【摘要】：当今时代,化工产品已经深入人们的日常生活和方方面面,不论个人还是国防工程,还是高科技,化工产品都得到广泛的使用;但是,目前,我国的化工企业的选址大都在分布在东南部以及沿海地区,而且相对集中,这些地区雨季较长,雷电活动比较频繁,地势比较平坦,高大生产装置、建筑物等成为制高点,容易遭受雷击。一旦发生化工企业雷击事故,其人员和财产损失不可忽视。目前,我国化工企业的防雷设计是主要依据《建筑物防雷设计规范》进行防雷措施的,但是雷击事故还是时有发生,而对于发生雷击事故后可能引起的损失程度缺乏科学预判和应急救援。为了进一步探索和完善我国化工企业的防雷设计施工,需要对现有的化工企业的防雷设施重新进行科学风险评估。如何对化工企业的雷击灾害风险进行评估,为化工企业的防雷设计施工提供行之有效的参考依据,已经成为且迫切需要解决的生产安全问题。本文首先介绍雷电危害和进行防雷风险评估意义;通过对比目前国内外对雷电灾害评估几种标准和方法,找出现有防雷风险评估的缺陷,从而提出在化工企业使用雷电灾害综合评估方法,即依据《建筑物电子信息系统防雷技术规范》(GB50343-2012)、《爆炸危险环境电力装置设计规范》(GB50058-2014)和《建筑物防雷设计规范》(GB50057-2010)为基础,确定防雷风险评估的风险因子和雷电环境因素等,经过定性分析与计算,得到防雷风险评估所需的风险值,从而解决了单独使用一种评估方法所带来局限性和片面性。最后,以本市一家化工企业为例,通过上述的防雷风险综合评估,为该企业的甲类仓库等7个场所的建筑物进行防雷风险评估分析与计算,利用防雷风险评估计算出的分险值对该企业的甲类仓库等7个场所逐一分析判断,是否需要进行防雷措施;在这基础上,为企业提出一个确实可行的防雷措施建议和施工方案。
[Abstract]:Nowadays, chemical products have been widely used in people's daily life and in all aspects, whether personal or national defense engineering or high-tech. However, at present, Most of the sites of chemical enterprises in China are located in the southeast and coastal areas, and they are relatively concentrated. In these areas, the rainy season is longer, the lightning activity is relatively frequent, the terrain is relatively flat, and tall production installations and buildings have become the commanding heights. It is easy to be struck by lightning. Once a lightning strike accident occurs in a chemical enterprise, the loss of its personnel and property should not be ignored. At present, the lightning protection design of chemical enterprises in China is mainly based on the Lightning Design Code for buildings. However, lightning accidents still occur from time to time, and there is a lack of scientific prediction and emergency rescue for the possible losses caused by lightning strikes. In order to further explore and improve the design and construction of lightning protection for chemical enterprises in China, It is necessary to re-carry out the scientific risk assessment of the existing lightning protection facilities in chemical enterprises. How to evaluate the lightning hazard risk of chemical enterprises and provide an effective reference basis for the lightning protection design and construction of chemical enterprises. This paper first introduces the significance of lightning hazard and lightning protection risk assessment, and compares several standards and methods of lightning disaster assessment at home and abroad. To find out the defects of lightning protection risk assessment, so as to put forward a comprehensive assessment method of lightning disaster in chemical enterprises. Based on the Technical Code for Lightning Protection of Building Electronic Information system (GB50343-2012N), the Design Code of Electric Power device for explosive Hazardous Environment (GB50058-2014) and the Code for Lightning Protection of buildings (GB50057-2010), the risk factors and lightning environmental factors for lightning protection risk assessment are determined. Through qualitative analysis and calculation, the risk value needed for lightning protection risk assessment is obtained, thus solving the limitation and one-sidedness brought about by using one evaluation method alone. Finally, taking a chemical enterprise in this city as an example, Through the comprehensive assessment of lightning protection risk mentioned above, the lightning risk assessment and calculation are carried out for the buildings in 7 places, such as the Class A warehouse of the enterprise. By using the risk value calculated by lightning protection risk assessment, the author analyzes and judges whether lightning protection measures are needed in seven places such as the Class A warehouse of the enterprise one by one, and on this basis, puts forward a feasible proposal for lightning protection measures and construction plan for the enterprise.
