Resolution method of filtration accuracy of filter bag


The liquid flows from the inside to the outside of the bag, and the filtered particles are trapped in the bag. 

The working principle of bag filtration is pressure filtration. 

Bag filter system mainly includes three parts: filter container, support net basket and filter bag. Usually PE/PP filter bag filtration precision unit is in how many "micron" (m), and nylon mesh, stainless steel mesh filtration precision unit is in how many "mesh". "Mesh" refers to the number of holes in the screen per square inch (1 inch 25.4mm), 50 mesh refers to the number of holes per square inch, 500 mesh is 500, the higher the mesh number, the more holes; In addition to representing the holes of the sieve, it is also used to represent the particle size that can pass through the sieve. 

The higher the mesh number, the smaller the particle size. 

From the definition of "eye" can see above, the size of the aperture and the filter cloth woven with the diameter of the yarn, in be used actually, documentary silk, multifilament yarn and knitting methods also have a lot to do, at the same time, and use the speed of the centrifuge (centrifuge force), the performance of the filter material, temperature, etc all have much to do, so choose appropriate oneself condition and selection of the filter bag is a very complicated process. 

At present, the calculated diameter of equivalent volume particle is commonly used to represent its particle size. Expressed in m or mm.
