Technical Field
[0001] The utility model relates to the technical field of pulse bag dust collector equipment, in particular to a high-temperature resistant pulse bag dust collector. Background Art
[0002] Pulse bag dust collector is a common industrial dust removal equipment, mainly used to remove dust in the air. It captures dust particles through bag filtration and uses pulse airflow to regularly clean the dust on the bag to maintain its good filtration performance. Pulse bag dust collector is suitable for dust generated in various industrial production processes, especially in situations with high air volume and high dust concentration.
[0003] The pulse bag dust collector can effectively capture fine dust particles. However, when used in a high-temperature working environment, the filter bag's fixing cage will be deformed or damaged due to the high temperature, causing the shape of the filter bag to change, reducing the filter bag's dust filtering effect. At the same time, when the filter bag cannot completely clean the dust on the inner wall of the filter bag due to the backflush pipe, the staff's maintenance efficiency of the filter bag is low.
