Systems and methods for removal of particulate matter in a filtration system

A filter assembly for use in a particulate filtration system, the system including a housing divided into a first plenum and a second plenum by a tube sheet with the first plenum in fluid communication with an inlet and the second plenum in fluid communication with an outlet, the tube sheet defining an aperture extending between the first plenum and the second plenum, the system further including a discharge electrode coupled to a first electric potential, the filter assembly comprising:

• a support frame having a first end that is adapted to couple to the tube sheet at an aperture and a second end;
• a fabric filter media positioned around the periphery of the support frame;
• a pre-collector body component comprising a substantially continuous sidewall surface, an open first end, and a closed second end, said open first end coupled to the second end of the support frame, the pre-collector body component being electrically coupled to a second electric potential;
• and
• means for cooling the pre-collector body component;
• wherein the difference in the first electric potential and the second electric potential is operable to cause at least a portion of the particulates in the first plenum to collect on the pre-collector body component.

A method for removing particulates suspended in a fluid flowing through a housing, the housing divided into a first plenum and a second plenum by a tube sheet, the first plenum in fluid communication with an inlet, the second plenum in fluid communication with an outlet, the tube sheet defining an aperture extending between the first plenum and the second plenum, the method comprising:

• providing a fabric filter element having a first end sealingly coupled to the tube sheet and adjacent the aperture, the fabric filter element extending from the tube sheet into the first plenum;
• providing a pre-collector body component located upstream of the fabric filter element, said pre-collector body component comprising a substantially continuous sidewall surface, an open first end, and a closed second end, said open first end of said pre-collector body component connected to said second end of said filter element;
• cooling the pre-collector body component;
• providing a discharge electrode;
• and
• coupling the pre-collector body component to a first electric potential and the discharge electrode to a second electric potential wherein the first electric potential and the second electric potential are different so that at least a portion of the particles suspended in the fluid moving between the pre-collector body component and discharge electrode are attracted to one of the pre-collector body component or discharge electrode and any remaining particles are removed from the fluid as the fluid passes through the fabric filter element.
