1. A separating system comprising:
a separating device comprising:
a casing having a gas inlet, a gas outlet, and a discharge port for solid substances;
a rotor disposed in an inside of the casing and 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; and
a plurality of blades disposed between the casing and the rotor and configured to rotate together with the rotor; and
a driving device configured to rotationally drive the rotor, wherein:
the rotor has a first end adjacent to the gas inlet and a second end adjacent to the gas outlet,
each of the plurality of blades has a first end adjacent to the gas inlet and a second end adjacent to the gas outlet,
the casing includes a space between the second end of each of the plurality of blades and the discharge port in the axial direction,
an entirety of the rotor is disposed in the inside of the casing,
in the axial direction of the casing, the first end and the second end of the rotor are apart from the casing,
the separating device further comprises a rectifying structure disposed between the gas inlet and the rotor on the inside of the casing and configured to rectify a flow of a gas flowing into the gas inlet,
the casing includes a casing body, a first end part, a second end part, and an outlet duct part,
the first end part, the casing body, and the second end part are aligned in an order of the first end part, the casing body, and the second end part in the axial direction of the casing,
in the casing, the first end part includes the gas inlet, the outlet duct part includes the gas outlet, and the casing body includes the discharge port,
the second end part includes an inside space in communicative connection with an inside space of the casing body,
the second end part has a bottomed cylindrical shape having a disk-shaped bottom part and a peripheral wall having a cylindrical shape,
the peripheral wall of the second end part includes an opening through which a gas flows out,
the outlet duct part is connected to a peripheral edge of the opening at an outer peripheral surface of the second end part,
the first end part includes:
a small diameter part including the gas inlet and having a bottomed cylindrical shape; and
an expanding diameter part connected to the small diameter part and the casing body,
an outer diameter and an inner diameter of the small diameter part are respectively smaller than an outer diameter and an inner diameter of the casing body,
the gas inlet is formed in the small diameter part,
the expanding diameter part has a taper cylindrical shape,
an outer diameter and an inner diameter of the expanding diameter part gradually increases toward the casing body as a distance from the small diameter part increases in the axial direction of the casing,
the rectifying structure has a circular truncated cone shape and is disposed between the small diameter part and the casing body on an inner side of the expanding diameter part,
the rectifying structure is disposed such that a central axis of the rectifying structure coincides with a central axis of the casing,
the casing body includes a plurality of discharge ports,
the plurality of discharge ports includes the discharge port, and
the plurality of discharge ports are aligned in a circumferential direction along an outer peripheral edge of the casing, and
the driving device is disposed in the inside of the casing.
