Problems solved by technology

For longer urban tunnels, there is another traditional exhaust method, which is to set up a fan room at the exit of the tunnel to discharge the polluted air in the tunnel out of the tunnel hole. The polluted air is discharged outside the tunnel, which intensifies the pollution of the air outside the tunnel

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see Figure 1-2 , the present invention provides a technical solution: a wind tower type air purification system for urban tunnels, including a driving tunnel 1, an air purification duct 22 and a wind tower 13, such as figure 1 As shown, the air purification duct 22 is located at the upper end of the driving track 1, and the air purification duct 22 extends to the length direction of the tunnel, thereby covering the entire tunnel. For split-type two-way...

Abstract

The invention discloses a city tunnel wind tower type air purification system. The city tunnel wind tower type air purification system comprises a vehicular tunnel, an air purification wind duct and awind tower; the air purification wind duct is positioned at the upper end of the vehicular tunnel; the wind tower is positioned at the upper end of the air purification wind duct; and the wind towercommunicates with the air purification wind duct; an axial flow fan is arranged in the wind tower; the axial flow fan and the air purification wind duct communicate with each other through a flow collector; an air exhaust outlet is formed in the side wall of the wind tower; and a filter, a electrostatic dust collection unit and a denitrification device are arranged in the air purification wind duct in sequence. According to the city tunnel wind tower type air purification system, as the axial flow fan is arranged in the air purification wind duct, air in a tunnel is sucked out from the air purification wind duct; by arranging the electrostatic dust collection unit and the denitrification device in the air purification wind duct, the air is exhausted out of the tunnel after being purified so as to solve the problem that a traditional method only exhausts polluted air in the tunnel out of the tunnel to intensify air pollution degree outside the tunnel.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an urban tunnel wind tower air purification system. Background technique [0002] Urban tunnel is the main component of urban three-dimensional traffic. The main structures of urban tunnels include shield structure, immersed tube (buried tube) structure or excavation structure. The tunnel with shield structure or immersed tube structure has a relatively deep buried depth; the buried depth of tunnel with excavated structure is extremely shallow, and the outer top of the tunnel Usually set urban green areas or light buildings. The traffic flow of vehicles in urban tunnels is large, and the vehicles are in a slow-moving state for a long time, especially during peak traffic hours, when the vehicles in the tunnels will be idling, the air flow and concentration of polluted air in the tunnels are much greater than the ambient air outside the tunnels The emission of polluted a...
