<p>A dust separation apparatus including a cyclone consisting of three sections, a first cylindrical section provided with a tangentially located inlet duct for dust-loaded waste gases, a second cylindrical section therebelow, and below that a third cone-shaped section. According to the invention, a rotor is located in the second section, which rotor carries outside its periphery one or more emission electrodes. A scraping device is provided outside the rotor to scrape accumulated dust from the inner surface of the second section, which surface acts as a precipitation electrode for dust particles charged by the emission electrode or electrodes.</p> |
