| Abstract |
A method and an apparatus for the purification of air, and the like , in which the air is directed into a duct or equivalent, the air is ionized, and the charged impurity particles collector surface by virtue of a difference in the states of charge, causing the particles to means of one or more ionizing electrodes directed at a collector surface. The distance between the ionizing electrode or equivalent and the collector surface as well as the difference between the states of electric charge of the collector surface that the imputrity particles are so adjusted ion beam essentially directly towards the collector surface and settle on it. |
