The atomization is divided into two stages: the pressure nozzle first forms a liquid film, which is atomized by the air flow for the second time to make the droplets finer.
The advantages of this type of nozzle are:
(1) By adjusting the pressure of compressed air, the diameter of the droplet can be adjusted, and the operation is simple;
(2) Large-volume, high-viscosity feed liquids can also be atomized into fine droplets; 3 If compressed air is disabled, the original pressure nozzles can also be used.
Air atomizer is mainly used in laboratories and intermediate factories, and its power consumption is large. The material liquid that cannot be atomized by the first two atomizers may be atomized by using the airflow atomizer. High-viscosity pastes, pastes and filter cake materials can be atomized using a three-fluid nozzle.
