How to avoid the "buck bag" of the pulse bag type dust collector, the pulse bag type dust collector sometimes has bag hanging phenomenon during operation. What should I do in use? The bag filter should prevent the gas from cooling below the dew point in the bag room, and the bag filter should pay more attention to the negative pressure. Sometimes the housing of the bag filter is not tightly divided, and the air temperature in the bag room is lower than the dew point, causing the bag to get wet. At this time, Dust will stick to the bag. The permeability of the bag is seriously reduced, making the bag filter difficult to clean. If the resistance is too high, the bag filter will burn out. In severe cases, the bag filter will not work. Cause this situation There are many reasons.
1. The humidity entering the bag filter is very high, and the temperature is very high, which will generate a lot of steam, which will cause the bag filter to impact and stick to the bag. Pulse bag type dust collector "buck bag" avoiding method
Treatment method: Reasonably control material humidity. Material drying can be suspended. For example, the moisture content of various raw materials (limestone, clay, iron powder), fuel (coal), and mixed materials (gypsum, slag) required for cement consumption is different. If stacked in a fixed rectangular storage shed, if it is protected from rain , The water content of the material will be greatly reduced. This is an effective measure to reduce the water content of the material. It can also stop the drying of raw materials, fuels and mixed materials to dry the water; you can also install drying equipment to stop drying the mixed materials to reduce the water content .
2. The bag type dust collector has poor insulation and air leakage. The outside air flows into the inside of the vacuum cleaner to change the internal temperature. The leakage of cold air greatly reduces the temperature of the vacuum cleaner, thus forming a paste bag of the filter bag.
Treatment method: reduce the air leakage of the vacuum cleaner, and do a good job of heat preservation of the vacuum cleaner. The air leakage of the vacuum cleaner should be controlled below 3%.
In the dust removal system, it is necessary to control the center that is easy to leak: the closed ash discharge valve at the discharge port, the closed ash discharge valve under the dust collector, air leakage, pipe flange joints, manhole doors, etc. Gas does not constitute serious dust pollution in this post, and the technical staff and employees of some companies often do not pay attention to its impact. These are often ignored by maintenance and management personnel, thereby increasing unnecessary air leakage, deteriorating the operating conditions of the bag filter, and causing corresponding condensation phenomena.
3. When the temperature of the dusty flue gas is too low, and the temperature of the flue gas after the dust collector is close to or lower than the dew point temperature, exposure will occur.
Disposal method: Do a good job of heat preservation and rain prevention in vacuum cleaners, pipes and other related places. According to the practice of our company, the theory proves that good insulation measures can make the temperature difference between the inlet and outlet of the bag dust collector small, which is an effective measure to prevent condensation. In addition, good insulation can make the temperature difference between the inlet and outlet of the dust collector less than 20 ℃. When the inlet temperature is 25 ° C higher than the dew point of the flue gas, the dust collector operates stably. Dust-containing gas should be evenly distributed in the dust collector to prevent eddy currents at the corners from causing condensation problems, reduce the amount of gas passing through the dust collector, and form a local low temperature. How to Avoid "Bags" in Bag Dust Collectors
4. The dust bag does not have the characteristics of waterproof and anti-condensation. Due to the large moisture content of the material in the waste milling section of the material, the equipment and pipes are easily blocked, and the dust bag is easy to dew and paste, and the dust removal effect is poor.
Treatment method: Selecting a dust collector bag with waterproof and anti-condensation performance can greatly reduce the condensation and paste bags formed by the dust collector. At the same time, it is necessary to strengthen the daily maintenance, management and inspection of the vacuum cleaner, and find that no one is concerned to deal with it in a timely manner.
