The dust collector filter bag is the main and most important component of the bag filter. When dust gas is filtered through a filter bag, the fibers of the bag sieve and retain the dust, making the dust gas kept on the surface of the bag to separate the dust from the gas and purify the gas. Dust collector filter bags are divided into different materials: PTFE bag, fiberglass filter bag, P84 bag, PPS bag, aramid bag, homopolymer acrylic bag, polyester bag, etc. These dust collector filter bags are used in various industries due to their different material properties. One of them, the PTFE bag, has its particular advantages in ultra-clean emission applications. Continue reading this article to find out more.

During the operation of the bag filter, due to unreasonable design of the dust removal system, improper installation, unreasonable setting of operating parameters, and filter material material, etc., the filter bag may be damaged and fail, thereby affecting the service life of the filter bag and the operation status of the filter. and particulate emissions. The reasons for the damage of filter bags during operation include chemical damage (acid-base corrosion, oxidation and hydrolysis, etc.), air scouring (inside and outside the bag) and mechanical friction. According to the failure detection and analysis results of old bags of Anhui Confair Testing Technology Co., Ltd. (CNAS, CMA) in 2021, as shown in Figure below, except for the phenomenon of condensation and sticking bags caused by working conditions, the number of damaged filter bags is the largest. The main reason for the damage of the filter bag is the friction between the filter bag and the filter bag. The filter bag damage caused by the friction between the bags accounts for the highest proportion, accounting for 70% of the broken bags; therefore, improving the wear resistance of the filter bags by effective methods will effectively delay or avoid the damage and failure caused by friction, and prolong the filtering time. service life of the bag. In order to solve customers' pain points and fundamentally improve the wear resistance of filter media, Yuanchen Technology has the following technical advantages: 1. Double-layer bag bottom reinforcement technology; 2. AR-21 gel silicon-based high wear-resistant filter material. Yuanchen Technology adopts modified fiber technology, premixed gradient technology and sol-gel-supercritical drying technology, etc. As shown in the figure below, it has developed AR-21 gel silicon-based high wear-resistant filter material, which can adapt to different working conditions The use requirements of the filter material have fundamentally improved the wear resistance of the filter material. The technical innovations of AR-21 gel silicon-based high wear-resistant filter material are: 1. Modified PPS fiber: By modifying the fiber to improve its tensile properties, the filter material has excellent breaking strength and breaking elongation; 2. "Pre-mixed gradient" technology, designed a pre-mixed-fineness/density graded combination of asymmetric gradient structure filter material, formed by ultra-fine fibers to form a dense layer and the bottom layer to form a density gradient structure to achieve high-precision filtration, in non-film-coated Under the circumstance, it can meet the ultra-clean emission of dust particles (< 5mg/Nm3), and the operating resistance of the filter bag is lower than that of the film-coated filter material, which truly realizes "high efficiency and low resistance"; 3. Super wear-resistant technology, using sol-gel method, nano-scale silicon-based particles are aggregated with each other to form a nano-porous network structure, and the ...

The size of the flower plate is the key to determining the structure and size of the pulse bag filter. The round holes on the flower plate are used to fix the filter bag. If the center distance of the holes is too small, the cross-sectional wind speed in the filter will be too high, and the resistance will increase. It is difficult for dust to settle when cleaning dust; it may also cause friction between dust filter bags and shorten the service life of diffuser bags. On the contrary, if the center distance is too large, it will increase the volume of the dust collector and cost more steel. Therefore, it is necessary to reasonably determine the size of the center distance of the filter bag. In addition to bearing the weight of the filter bag and the bag cage, the flower plate also bears the gas pressure in the dust collector, so it must have sufficient rigidity. If there is a slight modification, it may affect the sealing effect between the filter bag and the hole of the flower plate. The thickness of the steel plate of the flower plate is generally 4~6mm, which mainly depends on the number of filter bags of the dust collector suspended in the filter room. In order to increase the rigidity of the flower plate, reinforcing ribs should be added on the flower plate. The appearance of the flower plate should be smooth and clean, and there should be no warping or uneven unevenness. The deviation of the flatness should not be greater than 2/1000 of the length of the flower plate. Holes should be punched or plasma cut, and gas cutting is not allowed. The tolerance of the hole diameter d of the filter bag flower plate fixed with the elastic expansion ring is .
