【摘要】：為明確火探管式自動(dòng)探火滅火裝置對(duì)典型密閉空間鐵路調(diào)度所大屏幕的滅火效能及滅火后的煙氣毒性,采用火災(zāi)實(shí)體試驗(yàn)的方法,選用七氟丙烷和二氧化碳分別作為滅火介質(zhì),研究滅火過程的溫度變化及滅火后的煙氣濃度。研究結(jié)果表明:與二氧化碳相比,七氟丙烷滅火效果更為高效,且大屏幕空間溫度下降速度更快;與二氧化碳相比,采用七氟丙烷后燃燒過程得到較好的抑制,且七氟丙烷滅火時(shí)有毒有害煙氣濃度相對(duì)較少。
[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.
