Title:
ELECTRIC DUST COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2022/038894
Kind Code:
A1
Abstract:
Provided is a technology capable of collecting particulate matter more efficiently. An electric dust collector 200 according to an embodiment of the present disclosure comprises: a charging part 210 which includes charging electrodes 212, 214 facing each other and in which a voltage is applied between the charging electrodes 212, 214 and a corona discharge is generated so that particulate matter contained in exhaust gas of main engine 100 passing through the charging part 210 is charged; and a collecting part 220 which includes collecting electrodes 222, 224 and in which a voltage is applied between the collecting electrodes 222, 224 and the particulate matter charged by the charging part 210 is collected by Coulomb force. The collecting electrode 224 that is one of the collecting electrodes 222, 224 and attracts particulate matter by Coulomb force includes a main body 224A configured to surround a hollow space, and has through hole 224B which opens to the hollow space in a flat plate part 224A1 facing the other collecting electrode.
