【摘要】：为明确火探管式自动探火灭火装置对典型密闭空间铁路调度所大屏幕的灭火效能及灭火后的烟气毒性,采用火灾实体试验的方法,选用七氟丙烷和二氧化碳分别作为灭火介质,研究灭火过程的温度变化及灭火后的烟气浓度。研究结果表明:与二氧化碳相比,七氟丙烷灭火效果更为高效,且大屏幕空间温度下降速度更快;与二氧化碳相比,采用七氟丙烷后燃烧过程得到较好的抑制,且七氟丙烷灭火时有毒有害烟气浓度相对较少。
[Abstract]:In order to make clear the fire extinguishing efficiency and smoke toxicity after fire extinguishing of typical closed space railway dispatching station, the fire entity test method was adopted, and heptafluoropropane and carbon dioxide were used as fire extinguishing medium, respectively. The temperature change of fire extinguishing process and the smoke concentration after fire extinguishing were studied. The results show that: compared with carbon dioxide, heptafluoropropane is more effective in extinguishing fire, and the temperature of large screen space is decreasing more quickly, compared with carbon dioxide, the combustion process of heptafluoropropane is better suppressed. In addition, the concentration of toxic and harmful smoke is relatively low when sevofluropropane is extinguished.
