Activated carbon discharging device of activated coke desulfurization and denitrification system

Abstract

The utility model discloses an activated carbon discharging device of an activated coke desulfurization and denitrification system, and belongs to the technical field of metallurgical flue gas treatment. The device comprises a screening mechanism, a conveying belt, a surge bin and a scraper, an obtuse included angle is formed between the screening mechanism and an activated carbon discharging area of the activated coke desulfurization and denitrification system, an activated carbon inlet is formed in the top end, an activated carbon outlet is formed in the bottom end, and the screening mechanism comprises a plurality of rotating rolling shafts which are axially and horizontally distributed at intervals; the conveying belt is arranged on one side of the bottom end of the screening mechanism and used for bearing activated carbon. The surge bin is arranged below the conveyor belt, an inlet of the surge bin faces the conveying tail end of the conveyor belt, and an outlet of the surge bin is provided with a gate valve; the scraper is arranged below the surge bin, and an inlet of the scraper is right opposite to an outlet of the surge bin. According to the utility model, the functions of effectively separating granular active carbon from harmful powder and regulating and controlling the circulating speed of an active coke desulfurization and denitrification system can be realized.
