Lfef Series Dryer Glass Fiber Bag Dust Collector

LFEF Series Dryer Glass Fiber Bag Dust Collector

The pulse bag filter uses a high-energy online dust removal system, combined with a deep filter medium, and can process the same amount of gas with about half of the filter area, or the air-to-cloth ratio is twice that of the old-fashioned dust collector. As a result, it is cheaper than commonly used equipment and takes up less space. Therefore, the market is optimistic. The low-pressure pulse jet bag dust collector has a fine dust air pressure of 100kPa, a large-diameter pulse valve and a pulse air distribution pipe, and the dust bag has a diameter of 130mm and a maximum length of 3m. At present, it is necessary to effectively clean dust for 5m long and longer filter bags.
The first of the three refitted dust collectors in the original electric precipitator shell of the pulverized coal boiler started operation. There is also a smaller unit installed in the power plant to process the flue gas produced by a 30MW cyclone-burning boiler. The number of pulse bag filters used in boilers around the world has greatly increased. In addition, the pulse cleaning method of the dust collector also has high pressure/small air volume, medium pressure/medium air volume and low pressure/atmospheric volume. On the 10t/h pulverized coal boiler of my country's Beijing People's Liberation Army News, a counter-jet pulse bag filter was used to purify the flue gas, and the length of the filter bag was increased to 5m. The flue gas volume of the boiler is 29635Nm3/h, the filtering area is 264m2, and the filtering speed is about 1.8m/min. The service life of the filter bag after operation is not long. Later, other filter materials were used, but practice has proved that this filter material used for boiler dust removal is also easily damaged due to poor hydrolysis resistance. The pulse bag filter has been in operation for many years and has been in good condition. The filter material is glass fiber filter material. It shows that the application of bag filter in coal-fired boilers in my country has shown bright prospects. Whether the boiler application bag filter can be successful, the main considerations are: Whether the filter material is selected properly; Whether the corresponding technical measures can be used to ensure good results for a specific condition of processing high-temperature acid gas. In addition, the design and manufacturing quality of the dust collector should also be good, and there are problems with later cleaning.
Most of the bag filters used in boilers or other production processes that produce flue gas are off-line dust removal-separating compartments during dust removal.
Dust removal is generally initiated by pressure difference, and there is a pressure difference set point that triggers the dust removal cycle. At the same time, most of them use timers as additional control means; if the pressure set point does not cause dust removal within the specified operating time , The system will be cleaned regardless of the pressure drop. Once the dust removal is started, some systems set the program to remove dust and continue until the dust-cleaned filter bag is sufficient to meet the pressure set point requirements, and the remaining filter bags are no longer dust-cleaned; other systems are The ash continues until the bag filter is completely cleaned. Generally speaking, the latter is better. However, there are some situations where the former is better. If the bag filter is completely cleaned in one cycle, it will take less time for the bag filter to clean in some compartments while the filter bags in other compartments are dusty (a condition that causes unbalanced airflow) when the bag filter is running . In some special cases, partial cleaning is better. If the opacity of the flue gas discharged by the dust collector is only at the edge of the acceptable level, when all the bag filters are cleaned, there may be dust spraying. If the dust is divided into several points, the dust spraying will not Will appear. Secondly, when the bag filter is used as part of the desulfurization system, a considerable part of the acid gas reaction may occur on the dust layer of the filter bag. In this case, complete dust removal may cause a large amount of temporary acid gas emissions, and stepwise dust removal can eliminate this phenomenon.
