Abstract:
An electric dust collecting apparatus comprising:at least one needle electrode configured to charge floating particles in air by generating corona discharge around needle points;at least one collecting electrode provided on cell arrangement corresponding to the needle electrodes and configured to attract and collect the charged floating particles by an electrostatic force; andat least one deflection electrode comprising a continuous sheet of metal having a front plate portion with a mounting hole therein, a plurality of side plate portions, said sheet of metal being bent such that said plurality of side plate portions are substantially perpendicular to said face portion and edges of said plurality of side plate portions become adjacent to one another so as to form a rectangularly hollow longitudinal structure, said needle electrode being fixed in said mounting hole;wherein said deflection electrode applies a deflection force to the charged floating particles to move said charged floating particles toward the collecting electrodes by a potential applied from the side plate portions.
