P84 filter bag is a flame-retardant, temperature-resistant and stable fiber filter material. Under the condition of 240 ℃ temperature, the machine of P84 polyimide fiber filter material will not change, and the highest temperature can reach 260 ℃. P84 fiber filter material has no melting point temperature and is natural golden yellow. P84 polyimide fiber filter material is not a hygroscopic fiber filter material (under the condition of 65% relative humidity, the water absorption is about 3%). In addition, because P84 fiber has a special (leaf-shaped) cross-sectional structure, it has a large filtering surface area and excellent filtering performance, so P84 fiber is often implanted on the surface of the filter material (the side of the dust facing side to improve the filtering performance of the filter material. ).

1. Working temperature 160 ℃, short-time working temperature 190 ℃. 2. It is applicable when the oxygen content is 15% or less.  3. Sulfur containing oxides in fuel or flue gas are now fibers with strong acid-base corrosion resistance and chemical resistance.  4. Where the flue contains moisture. 

1. Excellent high temperature resistance: it can work continuously at 204 ℃, and the instantaneous working temperature can reach 240 ℃.  2. High dimensional stability: only 1% expansion rate at 230 ℃, with high temperature stability.  3. Fire resistance and flame retardancy: decomposition and carbonization begin at 400 ℃, the limit oxygen index (LOI) is 30, and it does not spontaneously ignite or support combustion.  4. Good chemical corrosion resistance: acid and alkali resistance, not easy to corrosion.

PTFE (polytetrafluoretyhylene) also known as Teflon that always be treated as the KING of the plastics due to the properties of high temperature resistance (maximum can stand 280 degree C), corrosion resistance (suitable for PH1~14), longer service life, no-sticky, etc. So, the PTFE fiber is an innate excellent raw material for the industrial filter cloths production.

FMS filter bag is a highly efficient high temperature resistant, corrosion resistant, acid and alkali resistant, wear resistant composite product. Flumes is a new high-temperature filter material developed for dry dust removal of blast furnace gas.

Bags and cages are the heart of any fabric filter system.  Proper material selection, based on process conditions and emission guarantees, bag to cage fit and bag to tubesheet fit is essential for a system to operate properly.   If you are having short bag life, high pressure drop or not meeting emission limits then our technical experts can recommend the appropriate bag material.

Filter sleeves are composed by industrial filter material bag body, snap ring, clamp, chain hoist, etc. The rest of the filter sock dust collector and its accessories are the venturi tube, frame, mouth of elastic ring, etc.

SCR technology is  a recation at use of  the denitration catalyst at a certain temperature(270-400 degree),that NOX in the flue gas mixed with  ammonia gas from the reducing agent  supply  the system after the occurence of the selective catalytic reduction reaction of nitrogen and water ,thereby  reducing NOX emissions , and reducing smoke  pollution to the environment.

Under the condition of normal flue gas temperature, bag filter for dust filter bag and heat-resistant requirements under 150 ºC, and suitable for dust is not completely dry, and the situation of a certain humidity. It is necessary to adopt waterproof and anti-oil treatment, Avoid the hydrolysis of the filter cloth, and improve the dust removal of the filter cloth.
