A recently granted patent (Publication Number: US11975275B2) discloses a filtering apparatus designed for the fluid intake of a nuclear power generation facility. The apparatus comprises a primary frame with primary filters supported on it, creating a secondary enclosed volume where fluid passes through secondary filters supported on secondary frames. The fluid then flows through enclosed flow passages and exits the apparatus through outlet openings. The secondary filters are cylindrical in shape and are supported by longitudinal beams and hoops within the secondary enclosed volume. Additionally, reinforcing plates are attached to the primary frame to enhance structural integrity.

Furthermore, the patent details various configurations and features of the filtering apparatus, such as the use of perforated sheet metal or mesh screen for the secondary filters, the pore size differences between primary and secondary filters, and the percentage of total surface area occupied by secondary filters compared to primary filters. The secondary filters are designed with polygonal sides, and the primary filters are folded to create corrugations or ridges. The apparatus aims to efficiently filter fluid intake in nuclear power generation facilities, ensuring optimal performance and safety in operation. These innovative design elements and structural features highlight the technical advancements in filtering technology for critical industrial applications like nuclear power generation.
