The bag filter of asphalt concrete mixing plant is a common industrial dust removal equipment, and its working principle is as follows:
Dust collection: The dust generated by the asphalt concrete mixing plant is guided through pipelines to the interior of the bag dust collector.
Filter dust: After the dust enters the bag filter, it is filtered through the filter material on the surface of the bag. The fabric bag material is usually polyester fiber, polyester fiber polyester needle felt, etc. Its fine and dense fiber structure can effectively capture dust particles.
Dust deposition: After being captured by the filter bag, dust particles gradually deposit on the surface of the cloth bag under the action of gravity.
Dust removal process: Over time, dust gradually accumulates on the surface of the bag, which can affect the filtering effect of the dust collector. In order to maintain the efficiency of the dust collector, it is necessary to carry out dust removal operations. The dust removal process usually uses pulse blowing, which uses compressed air to inject pulse airflow into the interior of the cloth bag, causing it to vibrate, thereby shaking and removing dust.
Collection and processing of dust: The dust that falls during the dust removal process is collected and discharged from the dust collector through pipelines, and then further processing is carried out, such as collecting it into a dust bin or dust treatment equipment.
