The research of removing sodium aerosol

This paper represents A method to remove sodium combustion aerosol of CEFR is represented. A aqueous scrubber and a filter is used in this method. An experiment facility was built up. When the entrance concentration of sodium aerosol is up to 7 mg/L, the efficiency of scrubber is up to 85 %, and the total efficiency is 96%±2%; When the entrance concentration of sodium aero- sol is up to 1 mg/L and below 7 mg/L, the efficiency of scrubber is up to 74%, and the total efficiency is 87%± %; when the entrance concentration of sodi- um aerosol is below 1 mg/L, the efficiency of scrubber is about 40%, and the total efficiency is about 50%. After cleaning, the ventilation exit concentration of sodium aerosol is below to 0.5 mg/L. The act of sodium aerosol is also researched. (authors)
