[0004] In the process of realizing the utility model, the inventors found that at least the following problems in the prior art have not been solved: by setting up a cyclone dust collector for performing solid-gas separation operations on flue gas, the flue gas enters the cyclone dust collector, and the flue gas first acts on the baffle, pushing the baffle, thereby driving the cleaning rod, so that the cleaning brush cleans the inner wall of the cyclone dust collector to prevent dust from adhering to the inner wall of the cyclone dust collector, which is beneficial to extending the service life of the cyclone dust collector. However, in the above case, during use, the smoke and dust generated by the cleaning brush cleaning the inner wall of the cyclone dust collector is easily discharged through the exhaust pipe with the airflow, which is not conducive to the dust removal operation of the cyclone dust collector on the flue gas.

[0005] Therefore, we propose a kiln flue gas environmental protection treatment device that can solve the above problems. Utility Model Content
