[0002] Heat exchangers are widely used in various industrial fields to efficiently transfer heat between different media. Their main function is to transfer heat from high-temperature fluids to low-temperature fluids through conduction and convection, achieving efficient energy conversion and utilization. In various processes, the performance of heat exchangers directly affects the system's energy consumption and efficiency; therefore, their reliability, durability, and operating efficiency are all crucial.

[0003] Traditional heat exchange equipment typically consists of various materials and components, mainly including heat transfer surfaces, pipes, shells, support structures, and connectors. These components work together to achieve fluid flow, heat transfer, and temperature control during the heat exchange process. Through appropriate design and material selection, each part ensures that the equipment can operate stably for extended periods under specific conditions.

[0004] Traditional heat exchangers typically use metallic materials such as steel and copper. Under high temperatures, humidity, or chemical media, these materials undergo surface reactions, leading to oxidation or corrosion. Corrosion weakens the equipment's strength and thermal conductivity, affecting heat exchange efficiency and causing leaks or damage, further resulting in system failures and increased maintenance and replacement costs. Therefore, corrosion is a significant factor affecting the long-term stable operation of traditional heat exchangers. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a corrosion prevention device for heat exchange equipment, which aims to improve the problem that corrosion of traditional heat exchange equipment weakens the strength and thermal conductivity of the equipment, affects the heat exchange efficiency, and leads to leakage or damage to the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion prevention device for heat exchange equipment, comprising a body, the outer wall of which is coated with a fluoride coating, a DC power supply on the side wall of the body, a conduit fixedly connected to the output end of the DC power supply, one end of the conduit fixedly connected to the inside of the body, a current controller on the side wall of the body, an electrode monitor on the side wall of the body, a corrosion inhibitor dosing tank fixedly connected to the side wall of the body, a water quality monitor fixedly connected to the side wall of the body, and a transmission component on the top of the corrosion inhibitor dosing tank.

[0007] Furthermore, the transmission component includes multiple connecting pipes and a fixing pipe, with the multiple connecting pipes fixedly connected to the top of the body and the fixing pipe fixedly connected to one end of each connecting pipe.

[0008] Furthermore, both sides of the fixed tube are rotatably connected to connecting shafts, and each connecting shaft is fixedly connected to a rotating plate on its outer wall.

[0009] Furthermore, a second rotating plate is fixedly connected to the lower surface of each of the rotating plates, and a spring is provided on the side wall of the second rotating plate.

[0010] Furthermore, one end of the spring is fixedly connected to the two side walls of the rotating plate, and the other end of the spring is fixedly connected to the outer wall of the fixed tube.

[0011] Furthermore, the top of the corrosion inhibitor dosing box is fixedly connected to multiple fixing tubes, and each fixing tube has a slot inside.

[0012] Furthermore, each of the rotating plates is fixedly connected to two side walls with a limiting plate, which is slidably connected inside the slot.

[0013] Furthermore, an inner tube is fixedly connected to the bottom of the fixed tube, and the inner tube is slidably connected inside the connecting ring.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, current is first provided by DC power supply and transmitted to the inside of the machine body through conduit, thereby realizing electrochemical anti-corrosion treatment. Corrosion inhibitor addition box regularly adds corrosion inhibitor to the inside of the machine body, effectively reducing the corrosive effect of corrosive media on the surface of the equipment, improving the durability of the equipment, ensuring that the equipment is in the best working environment, thereby comprehensively improving the anti-corrosion effect of the equipment and extending its service life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-2 This utility model provides an embodiment of an anti-corrosion device for heat exchange equipment, comprising a body 1, with a fluoride coating 2 on the outer wall of the body 1. The fluoride coating 2 effectively reduces the corrosion of the equipment surface by the external environment and enhances the corrosion resistance of the body 1. A DC power supply 3 is provided on the side wall of the body 1, and a conduit 4 is fixedly connected to the output end of the DC power supply 3. One end of the conduit 4 is fixedly connected to the inside of the body 1, transmitting current to the inside of the body 1 through the conduit 4 to ensure the smooth progress of electrochemical anti-corrosion treatment. A current controller 5 is provided on the side wall of the body 1, which can adjust the current intensity to adapt to different working environments and anti-corrosion requirements, thereby optimizing the electrochemical anti-corrosion effect. An electrode monitor 6 is provided on the side wall of the body 1, which monitors the status of the electrodes in real time to ensure accurate application of current and prevent corrosion. Because electrode damage or excessive wear affects the corrosion prevention effect, a corrosion inhibitor dosing tank 7 is fixedly connected to the side wall of the body 1. The corrosion inhibitor dosing tank 7 periodically adds corrosion inhibitor to the inside of the body 1, thereby reducing the corrosive effect of the corrosive medium and further improving the durability of the equipment. A water quality monitor 8 is fixedly connected to the side wall of the body 1. The water quality monitor 8 monitors the water quality of the heat exchange medium, detects the pH value and the concentration of corrosive substances in the water, and ensures that the equipment operates in the optimal water quality environment, thereby effectively preventing corrosion caused by water quality problems. A transmission component is set on the top of the corrosion inhibitor dosing tank 7. The transmission component ensures the uniform distribution of corrosion inhibitor and maintains the continuity and stability of corrosion control within the system. These components work together to improve the corrosion prevention effect of the heat exchange equipment, extend the service life of the equipment, and ensure that the equipment maintains a good working condition during long-term operation.

[0024] Specifically, the anti-corrosion device protects the outer wall of the machine body 1 with a fluoride coating 2, thereby reducing the corrosive effects of external environmental factors on the equipment. A DC power supply 3 installed on the side wall of the machine body 1 provides current, which is transmitted to the inside of the machine body 1 through a conduit 4 for electrochemical anti-corrosion treatment. A current controller 5 is responsible for adjusting the current intensity to adapt to the needs of different working environments, ensuring that the anti-corrosion process can proceed stably and achieve the expected results. An electrode monitor 6 monitors the status of the electrodes in real time to ensure that the current is applied correctly and to prevent the electrodes from being affected by excessive wear or damage, thus affecting the anti-corrosion effect. A corrosion inhibitor dosing tank 7 periodically adds corrosion inhibitors to the inside of the machine body 1 to reduce the corrosive effect of corrosive media on the surface of the equipment, thereby extending the service life of the equipment and improving its durability. In addition, a water quality monitor 8 is responsible for monitoring the water quality of the heat exchange medium, timely detecting changes in the chemical composition of the water, such as pH value or the concentration of corrosive substances, to ensure that the equipment operates in a suitable working environment, effectively improving the anti-corrosion effect of the equipment, reducing the risk of corrosion, thereby extending the service life of the equipment and maintaining stable operation.

[0025] Reference Figure 3 The transmission component includes multiple connecting pipes 9 and fixed pipes 10. The multiple connecting pipes 9 are fixedly connected to the top of the body 1. The fixed pipes 10 are fixedly connected to one end of each connecting pipe 9. Connecting shafts 11 are rotatably connected to both sides of the fixed pipes 10. A rotating plate 12 is fixedly connected to the outer wall of each connecting shaft 11. A rotating plate 2 13 is fixedly connected to the lower surface of each rotating plate 12. A spring 15 is provided on the side wall of the rotating plate 2 13. One end of the spring 15 is fixedly connected to the side wall of the rotating plate 2 13, and the other end of the spring 15 is fixedly connected to the outer wall of the fixed pipe 10. Multiple fixed pipes 10 are fixedly connected to the top of the corrosion inhibitor dosing box 7. A slot 18 is opened inside each fixed pipe 10. A limiting plate 14 is fixedly connected to the side wall of each rotating plate 2 13. The limiting plate 14 is slidably connected inside the slot 18. An inner pipe 17 is fixedly connected to the bottom of the fixed pipe 10. The inner pipe 17 is slidably connected inside the connecting ring 16.

[0026] Specifically, when cleaning the connecting pipe 9 is required, pressing the rotating plate 12 causes the connecting shaft 11 to rotate, which in turn causes the rotating plate 2 13 to move the limiting plate 14. The limiting plate 14 disengages from the slot 18, releasing the restriction on the inner pipe 17 and the connecting ring 16. In this way, the inner pipe 17 can be smoothly pulled out from inside the connecting ring 16, and the connection between the corrosion inhibitor dosing box 7 and the connecting pipe 9 can be disassembled and reassembled through the action of the spring 15. This makes the disassembly and installation of the connecting pipe 9 more convenient, reduces the time and workload required for maintenance, and improves the maintenance efficiency of the equipment. It also facilitates regular inspection, cleaning and replacement of the connecting pipe 9, ensuring that the heat exchange system can continuously maintain a good working condition and avoiding the impact of pipe blockage or other problems on the normal operation of the equipment.

[0027] Working Principle: The anti-corrosion device first protects the outer wall of the body 1 with a fluoride coating 2, reducing the corrosion caused by the external environment. A DC power supply 3 located on the side wall of the body 1 provides current, which is transmitted to the interior of the body 1 through a conduit 4, thus achieving electrochemical anti-corrosion treatment. A current controller 5 adjusts the current intensity to adapt to different working environments and requirements, ensuring the stability and effectiveness of the anti-corrosion process. An electrode monitor 6 monitors the electrode status in real time, ensuring correct current application and preventing excessive electrode wear or damage. A corrosion inhibitor dosing tank 7 periodically adds corrosion inhibitors to the interior of the body 1, effectively reducing the corrosive effect of the corrosive medium on the equipment surface and improving the equipment's durability. Simultaneously, a water quality monitor 8 monitors the heat exchange medium... High-quality water quality is ensured by timely monitoring of changes in chemical composition, such as pH value or concentration of corrosive substances, to maintain the equipment in an optimal working environment. This comprehensively improves the equipment's corrosion resistance and extends its service life. When cleaning of the connecting pipe 9 is required, pressing the rotating plate 12 will rotate the connecting shaft 11, causing the rotating plate 13 to displace the limiting plate 14 from the slot 18, releasing the restriction on the inner pipe 17 and the connecting ring 16. The inner pipe 17 can then be pulled out from inside the connecting ring 16, and the corrosion inhibitor dosing box 7 and the connecting pipe 9 can be easily disassembled and reassembled via the spring 15. This improves the equipment's maintenance efficiency, facilitates regular inspection, cleaning, and replacement of the connecting pipe 9, and ensures that the heat exchange system always maintains a good working condition.
