Year: 2026
Type: article
Abstract: In the event of an accidental fire in a glove box, submicron plutonium aerosols may be released into the plant area, which not only poses an internal exposure hazard to staff but also risks radioactive environmental pollution. Existing studies have shown that fixative droplets can effectively control aerosols and inhibit their resuspension, but there is still room for improvement in the control effect on submicron aerosols. To this end, this study adopts inductive charging technology to charge fixative droplets, and enhances the control effect by means of the Coulomb interaction between droplets and aerosols. Aerosol control experiments are carried out in a glove box system equipped with a charging device and a pneumatic atomisation device to systematically investigate the effects of voltage and electrode-related parameters on the control effect. The experimental results are explained in combination with theoretical analysis and simulation calculations. The results demonstrate that charging fixative droplets can significantly enhance the control efficiency for aerosols in the range of 0.5 μ m–1 μ m, providing important technical support for reducing the risk of internal exposure of personnel and ensuring environmental safety.
