Fiberglass needle punched felt dust bag

Fiberglass needle punched felt dust bag is a new type of high-temperature filtration material with reasonable structure and excellent performance. It is made of fiberglass as raw material and needle punched into felt. Needle punched felt has a three-dimensional microporous structure, high porosity, low resistance, and dust removal efficiency that is about twice that of ordinary fabric filter materials.

This filter material has been widely used in industries such as carbon black, chemical, steel, metallurgy, and coal-fired boilers, especially in the flue gas filtration of refractory materials and cement industry. Fiberglass needle punched felt is suitable for use in bag filters for pulse dust cleaning and high-speed reverse blowing. It has been tested for a long time under high temperature and corrosive media, and has excellent performance in controlling dust pollution and recovering valuable fine particles.

Main uses of fiberglass needle punched felt dust bag

Fiberglass needle punched felt dust bag can be used for sound insulation, sound absorption, shock absorption, flame retardancy, etc. in the automotive industry, mainly for filtration in industry; Fiberglass needle punched felt is widely used for flue gas purification and dust recovery in industries such as carbon black, steel, non-ferrous metals, chemical, and incineration.

Fiberglass dust bag is a high-performance filtering material with high porosity, low gas filtration resistance, high filtration wind speed, dust removal, and characteristics such as bending resistance and stable size. Produce according to different flower board diameters and diameters.

Usage condition: The filtration wind speed should be less than 1.0m/min. The working temperature of the glass fiber needle punched felt dust collector bag should be less than 260 ℃. The alkali free glass fiber expanded filter cloth/bag is used. The alkali free glass fiber expanded filter material is produced using Nanjing Fiberglass Institute technology and German expansion equipment to produce fully expanded or two-thirds expanded filter cloth (bag).

The organization has double satin weave, diagonal weave, etc. The product specifications of medium and alkali free glass fiber expanded filter cloth (bag) are Φ 120-300mm, which has the energy of ordinary glass fiber filter materials. At the same time, after high-temperature hot washing, the fabric structure is strengthened, increased, the filtration wind speed is increased, and the service life is improved.

Main application: Medium and alkali free expanded glass fiber filter cloth (bag) is widely used for dust removal and gas filtration in industries such as steel, power, metallurgy, chemical, environmental protection, and cement.

The usage conditions of fiberglass needle punched felt: long-term use at 200 ℃ -280 ℃, optimal use temperature at 90 ℃ -220 ℃, and the working temperature in multiple FCA regions should be less than 180 ℃; The filtering wind speed should be less than 0.8m/min. Choose the appropriate material for the dust bag according to different operating conditions.
