Abstract
The report gives results of a feasibility study of the application of charged droplet scrubbing for fine particle control. Results, using the TRW charged droplet scrubber, indicated that the method is feasible and applicable over a wide range of conditions. In the charged droplet scrubber the electrical interaction mechanisms exist in addition to the normal impact and diffusional scrubbing mechanisms. Electrical interaction is strong in the 0.1 to 1.0 micron particulate size range where the normal mechanisms lack effectiveness. Collection efficiencies as high as 80% for 0.1 micron and 90% for 1 micron particles were demonstrated in a three-stage unit. Induced charging or dry charging of particulate by charge transfer from droplets is an effective and major collection mechanism in the fine particulate size range. Large (100 micron) droplets give better performance characteristics than small (10 micron) droplets.
