AI Technical Summary

Technical Problem

Existing dust suppression devices suffer from uneven spraying range when facing external wind forces, especially insufficient resistance to lateral and longitudinal winds, resulting in poor dust suppression performance.

Method used

It adopts an auxiliary airflow guiding mechanism and a horizontal adjustment mechanism. Through the design of downwind and upwind inlets, combined with a rotating block and a horizontal adjustment mechanism, the direction of the spray head and the airflow direction can be adjusted to enhance the adaptability to different wind directions. It also guides and adsorbs the water mist or dust through the external air outlet.

Benefits of technology

It improves the stability and range of water mist coverage, enhances the adaptability to different wind forces, ensures the environmental dust reduction effect in the construction area, and reduces the impact of water mist and dust on the external environment.

Abstract

This invention relates to the field of air pollution control and dust suppression technology, and discloses an environmentally friendly dust suppression device for highway pavement construction. The device includes a barrier and a mounting base. The mounting base is installed on the top of the barrier, and a plurality of spray heads are arranged on the top of the mounting base, facing the inner side of the barrier. A diversion pipe is provided outside the plurality of spray heads for supplying water to them. An auxiliary flow guiding mechanism is provided outside the plurality of spray heads, including a downwind outlet and an upwind outlet located on the upper and lower sides of the spray heads. Through the combined use of the auxiliary flow guiding mechanism and the horizontal adjustment mechanism, the stability of the water mist coverage is effectively increased, and the coverage range of the water mist can be adapted to different wind conditions, improving the coverage effect of the water mist. This effectively enhances the environmental dust suppression effect of the device during road construction, ensures construction safety, and effectively reduces the impact of the sprayed water mist and dust generated during internal construction on the external environment of the barrier.
