To provide an electric dust collector which collects particulate matters in exhaust gas occurring due to combustion of a diesel engine, enables reduction of adhesion of the particulate matters in the exhaust gas to surfaces of insulators, and maintains insulation quality of the insulators.SOLUTION: One embodiment of the invention relates to an electric dust collector which collects particulate matters in exhaust gas occurring due to combustion of a diesel engine and includes: a cylindrical housing having an inlet into which the exhaust gas flows, and an outlet from which the exhaust gas flows and in which high voltage electrodes are disposed; multiple air purge parts which are provided on a side surface of the housing at intervals in an axial direction of the housing and supply a gas to the interior of the housing; and multiple insulators respectively provided at the air purge parts and support the high voltage electrodes. A flow rate of the gas supplied to each of the air purge parts is set according to a pressure of the exhaust gas in a position of each of the air purge parts.SELECTED DRAWING: Figure 2 【課題】ディーゼルエンジンの燃焼による排ガス中の粒子状物質を捕集する電気集塵装置であって、碍子の表面に排ガス中の粒子状物質が付着することを低減し、碍子の絶縁性を維持する電気集塵装置を提供すること。【解決手段】本発明の一態様は、ディーゼルエンジンの燃焼による排ガス中の粒子状物質を捕集する電気集塵装置であって、前記排ガスが流入する入口と前記排ガスが流出する出口とを有し、高電圧電極が配置された筒型の筐体と、前記筐体の側面に前記筐体の軸方向に間隔を空けて設けられ、気体を前記筐体の内部に供給する複数のエアパージ部と、前記複数のエアパージ部のそれぞれに設けられ、前記高電圧電極を支持する複数の碍子と、を備え、前記複数のエアパージ部のそれぞれに供給される前記気体の流量は、前記複数のエアパージ部のそれぞれの位置における前記排ガスの圧力に応じた流量となる。【選択図】図２
