Description

Technical Field

[0001] This invention relates to the field of industrial circulating water treatment equipment, specifically to an electromagnetic emission water treatment device. Background Technology

[0002] In modern industry and engineering, industrial circulating water cooling systems are essential for heat exchange in large equipment. However, these systems face the problem of pipe scaling, which not only reduces heat exchange efficiency but also causes corrosion and other problems that damage the circulating water system.

[0003] In existing technologies, high-frequency electromagnetic field water treatment technology can be used for descaling and scale inhibition. High-frequency electromagnetic field water treatment generates a high-frequency electromagnetic field by passing a high-frequency current through an electromagnetic emission electrode group. After circulating water flows through the high-frequency electromagnetic field, it absorbs the energy of the high-frequency electromagnetic field, which changes the physical properties of the circulating water, thereby altering the crystal state or particle size of calcium carbonate, thus achieving the purpose of scale inhibition and descaling.

[0004] Patent document CN211170082U discloses a novel high-frequency electromagnetic water treatment device, including a high-frequency electromagnetic field power source array chassis, emitting electrodes, and an auxiliary main pipeline. The auxiliary main pipeline is a circular pipe of equal diameter, with multiple parallel branch pipes inside. Each branch pipe is completely open at both ends, and flanges are provided at both ends of the auxiliary main pipeline, connecting to the user's circulating water pipeline. The emitting electrodes are respectively installed in the branch pipes, and coaxial cables leading from the emitting electrodes are connected to the high-frequency electromagnetic field power source array via conduits. In this high-frequency electromagnetic water treatment device, each emitting electrode has an independent conduit. When the number of emitting electrodes is large, the number of conduits is also large. A large number of conduits can obstruct the flow of circulating water in the auxiliary main pipeline, thereby reducing the flow rate of the circulating water and resulting in a decrease in heat exchange efficiency.

[0005] In addition, patent document CN218262170U discloses an energy conversion rod for a carbon-silicon-sulfur purifier, including an emitter, an emitter base, and an outlet tube. The emitter base is sealed to the carbon-silicon-sulfur purifier body by a sealing screw. The sealing screw contains a sealing ring, and the outlet tube is equipped with a rubber seal to prevent water from entering. The sealing ring and rubber seal are prone to aging, posing a risk of water leakage. Moreover, the emitter is a copper rod, making it difficult to adjust its impedance matching. Summary of the Invention

[0006] The purpose of this invention is to provide an electromagnetic emission water treatment device that can improve scale inhibition and significantly increase the conversion efficiency of the emission electrode.

[0007] To achieve the above objectives, the present invention provides an electromagnetic emission water treatment device, comprising a high-frequency electromagnetic field power source array chassis, a main pipe, multiple branch pipes, multiple cables, and multiple emission electrode assemblies. The multiple branch pipes are all disposed within the main pipe, and the emission electrode assemblies are arranged in a one-to-one correspondence with the branch pipes. The emission electrode assemblies are disposed within the branch pipes and connected to the high-frequency electromagnetic field power source array chassis via cables. A conduit is disposed within the main pipe, with its first end extending outwards from the outside of the main pipe and its second end connected to at least two emission electrode assemblies. The cables of the two emission electrode assemblies are each disposed within the conduit. Each emission electrode assembly includes a receiving tube and a traveling wave antenna. The traveling wave antenna is connected to the cables and is wound into a cylindrical shape and disposed within the receiving tube. The receiving tube is also filled with a filler for fixing the traveling wave antenna.

[0008] As can be seen from the above scheme, by placing the cables of at least two transmitting electrode assemblies in the same conduit, it is beneficial to reduce the number of conduits in the main pipe, thereby reducing the resistance of the conduits to water flow, ensuring the water flow speed, and improving heat exchange efficiency. By setting a circular tubular traveling wave antenna with a broadband conical mode, the phase velocity of the traveling wave will automatically adjust to maintain enhanced directivity, thus obtaining an approximately ideal circularly polarized electromagnetic field. The impedance is approximately equal to pure resistance, and the phase velocity automatically changes linearly with frequency to maintain enhanced directivity. The absolute bandwidth of the traveling wave antenna can be greatly improved. When the high-frequency current flows along the traveling wave antenna, the electromagnetic energy is constantly being consumed in the process of radiating electromagnetic energy. Only a small amount of electromagnetic energy can reach the end of the traveling wave antenna, which effectively prevents the generation of reflected waves. This is beneficial to significantly improve the ability of high-frequency current to convert electromagnetic waves, reduce power consumption, and reduce the operating cost of the equipment.

[0009] A further approach is to fabricate the traveling wave antenna using a thin sheet, which is a conductive metal sheet.

[0010] A further option is that the transmitting electrode assembly also includes a cap, which is connected to the end of the receiving tube away from the conduit, and the cap and the receiving tube are sealed and fixedly connected by thermofusion welding.

[0011] As can be seen from the above scheme, fixing the cap by hot-melt welding helps to ensure the seal between the cap and the receiving tube, thus improving the waterproof effect.

[0012] A further embodiment includes a T-junction on the conduit, with a first connector at the first end of the T-junction; a second connector on the transmitting electrode assembly, which is connected to the end of the receiving tube near the conduit. The second connector includes a pipe fitting, a fixing sleeve, and a nut. The two ends of the pipe fitting are connected to the receiving tube and the fixing sleeve, respectively, with the fixing sleeve protruding outward from the pipe fitting. The nut is movably connected to the fixing sleeve. The second connector is connected to the first connector via the nut. The cable passes through the first and second connectors, is inserted into the nut, and is connected to the traveling wave antenna.

[0013] As can be seen from the above scheme, by setting a T-shaped conduit, it is convenient to install two or more cables in the same conduit; by setting the first connector and the nut threaded connection, it not only has the advantages of convenient and quick installation and disassembly, but also does not require rotating the second connector and the transmitting electrode assembly during connection, thus avoiding the cable inside the receiving tube from getting tangled with the traveling wave antenna due to continuous rotation of the receiving tube in one direction during installation, thereby avoiding damage or destruction to the cable and the traveling wave antenna.

[0014] A further option is that the first connector has a boss and a sealing ring at the end away from the tee pipe, with the sealing ring fitted onto the boss; the end of the fixing sleeve has an annular flange, which is sealed to the sealing ring.

[0015] As can be seen from the above scheme, by setting the boss part, the deformation of the sealing ring can be withstood; by setting the sealing ring for sealing connection with the annular flange, it is beneficial to improve its sealing performance and give it excellent waterproof performance.

[0016] A further option is that the first end of the tee is fixedly connected to the first connector through a tapered pipe threaded connection structure; the second end and the third end of the tee are both fixedly connected to the conduit through a tapered pipe threaded connection structure.

[0017] As can be seen from the above scheme, the tee pipe and the first connector are connected by a tapered pipe thread connection structure, which has the advantages of anti-aging, anti-leakage and longer service life compared with the solution of sealing with a sealing ring.

[0018] A further option is to fix the receiving tube and the second connector by hot-melt welding.

[0019] A further approach is to arrange multiple shunt tubes in at least one row, with all the emitting electrode assemblies in all shunt tubes in the same row connected to the same conduit.

[0020] As can be seen from the above scheme, optimizing the arrangement of the diversion pipes helps to simplify the number and direction of the conduits, thereby reducing the obstruction of water flow.

[0021] A further approach is to have the transmitting electrode assembly coaxially arranged with the corresponding shunt tube, and to arrange adjacent shunt tubes in an externally tangential manner.

[0022] As can be seen from the above scheme, arranging two adjacent branch pipes in an external tangential manner is beneficial for facilitating the installation of more branch pipes within the main pipe, thereby improving its efficiency. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] See also Figure 1 and Figure 2This embodiment provides an electromagnetic emission water treatment device, including a main control box 1, a high-frequency electromagnetic field power source array chassis 2, a main pipe 3, multiple branch pipes 4, multiple cables 5, and multiple emitting electrode assemblies 6. The main control box 1 is electrically connected to the high-frequency electromagnetic field power source array chassis 2 via a communication cable. The main control box 1 is equipped with a display screen and buttons, which can control the high-frequency electromagnetic field power source array chassis 2 to dynamically adjust to a suitable electromagnetic field energy to generate electromagnetic field energy that meets the requirements of circulating water treatment. Flanges are provided at both ends of the main pipe 3, allowing it to be connected to the user's circulating water pipeline.

[0037] The high-frequency electromagnetic field power source array housing 2 is located outside the main pipe 3. Multiple branch pipes 4 are arranged parallel to each other inside the main pipe 3. The branch pipes 4 are made of thin steel pipes, and their two ends are connected for circulating water flow. Emitting electrode assemblies 6 are arranged one-to-one with the branch pipes 4, and are housed inside the branch pipes 4. Preferably, the transmitting electrode assemblies 6 and the branch pipes 4 are coaxially arranged. Each transmitting electrode assembly 6 is electrically connected to the high-frequency electromagnetic field power source array housing 2 via a cable 5.

[0038] The main pipe 3 is also equipped with several conduits 7, preferably metal water pipes. The first end of the conduit 7 extends out of the main pipe 3 and into the high-frequency electromagnetic field power source array chassis 2. The second end of the conduit 7 is connected to at least two transmitting electrode assemblies 6, and the respective cables 5 of the two transmitting electrode assemblies 6 are arranged in the same conduit 7. One end of the cable 5 is electrically connected to the high-frequency electromagnetic field power source array chassis 2, and the other end of the cable 5 is electrically connected to the transmitting electrode assembly 6. Compared with the prior art, the cable 5 in this embodiment does not need to be connected to the BNC socket of the base. BNC socket is a coaxial cable connector.

[0039] See also Figures 3 to 6 and combined Figure 2 A three-way pipe 8 is provided at the center of the corresponding shunt pipe 4 in the conduit 7. The transmitting electrode assembly 6 is connected to the three-way pipe 8 and is coaxially arranged with the shunt pipe 4. Specifically:

[0040] A first connector 9 is provided at the first end of the tee pipe 8. The first connector 9 is made of 304 stainless steel. One end of the first connector 9 is fixedly connected to the first end of the tee pipe 8 through a tapered pipe thread connection structure. This eliminates the need for fillers and sealing rings, relying on the deformation of the tapered pipe thread profile to ensure the tightness of the threaded connection. This avoids the leakage problem caused by the aging of rubber sealing rings used in ordinary pipe threads, thus improving the reliability of the equipment and reducing production difficulty. At the end of the first connector 9 furthest from the tee pipe 8, a first threaded connection structure 92, a boss 93, and a sealing ring 91 are provided. The boss 93 protrudes from the end face of the first connector 9, and its outer diameter is smaller than the outer diameter of the thread of the first threaded connection structure 92, forming a stop surface between them. The sealing ring 91 is fitted onto the boss 93 and abuts against the stop surface. In this embodiment, the sealing ring 91 is preferably made of polytetrafluoroethylene or copper to avoid the leakage problem caused by the aging of rubber sealing rings.

[0041] A second connector 10, made of 304 stainless steel, is provided on the transmitting electrode assembly 6. The second connector 10 is used to connect with the first connector 9. Specifically, the second connector 10 includes a pipe fitting 101, a fixing sleeve 102, and a nut 103. The first end of the pipe fitting 101 is fixedly connected to the fixing sleeve 102, and a portion of the fixing sleeve 102 protrudes beyond the outer side of the pipe fitting 101. An annular flange 1021 is provided at the protruding end of the fixing sleeve 102, protruding from the outer peripheral wall of the fixing sleeve 102. The nut 103 is movably connected to the fixing sleeve 102 and can move and rotate between the pipe fitting 101 and the annular flange 1021. The second connector 10 is detachably connected to the first connector 9 via the nut 103. A second threaded connection structure is provided on the inner side of the nut 103, which engages with the first threaded connection structure 92. During installation, the nut 103 can be rotated alone without rotating the transmitting electrode assembly 6, thus completing the installation. This avoids damage caused by the internal cables becoming entangled with the traveling wave antenna due to continuous rotation of the transmitting electrode assembly 6 in one direction during installation. After the first threaded connection structure 92 and the nut 103 are in place, the annular flange 1021 and the sealing ring 91 form a sealed connection, which improves the sealing performance and provides excellent waterproofing.

[0042] The first connector 9, the fixing sleeve 102, and the pipe fitting 101 are all hollow structures. The cable 5 passes through the first connector 9, the nut 103, and the fixing sleeve 102, is inserted into the pipe fitting 101, and is connected to the traveling wave antenna 62.

[0043] During the water treatment process, the pressure inside the main pipe 3 is greater than the external atmospheric pressure. The inside of the transmitting electrode assembly 6 is connected to the outside of the main pipe 3 through a conduit. That is to say, the external pressure of the first connector 9 and the second connector 10 is greater than their internal pressure. The sealing ring 91 can effectively prevent water from entering the transmitting electrode assembly 6. The protrusion 93 not only solves the installation of the sealing ring 91, but also can withstand the deformation of the sealing ring 91, ensuring its sealing performance.

[0044] The second and third ends of the tee pipe 8 are fixedly connected to the conduit pipe 7 through a tapered threaded connection structure. Compared with the sealing method using a sealing ring, it has the advantages of anti-aging, anti-leakage and longer service life.

[0045] See also Figures 7 to 9 The other end of the connector 101 is connected to the transmitting electrode assembly 6. The transmitting electrode assembly 6 includes a receiving tube 61, a traveling wave antenna 62, and a cap 63. The receiving tube 61 is preferably a PPR tube. One end of the receiving tube 61 is sealed to the connector 101 by thermofusion welding, and the other end of the receiving tube 61 is provided with a cap 63. To improve the sealing performance between the receiving tube 61 and the cap 63, the cap 63 is fixedly connected to the receiving tube 61 by thermofusion welding. This embodiment uses thermofusion welding technology and a tapered pipe thread connection structure to ensure reliable waterproof sealing. This embodiment also has the advantages of simple structure, easy manufacturing, greatly enhanced applicability to production and assembly, and significant reduction in the manufacturing cost of the transmitting electrode assembly.

[0046] The traveling-wave antenna 62 is made of a thin sheet, preferably a 0.12mm thick copper sheet, which is a conductive metal sheet. The copper sheet-based traveling-wave antenna is planar, with its feed point welded to the cable 5 at one end. It is then wound into a hollow cylindrical shape and placed inside the receiving tube 61. The diameter of the cylindrical traveling-wave antenna 62 is slightly smaller than the inner diameter of the receiving tube 61, so that the outer wall of the antenna 62 is adjacent to the inner wall of the receiving tube 61. The receiving tube 61 is also filled with a polymer filler to fix the traveling-wave antenna 62. The cylindrical traveling-wave antenna 62 can significantly improve the ability to convert high-frequency current into electromagnetic waves, reduce power consumption, and lower equipment operating costs.

[0047] In this embodiment, the cable 5 is preferably a coaxial cable 5, which includes a central conductor, an inner insulating layer, a shielding layer and an outer insulating layer from the inside to the outside. The traveling wave antenna 62 is electrically connected to the central conductor.

[0048] See also Figures 10 to 12 Within the main pipe 3, multiple branch pipes 4a / 4b / 4c are arranged in at least one row, so that the transmitting electrode assemblies 6a / 6b / 6c in all branch pipes 4a / 4b / 4c in the same row can be connected through the same conduit, thereby optimizing the routing and number of conduits and reducing obstruction to water flow.

[0049] The number of shunt tubes 4a / 4b / 4c can be set to three, seven, nine or more. When there are three shunt tubes 4a, two of them are arranged in a row; when there are seven shunt tubes 4b, they can be arranged in three rows; when there are nine shunt tubes 4c, they can be arranged in three rows.

[0050] Regardless of the number of diversion pipes 4a / 4b / 4c, the following rule is generally followed: adjacent diversion pipes 4a / 4b / 4c are arranged in an externally tangential manner to facilitate the placement of the optimal number of diversion pipes 4a / 4b / 4c within the main pipe 3a / 3b / 3c, thereby increasing the proportion of water entering the diversion pipes 4a / 4b / 4c and maximizing the alteration of more water's physical properties to improve conversion efficiency.

[0051] In summary, this invention, by placing the cables of at least two transmitting electrode assemblies within the same conduit, reduces the number of conduits in the main pipe, thereby reducing the resistance of the conduits to water flow, ensuring water flow velocity, and improving heat exchange efficiency. By using a circular tubular traveling wave antenna with a broadband conical mode, the phase velocity of the traveling wave automatically adjusts to maintain enhanced directivity, resulting in a near-ideal circularly polarized electromagnetic field. The impedance is approximately equal to pure resistance, and the phase velocity automatically changes linearly with frequency to maintain enhanced directivity. This significantly increases the absolute bandwidth of the traveling wave antenna. As the high-frequency current flows along the traveling wave antenna, the electromagnetic energy is continuously radiated and consumed, with only a small amount reaching the end of the antenna. This effectively prevents the generation of reflected waves, greatly enhancing the ability of high-frequency current to convert to electromagnetic waves, reducing power consumption, and lowering equipment operating costs.

[0052] Finally, it should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
