Description

Technical Field

[0001] This utility model relates to the field of three-dimensional electrolysis technology, and in particular to a three-dimensional electrolysis device. Background Technology

[0002] Three-dimensional electrolysis refers to the use of particle electrodes to form a voltage difference under the condition of an external DC power supply. On the surface of the particle electrode, an oxidation-reduction reaction occurs, generating a large number of hydroxyl radicals. Organic matter undergoes ring opening and chain breaking, transforming into small molecule organic matter or CO2 and H2O.

[0003] Existing technologies often suffer from the following drawbacks: low processing efficiency, particle electrode caking, difficulty in replacing electrode plates, requiring manual removal of the particle electrodes before replacement, and then replacement and replacement of the particle electrodes, which typically requires a 1-2 day downtime.

[0004] Therefore, this invention provides a three-dimensional electrolysis device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as low processing efficiency and efficiency degradation, by proposing a three-dimensional electrolysis device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a three-dimensional electrolysis device, comprising a main unit, wherein the upper part of the main unit is provided with two water outlets and two circulation ports, and the lower part is provided with two water inlets, two aeration / backwash ports, one vent port, and a reserved port. The diameter of the water outlet pipes is DN50, the diameter of the circulation ports is DN25, the diameter of the water inlets is DN20, the diameter of the aeration / backwash ports is DN50, the diameter of the vent port is DN20, and the material of the reserved port is PP material. A blower is also provided on the outside of the main unit. A positive terminal and a negative terminal are provided on the top side of the main unit. A DC power supply is electrically installed at the other end of the positive terminal and the negative terminal. A top inclined brace is provided on the top side of the main unit.

[0007] Preferably, the main device is surrounded by four reinforcing steel hoops, each measuring 40mm*80mm, made of PP material on the outside and welded together to form a ring of steel on the inside. There is a lifting lug on each of the two sides above the main device, and the lifting lug is 12mm thick.

[0008] Preferably, the main device is provided with a grid electrode slot, a grid support plate and an electrode plate inside. The grid electrode slot is 10mm thick and the internal spacing of the grid electrode slot is 21mm. The grid support plate has a 6mm hole and a thickness of 20mm. The electrode plate is 5mm thick and the electrode plate spacing is 100mm. The electrode plate spacing can be adjusted to 200mm, 300mm, 400mm, etc., according to different sewage conductivity conditions.

[0009] Preferably, non-standard customized particle electrodes are provided above the grid support plate and between adjacent grid electrode slots in the main device. The filling height is 1.2m and the diameter of the non-standard customized particle electrodes is between 8 and 15mm. The particle electrodes cannot pass through the pores of the grid plate. Through the pressure difference, the sewage flows through the pores inside the particle electrodes and then through the pores of the grid plate to flow through the adjacent area, making full use of the specific surface area of ​​the particle electrodes.

[0010] Preferably, the bottom of the grid support plate is provided with support columns for support, and the bottom space is used to arrange the pipeline. There are thirty support columns, which are made of PP and have a size of φ20. They are connected to the bottom of the grid support plate and the trough by welding.

[0011] Preferably, the main device has several backwash / aeration pipes evenly arranged inside, and two main air inlets.

[0012] Preferably, the main device is provided with an F-shaped water inlet pipe with two main inlets. The backwash / aeration pipe and the water inlet pipe are both perforated aeration pipes with a perforation diameter of 6-8 mm. The perforations are opened at a 45° downward angle on both sides, and the distance between adjacent holes is 160 mm.

[0013] In summary:

[0014] 1. In this utility model, the traditional technical solution sets pebbles at the bottom, which is easy to clog; generally, it is not equipped with a circulation system, and the flow rate of the circulation system is only 2-3 times faster than the inlet water, with a water flow rate of about 3m / s. Moreover, the inlet water passes through the pebbles first. Due to the resistance of the pebbles, the flushing effect on the particle electrode (10) is negligible; the electrode plate groove is only a short-side groove, and the electrode plate is in direct contact with the particle electrode. The direct contact between the electrode plate and the particle electrode produces other reactions, which accelerates the consumption of the particle electrode and easily causes particle electrode caking; because the particle electrode is in direct contact with the electrode plate, the particle electrode exerts greater pressure and frictional resistance on the electrode plate, and cannot be directly extracted. Even if it can be extracted, it is not possible to directly replace the electrode plate. It is necessary to drain the pool water, empty the particle electrode, and then replace the electrode plate. Then, the particle electrodes are refilled. This technical solution does not have pebbles at the bottom, and the elevated structure makes it less prone to clogging. It is equipped with a circulation system with a water flow rate of about 5-7 m / s. The circulating water directly washes the particle electrodes, greatly protecting the surface of the particle electrodes. The electrode plate groove is a whole grid plate, which separates the particle electrodes from the electrode plates, but does not affect the water flow. Because the particle electrodes are separated from the electrode plates, the force of the particle electrodes acts on the grid plate groove. The electrode plates can be easily pulled out and inserted without draining the pool water or hollowing out the particle electrodes. Compared with traditional technical solutions, this technical solution has a non-standard customized spherical particle electrode and grid electrode plate groove spatial design structure, an elevated bottom, no pebbles, and an added high-speed circulation flushing system to wash away the deposits on the surface of the particle electrodes.

Detailed Implementation

[0018] Reference Figure 1-2 As shown, this utility model provides a technical solution: a three-dimensional electrolysis device, including a main unit.

[0019] The following is a detailed explanation of its overall setup and function.

[0020] In this implementation plan: the upper part of the main device is provided with two water outlets 1 and two circulation ports 2, and the lower part is provided with two water inlets 6, two aeration / backwash ports 7, one drain port 8, and a reserved port. The diameter of the water outlet 1 is DN50, the diameter of the circulation port 2 is DN25, the diameter of the water inlet 6 is DN20, the diameter of the aeration / backwash port 7 is DN50, the diameter of the drain port 8 is DN20, and the reserved port is made of PP material. A blower 9 is also provided on the outside of the main device. The top side of the main device is provided with a positive terminal 16 and a negative terminal 17. The other end of the positive terminal 16 and the negative terminal 17 are electrically connected to a DC power supply 15. The top side of the main device is provided with a top diagonal brace 4.

[0021] Specifically, the main unit is surrounded by four reinforcing steel hoops 5, each measuring 40mm*80mm. The outer part is made of PP material and the inner part is a welded steel ring. There is a lifting lug 3 on each side above the main unit, and the lifting lug 3 is 12mm thick.

[0022] The main device is equipped with a grid plate groove 11, a grid support plate 12, and an electrode plate 14. The grid plate groove 11 is 10mm thick and the internal spacing is 21mm. The grid support plate 12 has a 6mm hole and a thickness of 20mm. The electrode plate 14 is 5mm thick and the spacing between the plates is 100mm. The spacing between the plates can be adjusted to 200mm, 300mm, 400mm, etc., depending on the conductivity of different wastewater.

[0023] Non-standard customized particle electrodes 10 are installed above the grid support plate 12 and between adjacent grid electrode slots 11 in the main unit. The filling height is 1.2m, and the diameter of the non-standard customized particle electrodes 10 is between 8 and 15mm. The particle electrodes 10 cannot pass through the pores of the grid plate. Through pressure difference, sewage flows through the internal pores of the particle electrodes 10 and then through the pores of the grid plate to flow through the adjacent area, making full use of the specific surface area of ​​the particle electrodes 10. Support columns 13 are provided at the bottom of the grid support plate 12 to support the pipeline. There are thirty support columns 13, which are made of PP and have a size of φ20. They are connected to the bottom of the grid support plate 12 and the tank body by welding.

[0024] The main unit has several backwash / aeration pipes evenly arranged inside, and two main air inlets. The main unit also has an F-shaped water inlet pipe with two main inlets. Both the backwash / aeration pipe and the water inlet pipe are perforated aeration pipes with a perforation diameter of 6-8 mm. The perforations are opened at a 45° downward angle on both sides, and the distance between adjacent holes is 160 mm.

[0025] The working principle involves a main unit made of PP material, with an internal structure of welded perforated PP plates. Multiple reinforcing steel hoops reinforce the tank. The unit also includes custom-designed non-standard particle electrodes 10. These electrodes have an iron-to-carbon ratio close to 1:1 and are formed by high-temperature sintering with the addition of metal catalysts and activators. They are then machined into spherical shapes in a mold workshop. This spherical structure makes it difficult for the produced particles to form a thin film on their surface. High-flow-rate circulating water washes over the particle electrodes 10, ensuring their surface remains in contact with wastewater and preventing the pores from being covered by products and impurities. The device is suitable for various types of electrode plates 14 with thicknesses ranging from 1 to 15 mm. Because a mesh plate separates the particle electrodes 10 from the electrode plates 14, replacing the electrode plates does not require removing the particle electrodes 10. The plates can be easily replaced using a gantry crane and rollers, simplifying maintenance and eliminating the need for downtime maintenance common in the industry. This invention addresses the problem by significantly reducing maintenance costs and improving production efficiency. Simultaneously, the particle electrode 10 is separated from the electrode plate 14, preventing direct contact between the particle electrode 10 and the electrode plate 14, thus avoiding unwanted reactions and caking. This promotes the particle electrode 10 to react to generate hydroxyl radicals to the greatest extent possible. The bottom of this application does not contain pebbles; the elevated structure prevents clogging. Equipped with a circulation system, the water flow rate is approximately 5-7 m / s, and the circulating water directly washes the particle electrode 10, greatly protecting its surface and allowing wastewater to enter its pores. The electrode plate groove is a single mesh plate, separating the particle electrode 10 from the electrode plate 14 without affecting water flow. Because the particle electrode 10 is separated from the electrode plate 14, the force of the particle electrode 10 acts on the mesh groove plate, allowing the electrode plate 14 to be easily removed and inserted without draining the pool water or hollowing out the particle electrode 10.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
