PTEE bag+stainless steel frame

PTEE bag with stainless steel frame is a stable combination solution in the industrial dust removal industry, suitable for various complex and harsh working environments.

PTEE bag

Material and Structure: The material of PTEE bag is polytetrafluoroethylene, also known as Teflon. It has high chemical stability and is known as the "plastic winner". PTEE bags are usually made using needle punched felt technology, and the surface can also be covered with PTFE microporous film. The microporous pore size of the film is between 0.1-3.5 μ m, and the porosity reaches 75-90%.

Performance characteristics: It has excellent (based on actual reports) performance and can operate continuously at a temperature of 240 ℃, with an instantaneous temperature of up to 260 ℃. At the same time, it can withstand acid and alkali erosion within the entire pH range, has strong chemical stability, and also has good self lubrication, non hygroscopicity, and UV resistance. Its filtration efficiency is good, especially the membrane filter bag, with a filtration accuracy of over 89.990%, and its dust cleaning performance is good, which can effectively reduce the pressure drop of the equipment.

Application industry: mainly used for flue gas treatment in coal-fired boilers, waste incineration, carbon black production, titanium dioxide production and other processes, and also widely used in metal smelting, chemical production and other industries.

Material and Structure: Stainless steel skeletons are generally made of 304, 316, or 316L stainless steel materials, and are evenly distributed and welded with longitudinal bars and support rings through meticulous welding processes. Its structural forms include integral, multi section, Venturi tube, etc., which can be selected according to actual needs.

Performance characteristics: It has the ability to corrode (based on actual reports) and can work stably in corrosive environments such as acid, alkali, salt, and (based on actual reports) solvents. (Based on actual reports) Good performance, stable operation within the range of -40 ℃ to 400 ℃, and not easily deformed at high temperatures. Its surface is smooth and free of burrs. After polishing or electrolytic treatment, it can reduce the wear on the filter bag and also facilitate dust cleaning. In addition, the stainless steel skeleton also has the characteristics of being relatively lightweight, which can provide stable support for the filter bag.

Specification and size: The diameter is usually between 110mm-160mm, and the length can be customized, up to 8 meters long. There are multiple options for the number of longitudinal bars, such as 8, 10, 12, etc., to meet the support needs of different specifications of filter bags.

Combination advantage

The combination of PTEE bag and stainless steel frame fully utilizes the advantages of both, and can adapt to various harsh industrial environments such as high temperature and high corrosion, providing excellent protection for flue gas purification systems. It has excellent dust removal effect, high efficiency, prolongs the service life of equipment, reduces maintenance costs, and is a good choice for dust control in harsh industrial environments.
