How to electrostatically separate the fine mixture made of various materials , and apparatus for implementing the method

摘要

The present invention provides a method and apparatus for electrostatic separation fine granular insulating material of multi-valence. The method and apparatus, which has good properties, energy efficient and easy to adapt to the physicochemical properties the ambient environmental conditions, and the granules to be separated. The present invention relates to a method comprising the following steps. the stream of air fine granules mixture was defined by a) walls, the step of injecting the air flow between the two electrodes of the separation chamber having an air outlet and an air inlet, b) in various materials step to step to put, c) fine grain emerges into the airflow of turbulence mode, to control the air flow so that charged by the contact with the wall of the separation chamber and / or the contact of the fine between the two d) 2 in the direction of the electric field, fine granules were charged in step c), an electric field substantially vertically, or if the charge is negative if the fine is positively charged in the direction of the air flow between the electrodes step of collecting and discharge the fines adhering step of adhering to the surface of the electrode granules step of generating so as to move in the opposite direction, and e) charged and f) each electrode to.
