Different Blades And Filter-room Structures' Flow Field Analysis Of Rotating Filter Press

As the social and economic development, nation has advocated strongly the resource-saving and environment friendly social, and at the same time has put forward higher requirements to chemical, metallurgy and medicine industries. All these make rotating filter press has used widely because of the rotating filter press has many advantages such as continuous discharge slag, operation closed, and automatic control and lots of characteristics like high filtration efficiency, good concentration effect and lasting filtering so well accepted by enterprises easily. At the same time there is higher requirement to rotating filter press that is how to make it more efficient and less energy consumption.Rotating filter press's filtration efficiency and energy consumption are related closed to the flow filed in the filter room especially the tangential velocity which lead to sweeping flow force and the axial spacing, while at the same rotating speed the sweeping flow depends on the structure of blade, and the filter press's energy consumption are all in the rotating torque. In this paper the existing rotating filter press's first filter-room has been model and using the FLUENT soft to make simulation, with the different structure blades and axial space as the research objects, combining to the standard SIMPLE algorithm and standardκ?εturbulence equations to analysis the flow field and the torque value which to compare with experimental measured to clarify the relationship between flow field, the blade forms, filter-room's structure and energy consumption. So it will be the very important meaning to guide the rotating filter press design.
