Leakage tracing method and device for outdoor volatile substances

Abstract

The invention provides a leakage tracing method and device for outdoor volatile substances. The method comprises the steps: acquiring volatile substance information of all monitoring points in an outdoor area; for each to-be-processed component of each to-be-processed monitoring point, determining a leakage time period of the to-be-processed component at the monitoring point according to the concentration information of the to-be-processed component at each acquisition time point and the concentration reference value corresponding to the to-be-processed component; acquiring wind field data of the to-be-processed monitoring point, and determining a potential leakage area of the to-be-processed monitoring point according to the wind field data; and determining the leakage point of the to-be-processed component in the leakage time period according to the concentration information of the to-be-processed component in each monitoring point in the potential leakage area in the leakage time period. According to the method, real-time leakage monitoring of the volatile substances is achieved, the leakage situation can be found in time, the potential leakage area does not need to be inspected manually, the automation degree is high, and the equipment area difficult to reach by people can be effectively monitored.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for leak traceability of outdoor volatile substances. Background technique [0002] At present, the leakage of volatile organic compounds (VOCs) in chemical industry parks will lead to material loss, environmental pollution, and even huge casualties and damage accidents. The petrochemical industry is the main emission industry of VOCs from industrial sources in my country, with large emissions and mainly fugitive emissions. In order to implement the task of VOCs treatment, in related technologies, LDAR (Leak Detection And Repair, Leak Detection and Repair) is used to control the unorganized emission of VOCs in the equipment and installations of petrochemical enterprises, that is, to use fixed or portable detection equipment to quantitatively detect enterprises Valves and other sealing points in production equipment that are prone to VOCs lea...

Problems solved by technology

[0003] However, in the above-mentioned technology, the regular detection method is adopted, which cannot realize real-time VOCs leakage monitoring, and the leakage situation cannot be found in time. In addition, the above-mentioned technology uses a manual carrying detection instrument to inspect the potential leakage source, which has a low degree of automation and a large manpower burden. , and it is impossible to monitor equipment areas that are difficult for people to reach
