Abstract
A system for removing fine particulate matter from an aerosol, which, using a fine particulate matter capture device () comprising sheet members () parallel to each other and an interferent () between the sheet members, causes the aerosol to form a turbulent flow in passages between the sheet members (), settles fine particulate matter in the aerosol on the outer surfaces of the sheet members under the action of turbulent fluctuation, thermophoretic force and/or vapor pressure gradient force, and meanwhile forms a water film on the outer surfaces of the sheet members () to prevent settled particulate matter from being carried away again by an air flow. The system is able to effectively remove fine particulate matter from an aerosol, especially sub-micron particulate matter, and significantly reduce the number concentration thereof.
