含能气体发生剂对超细灭火剂施放效果影响的研究

Study on Dispersion Effect of Superfine Extinguishing Agent Dispersed by Different Energetic Gas Generating Agents

文章通过实验测定气体发生剂在密闭爆发器中的p-t曲线,观测灭火剂扩散云图、等效直径和外球壳破碎情况,研究了4种不同气体发生剂对超细灭火剂施放效果的影响。结果表明,气体发生剂的产气速率较快、产气量大时,灭火球外球壳碎片大小比较均匀一致,超细灭火剂在空间各方向的扩散分布也较均匀,空间扩散速度也越快。这些有利于超细灭火剂的全淹没灭火。

In this paper with the p-t curve of four gas generating agents gained by experiment in the dosed bomb, and the observation of dispersion cloud picture of superfine extinguishing agent, equivalent diameter and cracked shell of extinguish ball, dispersion effect of superfine extinguishing agent scattered by four energetic gas generating agents was studied. Results showed that the shell fragments size of extinguishing ball was uniform and the spread distribution of superfine extinguishing agent in space was even and fast when gas generation rate and production of gas generating agent was high. All these were beneficial to total flooding fire extinguishing by superfine extinguishing agent.
