Diameter, and the rational use of the relevant media. Because a variety of media has its standard width, to make full use of the filter, bag diameter should be determined according to the width of the filter. For example, the width of 990 mm fabric, leaving the necessary seam take the head, can be made into two 152 mm diameter filter bag. Dust bag diameter of size is also affected. For example, at about 7.5 m² ground, with a diameter of 152 mm, length of 3 m bag filter area of about 163 m², if the diameter of 305 mm instead of the bag, you need to get the same length of 4.3 m in the same area of the ground filter area. The thickness of the bag is also aligned with the needs of the energy and pulse cleaning valve related. Conventional pulse dust collector in the longer diameter is generally 152 mm; short bag, diameter is generally 120 or 130 mm. Length, in the case of flue gas treatment capacity, same speed and dust bag filter bag diameter, length can be increased to reduce the number of bags, thus reducing the footprint, reduce electromagnetic valve cleaning system, the pulse valve, injection tube and other components saving investment, but also shorten the cleaning cycle. But not on the one hand, extended filter bag, the cleaner body also extends upward, which means you have to increase the strength, the equipment costs increase; pulse jet from the point of view, to make the dust bag full length effectively cleaning, in the end of the application must be sufficiently large injection energy, dust bag, the longer, the greater the energy requirements, bag blowing end the more fragile; dust bag lengthened to increase the weight of the filter support, and also increased tension If too much tension at the top, pull the seam may be broken; when cleaning line, the longer the bag, the more likely return from the bag dust filter bag; if off-line cleaning, the dust bag bag longer after cleaning pause time should be extended, sub-room cleaning recovery slower filtration; in addition, the bag is too long, the installation, maintenance, inspection will inconvenience; if installed in indoor dust, dust bag length but also by building height limit.
