Example Embodiment
[0009] Specific implementation one: as figure 1 As shown, the stepped differential fluidized bed cooler in this embodiment includes a fluidized bed body 1, a feed pipe 5, an exhaust pipe 6, a first discharge pipe 8, a plurality of second discharge pipes 9, and a plurality of second discharge pipes 9. A plurality of air chambers 10, a plurality of air distribution plates 2, a plurality of air caps 3 and a plurality of overflow plates 7, one end of the feed pipe 5 is installed on the side wall of one end of the fluidized bed main body 1 and is connected with the fluidized bed main body. 1 is connected to the inner cavity of the fluidized bed body 1, and an exhaust pipe 6 and a first discharge pipe 8 are arranged from top to bottom on the outer side wall of the other end of the fluidized bed main body 1. The exhaust pipe 6 and the first discharge pipe 8 They are all communicated with the inner cavity of the fluidized bed main body 1, the plurality of air chambers 10 are arranged ...
Example Embodiment
[0011] Specific implementation two: as figure 1 As shown, the height difference H1 between two adjacent air distribution boards 2 in this embodiment is 180-550 mm. This design ensures that there is a height difference between adjacent fluidized sub-beds, and the fluidized material enters the next stage smoothly. Other components and connection relationships are the same as in the first embodiment.
Example Embodiment
[0012] Specific implementation three: as figure 1 As shown, the height difference H2 between the air caps 3 on two adjacent air distribution panels 2 in this embodiment is 200-500 mm. This design ensures the fluidization height of the adjacent fluidized sub-beds and prevents the exchange and back-mixing of particles in the adjacent fluidized sub-beds. Other compositions and connection relationships are the same as in the first or second embodiment.
