Analysis of Advantages and Disadvantages of Dust Bags Used in Bag Filters

For bag filters, the dust bag is a key part of the operation of the bag filter. Usually the cylindrical filter bag is suspended vertically in the dust collector. So, what are the advantages and disadvantages of the dust bag? Let the dust collector manufacturers tell you! For the bag filter, the dust bag is like its heart. The efficiency of the dust collector is good, and the dust bag is the decisive factor. Usually, such a dust bag is called a dust bag or a dust filter bag, and the dust bag is a key part in the operation of the bag filter. Usually, the cylindrical filter bag is vertically suspended in the dust remover. So, what are the advantages and disadvantages of the dust bag? Let the dust collector manufacturers tell you!
First, the advantages of dust bag:
1. High dust removal efficiency, it can capture dust of 0.3nm or more, and purify dusty gas to 15mg/m3 or less.
2, can capture dust that is difficult to recycle by electric dust removal; and can collect compounds such as nitrates and sulfides at a certain level.
3, good adaptability to load changes, especially suitable for collecting fine and boring dust, the collected dry dust is easy to handle and recycle applications.
4. The bag filter collects dusty gas containing explosion risk or sparks with high safety.
Second, the defects of the dust bag:
1. For different types of gas, the corresponding type of cloth bag should be selected; and the demand is often changed to the cloth bag, and the bag cost is large.
2. When collecting dusty gas with high humidity, moisturizing measures should be taken to avoid the formation of “paste bag” due to condensation, so the bag dust removal gas has certain requirements for the humidity of the gas.
3, the resistance is large, the ordinary pressure loss is 1000 ~ 1500Pa.
The utilization rate of domestic dust-removing cloth bags has improved from time to time, and the service life has reached more than four or five years. In addition, the development of some advanced filtration materials such as PTEF membranes and composite filter materials has been newly broken.
