Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water-electric structure between a filter element and a filter bottle based on an electric regeneration ion exchange membrane. Background Art

[0002] With the development of modern industry and the improvement of people's living standards, the requirements for water quality are getting higher and higher. Although traditional water treatment technologies, such as sedimentation, filtration, disinfection, etc., can improve water quality to a certain extent, they still have many shortcomings in removing pollutants dissolved in water, especially in heavy metal removal, sterilization and disinfection, etc., traditional technologies often fail to achieve ideal results.

[0003] In recent years, electro-regenerated ion exchange membrane technology has gradually attracted people's attention. This technology can stably and efficiently remove pollutants in water, especially heavy metals, without adding any chemicals. Compared with traditional reverse osmosis membrane technology, electro-regenerated ion exchange membrane technology wastes very little water and has multiple bactericidal and antiviral functions. Therefore, this technology is considered to be the only large-scale direct drinking water technology that can be applied in the world.

[0004] Traditional electrosorption filters are installed in filter bottles because the ion exchange and regeneration processes of the electrosorption filter require applying a DC voltage to the membrane electrode and the center tube electrode to generate DC power. This voltage is usually between 120 volts and 300 volts (up to 500 volts in industry). Higher voltages bring about problems and hidden dangers such as insulation safety, water channel energy consumption, and short circuits.

[0005] In view of this, this application is hereby filed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The filter bottle body 2 is provided with an electrode terminal component 1, in which a connector spring pin is provided, the electrode terminal component 1 is arranged at the front end or the middle part of the filter bottle body 2, in which an electrode negative contact head 27 and an electrode positive contact head 28 are provided, the membrane body electrode lead 12 is fixedly connected to the electrode negative contact head 27, and the central tube electrode lead 11 is fixedly connected to the electrode positive contact head 28,

This design not only improves the filtration efficiency, but also reduces the possible risk of water seepage or leakage.

[0037] Furthermore, the installation position of the electrode terminal component 1 is made far away from the water inlet and outlet 32 ​​of the filter bottle, which reduces the possibility of the insulation performance of the electrode negative contact 27 and the electrode positive contact 28 being degraded due to moisture.

[0039] When the connector socket 41 is energized, the DC voltage passes through the connector socket 41, the electrode negative contact 27 and the electrode positive contact 28, the central tube electrode lead 11 and the membrane electrode lead 12 in sequence, and then is transmitted to the central tube electrode line 21 and the electro-adsorption membrane electrode line 22.

[0040] By adopting a modular design of the filter bottle body 2, the filter bottle body 2 can be easily integrated into the water purifier frame 4. At the same time, the connection method between the electrode contact head and the connector socket 41 simplifies the installation process and reduces the maintenance difficulty.

[0044] The central tube water inlet hole 25 is opened at one end of the water outlet central tube 23 close to the front side of the filter bottle body 2, and the filter bottle water outlet 32 ​​is connected with the other end of the water outlet central tube 23, so that the pipeline length is increased, and the water resistance of the filter bottle is increased, thereby reducing the circulation between the filter elements when multiple electric adsorption filter elements are used in parallel, thereby reducing energy consumption.

[0045] Assuming the raw water TDS is 470PPM, the conductivity is 1000uS / CM, and the corresponding resistance is 1000Ω.cm.

[0046] If we let the length of the water path be 10cm, the total resistance is 10000Ω. Assuming the voltage is 200V, the current generated is 20 mA, and the wasted power is 4W.

[0047] Assuming that the length of the water channel is increased to 20cm, the total resistance is 20000Ω. Assuming the voltage is 200V, the current generated is 10 mA, and the wasted power is 2W.

[0048] By adopting the design of the secondary sealing end cap 14 and the secondary sealing ring 18, the sealing performance between the electrode lead and the filter bottle body 2 is significantly improved, effectively preventing water leakage and damage to electrical components, thereby ensuring the long-term stable operation of the hydropower structure.

[0049] For further information, see Figure 1 and Figure 4 A wire pressing plate 15 is also provided on the front side of the secondary sealing end cover 14, and the wire pressing plate 15 is threadedly connected to the secondary sealing end cover 14. The central tube electrode lead 11 and the membrane electrode lead 12 both pass through the wire pressing plate 15. An electrode lead seal 16 is also provided on the front side of the secondary sealing end cover 14. There are two electrode lead seals 16, which are respectively arranged at the connection ports where the central tube electrode lead 11 and the membrane electrode lead 12 penetrate into the filter bottle body 2. The central tube electrode lead 11 and the membrane electrode lead 12 are connected to the electrode terminal component 1 after passing through the electrode lead seal 16 and the wire pressing plate 15 in turn.

[0050] By providing components such as the wire pressing plate 15 and the electrode lead seal 16, the safety and reliability of the hydropower structure are further enhanced. These components can effectively prevent the loosening or falling off of the electrical components and reduce the potential safety hazards caused by poor contact.

[0051] In addition, reference Figure 6 and Figure 7 , and also includes an electrically regenerated ion exchange membrane, and an electric adsorption filter element (bipolar membrane filter element) based on the electrically regenerated ion exchange membrane, which is composed of an electrode group and a bipolar membrane located between two electrodes, the bipolar membrane is composed of a cation exchange membrane and an anion exchange membrane bonded together, and a flow channel is formed between the bipolar membrane and the adjacent bipolar membrane or electrode.

[0052] The main working process of the electric adsorption filter element based on the electric regeneration ion exchange membrane includes the desalination process and the regeneration process:

[0053] In the desalination process, the cation membrane of the bipolar membrane faces the positive electrode, and the raw water is desalinated in the flow channel formed between the two bipolar membranes. Figure 6 shown.

[0054] Anions in the raw water, such as Cl-, move toward the positive electrode, replacing OH- in the anion exchange membrane on the left, and OH- enters the flow channel; at the same time, cations in the raw water, such as Na+, move toward the negative electrode, replacing H+ ions in the cation exchange membrane of the bipolar membrane on the right, and H+ enters the flow channel; H+ and OH- undergo a neutralization reaction in the flow channel to generate water, thereby removing salt from the raw water, and pure water flows out from the end of the flow channel.

[0055] After desalination has been carried out for a period of time, the bipolar membrane filter element needs to be regenerated by reverse polarity, and the bipolar membrane filter element is reversely energized to release the water ions adsorbed on the bipolar membrane.

[0056] At this time, if Figure 7 As shown, the interface layer of the cation membrane and the anion membrane of the bipolar membrane produces OH- and H+ ions under the electric field, and the cations such as Na+ inside the cation membrane of the bipolar membrane are replaced by H+ ions and move toward the negative electrode, and the anions such as Cl- in the anion membrane of the bipolar membrane are replaced by OH- and move toward the positive electrode, and Na+ and Cl- enter the flow channel, realizing the regeneration process of the bipolar membrane filter element.

[0057] Working principle:

[0058] When in use, due to the reasonable layout of the central tube electrode lead 11 and the membrane body electrode lead 12, as well as the setting of the electrode terminal component 1, the entire hydropower structure is more compact and easier to manage. This design not only improves the filtration efficiency, but also reduces the possible risk of water seepage or leakage.

[0059] Since the installation position of the electrode terminal component 1 is far away from the water inlet and outlet 32 ​​of the filter bottle, the electrode negative contact 27 and the electrode positive contact 28 are less susceptible to moisture, resulting in a decrease in insulation performance.

[0060] Because of the design of the secondary sealing end cap 14 and the secondary sealing ring 18, the sealing performance between the electrode lead and the filter bottle body 2 is significantly improved, effectively preventing water leakage and damage to electrical components, thereby ensuring the long-term stable operation of the hydropower structure.

[0061] Because the central tube water inlet hole 25 is opened at one end of the water outlet central tube 23 close to the front side of the filter bottle body 2, the filter bottle water outlet 32 ​​is connected to the other end of the water outlet central tube 23, so that the pipeline length is increased, and the water resistance of the filter bottle is increased, thereby reducing the circulation between the filter elements when multiple electric adsorption filter elements are used in parallel, thereby reducing energy consumption.

[0062] Because the filter bottle body 2 adopts a modular design, the filter bottle body 2 can be easily integrated into the water purifier frame 4. At the same time, the connection method between the electrode contact head and the connector socket 41 simplifies the installation process and reduces the maintenance difficulty. This design allows users to operate and maintain the entire water and electricity structure more easily.

[0063] The provision of components such as the wire pressing plate 15 and the electrode lead seal 16 further enhances the safety and reliability of the hydropower structure. These components can effectively prevent the electrical components from loosening or falling off, and reduce potential safety hazards caused by poor contact.
