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.
