Cause analysis of Shiyan accident in Hubei Province

Cause analysis of Shiyan accident in Hubei Province
On June 17, the State Council Safety Committee organized a national teleconference on work safety, at which Wang Yong, State Councilor and deputy director of the State Council safety committee, presided over and briefed the national work safety situation since this year.
The meeting proposed to carry out in-depth safety rectification in gas pipeline, chemical industry, hazardous chemical transportation and other fields, and comprehensively investigate and control various major risks and hidden dangers. We will promote automated and intelligent operations in high-risk industries.
Wang Yong also analyzed the cause of the gas explosion accident in Shiyan, Hubei Province, and pointed out the problems of real-time detection and online detection. High risk industries have been renovated for three years, and gas pipelines have been deployed by the Party Central Committee and the State Council for another three years. Online monitoring of gas pipeline and central control of gas leakage should be carried out. There is no problem with the relevant technology, but we do not invest in it. With such a large flow and such a high frequency, gas companies have not spent money on preventing major hidden dangers and risks in technological transformation.

China City Gas Association's proposal on strengthening
Notice on strict prevention of major accidents in urban gas safety management

At the same time, China City Gas Association proposed to adhere to scientific and technological innovation and technology guidance, promote the application of new technologies and new products such as intelligent pressure regulating box, intelligent gas meter, safety cut-off device and safety gas stove in the industry, and implement normal prevention for gas leakage, pipe network operation and indoor safety, so as to realize timely warning and emergency disposal. We should actively use the Internet of things, big data, artificial intelligence and other technologies to promote the innovation of management means, management mode, and management concept. We should establish and improve the geographic information system, and manage the gas pipeline network well. In particular, we should implement dynamic management for the pipeline sections that have been running for many years, aging, and serious accidents, so as to ensure the safe operation. It is necessary to establish the information management system of bottled liquefied gas, adopt technologies such as electronic labels and two-dimensional codes, realize the whole process tracking and life cycle traceability management of filling, sales, distribution and cylinder use, promote the development of gas industry from informatization and digitization to intelligence, and continuously improve the gas safety management and control ability.

Laser absorption spectroscopy is the most advanced gas detection technology in the world. Hanhai photoelectric system holds the research achievements of laser absorption spectrum detection, and is the leader in technology and market application in this field. Products and technologies are always in the forefront of the research and development and application of laser spectrum technology in the world, and have the overall advantages of domestic and international advanced recognized by the former State Administration of safety.
Compared with the traditional dangerous gas monitoring method, the main advantages of laser gas detection technology and products are: the laser is the working principle, which can realize large-scale, regional, active and high sensitivity monitoring, and anti electromagnetic interference; The specific monitoring point does not need power supply and oxygen for chemical reaction, and can ensure the essential safety by normal monitoring in the hypoxia environment of plateau. The essence of the existing technology is improved in the aspects of monitoring accuracy, reaction speed, operation and maintenance cost, convenience of use, and long service life. The advantages of maintenance free, no calibration and simple operation of monitoring equipment can be realized, and the cost can be reduced and economic performance can be improved.
Therefore, Hanhai photoelectric recommends that the safety of gas leakage warning and storage monitoring of hazardous chemicals can be realized quickly by the application of laser spectrum absorption technology. To protect the safety of enterprises and cities.
