Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage electrostatic water treatment and relates to an electrostatic water treatment device. Background Art

[0002] Electrostatic water treatment technology has become one of the important development directions in the field of water treatment due to its anti-scaling, sterilization and green environmental protection characteristics. However, due to technical and process limitations, the equipment's treatment efficiency is unsatisfactory, making it difficult for electrostatic water treatment equipment to be recognized by users and facing a very harsh living environment. The reason for this is that in addition to the manufacturing process problems of the equipment itself, the main reason is that during the operation of the equipment, the electrostatic field generated by the ion rod prompts the charged impurities and ions in the water to approach the field source, forming a charged layer that wraps the ion rod, resulting in a shield on the outside of the ion rod, which loses its electrostatic treatment ability for the water body.

[0003] Investigations show that the cleaning of ion rods mainly involves using ultrasonic waves or brushes to remove attachments. Although these methods can quickly remove some adsorbed particles and impurities, they have little effect on the charged adsorbed ions that mainly affect the electrostatic polarization effect, and cannot achieve the desired cleaning effect. Summary of the invention

[0004] The purpose of the present invention is to overcome the disadvantages of the prior art and to provide an electrostatic water treatment device which can remove the charged adsorbed ions on the ion rod and has a good removal effect.

[0005] To achieve the above-mentioned purpose, the electrostatic water treatment device described in the present invention comprises a high-voltage electrostatic generator, an ion rod, a cross-shaped pipe rack, a connecting arm, a low-voltage DC power supply, a cathode pipe and two electrode plates;

[0006] A high-voltage electrostatic generator is connected to an ion rod, an inlet end of a cathode pipe is welded to a cross-shaped tube frame, an end of the ion rod is fixed at the center of the cross-shaped tube frame, and electrode plates are provided on both upper and lower sides of the ion rod, wherein the electrode plates are connected to a low-voltage DC power supply, and an end of a connecting arm is inserted into the cathode pipe and connected to the electrode plate.

[0007] The high voltage electrostatic generator is connected to the ion rod via a cable and a cable connection adapter.

[0008] The cable connection adapter is fixed to the end of the ion rod, wherein a sealing gasket is arranged between the cable connection adapter and the ion rod.

[0009] The axis of the cross-shaped tube rack coincides with the axis of the cathode pipeline.

[0010] A rubber ring is fixed to the outlet end of the cathode pipe.

[0011] The connecting arm is connected by a plurality of sections of insulating pipes which are angled with each other.

[0012] Adjacent insulating pipes are connected via ball valves.

[0013] The outside of the ion rod is wrapped with a PTFE material layer.

[0014] The present invention has the following beneficial effects:

[0015] During the specific operation of the electrostatic water treatment device described in the present invention, when it is necessary to electrostatically adsorb the desorbed ion rod, the connecting arm is rotated to make the electrode plate close to the ion rod, and then the ion rod is located in the electric field formed between the two electrode plates to achieve the purpose of electrostatic adsorption of the desorbed ion rod, solve the current problem of reduced efficiency of high-voltage electrostatic water treatment, ensure the long-term, high-efficiency and stable operation of the equipment, greatly improve the application ability of the equipment, simple structure, easy operation, strong practicality, and easy to promote and apply.

Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments, and is not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concepts disclosed in the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0020] The accompanying drawings show schematic diagrams of structures according to embodiments disclosed in the present invention. These figures are not drawn to scale, and some details are magnified and some details may be omitted for the purpose of clear expression. The shapes of various regions and layers shown in the figures and the relative sizes and positional relationships therebetween are only exemplary, and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may additionally design regions / layers with different shapes, sizes, and relative positions according to actual needs.

[0021] refer to Figure 1 and Figure 2 The electrostatic water treatment device of the present invention comprises a high-voltage electrostatic generator 1, an ion rod 2, a cable connection adapter 3, a cross-shaped pipe rack 4, a connecting arm 6, a low-voltage DC power supply 7, a cathode pipe 8, a rubber ring 9 and two electrode plates 5;

[0022] The high-voltage electrostatic generator 1 is connected to the ion rod 2 via a cable and a cable connection adapter 3, wherein the cable connection adapter 3 is fixed to the end of the ion rod 2, wherein a sealing gasket is provided between the cable connection adapter 3 and the ion rod 2;

[0023] The inlet end of the cathode pipe 8 is welded to the cross-shaped pipe rack 4, and a rubber ring 9 is fixed to the outlet end of the cathode pipe 8. The cable passes through the cross-shaped pipe rack 4, and the axis of the cross-shaped pipe rack 4 coincides with the axis of the cathode pipe 8. The end of the ion rod 2 is fixed at the center of the cross-shaped pipe rack 4. Electrode plates 5 are arranged on the upper and lower sides of the ion rod 2, wherein the electrode plates 5 are connected to the low-voltage DC power supply 7, and the end of the connecting arm 6 is inserted into the cathode pipe 8 and connected to the electrode plate 5, wherein the connecting arm 6 is connected by several sections of insulating pipes that are angled with each other, wherein adjacent insulating pipes are connected by a spherical valve to ensure the rotation of the connecting arm 6.

[0024] In addition, it should be noted that the outside of the ion rod 2 is insulated and sealed by a PTFE material layer. During operation, the connecting arm 6 is rotated to make the electrode plate 5 close to or away from the ion rod 2. When the electrostatic adsorption of the ion rod 2 needs to be desorbed, the connecting arm 6 is rotated to horizontally move the electrode plate 5 so that the electrode plate 5 is close to the ion rod 2, that is, the distance between the two electrode plates 5 is 2-3 times the diameter of the ion rod 2, so that the ion rod 2 is located in the electric field formed between the two electrode plates 5 to achieve the purpose of electrostatic adsorption of the desorption ion rod 2. After the power is turned on and the desorption is preset for a time, the connecting arm 6 is rotated to make the electrode plate 5 away from the ion rod 2 and move toward the inner wall direction of the cathode pipe 8 to reduce the distribution of the electrostatic field of the ion rod 2 itself, without affecting the electrostatic field distribution of the original high-voltage electrostatic water treatment device and its anti-scaling and sterilization effect, and the structure is relatively simple.

[0025] The present invention wraps a rubber ring 9 at the outlet end of the cathode pipe 8 to contact the sealing pool wall, thereby achieving a full-flow water treatment effect of the equipment and increasing the universality of the equipment.

[0026] Finally, it should be noted that the present invention adopts an electrochemical method to remove impurities and ions, and utilizes the principle of capacitive deionization to place the ion rod 2 in a movable low-voltage DC electric field, and complete the desorption of charged particles on the ion rod 2 through the action of the electric field force.
