DEVICE FOR CONTROLLING THE CHARGE OF AN AEROSOL POST-DISCHARGE

摘要

The invention concerns a device for controlling the charge of an aerosol comprising: - an aerosol inlet area; - a discharge area having dielectric barriers, in which charged species are generated, the discharge area and the aerosol inlet area being arranged relative to one another in such a way that the aerosol introduced in this way does not flow via the discharge area; -a mixing area for mixing the aerosol with a portion of the charged species from the discharge area; -a post-discharge area linked to the discharge area, the aerosol inlet area and the mixing area being arranged in such a way that at least a portion of a stream flowing in the post-discharge area drives at least a portion of the charged species formed in the discharge area and expelled from the discharge area by electrostatic repulsion towards said mixing area.
