Scale deposit treatment auxiliary device with large diameter

The utility model relates to a scale deposit treating auxiliary device with a large caliber, which is a working auxiliary machine (2) composed of an inner pipe (13) and an outer pipe (14), wherein a plurality of energy converters (3 and 7) are distributed between the inner pipe (13) and the outer pipe (14), and the energy converters (3 and 7) are fixed on end covers on both ends of the outer pipe (14). The front end of the inner pipe (13) is provided with a water outlet (10) and the back end of the inner pipe is provided with a water outlet (15); a water insulation cap (12) is arranged in the inner pipe (13), and the energy converter (3) is an electrode or an ion rod. The utility model solves the problem that the existing scale deposit treating device can not be adapted to pipelines with large calibers and makes the application range of the existing product widened, and simultaneously, the auxiliary machine can be used separately and many auxiliary machines can be used by connecting in series or in parallel.
