Bag filter is a common problem during use

Filter bag rupture is the most common problem with bag filtration technology and is divided into internal surface rupture and external surface rupture. Under the continuous impact of the feed liquid, the impurity particles carried by the feed liquid, especially the impurities with high hardness and irregular shape, cause continuous scratching on the inner surface of the filter bag, resulting in fatigue of the filter bag filter medium and damage. The outer surface is broken due to the continuous friction between the filter bag and the supporting filter basket. The space supporting the filter basket squeezes the filter medium on the outer surface of the filter bag, tearing the fiber structure of the filter bag and causing cracking. In addition, due to the defects in the design and manufacture of the filtration system, the filter bag and the filter basket cannot be completely fitted. When the filter material is washed under the filter, the longitudinal and lateral stress stretching of the filter bag is caused, which is also one of the factors causing the filter bag to rupture. .

Application prospects of bag filter before spraying

In summary, the pre-treatment of the automobile coating line has high requirements on the filtration system due to the large flow rate and complex composition of the liquid. The traditional bag filter technology can basically meet the requirements of modern coating line filtration. In the design, manufacture and practical application, the bag filter reflects the great advantages and cost performance of the traditional filter bag. Design and construction provide a better choice.
