Pleated filter bag introduction: it is also called pleated cloth bag, pleated dedusting filter bag, also called star dedusting filter bag. It is a new type of dedusting filter bag that can be applied to pulse bag filter. The dedusting framework used with pleated dedusting filter bag needs special design, while other supporting components are commonly used.

Advantages of pleated bags:

1. It can directly replace the existing filter bag of bag type dust remover, without modification of the main structure of the dust remover, and the filter area can be increased by 50-150% after replacement;

2. It can significantly reduce the pressure difference of the system, so as to improve the overall performance of the system and the life of the dedusting filter bag itself;

3. It can greatly reduce the frequency of ash removal or extend the interval of ash removal;

4. Compared with the traditional filter bag, because of the special structure of pleated filter bag, the efficiency of pulse dust removal is obviously improved;

5. The effective use area of dedusting filter bag is increased, and the rising speed of air flow between dedusting filter bags is decreased, which greatly optimizes the effect of on-line dedusting;

6. The special design of the filter bag and the dedusting framework of the pleated filter bag can greatly reduce the fatigue damage and intermittent emission caused by pulse injection;

7. There is no horizontal support ring for the dust removal framework, and the effective contact area is large, which completely avoids the direct impact on the dust removal filter bag;

8. According to the demand, the length of pleated filter bag can be shortened while the filtering area is increased, and the operation of the system can be o

9. Greatly reduce the consumption of compressed air and the load of air compressor and pulse valve;

10. The load of the fan is greatly reduced, and the energy consumption of the system is significantly reduced;   

11. The maintenance cost of the system is significantly reduced, including energy consumption, auxiliary equipment, parts and labor;

12. Any existing filter bag material suitable for the system requirements can be used;

13. The traditional filter bag can still be used as the emergency spare part of pleated filter bag, but the corresponding dedusting framework should be used;

The old bag filter in many units can not meet the new environmental protection requirements, so it must be reformed to reduce the wind speed and increase the filter area, so that the dust collector can meet the national emission standards. According to the current equipment level of our dust collector pulse system, the use length of the cloth bag is up to eight meters. In this case, in the process of transformation, the old dust collector shell cannot increase the filtering area of the filter bag. Now we recommend a new pleated filter bag. Pleated dedusting filter bag, also known as star dedusting filter bag, is a new type of dedusting filter bag that can be applied to pulse bag filter. The dedusting framework used with pleated dedusting filter bag needs special design, while other supporting components are universal. Principle of pleated filter bag. Under the condition of constant air volume, the filtering efficiency can be improved and the service life can be prolonged by reducing the filtering air speed. To achieve the goal of ultra-low emissions. Advantages of pleated filter bag: it can directly replace the existing round filter bag without any modification of the main body of the precipitator. According to the design and demand of the system, the filter area can be increased by 1.5 to 2 times, which can significantly reduce the system pressure difference and thus improve the overall performance and bag life of the system. With the increase of effective belt spacing, the rising speed of air flow between belts decreases, so as to achieve the effect of optimizing belt line. The fan load is greatly reduced, and the system energy consumption is significantly reduced. The pleated filter bag uses medium and low pressure. If the ordinary 2.5m filter bag is used, about 0.3-0.5mpa can be used. The effective inner diameter of the pleated filter bag is very small, and compared with the round bag, it is irregular shape. The pulse air flow can shake off the filter cake without completely overcoming the negative pressure to complete the ash cleaning. There is a relatively loose part in the middle of the pleated cloth bag, and the vibration amplitude is large when spraying, which is easy to clean the ash. In addition, the folds are shallow and the space in the middle is large, which will not cause the agglomeration like the ash removal of the filter cartridge. Pleated filter bag dedusting technology combines the characteristics of bag filter and cartridge deduster, which can be used to replace the traditional bag filter and cartridge deduster, and also can be used to transform the existing pulse bag filter.
