[0001] The present invention relates to the field of electro-adsorption descaling technology, and more specifically, to an electro-adsorption descaling system and its control method. Background Technology

[0002] In industrial and municipal circulating water treatment processes, scaling problems caused by excessively high water hardness (such as calcium and magnesium ions) have long plagued technicians in related fields. Traditional descaling methods mainly include chemical softening, ion exchange, and membrane separation.

[0003] Traditional descaling methods result in incomplete descaling reactions and low descaling efficiency, requiring repeated descaling of circulating water, which increases descaling costs. Summary of the Invention

[0005] According to one embodiment of the present invention, an electro-adsorption descaling system is provided, comprising: At least one set of electro-adsorption descaling modules, wherein the electro-adsorption descaling modules adsorb and descale the circulating water when energized; A vibrating element drives the electro-adsorption descaling module to vibrate, so that the scale generated during the adsorption descaling process is detached from the electro-adsorption descaling module.

[0006] In an exemplary embodiment, the electro-adsorption descaling module includes at least a pair of anodes and cathodes, the cathode having multiple insulating regions, and the insulating regions and non-insulating regions being arranged alternately along the direction of circulating water flow or the direction of scale shedding.

[0007] In an exemplary embodiment, the electro-adsorption descaling module includes at least a pair of anodes and cathodes, the cathodes including a first cathode body and a second cathode body, and an adsorption space is provided between the first cathode body and the second cathode body.

[0008] In one exemplary embodiment, the distance between the cathode and the anode is less than a preset value.

[0009] In one exemplary embodiment, it further includes: The reaction tank includes a first chamber for holding circulating water; The scale-water separation box includes a second chamber for collecting scale from the electro-adsorption descaling module; The electro-adsorption descaling system adsorbs and removes scale from the circulating water in the reaction tank, and the scale-water separation tank collects the scale generated during the adsorption and descaling process.

[0010] In an exemplary embodiment, at least one set of water flow guide plates are fixedly provided on the side wall of the first housing. The water flow guide plates collect the water flowing into the first housing to a target area, which includes the area of ​​the water flow guide plates near the upstream side of the water flow.

[0011] In an exemplary embodiment, a vertical filter element and a horizontal filter element are fixedly disposed inside the first housing, and the bottom of the vertical filter element is fixedly connected to the horizontal filter element; the horizontal filter element and the vertical filter element cooperate with the side wall of the first housing to form a water outlet area, and the water outlet of the first housing is connected to the water outlet area.

[0012] In an exemplary embodiment, the scale-water separation tank is provided with a scale-inhibiting and water-permeable component, which filters the circulating water after adsorption and descaling.

When the adsorption and descaling reaches the first time, a vibration command is sent to the vibrating component, causing the vibrating component to drive the electro-adsorption descaling module to vibrate. The scale adsorbed on the electro-adsorption descaling module falls off under the vibration and falls into the scale-water separation tank. When the degree of scale removal on the electro-adsorption descaling module reaches a preset condition or the load-bearing capacity of the scale-water separation box reaches a preset target, the electro-adsorption descaling module is instructed to stop vibrating, and the scale-water separation box is instructed to move to transport the scale.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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).

[0023] Example 1 This application provides an electro-adsorption descaling system, such as Figure 1-15 As shown, the system includes a reaction tank 1 for holding the circulating water to be treated, an electro-adsorption descaling module for adsorbing and descaling the circulating water to be treated, a scale-water separation tank 3 for collecting the scale generated during the electro-adsorption process, and a support frame 4 for installing the reaction tank 1. The bottom of the support frame 4 is bolted to the installation ground, and a buffer is provided between the support frame 4 and the reaction tank 1. The buffer can be an elastic sponge, spring, etc., which is not limited here. There is a receiving space under the support frame 4 to accommodate the scale-water separation tank 3. The electro-adsorption descaling module includes a vibrating element 23 and at least one set of cathodes 21 and anodes 22, which are fixedly connected to the reaction tank 1 through an installation structure. The cathode 21 can be made of stainless steel, titanium-based platinum-plated (Ti / Pt) or titanium-plated ruthenium (RuO2 / Ti) material, and the anode 22 is usually made of boron-doped diamond (BDD), mixed metal oxide (MMO), etc. The cathode 21 and anode 22 of the electro-adsorption descaling module extend into the reaction tank 1 and come into contact with the circulating water in the reaction tank 1.

[0024] When circulating water needs treatment, power is supplied to cathode 21 and anode 22, creating an electric field of 10-15 V / cm within the reaction chamber. Under the influence of this electric field, cations in the circulating water (such as calcium and magnesium ions) migrate directionally and adsorb onto the electrode surface (usually the cathode), forming solid scale (typically composed of calcium carbonate and other solids, with a density of approximately 2.7 g / cm³). 3 The vibration component is dynamically controlled by a turbidity sensor preset in the reaction chamber 1. For example, when the thickness of the scale on the electrode surface is ≥3mm, the detachment program is triggered. At this time, the cathode 21 is driven to vibrate by the vibration component 23, so that the scale is detached from the electrode and falls into the reaction chamber 1, and then falls into the scale-water separation tank 3 along the reaction chamber 1.

[0025] To improve adsorption efficiency, such as Figure 2As shown, both cathode 21 and anode 22 are plate-shaped, and they are arranged alternately in a direction perpendicular to the flow direction of the circulating water (i.e., the first direction), meaning the sides of cathode 21 and anode 22 face the flow direction of the circulating water (i.e., the second direction). This increases the contact area between the circulating water and cathode 21 and anode 22 as the water passes through them, thus increasing the reaction area and allowing more ions to be adsorbed (due to the increased ions under the influence of the electric field), thereby improving the descaling efficiency. Of course, cathode 21 and anode 22 can also be arranged in a mesh shape, etc., depending on actual needs; no specific limitations are made here. Furthermore, the materials and structural design of the electro-adsorption descaling module must also consider corrosion resistance and conductivity to ensure long-term stable operation. By optimizing the electric field strength and electrode spacing, the adsorption effect is further improved while reducing energy consumption. In practical applications, the electrode shape and configuration can be flexibly adjusted according to water quality characteristics and treatment requirements to achieve the best descaling effect. In particular, the electrode current density is greater than 50 A / sqm, preferably 150 A / sqm. This is because when the current density increases, the pH at the cathode-water interface is relatively high, and the alkaline interface is thicker, which leads to more bicarbonate ions (HCO3-). - ) and hydroxide ions (OH) - The reaction produces carbonate ions (CO3-). 2- The concentration of calcium ions (Ca) increases. Simultaneously, the scale inhibitor's chelating ability at the alkaline interface is weaker, leading to a greater concentration of calcium ions (Ca). 2+ ) is released and mixes with CO3 2- The interaction between the current density and the scale buildup results in a looser scale deposit. Therefore, the higher the current density, the looser the scale. At the same time, the higher the current density, the faster the reaction rate and the more calcium carbonate precipitates. Thus, with the same distance between the anode and cathode, the higher the current density, the faster the scale buildup. For example, the scale buildup rate at 150 amps per square meter is faster than at 80 amps per square meter.

[0026] To ensure that the scale can be effectively removed from the electrode, such as Figure 2-3As shown, the electro-adsorption device also includes a vibrating element 23, and the distance between the anode 22 and the cathode 21 is less than 30mm. In this embodiment, the vibrating element is a vibration motor, and the output shaft of the vibration motor is fixedly connected to the fixed part of the electrode (usually the cathode 21). 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. Generally, the device is powered on for 24 hours. The system continuously performs adsorption and descaling. Once the scale buildup is complete, the power is cut off and the descaling program is started, or the program is initiated when the voltage is increased by 10%-20% from its original value. Compared to existing technologies, the inclusion of a vibrating element 23 allows for continuous adsorption and descaling without requiring system shutdown, significantly improving descaling efficiency. The vibrating element 23 should not vibrate for too long; typically, the vibration time should be less than 2 minutes. Simultaneously, the cathode 21 should vibrate less than 1.5 mm towards the anode 22 during vibration to minimize damage to the equipment. Furthermore, it is necessary to ensure… The high vibration frequency and small vibration amplitude, combined with the action of the aforementioned insulating region 211 and non-insulating region 212, allow scale to be quickly detached from the electrodes, with only one vibration per cycle. It should be noted that since the vibrating element 23 can automatically start for vibration descaling, scale collection can be completed without stopping the equipment, greatly reducing downtime for descaling and improving descaling efficiency. Furthermore, in existing technologies, the distance between the anode 22 and the cathode 21 is approximately 200-300 mm, or even 500 mm, to facilitate electrode cleaning after shutdown. Descaling; however, this application, due to the inclusion of a vibrating element 23, enables automatic descaling without requiring shutdown for cleaning, thus increasing the number of anodes 22 and cathodes 21, thereby increasing adsorption and descaling efficiency; furthermore, the greater the distance between cathodes 21 and anodes 22, the more electrical energy is required to generate a sufficiently strong electric field to achieve electron migration and scale formation; but because the distance between the anode and cathode in this application is close and the electrolyte resistance is low, only 2~5V voltage needs to be supplied to the electrodes under the same current, significantly reducing energy consumption, and the shorter electron migration distance and faster electron migration speed allow the cathode to quickly capture Ca. 2+ Mg 2+ (Short ion migration distance, no loss), electrochemical reaction efficiency is close to 100%, so under the same current, the scaling speed is 3 to 5 times that of the existing technology; in addition, due to the close distance between the anode and cathode, the scale is more likely to be present in the magnet of the electrolytic cell, so less scale will be adsorbed on the cathode 21. At the same time, because the scaling speed is fast and the scale generated is mostly "fine powder" (crystallization is fast and the particles are small under strong electric field), most of it does not adhere to the cathode 21 and directly sinks to the bottom, so the amount of scale accumulated at the bottom of the reaction tank 1 is much greater than that of the existing technology, which facilitates the collection and treatment of scale.

[0027] Among them, to improve separation efficiency, such as Figure 2-5 As shown, the electrode has several insulating regions 211. The insulating regions 211 and non-insulating regions 212 are alternately distributed along the direction of scale detachment or along the direction of circulating water flow. When the electrode vibrates, the presence of the insulating regions 211 and non-insulating regions 212 makes the scale structure on the cathode 21 very loose and easy to fall off. The scale in the insulating region 211 will detach from the electrode first, and at the same time, it can carry the scale in the non-insulating region 212 to fall off to the external scale tank, improving the efficiency of the scale falling into the external scale tank as a whole. In particular, the non-insulating region 212 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 211 is coated with an insulating coating such as PTFE or ceramic coating with a coating thickness of ≥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 of ≥2 mm to ensure long-term insulation stability and reliability.

[0028] Among them, such as Figure 2-5 As shown, the insulating region 211 may be composed of a plurality of insulating through holes 2112, which are arranged sequentially along the first direction and / or the second direction, or randomly arranged on the cathode 21; it may also be composed of a plurality of grid lines 2111 to divide the non-insulating region 212 into a plurality of grids; it may also be composed of a plurality of insulating strips 2113, which are parallel to each other; no limitation is made here.

[0029] To facilitate the installation of cathode 21 and anode 22, such as Figure 1-5As shown, the reaction tank 1 is fixedly equipped with several mounting brackets. The mounting brackets are parallel to the arrangement direction of the cathode 21 and the anode 22 and are located above the water flow of the circulating water. When there are multiple sets of electro-adsorption descaling modules, there are also multiple sets of mounting brackets, which are arranged sequentially along the direction of water flow, so that the circulating water flows through the gap between the anode and cathode, reducing water flow resistance. The mounting brackets include a cathode support 24 and an anode support 25. The cathode support 24 is set as a U-shaped steel, and the anode support 25 is set as an angle steel. The cathode support 24 is used to fix the cathode 21 and the vibrating element 23. The vibrating element 23 is fixed to the cathode support 24 with bolts. The cathode support 24 is provided with a wiring space for wiring. The wiring space can be used to place cables for powering the cathode 21, anode 22, and vibrating element 23. The anode support 25 is used to fix the anode 22. The vibrating element 23 drives the cathode 21 to vibrate through the cathode support 24. The cathode support 24 and the anode support 25 are fixedly connected to external equipment via a mounting base 26. The cathode 21 is fixed below the cathode support 24 and perpendicular to the cathode support 24, and the anode 22 is fixed below the anode support 25 and perpendicular to the anode support 25. When the cathode support 24 vibrates, it will affect the surrounding environment. To reduce this impact, a buffer 27 can be provided on the mounting base 26. The buffer 27 is located between the mounting base 26 and the cathode support 24 and / or the anode support 25. The buffer 27 can be a device or equipment with elastic buffering capacity, such as buffer rubber or a buffer spring array.

[0030] Specifically, since the mounting bracket is fixedly connected to the reaction chamber 1, when the cathode support 24 vibrates, it will cause the reaction chamber 1 to vibrate as well. In this case, to avoid damage to the support frame 4 (e.g., ...) during vibration... Figure 1 and Figure 6 To mitigate the impact (as shown), a buffer is provided between the reaction chamber 1 and the support frame 4. The buffer can be a device or equipment with elastic buffering capabilities, such as buffer rubber or a buffer spring array. In particular, the cathode support 24 has an embedded PVC cable tray (40×20mm) to effectively protect the cables from mechanical damage and corrosion by circulating water. It should be noted that the cathode support 24 has a reserved T-slot, compatible with sliding rail equipment supports, supporting quick assembly and disassembly of the electro-adsorption descaling equipment. A Φ50mm cable passage hole is opened in the middle of the cathode support 24 to facilitate the insertion of new cables. At the same time, the cable tray of the cathode support 24 is filled with flame-retardant silicone pads (UL94 V-0 grade) to absorb the vibration energy of the equipment. Rubber shock-absorbing blocks can also be added at the joints to reduce the risk of resonance.

[0031] like Figure 1 and Figure 6-8As shown, the reaction chamber 1 includes a first chamber body. The two ends of the first chamber body are respectively provided with an inlet 11 and an outlet 12. Both the inlet 11 and outlet 12 are equipped with solenoid valves for opening and closing. The first chamber body has an inlet area 111 and an outlet area 121. The inlet 11 is located in the inlet area 111. A vertical filter element 151 and a horizontal filter element 152 are fixedly installed inside the reaction chamber 1. The bottom of the vertical filter element 151 is fixedly connected to the horizontal filter element 152 to form an L-shaped filter element. Simultaneously, the horizontal filter element 152 cooperates with the vertical filter element 151 in conjunction with the first chamber body. The side wall forms a water outlet area 121, and the water outlet 12 of the first chamber is connected to the water outlet area 121. The vertical filter element 151 and the horizontal filter element 152 can be set as filter cloth, filter screen, filter sponge, activated carbon, or other filter materials to further filter the fine particulate matter and colloidal suspended matter generated during the electro-adsorption descaling process, so that the turbidity of the effluent is ≤5 NTU. In particular, since the filter element is L-shaped, it forms an upper and lower channel, effectively filtering the circulating water from multiple angles. The vertical filter element 151 can be arranged in multiple rows, with a thickness of 50-200 mm. It should be noted that... Figure 1 and Figure 6 Two different support frames 4 are provided as examples only, and are not intended to limit the structure of the support frame 4.

[0032] To ensure that the circulating water is fully adsorbed and descaled in the first tank, such as Figure 9 As shown, at least one set of water flow guide plates 313 are symmetrically arranged on the inner sidewall of the first tank along the length of the first tank. The water flow guide plates 313 protrude inward in a direction away from the inner sidewall of the first tank, perpendicular to the direction of circulation water movement. Specifically, three sets of ABS water flow guide plates 313 are welded to the inner sidewall of the first tank. When the circulation water passes through the water flow guide plates 313, the water flow guide plates 313 collide with the water flow, thereby forcing the water flow to form a backflow in the "target area" near the upstream side of the water flow guide plates 313, realizing the convergence of water flow and improving the adsorption reaction efficiency; at the same time, by The water flow guide plates 313 are symmetrically arranged so that the water flow is collected by the water flow guide plates 313 to the aforementioned "target area"; wherein, the "target area", the electrode and the water flow guide plates 313 are at the same horizontal level, that is, the water flow guide plates 313 are located in the upper half of the first housing; at the same time, in order to prevent the circulating water from forming scale on the water flow guide plates 313, the water flow guide plates 313 can be made of insulating parts, or an insulating coating can be sprayed on the surface of the water flow guide plates 313. For example, a 0.2 mm thick PTFE insulating coating can be sprayed on the surface of the water flow guide plates 313, so that the surface resistance is >10. 12 Ω, completely eliminating the risk of scaling on the water flow guide plate 313; the preferred cathode support 24 and anode support 25 can be set above the aforementioned "target area" of circulating water return, so that the adsorption electrode can be located in the "target area" and fully adsorb and react with the circulating water.

[0033] When the scale detaches from the electrode and falls into the first chamber, in order to collect it in the first chamber, such as... Figure 10 As shown, the bottom 10 of the first box is funnel-shaped, and at the same time, as Figure 10 As shown, the first housing can be provided with multiple funnel-shaped bottoms 10. The outer walls of the funnel-shaped bottoms 10 can be reinforced and supported by inclined reinforcing ribs 14 (usually X-shaped 304 stainless steel). The funnel-shaped bottoms 10 are connected by connecting holes (diameter Φ50mm). The connecting holes are usually located in the upper half of the funnel-shaped bottoms 10. Circulating water enters the different funnel-shaped bottoms 10 sequentially through the connecting holes under the propulsion of the water flow. The funnel-shaped bottoms 10 can be divided into a buffer zone 181 and a collection zone 182. The buffer zone 181 is located in the collection zone. Above and to the side of collection zone 182, scale detaches from the adsorption electrode and passes sequentially through buffer zone 181 and collection zone 182, accumulating in collection zone 182. The angle between buffer zone 181 and collection zone 182 is greater than or equal to 120°, preferably greater than 150°; for example, the angle between buffer zone 181 and collection zone 182 is 155°, the inner wall is polished to Ra≤0.8μm, and the slope of collection zone 182 is >60° to ensure that the scale slides off naturally. Collection zone 182 may also have a 5mm thick EPDM rubber gasket with a surface resistance <10 Ω·cm. 6 Ω, to eliminate electrostatic adsorption.

[0034] To ensure that the scale ultimately falls into the scale-water separation tank 3, each funnel-shaped first tank has a scale discharge hole 16 at its bottom 10. A scale discharge valve 17 is installed outside the scale discharge hole 16. When the scale discharge valve 17 is open, the scale falls through the scale discharge hole 16 into the external scale collection device. Otherwise, the scale discharge valve 17 is closed. The scale discharge hole 16 is usually located above the external scale collection device. Since the first tank is funnel-shaped, after the scale falls off the electro-adsorption descaling device 2, it slides along the side wall of the funnel through the buffer zone 181 and the collection zone 182 to the scale discharge hole 16 and is finally discharged, thus treating the scale. In particular, the scale discharge hole 16 is equipped with a pneumatic butterfly valve (diameter DN80, opening and closing time ≤2s), which is linked with the RFID positioning system of the external scale collection device to achieve automatic docking and discharge.

[0035] Furthermore, to prevent scale from accumulating on the sidewalls of the bottom 10 of the funnel-shaped first housing due to static electricity, a portion of the bottom 10 of the first housing can be made of insulating material (e.g., a rubber pad or insulating coating), or insulating material can be provided on its inner wall to reduce static electricity generation. For example, an insulating coating can be applied to the aforementioned buffer zone 181, collection area 182, and surrounding inner walls. In particular, a descaling drain 18 is also provided on one side of the first housing. When scale needs to be drained, it can be drained through the descaling drain 18 (e.g., a rubber pad or insulating coating). Figure 7As shown, a portion of the circulating water at the bottom of the first tank is discharged first to reduce the amount of circulating water that falls into the scale-water separation tank later. For example, the descaling drain 18 can be located at a low position on the side wall of the first tank, and the residual circulating water can be discharged preferentially by an external screw pump (the flow rate can be adjusted to 5m³ / h) to reduce discharge disturbance. In particular, a filter section can be set at the descaling drain 18, so that when the circulating water is discharged through the descaling drain 18, the circulating water enters the circulation pool through the filter section and returns to the upstream of the system. Then, the scale discharge hole 16 is opened by the scale discharge valve 17, and a vibration command is sent to the vibrating element 23, so that the vibrating element 23 drives the electrode to vibrate. The scale adsorbed on the electrode falls off under the action of vibration and falls into the scale-water separation tank 3 through the reaction tank 1. At this time, some circulating water will fall into the scale-water separation tank 3 along with the scale.

[0036] like Figure 11 Figure 12 As shown, the scale-water separation tank 3 includes a second tank 31, which adopts an integrated box-shaped structure, consisting of a bottom plate, front and rear end plates, left and right side plates, and a removable top cover. Specifically, the side plates and the bottom plate are continuously welded and additionally sealed with adhesive to ensure no leakage under full load; all welds undergo a three-step process of pickling, passivation, and electropolishing. The exterior of the second tank 31 is coated with a double-layer epoxy zinc primer and an aliphatic polyurethane topcoat, with a total coating thickness ≥260 μm. The second tank 31 is typically made of a rigid material to extend its service life. The rigid material can be a metal, such as stainless steel, iron, tungsten steel, or aluminum alloy, or a new material, such as carbon fiber or graphene, or even a thickened plastic, as long as it has sufficient strength and can withstand a certain impact; no specific limitations are imposed here. For example, the second tank 31 is made of 2mm-4mm thick 304 stainless steel plate, integrally bent and welded, because circulating water often contains chloride ions (Cl...). -These ions are highly corrosive to ordinary carbon steel, while 304 stainless steel, rich in chromium (Cr) and nickel (Ni), can form a dense and stable chromium-rich oxide film (passivation film) on the surface, effectively resisting pitting and crevice corrosion of chloride ions. It is especially suitable for handling neutral or weakly alkaline circulating water environments. In particular, under harsh conditions with extremely high chloride ion concentrations or large fluctuations in water pH, it can be upgraded to 316L stainless steel (which has additional molybdenum added to its composition) with better corrosion resistance to balance chloride ion corrosion resistance and high strength requirements. When the scale has strong acid and alkali corrosiveness, a 1-4 mm ECTFE fluoroplastic coating can be used as an inner lining. For lightweight scenarios (such as rooftop units), T700 carbon fiber prepreg can be hot-pressed and then coated with a polyurethane wear-resistant layer. When it is necessary to meet the requirements of single use or when cost is extremely sensitive, a 30% glass fiber reinforced PP injection molded shell is selected, with an internal stainless steel keel to enhance impact resistance. However, regardless of the material, all materials must pass a 1 m drop test and a 3 No plastic deformation occurred during the concentrated load test.

[0037] Because the scale carries some circulating water with it when it detaches from the electrode, it gradually accumulates in the second tank 31 after falling into it. To remove this circulating water and reduce secondary pollution to the surrounding environment, such as... Figures 11-12As shown, one end of the second housing 31 is provided with a drain outlet 33, which can be configured as a tubular outlet. A filter element 35 and a drain valve 36 are provided at the drain outlet 33. The filter element 35 can be threaded to the end of the drain outlet 33 located inside the second housing 31, or bolted, or fixed via a flange or other means. The drain valve 36 is used to control the opening or closing of the drain outlet 33. Simultaneously, a scale-inhibiting and water-permeable component 34 is provided inside the second housing 31. The scale-inhibiting and water-permeable component 34, together with the second housing 31, forms a settling zone 311 and a drainage zone 312. Both the drain outlet 33 and the filter element 35... Located at the bottom of the drainage zone 312, the drain valve 36 is located outside the second tank 31. When the vibrating element 23 is working, a mixture of flake, block, or powdery scale containing a large amount of water falls into the settling zone 311 inside the tank. Due to gravity, the denser solid scale begins to settle naturally, forming a preliminary solid-liquid stratification. Subsequently, as the liquid level in the second tank 31 rises, the relatively clear scale water on the upper layer begins to flow towards the drainage zone 312 under the action of static pressure difference. During this process, the scale water first needs to pass through the scale-blocking and water-permeable element 34, which can effectively intercept most of the suspended fine scale particles, making... The water remains in settling zone 311, achieving initial filtration and separation of circulating water or wastewater. Subsequently, filter element 35 performs secondary filtration of the circulating water to remove even smaller suspended solids, ensuring that the discharged water meets reuse or discharge standards and preventing any solid particles from clogging the drain valve and subsequent pipelines. This achieves secondary filtration of the circulating water while also preventing debris in the circulating water from clogging the drain outlet. To facilitate effective discharge of the circulating water, a support structure (such as a U-shaped steel bar) can be installed at the bottom of settling zone 311, ensuring that the bottom of settling zone 311 is higher than the bottom of drainage zone 312. The height difference is set at a level that allows circulating water to flow to the drainage area 312. The height difference ranges from 5 to 15 cm, with 8 cm being preferred. This is because a height difference of less than 5 cm results in insufficient static pressure head to drive the water flow, which may lead to slow drainage, especially when the surface of the scale-inhibiting permeable element is partially blocked. If the height difference is greater than 15 cm, it will unnecessarily increase the total height and volume of the tank, increasing manufacturing costs and equipment space requirements. When draining, the drain valve 36 is opened, and the circulating water in the drainage area 312 is filtered by the filter element 35 and enters the drain outlet 33, from which it is discharged.

[0038] To improve the filtration efficiency of the scale-inhibiting and permeable element 34, such as Figure 11-12As shown, the scale-inhibiting and permeable component includes a support plate 341 and a permeable cloth 342 fixed on the support plate 341. The support plate 341 is made of a rigid material to provide support and withstand the impact force of circulating water. For example, it can be a perforated plate (porosity must be greater than 50% to reduce water flow resistance), a metal mesh, or a welded steel mesh. Among these, the perforated plate is a preferred choice because its flat surface facilitates the laying and fixing of the permeable cloth. The support plate 341 can be fixed by opening an installation groove in the side wall of the second tank 31, or by installing a permeable cloth on the second tank 31. The support plate 341 is installed by fixing the side wall with bolts or welding the mounting bracket, and then installing the support plate 341 through the mounting groove or mounting bracket. The material of the permeable cloth 342 can be 80-150 mesh (i.e. 0.106mm-0.180mm) polyester filter cloth, and its pore size cannot be greater than 0.18mm, otherwise some scale will pass through the scale-blocking and water-permeable parts. Moreover, most of the scale particles that are valuable for recovery have a diameter much larger than 0.18mm. Choosing this pore size can effectively intercept the vast majority of scale while maintaining low water flow resistance and avoiding excessive clogging.

[0039] To facilitate the movement of the second housing 31, a drive assembly can be installed at the bottom of the second housing 31, such as... Figure 11 and Figure 12 As shown, the drive assembly includes guide wheels 325 located at the bottom of the second housing, a drive motor 323, and transmission components such as a chain (not shown) and drive gears (not shown). There are two pairs of guide wheels 325, each pair mounted on both ends of a mounting shaft. The drive gears are mounted on the mounting shaft and driven by the chain. The drive motor 323 drives at least one pair of guide wheels 325 to rotate, and then drives the other pair of guide wheels 325 to rotate via the chain, thereby realizing the movement of the second housing 31. The drive motor 323 is controlled by an external controller; that is, the drive motor 323 drives the guide wheels 325 to rotate only after receiving a drive command from the external controller. The drive command can be transmitted via a wireless network or bus, etc., which is not limited here. To accommodate as much scale as possible, the guide wheels 325 can be made of metal and equipped with guide rails 324, along which the guide wheels 325 slide; or as... Figure 3As shown, the drive assembly is configured as a transmission motor and a transmission shaft 321. Multiple transmission shafts 321 are provided, their length direction perpendicular to the movement direction of the second housing 31, and the transmission shafts 321 are arranged sequentially along the movement direction of the second housing 31. Specifically, a transmission motor can be provided at one end of each transmission shaft 321, or a transmission motor can be provided at one end of one or more transmission shafts 321, and transmission can be achieved through a chain or other transmission assembly. The transmission motor drives the transmission shaft 321 to rotate, causing the transmission shaft 321 to provide a force to the second housing 31, thereby driving the second housing 31 to move. The drive assembly can also be in other forms; no limitation is made here. It is easy to understand that regardless of how the drive assembly is configured, the drive motor 323 / transmission motor and the aforementioned vibration motor are all uniformly controlled by an external controller to achieve precise control of the electro-adsorption descaling and vibration descaling processes.

[0040] Example 2 The difference from Example 1 is that, as Figure 13 As shown, the cathode plate body includes a first cathode plate 213 and a second cathode plate 214. Adjacent first cathode plates 213 and second cathode plates 214 are paired together, and there is a hollow drainage area between the first cathode plates 213 and second cathode plates 214 in the same group. The anode 22 is located between adjacent groups of first cathode plates 213 and second cathode plates 214 (for example, between the first cathode plate 213 in the first group and the second cathode plate 214 in the second group). That is, there is at least one pair of first cathode plates 213 and second cathode plates 214 between two adjacent anodes 22. In order to improve the adsorption efficiency, the first cathode plate 213, the second cathode plate 214, and the anode 22 are all perpendicular to the direction of circulating water flow. (i.e., the first direction) are arranged alternately, that is, the sides of the first cathode plate 213, the second cathode plate 214, and the anode 22 all face the direction of circulating water flow. In this way, when the circulating water passes through the cathode 21 and the anode 22, the contact area between the circulating water and the first cathode plate 213 and the second cathode plate 214 is large, the reaction area of ​​the circulating water is increased, thereby increasing the number of ions that can be adsorbed in the circulating water (because more ions are affected by the electric field), and improving the adsorption and descaling efficiency. Specifically, the circulating water to be treated forms scale in the hollow drainage area and is adsorbed on the first cathode plate 213 and / or the second cathode plate 214, and falls off from the first cathode plate 213 or the second cathode plate 214 under the action of external vibration.

[0041] Specifically, the hollow drainage area between the first cathode plate 213 and the second cathode plate 214 is connected to a pumping pipe 215, and the other end of the pumping pipe 215 is connected to a sedimentation tank. The circulating water in the hollow drainage area enters the external sedimentation tank through the pumping pipe 215 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 215 near the hollow drainage area is set in the upper part of the hollow drainage area, thereby reducing the pH value of the water.

[0042] Example 3 The difference from Example 1 is that, as Figure 14 As shown, a sedimentation baffle 153 is provided at the outlet area 121 to isolate it from the circulating water. The sedimentation baffle 153, together with the side plate of the first tank, forms the outlet area 121. The outlet 12 is located at the bottom of the outlet area 121, and a 20μm stainless steel filter element 35 is used to ensure that the turbidity of the outlet water is ≤5NTU. The top of the sedimentation baffle 153 is lower than the top of the side plate of the first tank, so that the height of the outlet area 121 is lower than the maximum depth of the first tank. The top of the outlet area 121 is provided with a rectangular overflow port (the width of which is 60% of the width of the first tank) for the circulating water to enter. When the height of the circulating water in the first tank exceeds the height of the outlet area 121, the circulating water enters the outlet area 121 from the rectangular overflow port. Since there is a certain height difference between the height of the circulating water and the bottom of the outlet area 121, When the circulating water falls into the bottom of the outlet zone 121, it collides with the bottom of the outlet zone 121, resulting in the loss of some kinetic energy and a reduction in flow velocity, which can be reduced to below 0.1 m / s at most, promoting secondary sedimentation of micron-sized particles. At the same time, since the width of the rectangular overflow port is 60% of the width of the first tank, rather than the full width design, the water flow will not rush in rapidly over a large area. This controls the initial inflow velocity of the circulating water into the outlet zone 121 to a low range (if the overflow port is too wide, the amount of water entering per unit time will be too large, which will easily lead to an increase in flow velocity). After secondary sedimentation, when the circulating water reaches a certain height in the outlet zone 121, it is discharged from the outlet 12, realizing secondary sedimentation of the circulating water in the outlet zone 121, further improving the descaling efficiency.

[0043] Example 4 The difference from Example 1 is that, as Figure 15As shown, the scale-inhibiting and water-permeable component 34 includes a scale-inhibiting plate 343 and a water-permeable cloth 342. The scale-inhibiting plate 343 has a scale-water separation hole 344 and a second scale-inhibiting hole 345. The scale-water separation hole 344 is located in the upper half of the scale-inhibiting plate 343, and the second scale-inhibiting hole 345 is located in the lower half of the scale-inhibiting plate 343. The diameter of the second scale-inhibiting hole 345 is smaller than the diameter of the scale-water separation hole 344.

[0044] When circulating water or wastewater flows through the scale inhibitor plate 343, the resistance to water flow is much greater than that of the scale-water separation holes 344 in the upper part due to the smaller diameter of the second scale inhibitor hole 345. This causes most of the water flow to tend to pass through the upper part, while the lower layer of water flow slows down and increases in pressure due to the obstruction of the small diameter holes. At this time, some of the water flow is forced to turn upward, causing the lower layer of circulating water or wastewater to form a backflow and collide and shear with the upper layer of circulating water or wastewater, forming a local backflow and vortex zone in front of the scale inhibitor plate 343. This turbulent zone is like a "miniature reactor". The fine scale particles that were originally carried by the water flow and stably suspended become chaotic in this area, and the probability of collision with each other is greatly increased. This collision helps to break the particles. The hydration film on the surface promotes the aggregation of particles into larger particles (i.e., hydraulic flocculation). Once larger particles are formed, their settling velocity increases dramatically (the settling velocity is proportional to the square of the particle diameter). These larger particles are more likely to overcome the influence of the upflow, thus causing the particles that were originally carried to the upper layer to settle to the lower layer of the water flow. Even if some particles do not settle completely, when they reach the scale inhibitor plate with the water flow, they will be intercepted and filtered by the smaller second scale inhibitor pores 345 due to their increased size, thereby achieving sufficient filtration of scale water and improving scale water separation efficiency.

[0045] Example 5 This application also provides a control method for an electro-adsorption descaling system, applied to the aforementioned electro-adsorption descaling system, comprising the following steps: Step S1: Upon receiving the start command, the external controller first opens the inlet 11 and simultaneously closes the outlet 12, allowing the circulating water to be treated to enter the first tank. Then, the control power supply supplies power to the electrodes of the electro-adsorption descaling module, causing the electrodes to generate an electric field, thereby adsorbing and descaling the circulating water in the reaction tank 1 and forming scale on the electrodes. The current is greater than 50A per square hour, and the voltage is the standard adjustable voltage (220V). Step S2: When the adsorption and descaling reaches the preset conditions (e.g., duration greater than or equal to 24 hours (i.e., the first time), or the electrode is completely covered by scale, the scale thickness reaches a certain value, or the voltage is detected to increase by 10%-20% from the original state), first close the inlet 11 to stop the water intake; then instruct the descaling drain 18 to open, so that the circulating water to be treated is discharged from the descaling drain 18 until the water level in the reaction tank is lower than the descaling drain 18; then open the drain hole 16 through the drain valve 17 and send a vibration command to the vibrator 23, so that the vibrator 23 drives the electrode to vibrate, and the scale adsorbed on the electrode falls off under the action of vibration and falls into the scale-water separation tank 3 through the reaction tank 1. At this time, some circulating water will fall into the scale-water separation tank 3 along with the scale. In step S3, when it is determined that the degree of scale removal on the electrode reaches a preset condition (e.g., the scale on the electrode is basically completely removed as determined by the camera), or when the load of the scale-water separation tank 3 reaches a preset target (e.g., the load weight reaches the target weight), the vibrator 23 is instructed to stop vibrating, and then the descaling drain outlet 18 is instructed to be opened to discharge some circulating water; then the outlet 12 is opened, and the scale discharge valve 17 is instructed to open the scale discharge hole 16 to allow the scale to fall into the scale-water separation tank 3 through the scale discharge hole 16; when the scale-water separation tank 3 is full, a drive instruction is sent to the drive component of the scale-water separation tank 3 to control the movement of the scale-water separation tank 3, thereby transporting the scale. In step S4, when the scale-water separation tank 3 moves to its destination, the drain valve 36 is instructed to open the drain outlet 33. Then, the circulating water falls from the settling zone 311 into the drain zone 312. At the same time, it undergoes secondary filtration through the scale-inhibiting and water-permeable element, and then undergoes tertiary filtration through the filter element 35 to achieve multi-level filtration. Finally, it is discharged through the drain outlet 33.

[0046] Through the aforementioned devices and control methods, it is possible to achieve highly efficient descaling of circulating water while simultaneously realizing fully automated operation of scale handling and circulating water treatment, reducing manual labor costs and further improving descaling accuracy and efficiency.

[0047] Example 6 To achieve precise control of the adsorption and descaling process, the method differs from Example 5 in that it further includes: Step S51: Obtain multi-source data such as water quality data, cathode-anode current / voltage data, and vibration frequency of vibrating element 23 inside the first tank; Step S52: Integrate the multi-source data into a time series matrix P: In the formula P 1,1 P represents the calcium ion concentration in the circulating water. 1,2 The pH value of the circulating water, P 1,3 P is the conductivity of the circulating water. 1,4 P is the voltage across the electrode.1,5 P is the current in the electrode. 1,6 P is the impedance of the electrode. 1, The vibration frequency of the vibrating component is given. It should be noted that multi-source data can also be other types of data. This is only used as an example and does not limit the actual content of multi-source data.

[0048] Step S53: Generate a control strategy based on the time series matrix P.

[0049] Specifically, the initial strategy is first determined based on a pre-set database. For example, if the calcium ion concentration is > 200 mg / L, the electric field strength is increased to 4 V / cm; if the pH is > 9, the anodic chlorine evolution reaction is initiated (requiring the presence of Cl). - (Water quality), if the impedance rise rate > threshold, high-frequency vibration (30~50 Hz) is triggered. Impedance spectrum is analyzed using FFT to match the optimal vibration frequency, and so on. Subsequently, the initial strategy is logically modified, for example, based on pH and conductivity, using the following formula: In the formula, K 1,2 As a weight of pH value, This is the actual conductivity. K is the reference conductivity. 1,3 The conductivity is used as the weight; it is then corrected based on the rate of increase in impedance and frequency using the following formula: In the formula, f is the target vibration frequency. As the reference vibration frequency, This is the sensitivity coefficient. If necessary, energy consumption and other factors can also be included in the calculation. This is not limited here, and so on.
