  • Collecting electrode plate assembly
    Patent number: 4240810
    Abstract: A collecting electrode plate assembly for a flow-through housing of an electrical precipitator wherein each collecting electrode is made up of aligned panels interconnected by guide arrangements spanning the junctures of the adjacent panels. Each guide arrangement includes a pair of opposing plates secured to one of the panels and outwardly embracing an adjacent panel to accommodate relative lateral movement between adjacent panels while retaining the panels in a common plane.

  • Rapping assembly and electrode supports for electrostatic precipitators
    Patent number: 4093431
    Abstract: A device for rapping electrode carriers and supporting same within an electrostatic precipitator whereby dust accumulating upon electrodes extending vertically from the electrode carriers are removed. The rapping assembly and electrode support means are suspended from the roof of an electostatic precipitator wherein the electrode support means includes a rapping shaft drive means at the lower end thereof and electrode carrier means. The rapping shaft drive means is in driving relation with a rapping shaft wherein the rapping shaft rotates at a preselected rate and includes a plurality of rapping members attached thereto, each rapping member being disposed to rap each electrode carrier which in turn sends vibrations through the electrodes which extend vertically downwardly from the electrode carriers thereby removing dust accumulating on the electrodes.
