A two-stage granular moving-bed filter includes a gas inlet part, a gas outlet part, and a plurality of flow-corrective elements. The gas outlet part is disposed opposite to the gas inlet part, and the plurality of flow-corrective elements is disposed in a channel formed between the gas inlet part and gas outlet part. Meanwhile, a first granular material is provided to flow through a channel formed between the gas inlet part and the flow-corrective element in a state of mass flow, and a second granular material is provided to flow through a channel formed between the flow-corrective element and the gas outlet part. By means of having two different kinds of filter media moving through the channels between the gas inlet and outlet part, it is capable of performing two-stage filtering process after the raw gas flows therethrough, so as to improve the filtering effect of the gas.

A dust filter has adjustable sub-blades between blades. By adjusting the blades distanced and the sub-blades' positions and angles, stagnation area of filtration material on the blades are removed. Furthermore, space in the dust filter is fully used. Thus, a filtering efficiency is improved.
