Causes and solutions for leakage of bag filter

Under normal circumstances, the bag filter suddenly appears to be ashing during use. We must stop the operation of the precipitator in time and immediately stop the maintenance. One of the main reasons for ash is caused by broken bags. The dust filter bag is gradually worn, and the main cause of wear is the grinding force of the dust, the deterioration of the bag caused by the high temperature and the corrosion of the chemical substance. When the grinding force of the dust is strong, the wear of the bottom of the dust bag is the most serious, the system capacity The increase in filtration rate also accelerates wear.

When most of the dust filter bags are damaged, they should be replaced completely. It is best to replace the dust bag when the dust collector stops working. At this time, the dust controller should be closed, and the manhole door at the top can be opened to disassemble the bag and disassemble. When the bag cage is removed first, then the spring ring on the upper edge of the bag is pinched into a concave shape, and the dust bag is pulled up. Before installing the new bag, the dust on the flower plate hole should be cleaned.
The dust collector cannot work with a damaged dust bag, otherwise it will accelerate the scrapping of the dust collector. When a small area of individual dust bag is damaged, in order to save money, Kodak Environmental Company recommends that the hole be filled with an old cloth bag or a new filter cloth of the same material. The hole filling method is to use a silicone rubber compound for bonding. As long as the temperature and chemical properties of the adhesive are compatible with the process conditions.

When the bag filter is “ashing”, it can be judged according to the number of bits corresponding to the electromagnetic pulse valve and the pulse controller when the air outlet is “ashing”, which is to exclude the dust filter bag from leaking. The bag filter can also use the flashlight to detect the dust filter bag from the upper case observation hole; or open the pulse cover after opening the cover, and the bag filter is found to be "ashing" from the venturi during the blowing process. That is, the dust filter bag is leaking dust. Then, according to the problem that arises.
