通风方式对化工车间火灾影响的实例分析

Study on the Influences of Ventilation Systems to Chemical Plant Fire

在分析化工企业火灾危险性的基础上,建立了化工车间火灾危险度分析数学模型。根据工程实际,分别对正常工业通风和火灾后事故通风工况进行了火灾危险度计算。计算结果表明事故通风及防排烟系统启动后,能有效的降低车间的火灾危险性等级。研究结果用于指导化工厂通风系统设计及提高消防安全管理水平。

Based on the fire risk in the chemical companies,a mathematical model of chemical plant fire hazard degree analysis was established.Quantitative analysis of fire hazard degree was achieved on the engineering practice,which included natural ventilation and emergency ventilation.When the emergency ventilation system and smoke control system acted in a fire,the fire hazard degree was reduced.The results of the study can be used as reference in ventilation system design and raising the level of the fire safety management to the chemical companies.
