Description

Technical Field

[0001] The invention relates to the technical field of electrochemical water treatment, and in particular to an electrochemical circulating water treatment device utilizing automatic brush descaling. Background Art

[0002] Cooling water systems are generally divided into direct cooling water systems and circulating cooling water systems. In direct cooling water systems, water operation costs are high, utilization rates are low, and water resources are seriously wasted. Therefore, direct cooling water systems have been gradually eliminated. In circulating cooling water systems, cooling water is heated up by heat exchange equipment, cooled in cooling towers, and then enters the cooling system for recycling, saving water resources, reducing emissions, and improving cooling water utilization. It is widely used in industrial production. The physical field or electrochemical principle used by the circulating water descaling device can inhibit the formation and deposition of scale from the root, achieving a long-term and stable descaling effect; in terms of sustainability, the device can work online in real time without downtime for processing, ensuring the continuous operation of the water system; in terms of environmental protection, it avoids the damage to the environment and corrosion of equipment by chemical agents; in terms of maintenance costs, due to its relatively advanced working principle, it may only require regular inspections and simple maintenance, reducing manpower and material investment; in terms of the impact on the system, it will not introduce new impurities or change the properties of water, ensuring the safe and reliable operation of the water system, and can easily precipitate calcium and magnesium ions in the water in the form of precipitation, reducing the hardness of the circulating water, and increasing the concentration ratio, achieving the purpose of energy conservation and emission reduction.

[0003] Common water treatment technologies currently on the market include chemical reagents, membrane separation, osmosis, ion exchange, and electrochemical methods. The main drawbacks of these methods are significant corrosion to circulating water treatment equipment and poor removal of bacteria and algae in the circulating water. Furthermore, current methods are generally costly and tend to introduce extra ions into the circulating water, generating contaminated waste solids and impacting the environment.

[0004] Traditional electrochemical water treatment methods often suffer from suboptimal treatment results and low efficiency when faced with complex water quality and high dirt content. In particular, dirt easily accumulates on components such as the cathode plate during the treatment process. If not cleaned promptly, this can seriously affect water treatment results and the normal operation of the equipment.

[0005] In the existing technology, patent number CN201922480785.8, the patent name is a descaling device for an electrochemical reaction chamber. The above scheme achieves the complete removal of the scale layer on the surface of the electrode plate, greatly improving the electrolysis effect and the stability of the flushing process. At the same time, it eliminates the safety hazards caused by scraper breakage and the inefficiency caused by scraper maintenance. It has the advantages of reasonable structure, simple processing and low cost. However, in the above scheme, under the action of the drive mechanism, the brush rod is driven to rotate in the circumferential direction within the channel formed by the adjacent electrode plates and the brush rod itself rotates. The rotational motion may cause the brush to repeatedly rub in certain positions, resulting in local excessive wear of the cathode plate, affecting the service life and performance of the cathode plate. In addition, there may be some areas that are difficult to effectively cover during rotation. When the rotating brush contacts the electrode plate, the contact area between the cylindrical surface and the electrode plate is smaller than the flat contact surface. During rotation, the cleaning effect is better at the center of the electrode plate, but the two sides of the electrode plate edge cannot be effectively cleaned by rotation. Especially in places where the surface of the cathode plate has complex shapes or special structures, it is easy to have cleaning dead corners. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a fully automatic controlled circulating water descaling device, which can effectively solve the difficulty of manually removing the scale layer during the process of reducing the hardness of circulating water, avoid the need to stop the operation of the equipment, thereby greatly reducing the operating costs and labor costs, and greatly improving the efficiency of electrochemical circulating water descaling.

[0007] In order to solve the above problems, the technical solution adopted by the invention is: an electrochemical circulating water treatment device using automatic brush descaling, characterized in that: it includes a box body, a plurality of cathode plates are arranged inside the box body, anode plates are arranged on both sides of the cathode plates, and the anode plates and cathode plates are cooperatively connected with the box body; a driving device for driving up and down reciprocating motion is arranged inside the box body, a telescopic rod is fixedly arranged on the upper end of the driving device, a plate brush frame is arranged on the telescopic rod, a plurality of plate brushes are arranged on the plate brush frame, and the plate brushes are arranged between the cathode plates and are fitted with the cathode plates; a sedimentation tank is provided at the lower end of the box body, the sedimentation tank is integrated with the box body, and a discharge port is provided at the lower end of the sedimentation tank; a water inlet is provided on one side of the box body, and a plurality of water outlets are provided on the side wall of the box body.

[0008] The beneficial effects of this program are:

[0009] 1. By setting up a driving device that drives the plate brush for reciprocating motion up and down to remove scale, compared with the traditional rotary descaling method, it can remove the dirt on the cathode plate more comprehensively and efficiently, reduce the occurrence of cleaning dead corners, and avoid the problem of local excessive wear of the cathode plate, thereby helping to extend the service life of the cathode plate, reduce equipment maintenance and replacement costs, reduce interference with the water body, and make the entire water treatment process more stable and reliable.

[0010] Furthermore, the plate brush frame includes a fixed connector and a connecting rod connection arrangement, and the connecting rod and the fixed connector are detachable structures. When a part of the plate brush frame is damaged or worn, the part can be removed and replaced separately without replacing the entire frame, thereby reducing maintenance costs and time. The combination of the connecting rod and the fixed connector can be flexibly adjusted according to different descaling requirements and the arrangement of the cathode plates to adapt to different working conditions. If some parts are damaged, only specific parts need to be produced and replaced instead of the entire frame, which helps to reduce production costs.

[0011] Furthermore, the plate brush is provided with multiple horizontal through-holes on one side near the plate. These horizontal through-holes evenly distribute the cleaning material, making the cleaning process more comprehensive and efficient. Through these through-holes, the cleaning fluid or material can more evenly contact the plate surface, avoiding localized accumulation or omissions, and improving the quality of cleaning. At the same time, the through-holes also improve the flow properties of the cleaning material, ensuring smooth cleaning and reducing the occurrence of blockage or stagnation. In addition, this design can also increase the interactivity and adaptability between the cathode plate brush and the plate, better responding to different plate conditions and dirt conditions.

[0012] Furthermore, the two ends of the sedimentation tank are tilted toward the center. This tilted design encourages sediment to converge more naturally and quickly toward the center, effectively improving its aggregation efficiency and reducing its dispersion within the tank. Furthermore, the tilted structure helps concentrate sediment in specific areas, facilitating subsequent cleaning and discharge, making the sediment discharge process more efficient and thorough, and reducing the risk of residual sediment. Furthermore, this design reduces dead spots within the sedimentation tank, preventing sediment from accumulating in certain areas for extended periods and becoming difficult to handle.

[0013] Furthermore, the anode plate and cathode plate are provided with a plurality of through-holes, which can significantly improve the permeability and uniformity of water flow, allowing water to flow more smoothly between the plates, promoting full contact and reaction between water and the plates, thereby improving the efficiency and effectiveness of water treatment. The through-holes can also enhance the exchange and transmission of substances, facilitate the movement and treatment of various ions, precipitates, etc. between the plates, and reduce local accumulation and unevenness. In addition, this design can increase the surface area of the plates, further improving the reaction activity and treatment capacity of the plates. Through these through-holes, the uniformity of the electric field distribution between the plates can be better achieved, optimizing the entire electrochemical circulating water treatment process.

[0014] Furthermore, a waterproof sealing groove is provided on the outside of the drive unit, effectively blocking water intrusion and providing reliable waterproof protection for the drive unit. The waterproof sealing groove forms an effective barrier, preventing water from penetrating into key parts of the drive unit, ensuring that the drive unit operates in a relatively dry and safe environment, maintaining its stable and reliable performance. This significantly reduces the risk of drive unit failure due to water ingress, extends the service life of the drive unit, ensures the continuous and stable operation of the entire electrochemical circulating water treatment device, improves the overall reliability and durability of the equipment, and reduces the adverse effects of downtime and maintenance caused by drive unit failure.

[0015] Furthermore, the plate brush is made of an elastic fiber material. This material has excellent elastic deformation capabilities and can better adapt to the different surface shapes of the cathode plate, achieving a tight fit, thereby ensuring more comprehensive and in-depth cleaning and treatment effects. Its elastic properties can also reduce hard contact with the cathode plate, reducing wear and damage to the cathode plate surface, which is beneficial for protecting the integrity and performance of the cathode plate. In addition, the elastic fiber material is generally more flexible and is not easily broken or damaged during use, extending the service life of the cathode plate brush.

[0016] Furthermore, a cathode plate slot and an anode plate slot are provided on the inner side wall of the box body. The cathode plate slot and the anode plate slot are arranged in parallel. The cathode plate and the anode plate are respectively connected to the cathode plate slot and the anode plate slot, making the installation of the plate more stable and reliable, and effectively preventing the plate from moving unnecessarily during operation, ensuring the uniformity and stability of the current distribution, thereby improving the effect and quality of water treatment. The parallel arrangement of the slots ensures that the relative position between the cathode plate and the anode plate is accurate and fixed, which is conducive to forming a stable electric field and enhancing the controllability of the electrochemical treatment. In addition, this matching connection method facilitates the installation and removal of the plate, and when maintenance or replacement of the plate is required, it can be operated more conveniently, reducing manpower and time costs.

[0017] Furthermore, there are four plate brushes, which are arranged in parallel and spaced uniformly. The sum of the spacing between the plate brushes is equal to the height of the cathode plate, making the cathode plate more comprehensively and evenly covered, and enabling effective treatment from multiple positions simultaneously, thereby improving the efficiency and quality of the treatment. The consistent spacing helps maintain the uniformity of current distribution, avoiding local current overshoot or undershoot, thereby ensuring the stability and reliability of the entire treatment process. The sum of the spacing equal to the height of the cathode plate ensures that all areas of the cathode plate can be fully covered, reducing omissions.

[0018] Furthermore, the plate brush is provided with a plurality of reeds, which are arranged in cooperation between the plate brush and the cathode plate. The reeds can provide elastic support and contact force, so that the plate brush and the cathode plate maintain close and flexible contact. Even if the cathode plate undergoes a certain degree of deformation or position change during operation, the reeds can adapt through their own elastic deformation, always ensuring a good contact effect, thereby improving the stability and reliability of the process. The provision of multiple reeds increases the number of contact points, further strengthening the effect of such close contact, which is conducive to the uniform distribution of current and the full conduct of the reaction. This design can also reduce problems such as energy loss and reduced efficiency caused by poor contact. At the same time, the elastic properties of the reeds can also play a certain buffering role, reducing the friction and wear between the plate brush and the cathode plate, and extending the service life of both.

[0023] The following is further described in detail through specific implementation methods:

[0024] The figure marks in the drawings of the specification include: support frame 1, box body 2, anode plate 3, connecting rod 4, fixed connector 5, plate brush frame 6, drive device 7, cathode plate 8, plate brush 9, sedimentation tank 10, discharge port 11, water inlet 12, water outlet 13, waterproof sealing groove 14, and reed 15.

[0025] Example 1

[0026] As the instruction manual Figure 1 -Attached Figure 4 As shown, an electrochemical circulating water treatment device using automatic brush descaling includes a box body 2, in which a plurality of cathode plates 8 and anode plates 3 are arranged in parallel, and the anode plates 3 are arranged on both sides of the cathode plate 8, and the cathode plates 8 and the anode plates 3 are both connected with the card slots provided on the box body 2, and the cathode plates 8 and the anode plates 3 are both porous. The porous structure can significantly improve the permeability and uniformity of water flow, so that water can flow more smoothly between the plates, promotes full contact and reaction between water and the plates, thereby improving the efficiency and effect of water treatment. The through holes can also enhance the exchange and transmission of substances, which is beneficial to the movement and treatment of various ions, precipitates, etc. between the plates, reducing local accumulation and unevenness.

[0027] The plate brush frame 6 is connected by the connecting rod 4 through the fixed connector 5, so that the plate brush frame 6 can be adjusted according to the situation. The connecting rod 4 is set on one side of the plate, and there are four plate brushes 9 set on the connecting rod 4 on one side of the plate. The plate brushes 9 are set in parallel, and the spacing between the plate brushes 9 is consistent. The sum of the spacing of the plate brushes 8 is equal to the height of the cathode plate 8, so that the coverage of the cathode plate 8 is more comprehensive and uniform, and can be effectively processed from multiple positions at the same time, thereby improving the efficiency and quality of the processing. The consistent spacing helps to maintain the uniformity of the current distribution and avoid the situation where the local current is too large or too small, thereby ensuring the stability and reliability of the entire processing process. The sum of the spacing is not less than the height of the cathode plate 8 to ensure that all areas of the cathode plate 8 can be fully covered and omissions can be reduced.

[0028] A plurality of springs 15 are provided on the plate brush 9 and on one side surface close to the cathode plate 8 and are fixedly connected to the plate brush 9. The springs 15 are arranged between the plate brush and the cathode plate 8. The springs 15 can provide elastic support and contact force, so that the plate brush 9 and the cathode plate 8 maintain close and flexible contact. Even if the cathode plate 8 undergoes a certain degree of deformation or position change during operation, the springs 15 can adapt through their own elastic deformation, thereby always ensuring a good contact effect.

[0029] The driving device 7 is provided inside the box body 2 for reciprocating driving up and down. The driving device 7 includes but is not limited to an electric push rod, and can also be a hydraulic rod and a crank-connecting rod mechanism. Waterproof sealing grooves are provided around the driving device 7, so that the driving device 7 has better waterproof performance. A telescopic rod is provided at the upper end of the driving device 7, and a plate brush frame 6 is provided on the telescopic rod. The driving device 7 drives the telescopic rod and the plate brush frame 6 to slide up and down. The plate brush frame 6 includes a connecting rod 4 and a fixed connecting member 5. Vertically arranged connecting rods 4 are provided on both sides of the cathode plate 8, and a plate brush 9 is provided on the connecting rod 4. The plate brush 9 is fitted between the cathode plate 8, and horizontal through holes are provided on the left and right sides of the plate brush 9, which penetrate the plate brush 9. These horizontal through holes can evenly distribute the cleaning material, making the cleaning process more comprehensive and efficient. Through these through holes, the cleaning fluid or material can more evenly contact the surface of the plate, avoiding local accumulation or omission.

[0030] The plate brush 9 is made of elastic fiber material. The elastic fiber material has good elastic deformation ability and can better adapt to the different surface shapes of the cathode plate 8 to achieve a tight fit, thereby ensuring a more comprehensive and in-depth cleaning and treatment effect.

[0031] A sedimentation tank 10 with inclined ends is provided at the lower end of the box body 2. The sedimentation tank 10 is connected to the box body 2 as a whole. A discharge port 11 is provided at the lower end of the sedimentation tank 10. The sediment scraped off the cathode plate 8 is discharged through the discharge port 11. A support frame 1 is provided on one side of the sedimentation tank 10. The support frame 1 is welded to the box body 2 so that the box body 2 can be better and more stably supported.

[0032] A water inlet 12 is provided on one side of the box body 2, and a water outlet 13 is provided on the front and rear sides of the box body 2. Water enters through one side of the box body 2, and water is discharged from the box body 2 on both sides. Water is discharged through the front and rear sides of the box body 2. First, multi-directional outflow of water can be achieved, and the path and area of water outlet are increased, so that the treated water can be discharged from the box body 2 more quickly and evenly, avoiding the local water accumulation or poor drainage problems that may be caused by a single water outlet 13. This multi-directional water outlet design is conducive to improving the water flow and treatment efficiency of the entire system, and enhancing the working performance of the device. At the same time, water outlet on the front and rear sides also helps to achieve a more uniform hydraulic distribution and reduce water flow dead corners and stagnation areas.

[0033] Example 2

[0034] As the instruction manual Figure 1 -Attached Figure 4As shown, an electrochemical circulating water treatment device using automatic brush descaling includes a box body 2, which is made of high-strength stainless steel to ensure that it can operate stably for a long time in a harsh working environment. The multiple cathode plates 8 and anode plates 3 inside the box body 2 are accurately and firmly installed through the cathode plate 8 slots and the anode plate 3 slots that are connected to the box body 2.

[0035] During operation, circulating water enters from the water inlet 12 on one side of the box body 2. Since multiple through holes are provided on the anode plate 3 and the cathode plate 8, the water can flow evenly between the plates, thereby improving the treatment effect.

[0036] After the treatment process continues for a period of time, scale begins to appear on the cathode plate 8. At this time, the driving device 7 is started, driving the telescopic rod to move up and down, and the plate brush frame 6 on the telescopic rod moves accordingly. The four plate brushes 9 on the plate brush frame 6 are arranged in parallel and at the same spacing. The sum of their spacings is not less than the height of the cathode plate 8, so that the cathode plate 8 can be fully brushed.

[0037] The plate brush 9 is made of elastic fiber material, and is provided with multiple horizontal through holes on the side close to the plate, and multiple reeds 15 are also provided between the plate brush and the cathode plate 8. These designs enable the plate brush 9 to effectively remove scale during the brushing process without causing damage to the cathode plate 8. At the same time, the presence of the reed 15 increases the strength and effect of the brushing.

[0038] The scale removed by the brush falls to the sedimentation tank 10 at the lower end of the box 2 under the action of gravity. The two ends of the sedimentation tank 10 are inclined toward the middle, which is conducive to the centralized sedimentation of the scale. When the sediment accumulates to a certain level, it can be discharged through the discharge port 11 at the lower end of the sedimentation tank 10.

[0039] During the entire processing process, a waterproof sealing groove 14 is provided on the outer side of the driving device 7, which effectively prevents water from entering the interior of the driving device 7 and ensures its normal operation.

[0040] Descaling principle: The water in the circulating water tank is passed into the electrochemical descaling device, and OH is generated during the electrochemical reaction on the cathode plate. - , OH produced by the cathode plate reaction - Ions break the balance between alkalinity and hardness in the solution near the cathode plate, and HCO3 in the solution - Converted to CO3 2- , while the Ca in water 2+ Mg 2+ The scale-forming ions migrate to the cathode area under the action of electrostatic attraction, and form CaCO3 and Mg(OH)2 precipitates respectively. -It will be oxidized into free chlorine components such as chlorine gas, hypochlorous acid, and hypochlorite, diffuse to the negatively charged bacterial surface, and penetrate into the bacteria through the bacterial cell wall, causing oxidation to destroy the bacterial enzyme system and kill the bacteria. In the electrochemical reaction, some short-lived intermediates, namely ozone, hydroxyl free radicals, hydrogen peroxide and oxygen free radicals, are generated on the electrode surface through the electrochemical reaction of ions and oxygen dissolved in water. These strongly oxidizing substances can oxidize multiple components in microbial cells, causing irreversible changes in the microorganisms and their death.

[0047] The above is only an embodiment of the invention, and the common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several variations and improvements can be made without departing from the structure of the invention, and these should also be regarded as the scope of protection of the invention.
