The cost of dust bag is not high, but because of its use characteristics, timely a high-quality dust bag average life expectancy is 2 to 5 years, if the selection is not appropriate or improper use will reduce its life, If you always replace the dust bag, the cost is quite considerable, so we need to understand the main trouble of dust bag and avoid the method:
First, burned: cause the cause of the dust burner bag burned, mainly dust bag surface of the initial layer thickness is not enough, the temperature of the flue gas is too high to. If the dust collector long-term treatment of the flue gas temperature exceeds the working conditions of the bag, easy to dust bag shrinkage,
Or melt to create holes. If the thickness of the initial layer is not enough, smoke in the smoke into the smoke, or dust heat, dust bags may also make holes. Resulting in dust bag burned mainly reflected in the new replacement on the dust bag. As the online replacement is not pre-coated ash, high temperature flue gas carrying Mars directly touch the bag, easy to dust bag damage. To prevent burnout measures: Ensure that the initial layer thickness of the dust bag surface. To ensure that the exhaust temperature is not over temperature (# 3, # 4 furnace control standards are not higher than 180 ℃).
Second, wear: wear dust bag mainly occurs in the middle of the dust collector, in a single dust bag mainly in the bag from the export of 1 meter range. The main reason for the uneven distribution of flue gas in the middle of the single room flow rate is too high, in a single dust bag on the export
At the filter gas velocity is too high, resulting in dust impact, wear bags, but also to dust bag fabric fiber tension damage, easy local bag perforation, the use of the cycle is too short. For the frequent wear parts of the dust bag replaced with wear-resistant bags.
Third, the distance between the dust bag is too small, keel bending and so easy to cause wear between the bags. The difference between the diameter of the bag and the keel is too small, and the cleaning effect is too small, which will cause the cleaning cycle to be shortened and the pressure of the blowing air. When the bag is too large, the friction between the bag and the keel will accelerate. For some filter cloth with temperature changes, and there are elongated characteristics, need special attention.
Fourth, keel welding at the hole or burr, or corrosion due to the rough surface, will also accelerate the wear of the bag. Bags and perforated plate seal is not strict, will cause the top of the bag at the fold wear.
5, Venturi tube or pulse tube relative to the bag alignment is not correct, easy to make the injection pipe spray airflow directly to the upper part of the bag to produce wear and tear. Bag cleaning too often, will accelerate the wear of the bag.
Six, too high filtration rate, will make the initial dust layer broken, and dust impact bag caused by excessive wear and tear, if the time is too high cleaning bag can easily lead to loose fabric bag, to speed up the wear and tear bag. Flue gas dust in the design standards, but also make the bag to accelerate wear. Small ash bucket too much ash, resulting in smoke in the smoke chamber dust over the General Assembly to speed up the wear and tear of the bag.
7, to reduce the wear measures: dust bag in the production process, the dust bag of the weak parts of the thickening; bag in the installation process, the distance is too small, keel bending bag to adjust the replacement; dust bag and keel with the appropriate (+10 ~ 20 mm), and the length should be consistent; keel in the use should be strictly checked, broken keel is strictly prohibited to use; dust bag and perforated plate seal should be checked tightly leak; venturi tube and pulse tube correct. In the course of running, to prevent the filtration rate is too high, the bag cleaning cycle is too short, blowing compressed air pressure is too high factors. In the set dust filter pulse cleaning cycle, in order to ensure that the dust collector work in a stable pressure, set the pulse cleaning cycle time as long as the pulse cleaning time to ensure that the initial dust does not fall off, set the time Cleaning the shortest as well, if the beginning of the dust layer is not enough, you can use to extend the cleaning cycle supplement, if the use of differential pressure control, you can improve the stability of the import and export pressure regulator set.
