[0002] High titanium slag is a titanium ore enrichment object formed through a physical production process, and is commonly referred to as high titanium slag. High titanium slag smelting is usually performed in a low-power or semi-closed furnace. A large amount of gas is generated during the smelting process. The flue gas contains not only a large amount of smoke dust but also a large amount of heat energy. Therefore, the heat energy in the flue gas is generally recovered at the present stage. However, when the waste heat in the flue gas is recovered, a large amount of smoke dust contained in the flue gas can block the filter screen installed in the waste heat recovery equipment or adhere to the outside of the heat absorption pipe, resulting in a significant reduction in the heat absorption effect. In the prior art, the smoke dust adhering to the filter screen needs to be cleaned manually, which is very inconvenient. SUMMARY
