With the development of the power industry, electrochemical technology has gradually been applied to the field of water treatment, with the advantages of high efficiency and pollution-free. However, traditional electrochemical devices mostly use a set of yin-yang flat electrodes, with a small reaction area, bubbles cannot be released in time on the surface of the plate, thus affecting the electrode reaction rate and the mass transfer problem cannot be well solved; or a composite form of multiple cathode plates is used to deposit the outer plate first, and the scale on the outer layer and the hydroxide ions on the inner layer are used to accelerate the deposition of scale, which speeds up the scale deposition rate, but still does not solve the problem of bubble escape.

[0021] The present invention will be further described below in conjunction with the accompanying drawings:

[0022] The present invention arranges magnets on both sides of the pole plate and utilizes the local electric field distortion caused by bubbles on the pole plate to generate an angle between the electric field and the magnetic field of the magnet, thereby inducing Lorentz force, thereby causing microscopic magnetic convection of the bubbles, accelerating the detachment of the bubbles from the pole plate, and allowing the bubbles to be released and escaped in time.

[0023] The electrochemical water treatment device with an external magnetic field according to the embodiment of the present invention is as follows: Figure 1As shown, it includes an anode and a cathode; the anode of the device is provided with an anode plate 1, and magnets 3 are provided on both sides of the anode plate 1; the cathode of the device is provided with a cathode plate 2, and magnets 3 are provided on both sides of the cathode plate 2, that is, at least four magnets. Among them, the anode plate 1 and the cathode plate 2 can be made of conductive metal materials, and their shape can be mesh, such as ordinary titanium mesh, such as Figure 2 As shown, a terminal 8 is provided on the top of the pole plate, and the power supply is connected to the pole plate through the terminal 8. The magnet can be a permanent magnet, and the Lorentz force generated by the magnetic field of the magnet 3 and the electric field caused by the bubbles causes microscopic magnetic convection of the bubbles, accelerates the detachment of the bubbles from the pole plate, and allows the bubbles to be released and escaped in time. A mesh membrane 5 for receiving scale can also be provided at the bottom of the anode plate 1 and the cathode plate 2, which only allows gas and liquid to pass through, thereby receiving scale and facilitating later cleaning.

[0024] Furthermore, the area of ​​the magnet 3 is greater than or equal to the area of ​​the pole plate, so that every position of the pole plate can be covered by the magnetic field, and every position of the pole plate can be affected by the magnetic field, thereby achieving the best effect.

[0025] Furthermore, if Figure 2 As shown, the cathode of the device is provided with multiple cathode plates 2, and there are gaps between the cathode plates 2 for bubbles to pass through. After power is turned on, multiple plates work simultaneously, which greatly improves the efficiency of water treatment and reduces energy consumption; the plate is in a mesh shape, with mesh openings on the surface and gaps between them for bubbles to pass through, which is convenient for gas to escape. The number of cathode plates is 5, and the effect is best at this time. When the terminal 8 connected to the power supply is installed on the middlemost plate, in order to ensure the balance of the cathode, the number of cathode plates is preferably odd.

[0026] Furthermore, if Figure 3 As shown, the device also includes a connecting rod 6, on which a slot 7 for installing a pole plate is provided, and the width of the slot 7 is the same as the thickness of the pole plate, and the pole plate is arranged in the slot 7 of the connecting rod. In particular, when there are multiple cathode plates, multiple cathode plates 2 can be connected by connecting rods 6, and the number of connecting rods is not limited. Preferably, the material of the connecting rod is a magnetic conductive material, which plays the role of connection, fixation, and conduction: the magnets 3 on both sides of the pole plate can be connected by the magnetic connection of the connecting rod 6, and the magnets 3 are connected to the pole plates on the connecting rod 6 by connecting to the connecting rod 6, so that the device as a whole is convenient to disassemble, install and clean; at the same time, the pole plates arranged in the slot 7 of the same connecting rod can be conductive through the connecting rod, that is, a terminal 8 for connecting a power supply can be arranged on one of the pole plates. In addition, the part where the connecting rod contacts the magnet 3 is coated with an insulating material to prevent the magnet from generating an electric field and interfering with the electrolysis.

[0027] Furthermore, the device also includes a telescopic rod 4, which may have a scale, and the positive and negative plates are connected by the telescopic rod 4, so that the distance between the positive and negative plates can be adjusted. At this time, the device as a whole includes: magnet 3, anode plate 1, magnet 3, telescopic rod 4, magnet 3, single cathode plate or multiple cathode plates, magnet 3; if a connecting rod 6 is used to connect the magnets 3 on both sides of the plate, when the plate is set on the connecting rod 6, the telescopic rod 4 can be connected to the two magnets 3 in the middle, so as to adjust the distance between the positive and negative plates.

[0028] When the above device is working, the positive and negative plates are connected to the power supply through the top terminals and then put into water, and the power is turned on to start working; bubbles and scale will form on the surface of the plates during work, and the bubbles will quickly detach from the plates under the action of the magnetic field; the scale can be taken up by the mesh membrane at the bottom of the plates; after stopping working, the magnet, the connecting rod and the telescopic rod are connected by magnetic force, and the plates and the connecting rod are connected by a slot, so the whole is easy to disassemble and clean.

[0029] It will be easily understood by those skilled in the art that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
