喷射火作用下石化装置热响应规律数值模拟研究
Numerical simulation research on the thermal response law of petrochemical plants under the action of jet fire
摘要
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 diame-ter 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 pet-rochemical 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 in-creasing wind speed.As the wind speed increases,the peak temperature of the device gradually de-creases 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 de-crease amplitude gradually decreases.A quantitative calculation formula for temperature rise of petro-chemical 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,provi-ding data support for safety management and emergency response management.关键词
