With the advantages of high dust removal efficiency, low energy consumption, simple process principle, and adaptability to different types of coal, the bag dust collector is widely used in the flue gas treatment of thermal power plant boilers. During the dust removal process using the bag filter, it is necessary to understand the factors that affect the service life of the filter bag, so that the user can take timely measures such as inspection, maintenance and maintenance to increase the service life of the bag filter.
Factors affecting the service life of the bag dust collector: First, the effect of the filter bag material; the filter bag material should be selected to block the passage of fine dust, the perforation of the fabric warp and weft is small, the warp and weft lines are thin, the fabric fluff is long and flexible, and can cover the eye. And has a certain strength. Second, the impact of high temperature on the filter bag. When the exhaust temperature exceeds 160 ℃, the temperature has a significant effect on the life of the filter bag. As the temperature increases, the loss of the filter bag 0010010 #39;s life gradually increases, and the filter material will be burned when it reaches a certain temperature. Therefore, the exhaust temperature should be strictly controlled during operation to prevent long-term over-temperature operation and sudden temperature rise accidents in a short time. 3. The effect of filtration air velocity on the filter bag. Filter air speed is an important factor that determines the performance of the dust collector. For dusty flue gas with high dust concentration, fine particles and high abrasion, the filtering wind speed should be smaller, otherwise the higher wind speed should be selected. 4. The impact of destructive cleaning on the filter bag. In order to keep the pressure difference of the filter bag at the designed value, the fly ash attached to the surface of the filter bag should be cleaned regularly.
