摘要： A gas stream scrubbing and/or filtration system using a pressurized working fluid includes a working chamber having an inlet and an outlet for the gas stream, and a first opening for entering the working fluid; a first feeding line of the working fluid having a spraying nozzle for spraying the working fluid inside the working chamber; and a mounting system of the nozzle on the working chamber at the first opening. In particular, the mounting system is configured to enable the nozzle to spray the working fluid inside the working chamber, passing through the first opening. The mounting system is further configured to provide access to the nozzle from outside of the working chamber, so as to allow an operator to easily perform maintenance, replacement and/or adjustments thereof.

摘要： A system for the treatment of exhaust gases flowing in and/or flowing out from a tunnel (T) overlying a roadway (R) through a ventilation duct (TV). The system comprises: filtering means (20) to filter the exhaust gases passing through the ventilation duct (TV); fan means (V) to force the evacuation of exhaust gases from the tunnel (T) towards the outer environment or the inflow of the exhaust gases from the outer environment into the tunnel (T) through the ventilation duct (TV); detecting means (10) of at least one parameter of the exhaust gases; control means (30) to activate the filtering means (20) in response to the detection by the first (10) of the exceeding of a predetermined threshold value of the at least one parameter. The filtering means (20) comprise at least one filtering unit (20′, 20″, 20′″) that includes: at least one water reservoir (21); pumping means which include at least one high pressure pump (22); a plurality of high pressure nozzles (24) to spray atomized water into drops having an average diameter lower than 500 μm, preferably lower than 250 μm, and at a minimum working pressure of 150 bar, preferably at a minimum working pressure of 200 bar; a line of fluid connection (25) of said at least one water reservoir (21) with said high pressure nozzles (24) passing through said pumping means (22).

摘要： An apparatus for the spraying of an area of interest (S) of a high-pressure working fluid (V) wherein the apparatus is susceptible to move relatively to the ground (S) along a direction of reciprocal advancement (d) and it comprises at least one tank (2) for the working fluid (V), at least one outlet nozzle (41) and a fluid connecting line (4) extending from the tank (2) towards the outlet nozzle (41). The apparatus further comprises supply means (5) of the working fluid (V) that include a high-pressure pump and at least one spraying device (10) placed along the fluid connecting line (4) the former (5) upstream with respect to the latter (10). Furthermore, the spraying device (10) comprises a support structure (11) that comprises a first plate (12), motor means (35) acting upon the first plate (12) to promote the eccentric rotation thereof around a first axis (Z) and at least one manifold (42) placed on the first plate (12) to move integrally therewith. In particular, the latter (42) comprises at least one outlet nozzle (41) oriented so as to spray a jet of working fluid (V) towards the ground (S). The first plate (12) is mounted movable with said support structure (11) so that upon the movement along the direction of reciprocal advancement (d) of the apparatus (1) and of the ground (S), the jet flowing from the outlet nozzle (41) hits the latter with helical path.
