The present invention proposes an anode plate with a dust collection hood, comprising an anode plate, wherein the anode plate is composed of a 480C plate and a metal filter plate welded on one side thereof, wherein the metal filter plate comprises a steel plate arranged in the middle position along its length direction and a first half metal mesh and a second half metal mesh welded on both sides of the steel plate, wherein the 480C plate and the steel plate are welded and fixed by a plurality of steel pipes arranged at intervals along the length direction of the steel plate. Compared with conventional anode plates, it is more efficient in capturing fine particles escaping along the side of the anode plate, and solves the problem of dust concentration limiting the outlet of the electrostatic precipitator and the problem of low collection efficiency of ultrafine particles and particles that are difficult to charge, so the dust removal efficiency is increased, and the minimum outlet dust concentration breaks through the existing bottleneck, and can stably achieve 10mg / m 3 Even 5 mg / m 3 The dust concentration at the outlet of the electrostatic precipitator is as follows.
