摘要: 针对油罐密封圈火灾的安全问题, 以1 0×1 0 4 m3浮顶原油储罐为研究对象, 采用 V i s u a lC++6. 0编
程软件计算了密封圈火灾的模拟区域, 应用F LUENT流体模拟软件对着火油罐辐射的热量分布进行了模拟, 进而
确定了距着火油罐距离不同时的辐射热量及其对人及设备的伤害程度。研究结果表明, 在无风的稳态池火灾条件
下, 着火油罐向周围均匀地辐射热量, 随着距着火油罐距离的增加, 接收点接收到的辐射热迅速减小; 当辐射热量由
3 7. 5kW/m2降至1 2. 5kW/m2时, 对人及设备的伤害程度大大降低; 如果不考虑风速及临近油罐的喷淋带来的影响,
临近油罐的安全距离应为3 5. 5m。

关键词: 大型储罐, 密封圈火灾, 伤害范围, 热辐射, 安全距离

Abstract: With respect to the security issue of storage tanks’ seal ring fire, by taking 10×104 m3 crude oil tank as the research object, using Visual C++ 6.0 programming software to calculate the model domain of seal ring fire and FLUENT programming software, the thermal radiation of burning storage tank was simulated, which could get the thermal radiation in different distance from the burning storage tank and the damage to people and devices in different thermal radiation. The results showed that the burning storage tank radiated heat equably to all around under the condition of breezeless and steady pool fire. With the distance from the burning storage tank increasing, the thermal radiation decreased. When the thermal radiation decreased from 37.5 kW/m2 decreasing to 12.5 kW/m2, the damage to people and devices greatly decreased. Without considering the influence of wind speed and the adjoining storage tanks’ spraying, the safe distance of adjoining storage tank was 35.5 m.

Key words: Large storage tanks, Seal ring fire, Damage scope, Thermal radiation, Safe distance
