Eng. 50:154-156, Hay 1951. ` , ` ; In a sonic agglomeration aerosols--dusts, smokes, fumes, ; } fogs or mists--are subjected to hich-inr.ensity sound. This * sound causes the gas-borne pollutants to vibrate, collide and -i adhere together in clusters of different size for removal freu j ' the gas phase in a secondary separator such as a cyclone. The ,; ' effeciency of sonic agglomeration is dependent upon 1) the .; ' frequency of the sound, 2) the size of particle, 3) the density ** of the particle and 4) the velocity of the gas. Ordinarily, ; only the first two factors are of commercial importance. The ' primary factor of a sonic agglomeration is to agglomerate the aerosol particles into larger particles of sufficient size to permit their removal from the gas in a secondary collection. . Little separation of the pollutants from the gas if effected in the agglomerator itself. The particle collection efficiency / of a sonic agglomeration systeu can be increased by introducing ' a fine spray of mater into the agglomeration chamber. Devices for the generation of sound fall into three Groups : 1) piste.-., 2) ''histle and 3) siren. The piston-type sound generator includes magnetos tricticn'dcvices, electro-magnetic devices and piezoelectric crystals. These aro essentially low out-put devices and have not had large commercial application. 'Thistles have such low efficiencies that they are of no-interest. The V.- siren-type sound generators develop large amounts of power and are being successfully used in commercial application. GARLOCK inc 00058-008973 ATI-179 T t. How to Apply insulation cr.
