Abstract

The invention discloses an electrolyte suction device and an electrolyte storage tank comprising the electrolyte suction device. The electrolyte suction device comprises a main pipe and a plurality of branch pipes, wherein the plurality of branch pipes are vertically connected to the main pipe and communicated with the main pipe; and a plurality of suction holes are formed in surfaces, which are opposite to the main pipe, of the plurality of branch pipes. According to the electrolyte suction device, electrolyte at the bottom of the storage tank can be sucked by the plurality of suction holes in the branch pipes, the upper electrolyte is transferred to the bottom of the storage tank under the action of gravity, and the liquidity of the electrolyte inside the storage tank in the gravity direction is improved. Meanwhile, a certain flow disturbance is formed around the suction holes in the process of enabling the electrolyte to enter the branch pipes through the plurality of suction holes, so that the liquidity of the electrolyte inside the storage tank in the horizontal direction is enhanced. When the electrolyte suction device is adopted in the electrolyte storage tank, the liquidity of the electrolyte inside the storage tank is enhanced.

Description

technical field [0001] The invention relates to an electrolyte suction device and an electrolyte storage tank containing the same. Background technique [0002] The all-vanadium redox flow battery is a new type of green energy storage battery with relatively young technology. It uses the oxidation-reduction reaction of vanadium ion pairs in different valence states to realize the mutual conversion of electrical energy and chemical energy. It is especially suitable for large-capacity energy storage occasions. The vanadium battery energy storage system is mainly composed of a stack system, a power load system and an electrolyte delivery system. The vanadium battery uses vanadium ions of different valence states in the electrolyte as positive and negative active materials, which are respectively installed in two electrolyte storage tanks, and are sent to the positive and negative reaction areas of the stack through an external delivery pump. After the electrochemical reaction ...
