Types of high temperature dust filter bags

High-temperature filter bags are called the cardiovascular of filter bag dust removal equipment, and are usually called dust collector filter bags or filter bags. Dust collector filter bags are an important part of the entire operation of filter bags dust removal equipment. The materials and design schemes of dust removal filter bags should be continuously pursued. The actual effect of filtering, soot detachment and firmness. The types of high temperature filter bags are as follows:

1. High temperature

1. Aramid needle felt filter bag 

Aramid filter bags, also called Metas filter bags, Metas is the generic name for Noumes manufactured by DuPont in the United States and Conex manufactured by Teijin Corporation in Japan. However, it has been applied for cancellation very early, and they are now collectively referred to as aramid filter bags. Dust-containing flue gas is filtered and separated when the temperature is high around the acid leakage point. Specially made with imported heat-resistant chemical fiber, it has the characteristics of heat resistance, high toughness, strong acid and alkali corrosion, wear resistance, compressive strength, etc. After different surface organic chemistry solutions and post-combing technology, it is easy to remove dust, waterproof, oil resistant, and resistant. Compared with the glass chemical fiber filter material, Metas heat-resistant needle-punched felt has significantly enhanced abrasion resistance, flexural resistance and tensile strength due to the effects of static electricity. It bears high filter load and has low running frictional resistance. Compared with the production of chemical fiber heat-resistant filter material, it gets rid of the shortcomings of chemical fiber filter material elongation, large deformation, low temperature resistance and poor corrosion resistance. The specifications are stable, the compressive strength is good, and the price is lower than other heat-resistant synthetic fibers. Vacuum cleaners are used for asphalt mixing, shaft kiln exhaust gas from chemical plants, kiln gas from calcium carbide plant, ironmaking, forging smoke, and coking plant smoke.

2. Fiberglass filter bags

Fiberglass also call FMS ,FMS heat-resistant needle felt has the characteristics of heat resistance, high toughness, strong acid and alkali corrosion, abrasion resistance, compressive strength, etc. After different surface organic chemistry solutions and post-carding technology, it has easy dust removal, Waterproof oil, antistatic and other functions. The product has the characteristics of heat resistance, high toughness, strong acid and alkali corrosion, abrasion resistance, compressive strength, etc. After different surface organic chemistry solutions and post-combing technology, it has the functions of easy dust removal, waterproof oil, antistatic, etc. It is suitable for 150° C-400°C product series. Compared with glass fiber filter material, FMS filter material has significantly enhanced abrasion resistance, flexural resistance and tensile strength, and can bear high filter load. The filter speed can reach about 1.6 m/min or higher, and the running friction resistance Low.

3. Fiberglass needle felt filter  bag

Glass fiber needled felt filter bags have the advantages of glass fiber textiles such as heat resistance, corrosion resistance, stable specifications, minimal elongation and shrinkage, and high compressive strength. High temperature filter bags and felt layer chemical fiber single chemical fiber, three-dimensional microporous plate Structure, high porosity, low friction resistance for steam filtration, high-temperature smoke filtering glass fiber needle felt for various industrial production rice kilns, such as chemical plants, steel, smelters, carbon black, power generation, concrete, etc., can be divided into chopped chemical fibers Needle felt and continuous original needle felt. The short-cut chemical fiber needle felt cuts the thick glass fiber into 60 mm, and lays it on the substrate on the conveyor belt, and then uses a needle with a hook to punch the short-cut chemical fiber into the substrate, and the crochet needle rises. Some chemical fibers produce three-dimensional structures.


4. P84 needle felt filter  bag

P84 heat-resistant needle-punched felt is an excellent heat-resistant variety produced by our company using INSPECFIBERS polyimide fiber produced by Austrian LENZING company and under the specific guidance of foreign technology companies. It is the first manufacturer in China to mass-produce this filter material. enterprise. The characteristic of P84 is that the particle size of the chemical fiber itself is obvious. The cross section of the curved chemical fiber greatly increases the area of the chemical fiber and shows a lot of pores. The actual effect of surface filtration is better than that of depth 1 filtration. The smoke and dust only stay on the surface of the felt and cannot pass through the felt. The pressure of backwashing operation is low, the efficiency of the cake bomb shedding is obviously improved, the efficiency of collecting fine micronized powder is high, and the pressure difference of safe operation is small. Suitable for coal-fired steam boilers, liquid bed heating furnaces, garbage incineration, asphalt plants, chemical plants, waste incinerators, etc.
