Description

Technical Field

[0001] This utility model relates to the field of vanadium electrolyte, and more specifically, to a device for adsorbing and regenerating impurities in vanadium electrolyte. Background Technology

[0002] Vanadium redox electrolyte is the core energy storage medium of vanadium redox flow batteries. It is stored in the form of sulfuric acid solution containing vanadium ions of different valence states at the positive and negative electrodes, and achieves efficient conversion of electrical energy and chemical energy through redox reactions. Its performance is significantly affected by impurities (such as grease, colloids, high-valence vanadium, and metal ions), and it needs to maintain high purity through adsorption and regeneration devices. At the same time, it has the characteristics of being recyclable, environmentally friendly and pollution-free. It is a key material to ensure the long life, high safety and large-scale energy storage application of vanadium batteries.

[0003] A search revealed that Chinese patent CN116130691A discloses a "method for iron removal and regeneration of vanadium redox flow battery electrolyte." The technical solution involves mixing sulfonated phosphonic acid resin, carbon materials, and a binder, adding them to an organic solvent, stirring, coating the resulting slurry onto a graphite plate surface, and drying to obtain a composite electrode. The composite electrode is then placed in a capacitor deionization device, and the vanadium redox flow battery electrolyte to be treated is introduced. Adsorption is performed under DC voltage for 2–6 hours, and the first-stage treated electrolyte is discharged. A desorbent is then introduced to desorb the composite electrode, followed by rinsing with deionized water to obtain a regenerated composite electrode. Finally, the first-stage treated electrolyte is subjected to 2–5 capacitor deionization treatments according to the described adsorption and desorption process to obtain an iron-regenerated vanadium redox flow battery electrolyte. This invention features a simple process, requires no additives, has low cost, minimizes loss of active ingredients, and is environmentally friendly. It can significantly improve the performance of the vanadium redox flow battery electrolyte after iron removal, but it still has the following drawbacks: (1) The vanadium electrolyte impurity adsorption and regeneration devices currently available on the market do not provide the effect of quick replacement of adsorption components, which affects the progress of subsequent work, increases the number of operating steps for staff, increases the overall working time, reduces the overall work efficiency, and is not conducive to the long-term use of the vanadium electrolyte impurity adsorption and regeneration devices.

[0004] (2) The lack of a suitable temperature for long-term maintenance increases the damage rate during the adsorption and regeneration process of the vanadium electrolyte, raises the operating costs of subsequent work, and affects the progress of subsequent work. Therefore, a vanadium electrolyte impurity adsorption and regeneration device is proposed. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] As shown in 1-5, this embodiment proposes a vanadium electrolyte impurity adsorption and regeneration device, including a temporary storage frame 1. A connecting threaded pipe 2 is fixedly connected to one side of the temporary storage frame 1. An internal threaded lock 3 is movably connected to the outer wall of the connecting threaded pipe 2. A movable threaded pipe 4 is movably connected to the inner wall of the internal threaded lock 3. A porous carbon material plate 5 is fixedly connected to one end of the movable threaded pipe 4. A leak-proof rubber ring 6 is fixedly connected to one side of the porous carbon material plate 5. An insertion strip 7 is fixedly connected to the outer wall of the movable threaded pipe 4.

[0022] An inner spring 8 is fixedly connected inside the insertion strip 7. One end of the inner spring 8 is fixedly connected to a locking arc block 9. A locking frame 10 is movably connected to one side of the locking arc block 9. An external threaded tube 11 is fixedly connected to one side of the locking frame 10. An external threaded buckle 12 is movably connected to the outer wall of the external threaded tube 11. This provides a quick replacement of adsorption components for the vanadium electrolyte impurity adsorption and regeneration device, thereby accelerating the progress of subsequent work, reducing the number of work steps for staff, reducing the overall work time, improving the overall work efficiency, and facilitating the long-term use of the vanadium electrolyte impurity adsorption and regeneration device.

[0023] As shown in 1-5, in a preferred embodiment, based on the above method, a lower frame 13 is fixedly connected to the bottom of the storage frame 1, and the length and width of the lower frame 13 are equal to the length and width of the storage frame 1, which facilitates the connection of other working parts. A heating column 14 is fixedly connected inside the lower frame 13, and there are five heating columns 14, which can provide constant temperature preservation for the material in the storage frame 1. A side motor 15 is fixedly connected to one side of the storage frame 1, and the output shaft of the side motor 15 is fixedly connected to a rotating column 16 through a coupling, which facilitates the connection of other parts. A bearing 17 is fixedly connected to the outer wall of the rotating column 16, and a flow regulating plate 18 is fixedly connected to the outer wall of the rotating column 16, which can make the flow regulating plate 18 rotate, thereby allowing the liquid to flow vertically.

[0024] A discharge pipe 19 is fixedly connected to one side of the temporary storage frame 1, and a pipe port 20 is movably connected to one end of the discharge pipe 19 to facilitate the discharge of materials from the temporary storage frame 1.

[0025] One side of the locking arc block 9 is movably connected to the interior of the insertion strip 7 via the inner spring 8, and there are six locking arc blocks 9, six inner springs 8, six insertion strips 7 and six locking frames 10, which facilitates the quick disassembly and replacement of the adsorption structure.

[0026] Specifically, in use, the vanadium electrolyte impurity adsorption and regeneration device locks the external threaded tube 11 to the external feed tube via the external threaded locking buckle 12. Then, the movable threaded tube 4 is moved so that the insertion strip 7 is aligned with the locking frame 10 and inserted. The arc surface of the locking arc block 9 is pressed, causing the inner spring 8 to contract, thus retracting the locking arc block 9 into the insertion strip 7 until it pops out on the other side of the locking frame 10, completing the engagement. This allows the porous carbon material plate 5 to be positioned between the external threaded tube 11 and the movable threaded tube 11. Between the pipes 4, the connecting threaded pipe 2 and the movable threaded pipe 4 are locked by the internal threaded locking buckle 3. When the liquid material passes through the porous carbon material plate 5, it will adsorb the grease, colloid and organic impurities in it, so that the material can be regenerated and reused. At that time, after the vanadium electrolyte enters the temporary storage frame 1, the heating column 14 works to heat it, so that the material is kept at a constant temperature. At the same time, the side motor 15 works, and the output shaft of the side motor 15 rotates to make the flow regulating plate 18 rotate, which also makes the internal liquid material heat up more evenly.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
