| 摘要 |
<p>The invention relates to a method and to an apparatus for cleansing or purifying dust-laden gases, particularly hot process gases, with the aid of an electrostatic filter device (1; 1') which includes at least one emission electrode (5; 5') and at least one collector electrode (7; 7', 20). There is used a granular material (8) which passes along the collector electrode and which cleanses the surfaces thereof. At the same time, dust collected on the collector electrode is carried away from the filter device together with the granular material. The granular material (8) moves down the collector electrode (7; 7', 20) under the influence of gravity. The granular material (8) is cleansed and recycled to the filter device (1; 1').</p> |
