Sorting Mechanism and Airflow Simulation of Garbage Pneumatic Separator

Abstract:

In order to obtain flow rule and separation mechanism of garbage mixture particle in pneumatic separator, under the conditions of certain parameters and boundary, gas-solid two-phase flow mathematic model of garbage mixture particle was set up, FLUENT software was used to simulation and analyze the flow field of improved pneumatic separator, the separate track of particle in improved pneumatic separator was gained and performance of improved pneumatic separator was forecasted. Numerical simulation results show that the improved pneumatic separator has stable variation of pressure and velocity field. There not exist internal turbulence and back-mixing phenomenon and three particles with different qualities can be separated effectively. The numerical methods can be further optimized pneumatic separator and important theoretical foundation and technology method are provided for improving the structure and performance of pneumatic separator.
