The Blue Ocean Intelligent Environmental Protection Cloud and Mist Dust Suppression System adopts the ultrasonic cloud and mist dust suppression mechanism, which uses high-pressure airflow to impact the resonant cavity in the nozzle to generate ultrasonic waves. With the help of ultrasonic waves, liquid water is fully atomized into droplets with a particle size of 1-10 microns, which are sprayed out from the nozzle head and can effectively suppress and reduce dust. The system mainly consists of an air compressor, an air storage tank, a cloud and mist host, an intelligent distribution control box, a cloud and mist box, nozzles, etc.
