Dust removal device and dust removal method

Abstract

The invention discloses a dust removal device and a dust removal method, the dust removal device comprises a movably arranged dust removal assembly and an air blowing device, the dust removal assembly comprises a dust removal box body used for filtering dust, a dust suction pipe connected to the air inlet end of the dust removal box body and an induced draft fan connected to the air outlet end of the dust removal box body; a second dust sensor for detecting the concentration of dust outside the dust suction pipe and a first dust sensor for detecting the concentration of dust in the dust suction pipe are arranged on the dust suction pipe; the dust removal box body and the induced draft fan are both configured to be started according to a detection result of the second dust sensor and closed according to the detection result of a first dust sensor; and the induced draft fan is provided with an induced draft fan outlet, and the induced draft fan outlet comprises a lateral outlet used for blowing air to one end of the blasting face and an axial outlet used for blowing air to one end away from the blasting face. When the device is used, the dust removal device does not need to be moved back and forth, inlet and outlet pipelines do not need to be connected, water is not needed, secondary pollution is avoided, the structure is simple, and the practicability is high.

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. [0003] In the prior art, th...
