Dielectrophoresis electrode structure for emitting non-homogeneous electric field outwards

Abstract

The invention relates to a dielectrophoresis electrode structure for emitting a non-homogeneous electric field outwards. The dielectrophoresis electrode structure is characterized by comprising a first electrode plate and a second electrode plate; columnar protrusions and hole sites are evenly distributed on the first electrode plate and the second electrode plate, and the positions of the columnar protrusions and hole sites of the first electrode plate and the positions of the column protrusion and hole sites of the second electrode plate are complementary; after the protruding faces, with the columnar protrusions, of the first electrode plate and the second electrode plate are oppositely buckled, the columnar protrusions of the first electrode plate are embedded into the hole sites of the other electrode plate; the first electrode plate and the second electrode plate are connected with different output ends of a high-frequency alternating current power source respectively, and acting faces for emitting the non-homogeneous electric field outwards are formed on the non-protruding faces of the first electrode plate and the second electrode plate. By means of the columnar protrusions on the electrode plates, the electric field can be emitted to the outside of the acting faces without being closed between the electrode plates, and therefore the dielectrophoresis effect is enhanced.

Description

technical field [0001] The invention belongs to the technical field of material purification, separation, concentration and purification, and relates to a dielectrophoresis electrode structure that emits a non-uniform electric field to the outside. Background technique [0002] Dielectrophoresis (Dielectrophoresis—DEP) technology describes the translational motion of neutral particles in a non-uniform electric field due to the effect of electric polarization. The electrical characteristics of the particles and the suspended medium, that is, the parameters such as dielectric constant, conductivity, electric field strength, frequency, and viscosity of the suspended medium, so dielectrophoretic separation has higher selectivity; easier controllability; higher Separation and extraction efficiency. [0003] With the development of society and economy, the natural water is becoming more and more serious due to industrial and domestic pollution, and it is no longer suitable for di...

Problems solved by technology

In the process of osmotic concentration, serious membrane fouling, fouling and concentration polarization will inevitably occur, resulting in short concentration cycle, low efficiency, high cost and short service life of the membrane.
