Electrostatic Collection of Micro an Nanoparticles with EDC at the Point-of-Use

Electrostatic Fine Dust Collection with EDC
Electrostatic Collection of micro and nanoparticles with EDC

The Waste Gas Treatment Product and Service Portfolio of DAS includes EDC, an electrostatic dust collector responsible for the treatment of micro and nanoparticle-containing or aerosol-containing process waste gases up to 90 m³/h as they accrue, for example, in solar cell manufacturing. The dust collector reduces micro and nanoparticle emissions of even the finest particles up to 99.9 %.

Operating Principle of the EDC Product Line

The waste gases are introduced in a pre-scrubber and following in a tank which is simultaneously storage tank for the scrubbing liquid. The pre-scrubber is equipped with nozzles, which saturate the gas flow with water, and create a turbulent flow. Afterwards, the waste gas is channeled into the electrostatic dust collector tube, where the contained micro and nanoparticles are ionized and precipitated in a grounded water film on the water wall. The filtered fine dust is suspended into the scrubber solution. The dust collector is equipped with an automatic self-cleaning mechanism for the emission electrodes. Remaining residual gases meet the strict German standards for air pollution law (TA Luft).

EDC – Reduction Emissions of Micro and Nanoparticles at the Point-of-Use

As mentioned above, EDC is an electrostatic dust collector for treatment of micro and nanoparticle-containing or aerosol-containing process waste gases up to 90 m³/h as they accrue, for example, in solar cell manufacturing. The dust collector reduces particle emissions of even the finest particles up to 99.9 % and successfully prevents exhaust blockage. It can be used with the most abatement devices and can be equipped with an optional pressure controlled fan and an optional lye supply system. Access for operating and maintenance is from the front and back and operation costs and general safety can be optimized with a process tool interface.

Your Advantages

  • Efficient treatment of particle-containing or aerosol-containing waste gas flows
  • All solid particles suspended in liquid (no dry dust handling)

EDC PLUS – More Reduction of Micro and Nanoparticle Emissions at the Point-of-Use

EDC PLUS is an electrostatic dust collector for treatment of micro and nanoparticle-containing or aerosol-containing process waste gases up to 270 m3/h like how they accrue, for example, in solar cell or flat panel display (FPD/LCD) manufacturing. The dust collector reduces emissions of even the finest micro and nano particle up to 99.9% and successfully prevents exhaust blockage. It can be used with the most abatement devices and can be equipped with an optional pressure controlled fan and an optional lye supply system. Access for operating and maintenance is on front and back and operation costs and general safety can be optimized with a process tool interface.

Your Advantages

  • Efficient treatment of micro and nanoparticle-containing or aerosol-containing waste gas flows
  • All solid particles suspended in liquid (no dry dust handling)
  • Extremely low particle emission
  • Internal back-up during the cleaning process of the electrodes
  • High safety standards (all critical parameters are sensor monitored)
  • Interface to upstream abatement systems

Technical Data

  • Measurements (D × W × H):1500 mm × 1000 mm × 2100 mm
  • Access to maintenance area on front and back side
  • Gas entry: DN150
  • Gas outlet: DN200
  • Gas flows: max. 270 m³/h
