LPG储罐水喷雾防护技术研究进展

Research progress in water spray protection technology of LPG storage tank

对液化气储罐采取水喷雾保护措施的研究进展进行了归纳总结,概述了液化气储罐火灾特点。对储罐水喷雾的喷射强度、用水量及对热辐射削弱作用等的试验研究和数值模拟研究进行归纳,指出应开展立式圆罐和球形罐的水喷雾防护试验,模拟试验应考虑储罐、内部介质、火焰和水喷雾系统之间的耦合。分析现有研究中存在的问题和发展趋势,为以后的研究提出方向。

The research progress in water spray protection meas- ures of LPG storage tanks was sum up, the LPG storage tank fire characteristics was summarized. The water spray rate, wa- ter consumption and thermal radiation damping effect in the ex- perimental study and numerical simulation were introduced. It was suggested that taking water spray experiment on the verti- cal round tank and sphere tank, taking the coupling effect of tank, inner medium, fire and water spray in the numerical sim- ulation. The problems existing in the research and development were analyzed and research direction for the future was put for- ward.
