Cloth bag filter meets the needs of the current environmental protection situation and plays an important role in many industries. In the daily use of bag filter, the dust removal efficiency will decrease with time. At this time, it needs to be cleaned properly. The cleaning methods are as follows:
1. Cleaning method: It is better to use suitable raw material for washing and to mix it strictly. Clean it with low temperature water. The water flow needs to be average and the intensity is moderate, so that the filter bag will not be damaged. Stop repairing broken filter bags to ensure high reuse rate, and damaged parts can contact the original company to provide.
2. Cleaning method: With high frequency vibration, the larger dust particles will enter the filter bag, which will not affect the entanglement fastness of the fibers, and continue to adhere to the good quality of the filter bag and the easy peeling of the dirt.
3. Drug soaking method: select the appropriate chemical agent to soak the dust bag, which can remove the oil stains and dirt in the gap of the filter bag to the maximum extent.
4. Drying method: hot air drying at about 110 C. After drying, the filter bag can adhere to no deformation and no retraction.
5. Quality Inspection and Packaging Method: After strict monitoring, the dust removal bags will be packed separately, affixed with the monitoring certificate, and shipped to the warehouse.
6. Chemical experiment disposal method: extract cloth bag samples, use professional together to test the oil contamination components of the filter bag, so as to select suitable washing materials to clean, to ensure the safety of the filter bag at the maximum level.
7. Final test method: Stop physical index test with the same pair of filter bags after cleaning to ensure that the cleaning quality meets the standard. After cleaning, the indexes of the dust bag returned to normal, and the permeability of the bag returned to normal under the stable condition. How long it will last depends on the customer's dust removal equipment and working environment. For example, the dust bag of asphalt mixing station can be used for one year after cleaning. And we should pay attention to the fact that when cleaning the dust-removing cloth bags, we must find a dozen cleaning factories, so that the cleaning results can be guaranteed.
