摘 要:隨著社會經(jīng)濟的發(fā)展、城市人口的增長，人類不斷向高層及地下拓展著自己的生存空間。但是，這兩類特殊建筑，特別是地下建筑一旦發(fā)生火災，由于建造上的特點與地面建筑有很大的差異，形成火災后不利于人員安全疏散和火災撲救，容易造成嚴重的人員傷亡和財產(chǎn)損失。而火災的煙氣更是危害人員生命的重要因素。但是現(xiàn)在的設計人員在進行消防設計時，卻往往只注重了建筑、給排水和電氣的消防設計，卻忽略了防排煙的設計。 直到近二、三十年來，防煙排煙的問題才開始為各國建筑設計和消防工作者所關注，并且建筑的防排煙設計已成為通風工程的一個分支而問世，也可稱之為建筑物發(fā)生火災條件下的通風工程，即防排煙工程。 本文首先對我國城市的火災現(xiàn)狀作了簡介，對火災中煙氣的危害性和防排煙工程的地位和作用進行了說明；其次對防排煙系統(tǒng)的設計要求進行了說明，包括防排煙區(qū)的劃分、防煙設計和排煙設計；而后給出了防排煙系統(tǒng)的設計計算，包括防煙系統(tǒng)設計計算和排煙系統(tǒng)設計計算；然后詳細介紹了防排煙系統(tǒng)的設備及附件，包括風機、管道、氣體的進出口、閥門、防火隔煙裝置等；最后介紹了防排煙系統(tǒng)的施工。 關鍵詞：地下室，火災，消防設計，防排煙
ABSTRACT:With the increase of city population and the development of socio-economy, mankind unceasing to high-rise and underground extend own vivo sphere. But two kinds of this are special to construct, especially underground building once occurring fire, its characteristic and ground building that built have great discrepancy, after forming fire disadvantage in people safety evacuate with fire put out a fire to save life and property, cause serious personal casualties and property loss easily. And the smoke spirit of a fire is also a important factor of endanger the personnel life. But now, while the designs carry on the fire design, usually paid attention to the design for the fire of the building, the drain and electricity, and neglected to the design of smoke control system. Until recent two or three decades, smoke exhaust problems was cared by the building designers and the fire workers from all the countries, and the design of smoke control system has become a branch of ventilation engineering, also called ventilation engineering of building fire conditions, namely smoke control engineering. In this paper, the fire of our city is introduced briefly, and explained the harmfulness of fire smoke and the status of smoke control engineering. Then explained the design requirements of smoke control system, including the partition of smoke control, smoke protection design and smoke extraction design. Then gave the calculation of the smoke control system, including smoke protection system calculation and smoke extraction system calculation. Then detailed the equipments and accessories of smoke control system, including draught fan, pipeline, exits and entrances of gas, valve, equipment of fire protection and smoke prevention etc. Finally introduced the construction of smoke control system.
