Description

Technical Field

[0001] The invention relates to the technical field of dust removal and environmental protection, in particular to an environmentally friendly sprinkler device for municipal engineering. Background Art

[0002] A fog cannon is a device used for air purification and dust removal. It atomizes water through a high-pressure device to produce tiny water mist particles that come into contact with pollutants in the air, thereby achieving the effect of purification and disinfection. The main uses of fog cannons include environmentally friendly dust removal and environmental cooling.

[0003] Mist cannons are often used at construction sites of municipal projects to reduce dust and cool down the construction sites. The mist cannon uses a water pump to transport water to the atomization system to form a high-pressure water flow, and then sprays the high-pressure water flow into tiny particles through a nozzle. The rotating airflow generated by the fan then sprays the water mist particles onto the target area, combining with the dust and smoke in the area to reduce the pollution concentration in the current area.

[0004] During the spraying process, due to the influence of wind in the natural environment, the spraying area of ​​the nozzle will overlap in the center, which will cause the water mist particles in the center to merge and condense into water droplets, resulting in uneven spraying. At the same time, the water mist particles outside the nozzle spraying area are less affected by the rotating airflow generated by the fan, so that the water mist particles outside are less affected, which in turn affects the spraying range of the water mist particles outside, resulting in uneven spraying.

[0005] For this purpose, the prior art has proposed a fog cannon, which changes the diameter of the frustum tube through an external cone arc, thereby pressurizing the airflow and enhancing the flow velocity of the airflow, thereby increasing the spraying range of the water mist spray particles. However, the problem of uneven spraying due to the nozzle has not been solved.

[0006] In view of this, we propose an environmentally friendly sprinkler device for municipal engineering. Summary of the invention

[0014] Preferably, the fan blade is a spiral structure; the thickness of the edge of the fan blade is less than the thickness of the center of the blade. The spiral structure enhances the degree of disturbance of the airflow by the fan blade, thereby enhancing the wind force generated by the fan blade and ensuring the strength of the wind force around the nozzle.
