Multi-station collaborative ventilation and smoke exhaust system and control method for short-distance dense stations

Abstract

The embodiment of the present invention provides a multi-station cooperative ventilation and smoke exhaust system and control method for short-distance dense stations, the system includes multiple interval tunnels and multiple station tunnels interlaced; multiple stations correspond to multiple station tunnels one-to-one Setting; the tunnel air shaft is arranged between at least two interval tunnels, and at least two stations are arranged between two adjacent tunnel air shafts; the heat exhaust air shaft and the smoke exhaust air shaft are arranged in each station tunnel; wherein, the tunnel The air shaft is connected to the section tunnel through the tunnel air duct; the heat exhaust air shaft is connected to the station tunnel through the hot air duct on the top of the tunnel rail and the hot air duct on the bottom of the tunnel rail; the smoke exhaust air shaft is connected to the station through the smoke exhaust duct in the public area. The invention can form a controllable air flow assembly in the tunnels of short-distance dense stations, realize ventilation and smoke exhaust in the tunnels of short-distance dense stations, and avoid the occurrence of large-scale disasters that are delayed and spread.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rail transit, and in particular to a multi-station cooperative ventilation and smoke exhaust system and a control method for short-distance dense stations. Background technique [0002] At present, my country's subway is in a period of unprecedented rapid development. Due to the limited space inside the city, most of the urban subway stations are underground stations. The operation safety of underground stations is a very prominent issue, and the most harmful is the casualties caused by the smoke and poisonous substances produced by combustion in subway stations and subway tunnels. [0003] Subway fires are more dangerous than ground building fires. Once a fire breaks out, the losses are often very serious. The main manifestations are: first, the underground station has insufficient oxygen supply, incomplete combustion, thick smoke, and a large amount of smoke; at the same time,...

Problems solved by technology

For this reason, the embodiment of the present invention proposes a multi-station collaborative ventilation and smoke exhaust system with short-distance dense stations to solve the defect that the tunnel smoke exhaust ventilation system in the prior art cannot be applied to short-distance dense station lines, and realize The simple design of the air conditioner and smoke prevention and exhaust system between the multi-stations of the dense station can form an airflow component that is easy to control in the tunnel of the short-distance dense station, realize the ventilation and smoke exhaust in the tunnel of the short-distance dense station, and avoid delays large-scale disasters spread

[0006] The embodiment of the present invention also proposes a control method for a multi-station cooperative ventilation and smoke exhaust system with short-distance dense stations to solve the defect that the tunnel smoke exhaust ventilation system in the prior art cannot be applied to short-distance dense station lines. According to different situations of fires in tunnels with densely spaced sites, targeted airflow control and ventilation and smoke exhaust measures are adopted to avoid the occurrence of large-scale disasters that are delayed and spread
