    摘要: A filter assembly (100) and a filtration system (10) for removing particulate matter from a stream of gas or other fluid are presented. The system includes a housing (20) that is divided into a first plenum (30) and a second plenum (40) by a tube sheet (50). The tube sheet (50) is substantially planar, and a plurality of apertures (90) extend through the sheet (50). The tube sheet (50) supports a plurality of filter assemblies (100). A filter assembly (100) includes a pre-collector body component (130) that is coupled to an end of a filter element (120) and that is electrically coupled to a first electric potential. The system (10) also includes a discharge electrode (160) that is coupled to a second electric potential. In operation, at least a portion of the particulate laden gas will pass adjacent to the pre-collector body component (130) and discharge electrode (160) before entering the filter element (120). When the gas passes the pre-collector body components (130) and discharge electrodes (160), the difference in electric potential between the body component (130) and the discharge electrode (160) causes at least a portion of the particulate matter to gather at the body components (130) thereby decreasing the amount of particles presented to the filter element.
