Description

Technical Field

[0001] This utility model relates to the technical field of industrial cooling circulation treatment equipment, specifically an electromagnetic excitation device for an industrial cooling circulating water purification host. Background Technology

[0002] In the operation of industrial cooling circulating water systems, scaling and algae growth on the inner walls of pipes have long been key technical challenges plaguing the industry. Scale is mainly formed by the precipitation of calcium and magnesium ions dissolved in the water as insoluble salts such as calcium carbonate and calcium sulfate, which adhere to the pipe surface under conditions of temperature changes and pH fluctuations. Algae growth is due to the abundance of nutrients in the circulating water system and the suitable environmental conditions such as light and temperature for algae growth and reproduction. These problems not only significantly increase the fluid resistance of the pipes, leading to a substantial increase in the energy consumption of the circulating water pump, but also form a heat insulation layer on the surface of the heat exchanger, reducing heat exchange efficiency by 30%-50%. This results in decreased equipment operating efficiency, a surge in energy costs, and in severe cases, even equipment failure or shutdown accidents.

[0003] Currently, the industry widely adopts metal catalyst technology to solve the above problems. This technology is based on electrochemical principles. By installing a metal catalyst device inside the circulating water system pipeline, the metal material undergoes an electrochemical reaction in the aqueous solution, releasing free electrons, changing the electrostatic potential of the fluid, and causing polarization. This polarization effect effectively inhibits the combination of positive and negative ions in the water to form sparingly soluble salt crystals, while simultaneously destroying the crystal structure of existing scale, promoting its gradual dissolution and removal, thereby achieving the purpose of scale prevention and removal.

[0004] Some existing technologies employ a straight-through pipe design for electromagnetic excitation devices. When circulating water passes through this pipe, the electromagnetic device inside disrupts the scale crystals formed in the cooling water. However, this straight-through pipe design has limitations. To ensure the electromagnetic device effectively disrupts the scale crystals as the cooling water passes through, it must be sufficiently long. This results in an excessively long overall electromagnetic excitation device, and even the entire purification unit, increasing the difficulty of equipment installation and space allocation. Utility Model Content

[0005] The purpose of this utility model is to provide an electromagnetic excitation device for an industrial cooling circulating water purification host, which aims to solve the problem of the long electromagnetic excitation device in the above-mentioned technical problems, reduce the horizontal length of the entire purification host, and reduce the difficulty of actual installation and layout.

[0006] The technical solution adopted in this utility model is as follows:

[0008] The treatment tank is used to implement purification treatment of circulating water;

[0009] The processing tank is equipped with a water channel, which is arranged in a meandering manner along the length and height of the processing tank.

[0010] The inlet pipe and outlet pipe are respectively connected to both ends of the water circuit;

[0011] The waterway includes horizontal sections and curved sections. Multiple sets of horizontal sections are arranged vertically at intervals. The curved sections are used to connect the pipe ends of adjacent horizontal sections.

[0012] The electromagnetic excitation lines are concentrically positioned at the center of the horizontal section.

[0013] This utility model also has the following technical features:

[0014] In one embodiment of the present invention, the electromagnetic excitation pipeline includes a coil tube and an electrode tube, the electrode tube is disposed at the center of the coil tube, and the outer wall of the electrode tube is combined with the inner wall of the horizontal section.

[0015] In one embodiment of this utility model, multiple sets of water channels are arranged at intervals along the width direction of the processing box. The horizontal ends of the multiple sets of water channels are fixed together by a fixing plate, and two sets of fixing plates are provided.

[0016] In one embodiment of this utility model, radial connecting frames are provided at both ends of the electrode tube, and the electrode tube is installed inside the coil tube through the radial connecting frames;

[0017] An extension tube is provided on the curved section, one end of the electrode tube extends into the horizontal section and out of the end of the extension tube, and one end of the electrode tube is fixed on the fixing plate.

[0018] In one embodiment of this utility model, the inlets and outlets of the multiple sets of water channels are respectively provided with a first connecting pipe and a second connecting pipe, and the first connecting pipe and the second connecting pipe are vertically downward.

[0019] In one embodiment of the present invention, the processing box is provided with a first sealed chamber and a second sealed chamber at both ends, the first connecting pipe is connected to the first sealed chamber, and the second connecting pipe is connected to the second sealed chamber.

[0020] In one embodiment of this utility model, the processing box is further provided with an inlet pipe and an outlet pipe, the inlet pipe being connected to the first sealed chamber and the outlet pipe being connected to the second sealed chamber;

[0021] A first valve and a second valve are respectively installed on the inlet pipe and the outlet pipe. The first valve is used to close and open the inlet pipe, and the second valve is used to close and open the outlet pipe.

[0022] The other ends of the inlet pipe and the outlet pipe are respectively connected to the main water pipe. A third valve is provided on the main water pipe, and the third valve is located in the pipe body between the inlet pipe and the outlet pipe and the main water pipe.

[0023] In one embodiment of this utility model, the main water pipe is arranged horizontally, and the inlet pipe and the outlet pipe are arranged vertically.

[0024] In one embodiment of this utility model, the inlet pipe and the outlet pipe are arranged along the length of the main water pipe.

[0025] In one embodiment of this utility model, the height of the water inlet of the water channel is lower than the height of the water outlet.

[0026] Compared with existing technologies, the beneficial effects of this utility model are reflected in the following aspects: In terms of equipment space optimization, a meandering water channel structure is adopted, with multiple horizontal sections spaced vertically and connected by curved sections, changing the linear flow channel design of traditional straight pipes. This design can significantly extend the flow path of cooling water within the limited space of the treatment tank, eliminating the need to increase the equipment length to ensure sufficient contact between water flow and electromagnetic interaction, effectively shortening the length of the entire purification unit, reducing the space requirements for equipment installation, and improving the flexibility of site layout.

[0027] To enhance the electromagnetic excitation effect, the electromagnetic excitation pipes are concentrically positioned at the center of the horizontal section, ensuring the uniformity and stability of the electromagnetic field distribution within the horizontal section. As cooling water flows through the meandering waterway, the water in each horizontal section is efficiently stimulated by the electromagnetic excitation pipes. Especially when the water changes direction through bends, the water is disturbed, further enhancing the interaction between the scale crystals and the electromagnetic field, increasing the ability to disrupt the scale crystal structure, and strengthening the scale prevention and removal effects.

[0028] Meanwhile, the meandering water path design extends the residence time of cooling water within the equipment, allowing for a more thorough interaction between the water and the electromagnetic excitation device. Compared to traditional straight-through pipes, this structure allows the cooling water to undergo electromagnetic treatment for a longer period within the same equipment length. This ensures the effectiveness of the electromagnetic effect while avoiding the drawbacks of excessive equipment length, achieving an organic combination of high-efficiency treatment and compact structure. This contributes to improving the overall purification efficiency and operational stability of industrial cooling circulating water systems. Attached Figure Description

[0042] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0043] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0044] It should be noted that some existing electromagnetic excitation devices employ a straight-through pipe design. When circulating water passes through the straight-through pipe, the electromagnetic equipment inside the pipe can disrupt the scale crystals formed in the cooling water. However, this straight-through pipe design has certain limitations. Because the electromagnetic device must be long enough to effectively destroy the scale crystals in the water when the cooling water passes through the straight pipe, this directly leads to an excessively long length of the entire electromagnetic excitation device and even the entire purification unit, which increases the difficulty of equipment installation and space layout. To address this, this utility model proposes an electromagnetic excitation device for an industrial cooling circulating water purification unit, comprising: a treatment tank 10 for purifying the circulating water; a water passage 11 inside the treatment tank 10, the water passage 11 being arranged meanderingly along the length and height of the treatment tank 10; an inlet pipe 20 and an outlet pipe 30 respectively connected to both ends of the water passage 11; the water passage 11 includes horizontal sections 111 and curved sections 112, the horizontal sections 111 being arranged in multiple sets at vertical intervals, and the curved sections 112 being used to connect the pipe ends of adjacent horizontal sections 111; and electromagnetic excitation pipes 60, each concentrically arranged at the center of the horizontal section 111.

[0045] In one embodiment, see Figure 3 The water passage 11 is arranged in a meandering manner along the height of the treatment tank 10. It includes at least three or more sets of horizontal sections 111. The horizontal sections 111 are arranged at intervals in the vertical plane, so that the water passage 11 is arranged in the longitudinal space, thereby making full use of the height space of the treatment tank 10. An electromagnetic excitation pipe 60 is installed in the horizontal section 111 of each water passage 11. When the electromagnetic excitation pipe 60 is energized, it can effectively destroy the scale crystals in the cooling circulating water in the meandering water passage 11, ensuring the purification effect of the cooling circulating water.

[0046] In one embodiment, the processing box 10 can be either cuboid or tubular, and the water passage 11 can be arranged in a meandering manner within the cavity of the processing box 10.

[0047] In one embodiment, to ensure that the cooling circulating water flows smoothly through the entire meandering water path 11, a pump can be installed at the inlet of the water path 11. The pump can push the circulating water in the water path 11 to avoid the problem of poor circulation caused by the meandering water path 11.

[0048] In one embodiment, see Figure 7 The electromagnetic excitation circuit 60 includes a coil tube 61 and an electrode tube 62. The electrode tube 62 is located at the center of the coil tube 61, and the outer wall of the electrode tube 62 is connected to the inner wall of the horizontal section 111.

[0049] In the above embodiment, electrode tube 62 is connected to the controller via wires to generate an alternating magnetic field. The gap between electrode tube 62 and coil tube 61 allows circulating water to pass through. Coil tube 61 contains windings and is connected to the controller to generate a direct current magnetic field. The outer surface of coil tube 61 is cylindrical to facilitate connection with electrode tube 62. The inner cavity of coil tube 61 allows circulating cooling water to flow through. To ensure the regularity of the internal and external structures of coil tube 61, it can be cast into a plastic cylindrical tube, which not only meets the requirements of the internal and external structures but also achieves a seal.

[0050] Thus, the DC magnetic field generated by coil tube 61 is a constant magnetic field, whose main function is to reduce the hydrogen bond binding force of water molecules, release free water molecules, and slow down the crystallization and scale formation process. On the other hand, the alternating magnetic field generated by electrode tube 62 is a magnetic field with constantly changing magnetic poles, whose main function is to change the polarity of scale-forming ions in the water and prevent scale crystallization. The combined use of the two magnetic fields can better achieve scale prevention and removal.

[0051] In one embodiment, see Figure 4 and Figure 5 In order to fix the water passage 11 so that the entire water passage 11 is connected as a whole, multiple sets of water passage 11 are arranged at intervals along the width direction of the processing box 10. The ends of the horizontal sections 111 of the multiple sets of water passage 11 are fixed together by fixing plates 50. There are two sets of fixing plates 50.

[0052] In one embodiment, two sets of fixing plates 50 are arranged at intervals, and the fixing plates 50 are fixed at the end of the horizontal section 111 of the water channel 11. The fixing plates 50 can be fixed inside the processing tank 10 to realize the connection between multiple sets of water channels 11 and the processing tank 10.

[0053] In one embodiment, see Figure 7To implement this, radial connecting brackets 621 are provided at both ends of the electrode tube 62 and the coil tube 61. The electrode tube 62 is installed inside the coil tube 61 through the radial connecting brackets 621. The electrode tube 62 is connected to the coil tube 61 through the radial connecting brackets 621, so that a gap for cooling water to pass through can be formed between the electrode tube 62 and the coil tube 61.

[0054] Preferably, an extension tube 1121 is provided on the curved section 112, one end of the electrode tube 62 extends into the horizontal section 111 and out of the end of the extension tube 1121, and one end of the electrode tube 62 is fixed on the fixing plate 50.

[0055] In the above embodiments, see Figure 3 , Figure 4 and Figure 5 The extension tube 1121 is set on the curved section 112 and is arranged parallel to the horizontal section 111. When the electromagnetic excitation circuit 60 formed by the electrode tube 62 and the coil tube 61 is inserted into the horizontal section 111, the electrode tube 62 passes through the extension tube 1121 and the end of the extension tube 62 is fixed to the fixing plate 50. The electrode tube 62 and the coil tube 61 are electrically connected through the extended end.

[0056] In one embodiment, a sealing pad may be provided between the body of the electrode tube 62 and the extension tube 1121 to achieve a seal between the electrode tube 62 and the extension tube 1121.

[0057] In one embodiment, see Figure 1 In order to connect the inlet and outlet of the water circuit 11 with the main pipeline of the industrial cooling circulating water system, the inlet and outlet of the multiple sets of water circuits 11 are respectively provided with a first connecting pipe 12 and a second connecting pipe 13, and the first connecting pipe 12 and the second connecting pipe 13 are vertically downward.

[0058] The first connecting pipe 12 and the second connecting pipe 13 are vertically downward, so that the main pipeline of the industrial cooling circulating water system directly enters the water circuit 11 through the first connecting pipe 12 vertically upward, and then enters the main pipeline of the industrial cooling circulating water system again through the second connecting pipe 13 vertically downward.

[0059] Preferably, see Figure 2 In order to allow the cooling circulating water in the main pipeline of the industrial cooling circulating water system to enter multiple water circuits 11, the two ends of the treatment tank 10 are provided with a first sealed chamber 14 and a second sealed chamber 15. The first connecting pipe 12 is connected to the first sealed chamber 14, and the second connecting pipe 13 is connected to the second sealed chamber 15.

[0060] In one embodiment, the first sealed chamber 14 and the second sealed chamber 15 are located at both ends of the processing box 10 to form independent compartments. Multiple sets of first connecting pipes 12 are provided, and each is connected to an independent first sealed chamber 14. Cooling circulating water enters the first sealed chamber 14, enters the water circuit 11 through the first connecting pipe 12 for circulation treatment, and then is introduced into the second sealed chamber 15 through the second connecting pipe 13, and enters the main pipeline of the industrial cooling circulating water system from the second sealed chamber 15.

[0061] In one embodiment, see Figure 1 The processing tank 10 is also equipped with an inlet pipe 20 and an outlet pipe 30. The inlet pipe 20 is connected to the first sealed chamber 14, and the outlet pipe 30 is connected to the second sealed chamber 15. A first valve 21 and a second valve 31 are respectively installed on the inlet pipe 20 and the outlet pipe 30. The first valve 21 is used to close and open the inlet pipe 20, and the second valve 31 is used to close and open the outlet pipe 30. The other end of the inlet pipe 20 and the outlet pipe 30 are respectively connected to the main water pipe 40. A third valve 41 is installed on the main water pipe 40. The third valve 41 is located in the pipe body between the inlet pipe 20 and the outlet pipe 30 and the main water pipe 40.

[0062] In the above embodiments, the first valve 21 and the second valve 31 configured on the inlet pipe 20 and the outlet pipe 30, respectively, together with the third valve 41 on the main water pipe 40, form a flexible water circuit control system. When the equipment needs maintenance, only the first valve 21 and the second valve 31 need to be closed, and the third valve 41 needs to be opened to isolate the purification host equipment from the circulating water system, so that the main water pipe 40 can maintain normal water flow. This enables online maintenance of the equipment, avoiding the problems of large-scale pipeline modification and system shutdown during maintenance required by traditional solutions. It significantly improves the continuity and stability of the industrial cooling circulating water system and reduces production losses caused by downtime for maintenance.

[0063] In one embodiment, the first valve 21, the second valve 31 and the third valve 41 are all butterfly valves, and all three valves are equipped with a rotary wrench for easy opening and closing, so as to realize the opening or closing of the three sets of valves.

[0064] In one embodiment, see Figure 1 To achieve the connection between the inlet pipe 20, the outlet pipe 30 and the main water pipe 40, bypass pipes are installed at intervals along the length of the main water pipe 40. The main water pipe 40 is arranged horizontally, while the inlet pipe 20 and the outlet pipe 30 are arranged vertically, thereby achieving the conductive connection between the inlet pipe 20, the outlet pipe 30 and the main water pipe 40.

[0065] In one embodiment, the inlet pipe 20 and the outlet pipe 30 are connected to the main water pipe 40 at a distance along the length of the main water pipe 40.

[0066] To further improve the treatment effect of the electromagnetic excitation device on the circulating cooling water, the height of the inlet of the water channel 11 is lower than the height of the outlet. After the circulating cooling water is introduced into the water channel 11 through the inlet pipe 20, it enters the water channel 11 from low to high until the entire water channel 11 is filled with circulating cooling water, thus ensuring the treatment effect of the circulating cooling water.

[0067] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0068] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
