DEVICE FOR SEPARATING PARTICLES IN ELECTRIC FIELD Russian patent published in 1994 - IPC

FIELD: electrostatic separation of particles. SUBSTANCE: device has diaphragm made of current-conducting material provided with holes, sucking-out contrivances and lower electrode rotation drive. Lower electrode is disposed at an angle to horizon and is made in form of a disk with polished surface. Upper electrode is made with concave working surface. Size of interelectrode space increases from the center of lower electrode to its peripheral parts. Suck-in branch pipes of sucking-out contrivances are mounted under the holes of the diaphragm except for the hole which is located in interelectrode space. Particle collectors, diaphragm and lower electrode are connected with earthed pole of power unit. EFFECT: improved efficiency. 1 dwg
