Description
Technical field
The utility model relates to a kind of fume extractors of exhibition building, belong to structural fire protection technical field.
Background technique
Show that flue gas is the arch-criminal that personnel death is caused in building fire according to fire statistics data, personnel die of sootiness
Account for large percentage, up to 80%, burnt in dead number, majority be also burnt after first poisoning is fallen in a swoon it is dead,
In the number that fire is died, most of to be that dense smoke is smoked choke the reaction of generation asphyxia and lead to death, Initial Stage of Fire take it is most quick,
Most effective smoke evacuation is that reduction fire is dead to maintain maximum, duration longest escape space and channel in the scene of a fire
The necessary condition for dying rate, by regulations for fire fighting, the marquis of the public transport such as subway, airport, railway station multiplies region and megastore, shadow
After institute, indoor amusement place should all be equipped with fire fume extractor, but fire occurs for these volumed space buildings, due to building height
Higher, after flue gas rises to certain altitude, flue gas disappears and switchs in a certain height with buoyancy caused by ambient air temperature difference
Negative value, cause flue gas to stop rising and to extending transversely so that the fume extractor of building top can not be implemented effectively to discharge fume, smoke evacuation
The effect is unsatisfactory, deposits the problems such as poor, the whole smoke exhaust efficiency of early stage flue gas inhibitory effect in a fire is low, existing fire-fighting row
Cigarette ventilation blower suction draught is small, and smoke discharging effect is poor, and smoke exhaust efficiency is low, while the flue gas being discharged is directly discharged into atmosphere, accelerates atmosphere dirty
Dye, therefore, it is necessary to be further improved.
Summary of the invention
