High-temperature steam leakage detecting and positioning method and system

Abstract

The invention is suitable for the technical field of steam leakage detection, and particularly relates to a high-temperature steam leakage detection positioning method and system, and the method comprises the steps: S100, obtaining a PID diagram in a production region, marking a steam pipeline which comprises a steam main network and a bypass, and determining a winding mode of a thermosensitive cable, the thermosensitive cable is arranged on the outer side of the steam pipeline in parallel, and the thermosensitive cable is wound on the outer side of the steam pipeline at the reducing joint and the flange joint; and S200, observation nodes are arranged on the steam pipe network, and currents at the observation nodes are collected. According to the invention, by constructing the array, the detection result can be recorded in time, the space occupied by storage is greatly reduced, the detection result can be quickly processed, and by generating the detection report graph, the pipeline with steam leakage can be quickly positioned, the hidden danger disposal time is greatly shortened, and the resource waste caused by steam leakage is reduced. And the influence on normal production is reduced.
