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

Abstract

The invention provides a gas pipeline-hazardous chemical enterprise coupling hidden danger identification and risk assessment method and system. The method is suitable for a whole composed of a hazardous chemical enterprise and surrounding gas pipelines, and has the function of quickly identifying the affected hazardous chemical enterprise once the gas pipeline fails and performing risk assessment on dangerous goods types and the like according to the scale of the enterprise. The judgment method comprises the following steps that the disaster-causing intensities of several accident modes of the gas pipeline are analyzed, and the damage radius of the gas pipeline is determined; the damage range of the accident is determined according to the damage radius; if the enterprise is within the range, it is considered that the enterprise can be affected by gas pipeline leakage, that is, potential accidents exist. The method also constructs an accident consequence evaluation system of the hazardous chemical enterprise and a gas pipeline leakage possibility evaluation system. Therefore, the risk calculation of the hazardous chemical enterprise influenced by the gas pipeline leakage is determined by the product of the pipeline leakage and the accident consequence of the hazardous chemical enterprise. And finally, the risk is graded by the model.

Description

technical field [0001] The present invention relates to the technical field of gas safety supervision, in particular to a method and system for hidden danger identification and risk assessment of 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. Due to 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 easi...

Problems solved by technology

The disadvantage of this method is that the risks of various underground pipelines are assessed, but the change of the coupling risk between the gas pipeline and the surrounding hazardous chemical enterprises is not considered. 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 hidden dangers
