The present disclosure relates to an exhaust purification device for an aerospace plane, which effectively solves the problems of existing devices such as fast flow rate of the exhaust and low purification efficiency of the swirling exhaust. The technical solution ofthe present disclosure is as follows. The exhaust purification device includes a housing, and the left end and the right end of the housing are respectively provided with an air inlet and an air outlet. The air inlet is provided with a plurality of inclined spoilers which are uniformly and fixedly connected to the inner side wall of the housing. A straight deflector is fixedly connected to the right end of each of the plurality of inclined spoilers. The right side of the straight deflector is provided with a flow uniformizing structure that is fixedly connected in the housing. The right side of the flow uniformizing structure is successively provided with an activated carbon and a high-low voltage electric field which are fixedly connected in the housing. The flow uniformizing structure includes a ventilation channel fixedly connected to the housing, and the inner diameter of the ventilation channel is smaller than the inner diameter of the housing. A plurality of diversion slopes are fixedly connected between the two ends of the ventilation channel and the inner side wall of the housing. The plurality of diversion slopes are provided with a plurality of flow uniformizing holes. The exhaust purification device of the present disclosure has a simple structure and strong practicability, which can efficiently filter harmful substances in the exhaust of the aircraft.
