Description
Technical Field
[0001] The invention relates to the technical field of dust bag collector ash hopper transmission, in particular to a conveying device for dust accumulation in the ash hopper of a dust bag collector. Background Art
[0002] Bag dust collectors are core equipment for industrial flue gas purification. The problem of dust accumulation and compaction in the ash hopper of bag dust collectors has long restricted the efficiency and stability of the system. Due to humidity, temperature fluctuations, and electrostatic adsorption, dust inside the hopper easily forms a dense, compacted layer, resulting in poor ash discharge and distorted material level monitoring. In severe cases, it can cause structural deformation or even collapse of the hopper. Traditional anti-compaction technologies have the following significant drawbacks:
[0003] Mechanical vibration technology: Using a single-direction impact hammer or vibration motor, the energy transfer is linearly attenuated and can only act on a local area. The high-frequency impact can easily cause fatigue cracking of the hopper weld.
[0004] Air cannon clearing: It relies on the instantaneous impact of pulsed airflow, with energy consumption as high as 2-5kW / time, and has insufficient penetration into the deep-layered compacted layer, posing a risk of compressed air leakage.
[0005] Fluidizing air device: It is necessary to continuously inject high-pressure gas to maintain the fluidization of the ash layer, which not only increases the load of the dust removal system, but also changes the flue gas dew point and causes secondary compaction.
[0006] Therefore, it is necessary to design a conveying device for the dust accumulation in the ash hopper of a bag filter to prevent the dust accumulation in the ash hopper from compacting and to improve the cleaning and conveying effect of the dust accumulation in the ash hopper.
