Introduction
Bag filter is mainly composed of three parts:filter housing,stainless steel basket and filter bag.
Multi bag filter is suitable for large flow filtration,with quick opening design,it is very convenient to disassemble and replace the filter bags.It is suitable for occasions where needs a long time on the filter bag.The heating jacket design can meet high temperature liquid filtration process.It can maintain or increase the temperature of the fluid,prevent the fluid from solidification,improve the filtration speed of viscous liquid.
Working Principle
The liquid enters from the side or lower inlet of the filter bag.The filter bag is expanded due to the impact of the liquid and the uniform pressure surface.The liquid material is evenly distributed on the inner surface of the whole filter bag.The filtered liquid passing through the filter bag and flow into the pipeline.The particle impurities are intercepted in the filter bag.
