Risk source leakage source positioning and tracing method and system based on risk identification

Abstract

The invention discloses a risk source leakage source positioning and tracing method based on risk identification. The risk source leakage source positioning and tracing method comprises the followingsteps of identifying positions of danger sources of in-site pipelines; selecting an adapted gas leakage diffusion model, and developing an in-site pipeline monitoring equipment arrangement scheme; according to the in-site pipeline monitoring equipment arrangement scheme, arranging a plurality of gas leakage monitoring equipment in the pipeline site; and enabling the gas leakage monitoring equipment to collect gas leakage data of the pipeline site in a real-time manner, and performing leakage source positioning and tracing analysis on the collected gas leakage data in a manner of combining thegas leakage diffusion model with the in-site pipeline monitoring equipment arrangement scheme, so as to obtain the source strength and a specific position at a gas leakage source. The invention also discloses a system of the risk source leakage source positioning and tracing method based on the risk identification. According to the risk source leakage source positioning and tracing method disclosed by the invention, equipment for monitoring the risk source is arranged in a targeted manner, so that leakage can be detected in a real-time manner, and the position of the leakage source can also beaccurately positioned, manual inspection cost is reduced, and personal safety risk of seeking a leakage source is reduced.

Description

technical field [0001] The invention relates to the technical field of detection methods for hazardous sources used in petrochemical industry, in particular to a risk identification-based method for identifying leaks and tracing sources of risks and a system thereof. Background technique [0002] Toxic and harmful gas leakage points in petrochemical plants are many and wide-ranging, the risk is not easy to identify, and conventional detection methods are reluctant. At present, there are two main conventional detection methods: [0003] 1. Use artificial portable instruments for detection. Artificial portable instruments mainly use portable flame ionization detectors and infrared thermal imaging cameras. The detection cycle is generally quarterly or annual. The detection cycle is long and real-time. The detection accuracy is affected by human operation. Habits and environmental factors have a great influence, and real-time detection of leakage sources and identification of ri...

Problems solved by technology

[0003] 1. Use artificial portable instruments for detection. Artificial portable instruments mainly use portable flame ionization detectors and infrared thermal imaging cameras. The detection cycle is generally quarterly or annual. The detection cycle is long and real-time. The detection accuracy is affected by human operation. Habits and environmental factors are greatly affected, and it is impossible to detect leakage sources in real time and identify risk sources

In addition, due to the use of manual portable instruments for measurement, the monitoring data of different equipment are independent and offline, so it is impossible to give early warning of potential or existing risks, and it is impossible to judge the exact location of the leakage source through data fusion of different monitoring equipment;

[0004] 2. The fixed monitor is used for detection. The fixed monitor is mainly a variety of toxic gas and combustible gas detectors. "Alarm Controller", most of the alarms set the threshold value to generate alarm information, and cannot form linkage with other devices in a certain area and coordinate the processing of monitoring data, resulting in a high rate of false alarms

In addition, due to the fact that the points are only arranged on the basis of meeting the requirements, there are repeated and isolated points on the site, and the potential dangerous points cannot be identified by work, resulting in a limited monitoring range and insignificant effects. It is difficult to realize the detection of major potential hazards. Monitoring and confirmation of leak source location
