A defrosting device suitable for a circular pipeline comprises a base, a displacement part, a control handle, a PLC and a purging part. The base is arranged under the pipeline, and the center line of the base is parallel to the axis of the pipeline. The displacement part is arranged on the upper end surface of the base; the purging part is arranged on the upper end surface of the displacement part; the control handle is held by a worker; the displacement part comprises a motor, a lead screw, a lead screw nut and a connecting block; a shell of the motor is arranged on the upper end face of the base. One end of the lead screw is connected with an output shaft of the motor, and the other end of the lead screw is connected with the bearing seat; a lead screw nut is arranged at the lower end of the connecting block, and the lead screw penetrates through the lead screw nut. The pipeline frost removing efficiency is improved, and the labor intensity of workers is reduced. 一种适用于圆形管道的除霜装置，包括底座、位移部分、控制手柄、PLC和吹扫部分；所述底座设
