Description

Technical Field

[0001] This utility model relates to the field of acetylene gas purification technology and is an electrochemical circulating water treatment device. Background Technology

[0002] With the rapid development of industrial production, circulating water systems play a vital role in processes such as cooling and heating. However, during operation, circulating water systems often face problems such as scaling and bacterial growth. These problems not only affect the system's heat exchange efficiency but may also lead to equipment corrosion and pipe blockage, and in severe cases, even cause production accidents.

[0003] To address these issues, electrochemical processes are widely used in circulating water treatment. This process utilizes the working anode and cathode to adsorb calcium and magnesium ions in the circulating water onto the cathode surface, effectively removing these ions and reducing the risk of scaling in the circulating water system. Simultaneously, the oxidants generated at the anode, such as Cl2, H2O2, HClO3, OH-, O3, and Cl, possess strong oxidizing properties and can sterilize the circulating water system, significantly reducing the corrosive damage caused by bacteria and microbial slime.

[0004] However, in practical applications, electrochemical processes for treating circulating water also face some technical challenges. Firstly, during electrochemical treatment, calcium and magnesium ions adsorb onto the surface of the cathode rod, forming scale. This scale not only affects the electrochemical treatment effect but can also clog the cathode rod surface, thus impacting the normal operation of the entire circulating water system.

[0005] To maintain the effectiveness of electrochemical treatment, the cathode rod surface needs to be descaled regularly. However, existing equipment cannot simultaneously remove scale after descaling, leading to scale accumulation inside the equipment. This not only increases maintenance costs but may also cause equipment malfunctions and downtime risks. Each descaling cycle requires shutdown for scale removal, which wastes time and manpower and may impact production schedules and efficiency.

[0006] Therefore, in response to the problems existing in current technologies, there is an urgent need for a new electrochemical treatment technology and equipment for circulating water that can effectively solve the problem of scale accumulation on the cathode rod surface, simultaneously remove scale, and reduce equipment maintenance costs and downtime risks. Such a technology and equipment can not only improve the operating efficiency and stability of the circulating water system, but also extend the service life of the equipment, reduce production costs, and provide strong support for the sustainable development of industrial production. Summary of the Invention

[0007] This utility model provides an electrochemical circulating water treatment device that overcomes the shortcomings of the prior art and can effectively solve the problem that existing electrochemical water treatment devices are prone to cathode scaling and difficult to discharge after descaling.

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0024] Example 1: As shown in the attached document Figure 1 , 2As shown in Figures 3 and 4, the electrochemical circulating water treatment equipment includes a treatment tank 1, a left fixed column 2, a right fixed column 3, an anode rod 4, a cathode rod 5, and a lifting and cleaning device. The left fixed column 2 and right fixed column 3 are spaced apart inside the treatment tank 1. An anode rod 4 and a cathode rod 5 are respectively mounted on the upper side of the left fixed column 2 and right fixed column 3. An inlet pipe 6, an outlet pipe 7, and a drain pipe 8, which communicate with the interior of the treatment tank 1, are respectively located on the upper, lower outer, and lower sides. The lifting and cleaning device includes a cleaning ring 9, a fixing ring 10, an installation ring 11, a collection cylinder 12, and a lifting assembly. A cleaning ring 9 is sequentially fitted from top to bottom on the outer side of the right fixed column 3. The assembly includes a cleaning ring 9, a fixing ring 10, and an installation ring 11. The upper side of the fixing ring 10 is fixedly mounted with the cleaning ring 9, and the lower side of the fixing ring 10 is detachably fixedly mounted with the installation ring 11. The outer side of the installation ring 11 is fixedly mounted with a collection cylinder 12 located on the outer side of the lower part of the cathode rod 5. The collection cylinder 12 is a mesh cylinder with an opening facing upward. The upper side of the treatment tank 1, which is located above the cathode rod 5, is provided with an installation hole. The upper side of the treatment tank 1 is equipped with a lifting device whose lower end is fixedly mounted together with the outer side of the fixing ring 10. The lifting device can move the cleaning ring 9 up and down along the outer surface of the cathode rod 5 and can lift the collection cylinder 12 from the installation hole to the top of the treatment tank 1. During use, by setting up a lifting component, it is easy to pull the fixing ring 10 up and down, thereby moving the cleaning ring 9 upward along the outer surface of the cathode rod 5, scraping off the scale on the outer surface of the cathode rod 5 and letting it fall into the collection cylinder 12; by setting up the collection cylinder 12, the scale scraped off the outer surface of the cathode rod 5 is collected, and after the collection cylinder 12 is pulled out of the treatment tank 1 through the installation hole, it is easy to clean the scale collected inside.

[0025] The above-mentioned electrochemical circulating water treatment equipment can be further optimized and / or improved according to actual needs:

[0026] Example 2: As shown in the attached document Figure 1 , 2 As shown in Figures 3 and 4, the upper part of the cleaning ring 9 is a frustum shape with a smaller upper part and a larger lower part. A fixing ring 10 is fixedly installed on the outer side of the lower end of the cleaning ring 9 by means of a threaded connection. During use, by setting a conical surface on the upper part of the cleaning ring 9, it is easy for the cleaning ring 9 to move upward along the outer surface of the cathode rod 5, scraping off the scale on the outer surface of the cathode rod 5 and letting it fall into the collection cylinder 12.

[0027] Example 3: As shown in the attached document Figure 1 , 2As shown in Figures 3 and 4, the inner side of the middle of the fixing ring 10 is provided with a mounting ring groove 13, and the lower side of the fixing ring 10 is provided with at least two mounting notches 14 that can communicate with the mounting ring groove 13 at intervals along the circumference. The upper outer side of the mounting ring 11 corresponding to each mounting notch 14 is provided with a fixing ear 15 located in the mounting ring groove 13. In use, this setting facilitates the quick and detachable fixing of the fixing ring 10 and the mounting ring 11 together. When fixing the two, after inserting the fixing ear 15 into the mounting ring groove 13 through the mounting notch 14, the mounting ring 11 is rotated to make the mounting notch 14 and the fixing ear 15 misaligned. When separating the two, the mounting ring 11 is rotated to make the mounting notch 14 and the fixing ear 15 correspond in position, so that the fixing ear 15 can be removed from the mounting notch 14.

[0028] Example 4: As shown in the appendix Figure 1 , 2 As shown in Figures 3 and 4, the lifting device includes a support plate 16, a support rod 17, a connecting block 18, a fixing rod 19, and an electric push rod 20. Two support rods 17 are provided at intervals on the upper side of the treatment tank 1 corresponding to the mounting hole position. The support plate 16 is fixedly installed between the upper ends of the two support rods 17. The upper center of the support plate 16 is provided with a lifting hole that runs vertically through it. An electric push rod 20 is provided on the upper side of the support plate 16. A piston rod 21 located in the lifting hole and able to extend downward is provided on the lower side of the flashlight push rod. A connecting block 18 is installed on the outer side of the lower end of the piston rod 21. At least two fixing rods 19, whose upper ends are installed together with the connecting block 18 at corresponding positions, are fixedly installed on the outer side of the fixing ring 10 along the circumference. During use, the support rod 17 supports the electric push rod 20 through the support plate 16, thereby enabling the piston rod 21 to extend or retract from the electric push rod 20; the electric push rod 20 retracts the piston rod 21, thereby causing the connecting block 18 and the fixing rod 19 to move the fixing ring 10 upward. The cleaning ring 9 provided on the upper side of the fixing ring 10 moves upward along the outer surface of the cathode rod 5, scraping off the scale on the outer surface of the cathode rod 5 and letting it fall into the collection cylinder 12. The mounting ring 11 provided on the lower side of the fixing ring 10 lifts the collection cylinder 12 out of the treatment tank 1 through the mounting hole.

[0029] Example 5: As shown in the attached document Figure 1 , 2 As shown in Figures 3 and 4, the bottom of the collection cylinder 12 is arc-shaped. During use, the arc-shaped bottom design of the collection cylinder 12 makes it easier for the scraped scale to slide down to the lowest point of the collection cylinder 12 under the action of gravity, thus facilitating the collection of scale and subsequent cleaning, and reducing corners and dead zones where scale accumulates.

[0030] Example 6: As attached Figure 1 , 2As shown in Figures 3 and 4, the tank also includes support legs 22. At least three support legs 22 are provided at circumferential intervals along the lower outer side of the treatment tank 1. During use, the support legs 22 provide stable support points for the treatment tank 1, ensuring that the treatment tank 1 remains level and does not shake during the circulating water treatment process. This is crucial for maintaining the uniform distribution of liquid inside the tank and avoiding operational problems caused by tilting.

[0031] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and the best implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.

[0032] The specific usage process of this utility model embodiment is as follows: (1) During water treatment, circulating water enters the treatment tank 1 supported by the support leg 22 through the liquid inlet pipe 6. At this time, the anode rod 4 and cathode rod 5 supported by the left fixed column 2 and the right fixed column 3 respectively perform electrochemical treatment on the circulating water. Then the treated circulating water is discharged through the liquid outlet pipe 7; (2) During descaling, the support rod 17 supports the electric push rod 20 through the support plate 16. The electric push rod 20 retracts the piston rod 21, thereby the connecting block 18 and the fixed rod 19 drive the fixed ring 10 to move upward. The cleaning ring 9 set on the upper side of the fixed ring 10 moves upward along the outer surface of the cathode rod 5, scraping off the scale on the outer surface of the cathode rod 5 and letting it fall into the tank. Inside the collection cylinder 12, the mounting ring 11 set on the lower side of the fixing ring 10 will pull the collection cylinder 12 out of the treatment tank 1 through the mounting hole. Then rotate the mounting ring 11 so that the fixing ear 15 separates the mounting ring 11 from the fixing ring 10 through the mounting notch 14. That is, the collection cylinder 12 is removed and the scale removed from the collection cylinder 12 is poured out to avoid the scale removed from accumulating in the treatment tank 1, thereby reducing the frequency of shutdown and sewage discharge and improving water treatment efficiency; (3) After long-term use, when too much other dirt accumulates in the treatment tank 1, stop the inflow and outflow of circulating water, open the sewage valve set on the sewage pipe 8, and backflush with clean water from the liquid outlet pipe 7 to flush the dirt out of the collection cylinder 12 through the sewage pipe 8.
