Problems solved by technology
[0003] In the leakage accident detection of long-distance transmission pipelines such as petroleum and petrochemical industries, the temperature-sensing optical fiber system has a precedent, but the existing detection methods are still unable to effectively control the leakage of pulverized coal transmission pipelines
The reason is that the detection accuracy of the system is low, and it is impossible to accurately locate the pipeline leakage point; the second is that it does not have an early warning function, and can only send out a signal after a pipeline leakage accident occurs, and it is powerless to suppress the occurrence of the accident.

The invention discloses a coal dust transmission pipeline leakage early warning detection method. A pipe wall temperature is monitored in real time by use of a temperature early warning detector arranged on an easily damaged pipe segment of a coal duct transmission pipeline, real-time temperature data is sent to an analysis control host computer arranged at a rear end through a fiber or bus mode, the analysis control host computer analyzes received data through a program arranged in advance, and possible safety hidden risks are determined through abnormal change of the pipe wall temperature of the transmission pipeline, so that pipeline leakage hidden risks are eliminated at an early stage, accidents are prevented from worsening or further development, comprehensive and accurate mastery of the damage of the transmission pipeline is realized, and the purpose of active protection is achieved.
Description
technical field [0001] The invention belongs to the technical field of pipeline leakage detection, and in particular relates to a method for early warning and detection of coal powder transmission pipeline leakage. Background technique [0002] The pulverized coal leakage accident is that during the pulverized coal transmission process, the pulverized coal transported under high pressure repeatedly rubs against the pipe wall, which damages and thins the wear-resistant ceramic lining of the pipe elbow, tee, variable diameter, etc. Falling off, resulting in the eventual damage of the pipeline and the accident of pulverized coal leakage. When a pulverized coal leakage accident occurs, usually dozens or even hundreds of tons of high-temperature and high-pressure pulverized coal leak into the air, forming a flammable and explosive dust environment near the leakage point, which can easily lead to serious safety accidents. [0003] In the leakage accident detection of long-distanc...
