Description of the Related Art A humidifier using a water injection system has the advantage of requiring a low power without a steam generator, but has a disadvantage that the diffusion range of spray is narrow and it is difficult to mix with air. Conventionally, as means for spraying the spray in a flat manner, as a sprayer for an industrial process, for example, as shown in Japanese Utility Model Laid-Open No. 4-134452, an air nozzle for flat blowing is provided on both sides of the spray ejected from the nozzle. It is known that the spray is spread flat by air ejected from an air nozzle. However, in this conventional device, the diffusion width and the reach of the spray are not so large, and the capacity for humidification in a large-scale facility is insufficient.

も少ないという不都合がある。There is also known a method in which a spray nozzle is provided in a direction opposite to the air flow of the air to be humidified, and the air flow collides with the spray to make the water droplets of the mist fine while causing the spray to flow backward. However, since the amount of momentum of the water droplets of the mist is small, there is an inconvenience that the degree of miniaturization is small and the range of diffusion in the air current is small.

する。According to a first aspect of the present invention, a swirling humidifying airflow is generated by a spray ejected from a spray nozzle and a spiral airflow swirling around the spray. Then, the humidification target airflow is blown at an inclination angle of 30 to 90 ° to the whole of the swirling humidification air flow in opposition to the swirling humidification airflow, and the swirling humidification airflow is diverted and diffused. According to this means, the spray ejected from the spray nozzle advances as a humidified airflow mixed with the air exiting from the air nozzle of the air discharge pipe while spiraling, but the humidified object sprayed obliquely from the front or from the side By the air flow, the traveling direction is changed and the amount of air mixed is increased while the water droplets of the mist are subdivided, and the air is diffused widely.
