Research On Regional Cooperative Emergency Rescue Strategy In Chemical Industry Park Based On Scenario-Response

The intensification of enterprises,the large-scale equipment,and the complexity of associations in chemical parks have exacerbated the threat of catastrophic accidents.A failure of a certain link will often lead to chain accidents in adjacent process units or even the entire system,causing catastrophic accidents.Emergency rescue is the last key link in controlling risks in the chemical park.Effective emergency response measures can control the development of the accident at the initial stage of the accident and reduce the consequences of the accident.In order to strengthen the emergency rescue capabilities of the chemical park and reduce the casualties and property losses caused by the accident,domestic and foreign researchers have carried out a series of research work.However,there are still many shortcomings in the emergency rescue work of the chemical park at this stage,such as the lack of science and comprehensive analysis of accident scenarios in emergency handling of hazardous chemicals,resulting in poor operability of the emergency response strategies formulated.And in emergencies,the efficiency of emergency resource deployment is not high.And there is a lack of research on the synergy of emergency rescue systems in chemical parks.In order to make up for the shortage of the existing research on emergency rescue in chemical park,to solve the problems such as the lack of pertinence of emergency response strategy,the inefficient allocation of emergency resources and the lack of systematic cooperation in emergency rescue,this paper carried out scenario-response-based chemical park regional collaborative emergency rescue strategy research.The main research contents are as follows.(1)Based on the regional coordination theory,emergency management theory,and the analysis of the need for regional coordination of emergency rescue in chemical parks,multilevel regional coordinated emergency rescue strategy was proposed in this paper,including plant-level coordination,park coordination,and regional coordination.Then the method of determining the park coordination and regional cooperative emergency rescue area were established.(2)Research on accident scenario construction based on leakage unit.By fusing multisource heterogeneous data,the leakage unit partition method was constructed;The calculation models of the leakage rate and the maximum leakage of the leakage unit under different aperture were given,and the initial accident scene and the influence range of the accident consequence were determined by numerical simulation;Finally,considering the domino effect,the final accident scene construction method was determined.(3)Research on emergency resource demand of chemical industry park based on "scenario response".Based on the characteristics and injury forms of the accident,combined with the priority of emergency materials,the matching model of emergency materials for fire,explosion and poison leakage accidents were established.Then,based on the mapping relationship between accident scenarios and emergency resources,the calculation models of fire,explosion,poison leakage and diffusion core emergency resources and common characteristic emergency resources under domino effect accident scenarios were constructed,so as to determine the demand type and quantity of emergency resources under typical accident scenarios.(4)Research on regional collaborative scheduling scheme of chemical industry park.The principle,process and emergency response level of regional collaborative scheduling were established.Taking the shortest emergency scheduling time and the maximum collaborative degree as the objective function,the optimization model of regional collaborative scheduling of emergency resources in chemical industry park was constructed.The particle swarm optimization algorithm was used to solve the problem.Finally,the regional collaborative scheduling scheme of emergency resources in chemical industry park was obtained.(5)Design and development of emergency linkage command system in chemical industry park.Based on the analysis of functional requirements,the overall structure of the system was designed.With Windows 2000 as the operating system,visual studio as the development tool,C# as the development language and SQL server as the database,the emergency linkage command system based on scene database,resource database and response database was developed by using B / S structure,so as to realize "scene based response".
