Description

[Detailed description of the invention]

The present invention relates to an electric field curtain element having electrostatic capability applying electric field curtain theory. Specifically, the present invention relates to an electric field curtain element having electrodynamic, electrostatic, discharge chemical functions, and physicochemical stirring functions. Conventionally, an electric field curtain element that applies a standing wave alternating unequal electric field (single-phase type) to the electric field curtain theory is a plate-shaped element with a group of linear ground discharge electrodes on its surface, or a plate-shaped A high (high) main induction electrode is provided, and a terminal of the high (high) induction electrode is provided on the back side of the element. Single-phase cross between both electrodes;
When an AL high voltage is applied, an alternating unequal electric field of standing waves is generated around the linear discharge electrode, and this action repels the charged object and brushes off the deposits on the surface. In this case, the deposit is contact-electrified by contact with the element surface and is subjected to the action of an electric field. Furthermore, when the voltage is increased, a strong alternating current creeping corona discharge is generated from the linear discharge electrode, forming a plasma containing abundant positive and negative ions, which becomes an excellent source of ions. In other words, when a charged object approaches the device, the charge is immediately neutralized (eliminated).
However, when an external electric field is applied, positive or negative ions are freely extracted from this ion source and the object is charged. We also modify the surface of the powder to increase its fluidity.
Promotes wetting to solvent. Furthermore, since strong ozone is generated as a result of this discharge, it can be used not only as an ozone generator, but also for sterilization, deodorization, reaction promotion, combustion promotion, desulfurization, and denitrification. The electric field curtain element that applies a traveling wave non-tube electric field (three-phase type) is a plate-shaped element made of high-purity alumina, and has a three-phase linear discharge electrode IJT, and a three-phase terminal on the back of the element. There are two types: one in which one phase of the three-phase electrode is exposed on the surface, and the other in which the needle electrode is buried inside the element. The former focuses on the ion generation effect, and the latter focuses on the electric field effect. This is what I put. Now, when a three-phase AC high voltage is applied from the three terminals to the three-phase electrode group, a traveling-wave unequal electric field is formed that moves in the phase forward direction along the surface of the element.Therefore, the element Most of the dust '4; object 1 first floats off the element surface due to electrical repulsion, and in that state is electrically and electrically transported in the direction of the traveling wave. In this case, the particles are
Not only that, but it can also be transported vertically. This traveling-wave unequal electric field consists of a rotating traveling-wave electric field (first mode) that travels in the phase forward direction, a reverse-rotating traveling-wave electric field (second mode) of slightly lower strength that travels in the opposite direction, and a rotating traveling-wave electric field that travels in the forward direction (second mode). 3
The rotating traveling wave electric field of the mode is expanded into an infinite number of separate rotating traveling waves, each with a different traveling speed and rotational speed. When the voltage is further increased, an alternating current corona discharge is generated on the element surface, and a plasma consisting of positive and negative ions is generated. Change the voltage

[As the temperature rises, the discharge becomes more active and the ion density of the plasma becomes even higher. Along with this, the electrodynamic action itself becomes active. In this state, not only is the dust transported, but by applying an external DC electric field, it becomes strongly charged during transport. It is also possible to drive guests in the direction of the Komi world, and it is also possible to modify the surface of powder. This invention provides an electrodynamic r

Alternatively, an axial groove may be formed in the center of the axial end of the blade body, and the blade body may be disposed in the solid dielectric body with an interval 11'>2 interposed between the blade body and the adjacent blade body.

Next, the configuration of the discharge electrode provided on the solid dielectric and the induction electrode provided as necessary will be explained with reference to the drawings.

There are various methods of applying the . In addition, the periodic varying voltage applied to the discharge electrode may include a single-phase or three-phase sinusoidal voltage at a commercial frequency or a higher frequency, a triangular wave AC voltage, a rectangular wave AC voltage, a repetitive pulse voltage, etc. It is possible to use Furthermore, in addition to 111f, a 1゛ electric field is generated by the alternating box complaint!

When the particles come in contact with each other, they become charged particles due to friction (f7 electricity, induction, charge injection, etc.).Then, these electric particles begin to oscillate electrodynamically along the lines of electric force.Also, This phenomenon is
Exactly the same phenomenon occurs when a particle that has been electrically charged in advance approaches the 111j unequal alternating electric field. For example, when the trailing collar is used in the field of angular powder or granular material, one or two types of powder or granular material supplied to the electric field curtain element 6 may be supplied to the electric field curtain element 6, or from the discharge electrode 8. When approaching an ion source generated by creeping discharge, the charge is immediately neutralized (eliminated). Due to the action of these 11.5" blades 1 and 2, contact between the powder and the ion source is carried out efficiently. At the same time, the same ridge as described above. Let's do some joint work. In other words, it is possible to mix two or more types of granular material while removing static electricity from the powdered wood. Moreover, in the case of one type, it becomes possible to prevent the formation of secondary aggregates of powder and granules. Incidentally, the -j method of the 1 fl diameter and length of each blade body, and the twist angle can be arbitrarily set, and an appropriate one can be selected depending on the field of use. Further, in the embodiment described in ``-'', the blade body is integrally shaped, but it may be formed by laminating a plurality of side plate-like elements obtained by dividing the blade body in the radial direction. Furthermore, the blade body is limited to one that is divided into two parts, as in the Nikiten example.For example, the blade body or the inside of the solid dielectric book cabinet is divided into three parts, and the blade body is spirally rotated by 6i1' (or 120°l) in the longitudinal direction. Alternatively, by cooling the inside or outside of the solid dielectric, it is possible to increase the power efficiency of ion generation.
