摘　　要：在化工企业中为满足生产需求,部分会配套设置危险化学品储罐区,用于化工原料的储存和使用。危险化学品储罐区安全风险等级属于较大及以上风险,存在的事故类型主要包含火灾、其他爆炸、中毒和窒息。储罐区当储存的危险化学品等于或超过临界量时,可构成危险化学品重大危险源,因其存在的固有风险越高,事故状态下造成的后果越严重。文章模拟N,N-二甲基甲酰胺储罐区物料泄漏,利用池火灾和蒸气云爆炸伤害模型分析,可以预知火灾状态下不同热辐射强度对周围设备、人员造成的影响,以及爆炸形成的伤害、破坏半径范围,为企业事故预防和应急救援提供参考。In order to meet production needs,some chemical enterprises will set up hazardous chemical storage tank areas for the storage and use of chemical raw materials.The safety risk level of the hazardous chemical storage tank area is relatively high or above,and the types of accidents that exist mainly include fire,other explosions,poisoning,and suffocation.When the hazardous chemicals stored in the storage tank area reach or exceed the critical amount,it can constitute a major hazard source of hazardous chemicals,as the higher the inherent risk,the more serious the consequences caused by the accident.This paper simulates material leakage in N,N-dimethylformamide storage tank area and analyzes the impact of different thermal radiation intensities on surrounding equipment and personnel under fire conditions using pool fire and vapor cloud explosion injury models.It can predict the range of injuries and damage radius caused by explosions,providing reference for enterprise accident prevention and emergency rescue.
