Description

technical field

[0001] The invention relates to a tunnel smoke exhaust method and a tunnel ventilation system with an independent smoke exhaust device. It is mainly used for ventilation in the tunnel and smoke exhaust in case of fire. Background technique

[0002] During the operation of road tunnels, vehicle emissions such as CO, NO X When the concentration of harmful exhaust gas and smoke exceeds a certain value, it will bring harm to the drivers and passengers, affecting their health and driving safety. Therefore, in order to ensure the hygienic standard of the air environment required for the normal operation of the tunnel, the tunnel should be ventilated. At the same time, there are always potential hazards caused by car fires or leakage of dangerous goods transportation during tunnel operation, and disaster prevention ventilation should be considered. Therefore, it is a major issue in tunnel ventilation and disaster prevention to not only ensure good air environment...
