Description

TECHNICAL FIELD

[0001] The utility model relates to an electrocatalytic oxidation device, more specifically, a novel electrocatalytic oxidation device with a power supply and electrode plate connection mode. TECHNICAL BACKGROUND

[0002] In the field of wastewater treatment, electrocatalytic oxidation technology stands out due to its high efficiency and environmental protection characteristics, which can significantly degrade organic matter, reduce total nitrogen content, and effectively break the coordination bond of heavy metal complex ions, achieving effective separation of complex heavy metals. Its importance is self-evident. Currently, the power supply selection for electrocatalytic oxidation technology is gradually shifting from traditional low-voltage power frequency power supply to more compact and efficient energy-saving high-frequency power supply. The reason is that the power frequency power supply is difficult to meet the needs of modern wastewater treatment due to its large size and limitations in output current and voltage. In the process of wastewater electrocatalytic oxidation treatment, wastewater is placed in an insulating container, and the anode plate and cathode plate, which do not contact each other, are connected to the anode and cathode of the power supply, respectively, forming an electronic circuit and triggering a chemical reaction. Traditionally, the power supply and electrode plate are connected by soft wires with copper noses at both ends. Although this connection method is convenient and easy to disassemble, it has problems such as easy omission of soldering after copper nose compression, loose connection leading to wire heating, and other issues. In addition, the connection interface resistance between different metal materials may also cause heating and virtual connection, and in severe cases, it may even cause electrochemical corrosion and spark flashover. To ensure long-term stable reaction effect, the power supply output current and voltage need to be gradually increased, and if the equipment is not maintained in time, it may lead to an increase in failure rate and waste of electrical energy.

[0003] Although the existing power supply and electrode plate connection method is relatively mature, it still has many of the above-mentioned deficiencies. In view of this, this paper proposes a connection method for the power supply and electrode plate in an electrocatalytic oxidation device. This device reduces the number of connection points in the circuit, increases the bite force and number of connection point bolts, and prevents corrosion and oxidation of the conductive carrier material, reducing electrical failure rate, saving energy, and making wastewater electrocatalytic oxidation treatment continuously reach the best state, extending the decay time period to the maximum, and prolonging the bolt fastening maintenance period between connection points. UTILITY MODEL CONTENT

[0004] To solve the above technical problems, the utility model provides a novel electrocatalytic oxidation device with a power supply and electrode plate connection mode, which adopts the following technical solutions:

[0005] The utility model relates to a new type of power supply and polar plate connection mode's electrocatalytic oxidation device, its characterized in being including electrocatalytic oxidation reaction groove, power supply, cathode plate, anode plate, cathode main copper row, anode main copper row, cathode turning copper row, anode turning copper row, cathode connection copper row, anode connection copper row, first connecting bolt and second connecting bolt, the power supply includes power supply anode, power supply cathode, the anode plate is connected to power supply anode by anode turning copper row, anode main copper row, anode connection copper row in proper order, the cathode plate is connected to power supply cathode by cathode turning copper row, cathode main copper row, cathode connection copper row in proper order, the top of electrocatalytic oxidation reaction groove is equipped with water inlet, water outlet.

[0006] Further, the cathode connection copper row connects the power supply cathode and the cathode main copper row, the cathode main copper row connects a plurality of cathode turning copper rows and cathode connection copper rows, the cathode turning copper row connects the cathode main copper row and the cathode plate; the anode connection copper row connects the power supply anode and the anode main copper row, the anode main copper row connects a plurality of anode turning copper rows and anode connection copper rows, and the anode turning copper row connects the anode main copper row and the anode plate.

[0007] Further, the first connecting bolt connects the anode main copper row and the anode turning copper row, and the first connecting bolt connects the cathode main copper row and the cathode turning copper row; the second connecting bolt connects the anode plate and the anode turning copper row, and the second connecting bolt connects the cathode plate and the cathode turning copper row; the first connecting bolt and the second connecting bolt are fastened by means of a retreat-preventing bolt, and the contact surface is coated with conductive paste; the first connecting bolt and the second connecting bolt are made of a metal material with high strength and resistance to electrochemical corrosion.

[0008] Further, the electrocatalytic oxidation reaction groove is made of PP or tetrafluoroethylene that has insulation properties.

[0009] Further, the cathode turning copper row and the anode turning copper row can both realize a 90° turning function of the connection surface, thereby reducing the fastening points of the copper rows.

[0010] Further, the electrocatalytic oxidation reaction groove is made of PP or tetrafluoroethylene that has insulation properties.

[0011] Further, the water inlet is located 100-150 mm below the top end of the electrocatalytic oxidation reaction groove, and the water outlet is located 150-200 mm below the top end of the electrocatalytic oxidation reaction groove.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] (1) The utility model provides an innovative power supply and copper bar connecting mode, this mode prolongs maintenance cycle significantly, reduces manpower cost investment, effectively reduces failure rate, and realizes the saving of electric energy.

[0014] (2) Compared with the cable, the copper bar has more excellent heat dissipation performance, can more effectively release the heat generated in the current transmission process. The large air contact area makes the cooling time greatly shorten.

[0015] (3) Under the same cross-sectional area, the cost of copper bar connection is more low compared with cable connection. In addition, the vertically arranged copper bar can improve about 1 / 3 in current transmission capacity, thereby significantly reducing the material cost investment.

[0016] (4) The cable connection needs additional copper nose compression, increases the connection point, which is not conducive to the smooth delivery of current. The copper bar connection has fewer connection points, and the connection adopts two or more bolts, and is equipped with a stop bolt, which not only reduces the loosening risk, but also prolongs the loosening period.

[0017] (5) The hard connection mode of copper bar effectively avoids the deformation and damage of the wire soft connection that may occur during disassembly, thereby ensuring the stability of the current-carrying capacity and avoiding the influence of the wound on the current-carrying effect.

[0018] (6) By adopting the turning copper bar, we realize 90° turning, avoid the increase of additional connection points, thereby reducing the potential failure point, improving the stability and reliability of the system. BRIEF DESCRIPTION OF DRAWINGS
