A New Electrostatic Eliminator Using High Voltage Usable in Explosive Atmosphere

Abstract The safe performance of a new electrostatic eliminator was examined experimentally in inflammable gas (ethylene)-air mixtures. The resistive-coupled electrode produced ion-pairs safely for reducing static charges, and incendiary discharges were suppressed by the resistor and voltage supplied to the electrode. The performance of the new eliminator (flange-type) driven with an AC (50Hz) or DC high-voltage power source was evaluated with a full-size pneumatic powder-transport system. It was confirmed that the new eliminator is effective for reducing electrostatic charges from polymer materials
