Description

one

The invention relates to the field of separation of dispersed particles, but differing in dielectric and other dimensions or sizes.

A device for separating dispersed particles is known, which contains a microcell with two needle electrodes.

The aim of the invention is the separation of dispersed particles according to their dielectrophoretic mobility in a non-uniform electric field.

The proposed device is characterized in that one of the electrodes is made in the form of a tape along the side wall of the separation chamber, and the second EoTectrode is in the form of a series of needle electrodes in the opposite side wall, with the ends of the needle electrodes being located flush with the wall of the chamber.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a section along A-A in FIG. one.

The device consists of an inlet I, a separation chamber 2, electrodes 3 and 4, an injector 5 and a collector 6. Separation chamber 2 is a long (20-30 cm) flat (1-2 mm) channel of rectangular section between plate 1, 7, electrode 3 and plate 8 with needle electrodes 4. A collector 6 presents itself a plate 9, in which a row is made

the inclined channels 10 passing into the tubes 11, the carrier fluid along them and the separated fractions are diluted in tubes 12.

The described device operates as follows.

Injected through the inlet 1, the carrier liquid flows in a laminar flow through the separation chamber 2 and through the manifold 6 and the tube 11 is introduced into the oil tubes 12.

By connecting electrodes 3 and 4 to a source of high-frequency electrical voltage, a non-uniform electric field is established across the flow in the separation chamber. The mixture of particles is injected through the injector 5 into the stream of a low-conductivity carrier fluid (Yu-10-2) in the form of a thin stream 13, which, as it moves in a non-uniform electric ion, is separated by the action of a dielectric electrophoresis.

forces on a number of fractions 14, which are taken by collector 6 into test tubes 12.

Present Invention

A device for separating dispersed particles, containing a separation chamber with electrodes, an injector for introducing the mixture and a collector for sampling the separated fractions, characterized in that, in order to continuously divide the particle according to their dielectric constant and size, one of the electrodes

made in the form of a tape along the side wall of the separation chamber, and the second electrode in the form of a series of needle electrodes in the opposite side wall, the ends of the needle electrodes being flush with the wall of the chamber.
