When the bag filter is used, the filter cloth is made of fibers, like cloth, so the filter cloth has a high degree of flexibility and ductility, and the filter cloth is in the bag filter. It can easily be damaged during use, especially when hard objects appear on the filtered material. When the filter cloth is punctured, the filter cloth will be worn when running, so that the filter will not be very useful.
The number of meshes in the bag filter is a very important parameter in the filter cloth. The size of the parameter indicates to a certain extent the number of filter holes in the filter cloth. The smaller the number of meshes in use, the more the bag filter is used. The larger the filter hole, the smaller the filter hole of the filter cloth. Therefore, in the process of filtering the material, the filter cloth with a small mesh number will cause many solids to pass through the filter cloth in the normal manner, so that the result is that the liquid after filtration is not crystal clear.
The bag filter works normally in the process of use, so it will need separate space on both sides of the filter cloth. When it is used, it needs the strong cooperation of the filter plate, and the edge of the filter cloth is effectively pressed on the filter. The edge of the board, the filter cloth is often larger than the filter board, because the bag filter expands the filter chamber, resulting in the filter cloth retracted to the filter room, so that the filter cloth does not play an important role, the natural filter effect will not be very good Now.
The bag filter first according to the chemical name of the fluid to be filtered, according to the chemical binding taboo to find the available filter material, and then for its operating temperature, operating pressure, pH value, operating conditions, one by one assessment, and remove the filter material is not applicable . Use is also an important consideration. For example, filters for pharmaceuticals, food, or cosmetics must be FDA-approved materials.
