Problems solved by technology

If multiple pollutants (PM, CO, NOx, HC, etc.) purification systems are used, there is no way to determine the number, scale, type of purification equipment and distribution of the system.
[0008] In addition, a purification system for various pollutants (PM, CO, NOx, HC, etc.) can be arranged inside the tunnel so that the concentration of pollutants at the exit of the tunnel can reach or approach the standard of the outdoor atmospheric environment. There will be no corresponding method to determine the number, scale, type and distribution of purification equipment of the system
[0009] To sum up, the existing road tunnels, regardless of the length of the tunnel, have not installed a purification system using multiple pollutants (PM, CO, NOx, HC, etc.) General methods of equipment types and layout

Embodiment Construction

[0065] The road tunnel of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0066] In the embodiment, a purification ventilation system with a draft ratio r≤0.5 is adopted, the distance between the mechanical air inlet 2 and the mechanical discharge outlet 7 is l=0m, and the slope of each point of the tunnel is 0; each purification ventilation system r is the same, and each pollution Each of the things i The S1 of the purification and ventilation system of each pollutant i is different, and the number n of the purification and ventilation systems of each pollutant i is different, then at least n i The purification ventilation system of group pollutant i is obtained by the following formula at vehicle speed V k The minimum group number n of the purification system for the lower pollutant i i value:

[0067] n i = B iS ...

Abstract

The invention discloses a group count determining and stationing method of a pollutant purification ventilation system for a road tunnel. In the group count determining and stationing method, a group count N and an interval Sj of the pollutant purification ventilation system set as required are obtained by calculating through a formula so that tunnel air pollutant concentration can meet a control standard of the tunnel air pollutant concentration or air externally exhausted from the tunnel achieves an environmental standard of an air pollutant.

Description

technical field [0001] The invention relates to road tunnels, in particular to the field of road tunnel air purification. Background technique [0002] With the development of economy, urban traffic contradictions are becoming more and more prominent, and the demand for inter-city transportation is also increasing. Road tunnels have become a favorable means to solve traffic contradictions and an important part of transportation facilities. According to traffic needs, each region often needs to set up expressway system to communicate. The common way to achieve communication is to adopt the form of elevated bridge road, which brings problems of urban landscape, noise, and large amount of construction and demolition. In order to overcome its shortcomings, it is necessary to adopt the form of a road tunnel. For tunnels such as crossing mountains, great rivers, rivers, straits, and sea crossings, the crossing distance is relatively long, so it is necessary to build long road tu...
