摘要:
根据避难硐室气幕阻隔系统的防护功能,确定该系统由供气装置、散气装置和启闭装置组成;根据射流理论和对比试验确定气幕系统最佳孔径为1.2mm,最佳孔间距为40mm;通过SPSS方法建立模型,确定气幕系统以衰减距离x为变量的气体衰减函数;根据孔径、孔距及幕帘尺寸,计算确定气幕防护系统的最小供风量为1.61×10-3m3/s;通过模拟密闭空间阻隔性能测试,确定气幕系统的最大阻隔效率可达90%以上,同时阻隔效率随着二氧化碳初始浓度的增加而降低。
Abstract:
The research determines the system is composed of air supplying device,air diffuser and switch according to the protection function of the air curtain system of refuge haven.The best pore diameter of the air curtain is 1.2mm and the best hole spacing is 40mm according to the theoretical calculation and comparison test.The research determines the air attenuation function of distance x by establishing SPSS model.The minimum oxygen supplying quantity of the system is 1.61×10-3m3/s which is calculated according to the best pore diameter,the best hole spacing and the curtain size.The maximum barrier efficiency can reach more than 90% and the barrier efficiency decreases as the initial concentration of carbon dioxide increases,which is proved by barrier property test.
