[0002] During the construction and use of tunnels, especially during the construction process, large areas of dust often appear. For example, during the finishing of prefabricated concrete parts and the grinding operations in the tunnel, this harsh dust environment is particularly obvious. The current treatment measure is to transport the dust outward over long distances through ventilation equipment. This method requires a lot of energy and the layout of long ventilation ducts, and the cost is high in actual use. Furthermore, during the use of tunnels, when encountering vehicle accidents, the leaked dangerous gases must be adsorbed during the treatment of some dangerous goods transport vehicles. The purpose is to reduce the impact of dangerous goods on the environment. However, most of the existing treatment methods are external dilution, which is diverted into the atmosphere through ventilation equipment and naturally absorbed by the atmosphere. This method pollutes the environment.
