Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a multi-dimensional electrolytic catalytic oxidation water treatment device with integrated electrocoagulation function. Background Technology

[0002] Electrochemical water treatment technologies, such as electrocoagulation and electrolytic catalytic oxidation, have been widely used in the treatment of industrial and domestic wastewater due to their advantages of high efficiency, environmental friendliness, and lack of secondary pollution. The core principle of these technologies is to utilize energized electrodes to initiate a series of electrochemical reactions in water, thereby degrading or removing pollutants. As the key site for energy conversion and reaction, the state of the electrode surface directly determines the efficiency and stability of the entire treatment system.

[0003] During electrochemical reactions, a common and unavoidable problem arises: electrode scaling and passivation. Because water contains various dissolved salts, organic matter, and intermediate products from the reaction, these substances gradually deposit and adhere to the electrode surface under the influence of an electric field, forming a dense layer of fouling. This fouling not only covers the active sites of the electrode but also significantly increases its surface resistance.

[0004] Electrode passivation caused by this fouling can directly lead to a series of serious consequences. First, it hinders the transfer of electrons between the electrode and the solution, significantly reducing current efficiency and the degradation rate of pollutants, resulting in a sharp decline in water treatment effectiveness. Second, in order to maintain the necessary treatment current, the system has to increase its operating voltage, which significantly increases the energy consumption of the equipment and raises operating costs. In the long run, continuous scaling will eventually lead to complete electrode failure.

[0005] Currently, the main method for solving the problem of electrode scaling is to perform periodic shutdown maintenance, disassembling the electrodes from the device and manually cleaning them through methods such as acid washing and mechanical scraping. This method is not only cumbersome and time-consuming, but more importantly, it interrupts the continuity of water treatment, reduces the effective operating rate of the equipment, and cannot meet the needs of modern, automated production. Therefore, developing a technical solution that can effectively maintain electrode cleanliness and activity without interrupting the treatment process has become an urgent technical challenge in this field.

[0006] Therefore, this utility model proposes a multi-dimensional electrolytic catalytic oxidation water treatment device with integrated electrocoagulation function to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in existing electrochemical water treatment devices, such as electrodes being easily passivated by dirt during operation, leading to decreased treatment efficiency, and the need for manual disassembly and cleaning during shutdown, which is complex and inefficient, this utility model aims to provide a multi-dimensional electrolytic catalytic oxidation water treatment device with integrated electrocoagulation function that has an improved structure and can effectively solve the above problems.

[0008] This utility model provides a multi-dimensional electrolytic catalytic oxidation water treatment device with integrated electrocoagulation function, including a support column, a tank fixed on the support column, and an electrolysis mechanism disposed inside the tank; the device also includes a dirt cleaning mechanism.

[0009] The dirt cleaning mechanism includes a fixed tray located at the bottom of the tank, a motor fixedly mounted on the fixed tray, a connecting shaft, a dirt cleaning disc, and ceramic beads.

[0010] Furthermore, the output shaft of the motor is rotatably connected to one end of the connecting shaft, and the other end of the connecting shaft passes through the fixed tray and is fixedly connected to the center of the dirt cleaning disc; the ceramic beads are housed in the tank and cover the dirt cleaning disc, and the distribution range of the ceramic beads in the tank covers the detachable positive and negative electrodes included in the electrolysis mechanism. The dirt cleaning disc is driven to rotate by the motor, thereby agitating the ceramic beads to physically clean the surface of the detachable positive and negative electrodes.

[0011] Preferably, the electrolysis mechanism includes a rectifier, positive and negative wires, a screw interface, an electrode fixing post, an electrode movable plate, and the detachable positive and negative electrodes; wherein, the rectifier is detachably electrically connected to the electrode fixing post through the positive and negative wires and the screw interface to provide electrical energy to the electrolysis mechanism; mechanically, the electrode fixing post can pass through the electrode movable plate and be detachably installed on the top of the tank, and the detachable positive and negative electrodes are snapped onto the electrode fixing post through slots. This structural combination facilitates the rapid disassembly, assembly, and maintenance of the core components of the entire electrolysis mechanism.

[0012] Preferably, the detachable positive and negative electrodes are electrode group structures composed of multiple electrodes arranged alternately in parallel. This structural design significantly increases the contact surface area between the electrodes and the water, thereby improving the efficiency of the electrolysis reaction.

[0013] Preferably, the anode plate in the electrode assembly structure is made of iron or aluminum to ensure that the anode can dissolve metal ions during electrolysis, which hydrolyze in water to form flocculants, thereby achieving the electrocoagulation function.

[0014] Preferably, the surface of the ceramic beads is coated with a catalyst coating, which enables them to catalytically degrade pollutants in the water while performing physical friction cleaning, thereby achieving a synergistic effect of physical cleaning and chemical catalysis.

[0015] Preferably, the upper side wall of the tank is provided with a water inlet and the lower side wall of the tank is provided with a water outlet. This top-to-bottom arrangement is conducive to forming a stable top-to-bottom processing flow field in the tank.

[0016] Preferably, the bottom of the tank is also provided with a faucet for convenient discharge of precipitated sludge and wastewater generated during electrolysis and cleaning.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of existing electrolytic water treatment devices where dirt easily adheres to the electrode surface and causes passivation, leading to a continuous decline in treatment efficiency. This is achieved by setting up a dirt cleaning mechanism consisting of a motor, a connecting shaft, a dirt cleaning disc, and ceramic beads. The motor drives the disc to agitate the ceramic beads, which continuously physically rub and collide with the electrodes. This solves the problem of complex operation and inconvenient maintenance caused by the need for manual cleaning and disassembly during operation. The device achieves the technical effect of online automatic cleaning of electrodes, maintaining electrode activity, ensuring long-term stable water treatment efficiency, and enabling continuous operation of the device.

[0018] 2. This utility model, through the adoption of a modular electrode installation structure that combines an electrode movable plate, electrode fixing column, slot, and screw interface, not only achieves rapid disassembly and replacement of electrodes, greatly simplifying the maintenance process and reducing operation and maintenance costs; more importantly, this structure provides key support for realizing multi-dimensional electrolytic catalytic functions. It allows for the convenient replacement or combination of electrodes of different materials (such as iron and aluminum anodes) and shapes according to different water qualities and treatment objectives, flexibly activating or enhancing specific treatment dimensions such as electrocoagulation and electrocatalytic oxidation; simultaneously, by ensuring that the core reaction component electrode assembly can always maintain optimal working condition, it guarantees the high efficiency and stability of the entire multi-dimensional synergistic treatment system, achieving a technical effect that closely combines structural convenience with functional feasibility.

[0019] 3. This invention cleverly integrates the electrolysis mechanism and the mechanical fouling cleaning mechanism into the same tank, constructing a highly efficient synergistic reaction space for multi-dimensional electrolytic catalytic oxidation. Within this compact structure, the electrocoagulation effect generated by a specific anode (such as iron / aluminum), the electrocatalytic oxidation effect induced by the electrode itself, and the physical grinding and multiphase catalytic oxidation effect provided by the catalyst-coated ceramic beads occur simultaneously and mutually promote each other, forming a three-dimensional synergistic treatment mechanism integrating electrochemistry, physics, and catalysis. This high degree of integration not only solves the problems of large footprint and complex piping in traditional solutions, but also achieves synergistic effects of multiple treatment paths, ultimately enhancing the treatment depth, shortening the reaction process, and achieving a high degree of unity between the device structure and function.

[0023] Example: Please refer to Figures 1 to 5 This utility model provides a multi-dimensional electrolytic catalytic oxidation water treatment device with integrated electrocoagulation function, which aims to solve the problems of existing electrolytic water treatment devices where electrodes are prone to fouling, resulting in decreased treatment efficiency and complex maintenance.

[0024] like Figure 1 As shown, the multi-dimensional electrolytic catalytic oxidation water treatment device with integrated electrocoagulation function includes a support column 7 and a tank 2 fixed on the support column 7. The tank 2 is equipped with an electrolysis mechanism 1 and a dirt cleaning mechanism 6. The upper side wall of the tank 2 is provided with a water inlet 3, the lower side wall of the tank 2 is provided with a water outlet 8, and the bottom of the tank 2 is provided with a faucet 4 for discharging wastewater and impurities. The specific structure of the dirt cleaning mechanism 6 is as follows: Figure 1 and Figure 2 As shown, the electrolysis mechanism 6 includes a fixed tray 5, a motor 601, a connecting shaft 602, a dirt cleaning disc 603, and ceramic beads 604. The fixed tray 5 is fixedly connected to the inner bottom of the tank body 2, providing a mounting base for the other components of the dirt cleaning mechanism 6. The motor 601 is fixedly mounted on the fixed tray 5, and the output shaft of the motor 601 is drivenly connected to the dirt cleaning disc 603 through the connecting shaft 602. Specifically, one end of the connecting shaft 602 is rotatably connected to the output shaft of the motor 601, and the other end passes through the fixed tray 5 and is fixedly connected to the center of the dirt cleaning disc 603. The ceramic beads 604 are contained in the tank body 2 and cover the dirt cleaning disc 603. The removable positive and negative electrodes 104 of the electrolysis mechanism 1 are disposed in the tank body 2, and the distribution range of the ceramic beads 604 in the tank body 2 covers the removable positive and negative electrodes 104, so that when the dirt cleaning disc 603 rotates, the ceramic beads 604 can be agitated to clean the surface of the removable positive and negative electrodes 104.

[0025] The structure and connection method of the electrolysis unit 1 are crucial for achieving the electrolysis reaction; please refer to them carefully. Figure 4 and Figure 5 The electrolysis mechanism 1 includes a rectifier 101, positive and negative wires 102, a screw interface 103, detachable positive and negative electrodes 104, an electrode fixing post 105, and an electrode movable plate 106. The rectifier 101 serves as the power source and is detachably electrically connected to the electrode fixing post 105 via positive and negative wires 102 and a screw interface 103. This connection via the screw interface 103 ensures the reliability of the circuit connection and the convenience of disassembly and assembly. In terms of mechanical installation structure, the electrode movable plate 106 is detachably installed at the top opening of the tank 2, and the electrode fixing post 105 can pass through the electrode movable plate 106 and be fixed, thereby suspending the entire electrode assembly inside the tank 2. The detachable positive and negative electrodes 104 themselves are snapped into the lower end of the electrode fixing post 105 via slots for easy and quick replacement. In a preferred embodiment, the detachable positive and negative electrodes 104 are electrode plate group structures composed of multiple electrode plates arranged alternately in parallel, which increases the surface area of ​​the electrolytic reaction. To achieve the electrocoagulation function, the electrode plate serving as the anode in this electrode plate group structure is made of iron or aluminum. At the same time, to further improve the treatment effect, the surface of the ceramic beads 604 is coated with a catalyst coating to provide catalytic oxidation while performing physical cleaning.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, for easy and quick disassembly and replacement of the electrodes, please refer to... Figure 4 and Figure 5 The electrode fixing post 105 can pass through the electrode movable plate 106 and be detachably installed on the top of the tank body 2. Its lower end is engaged with the detachable positive and negative electrodes 104 through a slot. This structure allows the entire electrode assembly to be lifted out simply by operating the screw interface 103 and the electrode movable plate 106 when replacing the electrode.

[0027] As another preferred embodiment, in order to effectively increase the surface area of ​​the electrolytic reaction and realize the electrocoagulation function, the detachable positive and negative electrodes 104 adopt an electrode group structure composed of multiple electrodes arranged alternately in parallel, and the electrode plate serving as the anode in the electrode group structure is made of iron or aluminum material.

[0028] As a further preferred embodiment, in order to enhance chemical degradation capabilities while performing physical cleaning, and to achieve multi-dimensional synergistic treatment, please refer to... Figure 2 The surface of the ceramic beads 604 is coated with a catalyst coating.

[0029] As a preferred implementation method to ensure smooth water flow and thorough wastewater discharge, please refer to [the following instructions] for creating a reasonable gravity flow treatment path and facilitating the removal of sediment. Figure 1 The upper side wall of the tank 2 is provided with an inlet 3 and the lower side wall of the tank 2 is provided with an outlet 8 to form a top-to-bottom treatment flow. At the same time, a faucet 4 is provided at the lowest point of the bottom of the tank 2.

[0030] The working principle is as follows: When water needs to be treated, the water flows into the tank 2 through the inlet 3. Simultaneously, the electrolysis mechanism 1 starts working, and the rectifier 101 generates electrical energy. This energy is transmitted through positive and negative wires 102, screw-type interfaces 103, and electrode fixing posts 105 to the detachable positive and negative electrodes 104, thereby initiating a continuous electrolysis reaction in the water within the tank 2. During the electrolysis process, to address the issue of decreased efficiency due to scale buildup on the electrode surface caused by the reaction, the scale cleaning mechanism 6 is activated. The motor 60, mounted on the fixed tray 5... 1. Starts to rotate, and drives the dirt cleaning disc 603 to rotate synchronously through the connecting shaft 602. The rotation of the dirt cleaning disc 603 will agitate the ceramic beads 604 scattered above it to move randomly inside the tank 2. These moving ceramic beads 604 will continuously rub, contact and collide with the surface of the detachable positive and negative electrodes 104. Through this purely physical polishing action, the dirt attached to the electrode surface is peeled off, thereby achieving online cleaning and maintaining the activity of the electrodes. The treated clean water flows out through the outlet 8.

[0031] After the treatment process is completed or when sewage needs to be discharged, the faucet 4 located at the bottom of the tank 2 can be opened to discharge the dirt peeled off the electrodes and the impurities generated during the electrolysis process along with the wastewater. When it is necessary to replace and maintain the detachable positive and negative electrodes 104, the operator first unscrews the screw interface 103 to disconnect the electrical connection between the positive and negative wires 102 and the electrode fixing post 105. Then, with the help of the electrode movable plate 106, the electrode fixing post 105 and the detachable positive and negative electrodes 104 that are snapped onto it by the slot are taken out as a whole from the top of the tank 2. Then the old detachable positive and negative electrodes 104 can be easily removed from the electrode fixing post 105 and replaced. The whole process does not require complicated tools and achieves quick maintenance.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
