Control the cycle and time of ash cleaning. Ash cleaning of dust collectors is an important factor affecting dust - collection performance and operating conditions. It is related to the adopted ash - cleaning method and the nature of the dust, so it should be determined according to the nature of the dust and the dust concentration. If the ash - cleaning time is too long or the intensity is too high, the dust layer attached at one time will be removed, and it is easy to cause leakage and damage to the dust - removal bags. Therefore, the ash - cleaning time and intensity should be set within a proper range. If the ash - cleaning time is too short, the dust on the dust - removal bags has not been completely removed before the dust - collection operation resumes, which will cause the resistance to recover quickly and gradually increase.
Reasons for the Blockage of Filter Bags in Dust Collectors
(1) Air leakage or low flue gas temperature causes dew formation, pipeline water leakage, and wet bags, resulting in dust sticking. (2) Excessive filtration speed, dust that is too fine or too coarse, sticky dust, and poor bag cleaning. (3) Too short jet - cleaning time and cycle. (4) Too low jet - cleaning pressure, weak jet - cleaning.
The above four points are the reasons for the blockage of dust - removal filter bags in dust collectors. Hope it helps!
