Designing your dust collector correctly from the start is the best way to prevent damage to your bag.
When designing the dust collector system, considering the service life of the filter bag, it is necessary to analyze the use environment of the dust collector in detail.
After installing the dust collector, we should develop a proper set of dust collector maintenance and maintenance plan to ensure the life of the filter bag. By monitoring things like dust collector pressure drops, we can spot small problems before they become big problems.
Minimize bag damage after the collector is in operation. Bag replacement is often the biggest expense in baghouse system operations, so if you can extend the life of your filter bags, you can save a lot of money, and damaged bags can also cause system downtime that can have a significant impact on your plant.
The following are the main reasons for damage to the dust bag and how to fix it:
Typical baghouses and filter bags are not suitable for use in wet environments. If there is too much moisture, it may cause the dust bag to clog and the dust bag to fail prematurely. Moisture can also cause dust to accumulate on other parts of the collector, including the inner wall, piping system, pressure sensors, and the blades of the hopper rotary valve, which can cause the rotary valve to get stuck.
Even a small amount of moisture can cause big problems. Common causes of moisture inside a baghouse include:
Humidity The change in temperature.
Hygroscopic dusts (salts, sugars, metal oxides, etc.).
Moisture enters the dust collector through poor seals such as dust collector access doors.
Compressed air is moist or watery.
Since wet oily air is usually the problem, if the air is humid, you can use a dryer to remove moisture from the air, or a separator to remove oily particles.
Although the dust bag needs to be cleaned regularly, too much cleaning may cause the bag to be damaged prematurely. When the pulse frequency of the dust bag exceeds its required pulse frequency, it may cause the dust bag to appear small tears and gradually become a bigger and bigger problem. If you clean the dust bag under too high pressure, for example it should be only 0In the case of 4MPa, it reaches 08MPa, this can also happen.
