摘要
从细水雾灭火技术的优越性出发,结合森林火灾中树木燃烧立体性的特点,提出了使用细水雾云团扑灭森林火灾的新思路。从细水雾灭火的降温作用、隔氧窒息作用以及浸润作用3个方面入手,通过理论分析,研究了细水雾云团对树木火灾的灭火效能,得到了理论公式,并提出了公式的修正方法。对比了球状、柱状细水雾云团的灭火效能,得出了在扑灭森林火灾中,柱状细水雾云团的效能高于球状细水雾云团的结论,可以为新型森林灭火装备的研制提供一定的理论基础。
Base on the advantages of the water mist extinguishing technology, combined with the three-dimensional distribution ofthe trees burning in the forest fire, we proposed to use water mist cloud to put out the forest fire. We studied the water mist fire extinguishing effects including cooling, oxygen insulation and infiltrating effect. We studied the fire extinguishing efficiency of water mist cloud, and put forward the theoretical formula and the correction method of formula. By comparing the extinguishing efficiency of spherical and cylindrical water mist cloud, the later extinguishing efficiency in forest fires is higher. The study results may provide a theoretical basis for further development of the new forest fire fighting equipments.
