System for scrubbing or filtering a gas stream

A system for scrubbing and/or filtering a gas stream by a pressurized working fluid, the system comprising:

• at least one working chamber having at least one inlet and at least one outlet for the gas stream, and at least one first opening providing an inflow of the working fluid;
• at least one first feed line of the working fluid, which includes at least one spray nozzle to spray the working fluid within said at least one working chamber;
• and
• a mounting system of said at least one nozzle onto said at least one working chamber at said at least one first opening,
• wherein said mounting system is configured to enable said at least one nozzle to spray the working fluid within said at least one working chamber, the working fluid passing through said at least one first opening, said mounting system being further configured to provide access to said at least one nozzle from outside with respect to said at least one working chamber, so as to enable an operator to easily performing maintenance, replacement, or adjustment operations thereon,
• wherein said mounting system is at least partially arranged externally to said working chamber, said mounting system being further configured so that said at least one nozzle is placed externally to said working chamber at the at least one first opening so that a flow of the gas stream does not invest said at least one nozzle;
• wherein said mounting system comprises a support structure with at least one seat defining an axis for said at least one nozzle, said at least one nozzle being removably inserted in the at least one seat to spray the working fluid into said working chamber, and
• wherein said support structure comprises at least one tubular element that defines said axis and that internally includes said at least one seat, said at least one tubular element further including at least one second pass-through opening transverse with respect to said axis, said at least one nozzle being slidable in said at least one tubular element between a working position, wherein said at least one nozzle, sprays the working fluid within said at least one working chamber, and a checking position, wherein said at least one nozzle is at said at least one second opening to enable the operator to check a correct operation of said at least one nozzle.
