Chemical Enterprise Lightning Risk Assessment And Its Application

Chemical new material is a product of the latest science and technology development and the premise and basis of the latest science and technology development. Completely so to speak, without chemical new materials, there is no modernization of national defense and the formation and development of emerging industries, chemical new materials directly and indirectly impact on the development of national defense and national economy. But chemical industry because of its production process is multifarious, raw materials and products of toxic, harmful, explosive dangerous to shun, so the distribution of the chemical enterprise often concentrated in the suburb of remote, empty. In the suburbs of the empty, chemical equipment, factories and other buildings has become the commanding heights, particularly vulnerable to lightning strike. Lightning occurs in the atmosphere of physical phenomena, such as sound, light, electricity, etc. It brought great influence to human life. Throughout history, thunder great destructive power often cause building collapse, fires, damage to the equipment, and serious consequences such as casualties. Chemical enterprise of lightning protection design is according to the national standard GB50057lightning protection measures, but lightning accidents still happen, but also for after lightning accident may cause disasters and losses also lack forecast method. In order to further explore and improve the lightning protection design of chemical companies and need to lightning disaster risk assessment of chemical enterprises. How lightning disaster risk assessment of chemical companies, for the chemical industry enterprises to provide reliable reference for lightning protection design, has become a focus and urgent need to solve major problems.This article firstly introduces all kinds of lightning disaster risk assessment methods, and compare the advantages and disadvantages of these evaluation methods, to determine the comprehensive evaluation method for chemical companies; The thunder environment analysis, calculation and other lightning protection lightning risk value parameter calculation, etc., and also gives the application can be used to evaluate the results. Finally, a enterprise in chemical industry in the city area as an example, using the comprehensive evaluation method to the enterprise building lightning disaster risk assessment, and then according to the evaluation results targeted lightning protection design Suggestions are put forward.In this paper method of lightning disaster risk assessment and lightning protection design Suggestions for chemical enterprise buildings and chemical facilities design, lightning protection measures of the thunder disaster provides some references for the protection and management.
