What is the reason for the strong drop in the broken filter bag of the cement mill dust filter bag
There are several reasons for the failure of dust filter bags: A, burning. High temperature burning is the main reason of the flue gas temperature over the filter bag to allow maximum limit temperature even in flue gas with a flame, intuitive performance for the filter bag melted coking or hole. Second, the corrosion. Cloth bag dust catcher by the corrosion damage of the most obvious characteristics of filter bag in the strength of the whole, main show is in the coal-fired power plant flue gas dust removal of acid corrosion and oxidation corrosion lead to filter bag can withstand load, such as to lose filtering performance and failure.
The length of the filter will wear out and reduce dust removal efficiency
Wear and tear. There are three reasons for the wear of cloth dust filter bags: The distribution of air turbulence is uneven. The distribution of air turbulence results in the area of the filter bag which has a high velocity of dust vapor, which causes the filter bag to wear down and the life expectancy decreases. The gas filtration rate is high. Too high a filter speed can cause a lot of dust, and the fabric fibers of the filter are easily damaged. The filter bag is too small. In the lower part of the filter bag, the abrasion is more common, the wear is more than one side, the lower part is the most serious, the upward gradually reduces, the local sewing thread will be ground broken.
Jam. The main reasons for the failure of bag filter bag are: The oil is in a jam. Oil mist blockage mainly boiler start-up and low load operation for oil fuel, not the filter bag protection or protection does not reach the designated position, this will lead to the residual resistance increase of filter bag, even the powerful soot cleaning is difficult to solve this problem. Dust jam. In the process of filter bag dust collector of fine dust can enter into layers of filter bag, but when the ash removal is not possible to these all back into the inside of the filter bag dust filter bag outside, so after years of running the residual resistance of filter bag will continue to increase, in addition low boiler load for a long time when the filter is not clear ash can also lead to the emergence of the problem.
