This application provides a high-temperature flue gas inertial separation device, including a separation container, an isolation component, an air inlet component, and an air outlet component. The isolation component is disposed within the separation container and divides its internal cavity into a connected air inlet chamber and an air outlet chamber. The air inlet component is disposed within the separation container and communicates with the air inlet chamber, and the air outlet component is disposed within the separation component and communicates with the air outlet chamber.

This significantly improves the collection efficiency of fine particles while reducing dependence on a single high flow velocity, thus reducing pressure loss and equipment wear.
