Collecting Plate & Discharge Electrode

Collecting Plate and Discharge Electrode
Collecting Plates: Capturing the Charged Particles
  • Electrostatic Attraction:
    • The collecting plates are flat, metallic surfaces placed parallel to the discharge electrodes.
    • These plates are oppositely charged (usually positive) relative to the charged particles.
    • The charged particles are attracted to the plates and adhere to them due to electrostatic forces.
  • Particle Accumulation:
    • Over time, a layer of particulate matter accumulates on the plates.
    • Regular cleaning prevents this buildup from reducing collection efficiency.

Discharge Electrodes: Ionizing the Particles

  • Corona Discharge Generation:
    • The discharge electrodes are thin, wire-like structures connected to a high-voltage power source.
    • These electrodes produce a corona discharge, which generates a strong electric field and releases ions into the surrounding space.
  • Particle Ionization:
    • When dust-laden gas flows through the ESP, the particles are exposed to the electric field.
    • The particles interact with the ions, acquiring a negative or positive charge, depending on the electrode’s polarity.
  •  Field Uniformity:
    • The precise placement of discharge electrodes ensures the electrical field is evenly distributed, enabling consistent particle charging across the gas stream.
  • High Efficiency: Plates and electrodes are engineered for superior particle capture.
  • Durable Materials: Designed with high-alloy materials to withstand harsh operating conditions.
  • Precision Charging: Ensures minimal energy loss and maximum collection efficiency.
