消防专业论文-高层建筑火灾烟气的探测和控制研究.docxVIP

PAGE \* MERGEFORMAT IV 摘 要 在经济高速发展的今天，高层建筑是城市建筑规划设计发展的方向。但近年来高层建筑火灾的比例不断上升，造成的人员伤亡和财产损失也在逐年增加。据研究表明，在高层建筑火灾中,烟气是导致人员伤亡的主要因素,所以，必须对高层建筑中火灾烟气的探测和控制问题给予充分重视。 本文分析了烟气的组成，从毒害性、减光性和恐怖性介绍了其危害；在详细分析了高层建筑火灾中烟气扩散影响因素及离子式、光电感烟式等多种感烟探测器的工作原理、应用特点和应用范围的基础上，对目前高层建筑烟气探测及其普遍采用的各种防排烟方式进行了详细的分析，并结合火灾案例，对第三代消防车在高层火灾中排烟的优势及在实战中的应用进行了分析研究，给高层建筑火灾烟气探测及烟气控制提供一定的理论指导。 关键词:高层建筑； 烟气探测； 烟气控制 Abstract In the high-speed economic development today, high-rise building is the city construction planning and design development direction. But in recent years the proportion of high-rise building fires caused by rising, the casualties and property losses also increases year by year. According to the research indicates that, in high-rise building fire, smoke is causing casualties, so the main factors of high-rise building, must fire smoke in the detection and control problem give enough attention. This paper analyzes the composition of smoke from toxic, minus the light sex and terrorist introduced its harm; The detailed analysis of the smoke of high-rise building fires spread effect factors and ionic type, light inductance smoke detector such as type of variety of feeling smoke working principle, application characteristics and range of applications to present, on the basis of flue gas detection and high-rise building widely adopted various smoke way to carry on the detailed analysis, and combined with the third generation, fire cases of fire smoke ranked in high-rise fires the advantages and application in actual combat was analyzed for high-rise buildings, fire smoke detection and smoke control provide certain theoretical guidance. Keywords: high-rise building； smoke detection； smoke control. 目 录 TOC \o 1-3 \h \z \u HYPERLIN
