Abstract

The invention belongs to the technical field of hazardous chemical substance leakage investigation, and discloses a hazardous chemical substance leakage qualitative detection method and system, and the method comprises the steps: obtaining infrared imaging data of a hazardous chemical substance leakage site, and determining a hazardous chemical substance leakage source and a leakage region of the leakage source according to the infrared imaging data; collecting and analyzing spectral data of the leakage area, and determining the type and diffusion track of leakage substances of the leakage area according to the spectral data; and acquiring types and diffusion tracks of leakage substances in all leakage areas of the hazardous chemical substance leakage site, and establishing a leakage distribution diagram of the hazardous chemical substances. According to the method, on the basis of locking a hazardous chemical substance leakage source through infrared imaging, spectral data collection and analysis of a leakage area are carried out, the type and diffusion track of leaked substances can be rapidly and qualitatively detected within several seconds, the detection speed is high, and the detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of hazardous chemical leakage detection, in particular to a method for qualitative detection of hazardous chemical leakage and a qualitative detection and detection system for hazardous chemical leakage. Background technique [0002] Most of the raw materials, semi-finished products, by-products, and wastes used in the production of petrochemical products are hazardous chemicals with flammable, explosive, toxic and harmful properties. High temperature and high pressure conditions can easily lead to safety production accidents. Due to the unclear quantity, content, and storage methods of hazardous chemicals in the warehouse, when a hazardous chemical leakage accident occurs, it will cause great obstacles to emergency rescue. When a hazardous chemical leakage accident occurs, it is the key to carry out scientific rescue to grasp the types of hazardous chemicals leaked on site and track the area affected by th...
