In the application of industrial filter cloth industry, made of bags, such as dust bags, filter bags, are very common processing applications!
Here's a look:
In the field of bag-type dedusting, the dust bag is usually compared with the heart of a bag-type deduster, and what type of dust-containing flue gas the bag-type deduster can handle depends mainly on the conditions of the chemical fiber used to manufacture the dedusting bag. Therefore, we must understand the dust filter bag performance testing methods, in order to choose the most suitable dust bag. For the dust bag, the need to test and test the following:
1. Appearance inspection: punctures, defects, dark spots, jumpers, broken lines, joints and so on.
2. Physical properties: such as dust bag per unit area of quality, thickness, width, woven fabric, fabric density, bulk density of non-woven fabrics, porosity and so on.
3. Mechanical properties: such as dust bag breaking strength, elongation at break, the bag of latitude and longitude load elongation, filter burst strength and so on.
4. Dust characteristics: such as drag coefficient, static dust removal efficiency, dynamic dust removal efficiency, filter dynamic resistance, regeneration resistance coefficient and dust stripping rate.
5. Special features: such as temperature resistance, corrosion resistance, electrostatic properties, hydrophobicity and so on.
General flue gas temperature conditions, only the bag can be resistant to temperatures below 150 ℃, these occasions, polyester, polypropylene, acrylic, nylon and other chemical fibers can basically be competent. For flue gas temperature is relatively high occasions, you need to select the high temperature filter, such as glass fiber dust bag, dust Fumisi bag, the United States Tass dust bag, PPS dust filter bag, etc.
