Abstract: The collection efficiency for the particle larger than 1μm decreases due to the re-entrainment on an electrostatic precipitator (ESP) for carbon particles. The re-entrainment means that particles on collecting electrodes refly to gas flow, The re-entrainment may be prevented by increasing the adhesive force between particles and collecting electrodes.In this work, we have investigated the prevention of re-entrainment by spraying water with surfactant into the gas flow. Diesel exhaust particles were used as particulate matter for the experiments. The particle concentration was measured using a scanning electron microscope which is able to count the particle lager than 0.01μm. As a result, collection efficiency was improved by spraying water with surfactant into ESP. The results indicate that re-entrainment and particle agglomeration on collecting electrode are prevented.
