摘要:
基于液化石油气的特点,建立了有限空间内部发生泄漏扩散的物理模型,模拟了液化石油气泄漏扩散的过程,通过模拟结果分析其扩散规律,并对比当泄漏孔形状分别为正方形、圆形、三角形时液化石油气扩散过程的变化以及对所形成的的爆炸危险区域的影响。监测点1(0.8,0.3,0),点2(2.4,0.3,2.5),点3(0,0.3,1.5),点4(2,0.3,3)的浓度变化,找出报警器的最佳安放位置。结果表明:泄漏时间相同,丙烷的扩散范围从大到小依次为三角形孔口、圆形孔口、正方形孔口,爆炸危险区域也与泄漏孔形状有关,三角形孔口的危险区域范围最广,其次是圆形泄漏孔,正方形泄漏孔的范围最小,点1处的丙烷浓度增长幅度较大,浓度较高,可以更早达到报警浓度。
Abstract:
According to the characteristics of LPG, a physical model on leakage and diffusion of LPG in limited space was established. The leakage and diffusion process of LPG was simulated, and the diffusion laws were analyzed through the simulation results. The change in diffusion process of LPG and the influence on the formed explosion dangerous area when the leakage hole shape was square, circle and triangle respectively were compared. The concentration variation in point 1(0.8, 0.3, 0), point 2(2.4, 0.3, 2.5), point 3(0, 0.3, 1.5) and point 4(2, 0.3, 3) were monitored to find out the optimal arrangement position of alarm. The results showed that under the same leakage time, the diffusion ranges of propane in descending order were triangular hole, circular hole and square hole. The explosion dangerous area was also related to the leakage hole shape, the dangerous area of triangular hole had the largest range, followed by the circular hole, and that of square leakage hole was the smallest. The growth rate of propane concentration in point 1 was larger and the concentration was higher, so the alarm concentration could be reached earlier.
