Abstract
Collector plates for use in the second stage of a two-stage electrostatic ecipitator comprise plates having non-conducting surfaces to which a coating of low conductivity, typically between 300 and 150,000 ohms per square, is affixed. One embodiment of such plates typically comprises a rigid, non-conducting plastic material coated with a material of low conductivity. Another embodiment of the present invention comprises a metallic plate coated with an insulating material of high dielectric strength, typically with a dielectric constant of at least 3000, to which the above mentioned low-conductivity coating is affixed. The collector plates may be mounted in such a manner as to maintain the airflow through the second stage of the precipitator in a direction virtually parallel to the surface of the plates.
