Emulsifying-type aerobic fermentation tank

The present invention discloses an emulsifying-type aerobic fermentation tank. According to the aerobic fermentation tank in the prior art, increase of compressed air consumption and improvement of stirring motor power can not significantly increase specific yield, and can cause energy consumption increasing, product cost improving, equipment cost increasing and operating environment deterioration. The emulsifying-type aerobic fermentation tank of the present invention comprises a tank body and a gas-liquid mixing circulation apparatus, wherein the gas-liquid mixing circulation apparatus is located inside the tank body, and has at least two stages of gas-liquid mixers. The gas-liquid mixing circulation apparatus is arranged vertically. The tank body is provided with a tank body gas inlet pipe and a fermented liquid inlet pipe. The tank is characterized in that: a self-suction air ejection emulsifying supercharging device is arranged between the gas-liquid mixing circulation apparatus and the inner wall of the
