How can the pleated filter bag meet the environmental protection requirements?

2022-04-02 Page view : 46 views

With the improvement of environmental protection requirements and standards, SFFILTECH said that many old bag filters in units cannot meet the new environmental protection requirements and standards, which raises a problem. How can we transform the filters to meet the national emission standards? The transformation is at hand, reduce the wind speed and increase the filtering area of the dust collector. In fact, according to the equipment of some companies, the maximum length of many cloth bags is eight meters. In this case, in the process of transformation, many old dust collector shells cannot increase the filtering area of the filter bag. There is a market demand for products, and there is a market for new wrinkled dust removal filter bags.

 

Pleated filter bag is also called star dust removal filter bag. This is a new type of dust removal filter bag that can be applied to pulse bag filter. The dust removal framework used with pleated dust removal filter bag needs special design, and other supporting components are universal. The principle of pleated filter bag is to improve the filtration efficiency by reducing the filtration wind speed under the condition of constant air volume, so as to prolong the service life of the pleated filter bag and achieve the purpose of low emission. The advantage of pleated filter bag is that it can directly replace the round filter bag without any change to the main body of the dust collector.

 

The effective inner diameter of the pleated filter bag is relatively small. Compared with the same round filter bag, the pleated filter bag presents an irregular shape and is easy to remove the ash. The pleated filter bag has shallow folds and large space in the middle, which will not cause agglomeration like the dust removal of the filter cartridge. SFFILECH said: the dust removal technology of the pleated filter bag is better, which combines the characteristics of the bag filter and the filter cartridge. Of course, this can also replace the traditional bag filter and cartridge filter, and can be applied to the transformation of the current pulse bag filter.
