Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte filtration, in particular to an all-vanadium battery electrolyte filtration device. Background Art

[0002] With the accelerated development of renewable energy, distributed microgrids and smart energy, energy storage technology, which plays an important role in improving the grid connection rate of renewable energy and balancing the stability of the power grid, has attracted more and more attention. Among the many large-capacity energy storage technology routes, all-vanadium liquid flow batteries have stood out.

[0003] Compared with other energy storage technologies, all-vanadium liquid flow battery energy storage technology has become one of the preferred technologies for large-scale energy storage due to its outstanding advantages such as long service life, large scale, safety and reliability. As one of the key materials in all-vanadium liquid flow batteries, vanadium electrolyte directly affects the efficiency of vanadium batteries. During the operation of vanadium batteries, the electrolyte of vanadium batteries will precipitate with the change of temperature to form precipitation. When it enters the battery stack under the action of the pump, it will cause irreversible blockage and affect its electrochemical reaction efficiency; in addition, as the electrolyte circulates in the battery system, it will flush the electrode material. The debris of the electrode material flushed down will circulate in the battery stack again, which will also cause the battery stack to be blocked, affecting the efficiency of the battery; the electrolyte storage tank will isolate the electrolyte from the air by means of organic liquid seal. Under the action of the pump, a part of the organic solvent will be mixed in the electrolyte and enter the battery stack, which will also cause a large amount of organic matter to be deposited in the battery stack, thereby affecting the efficiency of the battery.

[0004] As mentioned above, the electrolyte filtration link of vanadium batteries is particularly important. At present, most strategies adopted are to install a Y-type filter before the inlet of the battery stack. Although this filter can play a filtering role, it is fixedly installed inside the equipment, which is not convenient for subsequent cleaning and replacement. The operation is too inconvenient, so further improvement is needed.
