Development Trend of Dust Removal Skeleton

The development trend and application scope of the dust removal frame
can be used in different heavy metal industries, and it plays an important role and contribution. The electrolytic aluminum industry mainly uses dust removal frame flue gas purification technology. With the increase of electrolytic cells, There are also more and more dust removal frameworks that can handle 10,000 to 10,000/air volume. Bag dust collectors should be used for flue gas purification in lead, zinc and other tempering furnaces. Overall, the transformation work of the non-ferrous metallurgical industry is arduous, so the dust removal framework The dust removal technology that requires a larger dust structure can effectively ensure that it plays an important role in dust removal operations. The bag dust collector determines the filter bag filtration area according to the selected filtration wind speed, and its filter bag filtration area is not affected at all. The amount of waste or dust concentration affects the dust bag. It is made of textile filter cloth or non-woven felt. The filtration effect of fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the particles are large. Heavy dust settles due to gravity and falls into the ash hopper. When gases rich in finer dust pass through the filter material, the dust is retained, allowing the gas to be purified. High temperature, high humidity, highly corrosive framework and filter material The modification of fiber filter materials and the expansion of applicable areas, the cleaning capabilities of dust cleaning equipment, the development and application of large pulse valves, reducing the use of pulse valves, dynamic control expert systems for different filter materials, and the development of domestic fibers to meet the needs of power plants , The service life of the filter bag for waste incineration flue gas purification requires that the dust removal efficiency of the new filter material of the dust collector skeleton is not high enough. After the material is used for a period of time, due to effects such as screening, collision, retention, dispersion, and static electricity, the surface of the filter bag accumulates A layer of dust, this layer of dust is called the first layer. In the subsequent movement process, the first layer becomes the main filter layer of the filter material. Relying on the function of the first layer, filter materials with larger meshes can also obtain higher efficiency. The frame of the filter bag is the rib of the filter bag. It should be light and easy to install and maintain. The quality of the structure directly affects the filtration status and service life of the filter bag.
