<p>PURPOSE: To enable efficient purification by regulating the distances between ionizing electrodes or the like and collector surfaces and the differences in the state of charge between the collector surfaces and charged impurities in such a manner that impurity particles are carried approximately rectilinearly to the collector surfaces by an ion beam and are adhered thereto. CONSTITUTION: Air, flue gases or the like are introduced to a duct or the like and are ionized. The charged impurity particles 7 existing in the air flue gases or the like are attracted to the one or >=2 collector surfaces 2 by the differences in the state of charge and are adhered to the surfaces 2. At this time, the distances between the one or >=2 ionizing electrodes 5 or the like directed toward the collector surfaces 2 and the collector surfaces 2 and the differences in the state of charge between the collector surfaces 2 and the charged impurity particles 7 described above are regulated to direct the impurity particles 7 approximately rectilinearly toward the collector surfaces 2 by the ion beam and to adhere the impurity particles thereto. Consequently, the efficient purification is executed even if a duct is short.</p> |
