Separation performance of a new spray-type singlet oxygen generator (SOG), named strongly swirling flow singlet oxygen generator (SSF-SOG), is studied by computational fluid dynamics (CFD) analysis and experiments. The flow field and the separation performance of the SSF-SOG are analyzed using Fluent® soft firstly, and the results show that the separation performance of SSF-SOG is effective for liquid droplets whose diameters are greater than 5μm. Then, using Phase Doppler Particle Analyzer (PDPA), the diameters of liquid droplets in reaction zone and gas outlet of SSF-SOG are measured. The results show that in the reaction zone the diameters of the liquid droplets mainly concentrated on 10μm, and only a little of droplets of which the diameter are under 5μm are detected in the gas outlet of SSF-SOG, which are well consistent with the results of the CFD analysis on SSF-SOG.
