便携式热气溶胶灭火器在家用汽车上的应用

Application of portable pyrosol fire extinguisher to family cars

随着人们安全意识的提高,车用灭火器已成为一种必备设施,然而传统干粉灭火器需对准着火部位喷射灭火,掀开汽车引擎盖时窜出的火焰会造成灭火人员被烧伤.为解决这一问题,提出一种在不打开汽车引擎盖情况下用气体灭火器实现灭火的方法.通过分析热气溶胶优缺点及克服其缺陷的方法,阐述了化学冷却剂的优点,并用实验进行了验证.实验结果表明配合使用化学冷却剂,热气溶胶灭火器喷口温度明显降低,灭火能力大为提高,对汽车引擎火有很好的灭火效果.

With the improvement of people＇s security awareness, the vehicle fire extinguisher has become a kind of necessary facility. However, a person who uses the dry power fire extinguisher may be burned by the fire when o- pening the engine hood. In order to solve this problem, a method of extinguishing fire by using air fire extinguisher in the case of not opening the hood was proposed. The authors analyzed the merits, disadvantages of pyrosol, pro- posed the method for overcoming its defects, and described the merits of chemical coolant. The experimental results show that, with the assistance of chemical coolant, the temperature of the nozzle of the pyrosol fire extinguisher is lowered apparently, and the fire extinguishing ability is greatly improved. Therefore, the effect for extinguishing fire in the engine of a car is excellent.
