How to calculate the filter area of a bag filter

Do you know how to calculate the filter area of the bag filter? If you want to choose a high-efficiency dust removal device, you must consider the relevant parameters of the bag filter, for example, what is the filter area of the filter? Choose the type of filter, then how to calculate the filter area filter? Hebei Qingrun Environmental Protection Equipment Co., Ltd. tells you how to calculate the filter area of the bag filter is:
1, the total filter area According to the total amount of dust through the dust collector and the predetermined rate of filtration, according to the following formula to calculate the total filter area: After the total filter area, you can determine the overall size and size of the bag filter.
2. The area of a single circular dust bag is during the processing of the dust bag. Because the dust bag should be fixed on the flower board or the short pipe, some of them should be hung up and fixed on the bag cap. Therefore, the two ends of the dust bag need double sewing. Even multi-layer sewing: this part of the double-seam sewing has no filtering effect due to the increase of resistance, while some dust bags also need to be fixed in the middle of the ring, this part also has no filtering effect. In the large and medium-sized counter-blowing dust collectors, the dust removal bag is 10 meters long and 0.292 meters in diameter, and its nominal filtration area is 0.0292*10=925m; if the area with no filtering effect is deducted by 0.75m, its net filtration area is from 8.25-0.75= 7.5m. It can be seen that the unused filter area accounts for 5% to 10% of the bag area. Therefore, the size of the net filter area should be specified in the specifications of the large and medium dust collectors. However, in the existing bag filter samples, most of the filtering area refers to the nominal filtering area, and care should be taken in the design and selection.
