Description

Technical Field

[0001] This utility model relates to the field of electrolysis equipment technology, and in particular to an electrolysis device. Background Technology

[0002] Electrolysis devices can be effectively used for the treatment of industrial and domestic wastewater, and are particularly suitable for the electrolytic degradation of pollutants containing organic matter, heavy metal ions, ammonia nitrogen, and other contaminants. Existing electrolysis devices have the following technical problems:

[0003] 1. Insufficient electrode structural strength: Flat plate electrodes are prone to deformation under the impact of fluid flow, resulting in changes in electrode spacing and bending, which affects the uniformity of electrolysis reaction.

[0004] 2. Low reaction area utilization: Traditional planar electrodes have limited contact area with the fluid and lack effective segmentation of the reaction area, resulting in uneven local current density.

[0005] 3. Poor sealing reliability: The interface between the electrode and the cavity is prone to leakage due to pressure changes, which affects the safety and service life of the equipment.

[0006] To address these issues, existing technologies have attempted to increase electrode thickness or incorporate independent support structures. However, the former leads to increased material costs and reduced reaction area, while the latter suffers from structural complexity and inconvenient installation. Therefore, there is an urgent need for an electrolysis device that can both enhance electrode structural strength and optimize the utilization of reaction space. Utility Model Content

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0030] like Figures 1 to 3 As shown, this utility model provides an electrolysis device, which includes an electrolysis device, a positive electrode strengthening component 20 and a negative electrode strengthening component 30, which are respectively disposed on opposite sides of the electrolysis device.

[0031] The frame structure 10 is a hollow frame structure. The frame structure 10 is provided with an electrolysis chamber 13, an inlet flange 11 and an outlet flange 12 located at both ends of the electrolysis chamber 13. The interior of the electrolysis chamber 13 forms a reaction chamber space. The inlet flange 11 and the outlet flange 12 are respectively provided at both ends for the inflow and outflow of electrolyte.

[0032] Multiple reaction holes 16 are provided on the opposite side walls of the electrolysis chamber 13 at intervals. The reaction holes 16 penetrate the wall surface of the reaction holes 16, thereby connecting the reaction chamber space with the outside.

[0033] Optionally, the electrolysis chamber 13 has multiple reaction holes 16 distributed on it, and two adjacent reaction holes 16 are intersected by transverse and longitudinal reinforcing ribs 17 to form a spatial structure (such as a grid). Optionally, the electrolysis chamber 13 has at least one row of reaction holes 16 distributed on it, and each row has at least two reaction holes 16. For example, the upper sidewall of the electrolysis chamber 13 has two rows of reaction holes 16, and each row has 3-10 reaction holes. Further, each row has 7 reaction holes 16. The four reaction holes 16 form a grid-like structure, which is formed by the intersection and separation of transverse and longitudinal reinforcing ribs 17.

[0034] Optionally, the thickness of the reinforcing rib 17 is 1 / 3 to 1 / 2 of the thickness of the positive electrode plate 22, which ensures the strength of the cavity structure and provides an insertion channel for the positive electrode reaction section 221 or the negative electrode reaction section 321.

[0035] The structure of the positive electrode reinforcement assembly 20 is similar to that of the negative electrode reinforcement assembly 30, and can be understood by referring to the positive electrode reinforcement assembly 20. The positive electrode reinforcement assembly 20 includes a positive electrode reinforcement plate 21 and at least one positive electrode plate 22 fixed to the positive electrode reinforcement plate 21. The positive electrode plate 22 has multiple protruding positive electrode reaction portions 221. The surface of the positive electrode plate 22 is provided with multiple protruding positive electrode reaction portions 221 (such as columnar or plate-shaped protrusions), and at least some of the positive electrode reaction portions 221 are inserted into the reaction holes 16 and contact the electrolysis chamber 13 to form the anode reaction region.

[0036] Accordingly, the negative electrode reinforcement assembly 30 includes a negative electrode reinforcement plate 31 and at least one negative electrode plate 32 fixed to the negative electrode reinforcement plate 31. The negative electrode plate 32 has a plurality of protruding negative electrode reaction portions 321. At least a portion of the negative electrode reaction portions 321 are inserted into the reaction hole 16 and contact the electrolysis chamber 13 to form a cathode reaction region.

[0037] The positive electrode reinforcement component 20 and the negative electrode reinforcement component 30 are respectively attached and fixed to the opposite sides of the frame structure component 10. At least a portion of the positive electrode reaction part 221 is inserted into the reaction hole 16 and contacts the electrolysis chamber 13, and at least a portion of the negative electrode reaction part 321 is inserted into the reaction hole 16 and contacts the electrolysis chamber 13.

[0038] The electrolysis chamber 13 is provided with a rectangular hollow flow channel, and the reaction holes 16 penetrate through the long side wall and are distributed in at least one row (at least two in each row) along the flow channel direction to form a uniform electrode reaction area.

[0039] Work process: The fluid enters the reaction chamber space from the inlet flange 11, and when it flows through the reaction hole 16, it undergoes an electrolytic reaction with the inserted positive electrode reaction section 221 and negative electrode reaction section 321. The fluid after the reaction flows out from the outlet flange 12.

[0040] The reinforcing ribs 17 of the frame structure 10, together with the positive and negative electrode reinforcing components, form a composite support structure, reducing the deformation of the positive electrode plate 22 and the negative electrode plate 32 under the impact of the processed fluid. The multiple independent reaction sections formed by the reaction holes 16 increase the contact area between the positive electrode plate 22 and the negative electrode plate 32 and the fluid, and the reaction areas are evenly distributed.

[0041] The frame structure 10 has reaction holes 16 formed by the intersecting spaces of transverse and longitudinal reinforcing ribs 17. The thickness of the reinforcing ribs 17 is 1 / 3 to 1 / 2 of the thickness of the positive electrode plate 22. The reinforcing ribs 17 form part of the hole wall of the reaction holes 16. The electrolysis chamber 13 includes rectangular hollow channels, and the reaction holes 16 penetrate the long sidewall of the electrolysis chamber 13. The reinforcing ribs 17 are located on the long sidewall to form a hollow structure. The positive electrode reaction section 221 and the negative electrode reaction section 321 are inserted through the reaction holes 16 to further increase the contact area and improve the electrolysis efficiency.

[0042] Preferably, the ratio of the total end face area of ​​the positive electrode reaction section 221 to the cross-sectional area of ​​the flow channel inside the electrolysis chamber 13 is k, where 0.5 ≤ k ≤ 0.9. The cross-sectional area of ​​the flow channel inside the electrolysis chamber 13 is the inner surface area of ​​the long side wall of the electrolysis chamber 13. Multiple positive electrode reaction sections 221 are provided, and the end faces of the positive electrode reaction sections 221 are in contact with the flow channels inside the electrolysis chamber 13. The total end face area is the sum of the areas of the multiple positive electrode reaction sections 221. The larger the total end face area of ​​the positive electrode reaction sections 221, the larger the reaction contact area and the higher the reaction efficiency.

[0043] like Figures 1 to 3 As shown, in one embodiment, the frame structure 10 includes reinforcing ends 14 protruding from both ends of the electrolysis chamber 13. The cross-sectional dimensions of the reinforcing ends 14 are larger than the dimensions of the electrolysis chamber 13, forming a structure that is large at both ends and small in the middle. A mounting groove is formed between the reinforcing ends 14 and the outer wall of the electrolysis chamber 13, and the positive electrode reinforcing assembly 20 and the negative electrode reinforcing assembly 30 are respectively defined in the mounting groove.

[0044] Specifically, the electrolysis chamber 13 has mounting slots on both sides, namely the upper slot and the lower slot. The positive electrode reinforcement component 20 is installed in the upper slot, and the negative electrode reinforcement component 30 is installed in the lower slot.

[0045] Based on the above embodiments, the electrolysis device further includes an annular seal 50, which seals the mating surface of the positive electrode reinforcing component 20 and the frame structure component 10; and the seal 50 seals the mating surface of the negative electrode reinforcing component 30 and the frame structure component 10.

[0046] The positive electrode reinforcement component 20 and the negative electrode reinforcement component 30 are respectively attached and fixed to the opposite sides of the frame structure component 10, and locked to the frame structure component 10 by fasteners (such as bolts and screws) to enhance the overall structural sealing and impact resistance.

[0047] The annular seal 50 (such as a rubber seal ring) seals the mating surfaces of the positive electrode reinforcing component 20, the negative electrode reinforcing component 30, and the frame structure component 10, forming a sealing structure.

[0048] Furthermore, the frame structure 10 includes a blocking rib 15 protruding from the outer peripheral wall of the electrolysis chamber 13, and the seal 50 is located within the area surrounded by the blocking rib 15. The blocking rib 15 is a vertical rib structure that can surround to form an annular area for defining the annular seal 50. The outer surface of the seal 50 abuts against and is defined on the inner side of the blocking rib 15, thereby defining the direction of elastic deformation of the seal 50.

[0049] The blocking rib 15 is inserted into the positive electrode reinforcing assembly 20; and / or, the blocking rib 15 is inserted into the negative electrode reinforcing assembly 30. An annular seal 50 is disposed within the area surrounded by the blocking rib 15, which can be inserted into the mating grooves of the positive electrode reinforcing plate 21 / negative electrode reinforcing plate 31 to form a double sealing structure. It can also position the assembly of the positive electrode reinforcing plate 21 and the negative electrode reinforcing plate 31 to prevent circumferential displacement.

[0050] In one embodiment, the positive electrode reinforcing plate 21 and the frame structure 10 are locked together by fasteners, and the negative electrode reinforcing plate 31 and the frame structure 10 are locked together by fasteners.

[0051] The electrolysis unit also includes multiple clamping rings 40 clamping the outside of the positive electrode reinforcing plate 21 and the negative electrode reinforcing plate 31. The multiple clamping rings 40 are evenly distributed to tighten and lock the positive electrode reinforcing plate 21, the frame structure 10 and the negative electrode reinforcing plate 31, thereby improving the leakage resistance.

[0052] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
