Description
Technical Field

[0002] In sintering production, the role of electrostatic precipitator is to use the force of electric charge to capture and remove particulate matter in the flue gas. The dust layer adsorbed on the electrode plate falls into the ash hopper below through vibration for centralized discharge. In this process, the dust enters the ash hopper with the airflow. The airflow contains a certain amount of humidity. When the humidity is high, it will cause the ash hopper to form a humid environment. The agglomerates in the ash hopper first begin to form from the low-temperature silo wall, and then begin to spread to the dust removal ash in the silo, thereby reducing the fluidity of the dust removal ash in the ash hopper and causing adhesion and agglomeration. In addition, due to the high alkalinity sintering mode, part of the calcium oxide will be The dust contains volatile fuel, which is a flammable substance that will undergo secondary combustion under certain temperature conditions, further forming solid lumps of dust. When there are too many lumps, the dust can only be shut down for processing, and then airborne workers will manually shovel the dust away. The efficiency of manual shoveling is extremely low, which is not only labor-intensive but also has safety hazards. Therefore, a lump cleaning device is needed, which is required to efficiently clean the lumps on the inner wall of the ash bin, thereby ensuring the normal operation of the ash bin and reducing the labor intensity of the workers.
