Fig. 1 shows a dust collection and discharging device provided in this embodiment, which is used for collecting smoke dust in smoke gas of a rotary reduction furnace. The dust collection and discharging device comprises a bin body 1, a conveying mechanism and a discharging mechanism.
The inlet end of the feed bin body 1 is suitable for being communicated with the rotary reduction furnace, and the feed bin body 1 is provided with an air inlet 4 for introducing cooling gas into the feed bin body, and the cooling gas in the embodiment selects hydrogen because the hydrogen in the flue gas needs to be recovered. Specifically, the inlet end of the feed bin body 1 is communicated with an air inlet pipeline 2 and an air outlet pipeline 3, and the air inlet pipeline 2 and the air outlet pipeline 3 are arranged in a downward inclined mode towards the inlet of the feed bin body 1. By obliquely arranging the air inlet pipeline 2 and the air outlet pipeline 3, when the flue gas enters from the air inlet pipeline 2, the smoke dust in the flue gas can be settled on the lower side wall of the air inlet pipeline 2 under the gravity of the smoke dust along with the flow of the flue gas; when the flue gas enters the air outlet pipeline 3 through the air inlet pipeline 2, smoke dust in the flue gas can also subside to the lower side wall of the air outlet pipeline 3 under the self gravity. The smoke dust which is settled on the air inlet pipeline 2 and the air outlet pipeline 3 can slide into the stock bin body 1 from the inclined pipe wall under the action of self gravity, so that the dust collection efficiency is improved. In order to reduce the flow rate of the flue gas when the flue gas flows out, the inner diameter of the air inlet pipeline is not larger than the inner diameter of the air outlet pipeline 3. By increasing the inner diameter of the air outlet pipeline 3, the flow velocity of the smoke in the air outlet pipeline 3 is further reduced, the sedimentation of the smoke in the air outlet pipeline 3 is increased, and the cleaning degree of the smoke after dust collection is improved.
The conveying mechanism is arranged at the bottom of the stock bin body 1. The outlet end of the conveying mechanism extends in a direction away from the silo body 1. The conveying mechanism is arranged vertically to the stock bin body 1.
