Abstract
The invention relates to a mist generating head (34) comprising an injection unit (70) of the type used in diesel engines. Said head atomizes the liquid to be nebulized at a high frequency. The stream of liquid droplets emitted by the injection unit (70) is surrounded and broken up further by a gas nozzle (102) which encloses the outlet opening of the injection unit and is positioned slightly downstream of same.
Claims17
A mist generating head for generating a mist of liquid droplets distributed in a gas flow for producing a liquid film or a layer of adjacent liquid droplets on the surface of a workpiece, having a housing (66, 96), in which a liquid feed channel (130) and a gas feed channel (90) are formed, and having a nebulizing device connected to the liquid feed channel (130) and the gas feed channel (90), the nebulizing device comprising a liquid nozzle (74) connected to the pressurized liquid feed channel (130);
- the liquid flow through the liquid nozzle (74) being controllable by an intermittently operable valve (76, 78), the housing (66, 96) carrying a gas nozzle (102) which is connected to the gas feed channel (90), and the directional characteristics of liquid nozzle (74) and gas nozzle (102) overlapping, wherein the valve member (78) of the valve (76, 78) operates at a frequency of about 10 to about 100 Hz.
A mist generating head as claimed in 1, wherein the pressure in the liquid feed channel (130) is between 2 and 8 bar.
A mist generating head for generating a mist of liquid droplets distributed in a gas flow for producing a liquid film or a layer of adjacent liquid droplets on the surface of a workpiece, having a housing (66, 96), in which a liquid feed channel (130) and a gas feed channel (90) are formed, and having a nebulizing device connected to the liquid feed channel (130) and the gas feed channel (90), the nebulizing device comprising a liquid nozzle (74) connected to the pressurized liquid feed channel (130) having a pressure between 2 and 8 bar;
