Abstract: Disclosed are an aperture-adjustable mixed-flow nozzle and its atomization method. The nozzle includes a cylindrical shell with an airflow chamber and a mixed-flow chamber. The airflow chamber is connected to an air inlet, and the mixed-flow chamber is connected to a liquid inlet. An nozzle is provided at the bottom wall of the mixed-flow chamber on the cylindrical shell. The cylindrical shell allows airflow from the airflow chamber to enter the mixed-flow chamber through an adjusting shaft. A swirling flow path is disposed around the outer periphery of the adjusting shaft, and a gas path for connecting the airflow chamber and the mixed-flow chamber is disposed inside the adjusting shaft. By adjusting the nozzle aperture size, not only is the problem of nozzle blockage resolved, but it also allows for control of atomization effects and spray field conditions, making it more effective for complex dust-producing environments on-site.
