The invention provides an efficient internal circulation gradient-free reaction device. The catalyst bed is arranged in the reaction cavity and abuts against the side wall of the reaction kettle in a contact mode, the airflow channel is arranged in the side wall of the reaction kettle, and the length of the airflow channel is larger than the height of the catalyst bed. The impeller assembly and the inner wall of the reaction cavity are arranged in the mode that when the impeller rotates, the circumferential edge of the impeller assembly and the inner wall, located above the lower end opening of the airflow channel, of the reaction cavity form air seal. All side walls of the catalyst bed are in contact with the side wall of the reaction kettle, so that the heat conduction efficiency of the reaction kettle to the catalyst bed is improved, and the reaction efficiency is improved. The length of the gas flow channel is greater than the height of the catalyst bed, so that the side wall of the reaction kettle can fu
