The short life of the dust removal filter bag affects the life of the use of the filter bag as follows: Improper use of the filter bag; the quality of the filter bag; filtering air; dust load; dust composition; dust characteristics; cleaning method; cleaning frequency; , Times; and related maintenance work. When evaluating the life of the filter bag, you should consider whether it is improperly used, carefully check and record the work conditions of the dust collector. Whether the dust collector is often turned on, shut down, and whether the pulse cleaning period and the cleaning time are reasonable. Measures and thermometers are prerequisites for ensuring records. It is also a measure to ensure the normal operation of the dust collector.
Reasons for the moisture of the filter bag: The dust collector's shell is not sealed and leaked, entering the wet air, and the compressed air used to reflect the ash is not clean (oil, water), and the compressed air used for clear gray is too cold. In order to prevent the filter bag from moisture, in the cold areas, compressed air used in the ash can increase insulation, heating, oil removal, and water removal, and continue to clear the ash for 10 ~ 20 points after the dust collector is shut down. Moisture is a large cause of the blockage of the filter bag. The cause of water containing water is usually low -temperature condensation. Especially when dealing with burning or high temperature flue gas, the following methods can be used to prevent:
1. Avoid improper booting
2. Avoid booting when the dust collector resistance is large; turn on when it is lower than the dew point; reopen when the filter bag surface of the filter bag is stopped at the surface of the dust collector. Milid. In order to prevent this situation, preheating dust collectors should be imported dusty air, or pre -covered dust layer.
3. It is prone to problems that are lower than the dew -point booting cleaner than the dew point. If the intake distribution is uneven, it is easy to cause local corrosion of the dust collector's shell. Therefore, the dust collector should be avoided below the dew point. The insulation device should be used.
4. The air infiltration of the air infiltration of air infiltration often occurs in the flange, maintenance door or dust collector of the dust collector. If the seal is not tight, the external air enters the dust collector. When it is treated with high temperature waste gas, it will generate a low temperature area inside the dust collector. As a result, the low temperature is exposed, the corrosion of the dust collector, and the moisture of the filter bag.
