Calculation of the relationship between the design of dust catcher and the quantity of dust bag First, the air volume of dust bag handling is the volume of purified gas in the unit time. The unit is cubic meter per hour (m3/h) or cubic meter per hour (Nm3/h). It is one of the most important factors in the design of bag filter. When the Bag Type Dust Collector is designed or selected according to the air volume, the dust collector can not normally run under the condition of the prescribed air volume. Otherwise, the filter bag is easy to block, the life span is shortened, the pressure loss is greatly increased, the dust removal efficiency is also reduced; but the equipment investment and the area can not be increased if the air volume is too large. Reasonable selection of air volume is usually based on technological conditions and experience. Second: calculate the total filtration area: according to the total volume of the dust collector and the fixed filtration rate, the total filtration area is calculated by pressing the formula. After determining the total filter area, the overall size and size of the bag filter can be determined. Third: according to the area of a single circular filter bag in the process of filter bag processing, because the filter bag should be fixed on the flower board or short pipe, some should be hung up on the bag cap, so the two ends of the filter bag need double seam sewing or even multi layer sewing: the double layer sewn has no filtering effect due to the increase of resistance, and some filter bags are also in the middle of the bag. Fixed ring, this part has no filtering effect. In large and medium air blow deduster, the filter bag is long 10m, and the diameter is 0.292m. The nominal filter area is 0.0292 * 10 = 925m; if the area 0.75m without filtration is deducted, the net filter area is 8.25-0.75 = 7.5m. It can be seen that the filtrating area of the filter bag occupies 5% to 10% of the filter bag area. Therefore, the size of the net filter area should be specified in the specifications of the large and medium dust remover. Fourth: after calculating the total filter area and the area of a single dusting cloth bag, the number of filter bags can be calculated. If the number of filter bags in each filter chamber is determined, the number of the entire deduster can be calculated from this. Although the number of rooms is determined as required in the design or selection of the dust remover, the number of seats in more than 6 rooms is often fixed as double rows from the layout and maintenance of the site. The rooms of less than 5 rooms are divided into single rows. When the filter area of bag filter is determined, the volume of air handling depends on the selection of filtration rate. The formula is: Q = V * s * 60 (m3/h). Q - handling air volume V - filtering wind speed (m/min) S - total filter area (M2) Note: filter area (M2) = treated air volume (m3/h) / (filtration speed (m/min) X60)
