The utility model relates to the technical field of
coal yard dust suppression, and discloses an improved
coal yard spraying dust suppression device which comprises a guide
pipe, the two ends of the guide
pipe are in a sealed state, a plurality of water distribution pipes are fixedly installed at the bottom of the guide
pipe, and the top ends of the water distribution pipes are all communicated with the interior of the guide pipe. And nozzles are fixedly mounted at the bottom ends of the multiple water distribution pipes correspondingly, and a water inlet is formed in the middle of the top of the guide pipe. Through the cooperation of the water-air mixer, the
water supply pipe, the one-way valve and the
air compressor, water and air can be conveniently discharged into the water-air mixer at the same time, water and air are mixed through the water-air mixer, and water can flow more rapidly by pressing air into water, so that the
water supply efficiency is improved, and the
water supply cost is reduced. And through cooperation of a connector, a
metal hose, a guide pipe, a plurality of water distribution pipes and spray heads,
water vapor can be conveniently and rapidly sprayed out through the spray heads, so that the spraying dust suppression effect is improved, and
diffusion of
coal dust is conveniently and rapidly suppressed.
