Zheng Xiaoping, a project chief scientist and professor at Beijing University of Chemical Technology, said that the project will be a dual-drive research orientation to achieve overall goals and solve key scientific issues. The overall goal is to establish a comprehensive platform for information perception and emergency response in the whole process of accidents, with the telemetry of hazardous chemicals as the core, to eliminate the delay and failure of information perception. The migration and transformation of accident materials in the whole process of hazardous chemicals accidents and their telemetry theory and methods at different spatial scales have become the key scientific problems to be solved. The project will establish the accident cause theory by studying the numerical model and monitoring mode of accident materials in the process of disaster, disaster and disaster reduction, and establish the corresponding relationship between microwave spectrum and molecular structure, in order to fully realize the direct detection of accident materials. .
According to reports, the project has developed terahertz detection technology for hazardous chemicals, 360-degree rotating infrared telemetry technology, and researched the atmospheric migration and diffusion process of hazardous chemicals and emergency evacuation of large-scale population, and designed more feasible. Program. The researchers said that the technology can directly detect accident materials within 7000 meters. At present, mass spectrometry technology is commonly used in the detection of chemical substances in the world, but the sampling method and anti-interference ability of the technology in a complicated environment are difficult to meet the scene monitoring of dangerous chemicals accidents.
In the future, the project will focus on the environmental adaptability problems and intelligent identification of terahertz detection and infrared telemetry of hazardous chemicals, and embed the atmospheric migration and diffusion process and large-scale emergency evacuation schemes into the equipment to establish dangerous chemicals accidents. Large-scale system device for telemetry and early warning of the whole process. At that time, the detection device will be installed in key areas (such as oil and gas engineering, chemical workshops, airport security inspection, important public places), helicopters, patrol cars, robots, etc. with load detection devices to achieve seamless telemetry in the monitoring of three-dimensional space. To prevent chemical process accidents and poisonous terrorist attacks.
According to the survey, hazardous chemicals accidents accounted for more than 50% of major global accidents. From January to July 2011, there were 343 accidents in the petrochemical industry at home and abroad, of which 35.3% were leakage of hazardous chemicals, ranking first; while fires accounted for 31.8% and explosions accounted for 26.5%, which was largely due to Hazardous chemicals leaked.
