The dry mist humidification system mixes the two fluids of gas and water, andthen undergoes three times of gasification and shearing, and is atomizedagain by the supersonic air ejected from the nozzle. At the same time ofrepeated shortening, the ultrasonic droplets of 33000-40000 Hz are moremicronized, and the principle of the equalization atomization system realizesmulti-stage atomization to obtain a good spray effect. The diameter of thespray particles is 5-7 microns.
