Industrial dust collection bags specifications include the diameter of the dust collection bag and the length of the dust collection bag
The factors affecting the diameter of industrial dust collection bags are:
1. The diameter of dust collector dust bag is related to the cleaning pulse energy and the arrangement of the pulse valve. The diameter of ordinary pulse industrial dust collector is usually between 120 mm and 152 mm.
2. The diameter of the dust bag is related to the size of the dust collector. For example, a dust filter bag with a diameter of 152 mm and a length of 3 m is used on a floor of about 7.5 square meters and has a filtering area of about 163 square meters. If a filter bag with a diameter of 305 mm is used, its length is 4.3 m in order to obtain the same filter area on the same area of the floor.
3. The diameter of the dust collector dust bag is related to the width of the filter media. Various different filter media have their scale widths. To maximize utilization, the diameter of the dust collector dust bag will be determined by the width of the filter media. For example, a fabric with a width of approximately 990 mm can be made into two filter bags with a diameter of 152 mm.
Factors that affect the length of industrial dust collection bags are:
1. Reduced number of dust bags and smaller equipment area: When the processing air volume, filter air speed and filter bag diameter are the same, the length of dust bags will increase, increasing the individual filter area dust collection bags, thus reducing the number of filter bags and reducing the floor space.
2. The number of dust bags is reduced, so it also reduces the solenoid valve, pulse valve, blowing tube and other parts of the dust collection system, which saves investment and shortens the dust collection cycle of the dust collector.
3. Excessively long dust bag will increase the manufacturing cost: the height of industrial dust collector box will increase, and the upward extension will increase the strength of the components, so the equipment manufacturing cost will increase.
4. Poor dust cleaning effect: the longer the dust bag is when the industrial dust collector is online, the greater the possibility that the dust blown out of the dust bag will be re-absorbed into the bag; if the dust is removed in the offline state, the placement time of the filter bag will be longer. The hanging time should also be extended, and the recovery and filtration speed of the cleaning chamber will also be slower.
5. Dust collector dust bag is easily damaged: the longer the dust bag is, the stronger the blowing energy must be maintained in order to ensure effective dust removal. The higher the blowing potential energy, the easier the dust bag will be damaged.
6. If the filter bag is too long, it will bring inconvenience to installation, maintenance and inspection.
From the development history of industrial dust collector, the diameter of the common bag of industrial dust collector is generally between 120 mm and 152 mm. With the development of technology, the length of dust collector bags is getting longer and longer, from 3.6 mm in the 1950s to 8-10 m in recent years.
In short, to determine the specifications of the industrial dust collection bags must not only meet the requirements of air filter volume and equipment cleaning methods, but also consider the actual site conditions and comprehensive consideration to achieve a reasonable design.
The above is a detailed description of the factors affecting the specifications the industrial dust collection bags, I hope the above can help you better understand and use dust removal equipment.
