What is a fiberglass filter bag?

Fiberglass filter bags represent a cutting-edge solution in industrial filtration, leveraging the exceptional properties of fiberglass fibers. Renowned for their high tensile strength, thermal resistance, and chemical inertness, fiberglass filter bags excel in diverse applications within industrial filtration systems. These bags, integral to dust collectors and air pollution control equipment, play a pivotal role in mitigating environmental impact. The robust fiberglass filter media ensures effective particle capture, making them ideal for high-temperature environments, industrial processes, and flue gas treatment. Their versatility extends to applications in industrial dust collection, environmental protection, and gas filtration, where they demonstrate longevity and efficiency. Fiberglass filter bags, with their advanced filtration capabilities and durability, stand as a cornerstone in the quest for cleaner and healthier industrial environments.

Product description

Glass fiber filter cloth is made of the fiberglass yarn, with special treatment like graphite, silicon, ptfe dipping, against acid treatment and other chemical treatment. It is an ideal high temperature resist filter cloth the fiberglass filter bags are widely used in industrial dust clean area, bag house, air pollution and valuable dust recycling, etc.

The performance of woven glass fiber filter media the performance and service life of glass fiber filter media vary with the type of yarn, fiber diameter, twist, density and fabric structure. The influence of fabric structure on filter material performance is as follows.

① Wear resistance: Plain>twill>forged grain.

② Softness: Forged grain>twill>plain grain.

③ Void ratio: Forged grain>twill>plain grain

Two factors effect the choice of filter bags

Two factors effect the choice of filter bags: Temperature: As the main component of dust collector, it is very important whether selected filter bag adapt to the flue gas temperature . Such as, the heat resistance of filter material exceeds the flue gas temperature too much, which will cause the waste of high temperature filter material as well as big investment in equipment. If it is lower than that of flue gas, it is possible to cause the burning of bag. So how to select the filter material according to the flue gas temperature? It can be divided into the following according to the temperature: normal temperature filter material: below 130 degrees Celsius, medium temperature filter material 130~180, high temperature filter material 180~280.

Flue gas composition: It includes the content of dust, specific gravity, particle size, viscosity or not, the water content in the flue gas and other parameters. All of these decide the way of cleaning, filter bag material treatment, filtration velocity. Usually, if the dust is dense, sticky and light, we usually choose pulse bag house and pulse bag filter. In addition, the filtration velocity is control more than 1.2m /min, sometimes 1m /min. As well as, the Filter material treatment is generally membrane, water and oil repellent, anti - static, oriented anti adhesive treatment.

Dust Separation Procedure

Different dust separation procedures require different weights and air permeability values for filter media.

Rules:

- The more effective the cleaning process, the more compact and heavier the filter medium can be.

- The higher the emission control standards, the heavier the filter medium should be.

Tops: If these factors are well considered in advance, running cost like electricity for the fan or pressured-air for the cleaning pulses can be saved later on in a great amount.
