Traditional descaling methods mainly include chemical softening, ion exchange, and membrane separation. In traditional electro-adsorption descaling, scale is not easily removed after the flat plate electrode comes into contact with the water flow. The scale also makes it difficult for ions in the circulating water to react with the electrode, thus affecting the descaling efficiency. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0018] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0019] Furthermore, in this application, directional terms such as "upper," "lower," "left," and "right" may be defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms can be relative concepts, used for relative description and clarification, and may change accordingly depending on the orientation of the components in the accompanying drawings.

[0020] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, the term "coupled" can refer to an electrical connection that enables signal transmission.

[0021] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0022] This application provides an electrochemical adsorption vibration module, such as Figure 1-6As shown, the device includes several cathode plates, several anode plates 2, a first mounting member 4 for mounting the cathode plates, and a second mounting member 5 for mounting the anode plates 2. The first mounting member 4 and the second mounting member 5 are fixedly connected to external equipment via a mounting base 6. The cathode plates are fixed below the first mounting member 4 and perpendicular to it, while the anode plates 2 are fixed below the second mounting member and perpendicular to it. When circulating water needs to be treated, the cathode plates and anode plates 2 are inserted into the circulating water to be treated and, when energized, work together to form an electric field. Subsequently, under the action of the electric field, cations in the circulating water (such as calcium ions, magnesium ions, etc.) are adsorbed onto the cathode plates 1 and form solid scale (whose composition is generally calcium carbonate or other solids), thus achieving descaling of the circulating water.

[0023] It is easy to understand that, in order to achieve the aforementioned descaling reaction, the cathode plate 1 can be made of stainless steel, titanium-based platinum-plated (Ti / Pt) or titanium-plated ruthenium (RuO2 / Ti) material, and the anode plate 2 is usually made of boron-doped diamond (BDD), mixed metal oxide (MMO) or other materials; the first mounting part 4 and the second mounting part 5 can both be set as U-shaped steel.

[0024] like Figure 3As shown, the cathode plate includes a first cathode plate 101 and a second cathode plate 102. Adjacent first cathode plates 101 and second cathode plates 102 are paired together, and a hollow drainage area exists between the first cathode plates 101 and second cathode plates 102 within the same pair. The anode plate 2 is located between adjacent pairs of first cathode plates 101 and second cathode plates 102 (e.g., between the first cathode plate 101 of the first pair and the second cathode plate 102 of the second pair). That is, at least one pair of first cathode plates 101 and second cathode plates 102 exists between two adjacent anode plates 2. To improve adsorption efficiency, the first cathode plates 101, second cathode plates 102, and anode plates 2 are all arranged perpendicular to the direction of circulating water flow (i.e., the first direction). The electrode plates are arranged alternately, with the sides of the first cathode plate 101, the second cathode plate 102, and the anode plate 2 all facing the direction of circulating water flow. This increases the contact area between the circulating water and the first and second cathode plates 101 and 102 as the circulating water passes through the cathodes and anodes, thus increasing the reaction area and the number of ions that can be adsorbed (due to the increased number of ions under the influence of the electric field), thereby improving the adsorption and descaling efficiency. Specifically, the circulating water to be treated forms scale in the hollow drainage area and is adsorbed onto the first cathode plate 101 and / or the second cathode plate 102, and then detaches from the first cathode plate 101 or the second cathode plate 102 under external vibration. The specific details can be adjusted according to actual needs and are not limited here. Furthermore, the material and structural design of the electro-adsorption module must consider corrosion resistance and conductivity to ensure long-term stable operation. Optimizing the electric field strength and electrode spacing (<30mm) further enhances the adsorption effect and reduces energy consumption. In practical applications, the electrode shape and spacing can be flexibly adjusted according to water quality characteristics and treatment requirements to achieve the best descaling effect.

[0025] Specifically, the hollow drainage area between the first cathode plate 101 and the second cathode plate 102 is connected to a pumping pipe 13, and the other end of the pumping pipe 13 is connected to a sedimentation tank. The circulating water in the hollow drainage area enters the external sedimentation tank through the pumping pipe 13 under external influence (such as electric pumping or external air pressure), and finally circulates through the external sedimentation tank. During the electro-adsorption descaling process, hydroxide ions and hydrogen ions are generated near the electrodes under the action of the electric field. Hydrogen ions form hydrogen gas, thereby inhibiting the adsorption of scale. At the same time, hydroxide ions increase the pH value of the water. At this time, the end of the pumping pipe 13 near the hollow drainage area is set in the upper part of the hollow drainage area, thereby reducing the pH value of the water.

[0026] To ensure that the scale can be effectively removed from the electrode, such as Figure 2-6As shown, a vibrating element 3 can be bolted to the top of the first mounting component 4. In this embodiment, the vibrating element 3 is a vibration motor. The base of the vibration motor is fixed to the fixed part of the electrode (usually the first cathode plate 101 or the second cathode plate 102). An acceleration sensor is installed on the vibration motor for closed-loop amplitude adjustment to avoid excessive vibration leading to electrode fatigue. When it is necessary to separate the scale from the electrode, the vibration motor is started to drive the electrode to vibrate. When the vibration frequency reaches a certain value, the scale is shaken off. To improve separation efficiency, such as... Figure 4-5 As shown, the electrode is provided with several insulating regions 11. The insulating regions 11 and non-insulating regions 12 are alternately distributed along the direction of scale detachment or along the direction of circulating water flow. Therefore, when the electrode vibrates, the scale in the insulating region 11 will detach from the electrode first, and at the same time, it can carry the scale in the non-insulating region 12 to detach together to the external scale tank, which improves the efficiency of the scale falling into the external scale tank as a whole. In particular, the non-insulating region 1211 can be etched and modified with fluorosilane to form a micro-nano-level hydrophobic / hydrophilic patterned surface, which discretizes the nucleation points of the scale and further reduces the adhesion. At the same time, the insulating region 11 is coated with an insulating coating such as PTFE or ceramic coating, with a coating thickness ≥50 μm, to ensure long-term insulation reliability. The bottom of the external scale tank can be laid with a polytetrafluoroethylene plate with a thickness ≥2 mm to ensure long-term insulation stability and reliability.

[0027] Among them, such as Figure 2-5 As shown, the insulating region 11 may be composed of a plurality of insulating through holes 112, which are arranged sequentially along the first direction and / or the second direction, or randomly arranged on the first cathode plate 101 or the second cathode plate 102; it may also be composed of a plurality of grid lines 111 to divide the non-insulating region 12 into a plurality of grids; or it may be composed of a plurality of insulating strips 113, which are parallel to each other; no limitation is made here.

[0028] The first mounting component 4 and the second mounting component 5 are parallel to the first direction. When there are multiple sets of cathode plates and anode plates 2, there are also multiple sets of first mounting components 4 and second mounting components 5, which are arranged sequentially along the direction of circulating water flow, so that the circulating water flows through the gap between the cathode and anode plates, reducing water flow resistance. The first mounting component 4 is set as a U-shaped steel and has a first wiring space 41 for wiring. The first wiring space 41 can hold cables for powering the cathode plate and vibrating component 3. The second mounting component 5 is set as an angle steel and has a second wiring space 51 for holding cables for powering the anode plate 2. It should be noted that when the first mounting component 4 vibrates, it will affect the surrounding environment. To reduce this impact, a buffer component 7 can be set on the mounting base 6. The buffer component 7 is located between the mounting base 6 and the first mounting component 4 and / or the second mounting component 5. The buffer component 7 can be set as a device or equipment with elastic buffering capacity, such as buffer rubber or buffer spring array.
