Micro-particle salt mist generating device

The utility model discloses a trace particle salt mist generating device which comprises a generating box with a salt mist outlet in the top and air ejectors arranged in the generating box, the air ejectors are arranged below the artificial seawater liquid level of the generating box, a plurality of air ejectors are connected in series to form an air ejection unit, and the air ejection unit is connected with the generating box. An electromagnetic switch valve is used for controlling the on-off of the process gas of the air injection unit; and a plurality of paths of air injection units are mounted in the generation box in parallel. According to the utility model, after entering the air ejector, high-pressure process air passes through the internal airflow acceleration channel and then is ejected out from the annularly distributed multiple holes, the ejected high-speed airflow stirs and crushes the liquid level to form salt mist generation, and generated salt mist particles flow out from the outlet at the top
