Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a symmetrically laid electrode multi-source electrocatalytic reaction device. Background Art

[0002] Due to the rapid development of emerging industries, the scale of industrial production is constantly expanding, and the amount of industrial wastewater discharged is increasing. For wastewater with complex components, high pollution load and low biochemical performance, traditional physical and chemical methods, biochemical methods and other processes are difficult to efficiently remove highly toxic and difficult to degrade organic matter. The research and development of industrial wastewater treatment technology is of great significance to the development of the environmental protection industry.

[0003] Electrocatalytic oxidation technology has the advantages of high efficiency, no secondary pollution, and low energy consumption, and has gradually become a research hotspot in the field of industrial wastewater treatment. Its basic principle is to apply voltage to the electrode to cause direct or indirect oxidation reaction of organic matter in the wastewater, thereby achieving the degradation of organic matter. Direct oxidation refers to the oxidation of organic matter in the wastewater to small, easily degradable substances on the anode surface, while indirect oxidation is through the active species generated on the electrode, such as ·OH, O2 - Etc., to remove or mineralize substances in wastewater.

[0004] Since the cathode plate and the anode plate will be worn out and impurities will be attached during use, the current electrocatalytic device has difficulty in operating when replacing the electrode plate. Patent CN 214004133U discloses a water treatment electrode plate. By improving the electrode plate, the problem of complex replacement of the electrode plate and short circuit of the anode and cathode plates is solved. However, the patent adopts a horizontal electrocatalytic device, which has the disadvantages of large floor space and poor mass transfer effect. Therefore, the problem of replacing the electrode plate of the vertical electrocatalytic device still needs to be solved. In addition, the connection between the electrode plate and the reaction tank is prone to short circuit due to water seepage, and this component needs to be optimized to ensure the good operation of the electrocatalytic device. Utility Model Content

[0005] In view of the problems and shortcomings of existing electrocatalytic devices, the utility model proposes a multi-source electrocatalytic reaction device with symmetrically laid electrodes to solve the problems of inconvenient replacement of electrode plates and easy short circuit between electrode plates in vertical electrocatalytic equipment described in the above background technology. The following technical solutions are adopted:

[0006] A multi-source electrocatalytic reaction device with symmetrically laid electrodes comprises a vertical reaction tube, wherein the vertical reaction tube is composed of two or more reaction tube units connected vertically in sequence, and a top cover is installed on the top of the vertical reaction tube; the vertical reaction tube is provided with a water inlet and a water outlet;

[0007] More than three groups of electrode plates are arranged inside each reaction cylinder unit. Each group of electrode plates consists of an anode plate and a cathode plate. The anode plate and the cathode plate of each group of electrode plates are arranged horizontally and arranged in parallel in the vertical direction. Each group of electrode plates is installed in a symmetrical flat manner around the center of the reaction cylinder unit, and a manhole is provided on the side of each reaction cylinder unit.

[0008] Preferably, a sealing waterproof plate made of insulating material is installed on the side of the reaction cylinder unit, and the anode plate and the cathode plate are fixed to the reaction cylinder unit by joint copper bolts arranged on the outside of the sealing waterproof plate.

[0009] Preferably, the joint copper bolts fixing the same anode plate or cathode plate are connected by a copper busbar, and the joint copper bolts fixing different anode plates or cathode plates are connected by wires, the anode plate is connected to the positive pole of the power supply through the corresponding joint copper bolts, and the cathode plate is connected to the negative pole of the power supply through the corresponding joint copper bolts.

[0012] Preferably, an exhaust port and an aeration port are provided at the lower part of the side surface of the lowest reaction cylinder unit, wherein the aeration port is connected to a perforated aeration pipe inside the vertical reaction cylinder.

[0013] The beneficial effects of the utility model are:

A manhole is provided on the outside of the reaction cylinder unit, and multiple groups of electrode plates are symmetrically laid flat around the center of the reaction cylinder.
