Analysis of Horizontal Air-Separator Field of Municipal Solid Waste Based on CFD

Abstract:

The preceding separating technology of municipal solid waste is the premise and key to realizing waste comprehensive treatment and improving resource utilization. To the low efficiency of paper and plastic's separation, using the basic structural parameters of Horizontal air-separator, a finite element model is established based on Gambit software. Targeting at the pressure distribution and velocity distribution of the internal flow field under the condition of different wind direction and different wind speed, CFD is used for the analysis, and results shows that the wind angle between 15° and 20° and wind speed between 12 m/s and 14m/s is the optimum condition to get an ideal purity and efficiency of the light waste when winnowing domestic waste in the city of southern China.
