Description

Closed built-in cylinder reverse air flow synergistic collision filter cylinder ash removal system Technical Field The invention relates to the technical field of dust treatment equipment, in particular to a closed type built-in cylinder reverse air flow synergistic collision filter cylinder ash removal system. Background According to different ash removing mechanisms, the existing ash removing modes of the filter screen can be divided into two main types of mechanical vibration and air flow back blowing. Mechanical vibration ash removal mainly causes dust on the surface of a filter screen to fall off by means of shaking, vibration with higher frequency and smaller amplitude, and the like, but the mechanical ash removal mode is easy to damage the structure of the filter cylinder. The air flow ash removing method is to make the filter cylinder expand and contract to shake off the accumulated dust by using the back blowing air flow. The existing airflow ash removal has the following common forms of back airflow ash removal, air ring back blowing ash removal, rotary back blowing ash removal and pulse blowing ash removal, and compared with a mechanical ash removal mode, the airflow ash removal has the advantages of large treatment air quantity, good ash removal effect, stable work, small damage to filter bags and the like. However, the air flow ash removing method has some disadvantages, such as that the filter cylinder needs to stop working to affect the working efficiency of the filter cylinder when ash is removed, the filter screen is damaged due to the fact that the air flow is impacted too hard to affect the service life of the filter cylinder, and the range of the filter cylinder far away from the air flow air inlet is poor in ash removing effect, and all parts of the filter cylinder cannot be uniformly ash removed, so that manual ash removal is needed.
