Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and particularly to a water treatment device and a water treatment system. Background Art

[0002] In industrial and civil facilities, scale formation generally occurs in heat pipelines with water as the medium. Scale can affect the heat exchange efficiency of the heat exchange system in the heat station and even affect the normal operation of equipment. To solve the scale problem, physical methods are adopted in related technologies, such as electromagnetic methods for scale prevention and removal, including the winding electromagnetic method and the electromagnetic method of energy coupling rings.

[0003] However, the winding electromagnetic method has a small action range, and the formed magnetic field is strong while the electric field is weak. For iron pipelines, most of the magnetic field is shielded by the pipeline, and only a very weak electric field reaches the inside of the pipeline. The magnetic field energy that can truly reach the inside of the pipeline is very small, resulting in a large amount of magnetic field energy loss. For the electromagnetic method of energy coupling rings, the cost of the energy coupling rings is too high, and the magnetic field generated by the energy coupling rings is also shielded by iron pipelines, with low economic benefits and low scale prevention and removal efficiency.

[0025] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the 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 drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] 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.

[0027] As Figure 1 shown, the water treatment device 100 includes: a signal generator 101, an excitation coil 104, and a conductive structure 106. The signal generator 101 is electrically connected to the excitation coil 104, and the excitation coil 104 is connected to the conductive structure 106.

[0028] In this embodiment, the signal generator 101 outputs an alternating target signal to the excitation coil 104, generates an electromagnetic signal in the excitation coil 104, and the electromagnetic signal is connected to the conductive structure 106. The conductive structure 106 acts on the water transmission component 107 that needs to prevent and remove scale, so that an electromagnetic field is induced inside the water transmission component 107 for electromagnetic scale prevention and removal.

[0029] The water treatment device 100 can generate a high-frequency and high-voltage electric potential that directly acts on the internal medium of the water transmission component, thereby solving the shielding energy loss brought by the water transmission component to the magnetic field and improving the scale inhibition and removal effect.

[0030] In some embodiments, see Figure 1 , the conductive structure 106 is directly placed inside the water transmission component 107 (such as a pipeline) and is insulated from the water transmission component 107. The excitation coil 104 has at least three terminals, denoted as the first terminal 1, the second terminal 2, and the third terminal 3 respectively. The signal generator 101 is electrically connected to the first terminal 1 and the third terminal 3 of the excitation coil 104 (such as electrically connected through a twin wire 103), and the second terminal 2 of the excitation coil 104 is electrically connected to the conductive structure 106 (such as electrically connected through a single wire 105).

[0031] Among them, the water transmission component 107 can be a metal pipeline, a non-metal pipeline, or other components that can wrap the water flow. See Figure 1 , a power supply interface 102 is provided on the signal generator 101, and the power supply interface 102 is used to connect to an external power supply to supply power to the signal generator 101.

[0032] In this embodiment, the signal generator 101 outputs an alternating target signal (such as a square wave signal, a sine-cosine wave signal, etc.) to the excitation coil 104, generates an electromagnetic signal in the excitation coil 104, and the electromagnetic signal is connected to the conductive structure 106. Based on the principle of electromagnetic induction, the conductive structure 106 can induce an electromagnetic field inside the water transmission component 107.

[0033] Specifically, for the water treatment device 100, the target signal generated by the signal generator 101 is connected to the excitation coil 104 to generate a high-frequency high-voltage electromagnetic field. This electromagnetic field is led out through the single wire 105 and directly introduced into the conductive structure 106 inside the water transmission component 107 through the single wire 105, causing the conductive structure 106 to generate a strong electromagnetic field signal, which directly acts on the medium inside the water transmission component 107 for water treatment. In the related art, the electromagnetic scale inhibitor uses an energy coupling ring or a winding method on the outer side of the pipeline, with a short action distance and a short treatment time for the flowing medium, resulting in poor use effects. Moreover, for metal pipelines, in the related art, when using an energy coupling ring or a winding scheme on the outer side of the pipeline, almost all the generated magnetic fields are shielded by the metal pipelines, causing a large amount of energy loss, and the electromagnetic field reaching the inside of the pipeline is very weak, with a very poor scale and fouling removal effect and low economic benefits. However, through the settings of the excitation coil 104 and the conductive structure 106 in the present invention, the problem of short treatment time for the flowing medium can be solved; when the water transmission component 107 is a metal pipeline, the problem of magnetic field shielding by the metal pipeline can be solved, the electromagnetic field intensity inside the pipeline can be increased, the problem of magnetic field energy waste in the related art can be solved, the scale and fouling removal effect can be improved, and the economic benefits can be increased.

[0034] In some embodiments, the structure of the excitation coil 104 can be as shown in Fig. 2(a). The excitation coil 104 includes a coil, denoted as the first coil 1041. The two ends of the first coil 1041 are respectively the first end 1 and the second end 2, and a third end 3 is led out between the first end 1 and the second end 2. Among them, the number of turns N1 of the coil between the first end 1 and the third end 3 and the number of turns N2 of the coil between the second end 2 and the third end 3 are both greater than 0, and the specific data can be determined through experiments to ensure the generation of a relatively strong alternating electromagnetic field.

[0035] Specifically, the winding between the first end 1 and the third end 3 is denoted as a closed coil, the winding between the second end 2 and the third end 3 is denoted as an open coil. The first end 1 and the third end 3 are connected to the signal generator 101, and the second end 2 is connected to one end of the conductive structure 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, and the electromagnetic signal generated by the excitation coil 104 is connected to the conductive structure 106 placed inside the water transmission component 107 through the single wire 105. This conductive structure 106 generates a strong electromagnetic field signal, which can directly act on the medium inside the water transmission component 107.

[0036] In some other embodiments, as shown in Fig. 2(b), the excitation coil 104 includes two coils, denoted as the second coil 1042 and the third coil 1043 respectively. The 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 the fourth end 4.

[0037] In this embodiment, the fourth terminal 4 can be grounded; or it can be electrically connected to a conductive structure 106. At this time, the number of conductive structures 106 is two, and the second terminal 2 and the fourth terminal 4 are respectively electrically connected to a conductive structure 106. There is a certain distance between the two conductive structures 106.

[0038] In some embodiments, the signal generator 101 includes a square wave circuit, and the square wave circuit is used to generate a square wave signal as the target signal.

[0039] In other embodiments, the signal generator 101 not only includes a square wave circuit, but also includes a waveform conversion circuit. The waveform conversion circuit is used to convert the square wave signal into a sine wave signal as the target signal. The waveform conversion circuit includes a capacitor to form an LC oscillation circuit with the excitation coil 104.

[0040] In some embodiments, the excitation coil 104 is an adjustable-voltage excitation coil, and the output energy of the excitation coil 104 can be adjusted according to actual needs, such as the pipe diameter of the water transmission component 107.

[0041] Taking the water transmission component 107 as a pipeline as an example, the output energy of the excitation coil 104 is positively correlated with the pipe diameter of the pipeline. That is, when the pipe diameter of the pipeline is large, the output energy required for the excitation coil 104 is large; when the pipe diameter of the pipeline is small, the output energy required for the excitation coil 104 is small. It should be noted that if the pipeline is grounded, the output energy required for the excitation coil 104 is also large; when the pipeline is not grounded, the output energy required for the excitation coil 104 is small.

[0042] In some embodiments, the inductance parameter of the excitation coil 104 and / or the frequency of the square wave signal are determined according to the output energy of the excitation coil 104.

[0043] Taking the water transmission component 107 as a pipeline as an example, the water treatment device 100 utilizes the principle of electromagnetic induction. The signal generator 101 outputs a square wave signal or a sine wave signal and connects it to the excitation coil 104. In actual use, when the square wave frequency is fixed, the inductance parameter of the excitation coil 104 can be adjusted according to the actual pipe diameter of the water transmission component 107 so that its resonance frequency is close to the square wave frequency.

[0044] Taking the above signal generator 101 including a square wave circuit and a 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 the smallest, the power is the largest, and the output energy is the strongest. Based on this, the inductance parameter of the excitation coil 104, that is, 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 where the above signal generator 101 includes a square wave circuit and outputs a square wave signal to the excitation coil 104.

[0045] In some embodiments, as Figure 1 shown, the water treatment device 100 further includes a bracket assembly 10. The bracket assembly 10 is disposed within the water transmission member 107 and is mechanically connected to the conductive structure 106 to mount the conductive structure 106 within the water transmission member 107.

[0046] In some embodiments, referring to Figure 1 , the bracket assembly 10 includes a bracket 108 and a lining insulating layer 109. The bracket 108 includes a first support portion 1081 and a second support portion 1082 that are oppositely disposed (as Figure 3 shown). An erection area is formed between the first support portion 1081 and the second support portion 1082. The lining insulating layer 109 is disposed along the liquid transmission direction of the water transmission member 107 and wraps around the first support portion 1081 and the second support portion 1082.

[0047] Among them, the conductive structure 106 is disposed within the erection area and is mechanically connected to the first support portion 1081 and the second support portion 1082 respectively. Optionally, the connection between the conductive structure 106 and the first support portion 1081 and the second support portion 1082 can be a fixed connection or a detachable connection.

[0048] In some embodiments, the structures of the first support portion 1081 and the second support portion 1082 are the same. The first support portion 1081 includes a plurality of rods. One ends of the plurality of rods converge at a point, denoted as the convergence point. The plurality of rods are centrally symmetrically distributed with respect to the convergence point.

[0049] Among them, the conductive structure 106 is mechanically connected between the convergence points of the first support portion 1081 and the second support portion 1082. Thus, the electromagnetic field signals generated by the conductive structure 106 can act uniformly on the internal medium of the water transmission member 107 to ensure the balance of the water treatment effect.

[0050] It should be noted that to ensure the flow rate of the water to be treated in the water transmission member 107, the number of connecting rods cannot be too many to ensure that the cross-sectional area is relatively small. As an example, referring to Figure 1 , the number of rods included in the first support portion 1081 can be three. The lengths of the three rods are equal and are centrally symmetrically distributed and intersect at the symmetric center point.

[0051] In some embodiments, as Figure 3 , Figure 4 shown, the conductive structure 106 may include an electrode rod 1061, and the length direction thereof is the water flow direction. The length of the electrode rod 1061 can be adjusted according to actual needs to increase the electromagnetic action time on the flowing medium and improve the scale and corrosion inhibition effect of water treatment.

[0052] In this embodiment, referring toFigure 3 , Figure 4 , an interface 20 may be left outside the water transmission component 107, and the exciting coil 104 may pass through the interface 20 via a single wire 105 and be connected to the electrode rod 1061. One end of the electrode rod 1061 is mechanically connected to the first support portion 1081, and the other end of the electrode rod 1061 is mechanically connected to the second support portion 1082.

[0053] In some embodiments, the number of the conductive structures 106 is multiple, and the multiple conductive structures 106 are electrically connected to the second end 2 of the exciting coil 104.

[0054] Specifically, multiple conductive structures 106 can be placed in the same water transmission component 107, and the distance between adjacent two conductive structures 106 can be unrestricted, such as 1 cm, 10 cm, etc. When the exciting coil 104 adopts the structure shown in Fig. 2(a), the second end 2 of the exciting coil 104 can be connected to multiple conductive structures 106 via multiple single wires 105 respectively; when the exciting coil 104 adopts the structure shown in Fig. 2(b), the second end 2 of the exciting coil 104 can be connected to one end of multiple conductive structures 106 via multiple single wires 105 respectively, and the fourth end 4 of the exciting coil 104 is grounded.

[0055] In some embodiments, when the exciting coil 104 adopts the structure shown in Fig. 2(b), the second end 2 of the exciting coil 104 can be connected to one end of K1 conductive structures 106 via K1 single wires 105 in a one-to-one correspondence, and the fourth end 4 of the exciting coil 104 can be connected to one end of K2 conductive structures 106 via K2 single wires 105 in a one-to-one correspondence. Among them, both K1 and K2 are positive integers.

[0056] In other embodiments, the number of the conductive structures 106, the exciting coils 104 and the signal generators 101 is multiple, and the exciting coils 104 and the signal generators 101 are in one-to-one correspondence. Each signal generator 101 is electrically connected to the first end 1 and the third end 3 of the corresponding exciting coil 104, and the second end 2 of each exciting coil 104 is electrically connected to one or more conductive structures 106.

[0057] Specifically, multiple conductive structures 106 can all be placed on the outer wall of the same water transmission component 107, and the distance between adjacent two conductive structures 106 can be unrestricted, such as a distance of 1 centimeter, 10 centimeters, etc. In this embodiment, an excitation coil 104, a signal generator 101, and a conductive structure 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 in this group can be connected to one end of the conductive structure 106 in this group through a 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 in this group is connected to one end of the conductive structure 106 in this group through a single wire 105, and the fourth end 4 is grounded.

[0058] Optionally, an excitation coil 104, a signal generator 101, and multiple conductive structures 106 can also 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 in this group can be respectively connected to one end of the multiple conductive structures 106 in this group through 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 in this group is respectively connected to one end of the multiple conductive structures 106 in this group through multiple single wires 105, and the fourth end 4 is grounded, or the second end 2 of the excitation coil 104 in this group can be connected to one end of one or more conductive structures 106 in a one-to-one correspondence through one or more single wires 105, and the fourth end 4 of the excitation coil 104 can be connected to one end of one or more conductive structures 106 in a one-to-one correspondence through one or more single wires 105.

Thus, a high-frequency and high-voltage electric potential that directly acts on the medium inside the water transmission component 107 can be generated, solving the shielding energy loss of the water transmission component 107 to the magnetic field and improving the scale and fouling removal effect.
