Abstract:
A new process of plastics’ optimal separation from domestic waste is
presented, and principle and mechanism for separating plastics are
analyzed. A mathematical model of the separating process is established, and the effect of some parameters such as density, wind speed, sloping
angle of airflow and height of separating zone on the separating rate is
studied, then range of these parameters is determined. The test-beds for
plastics separating are developed and a lot of tests are conducted. The
rationality of this new study result is validated through tests, and the
structure and kinematics parameters of plastic separating equipments are
established, with an optimal 13~17 m/s wind-speed horizontally and 14o
blowing angle, thus presenting certain theoretical basis for developing
plastics separation equipment, so that the rate of separating plastic is
over 85%.
