| 摘要 |
<p>The present invention relates to a device for cleaning of an air stream (40) from electrically charged particles (aerosols), said air stream passing through the device, said device comprising at least two electrode elements (20, 21) that are arranged in planes parallel to each other and at a gap distance (d) between adjacent electrode elements (20, 21), that the electrode elements (20, 21) are connceted to a respective terminal of a high voltage source, and that spacers (11) are provided between adjacent electrode elements (20, 21). It is significant of the device that the spacers (11) constitute electrically insulating material, through which material the air stream may pass, and that the spacers(11) are arranged in such a way that alla ir transport through the device must pass through the spacers (11).</p> |
