Metal Fiber Filter Bag for High Temperature Flue Gas and Dust Removal

1. The characteristics of metal fiber high temperature dust collector bags

The metal fiber high temperature dust collector bag is made of micron-sized metal fiber sintered filter material as raw material, and is welded. The metal fiber sintered felt filter medium is composed of a three-layer composite of metal plate mesh, coarse metal fiber and fine metal fiber. Vacuum sintered into a whole to form a three-dimensional network structure.

High temperature dust collector bags have the characteristics of high porosity, large specific surface area, uniform pore size distribution, high dirt holding capacity, and high filtration accuracy. In addition, felt dust collector bags has high temperature resistance, corrosion resistance, high efficiency, low emission concentration, low operating resistance, long life, renewable, energy saving and other advantages, with excellent filtering performance, which is ideal high-temperature flue gas dust removal filter material, and has been widely used in industrial smoke In the field of gas dust removal, especially in high temperature, strong corrosion and harsh working conditions such as chemical industry, metallurgy, building materials, electric power, petroleum, and new energy.

2. Material and scope of application of metal fiber high temperature dust collector bags

When the operating temperature is less than 400℃, 304 and 316L materials can be selected, 304 material has good temperature resistance, 316L material has better temperature resistance and better corrosion resistance;

When the operating temperature is 400-600℃, 310S and 314 materials can be selected, which have the ability to resist high temperature oxidation;

When the high temperature is greater than 600°C, iron-chromium-aluminum materials can be selected; other materials such as Hastelloy and nickel are available as required.

Technical advantages:

• High temperature resistance, corrosion resistance, high strength, wear resistance, no perforation, no break;

• High filtration precision, high dust removal and interception efficiency, can meet the ultra-low emission requirements, and the emission concentration of particulate matter <5mg/Nm³;

• Good air permeability, low resistance, low operating energy consumption, high wind speed;

• Easy to clean dust, online back-blowing and offline cleaning, long service life, good filter bag regeneration performance;

• It can be recycled and processed without causing secondary pollution to the environment;

• Good conductivity, to avoid accidents caused by static electricity, flameproof and explosion-proof;

• Long service life, the product life can be as long as 3 to 5 years, which is 4 to 6 times the service life of cloth bags.
