摘要:
为探究风速、风向、喷射口径对喷射火作用下石化装置温升规律的影响,采用火灾动力学模拟(FDS)软件对喷射火作用下石化装置温升规律开展了系统的数值模拟研究。结果表明喷射口径小于0.15 m时,装置的温升速率随喷射口径的增大增速较快,喷射口径大于0.2 m时,装置的温升速率随喷射口径的增大增速减缓,石化装置的温升速率与喷射口径呈指数函数关系。风速和风向都会对石化装置的峰值温度和温升速率产生较大的影响,石化装置的温升速率随风速增大呈现一元三次函数的关系。风速增大时,装置峰值温度逐渐降低且降幅逐渐增大,风向与火焰夹角增大时,石化装置的峰值温度逐渐降低且降幅逐渐较小。研究建立了喷射火作用下石化装置温升定量计算公式,实现石化装置温度随喷射火作用时间变化的定量计算,可为安全管理与事故应急管理提供数据支撑。
Abstract:
To explore the influence of wind speed, wind direction, and jet diameter on the temperature rise of petrochemical equipment under the action of jet fire, this article uses fire dynamics simulation tool(FDS)software to conduct a systematic numerical simulation study on the temperature rise of petrochemical equipment under the action of jet fire. The results show that when the injection diameter is less than 0.15 m, the temperature rise rate of the device increases rapidly with the increase of the injection diameter.When the injection diameter is greater than 0.2 m, the temperature rise rate of the device slows down with the increase of the injection diameter. The temperature rise rate of the petrochemical device is exponentially related to the injection diameter. Both wind speed and direction have a significant impact on the peak temperature and temperature rise rate of petrochemical equipment. The temperature rise rate of petrochemical equipment exhibits a cubic function relationship with increasing wind speed. As the wind speed increases, the peak temperature of the device gradually decreases and the decrease amplitude gradually increases. As the angle between the wind direction and the flame increases, the peak temperature of the petrochemical device gradually decreases and the decrease amplitude gradually decreases. A quantitative calculation formula for temperature rise of petrochemical plants under the action of jet fire was established. This model enables quantitative calculation of the change in temperature of petrochemical equipment over time due to the effect of jet fire, providing data support for safety management and emergency response management.
