Tunnel Electrostatic Precipitator

Tunnel Electrostatic Precipitator is an effective means of securing the field of view in long tunnels that penetrate mountainous areas or tunnels with heavy traffic. Our type of Tunnel Electrostatic Precipitator exhibits stable performance by selecting materials and shapes that are excellent in weather resistance even in cold climates.

Functions and Features

  • High reliability : The flat strip type discharge electrodes with spikes are supported by extensive experience in industrial electrostatic precipitators.
  • High Dust Collection Performance : Achieves uniform discharge with optimal electrode configuration and high dust collection performance.
  • Long-term performance stability : Since the flat strip type discharge electrodes with spikes are used at the corona discharge section, there is no trouble due to the electrode breakage.

Electrodes structure of dust collecting unit

  • Discharge electrodes (flat strip type with spikes) and Collecting electrodes are arranged alternately.
  • Since discharge electrodes (flat strip type with spikes) are used, the starting point of discharge is clear, resulting in uniform discharge and high dust collecting performance.

Water washing facility

  • Dust collected on the electrodes is periodically cleaned and removed with pressurized water to clean the electrode plates.
  • Wastewater is treated and discharged as necessary in accordance with the site's drainage standards.
