PURPOSE: To spray water over a wide range with a small amt. of air by connecting a branch in the upper direction of a liquid header pipe, and disposing an externally mixing type gas ejecting part for forming a liquid-gas mixture in the outlet part thereof.
CONSTITUTION: The top end of a water branch 4 disposed in the upper part of a water header 2 is extended to the outside of an air header 3 and air is discharged from the header 3 to the outside from an air branch 5. The number of the branches 5 is 2 per one water branch in this case but is permitted to use ≥3 depending upon the condition of use. Then the flow of the water and the flow of the air from the two directions collide roughly simultaneously against each other in the front end part 6 of the branch 4 and the branch 5, and the water is atomized by the energy of the air; at the same time, the water drops atomized by the colliding film of the air formed by the two streams of the air flow spread. A prescribed spraying angle is obtainable by selecting adequately the angle 9 at which the flow of the water and the flow of the air collide against each other between 0W60°.
