The characteristics of long life of polyester filter cloth, especially suitable for the occasions that need to seal large flow
Polyester filter cloth : Filter bags are used with matching filters. The system fluid pressure is used to squeeze the liquid through the filter bag to achieve the purpose of filtration. It has the characteristics of fast flow rate, large processing capacity, and long service life of the filter bag. It is especially suitable for occasions where large flow rates need to be sealed.
Self-flowing open filtration: The filter bag is directly connected to the pipeline through a suitable joint and filtered by the difference of fluid gravity. Its distinguishing feature is that it does not require equipment investment and filtering is simple and feasible. It is particularly suitable for small, multi-variety, intermittent economical liquid filtration.
Bag filters are dry filters. It is suitable for capturing fine, dry, non-fibrous dust. Filter bags are made of woven filter cloth or non-woven felt. Filter dust filter by filtering effect of fiber fabric. When the dust-containing gas enters the bag filter, the particles are large and dusty due to gravity. The movement is stable and falls into the ash bucket. When a fine dust-containing gas passes through the filter material, the dust is retained and the gas is purified. In general, the dust removal efficiency of new filter materials is not high enough. After using the filter material for a period of time, the surface of the filter bag is covered with a layer of dust due to the effects of filtration, collision, retention, diffusion, static electricity, etc. This layer of dust is called the main layer. In the subsequent movement process, the main filter layer whose initial layer becomes the filter material can depend on the role of the main layer, and the filter material with a larger mesh size can also obtain higher filtration efficiency. When dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increases accordingly. When the pressure difference between the two sides of the filter material is large, some fine dust particles attached to the filter material are squeezed over. Reduce the efficiency of the dust collector. In addition, the excessive resistance of the dust collector will significantly reduce the air volume of the dust removal system. Therefore, after the resistance of the dust collector reaches a certain value, it should be cleaned in time. The initial layer should not be damaged during cleaning to avoid reducing efficiency.
The structure of the bag type dust collector is mainly composed of an upper box, a middle box, a lower box (ash hopper), a cleaning system and an ash discharge mechanism.
The performance of the bag filter is not only the correct choice of filter bag materials, but the ash removal system plays a decisive role in the bag filter. For this reason, the cleaning method is one of the characteristics of the bag filter and an important part of the operation of the bag filter.
