<p>Water atomizing nozzle adapted to be used in the type of snow making machines, in which water is disintegrated into very small water particles in a ring of atomizing nozzles surrounding an air channel through which air flows at high speed, and whereby the water droplets which are carried by the air freeze to snow or ice crystals and are allowed to fall to the ground some distance from the snow making machine. The atomizing nozzle comprises an outer hollow nozzle cone (1) having an inner cone (3) mounted therein, which inner cone (3) with a front tip thereof is in bottom contact with the end of the outer cone (1), and in which there is formed a channel (4) for feeder water between the inner and outer cones (1, 3), and in which the inner cone (3) is formed with a central air channel (7) through which air of high pressure and high speed is moved straight through the inner nozzle cone (3) and out through an outlet spray bore (2) of the outer nozzle cone (1), and in which swirl chamber (5) for feeder water is provided between the outer and inner cones (1, 3) and from which swirl chamber (5) a minor amount of water can be torn off and be carried out of the nozzle together with the flow of air, thereby forming a central plume (9) of airborne nuclei, whereas the remaining part of the swirling feeder water is pressed out through the nozzle in the form of an outer hollow cone (8) of cooled or freezed water droplets surrounding the plume (9) of nuclei.</p> |
