An electric dust-collection unit including needle electrodes for the purpose of charging particulates within the air by causing corona discharges around their tips, collector cells (collector electrodes) arranged in tubular shape corresponding to the needle electrodes for the purpose of attracting and collecting the charged particulates by static electricity, and deflecting electrodes which are arranged in such a way as to be inserted within the collector cells for the purpose of imparting a deflecting force on the charged particles in the direction of the collector cells. The deflecting electrodes being configured in the form of a hollow column including a forward plate section having a mounting hole for the purpose of fitting and retaining the needle electrode, and side plate sections facing the collector cell at a prescribed distance. While the needle electrodes are fixed on to the forward plate sections of the deflecting electrodes in such a way that their tips protrude from the surface of the forward plate sections, while their bodies are inserted firmly in the mounting hole. |
