Generally speaking, manual cleaning is generally not recommended for dust bags, as this can easily cause the bags to tear and quickly damage. If your dust bag is clogged and pulse cleaning is not possible, it is best to replace the dust bag.
Fixed: Fine-tune dust collector pulse control system.
The pressure drop should be stable during normal operation of the dust collector, and if it is unstable, you need to reduce (or increase) the frequency of cleaning. Or contact the manufacturer to fine-tune the collector's cleaning system by adjusting the pulse controller to achieve the desired pressure drop.
Another option is to use a constant resistance method so that cleaning is only done when the pressure drop reaches the set resistance.
When a dust collector handles abrasive dust, just as improper cleaning methods can cause the bag to tear, abrasive dust can cause this. While some dust will wear out more naturally, the design of the dust collector itself can also cause increased friction between the dust and the bag. Improper inlet design, excessively high air-to-cloth ratios, and excessively high filtration rates can lead to dust contact with the filter bag and faster wear.
Fixed: Dust bag with abrasion-resistant design.
In addition to designing the dust collector to reduce the upward velocity between the filter bag and the dust, you can also use wear plates at the inlet of the dust collector.
The dust bag is too loose with the skeleton, which will also cause the bag to be damaged in advance.
In order to maximize the service life of the filter bag, the size of the dust removal bag and the dust removal skeleton should be fitted. In addition, the vertical reinforcement of the dust removal skeleton should not be too few, and it is very important to ensure the verticality of the skeleton.
Improper installation of the dust bag can also lead to poor performance of the dust collector's cleaning process, which can increase the damage caused by excessive cleaning of the bag if the loss is compensated for by cleaning the dust more frequently.
Fixed: Dust bag fits snugly to dust skeleton and uses skeleton with more vertical bars.
Proper installation of the dust bag, using a skeleton with more vertical bars can provide better support, which makes it easier to clean the ash and reduce the wear and tear of the dust bag.
