The utility model discloses an airflow distribution plate device of a fluidized bed reactor. The airflow distribution plate device comprises an airflow distribution plate, wherein the airflow distribution plate is an elliptical rotary body which is uniform in thickness, the strength of the distribution plate is enhanced, and the aperture ratio of the distribution plate is increased; holes are uniformly formed in the airflow distribution plate, a tubular nozzle is arranged on the airflow distribution plate and vertically arranged below the airflow distribution plate, a small hole is formed in the bottom of the tubular nozzle, and a guide plate is arranged in the tubular nozzle. According to the airflow distribution plate device, by virtue of changing the shape of the distribution plate, the structure of the nozzle and the arrangement of the nozzle, the impaction and abrasion to the inner wall of equipment are reduced, the strength of the distribution plate is improved, the reaction residence time of a mixed ga
