Horizontal Electrostatic Precipitator Working Mechanism
Particle Charging: In particle charging process Dust laden gas enters the ESP horizontally and passes through discharge electrodes where particles are electrically charged.
Particle Collection: Here in this process those charged particles migrate toward the collecting plates due to electrostatic attraction.
Dust Removal: The collected dust is periodically removed by the rapper mechanism, dropping into hoppers.
Clean Gas Discharge: Clean air exits the system through an outlet duct, meeting stringent emission norms.
