Gas pipeline-hazardous chemical enterprise coupling hidden danger identification and risk assessment method and system

Abstract

The present invention provides a method and system for hidden danger identification and risk assessment of gas pipeline-hazardous chemical enterprises. This method is applicable to the whole composed of hazardous chemical enterprises and their surrounding gas pipelines. Its function is to quickly identify once the gas pipeline fails Identify the affected hazardous chemical enterprises, and conduct risk assessment based on the scale of the enterprise and the type of hazardous substances. The judging method is to firstly analyze the disaster intensity of several accident modes of the gas pipeline, and determine the damage radius. The damage scope of the accident is determined according to the damage radius. If the enterprise is within this range, it is considered that the enterprise can be affected by the leakage of the gas pipeline, that is, there is a potential accident. This method also constructs an accident consequence assessment system for hazardous chemical enterprises and a gas pipeline leakage possibility assessment system. Therefore, the risk calculation of gas pipeline leakage affecting hazardous chemical enterprises is determined by the product of pipeline leakage and the accident consequences of hazardous chemical enterprises. Finally, this model classifies this risk.

Description

technical field [0001] The invention relates to the technical field of gas safety supervision, in particular to a method and system for identifying hidden dangers and assessing risks in gas pipeline-hazardous chemical enterprise coupling. Background technique [0002] As the urbanization process continues to intensify, old and new pipe networks are criss-crossed and even parallel, and cities are facing more and more public safety risks, which pose a huge threat to the normal development of urban society and economy. Because of the interdependence and mutual restriction within and between social systems, chain effects often occur, which shows that the occurrence of disasters together will trigger a series of secondary disasters. When the two risks converge, their uncertain state will be amplified, and the impact will spread from one geographical space to another wider geographical space. [0003] Due to the particularity of hazardous chemical enterprises, they are easily aff...

Problems solved by technology

The disadvantage of this method is that it evaluates the risks of various underground pipelines, but does not take into account the changes in the coupling risks between gas pipelines and surrounding hazardous chemical enterprises. The assessment method is relatively simple and the practicability is not high

[0006] Explosions and fire accidents caused by leakage of urban gas pipelines will cause surrounding hazardous chemical enterprises to be in an unsafe state and constitute a hidden danger
