Description

Technical Field

[0001] This utility model relates to the field of industrial circulating water treatment technology, specifically to an electromagnetic scale treatment device for closed-loop cooling towers based on insulated installation. Background Technology

[0002] Closed-circuit cooling towers, as key equipment in industrial cooling systems, are widely used in industries such as power, chemical, and metallurgy. They achieve efficient heat exchange through circulating water. However, during long-term operation, calcium and magnesium ions in the circulating water tend to deposit on the heat exchange tube walls to form scale, which not only reduces heat transfer efficiency but also increases energy consumption and may even cause pipe blockage. Traditional scale treatment methods mainly rely on chemical dosing, which has obvious short-term effects but has problems such as chemical residues and secondary pollution, and does not conform to the current trend of green and environmentally friendly development.

[0003] Currently, some electromagnetic descaling devices on the market are attempting to replace chemical methods, but they have significant drawbacks in the application of closed cooling towers: First, since the outer shell of the cooling tower is mostly made of metal, the electromagnetic field is easily shielded, resulting in a significant reduction in the descaling effect; second, if the electromagnetic equipment is directly installed on the metal tower body, it may cause leakage risk due to poor insulation, affecting operational safety.

[0004] Based on this, an electromagnetic scale treatment device for closed cooling towers with insulated installation is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, the electromagnetic scale treatment device for a closed cooling tower based on insulated installation includes a cooling tower 1. A support assembly is provided on the outside of the cooling tower 1. An inlet 6 and an outlet 7 are respectively provided on both sides of the lower end of the cooling tower 1. A ceramic tube 8 is provided at one end of both the inlet 6 and the outlet 7. A cleaning component is provided on one side of the support assembly.

[0027] The cleaning assembly includes a generator housing 12, a connecting rod 11 fixedly connected to one side of the generator housing 12, an electromagnetic field generator 15 disposed inside the generator housing 12, the output end of the electromagnetic field generator 15 being wrapped around the outside of an adjacent ceramic tube 8, and an insulating layer 16 being disposed between the output end of the electromagnetic field generator 15 and the adjacent ceramic tube 8.

[0028] A sensor bracket 17 is provided on the other side of the bracket assembly. A temperature sensor and a flow rate sensor are provided on the lower surface of the sensor bracket 17 and are installed inside the adjacent ceramic tube 8.

[0029] In this embodiment, the electromagnetic field generator 15 generates an alternating electromagnetic field through a high-frequency oscillation circuit, which acts on the circulating water through the insulation layer 16 and the ceramic tube 8. At the same time, the insulation effect is improved by means of hoisting, which polarizes the water molecules and changes the crystal morphology of calcium and magnesium ions. The temperature sensor and the flow rate sensor monitor the operating parameters inside the ceramic tube 8 in real time, and the detection position is fixed by the sensor bracket 17.

[0030] In one embodiment, such as Figure 4 As shown, a thermally conductive layer 13 is filled between the generator housing 12 and the electromagnetic field generator 15. The thermally conductive layer 13 is made of thermally conductive silicone. The thermally conductive layer 13, which is made of thermally conductive silicone, tightly fills the gap between the electromagnetic field generator 15 and the generator housing 12, controlling the device operating temperature below 65°C. The thermal conductivity is ≥1.5W / m·K, and it also has electrical insulation properties.

[0031] In one embodiment, such as Figure 4 As shown, the insulating layer 16 is made of insulating rubber. The 3mm thick insulating rubber layer 16 is disposed between the output end of the electromagnetic field generator 15 and the ceramic tube 8. Its dielectric strength is ≥18kV / mm, which ensures 1500V safety isolation while allowing high-frequency electromagnetic fields to pass through.

[0032] In one embodiment, such as Figure 3 As shown, inlet pipe 4 and outlet pipe 5 are respectively provided on both sides of inlet 6 and outlet 7, and are all fixedly connected by ceramic pipe 8. Flange 9 is fixedly connected to the adjacent end of inlet 6, outlet 7, inlet pipe 4 and outlet pipe 5 and ceramic pipe 8, and they are connected to each other by insulating bolt 10. Flange 9 is connected to inlet pipe 4 and outlet pipe 5 through ceramic pipe 8. The insulating bolt 10 is made of PEEK material and maintains a seal under a working pressure of 1.6MPa. The entire pipeline system achieves complete potential isolation.

[0033] In one embodiment, such as Figure 1 As shown, the insulating bolt 10 is made of polytetrafluoroethylene, which improves the insulation effect.

[0034] In one embodiment, such as Figure 2 As shown, the support assembly includes a fixed frame 2, which is disposed on the outside of the cooling tower 1. Several support legs 3 are fixedly connected to the outside of the fixed frame 2. The fixed frame 2 adopts a double-layer insulation structure, with the outer layer being ceramic and the inner layer being a rubber buffer pad. The outer ceramic layer of the fixed frame 2 is 5mm thick and provides the main insulation. The inner rubber buffer pad is 3mm thick and absorbs the vibration of the cooling tower 1. The overall structure makes the insulation resistance between the device and the metal tower body >100MΩ.

[0035] In one embodiment, such as Figure 4 As shown, a controller 14 is fixedly connected to the outside of the generator housing 12. The controller 14 is an industrial-grade PLC and is connected to the electromagnetic field generator 15 through an RS485 interface. It can store 10 preset working modes and has an IP54 protection level.

[0036] In one embodiment, such as Figure 4 As shown, the controller 14 is electrically connected to the electromagnetic field generator 15, the temperature sensor, and the flow rate sensor, respectively. The controller 14 receives signals from the temperature sensor and the flow rate sensor in real time and adjusts the power in real time.

[0037] The above embodiments disclose an electromagnetic scale treatment device for closed-loop cooling towers based on insulated installation. A high-frequency alternating electromagnetic field is generated by an electromagnetic field generator 15. This electromagnetic field acts on the circulating water flow through a composite insulation structure of an insulating rubber layer 16 and a ceramic tube 8, effectively changing the crystallization morphology of calcium and magnesium ions in the water and preventing the formation of hard scale. Temperature and flow rate sensors monitor the operating parameters inside the pipes in real time and feed the data back to the controller 14. The controller 14 dynamically adjusts the electromagnetic field parameters based on the monitoring data to achieve intelligent scale removal control. A thermally conductive silicone layer 13 ensures effective heat dissipation of the electromagnetic field generator 15. A double-insulated mounting bracket 2, together with PEEK insulating bolts 10, achieves potential isolation throughout the system. The PTFE inlet pipe 4 and the ceramic tube 8 together form a low-loss electromagnetic transmission channel. The modular design of the flange connection facilitates installation and maintenance. The entire system achieves safe and reliable insulation protection and temperature control while ensuring efficient scale removal performance.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
