    Folding dust removal skeleton

  • 除尘布袋,能直接替代除尘器现有圆(椭圆)滤袋和龙骨而无需对主体设备做结构性改造按系统设计和需要,一般可增加过滤面积50-150%。 The pleated dust bag can directly replace the existing round (oval) filter bag and keel of the dust collector without structural modification of the main equipment. According to the system design and needs, the filtering area can generally be increased by 50-150%. Significantly reduce the system pressure difference and thus improve the overall system performance and bag life. Significantly reduce the cleaning frequency or extend the cleaning interval. Compared with ordinary cloth bags, the pulse cleaning efficiency (same filter material) is significantly improved due to its special structure, the effective bag spacing is increased, and the rising speed of air flow between bags is greatly optimized. Online cleaning effect. 褶皱除尘布袋/褶皱除尘骨架的特殊设计大大降低因脉冲喷吹引起的疲劳损伤和间歇性排放。 Botou Wanheng Dedusting Equipment Co., Ltd. 's special design of pleated bag / pleated dedusting frame greatly reduces fatigue damage and intermittent emissions caused by pulse spraying. The keel has no lateral support ring and has a large effective contact area, which completely avoids direct impact on the cloth bag. 布袋除尘器 According to requirements, while increasing the filtering area, shortening the length of the bag to optimize the system operation, greatly reducing the amount of compressed air and the load of the air compressor and pulse valve, the load of the fan is greatly reduced, and the energy consumption of the system is significantly reduced. Convex pleated filter bag and pleated bag filter . Under the same conditions, the filtering area can reach 160% to 200% of the cylindrical filter bag, the equipment running resistance can be reduced to 600 to 800Pa, and the discharge concentration under the working conditions can reach 10mg / m³ or less.

     Common problems of pleated filter bags: Pleated filter bags can replace traditional round cloth bags, with obvious dust removal effect, and greatly increase the filtering area and reduce the amount of back blowing. It is a revolutionary new type of cloth bags: Frequently Asked Questions 1. What is the price of a pleated filter bag and its supporting cage?  Due to the increase in the filtering area and the use of cage bones, the price will be appropriately raised.  The comprehensive cost of manufacturing, transportation, installation, maintenance and energy consumption of the dust collector can be considered comprehensively.  2. Will the gap between filter bags be increased compared to normal filter bags?  For the transformation of the traditional bag filter, the filter bag interval can be the same as that of the ordinary round bag.  For the newly designed dust collector, in principle, the larger the interval is, the better, but the larger the dust collector volume is, the larger the cost will be. Therefore, the general design will take an optimized distance).  3. What are the requirements for injection pressure?  Is it easy to remove dust?  The injection pressure is related to the air-to-cloth ratio. The pleated filter bag is easy to use at low and medium pressure. For example, a 2.5-meter filter bag with an ordinary valve can be used at about 0.3-0.5MPa. The high-pressure injection design of an ordinary round bag is generally high-pressure 0.5-0.7MPa It is not a problem to use it in the wave filter bag, but it is not necessary.  The effective inner diameter of the pleated filter bag is very small, and compared with the round bag, it has an irregular shape. The pulse air flow can shake off the filter cake without completely overcoming negative pressure, and the dust is cleaned. The pleated bag has a relatively loose part in the middle. The amplitude of vibration during blowing is large, and it is easy to remove dust.  In addition, the folds are shallow and the space in the middle is relatively large, which will not cause agglomeration like the dust removal of the filter cartridge.  4. What is the difference between air cloth ratio?  In principle, the air-to-cloth ratio of the new dust collector can be designed as an ordinary round bag, that is, 1.0-1.2m / min. 5. Can the energy consumption be saved, and through what aspects?  Under the same circumstances, the dust removal effect of the pleated filter bag will be better than that of ordinary round bags. Under the same air-to-cloth ratio, the compressed air consumption will be reduced. The blowing frequency will be reduced (the blowing interval will be extended), and the life of the blowing valve will also be Extend. If the same number of round bags are used to handle the same air volume, the energy consumption of the fan will be reduced by about 40-50% (this is related to the design air-to-cloth ratio) --- this is the case where the wave filter bag is used instead of the round bag (That is, the reconstruction of the existing dust collector). 6. Is there any change in the housing of the dust collector?  Are there savings in material and volume?  If the newly designed dust collector uses the same air-to-cloth ratio design as the round bag, the cross-sectional area of the box can be reduced by 85%, so the volume can be reduced by 85%, so the material can be saved equally. Both the number of injection pipes and pulse valves The corresponding reduction is recommended, and the air-to-cloth ratio is slightly lower during the design. For example, the filtration area should be increased by 50% instead of 80%, so that customers will experience a longer bag life and better operating results.  7. How many years has the pleated filter bag been used? Are there any successful cases in China?  The pleated filter bag technology has been used abroad for nearly 20 years, and many projects have adopted this technology.  There are also three years of successful use cases in China. For example, Guodian Chifeng Chemical Co., Ltd. has recently replaced the original filter bag with a pleated filter bag, which has passed the acceptance and achieved very good economic benefits.
