Abstract
Description
Technical Field
[0001] This application relates to the field of water purification equipment technology, and in particular to a water purification device and water purification equipment. Background Technology
[0002] With economic development and improved living standards, consumers are paying more attention to healthy drinking water and have increasingly higher requirements for it. Therefore, more and more consumers are using water purification equipment to filter tap water before use or drinking. Currently, the mainstream water purification technologies are ultrafiltration and RO reverse osmosis filtration. However, ultrafiltration is prone to clogging after prolonged use, and clogged ultrafiltration filters are difficult to clean and costly to replace. RO reverse osmosis membranes, on the other hand, have drawbacks such as the difficulty in obtaining the necessary materials, and long-term consumption of RO-filtered pure water can lead to mineral loss in the body.
[0003] With the development of electro-adsorption technology, it has received increasing attention in the field of water purification. Electro-adsorption technology refers to obtaining fresh water resources by adsorbing salt ions in water. The principle is that after the electrode plate material is energized, it forms an electric field perpendicular to the electrode plate. Charged particles in the water to be treated are deflected towards the electrode plate under the action of the electric field until the ions are adsorbed onto the electrode plate, thus achieving desalination of the water to be treated. After the adsorption on the electrode plate reaches saturation, the energization of the electrode plate is stopped and the positive and negative electrodes are short-circuited, so that the ions return to the solution, thus regenerating the electrode plate.
[0004] Electroadsorption technology has become increasingly mature, evolving from initial use of carbon aerogel as an ion adsorption material to carbon cloth and ultimately carbon-based materials. With the emergence of new electrode plate materials, many adsorption electrode plates have been developed using conductive agents and active materials in specific ratios. However, all of these electrode plates are fixed, with limited adsorption capacity, requiring regeneration for repeated adsorption and thus hindering continuous desalination. Therefore, flowing electrode plate electroadsorption technology has been developed. Compared to fixed electrode plates, flowing electrode plates can desorb adsorbed salt ions outside the device, achieving continuous desalination. However, traditional flowing electrode plates have a small contact area with the water to be treated, resulting in low adsorption efficiency and impacting the overall water purification efficiency of the water purification equipment.

[0060] See Figure 1 , Figure 2 and Figure 3 An embodiment of this application provides a water purification device including a first electrode assembly 10, a water guide 30, and a second electrode assembly 50. The first electrode assembly 10, the water guide 30, and the second electrode assembly 50 are stacked sequentially along a first direction X. In actual use, the first direction X can be the direction of gravity, i.e. Figure 2 The arrangement of the components from top to bottom allows the first electrode assembly 10, the water guide 30, and the second electrode assembly 50 to press against each other, facilitating assembly and improving water purification.
[0061] Specifically, the first electrode assembly 10 is used to connect to the negative terminal of an external power source and has a first electrode liquid flowing inside it. When the first electrode assembly 10 is connected to the negative terminal of the external power source, electrons from the external power source flow from the negative terminal to the second electrode assembly 50, thereby causing the particles in the first electrode assembly 10 and the first electrode liquid inside the first electrode assembly 10 to carry a negative charge.
[0062] The second electrode assembly 50 is used to connect to the positive terminal of an external power source, and a second electrode liquid flows inside it. When the second electrode assembly 50 is connected to the positive terminal of an external power source, electrons in the second electrode assembly 50 and the second electrode liquid inside the second electrode assembly 50 flow to the positive terminal of the external power source, thereby causing the particles in the second electrode assembly 50 and inside the second electrode assembly 50 to carry a positive charge.
[0063] When the first electrode assembly 10 and the second electrode assembly 50 are simultaneously connected to the negative and positive terminals of an external power source, an electric field is formed between the second electrode assembly 50 and the first electrode assembly 10. The water guide 30 is located within this electric field, and the water guide 30, the first electrode assembly 10, and the second electrode assembly 50 form a water channel 31, through which water to be treated flows. Under the influence of the electric field formed by the first electrode assembly 10 and the second electrode assembly 50, cations in the water to be treated located inside the water channel 31 can enter the first electrode liquid, and anions can enter the second electrode liquid, thereby achieving desalination of the water to be treated. The continuous desalination of the water to be treated is achieved through the flow of the first and second electrode liquids.
[0064] The water flow channel 31 extends in a tortuous manner on the surface perpendicular to the first direction X, thereby increasing the length of the water flow channel 31 and increasing the contact area between the first electrode assembly 10 and the second electrode assembly 50 and the water to be treated. The flow time of the water to be treated in the water flow channel 31 will also increase. The longer the flow time of the water to be treated in the water flow channel 31, the longer the ions in the water to be treated will be affected by the electric field. This results in a greater number of cations entering the first electrode liquid and anions entering the second electrode liquid, effectively improving the water purification efficiency of the water to be treated.
[0065] In some embodiments of this application, see [reference] Figure 2 , Figure 3 , Figure 4 and Figure 5 The first electrode assembly 10 includes a first electrode plate 12, a first electrode liquid guide plate 13, and a cation exchange membrane 14. The first electrode plate 12, the first electrode liquid guide plate 13, and the cation exchange membrane 14 are stacked sequentially on one side of the water flow element along a first direction X. The first electrode plate 12 is connected to the negative terminal of the power supply, thereby making the first electrode plate 12 negatively charged. The first electrode liquid flows in the guide plate of the first electrode plate 12. Cations in the water to be treated are attracted by the negative charge of the first electrode plate 12, pass through the cation exchange membrane 14 into the first electrode liquid guide plate 13, and finally enter the first electrode liquid in the first electrode plate 12 and are discharged from the water purification device with the first electrode liquid.
[0066] The first electrode liquid guide plate 13 has a first guide hole 15 extending through the first direction X. The first guide hole 15 extends in a tortuous manner on the surface of the first guide plate. The first electrode plate 12 and the cation exchange membrane 14 respectively cover the two opposite ends of the first guide hole 15 in the first direction X. The first electrode plate 12, the first electrode liquid guide plate 13, and the cation exchange membrane 14 are arranged to form a first flow channel 11 for the flow of the first electrode liquid.
[0067] Furthermore, the second electrode assembly 50 includes a second electrode plate 52, a second electrode liquid guide plate 53, and an anion exchange membrane 54. The anion exchange membrane 54, the second electrode liquid guide plate 53, and the second electrode plate 52 are stacked sequentially along the first direction X on the other side of the water guide member 30. That is, along the first direction X... Figure 2 The components stacked from top to bottom are: first electrode plate 12, first electrode liquid guide plate 13, cation exchange membrane 14, water guide plate 30, second electrode plate 52, second electrode liquid guide plate 53, and anion exchange membrane 54.
[0068] The second electrode liquid guide plate 53 has a second guide hole 55 that extends through the first direction X. The second electrode plate 52 and the anion exchange membrane 54 respectively cover the two opposite ends of the second guide hole 55 in the first direction X. The second electrode plate 52, the second electrode liquid guide plate 53, and the anion exchange membrane 54 are arranged to form a second flow channel 51 for the flow of the second electrode liquid.
[0069] Furthermore, the water guide member 30 has a water guide hole 32 extending through the water in the first direction X. The water guide hole 32 extends in a tortuous manner on the surface of the water guide member 30. The cation exchange membrane 14 and the anion exchange membrane 54 respectively cover the opposite ends of the water guide hole 32 in the first direction X. The cation exchange membrane 14, the anion exchange membrane 54, and the water guide member 30 form a water flow channel 31. Optionally, the width of the water guide hole 32 is 6.4 mm.
[0070] Thus, after the tortuous water guide hole 32 forms a water channel 31 with the cation exchange membrane 14 and the anion exchange membrane 54, the water channel 31 also exhibits a tortuous extension. After the first electrode plate 12 and the second electrode plate 52 are energized, under the action of the electric field formed by the first electrode plate 12 and the second electrode plate 52, the cations in the water to be treated in the water channel 31 will enter the first electrode liquid in the first channel 11 through the cation exchange membrane 14, while the anions will enter the second electrode liquid in the second channel 51 through the anion exchange membrane 54, thereby achieving the effect of desalination of the water to be treated.
[0071] In some embodiments of this application, after a first flow channel 11 is formed inside the first electrode assembly 10 through the first electrode plate 12, the first electrode liquid guide plate 13, and the cation exchange membrane 14, the first electrode liquid can flow along the first flow channel 11, and the projection of the first flow channel 11 on the surface perpendicular to the first direction X is tortuous and extended. In this way, the tortuous first flow channel 11 further increases the contact area between the first electrode liquid and the water to be treated, thereby increasing the number of cations entering the first electrode liquid from the water to be treated, and finally improving the water purification efficiency of the water to be treated.
[0072] Furthermore, after a second flow channel 51 is formed inside the second electrode assembly 50 through the second electrode plate 52, the second electrode liquid guide plate 53, and the anion exchange membrane 54, the second electrode liquid can flow along the second flow channel 51. The projection of the second flow channel 51 on the surface perpendicular to the first direction X is tortuous and extended. Similar to the first flow channel 11, the tortuous second flow channel 51 can increase the contact area between the second electrode liquid and the water to be treated, thereby increasing the number of anions entering the second electrode liquid from the water to be treated and improving the water purification efficiency of the water to be treated.
[0073] It is understood that in some other embodiments, one of the first flow channel 11 and the second flow channel 51 may extend in a tortuous manner while the other extends in a straight line. The shapes of the first flow channel 11 and the second flow channel 51 can be selected according to actual usage requirements and are not limited here.
[0074] In one specific embodiment, the projection of the first flow channel 11 onto the water guide member 30 at least partially overlaps with the water flow channel 31. The greater the degree of overlap between the projection of the first flow channel 11 onto the water guide member 30 and the water flow channel 31, the larger the contact area between the first electrode liquid and the water to be treated within the first flow channel 11, thereby improving the purification efficiency of the water to be treated. Furthermore, the projection of the second guide member onto the water guide member 30 at least partially overlaps with the water flow channel 31, thereby increasing the contact area between the second electrode liquid and the water to be treated, and further improving the purification efficiency of the water to be treated.
[0075] Specifically, both the first flow channel 11 and the second flow channel 51 include multiple electrode liquid sub-channels arranged parallel to the second direction Y. Each electrode liquid sub-channel extends longitudinally along the third direction Z. The electrode liquid sub-channels are connected end to end. The first direction X, the second direction Y, and the third direction Z intersect each other but are not coplanar, thus making the first flow channel 11 and the second flow channel 51 serpentine in shape. The water flow channel 31 also includes multiple water sub-channels arranged parallel to the second direction Y. Each water sub-channel extends longitudinally along the third direction Z. The water sub-channels are connected end to end. Each water sub-channel is aligned with one of the electrode liquid sub-channels and arranged parallel to each other, so that the projections of the first flow channel 11 and the second flow channel 51 on the water guide 30 can mostly coincide with the water flow channel 31.
[0076] In some embodiments, see Figure 3 To facilitate the installation of the cation exchange membrane 14, the water guide 30 has a first stepped groove 33 on the side facing the first electrode assembly 10. The cation exchange membrane 14 is placed in the stepped groove. Thus, the first stepped groove 33 not only facilitates the installation of the cation exchange membrane 14, but also protects the cation exchange membrane 14 by wrapping its edges, reducing the probability of damage to the cation exchange membrane 14.
[0077] Furthermore, to facilitate the installation of the anion exchange membrane 54, the water guide 30 has a second stepped groove 34 on the side facing the second electrode assembly 50. The anion exchange membrane 54 is disposed within the second stepped groove 34, thereby providing edge protection for the anion exchange membrane 54 through the second stepped groove 34. The water guide hole 32 extends through the first stepped groove 33 to the second stepped groove 34, thus forming a water flow channel 31 with the cation exchange membrane 14 and the anion exchange membrane 54 surrounding the water guide hole 32.
[0078] In some specific embodiments, the water guide 30 has an inlet 35 at one end and an outlet 36 at the other end in the second direction Y. The inlet 35 and outlet 36 are respectively connected to the two ends of the guide hole in its longitudinal direction. Water to be treated is input into the water channel 31 through the inlet 35, and desalinated treated water is input through the outlet 36. By placing the inlet 35 and outlet 36 on opposite sides of the water guide 30 in the second direction Y, the stacking and cooperation between the water guide 30 and the first electrode assembly 10 and the second electrode assembly 50 can be maintained, facilitating the interconnection of the water purification equipment with other external devices.
[0079] In some embodiments, the first electrode assembly 10 further includes a first protective member 16, which is disposed on the side of the first electrode plate 12 away from the first electrode liquid guide plate 13, thereby protecting the surface of the first electrode plate 12. Further, the second electrode assembly 50 also includes a second protective member 56, which is disposed on the side of the second electrode plate 52 away from the second electrode liquid guide plate 53, thereby protecting the surface of the second electrode plate 52.
[0080] In some specific embodiments, the water purification device further includes a first input pipe 17 and a first output pipe 18. The first input pipe 17 and the end of the first output pipe 18 externally mounted both extend out of the first protective member 16, and their other ends pass through the first protective member 16, the first electrode plate 12, and the first guide hole 15. A first input port 19 is provided on the circumferential sidewall of the first input pipe 17, located at one end of the first guide hole 15 in its longitudinal direction. A first output port 20 is provided on the circumferential sidewall of the first output pipe 18, located at the other end of the first guide hole 15 in its longitudinal direction.
[0081] In actual use, the first electrode liquid in the external first electrode liquid storage device is input into the first flow channel 11 through the first output port 20 of the first input pipe 17. After the first electrode liquid in the first flow channel 11 absorbs the cations of the water to be treated, it is then input back into the external first electrode liquid storage device through the first output port 20 and the first output pipe 18.
[0082] Extending one end of the first input pipe 17 and the first output pipe 18 out of the first protective member 16 facilitates connection with an external first electrode liquid storage device. Connecting the first flow channel 11 via the first input port 19 of the first input pipe 17 and the first output port 20 of the first output pipe 18 eliminates the need for additional openings on the first electrode liquid guide, making the overall water purification device more compact and reducing the number of sealing points, thereby reducing the risk of first electrode liquid leakage. Furthermore, since the first input pipe 17 and the first output pipe 18 pass through the first protective member 16, the first electrode plate 12, and the first electrode liquid guide, they can be positioned using the first input pipe 17 during installation, increasing installation flexibility and convenience.
[0083] In some embodiments, the water purification device further includes a second input pipe 57 and a second output pipe 58. One end of both the second input pipe 57 and the second output pipe 58 extends out of the first protective member 16, and the other end passes through the first protective member 16, the first electrode plate 12, the first electrode liquid guide plate 13, the water guide member 30, the second protective member 56, the second electrode plate 52, and the second guide hole 55. A second input port 59 is provided on the circumferential sidewall of the second input pipe 57, located at one end of the second guide hole 55 in its longitudinal direction. A second output port 60 is provided on the circumferential sidewall of the second output pipe 58, located at the other end of the second guide hole 55 in its longitudinal direction.
[0084] The functions of the second input pipe 57 and the second output pipe 58 are the same as those of the first input pipe 17 and the first output pipe 18, and will not be repeated here. In this embodiment, since the second input pipe 57, the second output pipe 58, the first input pipe 17, and the first output pipe 18 all extend from the first protective member 16, the interfaces of the second input pipe 57, the second output pipe 58, the first input pipe 17, and the first output pipe 18 are all located on the same side of the water purification device, so as to facilitate the installation of the second input pipe 57, the second output pipe 58, the first input pipe 17, and the first output pipe 18 with other equipment.
[0085] Furthermore, the second input tube 57, the second output tube 58, the first input tube 17, and the first output tube 18 are all integrally formed with the second protective component 56. Thus, when installing the second protective component 56, the second input tube 57, the second output tube 58, the first input tube 17, and the first output tube 18 can be directly installed in place. Then, the second electrode plate 52, the second electrode liquid guide plate 53, the anion exchange membrane 54, the water guide plate 30, the cation exchange membrane 14, the first electrode liquid guide plate 13, and the first electrode plate 12 can be stacked sequentially along the second input tube 57, etc.
[0086] It is understandable that the second input pipe 57, the second output pipe 58, the first input pipe 17, and the first output pipe 18 can pass directly through the water guide hole 32 when passing through the water guide member 30, or they can have separate holes for each pipe to pass through. The first electrode plate 12, the second electrode plate 52, the first protective member 16, and the second protective member 56 are each provided with four through holes for the second input pipe 57, the second output pipe 58, the first input pipe 17, and the first output pipe 18 to pass through, respectively.
[0087] In some other embodiments, the protruding ends of the second input pipe 57 and the second output pipe 58 may also be located on the second protective member 56. Specifically, the water purification device further includes a second input pipe 57 and a second output pipe 58, one end of which extends out of the second protective member 56, and the other end of which passes through the second protective member 56, the second electrode plate 52, and the second guide hole 55. A second input port 59 is provided on the circumferential sidewall of the second input pipe 57, located at one end of the second guide hole 55 in its longitudinal direction. A second output port 60 is provided on the circumferential sidewall of the second output pipe 58, located at the other end of the second guide hole 55 in its longitudinal direction. That is, the interface of the second input pipe 57 and the second output pipe 58 is located at the other end of the water purification device away from the first input pipe 17 and the first output pipe 18, thereby achieving more flexible installation according to actual installation requirements.
[0088] In some embodiments, since the first electrode plate 12 is covered by the first protective member 16 and the first electrode liquid guide plate 13 on both sides of the first direction X, in order to connect the first electrode plate 12 to an external power source, one end of the first electrode plate 12 extends out of the first protective member 16 and the first electrode liquid guide plate 13 in the second direction Y, and by connecting the extended part of the first electrode plate 12 to the power source, the first electrode plate 12 can be charged.
[0089] Similarly, the second electrode plate 52 extends a second protective member 56 and a second electrode liquid guide plate 53 at one end of the second direction Y that intersects the first direction X, so that the power supply is connected through the extended part of the second electrode plate 52, so that the second electrode plate 52 is charged and forms an electric field with the first electrode plate 12.
[0090] It is understood that in some other embodiments, holes may be made in the first protective member 16 and / or the second protective member 56 to connect the first electrode plate 12 and / or the second electrode plate 52 to an external power source.
[0091] In some embodiments of this application, in order to prevent leakage of the first electrode liquid, the second electrode liquid, and the water to be treated, a first sealing member 70 is provided between the first electrode plate 12 and the first electrode liquid guide. The first sealing member 70 seals the gap between the first electrode plate 12 and the first electrode liquid guide to prevent leakage of the first electrode liquid.
[0092] Meanwhile, a second sealing element 71 is provided between the first electrode liquid guide plate 13 and the water guide element 30. The second sealing element 71 seals the gap between the first electrode liquid guide plate 13 and the water guide element 30 to prevent leakage of the water to be treated or the first electrode liquid.
[0093] Furthermore, a third sealing element 72 is provided between the water guide element 30 and the second electrode liquid guide plate 53 to seal the gap between the water guide element 30 and the second electrode liquid guide plate 53, thereby preventing leakage of the water to be treated or the second electrode liquid.
[0094] Furthermore, a fourth sealing element 73 is provided between the second electrode liquid guide plate 53 and the second electrode plate 52 to seal the gap between the second electrode liquid guide plate 53 and the second electrode plate 52, thereby preventing leakage of the second electrode liquid.
[0095] In some embodiments of this application, the above-mentioned sealing element requires sufficient pressure to maintain the sealing effect. For this purpose, the water purification device also includes bolts and nuts. The first electrode assembly 10 has a first fastening hole 21 that passes through the first direction X. The water guide 30 has a second fastening hole 37 that passes through the first direction X. The second electrode assembly 50 has a third fastening hole 61 that passes through the first direction X. The bolt passes through the first fastening hole 21, the second fastening hole 37 and the third fastening hole 61 and is threadedly connected to the nut.
[0096] The first fastening hole 21 passes through the first protective component 16, the first electrode plate 12, and the first electrode liquid guide component in sequence, and the second fastening hole 37 passes through the second electrode liquid guide component, the second electrode plate 52, and the second protective component 56 in sequence. Thus, when the bolt and nut are tightened, the bolt and nut will fix the first protective component 16, the first electrode plate 12, the first electrode liquid guide component, the water guide component 30, the second electrode liquid guide component, the second electrode plate 52, and the second protective component 56.
[0097] Furthermore, there are multiple first fastening holes 21, which are arranged around the edge of the first electrode assembly 10. There are multiple second fastening holes 37, which correspond one-to-one with the multiple first fastening holes 21 and are arranged around the edge of the water guide 30. There are multiple third fastening holes 61, which correspond one-to-one with the multiple second fastening holes 37 and are arranged around the edge of the second electrode assembly 50.
[0098] Thus, the edges of the first protective component 16, the first electrode plate 12, the first electrode liquid guide component, the water guide component 30, the second electrode liquid guide component, the second electrode plate 52, and the second protective component 56 can be fixed through multiple first fastening holes 21, multiple second fastening holes 37, and multiple third fastening holes 61 to ensure that the fastening force in the planar direction is evenly distributed circumferentially, thereby ensuring the sealing effect of the first sealing component 70, the second sealing component 71, the third sealing component 72, and the fourth sealing component 73.
[0099] This application also provides a water purification device, including the water purification device as described in any of the above embodiments. Since the water purification device includes all the technical features of the above-mentioned water purification device, it possesses all the technical effects of the above-mentioned water purification device, which will not be repeated here.
[0100] The above-mentioned water purification device has at least the following advantages:
[0101] The projection of the water flow channel 31 onto the surface perpendicular to the first direction X extends in a tortuous manner, thereby increasing the length of the water flow channel 31 and increasing the contact area between the first electrode assembly 10 and the second electrode assembly 50 and the water to be treated. The flow time of the water to be treated in the water flow channel 31 also increases. The longer the flow time of the water to be treated in the water flow channel 31, the longer the ions in the water to be treated are affected by the electric field. This results in a greater number of cations entering the first electrode liquid and anions entering the second electrode liquid, effectively improving the water purification efficiency of the water to be treated.
[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0103] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
