The plasma-based charged aerosol generation device comprises a power supply module, an aerosol generation module and a charged aerosol generation module; the power supply module is used for providing voltage for the charged aerosol generation module to generate plasma; the aerosol generation module is used for generating uncharged aerosol in target size; the charged aerosol generation module is used for mixing the plasma, generated under the action of an electrode, and the uncharged aerosol to form charged aerosol; the charged aerosol generation module comprises an electrode device and a reaction chamber; the electrode device is used for generating the plasma under the action of the power supply module; and the reaction chamber is used for mixing the uncharged aerosol and the plasma fully to generate the charged aerosol. According to the plasma-based charged aerosol generationdevice, by additionally improving electric field force to improve a coagulation rate, the settling efficiency of to-be-cleared aerosol is further improved.

Description

technical field [0001] The invention belongs to the field of plasma, and more specifically relates to a plasma-based charged aerosol generating device. Background technique [0002] Aerosol refers to a colloidal dispersion system formed by dispersing and suspending small solid or liquid particles in a gas medium, with a diameter of 0.001 microns to 100 microns, and PM 2.5 belongs to aerosols. Most of the aerosols are solid particles or gas particles. Because of their small particle size, they can float in the air, so there are many hazards. Excessive aerosol concentration will reduce the visibility of the atmosphere and affect the driver's sight. More seriously, long-term low visibility will reduce the sunlight reaching the ground, which will reduce the surface temperature and affect the growth of vegetation. At the same time, aerosols are also extremely harmful to human health. Generally speaking, particles with a diameter greater than 12 microns cannot enter the human bod...
