The dust bag is mainly made of a textile filter cloth or a non-woven felt during the production process. The product mainly uses the filtering action of the fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the entire product particles Large and major dust settles down due to the action of gravity and falls into the ash bucket.
When the dust bag is used, gas containing fine dust passes through the filter material and the dust is retained. This will result in purification of the gas. In general, the dust removal efficiency of the new filter material is not high enough. After the filter material is used for a period of time, due to effects such as screening, collision, retention, diffusion, and static electricity.
A layer of dust is accumulated on the surface of the dust bag. This layer of dust will be called the initial layer. During the subsequent movement, the primary layer becomes the main filter layer of the filter material, depending on the role of the primary layer, the mesh Larger filters can also achieve higher filtration efficiency.
Dust bag will be effective with the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust filter will increase accordingly. When the pressure difference between the two sides of the filter is large, some of the dust will adhere to the filter material. Dust particles squeezed in the past, making the efficiency of the dust collector drop.
The bag filter structure mainly consists of an upper box, a middle box, a lower box (ash bucket), a dust removal system, and a ash discharging mechanism. In addition to the correct selection of filter bag material, the dust removal system plays a decisive role in the bag filter. For this reason, the method of dust removal is one of the characteristics of the zone bag filter, and it is also an important part of the operation of the bag filter.
