Reasons and solutions for the damage of the dust filter bag


Filter bag dust removal equipment is a dry dust removal device, which can not only capture fine dust and purify flue gas, but also help waste gas recycling. In the entire dust removal process, the dust filter bag is the most important dust removal tool. It directly affects the dust removal effect of the entire system, but its cost is also slightly higher, and it is easy to be damaged due to direct contact with the flue gas for a long time, so find out the cause of the damage And solving is the best way to save costs and ensure man-hours.
 



The main reasons for the damage of the dust filter bag are generally as follows:
1. Filter wind speed
The filter wind speed of the bag filter is too high, which is the main reason for the damage of the dust filter bag. In recent years, some units have blindly reduced equipment costs and increased profits. When designing a bag filter, the filter wind speed was increased. There was no obvious response from the user in a short time, but the service life of the filter bag was shortened. In this way, instead of saving money for customers, it has brought a very large economic burden and wasted time.
 
2. Dust medium
The choice of cloth for the dust collector bag depends on the dust nature of the dust, and consider whether the dust contains acid, alkali or strong corrosive substances. According to the nature of the dust, select the filter material that is suitable for it, so that the filter bag can absorb the dust normally without affecting its service life.
 
3. Operating temperature
Correct selection of dust filter bags suitable for the corresponding dust temperature is the key to filter bags. If the temperature is too high, the selected dust filter bag exceeds the normal use temperature, the filter bag will shorten the service life, and the serious will be burned in a short time. Therefore, when selecting the filter bag, the temperature of the dust collector should be measured and calculated, and the corresponding dust filter bag should be selected.
 
4, product quality
The processing of cloth bags is particularly important. In recent years, some small manufacturers have adopted small sewing machines as processing equipment, and used low-quality thread as raw materials during processing. It will cause the filter bag to appear cracked, cracked, and dropped after the use time is not long. Although the cloth bag size is slightly smaller, it can be used, but after the dust with a larger specific gravity is absorbed, the bag will fall off after a period of use.





Most of the damage to the dust filter bag is caused by physical reasons, so it is necessary to pay more attention to the installation and use in order to avoid it as much as possible. The method is as follows:
 
1. Renovate the dust removal frame, adjust the installation method of dust removal filter bag, improve the working quality of hanging dust removal filter bag, and ensure that the dust removal filter bag can be prevented from being damaged during disassembly and assembly.
2. Pay attention to the lubricity of the internal components of the filter bag dust collector to prevent sharp tools from damaging the dust filter bag.
3. Adjust the dust removal cycle and dust removal method of the filter bag dust removal equipment to prevent the dust removal from causing damage to the dust filter bag.
4. Adjust the wind speed appropriately to prevent the dust filter bag from being damaged due to excessive wind speed.
5. Control the inlet temperature, add a temperature control device to ensure the temperature is moderate, and improve the material of the dust filter bag so that the dust filter bag can work normally when the temperature control fails.
 


 
The replacement of the dust filter bag will increase the cost and affect the working hours. Therefore, in order not to delay work and save money, it is necessary to prevent the dust filter bag from being damaged and extend its service life as much as possible.
 



In the process of dust removal, if dust is found at the outlet of the dust removal equipment, it is likely that the dust removal filter bag is damaged. At this time, stop the operation and check; the dust removal filter bag accounts for about 30% of the cost of the dust removal equipment, so Replacing the dust filter bag will affect the cost of the entire dust removal equipment. Therefore, avoiding damage to the dust filter bag as much as possible is the key to ensuring the progress of the project and saving costs.
