Electro-spray Apparatus and Dust-particle Reduction Apparatus

摘要

Fine dust reduction apparatus according to an embodiment of the present invention, a liquid distribution unit for dispensing a liquid for spraying a charged micro-droplet (micro-droplet); And a nozzle assembly that receives and charges liquid from the liquid distribution unit to spray micro-droplets. The nozzle assembly may include an insulating plate in contact with the liquid contained in the liquid distribution unit; A plurality of through holes penetrating the insulating plate; A bias electrode in electrical contact with the liquid; And a control electrode that is exposed to the atmosphere and is spaced apart from the through hole on one surface of the insulating plate to control the spray path of the microdroplets.
