The invention relates to mining and can be used to control dust during various industrial processes in mines and mines.

A nozzle for irrigation of foci of dust formation is known, including a casing, a nozzle with a perforated partition, a central nozzle for supplying air and a side nozzle for supplying a liquid (D).

The disadvantage of this nozzle is the low efficiency of dust suppression.

Closest to the invention is a dust suppression device comprising a cylindrical body, a shaft, a brush, a foam dispenser and a nozzle for supplying a frother 21.

The disadvantage of the known devices

the efficiency of the suppression of fine dust is low.

The purpose of the invention is to improve the effectiveness of the suppression of fine dust by electroplating foam.

The goal is achieved by the fact that the device for dust suppression, comprising a cylindrical body, a shaft, a brush, a foam diffuser and a nozzle for supplying a frother, is equipped with an impeller rotatably mounted on the shaft, a source of compressed air and a frother for feeding the frother. a cone-shaped outlet part, on which a foam ripper is installed, made in the form of a nozzle, which is a part of a sphere made of an electrically conductive material layer, covered on both sides with dielectric layers, with through holes on the surface of the nozzle, dielectric tubes with protruding ends from the outer surface are installed, while the brush is fixed on the impeller, the profile of which is made in accordance with the inner surface of the cap.

The drawing shows a diagram of the device for dust suppression, section.

A device for suppressing fine dust contains a cylindrical cone-expanding body 1, a source of compressed air 2, a nozzle 3, a shaft 4 on which an impeller 5 rotatably mounted with a brush b, and a nozzle 7 mounted on a cone-expanding part the cylindrical body 1, is made as a part of a sphere made of electrically conductive material 8 (for example, metal), covered on both sides with a dielectric layer 9. For a uniform coating of the nozzle with a foaming solution, a wing profile ca. 5 configured in accordance with the inner wall of the nozzle 7. On the metal layer 8, the nozzle 7 is fed a certain electric potential polarity. Through the entire surface of the nozzle 7 there are through holes with a diameter of 1-1.5 m in which dielectric tubes 10 are located, projecting at one end, on the outside of the nozzle 7.

The paGoTaeTj device is as follows.

Nozzle 3 sprays foaming solution. Under the action of compressed air, the impeller 5 with the brush 6 mounted on the shaft 4 is rotated. In this case, the brush, wetted by the foaming solution, evenly covers the inner wall of the nozzle 7 with a thin film of liquid. The liquid, which penetrates the dielectric tubes 10 in contact with the metal layer 8 of the nozzle 7, receives some electrical potential. Under the action of compressed air at the outlet of the dielectric tubes 10, monodisperse electrically charged foam bubbles are formed, which, falling into the dusty space, trap the smallest particles of soaring dust.

Experimental verification has proven that its use allows for an increase in the effectiveness of the suppression of fine dust by 30-35%.
