Tail gas corona treatment device based on annealing furnace and treatment method thereof

The invention relates to the technical field of annealing furnace tail gas treatment, and particularly discloses a tail gas corona treatment device based on an annealing furnace. The device comprises a treatment tank, a rotating mechanism and a corona mechanism, the rotating mechanism and the corona mechanism are arranged in the middle of the treatment tank, and the treatment tank is composed of a left half tank and a right half tank; the rotating mechanism is composed of a rotating shaft, a motor base arranged at the right end of the right half tank and a driving motor fixedly installed on the side face of the motor base. The corona mechanism is composed of discharge assemblies fixedly sleeving the two ends of the rotating shaft. According to the device, electric shock rods which are uniformly distributed are oppositely inserted into the side surfaces of the fixed discs at the two ends of the rotating shaft, and discharge cones are uniformly distributed on the electric shock rods, so that the corona discharg
