EDC - Point of Use Waste Gas Treatment of ultrafine particles

The waste gases are introduced in a pre-scrubber and following in a tank which also contains 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 tubes, where the contained micro and nanoparticles are ionised and precipitated in a grounded water film on the water wall. The filtered fine dust is suspended into the scrubber liquid. The dust collector is equipped with an automatic self-cleaning mechanism for the emission electrodes and has an internal backup function: while one column group is being cleaned automatically, the other groups continue the treatment to ensure uninterrupted operation. Remaining residual gases meet the strict German standards for air pollution law (TA Luft).
