Flow battery generator system

The invention discloses a flow battery generator system which comprises a zinc-air battery stack, a lithium battery stack, a control mechanism, a liquid storage tank, a pump, an electrolyte supplementing tank, a cyclone magnetic separator and a crystal grain collecting bottle. The control mechanism comprises a data collector and a controller; the magnetic cyclone separator is arranged on a passage between the zinc-air cell stack and the liquid storage tank and is configured to be used for separating aluminum hydroxide particles generated in the electrolyte; and the crystal grain collecting bottle is configured to be capable of recycling aluminum hydroxide particles generated in the electrolyte. A rapid heating system is added, a lithium battery stack is used for supplying power, and a microwave heating plate and a heating rod are used for heating together; in the system, the electrolyte can be magnetically separated and purified, and the ion concentration of the electrolyte is monitored and supplemented in re
