簧片式水喷雾灭火技术具有压头.射程、雾滴和用水量的综合性能优势.本文作了簧片流体动力的理论分析,簧片振动雾化的相似准则分析,气雾柱的两相流径迹估算和气雾柱的灭火动力学估算.查明了作用在簧片上的升力,质量附加力和激振力,查明了影响雾滴大小的影响因素关系.查明了雾滴大小对灭火的影响等,为装置系列发展和优化设计途径提供了科学依据.
Reed water spray fire extinguishing technology has the pressure head, the comprehensive performance advantages of range, droplet and water consumption.This paper made a reed hydrodynamic theoretical analysis, reed vibration atomization of similar criteria analysis, aerosol column two phase Flow path estimation and aerosol column fire extinguishing kinetic estimation.The lift force, mass additional force and exciting force acting on the reed were identified, and the relationship between the influencing factors of the droplet size was identified.The size of the droplet pair The impact of fire, etc., for the installation of a series of ways to optimize the design and provide a scientific basis.
