Electrocatalytic oxidation reactor

Abstract

The invention discloses an electrocatalytic oxidation reactor. The electrocatalytic oxidation reactor comprises reaction chambers, wherein electrode groups are arranged in the reaction chambers; at least one electrode group is arranged, adjacent electrode groups are directly partitioned by arranging a partition board in the reaction chambers when more than two electrode groups are arranged in the same reaction chamber, and water flow at the bottom of the partition board is in a through state; each electrode group comprises two symmetrical support plates which are arranged in parallel; an electrode is arranged between the support plates; the electrode comprises a group of anode plates and a group of cathode plates which are sequentially arranged in a staggered manner; the upper ends and the lower ends of the support plates are respectively provided with two groups of symmetrical comb teeth fixed buckles; the left ends and the right ends of the support plates are respectively provided with three groups of symmetrical comb teeth fixed buckles; the comb teeth buckles and the support plates are connected and fixed by bolts. The electrocatalytic oxidation reactor disclosed by the invention is high in efficiency, single electrode plate can be separately cleaned and replaced after the electrocatalytic oxidation reactor is used for a period of time, a space between polar plates is fixed, a treatment effect is good, energy consumption is stable and reliable, and the running cost is low.

Description

technical field [0001] The invention relates to a sewage treatment equipment accessory, in particular to an electrocatalytic oxidation reactor. Background technique [0002] Existing electrode reactor designs generally adopt two methods: [0003] Method 1: The top of each electrode plate is directly welded to the electric cable. During the sewage treatment process, the connection between the cable and the electrode plate is extremely prone to corrosion and leakage. At the same time, there is no fixed interval between the electrode plates. After the temperature of the electrode plates rises and deforms during the reaction process, the distance between the electrode plates is not fixed, causing the electrode plates to touch each other and short flow occurs. At the same time, the unfixed distance affects the treatment effect and increases System power consumption. Moreover, the electrodes are fixedly connected. When maintenance and cleaning are required, they cannot be taken ...

AI Technical Summary

Problems solved by technology

This connection method can solve the cable corrosion problem in method 1, but the welding operation cost is high, and professional welders must be welded, and the thermal deformation during the welding process leads to inaccurate control of the distance between the electrode plates, resulting in ineffective treatment. stable, increased energy consumption

[0005] In addition, due to the fixed connection between the electrode sheets by welding, when a single sheet needs to be cleaned or replaced, it cannot be replaced by a single sheet, and the entire group must be taken out for maintenance and replacement, and the replacement frequency and cost are high.

At the same time, due to the weight limit of single-person operation, after the number of electrodes in each group increases, it cannot be operated by a single person. Other lifting tools must be assisted to lift the entire motor group out of the reactor, which requires a larger operation and maintenance reserve. space, inconvenient to maintain
