Emulsification type aerobic fermentation tank

The utility model discloses an emulsification type aerobic fermentation tank. Existing aerobic fermentation tanks are not remarkable in increasing yield per unit by means of addition of usage of compressed air and increasing of power of a stirring motor, and causes increased energy consumption, the increased product cost, increased equipment construction cost and degradation of operation environment. The emulsification type aerobic fermentation tank comprises a tank body and a gas-liquid mixing and recycling device which is provided with at least two stages of gas-liquid mixer and is vertically arranged inside the tank body, and the tank body is provided with a tank body air inlet pipe and a fermentation broth inlet pipe. The emulsification type aerobic fermentation tank is characterized in that a self-absorption air injection emulsification supercharging device is arranged between the gas-liquid mixing and recycling device and the inner wall of the tank body.
