Description

technical field

[0001] The invention relates to the technical field of tunnel dust removal, in particular to a dust removal device and a dust removal method. Background technique

[0002] A large amount of dust will be generated during the excavation of the tunnel, and the dust is usually discharged out of the tunnel by means of ventilation, and the dust will pollute the entire tunnel during the dust discharge process. At present, dry or wet dust collectors have been used in non-explosive excavation to collect and filter the dust generated during the excavation process in time, and discharge clean air, thereby avoiding the phenomenon of dust polluting the tunnel; in the tunnel excavated by blasting method At present, there is no case of using a dust collector to remove dust. As people's requirements for the working environment are getting higher and higher, the application of dust collectors in tunnels excavated by blasting will become a trend.
