How to choose filter materials for pulse dust collector

1. Understand the nature of dust
When selecting a dust filter bag, you need to understand the properties of the dust, including its particle size, shape, specific gravity, friction, etc. These properties determine the movement trajectory and attachment method of dust in the dust collector, thereby affecting the service life and dust removal efficiency of the dust removal filter bag.

2. Consider the characteristics of the filter material
The material of the dust filter bag directly affects the dust removal effect and life of the dust collector. Therefore, when choosing a dust filter bag, you need to understand the characteristics of different filter materials, including the material’s air permeability, temperature resistance, corrosion resistance, etc. According to actual needs, choosing filter materials with excellent performance can improve the dust removal efficiency of the dust collector and extend the service life of the equipment.

3. Determine the filtration wind speed
Filtration wind speed is one of the important factors in selecting dust removal filter bags. If the filtration wind speed is too high, the resistance of the filter bag will increase and the service life of the filter bag will be shortened; if the filtration wind speed is too low, the equipment’s floor space and investment cost will increase.

4. Choose the appropriate skeleton material
The frame of the dust filter bag is an important structure that supports the filter material and plays an important role in ensuring the shape and stability of the filter bag. When selecting skeleton materials, the strength, stiffness, corrosion resistance, etc. of the material need to be considered. According to actual needs, selecting skeleton materials with excellent performance can improve the stability and service life of the dust collector.

5. Choose according to actual needs
When selecting dust removal filter bags, you need to choose according to actual needs. For example, for high-temperature flue gas, you can choose high-temperature resistant filter materials; for flue gases containing corrosive gases, you can choose corrosion-resistant filter materials; for fine-particle dust, you can choose microporous filter materials, etc.
