Electrostatic dust collection device

The utility model discloses an electrostatic dust collection device which comprises an electrostatic dust collection cylinder, the cylinder wall of the electrostatic dust collection cylinder is an anode wall, a cathode tube is arranged on the upper portion of the center position of the electrostatic dust collection cylinder, a cathode needle is arranged on the lower portion of the center position of the electrostatic dust collection cylinder, and the top of the cathode tube and the bottom of the cathode needle are both connected with a cathode power source. A dusty gas inlet and a clean gas outlet are respectively formed in the lower part and the upper part of the electrostatic dust collection cylinder. The problem that when an existing electrostatic dust collection mechanism conducts corona discharge, the electrostatic field intensity is reduced due to the fact that a cathode wire is a through wire is solved. 本实用新型公开了一种静电除尘装置，包括静电除尘筒，所述静电除尘筒的筒壁为阳极壁，所述静电除尘筒中心位置的上部设有阴极管，所述静电除尘筒中心位置的下部则设有阴极针，所述阴极管的顶部和阴极针底部均与阴极电
