Subway station atrium fire disaster smoke exhaust system and method based on electric ceiling screens

Abstract

The invention provides a subway station atrium fire smoke exhaust system and method based on an electric ceiling screens. The smoke exhaust system comprises a platform layer and a station hall layer, wherein the platform layer is located underground, the station hall layer is located on the ground, a through atrium area is arranged in the middles of a public area of the platform layer and a public area of the station hall layer, smoke exhaust ports are formed in the top of the public area of the station hall layer, an atrium smoke exhaust port is formed in the top of the atrium area, outside the atrium area, telescopic electric ceiling screens are arranged at the top of the public area of the station hall layer, and air supply outlets are further formed in the top of the public area of the platform layer. According to the control method, according to different conditions, air outlets, air supply outlets and the ceiling screens of the public area of the platform layer and the public area of the station hall layer are selectively opened to be tightly matched with smoke outlets of the atrium, so that the smoke exhaust effect is optimized, and better evacuation conditions are provided for personnel in the station.

Description

technical field [0001] The invention relates to the technical field of fire ventilation and smoke exhaust, in particular to a fire smoke exhaust system and method for an atrium subway station based on an electric smoke-shielding vertical wall. Background technique [0002] At present, subway stations are densely populated places. Once a fire breaks out in the public area of ​​the subway station, and the fire smoke cannot be discharged in a timely and effective manner to control the fire, it is very easy to cause fatal accidents; especially for the atrium of a semi-underground subway station. In the event of a fire, it is more difficult to evacuate people in the public area of ​​the platform, and it is more difficult to discharge toxic and harmful smoke. [0003] In order to solve the above problems, the current subway underground station projects are designed with a ventilation and smoke exhaust system, which is used to timely and effectively discharge the fire smoke in the ...

AI Technical Summary

Problems solved by technology

[0004] However, most of the ventilation and smoke exhaust systems in public areas of semi-underground subway stations in the prior art are installed in non-atrium areas, lacking targeted countermeasures for fires in the atrium area, and it is difficult to prevent the fire smoke in the atrium area from spreading to the platform Or the public area of ​​the station hall, which will adversely affect the evacuation of personnel
