Dedusting spray head

The invention discloses a dedusting spray head, comprising a nozzle cover, a nozzle holder and a nozzle core, wherein the nozzle holder is provided with an inner cavity, the inner cavity at the rear part of the nozzle holder is internally provided with the nozzle core, the nozzle cover is connected with the rear end of the nozzle holder, the chassis of the nozzle core is uniformly provided with multiple guide holes which are through front and back, a cone-shaped bump is arranged at a center position of the rear end face of the chassis of the nozzle core, the nozzle cover is internally provided with a cone-shaped concave hole, the cone-shaped bump is inserted into the cone-shaped concave hole, a gap is arranged between the cone-shaped bump and the cone-shaped concave hole, the guide holes are communicated with the gap, a spray orifice is arranged at the center position of the rear end of the nozzle cover and the spray orifice is communicated with the gap. By adopting the dedusting spray head disclosed by the invention, water is input by virtue of the nozzle holder and is sprayed onto the inclined plane of the cone-shaped concave hole in the nozzle cover, then the water is sprayed out from the gap where the nozzle cover and the nozzle core are in fit, and an atomized water curtain is formed, thus coverage area is large, coal ash and floating dust produced in an operation process can be more effectively reduced, dust falling effect is good, and the water is saved.
