<p>PROBLEM TO BE SOLVED: To provide an electric dust collector where dust in an exhaust gas adhering to and depositing on a dust collecting electrode can be effectively removed without using a cleaning means and in which a reusable dust removing means is used.SOLUTION: In an electric dust collector 10, dust D is removed from an exhaust gas by that the dust D in the exhaust gas adheres to and deposits on a dust collecting electrode 12 side by electrostatic force applying a high voltage between a discharge electrode 11 and a dust collecting electrode 12. The electric dust collector 10 comprises: a beads injector 13 to peel and fall off the dust D from the dust collecting electrode 12 by the impact force of beads 20 caused by the blowing impact of a plurality of the beads 20 to the dust D adhering to and depositing on the dust collecting electrode 12; and a beads recovery device 14 where the beads 20 used for the peeling of the dust D are recovered, returned to the beads injector 13 and reused for the peeling of the dust D.</p> |
