What measures can be taken to prevent bag dust collectors from falling off?
Jul 29,2025
During the operation of bag filters, bag shedding is a common problem that affects equipment efficiency and production safety. Dropping bags not only leads to a decrease in dust removal efficiency and dust leakage, but may also damage internal components of the equipment. Based on industry experience, the following are key measures to prevent bag dust collectors from falling off:
1、 Optimize the installation process of filter bags
The firmness of the connection between the filter bag, flower board, and skeleton directly affects whether the bag falls off. During installation, it is necessary to ensure that the elastic ring of the filter bag is fully embedded in the sealing groove of the flower plate hole to avoid loosening due to insufficient insertion or positional deviation. At the same time, when the filter bag is placed on the skeleton, it should be kept vertical to avoid tilting and causing excessive local stress. Especially, attention should be paid to whether the welding points at both ends of the skeleton are smooth to prevent puncturing the filter bag or hindering installation in place. For large dust collectors, it is recommended to check the fixing of the filter bags one by one after installation, and if necessary, use specialized tools to assist in fastening.
2、 Select high-quality accessories and conduct regular inspections
1. Filter bag and skeleton: Choose filter bags and skeletons that are compatible with materials and have precise dimensions. The verticality error of the skeleton should be controlled within the allowable range to avoid uneven stress on the filter bag due to bending; The elastic material at the mouth of the filter bag needs to have good fatigue resistance to prevent elastic attenuation and detachment after long-term use.
2. Dust removal device: Excessive dust removal force or improper frequency is an important cause of bag dropping. Adjust the cleaning parameters according to the characteristics of the dust, such as the injection pressure and time of the pulse valve, to avoid tearing off the filter bag due to excessive instantaneous impact force. At the same time, regularly check the alignment between the pulse valve and the spray pipe to prevent damage caused by direct impact of the spray airflow on the edge of the filter bag.
3. Flower board: The flatness and hole accuracy of the flower board need to be strictly controlled. If the flower board deforms or the hole diameter error is too large, it will cause uneven force on the filter bag after installation, increasing the risk of bag dropping. Regularly inspect the flower board for corrosion, cracking, and other issues during use, and promptly repair or replace it.
3、 Strengthen daily maintenance and operation management
1. Regular inspection: Establish a comprehensive inspection system, focusing on checking whether the filter bag is loose, skewed, damaged, etc., and promptly deal with any problems found. Especially during the initial start-up of the equipment and after replacing the filter bag, it is necessary to increase the frequency of inspections to ensure stable installation results.
2. Control operating parameters: Keep the dust collector operating under design conditions to avoid drastic fluctuations in parameters such as air volume, temperature, and humidity. For example, sudden entry of high-temperature gas into the low-temperature filter bag area may cause the filter bag to shrink and deform; Excessive air volume will increase the tension of the filter bag, accelerate aging and detachment.
3. Standardized operating procedures: Operators need to undergo professional training and be familiar with the standardized steps for equipment start stop, dust cleaning, and other operations. When shutting down for maintenance, be careful when disassembling the filter bag to avoid violent operation that may damage the connecting components. When reinstalling, strictly follow the standard procedure.
To prevent bag dust collectors from falling off, it is necessary to comprehensively control the installation quality, accessory selection, and daily operation and maintenance. By taking the above measures, not only can the phenomenon of bag dropping be effectively reduced, but the service life of the filter bag can also be extended, ensuring the stable and efficient operation of the dust collector and providing reliable guarantee for the environmental protection standards of industrial production. Targeted optimization of anti bag measures for different working conditions involved in foreign trade business can better enhance the adaptability and competitiveness of equipment.
