The utility model belongs to the technical field of flow batteries, and particularly relates to a gas circulation system of a flow battery. The flow battery gas circulation system comprises a positive electrode liquid storage tank, a negative electrode liquid storage tank, a gas inlet pipeline, a gas exhaust pipeline, a gas pressure balance pipeline and a gas transfer device, the upstream end of the air inlet pipeline is positioned above the liquid level of the positive electrode liquid storage tank; the downstream end of the gas inlet pipeline is communicated with the inlet of the gas transfer device; the outlet of the gas transfer device is communicated with the upstream end of the exhaust pipeline; the downstream end of the exhaust pipeline is located below the liquid level of the negative electrode liquid storage tank. And two ends of the air pressure balance pipeline are respectively communicated to positions above the liquid levels of the positive electrode liquid storage tank and the negative electrode liquid storage tank. The gas transfer and reactive gas absorption process is realized, volatile gas and toxic waste gas can be quickly and effectively absorbed, the pressure balance of the positive and negative electrode liquid storage tanks is maintained, the change of active components of the electrolyte during operation is avoided, and the safety and high efficiency of long-time operation of the flow battery are maintained.
