A mobile dust collector for road and tunnel construction

Abstract

The invention provides a movable road and tunnel construction dust remover, and belongs to the field of road and bridge engineering. The movable road and tunnel construction dust remover comprises a bottom plate and a negative pressure draught fan, an adjusting plate is slidably arranged on the bottom plate, a dust removing box capable of filtering dirty air is fixed to the upper surface of the adjusting plate, and a filtering plate is vertically fixed into the cavity of the dust removing box. The filtering plate divides the cavity into a first cavity body and a second cavity body, the first cavity body communicates with a first square pipe, and a first square air suction pipe and a second square air suction pipe are hinged to the first square pipe. The second cavity body communicates witha second square pipe, and the other end of the second square pipe is arranged at an air inlet of the negative pressure draught fan. A sprinkling device capable of conducting water jetting is furtherarranged on the adjusting plate. The movable road and tunnel construction dust remover has the advantages of being simple in structure and low in construction cost, capable of flexibly adjusting the dust suction working face according to highway and tunnel construction environments, and meanwhile, capable of achieving dust removing efficiently on the basis of water saving.

Description

technical field [0001] The invention belongs to the field of road and bridge engineering, and relates to an industrial dust collector, in particular to a mobile road and tunnel construction dust collector. Background technique [0002] A large amount of dust and harmful gas will be generated during tunnel excavation and road repair construction. During tunnel construction, fresh air will be sent to the tunnel through an axial flow fan outside the opening and a ventilation pipe connected to the axial flow fan. Excavating the working face, and the dirty air in the tunnel is discharged out of the tunnel along the excavated tunnel body under the extrusion of the fresh air sent into the tunnel, so as to achieve the purpose of dust removal in the tunnel. However, in the actual construction process, the methods of dust removal through the tunnel ventilation system have problems such as low dust removal efficiency, affecting the subsequent construction of the tunnel, and poor dust r...

Problems solved by technology

[0004] However, the wet dedusting device used in the blasting and excavation of this tunnel is used for water curtain dedusting of dirty air, and the water is simply pumped from the water supply tank and sprayed three times with three electric water nozzles, and the sprayed water is returned from the overflow tank to the water supply tank. In addition, the three stages of progressive dust removal are all in the dust removal room, and the treatment is performed under the same water quality environment, which does not reflect the effect of the third stage dust removal at all, thus affecting the dust removal effect; at the same time, it cannot be based on actual roads and tunnels. According to the actual construction situation, adjust the vacuum work surface
