Exhaust airway-free purifying exhaust structure for road tunnel

Abstract

The invention discloses a purifying exhaust structure for a road tunnel, which comprises a draught opening, a draught pipe communicated with the draught opening, a tunnel polluted air purifying device connected with the draught pipe, a fan connected with the tunnel polluted air purifying device, an exhaust pipe connected with the fan, and air exhaust opening communicated with the exhaust pipe. The structure overcomes the drawbacks of an exhaust airway and exhaust tower scheme and a tunnel opening direct polluted air exhaust scheme, radically solves the problem that the sites of the exhaust airway and exhaust tower for the road tunnel are difficult to select and the problem that the exhaust airway and exhaust tower for the road tunnel are unfavorable for landscape and greatly reduces the pollution of the tunnel to the atmospheric environment.

Description

technical field [0001] The invention relates to a tunnel air discharge system, in particular to a polluted air purification discharge system in a road tunnel. Background technique [0002] With the development of economy, urban traffic contradictions are becoming more and more prominent, and the demand for inter-city traffic is increasing. Road tunnels have become a favorable means to solve traffic contradictions and an important part of transportation facilities. However, since the tunnels are fully enclosed structures, the air in the tunnels contains dust particles (PM), carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NO X ) and other pollutants. The particulate matter PM in the tunnel air can cause chromosomal aberrations in blood lymphocytes; because CO combines with human hemoglobin, it directly reduces the amount of oxygen in the blood, causing headaches, drowsiness, and a sense of loss of balance. When the concentration is too high, it will lead to death...

AI Technical Summary

Problems solved by technology

This set of equipment is connected with the main tunnel, air duct, air shaft, and wind tower, which satisfies the requirements of air pollution control in tunnels, but does not solve the problem that road tunnels need to be equipped with exhaust shafts and exhaust towers to remove air from the tunnel. air pollution problem

[0008] To sum up, in the prior art, under the condition that the environment does not allow the direct discharge of polluted air at the entrance of the road tunnel, it is still necessary to set up exhaust shafts and exhaust towers to remove the polluted air in the tunnel, which will bring great harm to the atmospheric environment and landscape. Negative Effects

Therefore, there is an urgent need to develop a road tunnel without exhaust shafts and exhaust towers to purify and exhaust air structures, which can overcome the shortcomings of existing tunnels with exhaust shafts, exhaust towers, and tunnels that directly discharge polluted air.
