What are the specifications of dust filter bag? The common specifications are 120~160mm in diameter and 2~6mm in length. For example, round bag Φ125*1000, Φ125*1500, Φ125*2000, Φ125*2500, etc., Φ133*1000, Φ133*1500, Φ133*2000, Φ133*2500, etc.

First of all, the length of the filter bag, with the same volume of flue gas, filtration speed and diameter of the dust bag, can reduce the number of bags by increasing the length of the dust bag, thus reducing the floor space, reducing the solenoid valve, pulse valve, blowing tube and other parts of the dust cleaning system, saving investment and shortening the dust cleaning cycle. But on the other hand, the bag is longer, the dust collector box should also be extended upwards, the strength of its components will have to be increased, so that the equipment costs increase; from the pulse blowing point of view, to make the dust bag full length to get effective dust cleaning, must be applied in the blowing end of a large enough energy.
The longer the dust bag, the greater the energy required, the more likely to damage the end of the filter bag blowing; dust bag longer, supported by the weight of the filter material increased, the tension also increased, if the top of the bag tension is too large, may be pulled through the seam; online cleaning, the longer the bag, the greater the possibility of dust from the bag to return to the bag; if offline cleaning, the longer the dust bag, the longer the time to pause after cleaning, cleaning the dust In addition, the bag is too long, then installation, maintenance, inspection will be inconvenient; dust collector if installed indoors, dust bag length is also limited by the building height.

1. Reduce the number of dust bag, the equipment covers an area of small: In the case of the same air volume, filtering wind speed and bag diameter, the increase of dust bag length will increase the filtration area of single dust bag, then the number of filter bags can be reduced and the footprint can be reduced:.
2. The number of dust bag is reduced, then the solenoid valve, pulse valve, blowing tube and other components of dust cleaning system will be reduced, saving investment, and can shorten the dust cleaning cycle of dust collector.
3. Room temperature bag dust collector dust bag length is too long will add the production cost: industrial dust collector box height to add, upward extension will make the component strength needs to increase, so the equipment production cost cost will add.
4. Poor dust removal: industrial dust collector online dust removal, the longer the dust bag, the dust blown out of the dust bag is re-absorbed from the bag, the greater the possibility of the bag, assuming offline dust removal, the longer the dust bag, the greater the energy required, the more easily damaged the filter bag blowing end; dust bag longer, the weight supported by the filter media increased, the tension also increased, if the top tension of the bag is too large, may be pulled through the seam; online When cleaning, the longer the filter bag, the greater the possibility of dust returning to the filter bag from the filter bag.
