The utility model discloses an industrial double-air-inlet type centrifugal fan which comprises a base, a first air inlet pipe, a second air inlet pipe and an electric push rod. The centrifugal fan has the advantages that through the design of the first air inlet pipe, the second air inlet pipe, the electric push rod, the driving connecting rod, the fan blades and the rotating shaft, double-opening air inlet of the centrifugal fan can be achieved, the instantaneous air inlet amount of the centrifugal fan is effectively increased, the ventilation capacity of the centrifugal fan is improved, and the service life of the centrifugal fan is prolonged. The second air inlet pipe can be automatically opened and closed according to actual use requirements, the air inlet amount of the centrifugal fan is conveniently adjusted, the complexity of manual adjustment is avoided, and the use flexibility of the centrifugal fan is improved; the position of the motor can be conveniently adjusted when the centrifugal fan is insta
