Claims

[Scope of utility model registration request]

Connecting a heat exchanger below or an introduction duct for guiding gas upward from the outside in the circumferential direction or tangential direction to a part of a cylinder having a nearly horizontal axis and equipped with a powder separation chamber. As a result, a swirling flow moving approximately horizontally is formed in the cylinder, and a powder supply chute is connected to the introduction duct, and a powder discharge chute is connected to the powder separation chamber. The powder and granules supplied from the powder supply chute to the introduction duct flow into the cylindrical body together with gas, are further separated in the powder separation chamber, and are discharged to the heat exchanger below or to the outside through the powder discharge chute. In this heat exchange unit between powder and gas, a spiral chamber is provided at the end of the gas discharge side of the cylindrical body, and a circular discharge duct is provided on the side wall of the spiral chamber to guide the gas upward to the upper heat exchange device. connected upward in the circumferential or tangential direction, and the discharge duct is connected to a powder supply chute to the upper heat exchange device,
The lower side of the swirl chamber is formed into a hopper shape, and a heat exchanger below or a powder discharge chute to the outside is connected to the lower part of the swirl chamber, so that the powder and granules in the gas flowing into the cylinder are removed from the cylinder. A unit for exchanging powder and gas, characterized in that the powder and granule are separated in a lower hopper attached to a whirlpool chamber in addition to separation in a granule separation chamber attached to the body.
