Large-range dry fog dust suppression device and use method thereof

The invention discloses a large-range dry fog dust suppression device and a using method thereof, and belongs to the technical field of dry fog dust suppression. A sliding sleeve moves upwards, pull rods can be pulled to generate angle deflection, and the two opposite pull rods can pull a dust suppression cover to rotate around pin shafts at the ends of the pull rods; and in the dry fog dust suppression process, an exhaust fan is started, the exhaust fan can suck part of dry fog and discharge the dry fog to one side of the dust suppression cover, and the exhaust fan is matched with the nozzles to spray downwards, so that the dust suppression effect is improved, and the dust suppression efficiency is improved. Due to the fact that the dry fog sprayed out of the nozzle has a certain flowing speed, external air containing smoke dust can be attracted to enter the dust suppression cover through the exhaust holes, the purpose of multidirectional dry fog dust suppression is achieved, smoke dust is prevented from bei
