Direct influencing factors of dust collector filter bag selection:

1. The cleaning pulse energy and the arrangement of the pulse valve directly affect the diameter of the filter bag. The diameter of the usual pulse industrial dust collector is 120mm~152mm.

2. The size of the dust filter bag must be related to the size of the dust collector. For example: on the floor of 7.5 square meters. Using a cloth bag with a diameter of 15.2mm, L=3m, filter S=163 square meters, but if it has a diameter of 1305mm, it needs a length of L=4.3m to obtain the same filtration area on the ground of the same area.

3 The width of the bag will also affect the diameter of the bag, each filter material has its scale and width, want to be used to achieve large, the width of the bag will determine the bag directly. For example, the width of the cloth bag is about 990mm, and the sewing head left behind can be made into two filter bags with a diameter of 152mm.

What factors affect the length of the dust filter bag:

1. Under the condition that the filtration wind speed and diameter of the dust removal filter bag are the same; Reduce the number of filter bags and the area of the equipment, then the length of the dust filter bag lengthened, so that the filter area of a single bag will become larger, the dust removal effect will not change.

2. Reduce the number of filter bag strips, dust cleaning system solenoid valve, pulse valve, blow pipe and so on will be relatively reduced, so as to save investment, but also shorten the dust cleaning cycle of dust collector.

3. The long length of the dust filter bag will make the cost become high. The dust removal box in the industry should also increase the height, and the strength of the components should be increased in the upward extension process, so the cost of the equipment manufacturing will increase.

4. The cleaning effect is poor: when the industrial dust collector bag is cleaned online, the longer the filter bag is, the more likely it is that the dust blown out of the bag will be adsorbed again. If off-line cleaning, the longer the cloth bag, the longer the pause time after cleaning, the slower the cleaning chamber recovery filtration;

5, the bag is easy to damage: the longer the dust filter bag, in order to ensure the effective cleaning effect, the more powerful the need to maintain a jet energy, the greater the potential energy, the more easy to damage the dust filter bag;

6. If the filter bag is too long, installation, maintenance and inspection will be inconvenient. From the history of industrial precipitator, the diameter of the cloth bag commonly used in industrial precipitator is generally between 120mm and 152mm, while the length of the filter  bag is getting longer and longer with the development of technology, from 3.6mm in the 1950s to 8-10m in recent years.
