There may be various reasons for smoke and ash emission from bag filters, and the following are some common reasons for analysis:
1. Bag damage: If the bag is damaged, dust and gas will directly enter the discharge port, leading to smoke and ash. At this point, it is necessary to replace the cloth bag.
2. Incomplete cleaning of cloth bags: After long-term operation, some dust will adhere to the cloth bags. If the cleaning is not thorough, excessive accumulation of dust can lead to blockage, making it impossible for dust to pass through the cloth bag, resulting in smoke and ash from the discharge port. At this point, it is necessary to thoroughly clean the cloth bag.
3. Loose bag: If the bag is stored for too long or accidentally touched during operation, it can cause the fixing parts of the bag to loosen, causing dust to bypass the bag and directly enter the discharge port, leading to smoke and ash. At this point, it is necessary to re secure the cloth bag.
4. Unstable inlet air volume or temperature: Unstable inlet air volume or temperature can also cause smoke and ash. At this point, it is necessary to check whether the ventilation system and pipelines at the inlet of the dust collector are normal.
In summary, to solve the problem of smoke and ash emission in the bag filter, it is necessary to conduct timely testing and maintenance to ensure the integrity, cleanliness, and fixation of the bag, as well as to ensure the stability of the inlet air volume and temperature.
