Filter bag filter - Bag filter

Filter bag filter machineWorking Principle:

There are three types of suspension filtration methods: filter residue layer filtration, deep filtration, and sieve filtration. Filter residue layer filtration: In the initial stage of filtration, the filter medium can only retain large solid particles, while small particles pass through the filter medium with the filtrate. After the formation of the initial filter residue layer, the filter residue layer plays a major role in filtration, where both large and small particles are intercepted, such as in the filtration of a plate and frame filter press. Deep filtration: The filter medium is thick, the suspension contains fewer solid particles, and the particles are smaller than the pores of the filter medium. When filtering, particles are adsorbed in the pores after entering, such as in porous plastic tube filters and sand filters. Screening: The solid particles intercepted by filtration are larger than the pores of the filter medium, and the interior of the filter medium does not adsorb solid particles. For example, a rotary filter screen is used to filter out coarse impurities in sewage. In the actual filtering process, the three methods often appear simultaneously or sequentially. The liquid must overcome resistance when passing through the filter residue layer and filter medium, so there must be a pressure difference on both sides of the filter medium, which is the driving force for achieving filtration. Increasing the pressure difference can accelerate filtration, but particles that deform under pressure are prone to clogging the pores of the filtration medium under large pressure differences, resulting in slower filtration.
