超声速喷气式清洁灭火技术

A Fire Extinguisher Using Supersonic Jet

摘要: 探索新型、环保的灭火技术，是消防领域研究的重要发展方向之一。本文利用物质在超声速条件下极难燃烧的原理，设计一种能喷射超声速气流的灭火装置，利用廉价和充足的环境大气作为气源，为抗争火灾提供新的手段。文中对该技术的原理、设计以及验证进行了论述。该类新型灭火装置，不易对贵重的燃烧物造成破坏，在缺水或某些不适合用现有灭火手段的场合可以发挥作用，而且与现有灭火手段配合使用，能够提高灭火效率，降低对水资源的消耗及对环境的污染。

Abstract: Exploring a novel and environmental technique for fire extinguishing is one of the important development of fire protection. In this manuscript, the theory that substance can hardly be burned under supersonic situation is adopted to design a supersonic jet fire extinguisher using the air as the working medium. This paper discussed the theory, design and validation. This device would not contaminate valuable burning substance and is useful in condition without or lack of water. Together with the existing devices, it can help to improve the efficiency and reduce the consuming of water.
