A separating device includes a casing, a rotor, and a blade. The casing has a gas inlet, a gas outlet, and a discharge port for solid substances. The rotor is disposed on an inner side of the casing and is configured to be rotatable around a central axis of rotation of the rotor, the central axis of rotation extending along an axial direction of the casing. The blade is disposed between the casing and the rotor and is configured to rotate together with the rotor. The blade has a first end adjacent to the gas inlet and a second end adjacent to the gas outlet. The casing has a space between the second end of the blade and the discharge port in the axial direction.
