The dust-laden gas enters the ash hopper after passing through the air outlet, where some larger dust particles and aggregated dust clumps fall directly due to inertia, serving as a preliminary dust collection. The airflow entering the ash hopper turns upwards and fills the chamber. As it passes through the pulse pleated filter bags, the dust is trapped on the outer surface of the filter sleeves. The purified gas then enters the clean chamber above the filter bags and is collected into the exhaust duct.
When the set value is reached or the time is up, the dedusting control instrument emits a cleaning command to remove dust from the filter bag surface, which then falls into the ash hopper. The entire process includes filtration, pulse cleaning, and exhaust. The cleaning of the dust collector is accomplished by the pulse electromagnetic valve and control instrument, with proper cleaning ensuring the service life of the filter cartridges. As the dust collector operates, with continuous filtration, the dust accumulated on the outside of the filter bags gradually increases, and the resistance of the dust collector also gradually rises.
Performance characteristics of pleated dust collector bags:
1. Suitable for a variety of operating conditions, especially for industries with high dust concentrations.
2. The filter bags feature an integrated design with strong sealing, making installation and replacement easy, and reducing downtime.
3. The dust removal core components use pleated filter bags, featuring a compact structure and space-saving design.
4. An alternative solution for traditional bag dust collectors and electrostatic precipitators.
5. The filter bags feature surface filtration, offering good filtration efficiency.
6. Compared to bag dust collectors, pleated bag dust collectors have a simpler structure, significantly increasing the filtering area, which can be about 2.5-3 times larger than the original, with good filtration efficiency.
