Basalt filter bag

Basalt filter bag is a kind of high-performance filter material, which is widely used in the field of industrial dust removal due to its high temperature resistance, corrosion resistance and high strength.

1. Main characteristics of basalt filter bag

High temperature resistance: basalt filter bag can keep stable structure in high temperature environment, and is not easy to deform or melt. Its high temperature resistance is mainly due to the unique composition of basalt fibres, a natural mineral fibre that maintains stable performance at extreme temperatures. Some filter bags can be used for a long time at 380 ℃, the instantaneous temperature can reach 600 ℃, and even some can be used for a long time at 760 ℃.

Corrosion resistance: basalt filter bag has excellent corrosion resistance and can resist the corrosion of various acid and alkali solutions. It is applicable to acid and alkali treatment and electroplating wastewater treatment in chemical industry.

High strength: basalt fiber has high strength and low elongation, so the filter bag made of basalt fiber has good mechanical property, the breaking strength is generally above 3000N, the size is stable and not easy to be damaged.

Good air permeability: basalt filter bag fabric has high void ratio, smooth surface and good air permeability, which can ensure smooth air passing through, reduce filtration resistance and improve filtration efficiency.

2. Basalt filter bag application field

Industrial waste gas treatment: basalt filter bag is widely used in desulfurization and dedusting of coal-fired power plants, dedusting of steel plants, cement plants, metallurgy, mines, foundry enterprises and other industrial waste gas treatment fields, effectively intercepting and removing pollutants such as particulate matter, dust, oil mist and harmful gases in the air, making contributions to improving air quality and protecting ecological environment.

Chemical production: In chemical production, many process flows need to be carried out under high temperature and corrosive environment. Basalt filter bag, with its high temperature resistance and corrosion resistance, performs excellently in these environments, reducing the replacement cost and downtime of enterprises.

3. Benefits of basalt filter bags

High filtration efficiency: basalt filter bag has high dust collection efficiency, reaching more than 99.5%, especially for dust particles with diameter less than 0.5mm.

Long service life: basalt filter bag has high temperature resistance, corrosion resistance, high strength and other characteristics, so it has a long service life, reducing the cost and trouble of frequent replacement of filter bag.

Easy to remove dust: basalt filter bag has a large amount of smoke and dust, convenient operation and maintenance, easy to remove dust and improve work efficiency.
