Abstract

Abstract The present invention relates to an improved construction for an electrostatic precipitator having ladder bar spacers. The electrostatic precipitator collects solid particles carried by a flue gas from a source of combustion. The precipitator includes a plurality of spaced plates for collecting solid particles from the flue gas by electrostatic attraction of the solid particles to the plates. A second plurality of elongated electrodes is positioned among the plates. Each of the electrodes is mounted between a pair of adjacent plates. Each of the electrodes is parallel to the other electrodes and is parallel to the plates. A third plurality of ladder bars is positioned between adjacent plates to hold the plates in a flat attitude and to maintain adjacent surfaces of adjacent plates substantially equidistantly spaced from one another. Each of the ladder bars has a connector bar secured to one of the pair of adjacent surfaces. Each of the ladder bars has a fourth plurality of holder bars. Each of the holder bars having one end connected to its respective connector bar and extending outwardly from the connector bar toward the other of the pair of adjacent surfaces. A contact on the other end of each holder bar engages the other of the pair of adjacent surfaces to hold the pair of adjacent surfaces apart.
