Abstract

The present invention relates to a tunnel air-exchange device, and more specifically to one in which: the air inside normal tunnels including tunnels through which vehicles run is cleaned and polluted internal tunnel air is expelled to the outside, to which end cold air, supplied to water tanks of different sizes provided in line at set intervals in the floor inside the tunnel, is used to ensure that the heavy soot and gases in the polluted hot air generated by vehicles, are sucked into the water tanks while the lighter foul air is discharged through chimneys by convection, thereby creating a pleasant tunnel environment by always maintaining clean air inside the tunnel; and which also extinguishes fires by spraying fire-extinguishing water during tunnel fires. Accordingly, the present invention combines a chimney effect with natural convection provided by the water tanks to exchange the air inside the tunnel and naturally expel polluted air, which is in contrast to exhaust fans of the prior art because there is no generation of noise or heat, and expenses can be reduced since there is no electrical consumption.

Description

technical field

[0001] The present invention relates to a tunnel ventilation device, in particular to a tunnel ventilation device adopting a natural ventilation method, which can purify the air inside a general tunnel including a vehicle passage tunnel, and at the same time discharge the polluted air inside the tunnel to Outside, a row of multiple water storage tanks of different sizes are set at certain intervals on the ground inside the tunnel. The cold air generated by the water storage tanks is supplied to the inside of the tunnel and meets the hot polluted air generated by vehicles to generate convection, making it heavier The soot and exhaust gas are absorbed by the water storage tank, and the light polluting gas is discharged to the outside through the chimney, so that the air inside the tunnel is always fresh, creating a comfortable tunnel environment, and when a fire breaks out in the tunnel, firefighting water can be sprayed to carry out Extinguishing.
