Described is a device (1) for discharging a jet of fluid comprising a tubular body (2) extending between its own air inlet (3) and its own air outlet (4). Moreover, the device comprises blowing means (5) for generating a flow of air from the inlet opening (3) to the outlet opening (4). In addition, the device comprises a first group of nozzles (10) and a second group of nozzles (11) operatively associated with the tubular body (2) for spraying, respectively, a first fluid and a second fluid towards the flow of air. The device comprises a first conduit (16) for conveying a first fluid and a second conduit (19) for conveying a second fluid separated from the first conduit (16). According to this invention, each first fluid comprises an odour reducing solution (24) or a dust reducing solution (25) or a flame mitigating solution (26) and the second fluid is different from the first fluid. Lastly, the device (1) comprises valve means (21) interposed along each conduit in order to select the discharging of the first fluid from the first group of nozzles (10) or the second fluid from the second group of nozzles (11). |
