In the process of using the filter bag, it is mainly used together with the matched filter. In the operation, the pressure of the system fluid is mainly used to efficiently squeeze the liquid through the filter bag so as to achieve the purpose of filtration. With the advantages of high flow rate, large processing capacity and long service life of filter bags, it is especially suitable for occasions where large flow rates need to be sealed.
The filter bag will be effectively connected to the pipe through a suitable joint to a certain extent. During operation, it can be filtered by the gravity pressure difference of the fluid. The filter bag is directly connected to the pipe through a suitable joint and is filtered by the gravity pressure difference of the fluid. Its remarkable feature is that it does not require equipment investment, and filtration is simple and feasible. It is particularly suitable for small-size, multi-species, and intermittent economical liquid filtration.
When the filter bag is operated, when the dust-laden gas enters its bag filter, the dust with large particles and large specific gravity will be settled down to some extent due to the action of gravity, and it will fall into the ash hopper and contain finer dust gas. When passing through the filter, dust is trapped and the gas is purified.
The dedusting efficiency of a new filter is generally not high enough. After the filter material is used for a period of time, due to the effects of screening, collision, retention, diffusion, and static electricity, the surface of the filter bag gathers a layer of dust. This layer of dust is called the primary layer. After this, the initial layer becomes The main filter layer of the filter, relying on the role of the initial layer, the filter material with larger mesh can also obtain higher filtration efficiency.
The filter bag will effectively collect with the dust on the surface of the filter material. The efficiency and resistance of the filter will increase correspondingly. When the pressure difference between the two sides of the filter is large, some of the filter bag will adhere to the filter media. Dust particles are squeezed in the past, which reduces the efficiency of the dust collector.
