Cleaning steps of dust bag in asphalt mixing plant

July 15, 2022

1: Using high-frequency vibration, the larger dust particles entering the filter bag wall will be removed as much as possible, and the entanglement fastness of the fibers will not be affected, and the filter bag has good peeling resistance.

2: Chemical experimental treatment: Extract the bag samples, use professional instruments to test the oil pollution components of the filter bags, so as to select the appropriate washing raw materials, and maximize the cleaning method of the filter bags without causing any damage to the filter bags.

3: Cleaning: Select appropriate washing raw materials and strictly proportion, low temperature water cleaning, uniform water flow, moderate strength, and no mechanical damage to the filter bag.

4: Drying: use hot air drying at about 110 °C to maintain the dimensional stability of the filter bag, and the filter bag will not be deformed or retracted after drying.
5. Repair: Repair the damaged filter bags caused by abrasion, holes, etc. due to use to ensure a high recycling rate.
6: Detection: use the instrument to test the physical indicators of the cleaned filter bag to ensure that the cleaning quality meets the requirements. After the treatment and cleaning of the above procedures, the filter bag can fully meet the requirements of use.
7: Packing, generally a bundle of 10 cloth bags, a bundle of 4, and a bundle of 40.
