Patent ID: 7901489

Claim:
An electrostatic precipitator with high efficiency comprises a casing, an inlet chamber and an outlet chamber being mounted respectively at both ends of the casing, a dust hopper being arranged at the lower part of the casing, wherein the corona discharge electrode lines and the dust-collecting electrode plates, which form a plurality of sedimentation passages, are arranged in the casing in parallel and alternately, vibration apparatuses for cleaning dust being placed respectively on the corona discharge electrode lines and the dust-collecting electrode plates, wherein the corona discharge electrode lines are connected to the negative terminal of high voltage DC output, while the dust-collecting electrode plates are connected to the positive terminal of high voltage DC output and to earth, wherein the plurality of sedimentation passages arranged in parallel and alternately in the casing are built by the corona discharge electrode lines and the dust-collecting electrode plates with a plurality of air vents, wind shields are arranged alternately at both ends of each two adjacent sedimentation passages to form a plurality of air intake sedimentation passages and air exhaust sedimentation passages which are arranged alternately, and the passages, where the wind shields are located on the side of an air outlet, are the air intake sedimentation passages, and the air exhaust sedimentation passages with the wind shields located on the side of an air inlet.
