PROBLEM TO BE SOLVED: To provide a high performance spray nozzle device having a high spray effect. SOLUTION: Compressed air is supplied from a compressed air source 40 to each of nozzle parts 21 and 22. Simultaneously, liquid is supplied from a liquid supply source 30 to each of the nozzle part 21 and 22. The liquid is discharged from the liquid ejection port 27b of each nozzle part 21, 22, and the liquid is crushed by a high speed vortex flow from a gas ejection port 21b to form the mist of fine liquid particles. The first and second nozzle parts 21 and 22 are arranged to face each other, and since respective ejection axes A1 and A2 are set at 80-90 degrees, the mist ejected from the first nozzle part 21 collides effectively with the mist ejected from the second nozzle part 22. The fine liquid particles in the mist is atomized further so that an ultra-fine particle mist M containing ultra-fine liquid particles can be formed simply. |
