Abstract: Abstract:In order to improve efficiency of the electrostatic precipitator and to ensure flue gas dust emission to meet the standard requirement, the electrostatic precipitator was reformed. The working principle and the features of the electrostatic precipitator with movable pole plate were expounded. The reformation content of the electrostatic precipitator with movable pole plate of unit No.10 in a power plant was introduced. After the reformation, the dust emission mass concentration in outlet of the desulphurization tower is 24.66mg/m3, amended to 6% oxygen, the emission mass concentration is 23.86mg/m3, which is lower than 30mg/m3, the standard upper limit. The expectant target of the reformation was realized.
