Abstract

Abstract

The spray removal mechanism of submicron aerosol particles exhibits significantly lower removal efficiency. Investigating the influence of spray characteristics on the minimum attenuation particle size of submicron aerosols is of paramount importance for severe accident management. This study, based on a self-constructed experimental platform for spray removal of aerosols, conducted experimental research on various dispersed submicron aerosol particles, and elucidated the relationship between spray characteristics and the minimum attenuation particle size of aerosols. The research findings indicate that the minimum attenuation particle size for submicron aerosol spray removal is concentrated in the particle size range of 0.3~0.5 μm. As the spray flow rate increases, the droplet size decreases, and consequently, the minimum attenuation particle size also decreases. For multi-component aerosol particles under the same spray characteristics, the minimum attenuation particle size varies and is related to the median particle size. Therefore, this study can be utilized to predict the minimum attenuation particle size of multi-component submicron aerosols under different spray characteristics, thus providing reliable data support for the management of severe accidents.
