A centrifugal fan 7 is installed on the top of the water storage tank 1, and the air inlet of the centrifugal fan 7 extends into the water storage tank 1. The air outlet of the centrifugal fan 7 is connected to a right-angle elbow 8, and the other end of the right-angle elbow 8 is installed with a hollow rotating platform 9. A spray pipe 10 is installed on the turntable of the hollow rotating platform 9, and one end of the spray pipe 10 extends from the cavity core of the hollow rotating platform 9 into the right-angle elbow 8. Ultrasonic vibration is used to make the liquid generate tiny droplets, thereby forming atomization. Under the pumping of the centrifugal fan 7, dust is reduced by spraying from the spray pipe 10.

It does not require people to frequently operate to change the spraying direction, and the whole process is PLC automated control. On the one hand, it saves people's operation time, and on the other hand, it also improves the dust reduction efficiency and can be applicable to more construction sites. The ultrasonic atomizer 5, the liquid level probe 6, the centrifugal fan 7 and the hollow rotating platform 9 are all electrically connected to the PLC controller 3.

[0019] Specifically, an air inlet hole 11 is opened on the side wall of the water storage tank 1, and the air inlet hole 11 is located in the upper part of the water storage tank 1.

[0020] In this embodiment, the centrifugal fan 7 is mainly composed of an impeller, a casing, a shaft and a motor. The impeller is the main working part that generates wind pressure and transmits energy. The casing is mainly used to introduce and discharge gas, and at the same time convert part of the kinetic energy of the gas into pressure energy. The shaft installs and fixes the impeller and is connected to the motor through a coupling. The air inlet hole 11 is used to keep the centrifugal fan 7 continuously pumping water mist.
