Electrostatic precipitator impactor assembly

An electrostatic precipitator which comprises:

• a collecting cell having at least some grounded electrodes, said cell including a frame carrying said electrodes;
• a striker assembly to remove contamination from said collecting cell which includes an elongated first member having a major portion of the mass thereof disposed at a first axial extremity, and means for pivotally mounting said elongated first member at a second axial extremity, said means for pivotally mounting allowing motion of said first axial extremity of said elongated first member between first and second positions, said first position being at a higher elevation than said second position, said first axial extremity of said first elongated member being disposed in contacting relationship with said collecting cell in said second position and spaced apart from said collecting cell in said first position, cam means for urging said elongated first member into said first position, said cam means releasing said elongated first member for movement under the influence of gravity from said first position to said second position in at least one position of said cam means;
• said precipitator further includes an elongated second member having a major portion of the mass thereof disposed at a first axial extremity and means for pivotally mounting said elongated second member at a second axial extremity, said elongated first member and said elongated second member being fixed together in generally coplanar relationship and mounted for movement about a common axis;
• and said collecting cell includes a striker bar extending across said collecting cell.
