Exhaust handling system for marine vessels
The patent US12043361B1 describes an innovative exhaust handling system designed for marine vessels. This system includes a cap that is affixed to the top of an exhaust stack, creating an enclosure around the outlet of an exhaust pipe. The design features a collection pipe that is in fluid communication with the cap, allowing it to receive exhaust from the enclosure. Additionally, the system incorporates a coupling that connects the collection pipe to an exhaust cleaning assembly, which contains at least one tank for exhaust reception. The cap and collection pipe together facilitate two distinct flow paths for exhaust: one leading to the atmosphere and another directing it to the cleaning assembly.
Further enhancements to the system include a pressure-actuated vent connected to the cap, which can selectively release exhaust to the atmosphere. The vent may feature valve members, such as rotatable louvers, to control exhaust emission. The collection pipe is designed for flexibility and includes a cleanout port for maintenance access. The patent also outlines methods for operating the system, including connecting the exhaust cleaning assembly while the vessel is docked and managing exhaust flow during vessel operation. Overall, the claims emphasize the system's structural integrity, operational efficiency, and maintenance accessibility, contributing to improved exhaust management in marine environments.
