In order to ensure that ship exhaust meets emission standards, ship exhaust needs to be filtered and treated by a treatment device before it can be discharged.

[0003] According to a Chinese patent with the announcement number CN216935145U, a ship exhaust treatment device for official ships is disclosed. The utility model is provided with an exhaust pipe, a support shaft, fan blades, a cylinder, a support block, a support rod, a spring, a scraper and other structures. When the exhaust gas passes through the exhaust pipe, the airflow drives the fan blades to rotate, and then the support shaft rotates, and the support shaft drives the cylinder to rotate, and then the scraper scratches the inner wall of the exhaust pipe, making the inner wall of the exhaust pipe easy to clean.
