How to choose the number of bags for f5 bag air filter?
How to choose the number of bags for f5 bag air filter?Calculation of f5 bag air filter:First: dust bag processing air volume is the volume amount of gas that can be purified by the dust removal equipment in a unit of time. The unit is cubic meters per hour (m3/h) or standard cubic meters per hour (Nm3/h). It is one of the **important factors in the design of a baghouse dust collector. According to the air volume design or selection of baghouse dust collector, generally can not make the dust collector in more than the specified air volume operation, otherwise, the filter bag is easy to clog, shorten the life of the pressure loss rises substantially, dust removal efficiency should also be reduced; but also can not be selected air volume is too large, otherwise increase the investment in equipment and floor space. Reasonable selection of processing air volume is often based on process conditions and experience. Second: calculate the total filtration area: according to the total volume of gas through the dust collector and the first set of filtration speeds, according to the following formula to calculate the total filtration area: after the total filtration area, you can determine the overall size of the baghouse dust collector scale and size. Third: according to the area of a single round filter bag in the filter bag processing process, because the filter bag to be fixed in the flower plate or short tube, and some also hang up and fixed in the bag cap, so the ends of the filter bag need to be double sewing or even multi-layer sewing: double sewing of this part of the resistance to increase the role of filtration has been no filtering, and at the same time some of the middle of the filter bag to be fixed in the middle of the ring, the part of the filtration is no filtering effect. Large and medium-sized reverse air dust collector, the filter bag length of 10m, diameter of 0.292m, its nominal filtration area of 0.0292 × 10 = 925m, if deducted the area of no filtration effect of 0.75m, the net filtration area of 8.25-0.75 = 7.5m. It can be seen that the bag is not useful for the filtration area accounting for the bag area of 5% to 10%, so, in the large and medium dust collector Specification should indicate the size of the net filtration area. Fourth: After finding out the total filter area and the area of a single dust bag, you can calculate the number of filter bags. If the number of filter bags in each filter bag chamber is determined, the number of chambers in the whole dust collector can also be calculated from this. Although in the design or selection of dust collector according to the need to determine the number of chambers, from the site layout and maintenance convenience considerations, often more than 6 chambers in addition to the number of chambers of the sitter as a double row, less than 5 chambers of the dust collector of the chambers as a single row. |
