Precipitator cell

Claim 1

An electrostatic precipitator cell having a plurality of spaced collecting plate electrodes with alternate electrodes adapted to have opposite polarity charges, regularly spaced ones of these electrodes having the same charge of one polarity being projected beyond the remainder of said plates in the direction against the direction of gas flow through the precipitator to form ionizing zones, upper and lower ionizer wire spring support means for receiving, locating and supporting ionizer wires under tension, each said support means formed of electrically conductive resilient sheet material and having a base portion and a cantilevered ionizer support portion extending therefrom along substantially the whole length of each respective base portion, each of the base portions being formed from the respective sheet material as a depending spring clip extending substantially the whole length of the respective base portion, support means spanning more than one of said ionizing zones, said plate electrodes of the other polarity charge being provided with upper and lower inwardly extending edge slots receiving therein respectively the depending spring clip base portion of the respective upper and lower support means in supporting and electrically conductive relation, and a plurality of respective ionizer wires of electrically conductive material each supported in electrically conducting contact with and under tension between the respective upper and lower cantilevered ionizer support portions of said support means, said ionizer wires spanning the respective ionizing zones and charged with the other polarity between said regularly spaced projecting plates of the one polarity charge.
