Document Type and Number:
Japanese Patent JP7402481
Kind Code:
B2
Abstract:
To provide a dry separation method and a dry separation device which can suppress clogging of a gas disperser, and are environment-friendly at low cost.SOLUTION: A dry separation method of the present invention for introducing gas into a body having a fluidized layer and separating a separation object in the fluidized layer includes steps of: introducing the gas through a hole having a throttling function; fluidizing a fluidized medium or powder serving as the separation object by the gas introduced through the hole to form the fluidized layer; and recovering the separation object separated by the fluidization. In a preferable embodiment of the dry separation method, a flow rate of the gas passing through the hole is represented by Uor and a terminal settling rate of the powder is represented by Ut, the relationship of Uor>Ut is satisfied.SELECTED DRAWING: Figure 1
