Embodiment Construction

[0015] A post-processing exhaust gas circulation high-temperature fan, including a casing 1, an impeller 2, a main shaft 3, a pedestal 4, and a main shaft seal 5. A sub-front disc 6 is arranged between the front disc and the rear disc of the impeller, and a conical surface is used for the assembly of the main shaft and the hub. Combining, make a groove on the end face of the hub, and use the wedge key 7 to lock the radial hole of the main shaft and the end face groove of the hub.

[0016] The main shaft seal adopts the method of labyrinth and carbon ring seal 8, and is equipped with nitrogen seal 9. The nitrogen seal is arranged between the front and rear two labyrinth plus carbon ring seals. The pedestal 4 adopts an integral pedestal. A casing expansion guiding device 10 is arranged between the rear end of the casing and the pedestal.

[0017] The casing expansion guide device includes a flat plate 11 vertically connected to the casing 1, a U-shaped groove body 12 connected...
