| 摘要 |
The invention relates to a gas-filtering device using a wet electrostatic filter, comprising at least one ionising electrode 5 inserted between two or more collecting electrodes made from incombustible synthetic or metal fabric 4 which suppress the preferential currents upon passage of the scrubbing (washing) liquid 3. A high-voltage generator 8 supplies the ionising electrodes 5 which may be subject to electrical arcs which will be detected immediately by an electronic system 9, 10, 12, 13 connected to an optical fibre 11. <IMAGE>
