Embodiment 1

[0022] tunnel ventilation systems such as Figure 1 to Figure 6 As shown, it includes a tunnel ventilation device arranged on the inner wall 1 of the tunnel. The tunnel ventilation device includes an air inlet device and an air outlet device. The air inlet device includes a casing 2, a filter plate 3 arranged above the casing 2, and a The blower fan 4 above the 3 and the filter plate 3 are evenly distributed with through holes 9, the housing 2 is cylindrical, and the inside is hollow to ensure the smooth flow of the air intake passage.

[0023] The air outlet device includes a bottom plate 5, a top plate 6 connected to the bottom plate 5, and an arc-shaped plate 7 connected to the top plate 6. The bottom plate 5, the top plate 6, and the arc-shaped plate 7 form a cavity 8 for ventilation. The housing 2 communicates with cavity 8.

[0024] Bottom plate 5 comprises side plate 51, the transverse plate 52 that links to each other with side plate 51 and the bent plate 53 that link...

Abstract

The invention relates to the technical field of tunnel ventilation and discloses a tunnel ventilation system. The tunnel ventilation system comprises a tunnel ventilation device, and the tunnel ventilation device comprises an air inlet device and an air outlet device, wherein the air outlet device comprises a shell, a filtering plate above the shell and a fan above the filtering plate; the air outlet device comprises a bottom plate, a top plate connected with the bottom plate and an arc plate connected with the top plate; the bottom plate, the top plate and the arc plate define a cavity for ventilation; and the shell is communicated with the cavity. Compared with the traditional mechanical ventilation mode, the tunnel ventilation system obviously improves the ventilation effect, increases the safety factor, reduces noise pollution, saves energy and is environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation, in particular to a tunnel ventilation system. Background technique [0002] A good air condition in the traffic tunnel is a necessary condition for driving safety. Ventilation is to reduce the concentration of harmful gases or pollutants in the tunnel and ensure the safety and comfort of driving. [0003] Common ventilation methods for existing tunnels are as follows: [0004] Natural ventilation: The so-called natural ventilation refers to the removal of harmful gases and smoke from the tunnel through the piston action of cars passing through the tunnel and the natural wind. The use of natural ventilation mode is limited by the traffic flow in the tunnel, and the instability and complexity of natural wind will greatly affect the airflow exchange in the tunnel. [0005] Longitudinal ventilation: The so-called longitudinal ventilation is a way to introduce fresh air from one opening a...
