ELECTROSTATIC PRECIPITATOR

摘要

This electrostatic precipitator is provided with a charging part, a dust collection part, and a fan. All of the positive charging part electrode plates and the negative charging part electrode plates are formed from spine-shaped spine-like discharge parts and electrode surface parts, and the spine-like discharge parts of the positive charging part electrode plates are provided upstream of the spine-like discharge parts of the negative charging part electrode plates in the airflow. In the charging part, the spine-like discharge parts and the electrode surface parts are disposed so as to be offset from each other. The spine-like discharge parts of the positive charging part electrode plates generate a positive corona toward the electrode surface parts of the negative charging part electrode plates, which have a lower potential relative to those same spine-like discharge parts, and the spine-like discharge parts of the negative charging electrode plates generate a negative corona toward the electrode surface parts of the positive charging part electrode plates, which have a higher potential relative to those same spine-like discharge parts. Dust that passes the charging parts is charged with positive and negative polarization, and the dust is collected on the entire surfaces of the charged electrode plates and grounding electrode plates in the dust collection part.
