Method For Removal Of Material From The Collecting Plates Of Electrostatic Precipitators And The Like
US Patent:
3984216, Oct 5, 1976
Filed:
Nov 15, 1974
Appl. No.:
5/523991
Inventors:
John J. Smortchevsky - San Francisco CA
International Classification:
B03C 376
US Classification:
55 13
Abstract:
An improved method for effective removal of collected materials, such as dust and fly ash, from the collecting plates of electrostatic precipitators and the like which induces simultaneous axial and transverse vibratory motions in each collecting plate with substantial coincidence of the maximum accelerations associated with the two motions. A natural frequency of the axial vibration 2n times the natural frequency of the transverse vibration for values of n in the range of 1 to 5 is most advantageous for material removal.
