Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology in tunnel construction, and in particular to a dust removal device for tunnel construction. Background Technology
[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels. The structure of a tunnel consists of two parts: the main structure and auxiliary equipment. The main structure comprises the tunnel body and portals, while auxiliary equipment includes passing bays, fire-fighting facilities, emergency communication systems, and drainage systems. Long tunnels also have specialized ventilation and lighting equipment. Tunnels generate a lot of dust during construction, which is inconvenient for workers. Therefore, dust removal devices are needed to remove dust from the air.
[0003] Existing dust removal devices generally use high-pressure water mist spraying for dust removal. However, the nozzles of high-pressure water mist spraying are usually set up in a relatively concentrated manner, which cannot reach the inside of the tunnel and results in poor dust removal effect. For example, in the publication number CN217119717U, the nozzles are set up in a relatively concentrated manner, which cannot effectively remove dust from the inside of the tunnel, resulting in poor dust removal effect and low dust removal efficiency.
