Novel three-stage negative pressure atomization dust falling device

The utility model discloses a novel three-stage negative pressure atomization dust falling device, and particularly relates to the field of coal safety production dust falling devices. The defects that most of existing atomization devices are low-pressure nozzles, the atomization rate is low, the atomization angle is small, water mist particles are large, and dust cannot be effectively captured are overcome. The utility model discloses a novel three-stage negative pressure atomization dust falling device. The device comprises a first-stage negative pressure atomization mechanism, a second-stage negative pressure atomization mechanism and a third-stage negative pressure atomization mechanism which are sequentially connected through air pipes. The air inlet end of the first-stage negative pressure atomization mechanism is also connected with an air pipe; each of the first-stage negative pressure atomization mechanism, the second-stage negative pressure atomization mechanism and the third-stage negative pressure
