Determination of the filtering area of the bag filter


The determination of the filter area of the bag filter, Determination of the filter area of the bag filter When you choose a dust collector, you want to choose a high-efficiency dust removal equipment, but when you choose, you must consider the parameters of the dust collector, such as what is the filter area of the dust collector? After considering the selection of the dust collector, how should the filter area of the dust collector be calculated? The determination of the filter area of the bag filter is as follows:

1. Total filtering area According to the total air volume passing through the dust collector and the predetermined filtering speed, the total filtering area is calculated according to the following formula: After the total filtering area is obtained, the overall size and size of the bag filter can be determined.


2. The area of a single circular dust bag. During the dust bag processing, the dust bag must be fixed to the flower plate or short tube, and some must be hung and fixed to the bag cap. Even multi-layer sewing: This part of double-layer sewing has no filtering effect due to increased resistance. At the same time, some dust-removing cloth bags have a fixing ring in the middle, and this part has no filtering effect. In large and medium-sized reverse blow dust collectors, the dust-removing cloth bag is 10 meters long and 0.292 meters in diameter, and its nominal filtering area is 0.0292 × 10 = 925m; if the area without filtering effect is 0.75m, its net filtering area is from 8.25-0.75 = 7.5m. It can be seen that the useless filter area of the bag accounts for 5% to 10% of the area of the bag, so the size of the net filter area should be indicated in the specifications of the large and medium dust collectors. However, in the existing dust collector samples, most of the filtering area refers to the nominal filtering area, which should be paid attention to in the design and selection.

3. The number of dust-removing cloth bags After calculating the total filtering area and the area of a single dust-removing cloth bag, the number of dust-removing cloth bags can be calculated. If the number of dust removal bags in each bag room is determined, the total number of dust collector rooms can also be calculated from this. Although the number of rooms is determined as required in the design or selection of dust removal, considering the site layout and maintenance alone, the number of rooms of the dust collector with more than six rooms is often set to double rows.
