Abstract
In an atomizer device for the production of a liquid-gas mixture (4), the mixture (4) is introduced, particularly for compression, into a nozzle arrangement (3) in which the kinetic energy of the mixture (4) is in large part converted into compression energy by a pressure rise of the air. The atomizer device (2) includes a central air feed (16) and a nozzle chamber (18) for the supply of liquid surrounding the air feed. At or in the atomizing device, means (17) are arranged in the nozzle chamber for producing a swirled liquid flow in the nozzle chamber (18), and the swirled liquid flow emerges via a nozzle aperture (19) surrounding the air feed.
Claims4
An atomizer device for the production of a liquid-gas mixture, the mixture useful for being introduced for the purpose of compression into a nozzle arrangement in which the kinetic energy of the mixture is in large part converted into compression energy of the gaseous component, the atomizer device comprising:
- a nozzle member having an at least substantially central pipe for the gaseous medium, a rotationally symmetrical nozzle chamber surrounding the pipe for the liquid medium, and a nozzle aperture;
- a liquid feed having means for producing a swirled liquid flow in the nozzle chamber;
- wherein the nozzle aperture coaxially encloses the pipe;
- and
- wherein the liquid feed opens tangentially into the nozzle chamber.
A method for the production of a liquid-gas mixture by an atomizer device, the mixture produced useful for being introduced into a nozzle arrangement in which the kinetic energy of the mixture is in large part converted into compression energy of the gaseous component, the method comprising:
- causing a swirled liquid flow to emerge from a nozzle aperture of the atomizer device to produce a swirling hollow conical spray expanding in a flow direction, and to produce a reduced pressure zone within the spray;
- and
- causing the gaseous medium to enter the reduced pressure zone via a central feed;
- and
- introducing the swirled liquid flow in the nozzle chamber through at least one liquid feed opening tangentially into the nozzle chamber.
