1. A method of dedusting of gas medium passing through a principally horizontal cylindrical duct, particularly of air in mining conditions, by means of spraying with liquid from central axis of this duct towards the side limiting this duct, characterised in that the passing gas medium is sprayed within at least one layer located helically in relation to the central axis of the duct.6. A device for dedusting by means of spraying with liquid of gas medium passing through a duct principally horizontal, which has along the central axis of its principally cylindrical casing a centrifugal sprayer in form of a tubular element, characterised in that the tubular element (1) has in its side on the outside a conical cavity (4) located transversely in relation to the tubular element (1) axis and spaced along at least one helically located line (3), and in side surface of each cavity (4) is a pair of outlet openings (5) connecting duct space of the tubular element (1) with outer space, such that their axes form with the side surface of cavity (4) the same angle.<IMAGE>
