Description

Filter equipment of inside washing Technical Field The utility model relates to the technical field of battery production, in particular to a filter device for internal washing. Background All-vanadium redox flow battery (Vanadium Redox Battery, abbreviated as VRB) is one of the important technical routes of high-capacity energy storage power stations, is the flow battery technology which is most widely researched and applied at present, and is different from a lithium battery used in small application scenes such as small fields of mobile phones, computers, automobiles and the like, and the vanadium battery can provide the energy storage capacity with super-large capacity and super-long charge and discharge time, is safe and reliable and has almost unlimited cycle life, so the vanadium battery is known as an electric bank. The method is mainly used for building energy storage power stations, replacing oil machines, standby power supplies and the like. The working principle of the charging and discharging of the vanadium battery is that vanadium ion solutions with different valence states are respectively used as active substances of an anode and a cathode and are respectively stored in respective energy liquid (electrolyte) storage tanks.
