When it comes to filters, we have to mention bag filters.
Bag Filter is a new type of
Filter suitable for solid-liquid separation of difficult to filter suspensions, and has broad applications in environmental protection and chemical industry. In order to meet the various requirements put forward by various industries, various forms of solid-liquid separation and filtration equipment have emerged.
As far as filtration is concerned, regardless of the form of the equipment, there are no more than two types of bag filter filtration mechanisms:
1. At this point, the filter medium is very thin when carried out on the surface of the filter medium, and solid particles are trapped on the surface of the filter medium to form a filter, while the filtrate is separated through the pores of the medium layer
2. The filter medium has a certain thickness, and solid particles are mainly trapped inside the filter medium.
Both of these filtering mechanisms rely on the pressure difference between the two ends of the filtering medium, and there is no definitive boundary between the two, often coexisting. The filtration rate is generally related to the pore size of the filtering medium, filtration pressure, solid-liquid concentration of the suspension, particle size distribution of the solid phase, compressibility of the solid phase, and suspended gel. Currently, solid-liquid separation in environmental protection and chemical industry requires high accuracy, and the processed materials are often difficult to separate. The filtration equipment is required to have a simple structure, accurate and convenient operation, produce the filtrate as clear as possible, have a short initial filtration time, and have sufficient mechanical strength and stiffness. And it is required to carefully consider the chemical composition of materials from the perspective of economic benefits and quality control, and to complete the entire process in a sealed system. Bag filter is a new type of filter that can meet the above requirements and is suitable for solid-liquid separation of difficult to filter suspensions.
The filtration mechanism of bag filters is generally these, but in actual filtration operations, we need to conduct experimental research to have a clearer understanding of the filtration mechanism of bag filters.
