【摘要】:為研究自動(dòng)噴水滅火技術(shù)對高大空間建筑火災(zāi)控火性能的影響,按照高大空間公共建筑和廠房的實(shí)際火災(zāi)場景,開展自動(dòng)噴水滅火技術(shù)全尺寸火災(zāi)試驗(yàn)和數(shù)值模擬計(jì)算。選定的噴頭流量系數(shù)為K-161,安裝高度為18 m,噴水強(qiáng)度分別為20和25 L/(min·m2)。試驗(yàn)結(jié)果顯示,在該火災(zāi)場景中,第1只噴頭在點(diǎn)火后3~4 min動(dòng)作,噴頭開放數(shù)為3~4只即能成功控制火勢的增長和蔓延,頂板下的最高溫度為120℃,距火災(zāi)試驗(yàn)?zāi)P?.4 m處的最高溫度為20℃。數(shù)值模擬計(jì)算與實(shí)體火試驗(yàn)結(jié)論基本一致,說明高大空間建筑采用自動(dòng)噴水滅火系統(tǒng),能達(dá)到很好的控火甚至是滅火效果。
