Method for spraying a medium and spraying nozzle

A method for spraying a medium mist, in which method at least two sprays of medium mist are formed, of which a first spray (S1) is within a second medium mist spray (S2) at least at or near the spraying point, in which method during the formation of the sprays (S1, S2), the medium is set into a swirling motion at least before the discharge opening (5, 13) of the nozzle used to form each spray (S1, S2) and/or at least before the sprays (S1, S2) are mixed with each other, and that the swirling directions of different sprays (S1, S2) and/or of the medium used to produce them are opposite to each other, whereby a preferably homogeneous mist spray spread over a large area is achieved, wherein the first spray (S1) is delivered via the discharge opening (5) of a first nozzle chamber and the second spray (S2) via the discharge opening (13) of a second nozzle chamber, which latter discharge opening (13) has a ring-like shape and surrounds the first nozzle opening (5),

• said method further comprising the formation of at least one third spray (S3), within which the first spray (S1) and the second spray (S2) remain at least at or near the spraying point, so that the swirling directions of the medium of each adjacent spray (S1, S2 and S2, S3) are opposite to each other at least before the discharge opening (5, 13, 16) of the nozzle used to form each spray and/or at least before the adjacent sprays (S1, S2 and S2, S3) are mixed with each other.
