Description

Technical Field

[0001] The utility model relates to the technical field of tunnel dust removal, in particular to a dust removal device for a railway tunnel. Background Art

[0002] Since the train's air-conditioning and ventilation system cannot completely filter out dust, the carriage will feel dusty. When the train is running, fine dust is generated. In the relatively closed environment of the tunnel, the fine dust will float for a long time.

[0003] The prior art discloses a dust removal device for railway tunnels with the announcement number CN217068235U, which includes a main body shell, support blocks fixedly installed at the four corners of the main body shell base, an air inlet pipe fixedly installed on the upper side of one side of the main body shell, a negative pressure fan embedded in the other side of the main body shell, filters installed on both sides of the negative pressure fan, a through groove opened on the front surface of the main body shell, and a collection box slidingly installed inside the through groove. The above device drives the screw to rotate by starting the servo motor and the water pump. Since the screw is threadedly connected to the slider, the cleaning rod on the slider is driven to move up and down, which facilitates the preliminary cleaning of the main body shell surface. At the same time, the water inside the guide tube is sent to the second nozzle for spraying through the telescopic tube, thereby improving the overall cleaning effect. This effectively achieves the effect of automatic cleaning, so that the inside of the main body shell is always clean, which is convenient for users to use.

[0004] The above-mentioned dust removal device of the railway tunnel sends the water inside the guide tube to the second nozzle for spraying through the telescopic tube, thereby improving the overall cleaning effect.
