Efficient dust removal device used after tunnel construction

Abstract

An efficient dust removal device used after tunnel construction comprises a walking device, the top of the walking device is provided with a barrel with an opening in one side, the bottom of the barrel is provided with a plurality of air outlet holes, a dust suction device is arranged in the barrel close to the opening end, spraying equipment is arranged at the position, away from the opening end, in the barrel, and a dust settling and filtering device is arranged on the side, away from the opening of the barrel, of the spraying equipment. A purified water collecting part and a dust collecting part are respectively arranged on the lower side of the barrel and can respectively collect purified water and dust separated by the dust settling and filtering device, and a water pumping device is arranged in the purified water collecting part. Flying dust is thoroughly removed through multiple times of step-by-step flying dust settling treatment, turbid air is prevented from damaging the body health of workers, meanwhile, wet dust and purified water can be separated, the wet dust is independently collected and conveyed, the purified water can be reused for dust falling, the problem that water cannot be continuously supplied due to the fact that the tunnel is long is solved, the problem that water is accumulated in the tunnel due to water sprinkling is avoided, and meanwhile waste of water resources is reduced.

Description

technical field [0001] The invention belongs to the field of tunnel dust removal devices, in particular to a high-efficiency dust removal device after tunnel construction. Background technique [0002] Most of the existing tunnel dust removal equipment is pipeline-type dust removal. Due to the long length of the tunnel, it is difficult to lay the pipeline, and because the pipeline is long, it is prone to damage, which increases the difficulty of maintenance, and the pipeline-type dust removal equipment is difficult to move. It is beneficial to carry out complete dust removal treatment on the tunnel, but if water spraying and dust reduction are used, firstly, the water consumption will be huge, and it is difficult to sustain a large amount of water supply in the tunnel, and water spraying and dust reduction will consume a large amount of water resources; Water will increase the difficulty of subsequent construction, so a high-efficiency dust removal device for tunnel construc...

Problems solved by technology

[0002] Most of the existing tunnel dust removal equipment is pipeline-type dust removal. Due to the long length of the tunnel, it is difficult to lay the pipeline, and because the pipeline is long, it is prone to damage, which increases the difficulty of maintenance, and the pipeline-type dust removal equipment is difficult to move. It is beneficial to carry out complete dust removal treatment on the tunnel, but if water spraying and dust reduction are used, firstly, the water consumption will be huge, and it is difficult to sustain a large amount of water supply in the tunnel, and water spraying and dust reduction will consume a large amount of water resources; Therefore, a high-efficiency dust removal device for tunnel construction is specially designed for the above defects.
