Superfine powder recovery device

The utility model discloses a superfine powder recovery device for recovering glass micro-beads discharged along with flue gas. The superfine powder recovery device comprises a guide pipeline, an exhaust pipeline and a recovery mechanism, wherein the guide pipeline comprises an inlet and an outlet and is used for conveying the flue gas and the glass micro-beads; the top of the exhaust pipeline is connected with the outlet of the guide pipeline, and a recovery outlet is formed in the bottom of the exhaust pipeline; the exhaust pipeline is arranged outside the outlet of the guide pipeline to form a chamber for receiving the flue gas, and used for discharging the flue gas conveyed from the guide pipeline; the recovery mechanism is connected with the recovery outlet of the exhaust pipeline and used for recovering the glass micro-beads discharged from the outlet of the guide pipeline. The superfine powder recovery device is capable of separating the glass micro-beads from the flue gas and recovering the glass micro-beads discharged along with the flue gas, so that the yield and the economic benefit can be increased; meanwhile, the pollution on the environment can be reduced and the trouble of manual frequent clearing is avoided.
