Technical Field

[0001] The utility model belongs to the technical field of dust removal devices, and in particular relates to an intelligent dust suppression device for a coal yard. Background Art

[0002] Dry fog dust suppression technology captures dust through cloud-like water mist, allowing the water mist to combine with dust particles in the air to form agglomerates of dust and water mist, which settle under the action of gravity, thus achieving dust suppression at the source. It can effectively solve the problem of dealing with unorganized dust emissions in locally closed or semi-closed states.

[0003] Chinese patent application No. 202220916143.7 discloses an intelligent dry fog dust suppression device for mines, including a supporting back plate, a supporting top seat and a supporting base, wherein the supporting top seat is installed at the upper end of the right side of the supporting back plate, and the supporting base is installed at the lower end of the right side of the supporting back plate, and also includes: a spray mechanism, wherein the spray mechanism is installed between the supporting top seat and the supporting base; the spray mechanism includes a connecting mechanism, wherein the connecting mechanism is installed on the supporting back plate, the spray mechanism includes a hydraulic cylinder and a supporting seat, and the hydraulic cylinder is installed at the upper end of the supporting base. The beneficial effect of the utility model is as follows: by arranging an air nozzle between the spray nozzles in the dry fog dust suppression device, after the mist is sprayed out, the direction and speed of the mist blowing out are changed by blowing, and by arranging a shutter on the outside of the spray nozzle, the spraying angle of the mist is adjusted to accelerate the efficiency of the mist in adsorbing dust.
