Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an anode box and electrochemical treatment equipment. Background Technology

[0002] Electrochemical water treatment technology utilizes electrochemical reactions (including oxidation, reduction, flocculation, and flotation) that occur in wastewater to achieve the degradation, separation, or transformation of pollutants.

[0003] In electrochemical treatment, oxidation reactions typically occur at the anode (such as generating ·OH radicals, strong oxidizing substances like Cl2 and O2, or directly oxidizing contaminants). Simultaneously, the anode material (such as soluble anodes like iron or aluminum) may dissolve to generate metal ions (such as Fe). 2+ Al 3+ These substances are key to the degradation of pollutants or the formation of flocs. If the anode is directly exposed to wastewater, its oxidation products may be rapidly consumed by reducing substances in the wastewater (such as organic matter and sulfides), or react with reducing substances generated at the cathode (such as H2 and OH). - A reverse reaction occurs, reducing processing efficiency.

[0004] Some water treatment equipment on the market directly immerses the anode and cathode plates in wastewater and then applies electricity for electrochemical treatment. This design may result in low efficiency in electrochemical water treatment.

[0005] For example, the electrochemical wastewater treatment device disclosed in Chinese patent application number CN201821058947.8 includes a treatment tank, a power supply, an anode plate, and a cathode plate, wherein the anode plate and cathode plate are disposed within the treatment tank. This design involves directly immersing the cathode plate and anode plate in the wastewater, which may result in low water treatment efficiency.

[0006] For example, CN202221014020.0 discloses an automatic descaling electrochemical water treatment device, which also involves directly immersing the cathode plate and anode plate in sewage, potentially leading to low water treatment efficiency. Utility Model Content

The lateral distance S2 between the through holes is equal to S1, thus resulting in a large number of through holes and high electrochemical reaction efficiency.

[0046] Preferably, the width W1 of the first socket 31 is greater than the width W2 of the first channel 32; the width W3 of the second socket 34 is equal to the width W4 of the second channel 35.

[0048] Example 2

[0049] Example 2 includes the anode box from Example 1; the identical parts will not be described again. Please refer to... Figure 9 The illustrated electrochemical treatment device includes the aforementioned anode boxes, with several anode boxes spaced apart within a wastewater tank 40. Cathode plates 41 are positioned between the anode boxes. A first inlet faces the anode boxes, and a second inlet faces the wastewater tank 40. A scraper device 42 is mounted on the top of the wastewater tank 40. This scraper device includes a liftable scraper frame 43 and scrapers 42 mounted on the scraper frame 43. The scrapers 42 remove dirt from the cathode plates 41. The wastewater tank 40 is made of stainless steel. An installation groove is formed between the limiting plates on the inner wall of the wastewater tank 40, allowing the anode boxes to be directly inserted into the groove for convenience. The scraper frame 43 is driven up and down by a cylinder or hydraulic cylinder. When the scraper frame 43 moves downwards, the scrapers 42 remove dirt from the cathode plates 41. The wastewater tank 40 has dual inlets, allowing wastewater in the anode boxes to overflow from an overflow tank, ensuring the water level in the anode boxes remains at a normal position.
