Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and particularly to an annular ferrite component, a water processor, and a water treatment system. Background Art

[0002] An electronic water processor utilizes the high-frequency alternating electromagnetic field generated by electronic components to change the physical properties of water when it passes through the water processor, breaking the associated chain-like macromolecules into single water molecules. The dipole moment of the water molecules increases, surrounding the positive and negative ions of the dissolved salts in the water, reducing the movement speed of the salt ions, decreasing the electrostatic attraction, greatly reducing the chance of collision and combination, and preventing the formation of water scale to achieve the purpose of scale prevention; and the attraction to the positive and negative salt ions increases, making the original water scale on the heating surface or the pipe wall become soft and cracked, and falling off automatically under the action of the force in the water, thus achieving the purpose of scale removal. At the same time, the microcurrent in the water destroys the living environment of microorganisms, and the active oxygen free radicals formed in the water can oxidize the cell membranes of microorganisms and destroy the dismutase of microorganisms, thereby killing the microorganisms in the water to achieve the purpose of sterilization and algae removal.

[0003] Based on this, in the related art, a method of directly providing an alternating signal to the coil is proposed, that is, the two output terminals for outputting the alternating signal are directly connected to the two ends of the coil respectively to generate an alternating electromagnetic field in the coil. However, in this technology, the heat loss generated by the coil is relatively high, and the electric field intensity is low, resulting in low water treatment efficiency and low economic benefits of water treatment.

[0034] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] The annular ferrite component, water processor, and water treatment system according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0036] Figure 1 is a schematic structural diagram of an annular ferrite component according to an embodiment of the present invention.

[0037] As Figure 1 shown, the annular ferrite component 10 includes a coil 11, a bobbin 12, and an annular ferrite 13. The coil 11 is wound around the bobbin 12, and the annular ferrite 13 passes through the inside of the bobbin 12. The two ends of the coil 11 are respectively denoted as a first terminal 1 and a second terminal 2. A third terminal 3 is led out between the first terminal 1 and the second terminal 2, and the number of turns of the coil between the first terminal 1 and the third terminal 3 and the number of turns of the coil between the second terminal 2 and the third terminal 3 are both greater than 0. The first terminal 1 and the third terminal 3 are used to electrically connect to a signal generator 20, and the insertion hole in the center of the annular ferrite 13 is used to pass through the flow pipe of the water to be treated.

[0038] In this embodiment, when performing water treatment, the toroidal ferrite 13 is wrapped around the pipeline through which the water to be treated flows, even if the pipeline passes through the toroidal ferrite 13. Then, an alternating target signal (such as a square wave signal, a sine-cosine wave signal) is generated by the signal generator 20, and the target signal is output to the coil 11. The target signal generates an alternating current in the coil 11, and the alternating current generates an alternating electromagnetic field on the toroidal ferrite 13.

[0039] In some embodiments, the number of turns N1 of the coil between the first terminal 1 and the third terminal 3 is determined according to the pipe diameter of the pipeline and the frequency of the target signal. The number of turns N2 of the coil between the second terminal and the third terminal is greater than or equal to 1, such as 3 turns, 4 turns, etc. The specific number of turns can be determined through experiments to ensure that a relatively strong alternating electromagnetic field is generated.

[0040] Specifically, the winding between the first terminal 1 and the third terminal 3 is denoted as a closed coil, and the winding between the second terminal 2 and the third terminal 3 is denoted as an open coil. The first terminal 1 and the third terminal 3 are connected to the LC resonance circuit in the signal generator 20, and the second terminal 2 is left open and suspended. An alternating current is generated in the coil 11. According to the magnetic effect of the current, an alternating electromagnetic field will be generated around the coil 11. When the alternating current is constant, the magnitudes of the induced magnetic field and the induced electric field generated by the coil 11 are also constant. When performing water treatment, the toroidal ferrite 13 passes through the inside of the skeleton 12, and the toroidal ferrite 13 wraps the pipeline. Due to the high magnetic permeability effect of the ferrite, the electromagnetic field generated by the coil 11 can be conducted to the toroidal ferrite 13. At this time, the toroidal ferrite 13 can be regarded as the primary winding, and the pipeline can be regarded as the secondary winding. The electromagnetic field generated by the primary winding generates an induced electromagnetic field (i.e., an alternating electromagnetic field) in the secondary winding. This alternating electromagnetic field acts on the medium in the pipeline to achieve the effect of scale prevention and scale removal.

[0041] It should be noted that although the non-metallic material has very little obstruction to the electromagnetic field of the ferrite, increasing the current of the coil 11 alone has a good effect on water treatment, but the power consumption is relatively large, which greatly wastes energy. Therefore, the pipeline in the present invention is made of a metal material.

[0042] For metal pipes, the magnetic field generated by the coil 11 is almost shielded by the pipes. However, due to the action of the alternating electric field, a certain amount of charge will be generated on the surface of the conductor pipes. When the influence of pipe grounding is not considered, an equal amount of opposite charge will be generated inside the pipes, and then an equal amount of electric field intensity will be generated, acting on the medium inside the pipes. When considering pipe grounding, since most pipes belong to ferrous alloys and have a certain amount of conductivity, a part of the charge generated by the pipes will be transferred to the ground, which will reduce the electric field intensity inside the pipes to a certain extent. If the electric field intensity generated on the pipe surface is weak itself, the electric field intensity reaching the inside of the pipes will also be negligible. Without increasing power consumption, in order to generate a stronger electric field inside the pipes, the present invention introduces a non-closed coil to increase the electric field intensity generated by the coil.

[0043] Specifically, the electric field intensity E generated by the coil 11 = K * N2 * E1, where K is a proportionality coefficient, which is a positive value, and E1 is the induced electric field intensity generated by the coil 11. The magnitude of the electric field intensity generated by the coil 11 is proportional to the number of turns N2 of the non-closed coil in the coil 11. Since the second terminal 2 corresponding to the non-closed coil is in an open and non-closed state, the non-closed coil does not generate current. According to the power P = U * I and I = 0, the added non-closed coil will not increase additional power consumption. Therefore, the electric field intensity inside the pipes can be increased without increasing power consumption. According to Maxwell's electromagnetic theory, an alternating electric field will generate a vortex magnetic field inside the pipes, and the induced magnetic field intensity inside the pipes will also be appropriately increased. Therefore, by introducing a non-closed coil, the present invention can greatly increase the electric field intensity, reduce energy waste, and improve the economic benefits of water treatment with almost no increase in power consumption.

[0044] The following uses experimental data to illustrate that the present invention has a better scale and fouling removal effect compared with the related technology.

[0045] As Figure 2 shown, the present invention uses coil #1, and the induced electric field intensity generated by it is denoted as E1, and the magnetic induction intensity is denoted as B1. In the related technology, coil #2 is used, and the induced electric field intensity generated by it is denoted as E2, and the magnetic induction intensity is denoted as B2. To better compare the data, the number of turns of the closed coils of coil #1 and coil #2 is the same, the inductance parameters are the same, the current connected to the closed coil is the same, the data measurement positions of the instruments are the same, and the measuring instruments all use the German Anno instrument model NF-5035. The measured electric field intensity and magnetic induction intensity data are all based on the peak data of the central part inside the ferrous pipe DN350.

[0046] Table 1

[0047] Frequency (Khz) E1 (V / m) B1 (uT) E2 (V / m) B2 (uT) 50 2100 1.5 125 0.3 70 1850 1.2 180 0.3 90 1650 1.3 140 0.4 110 1950 1.5 150 0.5 130 1850 1.6 120 0.6 150 2350 1.5 130 0.3 170 1650 1.2 130 0.5 190 1750 1.3 150 0.4 210 1850 1.2 160 0.5

[0048] The electric field strength, the force acting on a stationary charged particle is equal to the product of the electric field strength and the particle charge, and its unit is volts per meter (V / m). The magnetic induction intensity, the force acting on a charged particle with a certain velocity is equal to the vector product of the velocity and the magnetic induction intensity, and then the product of the particle charge, and its unit is tesla (T). In air, the magnetic induction intensity is equal to the magnetic field strength H multiplied by the magnetic permeability μ0, that is, B = μ0 * H.

[0049] Figures 3 - 10 The data in are partial data collected at the same position in the center of the iron pipe DN350, which are consistent with the data in Table 1 above. The number of turns of the closed coils of the two coils is the same and they have the same frequency and current. Among them, Figure 3 shows the electric field strength collected by coil #1 at a frequency of 50Khz, and the peak intensity is about 2100V / m; Figure 4 shows the magnetic induction intensity collected by coil #1 at a frequency of 50Khz, and the peak intensity is about 1500nT; Figure 5 shows the electric field strength collected by coil #2 at a frequency of 50Khz, and the peak intensity is about 125V / m; Figure 6 shows the magnetic induction intensity collected by coil #2 at a frequency of 50Khz, and the peak intensity is about 325nT; Figure 7 shows the electric field strength collected by coil #1 at a frequency of 150Khz, and the peak intensity is about 2400V / m; Figure 8 shows the magnetic induction intensity collected by coil #1 at a frequency of 150Khz, and the peak intensity is about 1500nT; Figure 9 shows the electric field strength collected by coil #2 at a frequency of 150Khz, and the peak intensity is about 170V / m; Figure 10 shows the magnetic induction intensity collected by coil #2 at a frequency of 150Khz, and the peak intensity is about 430nT.

[0050] Combined with Table 1 above and Figures 3 - 10 , through the comparative analysis of experimental data, it can be seen that coil #1 adopted in the present invention can greatly improve the electric field strength and magnetic field strength compared with coil #2 adopted in the related art, thereby improving the scale prevention and removal effect during water treatment.

[0051] In some embodiments, coil 11 includes two wires, which are respectively denoted as the first wire and the second wire. The first wire is wound around the skeleton 12. The two ends of the first wire are the first terminal 1 and the second terminal 2 respectively. One end of the second wire is electrically connected to the first wire, and the other end of the second wire serves as the third terminal 3.

[0052] In some other embodiments, the coil 11 includes a third wire and at least two wire rows. The wires of the at least two wire rows are connected in series in sequence and are wrapped around the bobbin 12. The two ends of the at least two wire rows after being connected in series are respectively a first terminal 1 and a second terminal 2. One end of the third wire is electrically connected to the wire of any one of the wire rows, and the other end of the third wire serves as a third terminal 3.

[0053] Wherein, each wire row includes the same number of wire strands, and the lengths can be different. The number of wire rows is determined according to the lengths of the wire rows and the circumference of the bobbin. The sequential connection length of the wire rows needs to be greater than the circumference of the bobbin.

[0054] Specifically, taking the coil 11 including two wire rows as an example, the two wire rows are respectively denoted as a first wire row 111 and a second wire row 112. The first end of the first wire row 111 is electrically connected to the first end of the second wire row 112, and the first end of the first wire row 111 is electrically connected to the second end of the second wire row 112. The electrical connection methods are all as Figure 11 shown. Taking the first wire row 111 and the second wire row 112 both including six wire strands as an example, referring to Figure 11 , the first end of the first wire strand of the first wire row 111 serves as the first terminal 1 of the coil 11, which is electrically connected to the first end of the first wire strand of the second wire row 112. The first end of the first wire strand of the second wire row 112 is then electrically connected to the first end of the second wire strand of the first wire row 111. The first end of the second wire strand of the first wire row 111 is then electrically connected to the first end of the second wire strand of the second wire row 112. The first end of the second wire strand of the second wire row 112 is then electrically connected to the first end of the third wire strand of the first wire row 111, and so on until the series connection is completed. After the series connection is completed, the first end of the sixth wire strand of the second wire row 112 serves as the second terminal 2 of the coil 11.

[0055] In some embodiments, as Figure 1 、 Figure 12 shown, the toroidal ferrite 13 includes a plurality of ferrite groups 131 that are mechanically connected in sequence. Each ferrite group 131 includes at least one ferrite 1311, and the bobbin 12 is threaded through any one of the ferrites 1311.

[0056] In this embodiment, any two adjacent ferrite groups are mechanically connected in a hinged manner.

[0057] For example, referring to Figure 1 、 Figure 12 , through holes are provided in the ferrites 1311 of any two adjacent ferrite groups. The through holes are used to pass through screws, and thus the ferrites 1311 of any two adjacent ferrite groups can be hinged through screws and nuts.

[0058] In some embodiments, referring to Figure 1 、 Figure 12, the number of ferrite groups 131 is an even number, such as Figure 1 in which the number is 6, Figure 12 in which the number is 8. Each ferrite group 131 includes at least one ferrite 1311, such as Figure 1 in which each ferrite group 131 includes one ferrite 1311, such as Figure 12 in which, the ferrite groups 131 are divided into two types, the two types of ferrite groups 131 are arranged at intervals, one type includes one ferrite 1311, and the other type includes two ferrite 1311. And, the spaced ferrite 1311 are located in the same plane.

[0059] Figure 13 is the structural block diagram of the water processor according to the embodiment of the present invention.

[0060] As Figure 13 shown, the water processor 100 includes a signal generator 20 and the toroidal ferrite component 10 of the above embodiment, and the signal generator is electrically connected to the first terminal 1 and the third terminal 3 of the coil 11 in the toroidal ferrite component 10.

[0061] In some embodiments, as Figure 14 shown, the signal generator 20 includes an LC resonance circuit 21, the first output terminal of the LC resonance circuit 21 is electrically connected to the first terminal 1, and the second output terminal of the LC resonance circuit 21 is electrically connected to the third terminal 3.

[0062] Among them, the LC resonance circuit 21 is used to generate an alternating target signal, such as an alternating sine wave signal or an alternating square wave signal.

[0063] Figure 15 is the structural block diagram of the water treatment system according to the embodiment of the present invention.

[0064] As Figure 15 shown, the water treatment system 1000 includes a flow-through pipe 200 for the water to be treated and the water processor 100 of the above embodiment.

[0065] For the toroidal ferrite component, water processor and water treatment system according to the embodiments of the present invention, by leading out the third terminal, connecting it to the first terminal to access the signal generator to receive the alternating target signal, and leaving the second terminal vacant, the electric field strength can be increased without increasing the power consumption, thereby reducing energy waste and improving the economic benefits of water treatment.
