摘要: 针对干粉灭火剂会造成污染、清洗困难、可能造成设备损坏等问题，设计了一种可燃性粉尘环境用高压细水雾自动灭火系统。火焰传感器检测到可燃性粉尘燃烧火焰信号后，高压蓄能系统第一时间产生高压水并迅速形成高压细水雾，然后供水系统快速增压到工作压力，接替高压蓄能系统继续提供高压水并持续生成高压细水雾。测试结果表明，可燃性粉尘环境用高压细水雾自动灭火系统响应速度快，火焰传感器和控制器的平均响应时间分别为4 ms和12 ms；高压细水雾生成速度快，平均生成时间为96 ms，最长生成时间为100 ms；灭火及时有效，在高压细水雾作用于燃烧火焰1 s后，燃烧火焰基本被扑灭，燃烧火焰传播至距中心点火位置0.2 m左右停止了传播扩散，验证了该系统能够有效避免可燃性粉尘燃烧火焰的蔓延，防止可燃性粉尘火灾事故。Abstract: In view of problems that dry powder fire extinguishing agent will cause pollution, difficult cleaning and equipment damage, a high-pressure water mist automatic fire extinguishing system for flammable dust environment was designed. High-pressure energy storage system generates high-pressure water immediately and rapidly forms high-pressure water mist after flame sensor detects flame signal of flammable dust combustion, and then water supply system is quickly pressurized to working pressure, replaces high-pressure energy storage system to provide high-pressure water and continue to generate high-pressure water mist. The test results show that the high-pressure water mist automatic fire extinguishing system for flammable dust environment has fast response speed, average response time of flame sensor and controller is 4 ms and 12 ms respectively; high-pressure water mist generation is fast and average generation time is 96 ms, the longest generation time is 100 ms; the fire extinguishing is effective and timely, after the high-pressure water mist acts on combustion flame for 1 s, the combustion flame is basically extinguished, and the propagation and diffusion of combustion flame stops when propagates to about 0.2 m from the center ignition position. It is verified that the system can effectively avoid spread of flammable dust combustion flame and prevent flammable dust fire accidents.
