[0002] A dust suppression device refers to a device used to reduce the dust content in the air environment, in which open spaces generally use the method of spraying water mist to suppress dust.

[0003] In the current existing technology, in order to protect the air environment during the construction process, people will install an atomizing dust reduction device on the construction site. The atomizing dust reduction device is mainly composed of multiple atomizing nozzles, connecting pipes and hoses. The connecting pipes are vertically supported and fixed on the construction site through some supporting rods. The hose is connected to a water pump, and the water pump is used to pump clean water into the atomizing nozzle to spray water mist, thereby relying on the water mist to play a role in dust reduction.

[0004] However, when in use, a plurality of atomizing nozzles are installed on the top of the dust reduction device, but these atomizing nozzles are fixed differently, resulting in a fixed spraying area, dead angles, and a small spraying range, which in turn affects the dust reduction effect; therefore, an air environment dust reduction device is proposed to address the above problems.
