Definitions
- the invention relates to a device for generating defined, ionized gases or ionization products and their lossless transport.
- Air ions Research into the biological activities of charged particles in air ions indicates a certain potential of their general biological, physiological and therapeutic effects. So far, it has been assumed that the biological effect of the air ions is achieved by regulating the membrane charge of the erythrocytes and acting on the central regulatory systems down to the brain and the glands of internal secretion.
- the use of air ions is known, for example, for diseases such as bronchial asthma, bronchitis, pneumonia, hypertension, etc.
- FR-PS 2 202 625 describes a method with which gaseous ions can be generated by a corona discharge.
- the large diameter of the supply tube creates a large volume flow. The consequence of this is that only relatively low oxygen anion radical generation can take place.
- a relatively high voltage is required, which contains a comparatively large amount of harmful by-products, e.g. Generates ozone. In this process, nitrogen must therefore first be ionized, with which the oxygen is then subsequently ionized.
- the object of the invention is therefore to create a device for generating defined, ionized gases or ionization products, in particular oxygen anion radicals, in which the production of harmful by-products is minimized at the same time, and to transport them almost without loss.
- the resulting defined ionized gases or gaseous products have a previously unknown physiological effectiveness. This is attributed in particular to the relatively high concentration of oxygen anion radicals generated. No or only small amounts of by-products, e.g. Ozone.

- FIG. 7 shows another possible embodiment of the invention
- FIG. 7a shows a view of the device according to FIG. 7 in the direction of the gas flow.
- FIG. 1 shows a device according to the invention for generating defined, ionized gases or ionization products, in which a gas stream 1 to be ionized enters a tubular, cylindrical hollow electrode 3.
- a high voltage supplied by a voltage source 2 is applied to the one-piece hollow electrode 3.
- This high voltage energetically excites the gas molecules flowing through before they reach the area of the inner electrode 4.
- the corona voltage can be reduced to 2.5 to 4 kV, whereby the formation of by-products, e.g. Ozone, values that are essentially not higher than those found in nature.
- the actual corona discharge takes place at the inner electrode 4.
- the outer electrode 3 and the inner electrode 4 are on the same or the inner electrode is at a lower, negative electrical potential. At least a portion of the inner electrode 4 is close to the gas outlet opening 9 of the outer electrode 3.
- the inner electrode 4 is formed in one piece and consists of a wire-shaped region 5 and a needle-shaped region 6, which lies close to the gas outlet opening 9, in order to keep the concentration loss of ionized gas molecules as small as possible.
- the size and shape of the inner electrode 4 is selected in relation to the inner region of the tubular outer electrode 3 so that it can ionize a large proportion of the gas molecules flowing through, so that defined ionization products are formed.
- the concentration and the qualitative composition can also be controlled via the flow rate of the gas molecules.
- the inner electrode 4 is held by supports 7 made of insulating material.
- the outer electrode is covered with an insulating touch protection 8.
- FIGS. 2 and 3 describe a device for generating defined, ionized gases or ionization products, which consists of a tubular, cylindrical hollow electrode 3 and two internal electrodes each.
- One inner electrode 10 is arranged in each case in the gas inlet area, the other inner electrode 11, 12 is arranged in the gas outlet area.
- the input inner electrode 10 serves for additional pre-excitation of the gas molecules.
- the ratios of the input and output surfaces of the hollow electrode 3 according to FIG. 3 are in a range up to max. 10: 1.
- a ratio of 2: 1 and 3: 1 has proven to be particularly advantageous.
- the internal electrodes 4 are designed either as a metal tip or as a wire mesh.
- a wire mesh instead of a wire mesh, of course, any equivalent embodiment can be selected.
- FIGS. 4 and 4a A further embodiment of the inner electrode as a wire mesh can be seen from FIGS. 4 and 4a.
- the wire mesh is formed by arranging individual wires in several parallel planes shifted at an angle. The number of wires used is variable. In Figure 4, four wires (13 a, b, c, d) are used. Figure 4a shows a top view of the resulting shape of the wire mesh.
- the diameter of the wire that forms the wire mesh is preferably in the range between 0.05 and 0.3 mm.
- the individual wires, which each form an electrode system, are advantageously arranged perpendicular to the gas stream 1.
- FIG. 5 describes a further embodiment of the inner electrode 4.
- the inner electrode consists of a base 14 and a cylindrical electrode body, which can have, for example, a round or pointed end.
- the base 14 is connected to the outer electrode 3 on the gas inlet side and has openings 16 through which the gas flow into the outer electrode 3 entry.
- FIG. 6 designates a device for ionizing gases, in which the outer electrode 3 is not formed in one piece, but is divided into several electrode areas.
- an outer electrode with three electrode regions 17, 18, 19 is used.
- the gas 1 to be ionized enters the outer electrode area 18 at the entrance area. This is connected to a voltage source U.
- the gas molecules excited in this way pass through a first grid-shaped or perforated inner electrode 21 and reach a second selection electrode area 19.
- a voltage U 2 different from U 1 is applied to this.
- the gas mixture flows through a third outer electrode region 20.
- a second inner electrode 22 mounted on the output side is arranged in this region.
- the area 20 is supplied with a voltage U 3 .
- All outer electrode regions 18, 19, 20 are separated from one another by insulation bodies 23.
- insulation bodies 23 For example, Teflon is used as insulation material.
- the pre-excitation of the gas can be further improved, for example by a higher negative potential with U 1 > U 2 > U 3 or U 2 > U 3 .
- metal in particular platinum, gold or copper
- metal is preferably used as the electrode material.

- the outer electrode 3 is connected to a voltage source 3, which supplies a high voltage of 5 to 12 kV.
- a fibrous inner electrode 26 is attached at one end to a support 7 and at the other end to the wall 25. Carbon is preferably selected as the material of the inner electrode 26, so that only low ozone formation and metal emissions can arise at the high voltage used.
