CONTROL OF GROUNDED SURFACE GEOMETRY IN ELECTROSTATICALLY ENHANCED FABRIC FILTERS

摘要

An electrostatic filter assembly configured to be installed in equipment for removing particulate matter entrained within a gas stream. The filter assembly functions in the removal and collection of the particulate matter from the gas stream. The equipment for removing particulate matter includes a high voltage discharge electrode for imparting an electric charge to the particulate matter whereby an electrical field is produced at the filter assembly. The filter assembly includes a filter element and a supporting structure for the filter element. The supporting structure is configured to establish at the filter assembly, under the operating conditions of the equipment for removing particulate matter, an electrical field having an intensity that produces no more than a selected amount of degradation at the filter element during operation of the equipment for removing particulate matter. Also a method of manufacturing such an electrostatic filter assembly.
