Method for producing a spray jet, and two-component nozzle

A two-component nozzle for spraying a liquid/gas mixture, said nozzle comprising:

• a nozzle housing comprising a liquid inlet, a gas inlet, an outlet opening in communication with the liquid inlet and the gas inlet and through which outlet opening a spray jet including both liquid and gas drops exits the nozzle;
• a tube disposed within the nozzle housing and arranged concentrically with respect to a central longitudinal axis of the outlet opening, the tube having a free end and including a plurality of gas outlet openings disposed around the central longitudinal axis and opening radially outwardly with respect thereto, the plurality of gas outlet openings being disposed to communicate directly with the spray jet exiting the outlet opening such that gas from the plurality of gas outlet openings is mixed with the liquid and gas drops of the spray jet immediately upon exit of the gas from the plurality of gas outlet openings;
• a deflecting body disposed on the free end of the tube, the plurality of gas outlet openings being disposed upstream, with respect to a flow direction through the nozzle, of the deflecting body;
• and
• an exit chamber disposed downstream of the liquid inlet and gas inlet, the outlet opening being disposed at a downstream end of the exit chamber and liquid and gas drops from the exit chamber exit the nozzle through the outlet opening;
• wherein the exit chamber has a conical configuration which enlarges radially in an upstream to downstream flow direction through the nozzle.
