Electric heat tracing device for pipeline based on thermal power compensation

Abstract

The application discloses a pipeline electric heat tracing device based on heat work compensation and belongs to the technical field of electric heat tracing devices. The pipeline electric heat tracing device comprises a reinforcing shell, a pipe laying device, a wire feeding device, a wire collecting device, a skin effect cable and a driving device. The heat tracing mode of the application is to break the core of each heat tracing steel pipe, and the heat tracing steel pipes are independent of each other. The automatic arrangement of the heat tracing steel pipes and the skin effect cable is realized by the pipe laying device, so that the heating of the surrounding of the pipeline is more uniform. When special-shaped equipment such as a filter and a valve appears in the pipeline, the skin effect cable is lengthened by the cooperation of the wire collecting device and the wire feeding device, and is freely wound on the special-shaped equipment, so that the problem that the special-shaped equipment is difficult to heat is overcome. The whole pipe laying device and the reinforcing shell are designed to be detachable, each pipe laying device is disconnected for replacement of the heat tracing steel pipe, and even if the heat tracing steel pipe has a cavity, subsequent dismounting or cutting of the heat tracing steel pipe does not affect the operation of the whole heat tracing loop.
