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.

the second water inlet is connected with the first pipeline, so that the first pipeline can send water to the second water inlet, and the concentrated water inlet is communicated with the first water inlet, so that the concentrated water flowing out of the concentrated water inlet flows into the single-channel desalination assembly through the first water inlet; or,
the second water inlet is connected with the first pipeline, so that the first pipeline can supply water to the second water inlet, and the second water outlet is communicated with the second pipeline, so that the purified water flowing out of the second water outlet can flow into the second pipeline; or,
the first water outlet is communicated with the second water inlet, so that purified water flowing out of the first water outlet flows into the double-channel desalination assembly through the second water inlet, and the second pipeline is further used for outputting the purified water flowing out of the second water outlet.
9. The domestic water purification device of any one of claims 1 to 6, wherein the pipe system further comprises a pre-filter assembly located between the first pipe and the first water inlet, the pre-filter assembly comprising a PP cotton filter element and/or an activated carbon filter element.
10. The domestic water purification device of claim 9, wherein the activated carbon filter element comprises a scale inhibiting activated carbon filter element and a non-scale inhibiting activated carbon filter element.
11. The domestic water purification apparatus of any one of claims 1 to 6, further comprising a control assembly connected to the first valve assembly, the second valve assembly and the drive assembly, respectively;
and the control assembly is used for controlling the driving assembly and the first valve assembly to guide the purified water in the water storage tank to the first water outlet and controlling the second valve assembly to guide the wastewater flowing out from the first water inlet to the third pipeline when the accumulated purified water time of the single-channel desalting assembly reaches a preset time length.
12. The domestic water purification apparatus of claim 11, further comprising a conductivity acquisition component, wherein the control component is connected to the conductivity acquisition component, wherein the conductivity acquisition component is located at the first outlet of the single channel desalination component for acquiring the conductivity of the collected water;
the control assembly is further used for obtaining the conductivity collected by the conductivity collecting assembly, controlling the driving assembly and the first valve assembly to guide the purified water in the water storage tank to the first water outlet and controlling the second valve assembly to guide the wastewater flowing out from the first water inlet to the third pipeline when the conductivity does not reach the target conductivity and the accumulated purified water time of the single-channel desalination assembly reaches the preset time length.
13. The domestic water purification device of any one of claims 1 to 6, wherein the outlet direction of said second pipeline is connected to a plurality of outlet pipelines, and at least one of said outlet pipelines is provided with a heating element.
