Electrostatic precipitator with high efficiency

Abstract

This invention relates to an electrostatic precipitator suitable for removing industrial dust particles. This electrostatic precipitator with high efficiency includes a casing, in which the corona discharge electrode lines and the dust-collecting electrode plates, which form a plurality of sedimentation passages, are arranged in parallel and alternately. The vibration apparatuses for cleaning dust are placed respectively on the corona discharge electrode lines and the dust-collecting electrode plates. The 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. The passages, where the wind shields are located on the side of air outlet are the air intake sedimentation passages and the air exhaust sedimentation passages with the wind shields located on the side of air inlet. There is a plurality of air vents distributed on the dust-collecting electrode plates. A valve is mounted on the side of air outlet of each air exhaust sedimentation passage for closing the air outlet.
