the second pipe 220, the post-filter assembly including a microfiltration cartridge and/or an activated carbon cartridge.

In some embodiments, the control module 300 is further configured to control the first valve assembly 250 to guide the water delivered by the first pipeline 210 into the salt storage assembly 240 when the accumulated water purification time of the single-channel desalination assembly 100 reaches a preset time, and the salt substances in the salt storage assembly 240 are dissolved in the guided water to obtain salt water; the control assembly 300 is further configured to control the third valve assembly 270 to direct the brine to the first water outlet 120, and the brine flowing from the first water outlet 120 regenerates the single-channel desalination assembly 100 to obtain wastewater, and the wastewater flows out through the first water inlet 110; the control assembly 300 is also used to control the second valve assembly 260 to direct the wastewater flowing out through the first water inlet 110 into the third pipeline 230.
