Abstract:

In this thesis, by changing the filter overflow tube insertion depth of spin streaming filter, combined with the existing drip irrigation equipment change the structure parameters of spin streaming filter. Using Fluent software to choose reasonable turbulence model for numerical simulation analysis, contrastive research on the field test was carried on, reveals the relationship between the internal flow field pressure and the flow rate. The sediment production increased before they are reduced with the increase of the overflow tube insertion depth. It should choose the optimal insertion depth according to the specific use and usage model of hydrocyclone in actually use. The variation trend of internal flow field pressure and the flow rate when selected structural parameters changed are also analyzed. With the increase of insertion depth, the axial velocity and radial velocity of sand and water inside the hydrocyclone shows the tendency of decrease. Furthermore, the field experiment verifies the simulation result, thus proving the feasibility of using Fluent computational fluid dynamics software to simulate the internal flow field of the spin streaming filter. The research results will provide referential basis for the design and application of the drip filter system.
