Bag filter is a kind of dust removal equipment widely used in industrial production process, its main function is to filter dust-containing gas through filter bags to achieve the purpose of purifying the air. However, with the increase of use time, the filter bag will gradually wear out and age, which will affect the dust removal effect. The removal of the dust filter bag replacement cycle and the ash cleaning cycle are important to ensure the normal operation of the equipment.
Dust collector bag replacement cycle.
The replacement cycle of the dust collector bag mainly depends on the following factors:
1) Dust quality: Different quality of dust has different degrees of wear on the filter bag. For example, abrasive dust, high-temperature dust, etc., wear more seriously on the filter bag, and the replacement cycle is relatively short.
2) Running time: During the operation of the filter bag, it will be constantly washed and worn by dust. The longer the runtime, the greater the wear of the filter bags and the shorter the replacement cycle.
3) Filtration wind speed: too high filtration wind speed will cause the dust layer on the surface of the filter bag to be damaged, which will accelerate the wear of the filter bag. Appropriately reducing the filter air velocity can help to extend the service life of the filter bags.
4) Filter bag quality: The quality of the filter bag directly affects its service life. Choosing the most wear-resistant filter bag can effectively extend the replacement cycle.
Generally, the replacement cycle of bag filter bag is 1-3 years. However, the specific replacement cycle needs to be adjusted according to the actual situation.
2.Baghouse cleaning cycle.
The baghouse cleaning cycle depends mainly on the following factors:
1) Dust quality: the stickiness and humidity of the dust will affect the ash cleaning effect. Larger, higher humidity dust tends to adhere to the surface of the filter bag and requires more frequent cleaning.
2) Filtration air speed: too high filtration wind speed will cause the dust layer on the surface of the filter bag to be too thick, which will affect the ash cleaning effect. Appropriately reducing the filtration air speed can help to improve the cleaning effect.
3) Cleaning method: Different cleaning methods have different effects on the cleaning cycle. For example, compared with the reverse blowing method, the cleaning effect of mechanical rapping and pulse injection cleaning methods is better and the cycle is longer.
Generally, the cleaning cycle of the bag filter is 3-6 months. However, the specific cleaning cycle needs to be adjusted according to the actual situation.
