rightMORE INFORMATION

  • - No water using and wastewater due to dry system
    - Built in the fire sensing and extinguishing system inside of ESP main body
    - Automatic operation of fire extinguishing system when reached setting temperature
    - Auto-electric fire damper, quenching a fire with water or Co2, fire alarm
    - Spatial separation of high voltage power supply and ESP main body
    - Automatic operation of fire extinguishing system when reached setting temperature
    - Easy maintenance and repair without stop of all system by individual installation of high voltage power supply device

  • Standard of calculation in Daegu area, S. Korea:
    - Working priod : 24 hr/day, 261 day/year
    - Amount of wastewater :
    + Wet-scrubber + Adsorption Tower : 15 ton/day per 300 ㎥/min
    + Wet Electrostatic precipitator : 2ton/day per 300 ㎥/min
    - Wastewater treatment cost at Daegu Dyeing Industrial Center : 1 USD/ton
    - Amount of water usage :
    + Wet-scrubber + Adsorption Tower : 37.5 ton/day x 261 day/year = 9,787.5 ton/day per 300 ㎥/min
    + Wet Electrostatic precipitator : 5 ton/day x 261 day/year = 1,305 ton/day per 300 ㎥/min
    - Water cost : yearly amount of water usage, ton/year x 0.2 USD/ton = USD/year
    - Periodic replacement of adsorbent : 2 times/year
    - Electrical bills : 0.06 USD/kwh x 24 hr/day x 261 day/year = 376 USD/kw year
    - Contrast between Dry ESP and others system : Others system ÷ Dry ESP
