How to use our filter bag


Latest company news about How to use our filter bag

Filter closed filter: The filter bag is used together with the matched filter. The system fluid pressure is used to squeeze the liquid through the filter bag to achieve the purpose of filtration. The utility model has the advantages of fast flow rate, large processing capacity and long service life of the filter bag, and is particularly suitable for occasions where large flow rate is required for closed filtration.


Self-flowing open filtration: The filter bag is directly connected to the pipe through a suitable joint, and is filtered by a fluid gravity differential. Its remarkable feature is that it does not require equipment investment, and the filtration is simple and feasible. It is especially suitable for small-size, multi-species, batch-type economical liquid filtration.


The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The dust filter is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag filter, the particles are large and the dust is large, due to gravity. The action settles and falls into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is retained and the gas is purified. Generally, 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 the effects of sieve filtration, collision, retention, diffusion, static electricity, etc., the surface of the filter bag is covered with a layer of dust. This layer of dust is called the primary layer. During the subsequent movement, the initial layer becomes The main filter layer of the filter material can rely on the action of the primary layer, and the filter material with larger mesh size can also obtain higher filtration efficiency. As the dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase correspondingly. When the pressure difference between the two sides of the filter material is large, some fine dust particles that have adhered to the filter material are squeezed past. Reduce the efficiency of the precipitator. In addition, the excessive resistance of the precipitator will significantly reduce the air volume of the dedusting system. Therefore, after the resistance of the precipitator reaches a certain value, it should be cleaned in time. The initial layer should not be destroyed when cleaning, so as to avoid the efficiency drop.


The structure of the bag filter is mainly composed of an upper box, a middle box, a lower box (ash hopper), a cleaning system and a ash discharging mechanism.


The performance of the bag filter is not only the correct choice of filter bag material, but also the deashing system plays a decisive role in the bag filter. To this end, the cleaning method is one of the characteristics of the bag filter and an important part of the operation of the bag filter.
