This denitration apparatus is an apparatus that passes exhaust gas through a catalyst packed bed and removes NOx by a catalytic reaction.

きる。According to the configuration of the present invention as described above,
The following effects can be obtained. (A) The fluidized bed reactor can be rotated in the atmosphere of the engine exhaust gas, so that the fluidized bed can be a centrifugal fluidized bed. Therefore, the fluidized gas linear velocity is larger than that of a conventional fluidized bed in a gravitational field. Since the amount of exhaust gas can be increased, the entire apparatus can be reduced in size and can be mounted on an automobile or the like, and the pollution problem caused by exhaust gas can be rationally solved. (B) By using the rotational power of the engine as the drive source before the fluidized bed reaction, the amount of exhaust gas corresponding to the engine speed can be efficiently processed. ( C ) The pressure loss of the device can be reduced by the current plate.
