持水冷却剂对油罐火灾高温罐壁冷却性能的研究

A Study on Cooling Performance of the Water-holding Coolant in a Tank Fire

设计并搭建了贴近火场实际的持水冷却剂冷却性能研究试验平台,通过与普通水对比,分别对不同流量及不同热辐射强度下持水冷却剂的冷却降温效果和节水能力进行了研究。研究结果表明,热辐射强度越大,持水冷却剂对受热板的冷却降温效果越好,节水效果越明显。但在热辐射强度不变的情况下,喷射流量越小,节水效果越明显。

An experimental platform, designed and built close to the actual the water coolant properties, is used to contrast with water without any additives in putting out a fire, and the research for the water coolant cooling effect and the ability with different flow and thermal radiation intensities is done. The results show that the greater the intensity of thermal radiation, the better for cooling effect of a water coolant heat plate, and the water - saving effect is more obvious. But when the heat radiation intensity remains unchanged, the smaller the injection flow rate, the more obvious the watersaving effect is.
