某博物馆典礼大厅烟气控制系统设计

摘要

某博物馆典礼大厅烟气控制系统采用自然排烟和自然补风,依据相关规范以及理论分析方法,研究烟气控制系统设计的有效性.研究发现无喷淋的典礼大厅发生4 MW的火灾、补风口面积为17.25m2时,自然排烟口面积不能满足典礼大厅自然排烟要求,应增大王25.4m2以上；建议在博物馆主入口处加设两个出入口,以增加自然补风面积.%The smoke control system of a ceremony hall of muse-um uses natural smoke exhaust and natural air supplement. The effectiveness of the smoke control system design based on relat-ed specifications and theoretical analysis method were studied. When the ceremony hall without spraying is on fire at the heat release rate of 4 MW. and natural air supplement vent area is 17. 25 m2, the natural smoke exhaust vent area can't meet the requirements of natural smoke exhaust of ceremony hall, and should be increased to 25. 4 m2. Adding two exit in the main entrance of museum was suggested to increase the natural air supplement area.
