Dust removal bag is a key part of the operation of the bag type dust collector. The fabric and design of the dust removal bag should strive for efficient filtration, easy dust peeling and durability. Generally, the cylindrical dust bag is suspended vertically in the dust collector.
Selection criteria of high temperature resistant dust bag filter bag:
1. The function of high temperature resistant dust-removing cloth filter bag should meet the general conditions and special requirements of production conditions and dust-removing technology. With moderate temperature resistance, moderate acid and alkali resistance and very good abrasion resistance. The space between the hole and the hole of the dust collector is too close, and the bottom of the cloth bag rubs against each other and wears. The bottom of the internal distribution bag breaks during a few months of operation. It will also cause the airflow in the dust collector box to rise too fast, resulting in the increase of smoke emissions. Part of the filtering load of the dust filter plate filter material is too high and the dust cleaning strength is insufficient. The dust removal frame is called the rib of the dust removal filter bag. The quality of the dust removal frame directly affects the operating status and service life of the filter bag. The dust removal frame is welded and formed by special equipment at one time. The post-processing of the dust removal frame is generally divided into galvanizing and plastic spraying. , Silicone treatment, and our company's dust removal framework with silicone treatment has better thermal stability and resistance to radiation and weathering. Silicone is not only resistant to high temperature dust removal cloth bags, but also resistant to low temperature whether it is chemical or physical The mechanical function and the change with temperature are very small. In addition to excellent heat resistance, silicone also has excellent water repellency.
Brief introduction of high temperature dust bag
1. Metas Needle Felt Dust Cloth Bag Metas is the general name of Nomex produced by DuPont of the United States and Conex produced by Teijin of Japan. Dust-containing flue gas can only be separated under acidic conditions, that is, at high temperatures. Refined from imported high temperature resistant fibers, it has the characteristics of high temperature resistance, high strength, resistance to acid and alkali corrosion, abrasion resistance, folding resistance, etc., through different appearance chemical treatment and post-cleaning technology, it also has easy cleaning, water and oil resistance. , Anti-static and other functions, compared with high-temperature needle felt and glass fiber filter material, Metas has significantly improved abrasion resistance, bending resistance and peel strength, can bear high filtration load, low running resistance. Compared with the chemical fiber high temperature resistant filter material, it overcomes the shortcomings of chemical fiber filter material such as elongation, large deformation, low temperature resistance and poor corrosion resistance. The scale is stable, the strength is good, and the price is lower than other high temperature resistant chemical fibers. It is suitable for dust collection in asphalt mixing, exhaust gas from cement kiln, kiln gas from calcium carbide plant, steelmaking, foundry flue gas, coking flue gas, etc.
2, Flumes dust-removing cloth bags Flumes (FMS) high temperature needle felt has the characteristics of high temperature resistance, high strength, resistance to acid and alkali corrosion, abrasion resistance, bending resistance, etc., through different appearance chemical treatment and post-cleaning technology, It has the functions of easy cleaning, water repellent, oil proof, anti-static and so on. The product has the characteristics of high temperature resistance, high strength, resistance to acid and alkali corrosion, abrasion resistance, and resistance to folding. Through different external chemical treatments and post-cleaning technologies, it also has functions such as easy ash removal, water and oil resistance, and antistatic. 200 ° C-300 ° C series products. Compared with glass fiber filter materials, FMS filter materials have significantly improved abrasion resistance, bending resistance and peel strength, can bear high filtration load, filtration speed can reach 1.5 m / min or more, and low running resistance. . Compared with the chemical fiber high temperature resistant filter material, it overcomes the shortcomings of chemical fiber filter material such as elongation, large deformation, low temperature resistance and poor corrosion resistance. The scale is stable, the strength is better, and the price is lower than other high temperature resistant chemical fibers. Widely used in iron and steel, non-ferrous smelting, chemical, carbon black, building materials, power and other departments.
3.Glass fiber needle punched felt dust removal bagGlass fiber needle punched felt dust removal bag has the advantages of glass fiber fabric high temperature resistance, corrosion resistance, stable size, minimal elongation and shrinkage, high strength, and felt fiber contract fiber, three-dimensional Microporous structure, high porosity, and low resistance to gas filtration. It is a high-speed and efficient high-temperature filtration data. Can be widely used in chemical, steel, smelting, carbon black, power generation, cement and other industrial kiln high temperature flue gas filtration fiberglass felt felt needle felt or chopped fiber needle felt felt and continuous filament needle felt felt. Chopped fiber needle felt is chopped glass fiber roving into 50mm, randomly laid on a substrate placed on a conveyor belt in advance, and then needled with a barbed needle. The needle pierces the chopped fiber into the substrate. And the crochet brings up some fibers to form a three-dimensional structure. The substrate used may be a thin fabric of glass fiber or other fibers. This needle felt has a fluffy feel. Its primary uses include use as heat insulation and sound insulation data, heat lining data, and filtration data. It can also be used in FRP production, but the produced FRP has low strength and limited application range. Another type of continuous filament needle felt is a felt that randomly throws continuous glass filaments onto a continuous mesh belt with a spinning device and is needle-punched by a needle plate to form a three-dimensional structure of fibers. This product uses high-temperature and high-pressure cleaning method to make the filter fabric tensile strength, soft appearance, water-increasing is highly bulky, wear-resistant and tear-resistant function is improved by 1.5-3 times than ordinary filter material, acid resistance is good. The temperature is up to 280-295 ° C, the dust removal efficiency is high, the application cycle is long, and it is widely used in cement, steelmaking, coking and other occupations.
4, PPS acid and alkali resistant needle felt felt dust bag, PPS dust filter bag is a filter made by our company using polyphenylene sulfide (PPS) fibers produced in the United States, Japan and other countries, according to the production process of other high temperature resistant filter felts. Data is one of the first types of high-temperature filtering data. PPS needling filter media has outstanding functions in the following applications. PPS is also called polyphenylene sulfide fiber.
