Abstract
Method and device for agglomerating particles of opposite electrical charge suspended in gas streams, in which two partial gas streams (3) are provided, in which the particles are alternatingly charged with positive and negative ions in a manner such that sequences of particle clouds (7, 8) with alternatingly positive and negative charge are generated locally, and that the two partial gas streams (3) are brought together in a manner such that the particle clouds (7, 8) of opposite charge impinge on each other and the particles of different sign conglomerate into larger particles. Two corona discharge devices consisting of a point (5) and plate (6) are fed by two transformers wired in opposite phase.
