泡沫连续供给技术研究

Study on the continuous foam supplying technology

针对大型油罐火灾灭火过程中的泡沫连续供给问题,将远程供水系统和泡沫比例混合器的特性相结合,设计泡沫连续供给系统。介绍系统设计思路,重点说明平衡比例混合系统的扩散管口设计和孔口处横截面积设计,并计算其泡沫连续供给可行性。可为相关消防设备的设计研发和消防部队扑救油罐火灾的战术方法提供参考。

Against the continuous foam supplying problem during the firefighting of large-scale oil tank fire accident, the features of remote water supply system and foam mixer were combined, to design the continuous foam supplying system. The design idea was introduced, and the diffusion nozzle design as well as the cross sectional area design at orifice of balanced proportional hybrid system was focused on. The feasibility of the continuous foam supply was calculated. The study can provide reference for related firefighting device design and oil tank fire accident firefighting tactics.
