Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment, in particular to an electrochemical reactor with spiral sheet electrodes. Background Art
[0002] Wastewater treatment has always been a research hotspot. The electrochemical method for treating sewage has the advantages of not needing to add oxidants, flocculants and other chemicals, small equipment size, small footprint, simple and flexible operation, etc., and is called a green treatment process.
[0003] At present, most electrochemical reactors in the field of water treatment are based on flat-plate electrodes because they are easy to process and install. However, flat-plate electrodes have poor mass transfer effects and are less likely to collide with organic pollutants. In order to increase the probability of collision, the flow rate of water on the electrode surface is generally increased by increasing the electrode area or adding baffles. However, there are few cases of direct improvement of the electrode structure. Utility Model Content
[0004] In view of the above problems existing in the existing electrochemical reactor, the present utility model is proposed.
[0005] Therefore, the purpose of the utility model is to provide an electrochemical reactor with spiral sheet electrodes, which solves the problem that the existing electrochemical reactors generally increase the electrode area or add baffles to enhance the flow rate of water on the electrode surface, but there are few cases of direct improvement of the electrode structure.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] An electrochemical reactor with a spiral sheet electrode comprises a spiral sheet anode, a first flange is welded to the upper end of the spiral sheet anode, an anode terminal is welded to the outside of the first flange, a spiral sheet cathode is arranged below the spiral sheet anode, a second flange is welded to the lower end of the spiral sheet cathode, and a cathode terminal is welded to the outside of the second flange.
[0008] Preferably, the outer surfaces of the spiral sheet-shaped anode and the spiral sheet-shaped cathode are jointly provided with a tubular shell.
[0009] Preferably, a water outlet is provided on one side of the upper end of the tubular shell.
[0010] Preferably, a water inlet is provided on one side of the lower end of the tubular housing.
[0011] Preferably, a water sealing line is provided on one side of the first flange and the second flange which are close to each other.
[0012] Preferably, an insulating gasket is provided between the first flange and the second flange.
[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0014] 1. The utility model uses spiral-plate anode and cathode to maximize the use of electrode sheets in the tubular space. At the same time, the spiral-plate anode and cathode can also realize the directional movement of water flow, without the need to add additional structures such as baffles to change the direction of water flow. Moreover, this method can be directly connected to the existing pipeline, which is convenient to install and does not require additional site installation.
[0015] 2. The utility model can play a protective role through the tubular shell. At the same time, the tubular shell adopts a standard pipe diameter, which is convenient for later connection with conventional pipelines. At the same time, the spiral sheet anode and the spiral sheet cathode have the same structure, and the spiral direction is consistent with the water inlet direction. BRIEF DESCRIPTION OF THE DRAWINGS
