气溶胶灭火

DSPA 浓缩气溶胶灭火。

DSPA 气溶胶发生器 由固体气溶胶形成化合物组成,装在一个非加压的红色罐子中,该罐子可对细分的固体颗粒进行气溶胶化:气溶胶灭火剂。气溶胶由固体气溶胶形成化合物的燃烧过程自生,由活化装置(也称为起动器)激活。

气溶胶

DSPA 气雾剂最初是作为哈龙和其他常规灭火剂的替代品而开发的。DSPA 气溶胶具有独特的安全性和有效性。DSPA 气溶胶的活性物质是固体微粒,可完全填满隔间,并在化学层面上攻击火灾的燃烧过程。结果,火焰立即被击落,能量从火中移除。

所需的灭火剂量明显少于 CO2、FM-200、Inergen 等常规灭火剂的用量。此外,DSPA 气溶胶可显著节省安装和维护费用:它不需要任何压力容器、歧管、喷嘴或管道作业。此外,与其他代理不同,DSPA是环保的。

灭火机制

与许多其他灭火剂不同,DSPA 气溶胶会干扰火中的连锁反应,使氧气水平保持不变。

“火势传播” 自由基(OH、H 和 O)是火势连锁反应的重要元素。DSPA Aerosol(主要)通过对火区内的这些自由基进行化学干扰来抑制火势,从而中断火势持续的连锁反应。

DSPA 气溶胶是一种由细分的固体颗粒(主要是钾颗粒)组成的灭火介质,通常直径约为 2 微米。当气溶胶进入火灾的燃烧区域时,会与燃烧过程中产生的火自由基(氢气、氧气和羟基)发生反应,从而灭火。小气溶胶颗粒为捕获这些自由基提供了较大的表面积,使其成为有效的灭火剂。
