[0040] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0041] The water treatment device and water treatment system according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, the water treatment device 100 includes: a signal generator 101, an excitation coil 104, and a non-closed coil winding 106. The non-closed coil winding 106 is wrapped around the outer wall of a pipe 107 through which the water to be treated flows. The signal generator 101 is electrically connected to the excitation coil 104, and the excitation coil 104 is also electrically connected to the non-closed coil winding 106.

[0043] In this embodiment, the signal generator 101 outputs an alternating target signal to the excitation coil 104, and an electromagnetic signal is generated in the excitation coil 104, which is connected to the non-closed coil winding 106 to induce an electromagnetic induction signal inside the pipeline 107, thereby treating the water flowing through the pipeline 107.

[0044] The water treatment device 100 can improve the electric field strength and the magnetic field strength inside the pipeline, thereby improving the scale inhibition and removal effect.

[0045] In some embodiments, the non-closed coil winding 106 is insulated from the pipeline 107. Referring to Figure 1 , the excitation coil 104 has at least three terminals, respectively denoted as a first terminal 1, a second terminal 2, and a third terminal 3. The signal generator 101 is electrically connected to the first terminal 1 and the third terminal 3 of the excitation coil 104 (e.g., through the double-wire 103). The second terminal 2 of the excitation coil 104 is electrically connected to one end of the non-closed coil winding 106 (e.g., through the single-wire 105). The other end of the non-closed coil winding 106 is left empty.

[0046] The pipeline 107 can be a metal pipeline or a non-metal pipeline. Referring to Figure 1 , the signal generator 101 is provided with a power interface 102 for connecting an external power supply to supply power to the signal generator 101.

[0047] In this embodiment, the signal generator 101 outputs an alternating target signal (e.g., a square wave signal, a sine wave signal, etc.) to the excitation coil 104, and an electromagnetic signal is generated in the excitation coil 104, which is connected to the non-closed coil winding 106. Based on the principle of electromagnetic induction, the non-closed coil winding 106 can induce an electromagnetic induction signal inside the pipeline 107.

[0048] Specifically, the water treatment device 100, by the setting of the excitation coil 104 and the non-closed coil winding 106, can generate a high-frequency high-voltage electromagnetic field acting on the outside of the pipeline 107. For metal pipelines (such as iron pipelines), the magnetic field in the high-frequency high-voltage alternating electromagnetic field is shielded by the pipeline 107, and the high-frequency magnetic field generated by the non-closed coil winding 106 cannot enter the inside of the pipeline 107. The high-frequency alternating electric field generates a certain amount of electric charge q on the outer wall of the pipeline 107, and the electric charge q induces an equal and opposite electric charge -q inside the pipeline 107. Thus, the direction of the electric charge is alternately changed, so that an alternating high-frequency electric field is formed inside the pipeline 107. According to Maxwell's electromagnetic field theory, an alternating electric field can induce a magnetic field, so that a certain intensity of magnetic field is also formed inside the pipeline 107. Thus, the water treatment device 100 of the present application can realize the electromagnetic field intensity of the metal pipeline, and improve the use effect of scale removal and scale inhibition. Moreover, compared with the electromagnetic scale removal device of the energy coupling ring, the water treatment device 100 of the present application has relatively low cost. For non-metal pipelines, the high-frequency electromagnetic field generated by the non-closed coil winding 106 can directly pass through the pipeline 107, and a very strong electromagnetic field can be directly formed inside the pipeline 107, improving the use effect of scale removal and scale inhibition of water treatment.

[0049] In some embodiments, the structure of the excitation coil 104 can be as shown in FIG. 2(a). The excitation coil 104 includes one coil, denoted as a first coil 1041. The two ends of the first coil 1041 are a first end 1 and a second end 2, respectively. A third end 3 is led out between the first end 1 and the second end 2. The number of turns N1 between the first end 1 and the third end 3 and the number of turns N2 between the second end 2 and the third end 3 are both greater than 0, and the specific data can be determined by experiment to ensure that a high-intensity alternating electromagnetic field is generated.

[0050] Specifically, the winding between the first end 1 and the third end 3 is referred to as a closed coil, and the winding between the second end 2 and the third end 3 is referred to as a non-closed coil. The first end 1 is connected to the signal generator 101, and the second end 2 is connected to one end of the non-closed coil winding 106 through the single wire 105. The sine wave signal or square wave signal generated by the signal generator 101 is connected to the excitation coil 104. The electromagnetic signal generated by the excitation coil 104 is connected to one end of the non-closed coil winding 106 on the outer wall of the pipeline 107 through the single wire 105. The other end of the non-closed coil winding 106 is open, and the non-closed coil winding 106 is insulated from the pipeline, forming a structure similar to a transformer. The non-closed coil winding 106 serves as the primary winding, and the pipeline 107 serves as the secondary winding. Thus, the electromagnetic field generated by the primary winding induces an electromagnetic induction signal (i.e., an alternating electromagnetic field) in the secondary winding. The alternating electromagnetic field acts on the medium in the pipeline 107, achieving the effect of scale removal and scale inhibition.

[0051] In some embodiments, the excitation coil 104 includes two coils, respectively denoted as a second coil 1042 and a third coil 1043, two ends of the second coil 1042 are respectively the first end 1 and the third end 3, one end of the third coil 1043 is the second end 2, and the other end of the third coil 1043 is denoted as a fourth end 4.

[0052] In this embodiment, the fourth end 4 can be grounded; or can be electrically connected with a non-closed coil winding 106, for example, as shown in FIG. 2(c), the number of non-closed coil windings 106 is two, and the second end 2 and the fourth end 4 are respectively electrically connected with a non-closed coil winding 106.

[0053] In some embodiments, the signal generator 101 includes a square wave circuit, and the square wave circuit is configured to generate a square wave signal as the target signal.

[0054] In some other embodiments, the signal generator 101 not only includes a square wave circuit, but also includes a waveform conversion circuit, and the waveform conversion circuit is configured to convert the square wave signal into a sine wave signal as the target signal, and the waveform conversion circuit includes a capacitor to form an LC oscillation circuit with the excitation coil 104.

[0055] In some embodiments, the excitation coil 104 is a voltage-adjustable excitation coil, and the output energy of the excitation coil 104 can be adjusted according to the pipe diameter of the pipeline 107.

[0056] Specifically, the output energy of the excitation coil 104 is positively correlated with the pipe diameter of the pipeline 107. That is, the larger the pipe diameter of the pipeline 107, the larger the output energy of the excitation coil 104 required, and the smaller the pipe diameter of the pipeline 107, the smaller the output energy of the excitation coil 104 required. It should be noted that if the pipeline 107 is grounded, the output energy of the excitation coil 104 required is also large, and if the pipeline 107 is not grounded, the output energy of the excitation coil 104 required is small.

[0057] In some embodiments, the inductance parameter of the excitation coil 104 and / or the frequency of the square wave signal is determined according to the output energy of the excitation coil 104.

[0058] Specifically, the water treatment device 100 utilizes the principle of electromagnetic induction, outputs a square wave signal or a sine wave signal through the signal generator 101, and accesses the excitation coil 104. In actual use, in the case that the square wave frequency is fixed, the inductance parameter of the excitation coil 104 can be adjusted according to the actual size of the pipe diameter of the pipeline 107, so that the resonant frequency is close to the square wave frequency.

[0059] Taking the signal generator 101 including the square wave circuit and the waveform conversion circuit as an example, when the frequency of the square wave output by the square wave circuit is equal to the resonance frequency of the LC oscillation circuit, the equivalent internal resistance of the LC oscillation circuit is minimum, the power is maximum, and the output energy is strongest. Based on this, the inductance parameter of the excitation coil 104, i.e., the L value of the LC oscillation circuit, can be adjusted according to the square wave frequency; and the output energy of the excitation inductor 104 can determine the square wave frequency. It should be noted that this theory also applies to the example that the signal generator 101 includes the square wave circuit and outputs the square wave signal to the excitation coil 104.

[0060] Meanwhile, the number of turns of the non-closed coil winding 106 is different, and the induced electric field strength is also different. Therefore, the number of turns of the non-closed coil winding 106 can also be adjusted to improve the energy output and thus improve the electric field strength. The number of turns of the non-closed coil winding 106 can be adjusted in the range of 1-N turns, and N is an infinite value.

[0061] In some embodiments, the number of the non-closed coil windings 106 is multiple, and one end of each of the multiple non-closed coil windings 106 is electrically connected to the second end 2 of the excitation coil 104.

[0062] Specifically, the multiple non-closed coil windings 106 can all be wound on the outer wall of the same pipe 107, and the distance between adjacent two non-closed coil windings 106 can not be limited, such as 1 centimeter, 10 centimeters, etc. When the excitation coil 104 adopts the structure shown in FIG. 2(a), the second end 2 of the excitation coil 104 can be connected to one end of each of the multiple non-closed coil windings 106 through the multiple single wires 105; when the excitation coil 104 adopts the structure shown in FIG. 2(b), the second end 2 of the excitation coil 104 can be connected to one end of each of the multiple non-closed coil windings 106 through the multiple single wires 105, and the fourth end 4 of the excitation coil 104 is grounded.

[0063] In some embodiments, when the excitation coil 104 adopts the structure shown in FIG. 2(b), the second end 2 of the excitation coil 104 can be connected to one end of each of the K1 non-closed coil windings 106 through the K1 single wires 105, and the fourth end 4 of the excitation coil 104 can be connected to one end of each of the K2 non-closed coil windings 106 through the K2 single wires 105. Wherein, K1 and K2 are positive integers.

[0064] It should be noted that, in order to ensure the scale prevention and removal effect, the same direction of the multiple non-closed coil windings 106 needs to be paid attention to, otherwise the superposition and cancellation of the high-frequency electromagnetic field will occur, the energy loss will be increased, and the use effect will be reduced. Therefore, one end of the multiple non-closed coil windings 106 connected with the second end 2 of the excitation coil 104 is the like end of the multiple non-closed coil windings 106, and the like end can be determined according to the winding sequence direction of each non-closed coil winding 106 on the pipeline 107.

[0065] In some other embodiments, the number of the non-closed coil windings 106, the excitation coil 104 and the signal generator 101 is multiple, and the excitation coil 104 and the signal generator 101 are one-to-one corresponding. Each signal generator 101 is electrically connected with the first end 1 and the third end 3 of the corresponding excitation coil 104, and the second end 2 of each excitation coil 104 is electrically connected with one end of one or more non-closed coil windings 106.

[0066] Specifically, the multiple non-closed coil windings 106 can all be wound around the outer wall of the same pipeline 107, and the distance between the adjacent two non-closed coil windings 106 can not be limited, such as 1 cm, 10 cm, etc. In order to ensure the scale prevention and removal effect, one end of the non-closed coil winding 106 connected with the second end 2 of the excitation coil 104 is the like end, and the like end can be determined according to the winding sequence direction of each non-closed coil winding 106 on the pipeline 107.

[0067] In this embodiment, one excitation coil 104, one signal generator 101 and one non-closed coil winding 106 can be set as a group. For each group, when the excitation coil 104 adopts the structure shown in FIG. 2(a), the second end 2 of the excitation coil 104 of the group can be connected with one end of the non-closed coil winding 106 of the group through one single wire 105; when the excitation coil 104 adopts the structure shown in FIG. 2(b), the second end 2 of the excitation coil 104 of the group is connected with one end of the non-closed coil winding 106 of the group through one single wire 105, and the fourth end 4 is grounded.

[0068] Optionally, the excitation coil 104, the signal generator 101 and the plurality of non-closed coil windings 106 can also be set as a group. For each group, when the excitation coil 104 adopts the structure shown in Figure 2(a), the second end 2 of the excitation coil 104 of the group can be connected to one end of the plurality of non-closed coil windings 106 of the group through a plurality of single wires 105 respectively; when the excitation coil 104 adopts the structure shown in Figure 2(b), the second end 2 of the excitation coil 104 of the group is connected to one end of the plurality of non-closed coil windings 106 of the group through a plurality of single wires 105 respectively, and the fourth end 4 is grounded, or the second end 2 of the excitation coil 104 of the group can be connected to one end of one or more non-closed coil windings 106 through one or more single wires 105 respectively, and the fourth end 4 of the excitation coil 104 can be connected to one end of one or more non-closed coil windings 106 through one or more single wires 105 respectively.

[0069] Figure 3 is a structural block diagram of the water treatment system of an embodiment of the present application.

[0070] As shown in Figure 3 , the water treatment system 300 comprises a pipeline 107 through which water to be treated flows and the water treatment device 100 of the above-mentioned embodiment.

[0071] The following experimental data show that the effect of scale prevention and removal of the present application is better than that of the related art.

[0072] For better data comparison, the electric field and magnetic induction intensity data measured in the table are based on the data of the central part of the iron pipeline DN200 and are peak data, and the instrument used is a German Anno instrument model NF-5035. Among them, the electric field intensity generated by the water treatment device 100 of the present application is denoted as E1, and the magnetic induction intensity is denoted as B1; the electric field intensity generated by the closed coil of the water treatment device in the related art is denoted as E2, and the magnetic induction intensity is denoted as B2.
